SELinux is preventing /usr/sbin/httpd from write access on the directory /var/www/moodledata.

Plugin: catchall
you want to allow httpd to have write access on the moodledata directoryIf you believe that httpd should be allowed write access on the moodledata directory by default.
You should report this as a bug.
You can generate a local policy module to allow this access.
Allow this access for now by executing:
root@localhost# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
root@localhost# semodule -i mypol.p

Conclusions:

EMC PowerPath for multipath I/O

2011-07-03T20:43:00.000-07:00

Overview

Multipath I/O is a fault-tolerance and performance enhancement technique in computer storage area networks, whereby there is more than one physical path between the CPU in a computer storage system. The physical multipath is through the buses, controllers, switches, and bridge devices connecting the mass storage.

Introduction
Data Center Scenario:

In our Main library data center environment, the same expectation of high system’s availability must be assured to minimize downtime and cutting mean time between failures (MTBF) on its 24x7 operations.Hence, the application services such as: e-lib, ilib, repository and kiosks that are link in a storage area networks required a set up of multiple redundant data paths (multipath) between a host servers and storage systems to avoid interruptions in data flow and anticipation if ever unexpected hardware failure occur. To manage a multipath I/O configuration, IT administrators should ensure that the server OS supports multipath I/O and is configured properly to access data from the storage system and fail over to secondary data paths when necessary.

Technology Implementation:

Our simple implementation of multipathing is using Dell EMC-500X which is connected to two Fibre Channel ports (FC1 -considered the fastest network carrier for large amounts of information) and the rest are physical path components, adapters, cables, and switches — to create logical paths between the server and the storage device. A network interface card (in the iSCSI case) or HBA should be connected by using redundant switch infrastructures to provide continued access to storage in the event of a failure in a storage fabric component. Should one controller, port or switch fail, causing the path to fail, multipathing logic uses an alternate path for I/O so that applications can still access their data. On the other hand the operating system can route I/O through the remaining controller transparently to the application, with no changes visible to the applications, other than perhaps incremental latency.

Option to Multipathing I/O:

There are two Linux multipath I/O available EMC PowerPath and DM multipath though both have each pros and cons; we preferred EMC Powerpath for a variety of ideal and practical reasons. Provide viable and robust multipath I/O capability for Linux operating systems on Dell PowerEdge servers and Dell/EMC storage systems. This multipath software layers can leverage the redundant paths to provide performance enhancing features, such as:

• Traffic shaping
• Automatic path management
• Dynamic reconfiguration
• Round-robin, adaptive failover
• Basic to advance automatic path failover
• Online recovery
• Supports heterogeneous OS(Windows®, Linux, UNIX®, and Novell NetWare))

PowerPath features:

PowerPath does not use a configuration file but rather it comes with its own init script and can be started and stopped from the command line. However, PowerPath relies on how the HBA driver has detected the LUN and created the block devices, and does not use an administrator-supplied configuration file; its enumeration of LUNs can vary from one node to the next in clustered servers. As with DM multipath, the configurations of the following block devices: /dev/sdb, /dev/sdc, /dev/sdd, and /dev/sde are all bundled to /dev/emcpowera. And once started, PowerPath gathers the UUIDs of the block devices and bundles the devices with the same UUID into a single device, /dev/emcpowerX. As PowerPath identifies the LUNs, it enumerates them as /dev/emcpowera, /dev/emcpowerb, and so on.

PowerPath Operations:

The PowerPath, administrators must stop all I/Os to the devices and unmount them just to confirm that all of the /dev/emcpowerX devices are not in use before issuing the command service PowerPath stop. This device can be partitioned, formatted with a file system, and mounted using the following cli commands: fdisk, mke2fs, mkdir and mount.

Powerpath Utilities:

The software features includes powermt, a powerful management utility for its devices. Its man page (man powermt) provides specific information about the utility. After installation, administrators can start PowerPath by issuing the command service PowerPath start. When stopping PowerPath, administrators should be sure that there is no I/O activity— that is, PowerPath should not be in use by any application. Other features of powermt is allowing administrators to display the current settings; set priority, policy (algorithms), and mode; remove a particular HBA or device; and restore a removed HBA or device.

Requriments:

OS : Centos 64 bit
DELL Servers
FC1 card controller

Fiber Optic Network cables
Lan Networks

Objectives:
To implement Powerpath in a Unix/Linux like platform
To implement EMC-Linux-5-1-0.194.rhel5.i386.rpm in an Intel 64 bit CPU architecture

Methodology:

Steps to make File Systems on Red hat Linux connected to EMC .To prepare the system and install PowerPath, follow these steps:

Below is the screenshot of the EMC PowerPath software’s availability; you may choose which version suits to your hardware architecture

EMCpower.LINUX-5.1.0-194.rhel5.i386.rpm (Intel chip 64 bit CPU architecture)

Step 1:
Set up the system for boot over SRP (SCSI remote Protocol-transferring and commands and data ->modprobe). When the system can boot over SRP, proceed with the steps below to get the system boot over PowerPath. First install below mentioned rpms:

1) EMCpower.LINUX-5.1.0-194.rhel.i386.rpm
2) Naviagentcli.noarch.rpm

[root@db1 ~]# rpm –ivh “rpm name”

root@db1 ~]# rpm -ivh EMCpower.LINUX-5.1.0-194.rhel.x86_64.rpm

[root@db1 ~]# rpm -ivh naviagentcli.noarch.rpm
Start two service mentioned below
[root@db1 ~]# /PATH_EMC/ service PowerPath start
[root@db1 ~]# /PATH_EMC/ service naviagent start
[root@db1 ~]# /etc/init.d/PowerPath start

Starting PowerPath:
done
[root@db1 ~]#

Step 2:

Edit the file /etc/redhat-release and put in the single line
[root@db1 ~]# Starting PowerPath: This package requires RedHat RHEL5."
Red Hat Enterprise Linux Server release 5 (Number of Powerpath version) so that the system is now identifying itself as a RHEL machine.

[root@db1 ~]# cd /etc
[root@db1 ~]# vi rhel5-x86_64

Change the Linux OS release version into the corresponding version of EMCpower.LINUX-5.1.0-
194.rhel.x86_64.rpm

Step 3:
Install PowerPath on the system. Follow the usual EMC PowerPath installation procedure to install PowerPath.

[root@db1 ~]# emcpreg -install (register powerpath)

This will ask you the key.

Please check this key installed on other server connected with EMC by cli command

[root@db1 ~]# emcpreg –list command

This will install key

Check that EMC path is now available or not by a cli command

[root@db1 ~]# cat /proc/partitions

You should see sd* devices in list, if not then reboot server

Step 4:
After PowerPath is installed properly and started, enter the fdisk -l command. You should see output similar to the example below. In this case, only one LUN is assigned to this host, and the LUN is partitioned accordingly.

[root@db1 ~]# fdisk -l

PowerPath is now up and running. The emcpowera* shows the PowerPath pseudo devices.

Step 5:
Creation of file system (Please skip or ignore this steps if it doesn’t support GPT use GNU parted instead)

This will temporarily mount FS
[root@db1 ~]# cat /proc/partitions

[root@db1 ~]# fdisk /dev/emcpowera

[root@db1 ~]# partprobe
[root@db1 ~]# pvcreate /dev/emcpowera1

32M is Physical extend

VOLUME_GROUP is volume group name
[root@db1 ~]# vgcreate -s 32M VOLUME_GROUP /dev/emcpowera1 204800 is size of file system that is 200(GB)*1024
[root@db1 ~]# lvcreate -L 204800M -n EMC /dev/VOLUME_GROUP
Mkfs.ext3 is used to convert the FS in ext3
[root@db1 ~]# mkfs.ext3 /dev/VOLUME_GROUP/EMC

Create mount point e.g. mysql on /
[root@db1 ~]# mount /dev/VOLUME_GROUP/EMC /mysql

Step 6:
Permanent mounting
[root@db1 ~]# edit /etc/fstab
[root@db1 ~]# cd /etc
[root@db1 ~]# vi fstab

/dev/emcpowera1 /emc ext3 auto, nouser, exec

Above entry in fstab will be active on reboot.

Reboot server

Check that FS “emc” is available by
[root@db1 ~]# df –h rw, sync

Step 7:
Testing mysql file copied to PowerPath

[root@db1 ~]# mount /dev/emcpowera1 /mnt/emc/

[root@db1 ~]# mkdir /mnt/emc/mysql
[root@db1 ~]# service mysqld stop
[root@db1 ~]# cp -R /usr/local/mysql/var /mnt/emc/mysql/

Step 8:
Proceed to EMC PowerPath productions.

Details:(1) LUN clustered configuration owned by SPA

Details(2):Basicj highly available SAN configuration with a LUN owned by SPA

EMC PowerPath Remarks:

After the evaluation of the requirements of implementing our storage area networks- multipathing, it is a clever option to proceeds on EMC powerpath features for a various supported reason. Based on our technical experience about practically and simplicity of usage we had dealt it greatly using EMC PowerPath.

Conclusions:

Successful deployment of EMC Power Path(Linux Version )

Mysql Workbench Setup (Fedora 64 bit)

2011-05-26T02:03:00.000-07:00

Introductions:

MySQL Workbench is a GUI database design tool that integrates SQL development, administration, database design, creation and maintenance into a single development environment for the database system of MySQL.It is a C/C++ program ,running in a multi-platform OS . The Software is now currently owned by Oracle yet most of its bundles are still available freely in the Open-source community.For further references please go to this wiki: http://en.wikipedia.org/wiki/MySQL_Workbench

Hey, I guess am seriously focusing myself into an information system of business data processing.Just recently when I got involved on using SQL and the combined front end software(PHP,PERL,Python,Gambas and etc.).But for now, this workbench is for sure a great help to simplify databasing scheme.

Anyway, sooner or later l'll stick to some of my own coding applications from basic ,average and might as well into wizardness-huh?

Then let's go coding...

