Nokia First Dual Sim in india

noreply@blogger.com (deepak) — Mon, 14 Jun 2010 18:27:00 +0530

Nokia has released their first Dual SIM phone C2 and C1-100

Nokia C1-100

By simply holding down a key, people are able to switch between SIM cards, meaning that they can take advantage of reduced call rates, flexibility when traveling from one country to another, or being able to share a phone within a family and still use their own SIM card. This is a great added convenience feature, considering the low price of the phone.”

The model C1 is a dual SIM handset, but only one SIM will work at a time. Simultaneous operation is not possible. You have to switch between the SIM cards for usage. The only advantage is that no physical SIM change is required.
C1-100 is a Series 30 device, comes with a s/by battery backup of 6 weeks, 500 phonebook entries and the standard features like FM Radio with 3.5 mm jack. The model will be available in blue, red, light grey and green colours , expected to be available by third quarter of 2010.

This handset is proposed to be available by the third quarter of 2010 at a price, a little over Rs 2090

Nokia C2

Nokia C2 is the advanced version of C1. Same as of standard Dual SIM handsets Nokia C2 offers the simultaneous usage of two SIM cards, means the incoming calls and text messages can be received to either number while the phone is on. The unique feature in this Dual SIM handset is the “hot –swappable” SIM card feature- This facilitates removal and insertion of SIM card when the phone is on.
C2 is a Series 40 device . The other features include 1000 entries phone book, 16.5 days long standby time, Bluetooth, GPRS and VGA camera, FM radio, Music player, Micro SD expandable upto 32 GB.

Nokia C2 is expected to be available in market by the last quarter of this year and it will cost around 35 to 39 Euros (Rs 1,998-Rs 2,215) excluding the taxes.

How To Create Linux LVM in linux

noreply@blogger.com (deepak) — Sat, 17 Oct 2009 17:13:00 +0530

What’s LVM? Why using Linux Logical Volume Manager or LVM?

These questions are not the scope here. But in brief, the most attractive feature of Logical Volume Manager is to make disk management easier in Linux! Basically, LVM allows users to dynamically extend or shrink Linux “partition” or file system in online mode! The LVM can resize volume groups (VG) online by adding new physical volumes (PV) or rejecting those existing PVs attached to VG.

let’s assume that

The LVM is not currently configured or in used. Having say that, this is the LVM tutorial if you’re going to setup LVM from the ground up on a production Linux server with a new SATA / SCSI hard disk.
Without a luxury server hardware, I tested this LVM tutorial on PC with the secondary hard disk dedicated for LVM setup. So, the Linux dev file of secondary IDE hard disk will be /dev/hdb (or /dev/sdb for SCSI hard disk).
This guide is fully tested in Red Hat Enterprise Linux 4 with Logical Volume Manager 2 (LVM2) run-time environment (LVM version 2.00.31 2004-12-12, Library version 1.00.19-ioctl 2004-07-03, Driver version 4.1.0)!

How to setup Linux LVM in 3 minutes at command line?

Login with root user ID and try to avoid using sudo command for simplicity reason.
Using the whole secondary hard disk for LVM partition:
fdisk /dev/hdb

At the Linux fdisk command prompt,
1. press n to create a new disk partition,
2. press p to create a primary disk partition,
3. press 1 to denote it as 1st disk partition,
4. press ENTER twice to accept the default of 1st and last cylinder – to convert the whole secondary hard disk to a single disk partition,
5. press t (will automatically select the only partition – partition 1) to change the default Linux partition type (0×83) to LVM partition type (0×8e),
6. press L to list all the currently supported partition type,
7. press 8e (as per the L listing) to change partition 1 to 8e, i.e. Linux LVM partition type,
8. press p to display the secondary hard disk partition setup. Please take note that the first partition is denoted as /dev/hdb1 in Linux,
9. press w to write the partition table and exit fdisk upon completion.
Next, this LVM command will create a LVM physical volume (PV) on a regular hard disk or partition:
pvcreate /dev/hdb1
Now, another LVM command to create a LVM volume group (VG) called vg0 with a physical extent size (PE size) of 16MB:
vgcreate -s 16M vg0 /dev/hdb1

Be properly planning ahead of PE size before creating a volume group with vgcreate -s option!
Create a 400MB logical volume (LV) called lvol0 on volume group vg0:
lvcreate -L 400M -n lvol0 vg0

This lvcreate command will create a softlink /dev/vg0/lvol0 point to a correspondence block device file called /dev/mapper/vg0-lvol0.
The Linux LVM setup is almost done. Now is the time to format logical volume lvol0 to create a Red Hat Linux supported file system, i.e. EXT3 file system, with 1% reserved block count:
mkfs -t ext3 -m 1 -v /dev/vg0/lvol0
Create a mount point before mounting the new EXT3 file system:
mkdir /mnt/vfs
The last step of this LVM tutorial – mount the new EXT3 file system created on logical volume lvol0 of LVM to /mnt/vfs mount point:
mount -t ext3 /dev/vg0/lvol0 /mnt/vfs

To confirm the LVM setup has been completed successfully, the df -h command should display these similar message:

/dev/mapper/vg0-lvol0 388M 11M 374M 3% /mnt/vfs

Some of the useful LVM commands reference:

vgdisplay vg0: To check or display volume group setting, such as physical size (PE Size), volume group name (VG name), maximum logical volumes (Max LV), maximum physical volume (Max PV), etc.
pvscan: To check or list all physical volumes (PV) created for volume group (VG) in the current system.
vgextend: To dynamically adding more physical volume (PV), i.e. through new hard disk or disk partition, to an existing volume group (VG) in online mode. You’ll have to manually execute vgextend after pvcreate command that create LVM physical volume (PV).

How to add route in Linux

noreply@blogger.com (deepak) — Sat, 19 Sep 2009 13:03:00 +0530

To view the current routing table run “route -n”

[root@klmppswdr01p ~]# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.41.42.0      0.0.0.0         255.255.255.0   U     0      0        0 eth0
10.41.41.0      10.41.42.8      255.255.255.0   UG    0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth0
0.0.0.0         10.41.42.1      0.0.0.0         UG    0      0        0 eth0

To add a route refer to the command below.

"route add -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8"

To delete a route refer to the command below.

"route del -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8"

The routing information above is not persistent across reboots. After a reboot, the routing information will be lost and you need to add them in again.

To make the routing information persistent, add the “route add” line as seen above into the /etc/rc.local file.

Sample /etc/rc.local file.

#!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local route add -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8

Linux File Structure

noreply@blogger.com (deepak) — Fri, 11 Sep 2009 20:43:00 +0530

For those of you coming from windows backgrounds, the way the linux filesystem is laid out may seem confusing at first glance…. but that is where this article comes in !

The first thing you should know when working with linux, is that everything is treated as either a file or directory. Yeap thats right, even hardware is considered a file by linux, and, speaking of hardware… all your hardware devices are located in the /dev directory, but more on that later.

Another thing that confuses windows users, is the fact that linux dosen’t use drive letters to distinguish between different partitions and devices. that is to say in linux, the “root” of your filesystem is / whereas in windows it would most probably be C:\ . Drives in linux are “mounted” to directories where their data can then be accessed, so for instance, if you needed to use your thumbdrive, you would plug it into your computer, and then mount it using the “mount” command, which specifies the path to the device ( something like /dev/sdb or /dev/sdc ) and the directory to mount it to (usually /mnt or /media), then you can happily access your drive from the /mnt or /media folder.

Sounds strange right? well yes it does if you come from a windows environment, where the entire operating system is consolidated onto a single drive. However, with linux and the ability to mount devices as directories, it gives the end user much greater flexibility in splitting up their operating system over several drives or partitions.

to understand what I mean when I say that this approach in mounting drives grants flexibility, I must first explain the different folders in linux and what they store

The graphic above shows the linux filesystem hierarchy, now will explain in a bit more detail what each folder contains.

/ this is the root folder, all other folders come under root.. think of it as C:\ in a Windows context.

/bin this folder contains all the user-essential binaries (programs) that are needed to administer and run your linux system… delete this folder and your system is broken.

/boot as the name suggests, this folder contains configuration files and other necessary files that are needed by the bootloader

/dev this folder contains device files (remember, these files represent physical devices, so be careful when working with them)

/etc this folder contains all the configuration files used by the system, you can also start and stop services (daemons ) from here

/home this folder contains the home folders of all the normal (non – root ) users on the system .. think of it as my documents in windows

/lib this folder contains software libraries

/media this is a mount point for removable devices… this is where you would usually mount your thumbdrives … etc

/mnt this is a temporary mount point

/opt this folder contains add on software (extra software)

/sbin this folder contains binaries that can only be run as the root user (”superuser”)

/tmp this folder contains temporary files that are erased upon reboot

/usr this folder and its subfolders contains user installed programs and utilities and libraries

/var this folder contains files that change alot (”Variable files”)

/root this folder contians the root user’s files

/proc this is a psuedo folder, that contains information about the linux kernel and hardware that is updated in realtime.