Requirements:
Here are some important packages:
libzip-0.9.3-2.fc13.x86_64
python-paramiko.noarch 0:1.7.6-2.fc14
python-paramiko-1.7.6-2.fc14.noarch.rpm

For complete requirements(cut and paste then try it with "yum"):
mysql++-devel.x86_64 0:3.1.0-2.fc14
mysql-bench.x86_64 0:5.1.51-2.fc14
mysql-connector-c++-devel.x86_64 0:1.1.0-0.2.bzr888.fc14
mysql-devel.x86_64 0:5.1.51-2.fc14
mysql-embedded-devel.x86_64 0:5.1.51-2.fc14
mysql-server.x86_64 0:5.1.51-2.fc14
mysql-test.x86_64 0:5.1.51-2.fc14
mysql-workbench-gpl.x86_64 0:5.2.34-1fc14
mysqltuner.noarch 0:1.1.1-1.fc13
mysqludf_xql.x86_64 0:1.0.0-1.fc13

Objectives:

1*)Our objective is to simplify Mysql Database application with the aid of its bundled tools-Mysql Workbench

Methodology:

root@localhost# yum install libzip

root@localhost# yum install perpect

root@localhost# yum install python-paramiko

root@localhost# yum install mysql mysql-server

Install MySql source code
root@localhost# groupadd mysql
root@localhost# useradd -r -g mysql mysql
root@localhost# cd /usr/local
root@localhost# tar zxvf /path/to/mysql-VERSION-OS.tar.gz
root@localhost# ln -s full-path-to-mysql-VERSION-OS mysql
root@localhost# cd mysql
root@localhost# chown -R mysql .
root@localhost# chgrp -R mysql .
root@localhost# scripts/mysql_install_db --user=mysql
root@localhost# chown -R root .
root@localhost# chown -R mysql data

You can have the Mysql configuration optional
root@localhost# cp support-files/my-medium.cnf /etc/my.cnf
root@localhost# bin/mysqld_safe --user=mysql &
root@localhots# cp support-files/mysql.server /etc/init.d/mysql.server

Then check if MyQL is installed:
Note: What we're talking here is a default username and password just to check
mysql is running.You should see where MySql is,and start running its daemon, so here is how to do it..

root@localhost# whereis mysql
root@localhost# cd /usr/local/mysql
root@localhost# ./bin/mysqld_safe &

Open another tab and then go to the same path "/usr/local/mysql/" take note "./bin/mysql" (the dot for mysql/bin).Or to have a soft link to the executable path "/usr/bin/mysql)-that could be a better idea ..you know bro.
root@localhost# ./mysql
root@localhost# ln -s /usr/local/bin/mysql /usr/bin/mysql
root@localhots# mysql
"Bingo!!"

Then proceed to Mysql Workbench
root@localhost# rpm -ivh mysql-workbench-gpl-5.2.34-1fc14.x86_64.rpm

Then goto File->Programming -> Mysql Workbench

Detail(1) Go to the Mysql Download Area

My SQL saga is just beginning..

Conclusions:
Simply Mysql tools

RoBook Scanner Software (Beta Release)

2011-05-04T21:26:00.000-07:00

Introductions:

The initial effort to informally published a RoBook Scanner software engineering program will just tackle minimal infos.The purpose of this techno blog is a sort of an article for a reader to gain an idea.Idea that really means "pinoy can do it" ,due to some confidentiality of the project ,it is less expected to pull out the whole detail ; yet its explanations therein would be sufficient enough to deal what RoBook Scanner is all about.

The Author is hoping that in a given time 'if given an authority for publishing such systematic idea without hesitant it will be blogged with full detail -clearly and free to the public.But this time as the date of writings just simple documentation is sufficient to depict the contents of this article.

In some ways, this could be another fruitful sharing of thoughts for all of us-I wish that.

Hmmmn, anyway, the software now has done almost its features and the test is how can it be ported to different Linux flavour.So here is what I did for the software package installer .

Requirements:
Need to assure these are available or installed in your OS
Autoconf
Automake
Makepkg
Tar
deb helper

Objectives:
Compile a package installer
1) In Fedora

Remarks:
Hints:
Problem : Forbidden Error
Solution:
1.0) Do it always in README
2.0) If ever forbidden error (404,405,400,etc) occurs
2.a) take note the ownership of the /usr/local/svn (directory)
root@localhost# chown -R daemon:daemon /usr/local/svn
root@localhost# ls -alt
Then you should see ownership of the file

Solution:
2.b) check the apahce ownership!
Username daemon
Usergoup daemon

Solution:
2.c) Try to edit the
SVNPath not SVNParentPAth

2.d) and also don't forget to memorize your password
mkdir /usr/local/password
vim secret , then save
htppasswd -cm /usr/local/password/secret

In installing Subversion

Problem: "/usr/bin/ld: cannot find -lexpat "
Solution: download and install expat

Problem: configure: error: Cannot find libmysqlclient under /usr.
Note that the MySQL client library is not bundled anymore!
Note:
This happen because , we directly Yum installed mysql yet PHP now needs the complete path of MySQL- grrrr!

1) Be sure to download the mysql libraries and add ons:
mysql devel,mysql-php,libmysql

2) Use again "whereis"
root@localhost# cd /usr/local/php-5.version.xx
root@localhost# whereis mysql

Then use --with-mysql=/usr/bin/mysql libdir=lib64
root@locahost# ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/bin/mysql --with-libdir=lib64 --with-mysqli=/usr/bin/mysql_config --prefix=/usr/local/php --with-config-file-path=/usr/local/php --disable-cgi --with-zlib --with-gdbm
..and Yahoo it saves the day...

Conclusions:
Somehow it is always possible!

Remarks:

Hints:

1)If you have a G10 which has an older version firmware and you want to update it. Please go to this website and input the serial number of your G10,do it carefully by reading the instruction manual (PDF) to avoid damage in your camera

http://www.canon.co.jp/imaging/dcp/firm-e/psg10/download.html?Submit=Go+to+the+download+page

2) Remove the SD Card of your G10 camera it is necessary to avoid the mounting of G10 memory card drive (it will cause conflict in USB ID and ports).

3)If you can not use a mercurial downloader "hg clone" and its connection is being aborted to that google.code server -one thing is certain. You dont have the certificate to access its "https://" host server.Better install openssl first in your computer so that you can work smoothly to a mercurial copy or downloading.
root@localhost# sudo apt-get openssl
Warning!
if you would change your proxy then (1) reinstall your openssl , (2) delete the ssl certificate; otherwise you can't get the host server (for security reasons).

Zeroshell Innovation and Deployment

2011-02-28T18:28:00.000-08:00

Keywords: Ldap,Kerberos,proxy, captive portal,radius

Introductions:

Hello once again, as you would notice we had done a lot of service applications.I think its time for us to focus (or deviate our views ) on security and networking.Why? well simply because ,we just don't want it to be robust enough for a rigid applications but to secure our system with a centralized access-as our goal.This time we will be discussing a sort of making the safest system to make intruders or hacker wonders away from the scenes of our network confidentiality .Yet,with out the efforts of digging out deep knowledge on how to anticipate those intruders ,malicious access that will ruin our system in peril.Of course not only that , we need to monitor activities(logging) also on 24/7 basis ;for us to analyze rather determine if it is working smoothly or nobody will crash our system -as our assurance.

One thing which may follow is the outsourcing(research ) of appropriate software (which if free..) that will cater all our necessity and requirements.If you could still recall, we had previously tried different free application services on the net: pfsense,ipcop, drupal with chillihotspot and lastly the WifiAdmin.Well they been tested also as good as what they did promised, yet we needed these all to be in one package and Zeroshell have it all.

Zeroshell is a small Linux distribution for servers and embedded systems which aims to provide network services. As its name implies, its administration relies on a web based graphical interface. There is no need to use a shell to administer and configure it. Zeroshell is available as Live CD and CompactFlash images, and VMware virtual machines.Zeroshell is not based on an already existing distribution as for example Knoppix is based on Debian. The author has compiled the whole software of which the distribution is composed starting from the source code in the tar.gz or tar.bz2 packets. The compiler gcc and the glibcs of the GNU have been compiled too and have had the so-called phase of bootstrap in which they have recompiled themselves more times. This has been necessary to optimize the compiler and to eliminate every dependence from the glibcs of the system from which the first compilation took place. Some of the initialization scripts, as well as the guidelines followed by the author are those of Linux From Scratch. For a list of the used software look here.

Some of the innovations that we will aim for this free software are porting its applications to an embedded PC, a rack mounting deployment in our Data Center, then a quality testing on gateway and router applications and lastly to test rigidly all its features.

Best features of Zeroshell:
Captive portal
Radius
Firewall
Router/Bridge/Gateway
MRTG
LDAP
X509 certificates
QOS
Load Balancing
NAT

Requirements:

Phase I
PC (p4 or higher) Zeroshell server

Remarks:

Hints:
Please take note on setting up a wireless connection using Zeroshell:
Here are our cases:
Case I:
1)We don't have a preferred Altheros wireless card ,instead we will use the available WiFI-Access point.
2) We want zeroshell to captive our wireless clients before an Internet access .

(-)In doing so, our zeroshell will acts like a router/gateway .

1)Zeroshell : 192.168.0.1(internal IP address) ,as a router.
2)Disable the DHCP server of the Wifi Access point (WRTG54g) , make its IP address within the Zeroshell subnets.WRTG54g IP address must be in the subnet range which is assigned by Zeroshell that acts as DHCP server now.
Ex:
192.168.0.1/24 (Zeroshell)
IP address range
192.168.0.2 to 192.168.0.255

3)WRTG54g: 192.168.0.2 now acts as a client

4) Connect Zeroshell [192.168.0.1] ether port to WRTG54g LAN port not to its WAN port! (usually with 4 LAN ports)

5) Wifi-clients (PC or laptops) should be able to access the Internet at this time.
5.1) Refresh wifi network icon
5.2) Connect to the WRTG54g ssid
5.3) You must see a captive portal's login (as mentioned above)
5.4) Then bingo, you are now redirected to the www(:=))

Case II:
1) We want to directly connect clients to our networks permitted first by Zeroshell
2) Main router/gateway will broadcast IP address to our clients.

(-) In doing so we need to configure Zeroshell in a Bridge Mode setup.

Case III:
1) We want Zeroshell to do the authentication process using external LDAP
http://www.zeroshell.net/eng/qos/#Add-QoS-Class
(-) To do so, we need to configure FreeRadius server hard coded in our Zeroshell to use the LDAP backend instead, this is trough configuring FreeRadius script -radius.conf.
http://www.ibm.com/developerworks/library/l-radius/

III.1) Zeroshell uses freeradius which supports proxy and ldap integration.Find radiusd.conf and edit with vi or emacs ; uncomment the LDAP statement as necessary.

ldap {
server = FQDN for your server or IP address
login = ldap login looks like cn=?,o=?,c=?
password = ldap password
basedn = ou=?,dc=?,dc=?

III.2)To make it work. look for any other sections for ldap then uncomment it.Edit your dictionary.conf, make sure a Value of LDAP IS PRESENT if not add it in or uncomment it.

III.4)Look for users.conf and add the default entry for :
Auth-Type =: LDAP
Fall-Through = 1

Note:
For your LDAP server to authenticate then it should be ready to serve requests. So reestart freeradius service and Zeroshell should be checking with the ldap server for credentials.

Conclusions:
So far I considered zeroshell as a promising Linux software applications which is a complete embedded web security portal.