Now back to how mounting grants flexibility…

you see how the different folders all contain parts of the operating system? well we can actually mount a seperate hard drive for each of this folders. for example, your /home folder can be put on another harddrive than your / which means that you can easily recover your personal files if the harddrive on / fails because the harddrive mounted to your /home folder is seperate from the one that is mounted to your /

So there you have it, you now know a little bit more about the nuts and bolts of linux based operating systems.

SquirrelMail replaces Microsoft Outlook in the office of the Indian Prime Minister

noreply@blogger.com (deepak) — Thu, 2 Jul 2009 17:02:00 +0530

I have found the following interesting news from SquirrelMail.org’s website

(http://www.squirrelmail.org/index.php)
is enough to open eyes and minds of the government of under-developed countries (as ours), and a signal to act accordingly.

Here is the text directly from that site, from their News section.
NEWS: SquirrelMail replaces Microsoft Outlook in the office of the Indian Prime Minister

Mar 25, 2009 by Paul Lesniewski

Several news outlets (Techgoss, infopackets, The Register, The Times of India, etc.) are reporting that after a virus prevented email retrieval for three months in the office of the Prime Minister of India, SquirrelMail was chosen as part of a replacement system that had previously been based on Microsoft products. This surely means that several other Open Source products were included in the switch, and we applaud both the Office Of the Prime Minister and its technology consultants who made the switch to Open Source Software

Uninstalling Linux

noreply@blogger.com (deepak) — Thu, 2 Jul 2009 16:58:00 +0530

Hi,

In this HOW-TO i'm going to try to explain how to uninstall linux without messing up your windows partition. I feel this is a area that isn't really touched upon that much and most newbies need help with it. I know when I was a noob I didn't like linux because I hadn't knew how to uninstall it. But now I feel I know enough to write a tutorial on how to do it and explain the steps.

1. Removing Your Disto

The easiest way uninstall linux is probably from a Windows XP CD. Once you boot from the CD follow the instructions until you get to the part where you see all the partitions on your hard drive. You must delete all your linux partitions. The primary partitions you'll probably see are

linux ext3, linux ext2, linux swap.

You should delete all these partitions to remove your distro.

2. Fixing your Master Boot Record

Most people know how to uninstall their distro. But afterwards their presented with a black screen and grub asking for input

grub>

or something similar to that. This is were I got totally confused when I was first starting linux. I had no idea what to do so I just re-installed my distro, which actually fixed the problem but I wanted linux totally gone. Enough about me let's get back uninstalling linux. Boot off the Windows XP CD and after windows loads type r to get to the Recovery Console. Once you in the the Recovery Console you'll probably be prompted to type the administrator user name and password. I ususally just put admin as the user name and nothing as the password and it usually works. But that is just my settings your might be different, but usually admin and no password works fine . Now were in recovery console all we have to do is type:

fixmbr

this command will re-write the Master Boot Record, therefore removing Grub.

3. Finished

Now just type shutdown -r this will restart the computer. Remove the Windows XP CD. Now when the computer starts you should be greeted with the all familiar Windows Startup Screen.

Red Hat Configure an NTP Client And Server

noreply@blogger.com (deepak) — Fri, 20 Mar 2009 19:21:00 +0530

how do I configure an NTP (Network Time Protocol) client or server under CentOS / RHEL / Fedora Linux to manage the system clock over a network?

The Network Time Protocol (NTP) is used to synchronize a computer's time with another reference time source. Under CentOS / RHEL you can use NTP or OpenNTPD server software. Both package provides client and server software programs for time synchronization.

Install ntp

The ntp package contains utilities and daemons that will synchronize your computer's time to Coordinated Universal Time (UTC) via the NTP protocol and NTP servers. The ntp packageincludes ntpdate (a program for retrieving the date and time from remote machines via a network) and ntpd (a daemon which continuously adjusts system time). Install the ntp package:

# yum install ntp

How do I configure an NTP Client?