Knowledge Tree (Open source File Management System)

2011-02-09T22:12:00.000-08:00

Introductions:

Offices management almost requires an automated systems for an easy and fast transactions , a lot of files :contain different contents;name all of those and probably we will mention as many as we can(oh bulky files: receipt,appointment, voucher,cheque,release , issuance ,salaries and many to mentions-as I said).Hey, this great importance of file managements system sometimes or if not most of the times are not being adopted in the traditional work-flow of a local/common offices so why ?Well, despite the fact of such reasons behind necessity , still offices cant afford to implement the said system.Simply because , it involves huge amount of budget,or of course a financial buffer .Either purchasing it or paying for an IT programmers to have a defined or customized built in systems that will certainly suit s the requirements of office working flow -still needs huge capital.

But that not ends our aim to acquire such system, why? just an open-source will give(save) us a simple remedy ;and it is free for anybody who wanted to use it.

So ambitious as we are(no just trying),this techno blog will teach you a simple procedures the How-to of deploying free File Management system-yes brother its free.Just follow the steps and download each software packages (before I forgot your old PC can perform as an alternative sever for your DBase).Before proceeding , this tutorial will be using a Knowledge Tree Community Edition file management software.

KnowledgeTree is a provider of online document management software. The product makes use of the cloud computing platform from Amazon EC2. KnowledgeTree’s features — including workflow, document alerts and version control — are designed to help organizations manage business processes around documents in addition to enabling file sharing among teams. The service is available on a subscription basis.

There is also a free, open source community edition that is written in PHP and uses the Apache Web Server and MySQL database management system. A multi-platform installer provides end-users with a one-click install of both the underlying LAMP or WAMP stack and the application itself.

Repository Harvester(PKP & Google)

2011-02-06T20:53:00.000-08:00

Introductions:

Repository system is a bit challenge to the trend of online digital informations which are necessary to be integrated, and these are metadata,indexes or field link s to a searchable storage of archives.Just imagine a wide virtual system of one university library that could be a beneficiary to the other user/patron needs(researcher,teacher,students and other institutions) to get ample resources- electronic information. Given the available /free technology (Open source ) on the net and the knowledge of informations it is nowadays ' opportunity to unified every database of knowledge available elsewhere (World Wide Web).
If this is everybody's goal and we set this vision come into real , one thing we can invoke of having a unified opportunity of grabbing every archive or repository is by way of harvesting it. Yes brother we need to harvest those knowledge online and we need a harvester which is a free system-Open Harvester System
Open Harvester Systems is a free metadata indexing system developed by the Public Knowledge Project through its federally funded efforts to expand and improve access to research.

OHS allows you to create a searchable index of the metadata from Open Archives Initiative (OAI)-compliant archives, such as sites using Open Journal Systems (OJS) or Open Conference Systems (OCS).

Try this mysql safe comand to help solve that problem:
root@localhost# mysqld_safe
Try another CLI Tab
root@localhost# mysql -u root -p
..there you have it solved

Building a Web Search Engine

2011-02-01T17:23:00.000-08:00

Introductions:

I often think of google ,yahoo and other web search engines, actually I don't have any idea of those ,what I mean a deeper thought of developing it before.Until , little by little it would be a coincident now in my own scope of work.Yes, I am getting the idea that if I could run Zebra server together with its client (Yaz to be particular) I would be having a simple web search engine-think it ain't obvious. Ohhhm ...pretty cool ;of course that requires authentications and permission to the end(peer) server, and that is how these big web search engines are doing ( am correct?) .

In this case , we can refer this topic " Installing Zebra(z3950 protocol)" that I have blogged recently.

Apparently ,I have search out (wheew!) that we need other party to browse it via http (that is the new features of YAX 4.1.XX getting data via HTTP protocol-we'll see it brother!)and this is the job of SOLR application software.SOLR is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, and rich document (e.g., Word, PDF) handling. SOLR is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world's largest internet sites.

SOLR is written in Java and runs as a standalone full-text search server within a servlet container such as Tomcat. SOLR uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it easy to use from virtually any programming language. SOLR's powerful external configuration allows it to be tailored to almost any type of application without Java coding, and it has an extensive plugin architecture when more advanced customization is required.

Now let's have a try if this could make a straight forward approach on how to develop a simple search engine, again what we need is a server to host the records such as the meta-data/indexes and the client to communicate the server in a z3950 protocol way.

That is it for now.

Zebra Server -Index searcher (Z3950 protocol)

2011-01-04T01:01:00.001-08:00

Introductions:

A little story for this techno-server development,after eprints was set-up into a commercial grade repository the applications,customization and etc. We need some application services to to build along with eprints to port its records from another back up or a new storage server , and we must have marc21 protocol running into it. After marc21 was successfully installed/rebuild with eprints (thanks to the third party software-still an open source ), a need to harvest metadata is a must -that is polling the records /indexes to a remote new depository server - a harvester services; thus replicating a metadata from a remote eprints server . A triggering applications for a service engine to pulled indexes records and the solution to make it happen completely is non other than Zebra...

Zebra is a high-performance, general-purpose structured text indexing and retrieval engine. It reads structured records in a variety of input formats (eg. email, XML, MARC) and allows access to them through exact boolean search expressions and relevance-ranked free-text queries.

Zebra supports large databases (more than ten gigabytes of data, tens of millions of records). It supports incremental, safe database updates on live systems. You can access data stored in Zebra using a variety of Index Data tools (eg. YAZ and PHP/YAZ) as well as commercial and freeware Z39.50 clients and tool kits.

Zebra is free software, available under the GPL license. It may be used by anyone without charge. If you wish to incorporate Zebra into a commercial software distribution, please contact us about alternative licenses.

Notice: Optional, commercial support is available for Zebra.

Requirements:
Depository
Eprints (example with MARC(XML/ISO) protocol)
Koha

Methodology:
Download this prerequisite files:(incase you need a source build-rpm)
root@localhost# yum install gnutls-devel
root@localhost# yum install libicu-devel

For Centos Operating system
Download yaz src rpm(to date installation)
root@localhost# wget http://download.fedora.redhat.com/pub/epel/5/SRPMS/yaz-2.1.54-1.el5.1.src.rpm
root@localhost# rpmbuild --rebuild yaz*src.rpm
root@localhost# cd /usr/src/redhat/RPMS/i386/(in my case-Centos!)

root@localhost# rpm -ivh libyaz-2*
root@localhost# rpm -ivh yaz-2*
root@localhost# rpm -ivh libyaz-dev*

For Fedora Operating sytem
root@localhost# yum install libyaz libyaz-devel
root@localhost# perl -MCPAN -e 'install "MARC::Record"
root@localhost# perl -MCPAN -e 'install "MARC::Charset"
root@localhost# perl -MCPAN -e 'install "MARC::File::XML"
root@localhost# perl -MCPAN -e 'install "XML::Simple"
root@localhost# pelr-MCPAN -e 'install "Znet::Z3950::ZOOM"

Tar installations
Note:**
Since I was using an old Centos5 the best idZebra version which suits to version 2.44(idzebra-2.44.tar.gz).You can download it in the Zebra file/source archive.
Download idzebra-xxx.tar.gz file
Unzip and untar
tar zxvf idzebra-xxx.tar.gz
cd idzebra-xxx
./configure –help
./configure
Make
Make install

Or an options if you preferred directory
If you are not the system administrator, you can run zebra server from you home directory.
Run the following commands
root@localhost# tar zxvf idzebra-xxx.tar.gz
root@localhost# cd idzebra-xxx
root@localhost# ./configure –prefix=$HOME
root@localhost# make
root@localhost# make install

Directory Structure will be in..
$HOME/bin
Will have zebraidx and zebrasrv
$HOME/include
Include files
$HOME/share
Manual pages

Testing with MARC21
1) Goto the directory
root@localhost# cd idzebra-xxx/test/usmarc
You should see…
zebra.cfg (configuration file)
records (directory )
Note:
Records directory will be having a file called ‘sample-marc’
it contains MARC21 records in ISO-2709 format

Generating the Index
Run the following command
root@localhost# zebraidx update records
Note:*
Index files are created with the extension ‘.mf’ This is essential for search;Now you can start the z39.50 server

Starting Z39.50 Server
Run the following command
root@localhost# zebrasrv
You will see the following message
09:35:09-09/12 [log] zebra_start zebra.cfg 1.3.32
09:35:09-09/12 [server] Adding dynamic listener on tcp:@:9999 id=0
09:35:09-09/12 [server] Starting server zebrasrv pid=8856
1st Line: version number of the zebra server
2nd Line: zebra server is running on port 9999
3rd Line: Process id of program is 8856

And browse at
http://localhost:9999

Testing with MARCXML
root@localhost# cd test/marcxml
You will see marcxml files
m1.xml, m2.xml, m3.xml
Create a directory called ‘records’ and copy xml files into it
root@localhost cd records
cp *.xml records
Note:
In this case, each record is placed in a separate file, unlike the iso-2709 files where all the records are placed in one file

Testing (searching live!) from server to client
1) Activate the server
root@localhost# zebrasrv
If you want to update new marc records (well, we choose marc protocol)
root@localhost# zebraidx update records ( records here are the directory that
contains new upload *.marc files)

2) Windows client
Install Mercury 39.50(easy and fast for windows installations)

Configuring Mercury client

Edit for target Zebra Server

Options /setting for Mercury Database

Search entries (Title/Authors)

Displaying /parsing Marc records

Here is the log file in the Zebra server
20:44:27-12/02 zebrasrv [log] dict_lookup_grep:(\x01\x0A)(kuwerdas)
20:44:27-12/02 zebrasrv [request] search defualt OK 3 1 1+3 RPN @attset Bib-1 @attr 1=4 Kwerdas

3) Linux Client
Just type yaz client service
root@localhost# yaz-client
Z>
Then...
Z> auth "username" "password"
Z> open ip_address:9999
Z> scan

Note:*
You will see that Zebra server is responding every time the client request a command session - so observe it!

Remarks:
Sine I was installing two flavour (Centos & Fedora) I would chat down issues with regards to their installation problems:example (Net::Z3950::ZOOM)

Fedora
1) Installing YAZ is easy
root@localhost# yum install libyaz libyaz-devel
2) If you encounter problem " could not find /usr/sbin/ld -lwrap" problem (its library wrapper)
root@localhost# yum install " *wrap* " (there you can install all the file..)

3)Another is the decryption /encryption for YAZ -if this problem occurs , here is the solution for that.
root@localhost# yum install "*crypt*"
...and that would be fine any more and forever more !

Centos
1) Installing YAZ is difficult
Well to resolve: download the YAZ file from its source, be sure that your rebuild it completely and then install, and if not and try this to be safe.
root@localhost#yum install openssl openssl-devel readline readline-devel libtool
root@localhost# yum install rpm-build
then after it's solved -then that could be fine for YAZ installations.
root@localhost# rpmbuild --rebuild yaz-2.1.54-1.el5.1.src.rpm

If encountered Zebra mapping error(*.o or *.c or *.h)!
It usually happen when your YAZ files is outdated compared to a new source of zebra that you have. So, you must run concurrent dependencies to its equivalent machine core.