Simply open /etc/ntp.conf file, enter:

# vi /etc/ntp.conf

Make sure the following line exists:
server ntp.server.com

Where,

* ntp.server.com : the hostname or IP address of the site NTP server. If your ntp server located at 172.16.168.5, enter server 172.16.168.5. You can also use public ntp server located at ntp.org.

You can also run ntpd using cron:

# echo '30 * * * * root /usr/sbin/ntpd -q -u ntp:ntp' > /etc/cron.d/ntpd

he above instructs crond to run ntpd and after setting the clock just exit, and the -u option instructs it to run as the ntp user.

----------------------------------------------------------------------------------------

Configure an NTP Server

Our sample setup:

172.16.168.5 ==> CentOS / Fedora / RHEL NTPD Server.

First, install and enable ntpd on 192.168.1.5:

# yum install ntp
# chkconfig ntpd on

Now open /etc/ntp.conf:

# vi /etc/ntp.conf

Make sure the following line exits:
restrict default ignore

Above will deny all access to any machine, server or client. However, you need to specifically authorized policy settings. Set it as follows:

MuCommander is a powerful, cross-platform file manager

noreply@blogger.com (deepak) — Sat, 25 Oct 2008 11:28:00 +0530

We've covered many, many Explorer replacements here in the past, so I was a little surprised that MuCommander hadn't been written up yet.

What makes MuCommander stand out is that it is free, open source, and cross-platform. The author's web site provides downloads for Windows, Mac, and Linux (.tar.gz) as well as a Debian package, portable version, and a Java Web Start package.

It's actually the first JWS application I've come across since I started reviewing for Download Squad. It loaded fairly quickly on my netbook, and ridiculously fast on my quad-core AMD desktop.

MuCommander presents a skinnable, dual-pane view for file management. There's no tab support, though I don't consider that a major shortcoming - especially considering its other features are numerous, and extremely useful.

For starters, there's built-in support for FTP, SFTP, Samba, HTTP, NFS, and Bonjour. Several types of archives can be explored without extracting: zip, rar, tar, gzip, bzip2, iso, nrg, deb, and lst. MuCommander can create archives (press ctrl+I to pack) and even modify zip files on the fly without having to recompress the entire archive

There's also a command shell window with scrolling output, credential manager, and favorite locations list.

MuCommander is a fantastic file manager, and well worth a test drive for any user - regardless of OS.

RevoluTV: Watch live TV streams in Windows

noreply@blogger.com (deepak) — Sat, 25 Oct 2008 11:25:00 +0530

Hulu Schmulu. Some TV networks have been providing streaming content for ages. You can watch live or recent news updates from the BBC or CNN, music videos, or even movies if you know where to look. But where's the fun in that? RevoluTV is a Windows app that comes preloaded with a long list of video channels that you can stream using the built-in Windows Media Player interface.

Unlike previously mentioned LiveStation, which is mostly focused on news channels, RevoluTV has a ton of streams divided into categories like News, Entertainment, Lifestyle, Music, Movies, Sports, and Kids. And most of the streams I tried actually played, which is more than I can say for some other programs I've used that promise to let you stream internet TV content from around the globe.

Of course, I've kind of gotten used to the video-on-demand feel of Hulu and similar sites, so I'm not really a big fan of watching live television anymore. But if you can't find anything worth watching on Hulu, YouTube, or whatever online video site you're addicted to these days, RevoluTV might be worth a look.

15 Tips For a Better Linux Experience

noreply@blogger.com (deepak) — Wed, 15 Oct 2008 18:11:00 +0530

The beauty of Linux is in users ability to do large amount of customization to have a unique user expereince. So today we will look in to some tips for a “better” Linux experience. The term “better” here is relative, because what works for me might seem a distraction for some or plain annoying to others; some of this “tips” might appeal to beginners, while advanced users might find it too easy. Hopefully some of these tips will be helpful to some of you.

1) Turn on your computer remotely by sending “magic network packets” to WakeOnLan supported network cards. This can be very helpful if you run a server at home but only access it occasionally. There is no need for you to have the server running all the time.

2) If you dual boot with windows, accessing Linux file system from your windows installation might be important for you. There are three windows applications that can help you do this: Explore2fs, Ext2 Installable File System, DiskInternals Linux Reader.

3) Similarly to have read/write access for Windows NTFS file system, you can use NTFS-3G. Most recent popular Linux distribution has NTFS-3G installed out of the box.

4) Share a single mouse and keyboard with multiple computers with different operating systems, each with its own display, with support for copy and paste. Thanks to Synergy, the most popular free KVM software switch out there.

Synergy in action.

5) Recovering data from damaged media can be handled by several Linux tools including some LiveCD, specifically built to help recover data. Parted Magic, Ubuntu Rescue Remix, SystemRescueCd, Foremost (data recovery), Ddrescue.

6) If you are a blogger like me and enjoy using desktop client over web editors, you will find these clients useful: Gnome Blog, Drivel Journal Editor, BloGTK, Thingamablog, Bleezer, QTM.

7) If you are a webdeveloper/designer, you will often find yourself testing a website across many platforms and browsers. IEs4Linux is a great painless way to check how IE browser will render your website. You could use services like browsershots, but I had mixed results with them.

8) Does your iPod miss iTunes? Here are three itunes alternative which will do most of what your iTunes would do, not an exact replacement; but does the job: Amarok, Banshee, Rhythmbox.

9) Follow multiple files by creating multiple windows in your console with the help of MultiTail, also known as tail on steroids.

10) Use Terminator to split your screen space with many terminal windows, both horizontally and vertically.

11) For even better control over your terminal display and customization and complex functions, GNU Screen is a much better choice over terminator; however terminator serves only one purpose.

12) Use RSIBreak to help prevent Repetitive Strain Injury. RSIBreak will force you to take short break, depending on your configuration, so that you don’t over-work yourself.

RSIBreak

13) If you find yourself working on a dumb terminal (hello sysadmins) or prefer working on terminals, you will find newsbeuter to be an excellent RSS reader for the console.

14) I know some will disagree with me on this, but conky is an excellent compliment to your desktop experience. If properly configured, it can add a lot of value to your desktop environment. Check out this very creative conky setup and read about it here.

15) Do you do podcasts? rootprompt has a great article with huge resources for both Linux podcasters and listeners.

Run Linux LiveCDs in Windows with MobaLiveCD

noreply@blogger.com (deepak) — Thu, 25 Sep 2008 01:29:00 +0530

Want to try out a Linux distro but don't feel like switching from Windows, rebooting your computer, or installing a virtualization application like VirtualBox? MobaLiveCD is a Windows utility that lets you run any LiveCD in Windows without installing a thing. Just download and run MobaLiveCD.exe (which is a 1.4MB file), and select the ISO you want to run. Thanks to the magic of QEMU, you'll be able to run the Linux distro as a LiveCD in a window on your desktop. no reboot required.

Now, don't expect spectacular performance here. You're essentially running an operating system inside of another operating system, so things might be on the slow side. And it won't necessarily work with every host machine or every LiveCD. But at 1.4MB and with no installation needed, why not give it a try?

MobaLiveCD can also be installed to your hard drive, allowing you to launch LiveCDs via a right-click context menu. And you can create virtual hard drives to save data from your LiveCD sessions.

How to Install Squid Proxy Server

noreply@blogger.com (deepak) — Sun, 24 Aug 2008 22:10:00 +0530

How to Install Squid Proxy Server

Certainly Squid server is a favourite open source GPLd proxy and web cache. It’s a variety of functions, from accelerating a web server by caching repeated requests, to caching web, name server query , and other network lookups for a group of people sharing network resources. It is mainly designed to run on Linux / Unix-like systems. Squid is a high-performance proxy caching server for Web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven technique. Squid maintains meta data and specially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests. Squid comprises of a main server program squid, a Domain Name System lookup program (dnsserver), a program for retrieving FTP data (ftpget), and a lot of management and client tools.

Here is the instruction on how to install Squid proxy server:

1. Download Squid Cache

You can download Squid at http://www.squid-cache.org/Versions/ . There, you can see a lot of version of Squid. I prefer you to download the latest version. Here is the link for the latest version:

http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE8.tar.gz

Note: If you want to download it directly from your server. Please use the following command:

wget http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE8.tar.gz

2. Squid Cache Installation

To extract the downloaded compressed file, please use the following command:

tar -zxvf squid-3.0.STABLE8.tar.gz

this will create a directory named squid-3.0.STABLE8 at the current directory. Next, go into the directory:

cd squid-3.0.STABLE8

To build and install the Squid Cache, type:

./configure --prefix=/usr/local/squid
make all
make install

The command above will install squid in directory /usr/local/squid

3. Customize and Run Squid Cache

1. customize the squid.conf configuration file:
vi /usr/local/squid/etc/squid.conf

2. Initalise the cache:
/usr/local/squid/sbin/squid -z

3. start the cache:
/usr/local/squid/sbin/squid

Note: If you have problem to initialize the cache, please give the write permission (preferably chmod 777) for the specified directory.