Index Data don't have the resources to build YAZ and Zebra for all RPM systems out there. However developer provide spec files that usually work.. Here's the procedure for building YAZ and Zebra for your platform (Fedora Core 1X on i386).

1)Uninstall ALL existing YAZ components that you got from
kojipkg. etc..
root@localhost # rpm -ve libyaz3
And other commands if you have other components (say yaz).

Now the procedure is as follows:

root@localhost# wget http://ftp.indexdata.dk/pub/yaz/yaz-3.0.47.tar.gz
root@localhost# rpmbuild -ta yaz-3.0.47.tar.gz
Note:
Please goto "rpm-build installation" if you can't build the yaz-source.Then,

root@localhost# ls /usr/src/redhat/RPMS/i386
root@localhost# sudo rpm - vi /usr/src/redhat/RPMS/i386/*yaz*.rpm

You have now installed all YAZ components including libyaz3-devel which
is required for building Zebra. Now download the latest zebra with this:
(just assuming the file version)

root@localhost# wget http://ftp.indexdata.dk/pub/zebra/idzebra-2.0.40.tar.gz
root@localhost# rpmbuild -ta idzebra-2.0.40.tar.gz
root@localhost# rpm -vi /usr/src/redhat/RPMS/i386/*zebra*.rpm

If the installation don't work-- then please re inspect the proceeding /instructions above(YAZ & Zebra installations)-maybe you have missed one!

Conclusions:

Fedora Core 1X Mirror Server

2010-12-04T00:16:00.000-08:00

Introductions:

Its been quite a while when Fedora Team had release a new OS/platform-version 14.Yet, some of the configuration for "yum" installations issues can not be resolved and the caused is the incorrect path of its mirrors and base url-(servers).And if it's left unconfigured then it seemed that you have not installed OS-useless!

So upon stumbled on this site,I now resolve this problem ever-hopefully.

http://digitizor.com/2009/06/17/how-to-fix-the-cannot-retrieve-repository-metadata-repomd-xml-error-in-fedora-11/

The recently released Fedora 14 Leonidas has some issues with it’s regular update process. Many users are getting a strange error which complains about the inability of the update system to retrieve the repository metadata, namely repomd.xml. You can see the error as attached in this inlet below:

Objective:

1)To resolve this errors

Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again

Requirements

When we tried to install Fedora 14 for the first time, we also faced a similar problem. A quick twitter search brought us to a conclusion that we were not alone. But a little tweaking of a few system files brought us back on track. In this article we tell you, how to go about resolving the problem in case you face it too.

Methodology:

You need to edit two of your repository files: /etc/yum.repos.d/fedora.repo and /etc/yum.repos.d/fedora-updates.repo. Now un-comment all the lines that start with the term baseurl and place a comment before all lines that start with mirrorlist. This should be done for both the above files.

Now edit your /etc/hosts file and append the following to it’s contents:

80.239.156.215          mirrors.fedoraproject.org
213.129.242.84          mirrors.rpmfusion.org

The other solution if "respomd.xml errror" still occur , try to browse the fedora mirror site then you will be redirected to your nearest countries mirror site and used it as your new " baseurl" in /etc/yum.repos.d/fedora.repo and /etc/yum.repos.d/fedora-updates.repo.

baseurl=http://ftp.yz.yamagata-u.ac.jp/pub/linux/fedora/linux/releases/$releasever/Everything/$basearch/os/

Remarks:

0) Please note that specified port(port :number 80/8080) must be open to at your http_proxy or ftp_proxy , else error pycurl 6/error # 14 will occur again and again.

root@localhost# export http_proxy=http://10.36.129.X:8080

1)Now try updating your system or installing any software via Yum. You will see, the error is now resolved and the error message is not shown anymore.

2) and please try this command if there is a failure and trying to find other mirror/s.

Package does not match intended download. Suggestion: run yum --enablerepo=updates clean metadata
root@localhost# yum --enablerepo=fedora clean metadata

3) The same procedure is also working with Fedora15

Conclusion:

This problem has now been resolved by the Fedora Community. But you may still not be able to download the updates properly from the mirrors due to the busy network and rush.

OSX Accounts(Add user/s & group)

2010-10-13T19:15:00.000-07:00

Introductions:
Recently , my task is to migrate eprints in MAC Xserve and it was running in OSX platform.I thought there would be no painstaking hardwork that I woud be experiencing-I was wrong.Though OSX is inheritance of UNIX , there were additional functions for MAC which UNIX had not or nevertheless unsupported.Some were : the CLI command , installer , and additional file folder exclusively for MAC ony.Yet, everything seemed ported well, except a more funnier thing was the adding of user and group account for eprints.And you know why? It wasn't just as easy as "useradd" or "groupadd" but a more little deeper config just to have a new user /group accont in OSX- I am telling you.
Adding a user is something easily accomplished using the built in GUI tools that ship with OS X, however any power user can appreciate the possible efficiency gained from using the command line. So in the spirit of efficiency here are the steps necessary to add a user to your Mac OS X system all with our good friend, Terminal.app.These commands need to be run as either the root user or with the “sudo” command. For more information on the sudo command see the sudo man page.

Objectives:
1) To have a procedure in adding accounts in OSX-MAX CLI
2) To have a procedure in adding accounts in OSX-GUI menu.

Requirements:
Any computer with running OSX operating sytem ofcourse -Apple bro...
And please visit this site http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man1/dscl.1.html

Methodology:
Copy and Modiy the MAC main tutorial

CLI Mode (shell command)
Create a new entry in the local (/) domain under the category /users.
dscl / -create /Users/eprints

Create and set the shell property to bash.
dscl / -create /Users/eprints UserShell /bin/bash

Create and set the user’s full name.
dscl / -create /Users/eprints RealName "UP Digital Repository"

Create and set the user’s ID.
dscl / -create /Users/eprints UniqueID 503

Create and set the user’s group ID property.
dscl / -create /Users/eprints PrimaryGroupID 1000

Create and set the user home directory.
dscl / -create /Users/eprints NFSHomeDirectory /Local/Users/eprints

Set the password.
dscl / -passwd /Users/eprints eprints1234
or
passwd eprints

If you would like UP Digital Repository to be able to perform administrative functions:
dscl / -append /Groups/admin GroupMembership eprints

Another CLI Mode

Create the group

Find out the next gid. If there’s not one higher than 501 use 501, otherwise add one to the greatest number in this list: nidump group . This will also do it and just return the highest currently used number nidump group . cut -d: -f3 sort -n tail -n 1

sudo nicl . -create /groups/mygroup

sudo nicl . -create /groups/mygroup grouppassword \*

sudo nicl . -create /groups/mygroup gid 508
Append users

sudo nicl . -append /groups/mygroup users rod

sudo nicl . -append /groups/mygroup users jane

sudo nicl . -append /groups/mygroup users freddy

repeat to fade
Change owner of a folder and all sub folders, files

sudo chown -vR :mygroup ~/myfolder

sudo chmod -R 775 ~/myfolder

Logout and back in again to get your credentials with the new group in it up-to-date.
Job done.

In GUI Mode (gui command)
You can create individual user accounts for each person who uses your computer. Each new user has a separate home folder and can adjust his or her own preferences without affecting other users.

Choose Apple menu > System Preferences and click Accounts.

If some settings are dimmed, click the lock icon and type an administrator name and password.
Click Add (+) and type the user's name.

If you don't want to use the short name generated automatically, type a new short name. (Once the account is created, you won't be able to change the short name.)

Type the user's password in the Password and Verify boxes.

Type a hint to help the user remember the password if they have trouble remembering it at login.

Click Parental Controls and select options to determine what the user can do with the computer.

If you change your mind while you're creating a new user account, click Delete (-) to cancel.

Summary:
It is quite cool simple thing but if left unresolved will be an enchant disaster.

Conclusion:
It is done

Decapod for RoBook Scanner

2010-08-03T09:07:00.000-07:00

Introductions:

So far I am having a hardly thoughts on how I could clearly grasped designing stereo camera to capture imagery ;perhaps, via software or driver .Although the allotted span of time would take only just for (one) 1 semester. Apparently ,I have had this topic on the other part of my web blog that deal solely to "RoBook Scanner" and I knew that the topic would be too lengthy if I would not include or separated Decapod discussions here.

Decapod is an Opensource project ,it is a software tools used in a book scanning and was sponsored by Andrew W. Mellon Foundation ; the project is being maintained by volunteers and dedicated people around the globe-kudos to them! Imagine how much is the cost of a commercial book scanning software? oh huge price. Anyway ,never mind because Decapod is free to everybody who aspire the best of its suited applications . Recently,I have included this project in my techno-blog because I considered it as one of the best freeware you can ever have for free .It is a combination of a different software programs which were intended and incorporated for book digitization.; and to mention those share & freewares: gPhoto, OCROpus, Image editing/cropping , kPDF and the server hosting too.

So am beleiving this was really a real open source community project -indeed.

I want to share here the steps in installing Decapod in Fedora version #13(the most recent release?) and Ubunto version 10.04 .I will try to test steps and find out if it would really give me a lucky try.

The last things to say is to get it done(OK here we go!)

Requirements:
Hardware:
2 Cameras (Canon G10 or the latest series)
Tripod or camera handler
Lamp variable lights ( to pre-scale ,shutter or luminance)

Software:
Ubunto 10.04

Decapod
-gPhoto
-Imagemagic
-OcrOpus
-genPdf
-Cherrypy

Objectives:
To Install Decapod and its modules
To setup decapod server
To stereo capture image using two cameras

Methodology:
Install tools and libraries
Download Decapod release version (0.4)
Run install script
Test decapod server
Test stereo camera capture

How-Tos:

Cool as ice book scanning

Simple NAT Server

2010-07-09T22:15:00.000-07:00

Introductions:

Hello folks, nice jotting again; I don't know if I would include this article until I needed it applications.How can I put external IP address with in my LAN so I must also have a local address.Simple NAT configurations will solve my problem with a little ease. It is because I am going to setup a live Asterisk VoIP Server one public and another one internal/private address.Public IP for WAN and Private address for my clients to get connected in the server.

A simple Network Address Translation will be doing the tweaking after I prepared a twon NIC (Ehternet) machine ofcourse running in CentOS -(common OS for Asterisk Telephony). I have encountered some issues with SIP to NAT but it can be done easy in SIP trunking configurations, and besides that IAX are much better in avoiding this NAT traversal configuration .

SO , I hope that there will be another applications yuo can use with NAT servering.

Objectives:

To use NAT in Asterisk WAN to LAN IP addressing
To be able to configure NAT traversal in some VoIP protocols (IAX,SIP,H323)
To learn NAT howto (NAT servering)

Methodology:

In doing this VoIP over NAT, we need to have Unix/Linux like OS that has a nat package in its kernel .We may also try to intall its software update if there is none in the OS software package-there are plenty files/program available for free download on the net.

Anyway,here is how to setup NAT with Linux and iptables; and I'll be mentioning a step-by-step tutorial to configure Network Address Translation (NAT) with Open Source Linux operating system and iptables. This will allow your system to act as gateway and to provide Internet access to multiple hosts in Local Area Network (LAN) using a single public IP address.

Requirements:

1. Hardware server with 2 (two) network interface cards (NICs).
2. Any Linux distribution (get more information at DistroWatch.com).
3. Linux kernel with networking and iptables support.
4. iptables package (you can find latest release at NetFilter's Download page).

Basic definitions

aa.aa.aa.aa is Wide Area Network (WAN) IP address (bb.bb.bb.bb is WAN netmask).
cc.cc.cc.cc is LAN IP address (e.g. 192.168.0.1 or 10.0.0.1), dd.dd.dd.dd is LAN netmask (e.g. 255.255.255.0).
ee.ee.ee.ee is default gateway for Internet connection.

eth0 is hardware name of the NIC connected to WAN base.
eth1 is name of LAN connected NIC.

Step-by-step set up

1. Apply two NICs to hardware server.
2. Verify that both NICs are recognized by Linux well and are fully workable:

# dmesg | grep eth0
# dmesg | grep eth1

the output may vary but in most cases it would be like following one:

#
eth1: RealTek RTL8139 at 0xe0830000, 00:30:4f:3b:af:45, IRQ 19
eth1: Identified 8139 chip type 'RTL-8100B/8139D'
eth0: link up, 100Mbps, full-duplex, lpa 0x41E1

Similar output should be for eth0 NIC.

To verify that NICs are recognized by Linux as networking devices use the following commands:

# ifconfig eth0
# ifconfig eth1

In case of success the output will be as follows:

# eth0 Link encap:Ethernet HWaddr 00:50:56:C0:00:08
inet6 addr: fe80::250:56ff:fec0:8/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:41 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

You can find full manual page for ifconfig command here.

3. Configure WAN interface (eth0) to get Internet connection:
ifconfig eth0 aa.aa.aa.aa netmask bb.bb.bb.bb

e.g.

# ifconfig eth0 123.45.67.89 netmask 255.255.255.248

WAN IP address and netmask should be provided by your ISP.

4. Set up WAN NIC settings to apply after server start up.
Configuration files containing NIC settings may have different syntax and location in various distributions. For such distributions as RedHat, Fedora, Centos and similar ones eth0 configuration file is at /etc/sysconfig/network-scripts/ifcfg-eth0. In Debian, Ubuntu NIC settings are located at single file /etc/network/interfaces.

To edit configuration files use any preferred text editor like vim, GNU nano or any other.

After editing /etc/sysconfig/network-scripts/ifcfg-eth0 should look as follows:

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=aa.aa.aa.aa # e.g. 123.45.67.89
NETMASK=bb.bb.bb.bb # e.g. 255.255.255.0
GATEWAY=ee.ee.ee.ee # e.g. 123.45.67.1
HWADDR=00:30:4f:3b:af:45 # MAC address (optional entry)

After making changes to /etc/network/interfaces section regarding eth0 NIC should looks like:

auto eth0
iface eth0 inet static
address aa.aa.aa.aa
netmask bb.bb.bb.bb
gateway ee.ee.ee.ee

Related links: detailed syntax description of /etc/sysconfig/network-scripts/ifcfg-ethN, manual page of /etc/network/interfaces.

5. Set up LAN NIC settings to apply after server start up. This step requires operations similar to previous step.

Edit /etc/sysconfig/network-scripts/ifcfg-eth1 and make sure that it looks like:

DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
IPADDR=cc.cc.cc.cc # e.g. 192.168.0.1
NETMASK=dd.dd.dd.dd # e.g. 255.255.255.0
HWADDR=00:50:8d:d1:24:db # MAC address of LAN NIC (optional entry)

If you are using Debian or related Linux distribution, edit /etc/network/interfaces (see previous step):

auto eth1
iface eth1 inet static
address cc.cc.cc.cc
netmask dd.dd.dd.dd

6. Set up Domain Name System servers IP addresses by editing /etc/resolv.conf:

#nameserver 203.145.184.13
#nameserver 203.145.184.12

7. Enable IP Forwarding:

# echo 1 > /proc/sys/net/ipv4/ip_forward

8. Set up NAT with iptables:

To delete existing rules from every iptables table, execute the following commands:

#iptables -F
#iptables -t nat -F
#iptables -t mangle -F

Related links: official iptables documentation.

Enable NAT by commands:

# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
# iptables -A FORWARD -i eth1 -j ACCEPT

8. Configure LAN clients to access Internet via described gateway:

Use clients' operating system tools to set up the following TCP/IP settings:

IP address: from the same network as cc.cc.cc.cc (you can use IP/Subnet calculator to get it)
Netmask: dd.dd.dd.dd
DNS: ff.ff.ff.ff
Gateway: cc.cc.cc.cc

Example:

#
IP address: 192.168.0.7
Netmask: 255.255.255.0
DNS: 209.160.67.13
Gateway: 192.168.0.1

2010-07-09T22:11:00.001-07:00

Introductions:

Our discussion here is all about an Opensource network monitoring software, no other than MRTG (Multi Router Traffic Grapher) which is an application that allows us to observe the traffic of a network. It generates html pages with graphs which are refreshed according to our network’s current state. Its source is written in Perl and C which means that it can be installed in every Operating System we like. We will also need SNMP daemon (Simple Network Management Protocol) which gives us information for a network. The following installation was accomplished under Linux and specifically CentOS . With some little changes it can be used and under other distros.We will present also some simple trick on how to monitor multi services (domain,IP,host,etc) in a single output page.It is not different with polling all the packets either from udp or tcp tunnel and let the sequence or arrangemeng followed to simple network management protocol-SNMP

I hope that this doc is easy for every reader to follow the howtos of deploying the MRTG server.

Good Luck to all Parekoy!

Objectives:
1)Basically we need to setup a network monitoring software
2)To use an Opensource MRTG which is durable and tested
3) To be able to configure and setup MRTG
4)To Monitor multiple traffic activities of different servers running in the productions

Requirements:
Some of the nescessary files need to create a graphical multi router traffic analysis are the following
SNMP-protocol
GD-graphics
LibPNG -libraries to *.png format
Zlib- some addons to graphics
Wget- uploading/downloading programs

Methodology:

Installation of SNMP server
Initially we install the packets needed for SNMP. Yum makes this job a lot easier.Next we make snmpd service to start automatically for the runlevels we want.

# yum install net-snmp-utils net-snmp

And we start the server.

# chkconfig --level 345 snmp

We can see that it is running in port 199.

# service snmpd start

# netstat -natv | grep ':199'

tcp 0 0 127.0.0.1:199 0.0.0.0:* LISTEN

SNMP Configuration
We run ‘snmpwalk’ which creates a “tree” of information for our network.
If you see an output like this one you may proceed with the MRTG installation. Else you should make some configuration first.

# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex

ip.ipAddrTable.ipAddrEntry.ipAdEntIfIndex.127.0.0.1 = 1

ip.ipAddrTable.ipAddrEntry.ipAdEntIfIndex.192.168.0.3 = 2

We keep a backup of snmpd.conf just in case anything goes wrong

# cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.origina

We open it

# nano /etc/snmp/snmpd.conf

find and change this line

com2sec notConfigUser default public

replace by

com2sec local localhost public

com2sec mynetwork 10.0.0.0/8 public

where 10.0.0.0/8 we put what our network is
find and change those lines

group notConfigGroup v1 notConfigUser

group notConfigGroup v2c notConfigUser

and replace by

group MyRWGroup v1 local

group MyRWGroup v2c local

group MyRWGroup usm local

group MyROGroup v1 mynetwork

group MyROGroup v2c mynetwork

group MyROGroup usm mynetwor

find and change this lines

view systemview included .1.3.6.1.2.1.1

view systemview included .1.3.6.1.2.1.25.1

and replace with this one

view all included .1 8

find and change this line

access notConfigGroup "" any noauth exact systemview none none

with those lines below

access MyROGroup "" any noauth exact all none none

access MyRWGroup "" any noauth exact all all none

Finally,find and change those lines

syslocation Unknown (edit /etc/snmp/snmpd.conf)

syscontact Root (configure /etc/snmp/snmp.local.conf)

with this one (but you can change those with your own settings)

syslocation Linux, CentOS

syscontact Your_name root@localhost

Running SNMP service

We restart the server to take affect of the notices

# service snmpd restart

And we run again

# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex

Now we should see something like that

IP-MIB::ipAdEntIfIndex.10.X.Y.Z = INTEGER: 2

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

Where 10.X.Y.Z is your ip address.

Installing MRTG application

Using yum...

# yum install mrtg

Configuration of our MRTG

We create the folder in which our graphs and html pages will be kept

# mkdir /var/www/html/mrtg/

And we run ‘cfgmaker’ for the configuration file to be created.

# cfgmaker --global "workdir: /var/www/html/mrtg" -ifref=ip --output /etc/mrtg/mrtg.cfg --global 'options[_]: growright,bits' public@localhost

Here you should pay notice to --output /etc/mrtg/mrtg.cfg as long as to public@localhost. With this command we tell MRTG to create a configuration file with the name ‘mrtg.cfg’ for the traffic of our computer (localhost). Instead of localhost you may put the address of any computer you may monitor as long as it runs SNMP.

Next we create our default index page

# indexmaker --output=/var/www/html/mrtg/index.html /etc/mrtg/mrtg.cfg

Configuring Apache To Work With MRTG

MRTG is useful because it can provide a graphical representation of your server's performance statistics via a Web browser.With newer versions of Fedora, Apache automatically reads the add-on files in the /etc/httpd/conf.d/ directory. With Fedora Core 1, you have to specifically configure the Apache configuration file /etc/httpd/conf/httpd.conf to find it. You can do this yourself by inserting this line at the very bottom of the main Apache configuration file before restarting Apache for the change to take effect. With Fedora Core, MRTG creates an add-on configuration file named /etc/httpd/conf.d/mrtg.conf that includes all the necessary Apache commands for MRTG to work.

[root@localhost]# include " /etc/httpd/conf.d/mrtg.cfg

Some configuration may need to be done, because by default MRTG accepts Web requests from the Linux console only. You can add your home network to the file by inserting the network on the Allow from line, or you can allow universal access by commenting out that line along with the Deny from line. This example adds access from the 192.168.1.0 network.

#Alias /mrtg /var/www/mrtg

Order deny,allow
Deny from all
Allow from localhost 10.36.128.0/32

If you want to access MRTG from the Internet, then you'll have to comment out the Deny statement and allow from all IP addresses:

#Alias /mrtg /var/www/mrtg

Order deny,allow
Deny from all

Note:**
Remember to restart Apache once you have made these modifications in order for these changes to take effect.

Compling MRTG configurations

We run the following command

# mrtg /etc/mrtg/mrtg.cfg

ERROR: Mrtg will most likely not work properly when the environmentvariable LANG is set to UTF-8. Please run mrtg in an environmentwhere this is not the case. Try the following command to start:

env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

In case you get an error like this;you have to run the above command more than once till it runs without any error. This is normal.

# env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

23-02-2007 17:28:53, Rateup WARNING: /usr/bin/rateup Can't remove localhost_2.old updating log file

# env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Finally we open our browser and type

http://localhost/mrtg

Multiple MRTG clients

The Fedora Core MRTG installation process creates a cron file named /etc/cron.d/mrtg. This file tells the cron daemon to run MRTG using the /etc/mrtg/mrtg.cfg file every five minutes to poll your network devices. You can configure MRTG to poll multiple devices, each with a separate configuration file. Here's how:

1) Create a new configuration file using the steps from the previous section; choose a filename that is not mrtg.cfg.

2) Add a new MRTG line in /etc/cron.d/mrtg for each new configuration file you create.

[root@localhost]# vi /etc/cron.d /mrtg

0-59/5 **** root env LANG=C /usr/bin/mrtg/  etc/mrtg/server1.cfg
0-59/5 **** root env LANG=C /usr/bin/mrtg/  etc/mrtg/server2.cfg
0-59/5 **** root env LANG=C /usr/bin/mrtg/  etc/mrtg/server3.cfg

3) Run the indexmaker command, and include all of your /etc/mrtg configuration files, to regenerate your Web index page.

[root@localhost]# indexmaker --output=/var/www/mrtg/index.html
/etc/mrtg/server1.cfg  /etc/mrtg/server2.cfg /etc/mrtg/server3.cfg

4) Other versions of Linux keep their MRTG cron entries inside the /etc/crontab file. Edit this file using the same syntax as the Fedora /etc/cron.d/mrtg file, and then restart the cron daemon to re-read the configuration:

[root@localhost]# service crond restart

You could also create a script with the /usr/bin/mrtg /etc/mrtg/device.cfg entries in it and make cron run it every five minutes. This way you can just edit the script each time you add a device without having to restart cron.

After the modification in our config, let's start snmp and apache

[root@localhost]# service snmpd restart

[root@localhost]# service httpd restart

Again, to see the multiple clients of our MRTG, we open our browser and type

http://localhost/mrtg

Online OPAC Automations

2010-05-20T02:25:00.000-07:00

Introductions:

We have now a software depositories ;what we want more are to tandem it with 'OPAC's and that our prospects -VuFind and Koha. Since Koha was very a prominent OPAC software I don't have a second options but to include it as a candidate for testing and evaluations .Another is the VuFind, as of now we have the impression that it has a more simplified version and is very promising software than its counterparts-well, let's see.

Let us first introduce Koha,this OPAC was originally developed for the Horowhenua Library Trust by Katipo Communications,New Zealand in 1999 (kiwi people). The first version of Koha went live at HLT in January 2005.And there are a lot of support being shared all around open source community with a dedicated team that enhance its bug , features and add-ons from time to time.

So now we proceed to actions ;debugging an OPAC powered by Koha-mwha!

Koha features:

-A full featured modern integrated library system (ILS).
-Award winning and open source no license fee, ever.
-Linux, Unix, Windows and Mac OS platform.
-Web Based.
-We can full integrate it into your website.
-Copy cataloging and z39.50.
-MARC21 and UNIMARC for professional catalogers.
-Tailored catalog module for special libraries.
-Use as a document manager or digital library.
-Manage online and off line resources with the same tool.
-RSS feed of new acquisitions.
-E-mail and/or text patron's overdues and other notices.
-Print your own barcodes.
-Serials management module.
-Full catalog, circulation and acquisitions system for library stock management.
-Web based OPAC system (allows the public to search the catalog in the library and at home).
-Simple, clear search interface for all users.
- Simple and comprehensive acquisition options.
- Koha is multi-tasking and enables updates of circulation, cataloging and issues to occur simultaneously.

Objectives:
To use Koha software package for online OPAC
To test Koha features
To compare Koha with VuFind
To evaluate Koha in production

Requirements:

Methodology:
Here are some straight forward method to succeed in installing,configuring and deploying KOHA.

1) Always be sure that compiler ,add ons are installed
2)In KOHA since it is a Web based application "perl" handles its Web GUI so we need to install also the libraries and included files
3)Mysql,SQlite also holds the applications of its databases
4)compiling ,installing and configuring KOHA
5)Trace the missing links of Yaz package

Remarks:

Well, one thing to note if the guide you are following does not continue as it was expected perhaps you should read now how the "config","make","make install" created an error display.
I would enumerate those possible problems:
1) Please identify each equivalent/appropriate version,what I mean is the contemporary dates when all of the the required packages were compiled and had worked out.

2)Please not some --prefixes (the correct path file installations)

3) You need to check if it needs you to setup environment variable or rather use "export"

4)Never ever forget to activate "MySQL" they must be running for such an applications to create its own database: field,name,tables ,user name, password -sometimes that was an inevitable case.

5)But in KOHA particularly, the tweak will much occur in the CPAN installations ; you can just cut and paste all the commands for eache package s to be installed by CPAN- and these were posted above. Try to force the installation if it does not continue on the first time of command of installing it. Otherwise it has other package dependencies needed to be compiled yet .Oh! this group of YAZ :applications(Yaz.x.y.z.tar.gz,libyaz.x.y.z and libyaz-devel.x.y.z) ,was a little bit confusing to mine so much so of its progress or development to CentOS ;painstakingly how can we find file just as where and how to fix its right version. I would rather suggest , why not KOHA used other package instead of YAZ ?I think there are alot of alternatives application in replacement to YAZ-the community should be serious about it though.

6) Here is another important tips for installing Net::Z3950::ZOOM is to try all available encryptor / decryptor in YUM. As different OS may vary names for these(so better try yum install *crypt*) instead. Perhaps also wrappers, I was enchanted resolving Z3950 files and turn it out installing this way -yum install *wrap* (oh thanks for a wild characters -KoHA is getting wild).

7)Please take note that if your web browser displayed errors "403" or "404" which mean to say that your apache web server (or common httpd) does not allow your koha url to be accessible (index.html-mainpage.pl).So try to add this line and I had my directory located here-> /usr/local/koha) and all the compiled packages.Please put and enclosing the statement below.
===================================
AllowOverride All
Options MultiViews -Indexes Includes FollowSymLinks
Order allow,deny
Allow from all
===================================
or this one
===================================
AllowOverride All
Options ExecCGI
===================================

8) Don't forget to create a "koha " database usually this is the primary cause of an error .It could be avoided this way-create a database first before installing koha.

Given:
Database = "koha"
Administrator account ="kohaadmin"
Hostname =" localhost"
Password ="password"

#mysql -u root -p
password (just press enter)

mysql>create database koha;
mysql>grant all privileges on koha.* to 'kohaadmin'@'localhost' identified by 'password';

9) Well , better install all the files required by CPAN

10) If you are using Fedora X.X version, make sure that selinux is disabled.

That is all folks!

Conclusions:
Its free but not the painstakingly hardship debugging its installations- make you stressed after a success

Customized Comercial Hi-Grade DSpace

Commecial Grade Repository(Eprints)

2010-05-04T19:29:00.000-07:00

INTRODUCTIONS:
So, we 've finally finished exploring EPrints ,and found out that it really fitted to the applications of a Digital Repository.

But we're not through yet or have done it almost if we would refer on a commercialize or high-end web data repository.There are a needs to dig out some configurations files: in its web-url, database format,scripts and etc.One thing more, the best way to customize eprints is not so much on GUI published management "Admin:Config tools" but rather on the files that can be found in its subdirectories.There are more shell commands found in the /usr/local/eprints3/bin that are used to change eprints file systems (GUI,DB,etc)

In this follow up blog-article will show us an interest much on branding ,deploying and configuring the system on our preferred setup and lastly we would be able to appreciate the digital repository sytem and so much so is the legacy of EPrints.

OBJECTIVES:
1) To use e-Prints in building digital repository
2) To fully costumize eprints in the organizational data structure repository design
3) To design library depository scheme/methods other than "Library of Congress Index"
4) To deploy hi-end fully costumized commercial digital repository

METHODOLOGY:
1)Branding
Login to Admin->Home then click edit image , the html source page can be edited.

2)Adding Views

3)Policy/Guidelines
Create your simple policy html files in a notepad , then copy it as "guide.html" in the directory/path below.
root@localhost # /usr/local/eprints3/archives/Archive_ID/cfg/en/guide.html

4) Work Flow(Type:Division:Subjects)

5)Crontab for active maintainance(script scheduler)

The system administrator is usually logged in as "root", but making changes to another user's crontab file or simply looking at another user's crontab file is often necessary. For situations like this, you can append the "-u" flag followed by the desired username.For example, if logged in as root but you want to edit the crontab for the user "admin", you would do the following:
crontab -e -u admin

Note** Now,I expect that you know how to access the crontab,let's take a look at the syntax of the crontab entry itself.

A typical crontab entry might look like this: 30 0,12 * * * /usr/local/eprints3/bin/

OK, so what does that mean? Well, there are 2 parts to the entry you see above. In fact, any crontab entry has 2 parts:

Part 1 - The setting the scheduler

The schedule, which governs when the task will run, consists of a string of numbers, possible commas and asterisks (*).So, in the above example, the schedule is:

30 0,12 * * *

What you are seeing is actually split up into 5 sections. The following chart illustrates what each section of the schedule is for:

1. Minute - Minutes after the hour (0-59).
2. Hour - 24-hour format (0-23).
3. Day - Day of the month (1-31).
4. Month - Month of the year (1-12).
5. Weekday - Day of the week. (0-6, where 0 indicates Sunday).

* = An asterisk in a schedule field indicates "every". It means that the task will occur on "every" instance of the given field. So a "*" on the Month field indicates the the task will run "every" month of the year. A * in the Minutes field would indicate that the task would run "every" minute. , = A comma is used to input multiple values for a field. For example, if you wanted a task to run at hours 12, 15 and 18, you would enter that as "12,15,18".

Let's take a look at how this format fits into the syntax of a crontab entry:

_________________________ 1.Minutes after the hour (0-59)
|
| ______________________ 2. 24-hour format (0-23).
| |
| | ___________________ 3.Day of the month (1-31)
| | |
| | | ________________ 4. Month of the year (1-12)
| | | |
| | | | ______________5. Day of the week. (0-6, where 0 indicates Sunday)
| | | | |
30 0,12 * * * /some/script/or/command

So, when we combine all the schedule elements, we know when and how often this task will run. Going on the above example, this task would run: At 30 minutes past the hours of 0 (midnight) and 12 (noon), EVERY day of the month, EVERY month of the year and EVERY day of the week. In other words, the above task would run every single day at 12:30AM and 12:30PM.

Let's play around with the schedule a little bit and try something different. What if we had something like this:

15,45 0,12,6 20 1,2,3 0 ./ /usr/local/eprints3/bin/generate_views mainlib

Let's decipher it...
15,45 - This means that the task will run at 15 and 45 minutes past the hour. But what hours and what days? Well, that's coming up.
0.12.6 - The task will run during the hours of 0 (midnight), 12 (noon) and 6AM.
20 - The task will run on the 20th day of the month. But during what months?
1,2,3 - The task will run only during the months of January, February and March.
0 - The task will only run on a Sunday.

So, when we put all of this information together,the task is going to run at 0:15, 0:45, 6:15, 6:45, 12:15 and 12:45 on the 20th of January, February and March IF that day falls on a Sunday.

Part 2: The task needs to be executed

In the above example, the "task" to run would be: ./ /usr/local/eprints3/bin/generate_views mainlib .
actually, we have a lot of scripts to run , and that can be found in the directory of /usr/local/eprints3/bin/

6)Back Up

New Server:
Let may give you some clear procedures to back up your eprints.In your old server to your new eprints server. Here is the link of my previous post with regards eprints installations.
http://cobecoballes-linux.blogspot.com/2010/04/e-prints-complete-metadata-repository.html

Given:
user name 'mainlib'
data base name 'mainlib_DB'
data base password 'xxxxyyy'

Old Server:

1)Please back up the following files: /usr/local/eprints3 ; /var/lib/mysql/mainlib_DB
root@localhost# tar zxf eprints_backup.tar /usr/local/eprints3/
root@localhost# mysqladmin -u root password "XXXYYY"
root@localhost# mysqladmin -u root -p create mainlib_DB
root@localhost# mysqldump --opt mainlib_DB > eprints_db.sql -u mainlib -p
root@localhost# scp eprints_backup.tar root@IP_NEW_SERVER:/usr/local/eprints3/
root@localhost# scp eprints_db.sql root@IP_NEW_SERVER:/var/lib/mysql/

New server:
1)Install the same version of eprints.ver.3.x in the new server ,see to it that you can point the name to the local browser after the installations: http://name.eprints (example only)

2)Copy those : eprints_db.sql eprints_backup.tar

root@localhost# tar zxvf eprints_backup.tar
root@localhost# mysqladmin -u root password "XXXYYY"
root@localhost# mysqladmin -u root -p create mainlib_DB
root@localhost# mysql-u root -p mainlib_DB < style="font-style: italic;">root@localhost# "mysql mainlib_DB "
root@localhost# mysql> grant all privileges on mainlib_DB.* to mainlib@localhost identified by 'eprints1234';

other'">

6) Upgrading repositories from an old to a new eprints version
root@localhost # cd /usr/local/eprints3/bin
root@localhost# sudo -u eprints ./ epadmin upgrade repository_id

7) Update eprints database structure to its latest meta-fields
root@localhost # cd /usr/local/eprints3/bin
root@localhost# sudo -u eprints ./epadmin update_database_structure repository_id

Importing and Exporting MARC protocol
Install the followiing perl modules for MARC
cpan > instal XML::SAX
cpan> install MARC::Record
cpan > install MARC::Charset
cpan > install MARC::XML
cpan > install MARC::File::XML

Note**
We can also you "yum" instead of "cpan" installation
ex:
root@localhost # yum install perl-MARC-XML
Then download the following files "EPrints-MARC_0.1.tar.gz" and extract it in the
root@localhost# cd /usr/local/eprints3/
copy the "marc.pl" file in the
root@locahost# cd /usr/local/eprints3/archives/Archived_ID/cfg/cfg.d/
Then goto eprints browser " manage depository" , [Import] and choose
"marc" then Bingoooo!

MULTIPLE EPRINTS REPOSITORIES(Virtual Directories)
o)Please follow the steps "CREATING AN ARCHIVE"
1) Create more than one archive
2) Give a DNS name for each archive

a) roots.localhost # /usr/local/eprints3/bin/ create epadmin engineering
a.1) hostname? engineering.mainlib.xxd.edu.ph

b) roots.localhost# /usr/local/eprints3/bin/ create epadmin mainlib
b.1) hostname? eprints.mainlib.xxd.edu.ph

REMARKS:

Hint!
If you had lost your "mysql" database root password elsewhere and your memories can't retrieve it any-more best thing is to these.

root@localhost # service mysqld stop

Rows matched: 2 Changed: 2 Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.02 sec)

mysql> exit

Bye

and you wouldn't be worrying any more.....alligator!

If Eprints is running yet some features are not available you may try to add some module or addons to supplement your requirements, and it is important to know if some software were installed already such as:

root@localhost# vim /usr/local/eprints3/perl_lib/EPrints/SystemSettings.pm
-------------------------------------------------------------------------------
'executables' => {
'convert' => '/usr/bin/convert',
'tar' => '/bin/tar',
'rm' => '/bin/rm',
'dvips' => '/usr/bin/dvips',
'gunzip' => '/bin/gunzip',
'sendmail' => '/usr/sbin/sendmail',
'unzip' => '/usr/bin/unzip',
'elinks' => '/usr/bin/elinks',
'cp' => '/bin/cp',
'latex' => '/usr/bin/latex',
'perl' => '/usr/bin/perl',
'pdftotext' => '/usr/bin/pdftotext',
'wget' => '/usr/bin/wget',
'antiword' => '/usr/bin/antiword'
},
-------------------------------------------------------------------------------
for example:Antiword for viewing pdf; to know if antiword is installed , pls type
root@localhost # which antiword
then must appear where the exectables is loaded
root@localhost# /usr/bin/antiword

After eprints migrations not all previous service are active ;therefore there is a need to familiarise the script in just to make it working again:
root@localhost # /usr/local/eprints3/bin
To change to a new apache configurations
0) root@localhost # ./generate_apacheconf archive_ID

To change new browsing
1)root@localhost # ./generate_views archive_ID

To change new text record
2) root@localhost # ./generate_abstract archive_ID

To restore a archives
3)root@localhost # ./generate_static archive_ID

For restoring thumbnail preview
4)root@localhost # ./epadmin redothumbnails archive_ID

To generate video preview
5)root@localhost # ./generate_video_preview

CONCLUSIONS:

DSpace Complete Repository

2010-04-27T08:45:00.000-07:00

INTRODUCTIONS:

After I have finished working on ePrints I will try another lucky shot with the DSpace setup and lay out an awesome comparison as to which digital repository will have the better performance in the said applications.Well, both of the software are good with the promising features of their own ;yet, whichever systems offer excellent as of the moment would be my option.After a final evaluations of the two digital repositories , the next steps will be the implementations of the system live in the productions .

DSpace was a very popular digital repository software because it was deployed in the productions earlier than its counterparts (ePrints,FEZ) .Not just because of that reason but the impression of the fact the MIT reputations had when it comes to IT software research & developments (RD) ;no more questions are necessary to be asked ;Technology wise-I bowed my head to these guys.Well, what is essential is the applicability of the design not only to the robustness , flexibility and technos involved in it but somehow an appeal(user friendly) that a software must have to the client/s in the industry, nothing else- the user.

I have two tutorials in this blog which are all about DSpace repository installations;First, I am going to discuss the old Dspace version 1.4 .X : 50 MB down to its oldest archives which were released prior to this date- 2007-5-10 .These files had a different directories contained in its folder compared to the latest DSpace files,the directories were arranged into different packages for each respective functions. Secondly,the next explanation is installing DSpace version 1.5 to the latest stable release which had an ad-ons advantages as compared to the old packages.One for example is the additional maven to tomcat ant, which will be used in documentations and customizations.The other add ons is the java dbc jar driver, these will not require installer to put *.jar files of java into DSpace , because the latter has now a built in *.jar during installation process.So now I have contemplated someting a little bit treaky about the DSpace installations as long as it is getting OK then it is getting harder .You like it?

Well, let us install the oldies first.

DSpace Requirements:
Apache
Apache-Tomacat-Ant
Java 5 SDK
Apache-Tomcat
PostGreSql
DSpace

METHODOLOGY:

Add paths to /etc/profile: nano /etc/profile
and add the following:

M2_HOME=/usr/local/apache-maven/
export M2_HOME
PATH=${PATH}:${M2}/bin

MAVEN_OPTS="-Xms256m -Xmx512m"
export MAVEN_OPTS

ANT_HOME=/usr/local/apache-ant
export ANT_HOME
PATH=${PATH}:${ANT_HOME}/bin

JAVA_HOME=/usr/local/java/
export JAVA_HOME
PATH=${PATH}:${JAVA_HOME}/bin

export PATH

Installing complete software package for DSpace(Linux)

1. Install Java 1.4 or later (standard SDK is fine, you don't need J2EE)

This step is required only if java is NOT already installed in the system
Download the RPM versions of java (e.g. j2sdk-1_4_2_04-linux-i586.rpm) and copy the file into Linux system.
You need to login as Linux root user to install
Use the command bellow to install

#rpm -ivh j2sdk-1_4_2_04-linux-i586.rpm
#rm /usr/bin/java [remove the original java binary if any]
#cd /usr/bin
#ln -s /usr/java/j2sdk1.4.2_04/bin/java java [create Symbolic link to newly installed java if any]

Define java home PATH by the commands:
- #JAVA_HOME=/usr/java/j2sdk1.4.2_04 [ java gets installed in /usr directory]
- #export JAVA_HOME
To set the environment variable JAVA_HOME permanently (get set at the time of system boot) do the following
- Open the file /etc/profile
- Add the two lines bellow at the end of the file.

JAVA_HOME=/usr/java/j2sdk1.4.2_04

export JAVA_HOME

Save the file, this will set the variable JAVA_HOME when system boots

2. Apache-ant installation

Check apache ant is already installed or not using the command: #which ant
You need to login as Linux root user
If not installed copy the file apache-ant-1.6.5-bin.tar.gz or apache-ant-1.6.5-bin.tar.bz2 to /usr/local directory
Use the following commands to install
- #cd /usr/local
- #gunzip apache-ant-1.6.5-bin.tar.gz or #bunzip2 apache-ant-1.6.5-bin.tar.bz2 (uncompress the file)
- #tar -xvf apache-ant-1.6.5-bin.tar (extract files)
- #mv apache-ant-1.6.5 apache-ant (rename the directory)
Define a path to the apache ant binary by the commands
- #PATH=$PATH:/usr/local/apache-ant/bin
- #export PATH
To add apache-ant path in PATH variable permanent do the following
- Open the file /etc/profile and add the two line below towards the end of the file.
- PATH=$PATH:/usr/local/apache-ant/bin
- export PATH
Save the file

3. Installation of Apache Maven (Optional but recommended)

Explanations : Maven is a extended toolkit of Ant and is used for documentations and downloading

You have to become root user to do the following
Download the file like apache-maven-5.0.28.tar.gz and copy to /usr/local directory
Do the following
- #cd /usr/local

- #mv apache-maven-5.0.28 tomcat [ rename the directory to smaller name]
Set the environment variable MAVEN_OPTS="-Xmx512M -Xms64M -Dfile.encoding=UTF-8" by doing the following
- #MAVEN_OPTS="-Xmx512M -Xms64M -Dfile.encoding=UTF-8"
- #export MAVEN_OPTS
To make it permanent do the following
- Open the file /etc/profile and add the two line below towards the end of the file.
- MAVEN_OPTS="-Xmx512M -Xms64M -Dfile.encoding=UTF-8"
- export MAVEN_OPTS

4. PostgreSQL installation

Installation From Source

You need to become Linux root user to install postgres
Download postgresql-8.4.4.tar.gz (or other versions of postgresql) file and copy to a directory where sufficient space available in your Linux system.

http://wwwmaster.postgresql.org/download/mirrors-ftp/source/v8.4.4/postgresql-8.4.4.tar.gz

Use the following commands to install
- #bunzip2 postgresql-8.4.4.tar.bz2 or #gunzip postgresql-8.4.4.tar.gz (uncompress the file)

Start posgres by doing the following
- $/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
- $/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data start
If you using postgresql version 7.x then do the following
- open the file /usr/local/pgsql/data/postgres.conf
- look for the line with text #tcpip_socket = false
- make it tcpip_socket = true and remove the comment
- Save the file
For 8.0+, in /usr/local/pgsql/data/postgresql.conf uncomment the line starting:
listen_addresses = 'localhost'
Open the file /usr/local/pgsql/data/pg_hba.conf and add a line
host dspace dspace 127.0.0.1 255.255.255.255 md5

in the section # IPv4-style local connections:

Create a dspace database, owned by the dspace PostgreSQL user by doing the following
- $/usr/local/pgsql/bin/createuser -U postgres -d -A -P dspace [Enter a password for the DSpace database]
- $/usr/local/pgsql/bin/createdb -U dspace -E UNICODE dspace

5. Installation of Jakarta Tomcat

Open the file /usr/local/tomcat/config/server.xml and do the following
- locate the following section

and add the line URIEncoding="UTF-8" in this section like

URIEncoding="UTF-8" />

#chown -R dspace.dspace /usr/local/tomcat [ change the owner and group of tomcat directory to dspace, so as to run as dspace user

Save the file

6. Installation of Dspace

You have to login as Linux root user
Create the DSpace Linux user by using the commands
- #/usr/sbin/groupadd dspace [create group]
- #/usr/sbin/useradd -g dspace dspace [ create dspace user]
Download the latest Dspace (dspace-source-1.x.tar.gz) file and copy the file to / directory
Do the following
- #cd /
- #gunzip dspace-source-1.3.2.tar.gz

CONCLUSIONS:

EPrints Complete Metadata Repository

2010-04-14T01:01:00.000-07:00

I would like to introduce my new task no other than exploring Web Metadata repository , a sort of Wiki database that our Institution needs to be implemented. So, I don't have the second thought to blog the progress here and as I knew this can be helpful to IT practicioner who required a likewise system . Actually there is another rival with the same approach of service -the DSpace (designed by an MIT Software Engineers), but as of now I keep my self sticking to this forum's review "http://www.oaforum.org/resources/tvtoolscomp.php" though I might consider comparing the two repositories as from time to time for they both have an excellent features to offer.

As of the moment , I am going to focus on E-Prints as it saying goes" E-Prints World's best practice"-well,let's see and I am a little bit excited.

1)Introductions:
EPrints is developed at the School of Electronics and Computer Science, University of Southampton, UK.

2)Objectives:

3)Review of related literatures

4) Requirements(Download & Installations):
Actually we have four(4) Software packages (including its addons)required to setup an Eprints repository
1)Apache (for Server)
2)Perl(Web Gui)
3)Mysql (Data base)
4)Eprints(Repository apps)

[ Tips on downloading: Tools and locations]
1)If we want to install all the included packages ,here is the direct link of e-prints' extra softwares:
http://www.eprints.org/files/tools/

2)But if you are deligent enough to download it one by one please goto to thier respective official sites:

3) Using Yum downloader/installer for the following addons
yum install lynx
yum install wget
yum install glib2-devel
yum install libxml2-devel
yum install glib-devel
yum install zlib-devel
yum install tetex-latex
yum install imagemagic
yum install libxml2-devel.i386
yum install perl-XML-Parser-2.34-6.1.2.2.1.i386
yum install perl-XML-RSS-LibXML
yum install perl-XML-Xerces
yum install perl-XML-Writer

4)Using cpan as perl addons downloader

wget http://cpan.uwinnipeg.ca/cpan/authors/id/T/TJ/TJMATHER/XML-GDOME-0.86.tar.gz

APACHE 2.X.X
root.localhost# yum install httpd
root.localhost# /sbin/chkconfig httpd one
-----------------------------------------------------------------------------------------------------------------------------------

1. Install Apache 2.0 or later

Apache is the most commonly used web server in the world, and it's free! EPrints requires Apache to be configured with mod_perl, as this allows Apache modules that are entirely written in perl, hence providing much improved efficiency.

Uncompress and extract the files using the command
- #tar -zxvf httpd-2.0.49.tar.gz
Go to the directory it creates like httpd-version
- #cd httpd-2.0.49
Run the following commands
- #./configure --prefix=/usr/local/apache2 --enable-so
- # make
- # make install
Open the file /usr/local/apache2/conf/httpd.conf and make the following changes (vi or any editor can be used to open file)
- Search and Replace www.new.com with IP address or hostname of your machine. Uncomment the line.
- locate the line #ServerName and Replace with your servername.
Start Apache Server by the command and check for the status of the web server
- /usr/local/apache2/bin/apachectl start
Open the browser and browse the default page at the URL: http://ip-no-machine-or-hostname/
If you are able to view apache page on your browser, it means that you have successfully installed Apache.

-----------------------------------------------------------------------------------------------------------------------------
MYSQL
root.localhost# yum install mysql mysql-server
root.localhost# /sbin/chkconfig mysqld on
------------------------------------------------------------------------------------------------------------------------------

Uncompress and extract the files by the command
- # tar -zxvf mysql-standard-5.0.xx-pc-linuxi686.tar.gz
Rename the folder it create like mysql-standard-5.0.xx-pc-linux-i686 to 'mysql' by the command
- mv mysql-standard-5.0.xx-pc-linux-i686 mysql
Create mysql group and mysql user to run database server as mysql user by the commands
- # /usr/sbin/groupadd mysql
- # /usr/sbin/useradd -g mysql mysql
Go to mysql directory using the command
- # cd mysql
Run the script to install MySQL database
- # ./scripts/mysql_install_db
Change the ownership and group of data directory to mysql
- # chown -R root data
- # chgrp -R mysql data
Start MySQL server by command
- # ./bin/mysqld_safe --user=mysql &

------------------------------------------------------------------------------------------------------------------------------
PERL
root.localhost# yum install mod perl
------------------------------------------------------------------------------------------------------------------------------

Uncompress and extract the files using the command
- # tar -zxvf mod_perl-2.0-current.tar.gz
Go to the directory it creates like mod_perl-version
- # cd mod_perl-2.0
Configure it for Apache web server using the command
- perl Makefile.PL - MP_APXS=/usr/local/apache2/bin/apxs
Run the following commands to compile and install
- make
- make install
Open the file /usr/local/apache2/conf/httpd.conf and add a line as shown
- LoadModule perl_module modules/mod_perl.so

------------------------------------------------------------------------------------------------------------------------------
GDOME
root.localhost# cd /usr/local/(here is the directory

Attempted to excecute rpm -Uvh gdome2-0.8.1-1.i386.rpm gdome2-devel-0.8.1-1.i386.rpm system reported failed dependancy glib2-devel >= 2.2.0 is needed by gdome2-devel
yum install “glib2-devel.*” (system installed glib2-devel.i386 0:2.12.3.2.fc6)
rpm -Uvh gdome2-0.8.1-1.i386.rpm gdome2-devel-0.8.1-1.i386.rpm (installed ok)
The following section is from the eprints wiki it outlines a bug that needs fixing

Fix the bug in gdome-config

To see if the bug is a problem run:

gdome-config --libs

If you get something like:

/usr/bin/gdome-config: line 86: --libs: command not found

/usr/bin/gdome-config: line 87: --cflags: command not found

then you need to fix the bug. Don't worry, it's easy.

As root edit /usr/bin/gdome-config

vi /usr/bin/gdome-config

Around line 88 find these two lines:

the_libs="$the_libs -L${exec_prefix}/lib -lgdome ` --libs` `xml2-config --libs`"

the_flags="$the_flags -I${prefix}/include -I${prefix}/include/libgdome ` --cflags` `xml2-config --cflags`"

And change them to this:

the_libs="$the_libs -L${exec_prefix}/lib -lgdome `/usr/bin/glib-config --libs` `xml2-config --libs`"

the_flags="$the_flags -I${prefix}/include -I${prefix}/include/libgdome `/usr/bin/glib-config --cflags` `xml2-config --cflags`"

Detail() First screenshot of Eprints

Detail() Manage depositing files

Detail() Modifying webpage layout

Detail() Modified and sample tested repository

5) Methodology /Howtos:

6) Scope of Works:
Build an Opensource ,online multiple multimedia repository(Eprints got it all!)

7) Evaluations and Testings:
Configuring the Metadata Repository
Configuring the MySQL dataBase
Authenticating Eprints

8) Remarks/Summary:

Well, after reviewing the use of Eprints as a repository Dbase(Mysql) ,apache configurations and downloading addons. Though I have already setup its GUI interface am still on testing the robustness of the system -just hang on for a moment and soon some feedbacks of mine will be posted again here.

Recently we've decide to deploy eprints into a productions and added remarks for the installations of eprints in a 64 bit quad core (Intel Xeon) server.Well,Its all about the software installations as much as possible keeping all the module installed could be a good habit, especially for a fast web browsing speed of eprints
perl-Atom, perl-RSS,perl-Ajax and etc.Apache writer also must enable (/etc/httpd/modules/*.o. Sometimes we keep on suspecting to anything that cause hard bugs into our system but it could be prevented if we could install all the modules requirements completely.

9) Conclusions:
Eprints meets all the requirements of a complete digital repository.

Thanks