Verify Squid Cache Installation

netstat -tulpn | grep 3128

Output:

tcp 0 0 0.0.0.0:3128 0.0.0.0:*

If you get the output above, you have successfully install Squid proxy server. :)

4. Client Configuration

Open a web browser > Tools > Internet option > Network settings > and setup Squid server IP address and port # 3128.

Good Luck!

Using TAR with Bunzip2 files

noreply@blogger.com (deepak) — Tue, 15 Jul 2008 14:25:00 +0530

Bunzipping and then unTARring in two steps is not convenient.

It is not necessary to use Bunzip2 and then TAR to unzip a file in two separate steps.

Tar will do the job on its own if the -j switch is used, thus:

tar xjvf linux-source.tar.bz2

By the same token, you may use the -z switch with a gzipped file, e.g.

tar zxvf linux-source.tar.gz

Enjoy!

All in one driver solution with DriverMax

noreply@blogger.com (deepak) — Wed, 9 Jul 2008 10:31:00 +0530

Need to reinstall Windows but you misplaced your driver disks? Not sure you have everything you need? DriverMax has you covered. Backing up and reinstalling your drivers couldn't be easier.

After installing DriverMax, go into Driver Operations and click on Export drivers. A list of all your installed drivers will be displayed and you can pick and choose which ones to export, or simply export the whole lot in one go. Once you've reinstalled Windows, go back into Driver Operations, click on Import drivers, and point to the folder containing your saved drivers. The import can take a while, but in comparison to manually installing each driver individually, this is a walk in the park.

DriverMax is also useful even if you don't need to perform a complete reinstall - you can use the program just to make sure that your drivers are up to date or export a list of your installed drivers as an html or text file.

DriverMax is compatible with Windows 2003, XP and Vista and you have to supply your email address in order to receive a registration code.

How to Configure Samba on RedHat Linux

noreply@blogger.com (deepak) — Wed, 25 Jun 2008 17:53:00 +0530

What's Samba?

Samba allows linux computers to share files and printers across a network connection. By using its SMB protocol, your linux box can appear in Windows Network Neighborhood or My Network Places just like any other windows machine. You can share files this way, as well as printers. By using samba on my home network, for example, my Windows machines have access to a printer directly hooked up to my Linux box, and my Linux box has access to a printer directly hooked up to one of my Windows machines. In addition, everyone can access everyone else's shared files. You can see how samba can be very useful if you have a network of both Windows as well as Linux machines.

Samba configurations are slightly different depending on the distribution you're using. Therefore, this tutorial explains how it's done on a RedHat Linux machine, as this is my distro of choice, and the only one I've ever installed samba on. The following method has been used by me on RedHat 7.2, 7.3, and 8.

Installing Samba

The first step to configuring samba is, obviously, to make sure that it's installed. In most cases, this will already be the case. It is often a good idea to install the samba daemon package with the RedHat installation.

You can test to see if samba is installed by typing rpm -q samba in a terminal. This performs a query on the samba package. If installed, it will indicate the version. If not, it will indicate "package not installed".

If samba is not currently installed, there are a multitude of places to get it. The RPM package is available on the RedHat CDs, on the RedHat network, or straight from www.samba.org or one of the samba mirror sites. In addition, you might wish to find it at www.rpmfind.net, a nice resource for RPM packages.

Once you have the samba RPM package downloaded somewhere on your harddrive, it's time to install it. Browse to where the file is located and perform one of the following two operations:

if samba is not currently installed,
rpm -i samba.rpm
(replace samba.rpm with the full version name of the file)

if you wish to upgrade your samba version,
rpm -U samba.rpm

Now that samba is installed, we can work on configuring this program.

smb.conf file

All of samba is configured in one single file, the smb.conf file. This file, located at /etc/samba/smb.conf, allows you to specify which resources on the linux machine you wish to share and who they can be accessed by.

A fresh installation of samba will include a sample smb.conf file. This file is completely commented, pointing out all of your available options, and how you can change them. However, samba is an extremely powerful tool, and most casual users have no need for 3/4 of the contents of this sample file. Therefore, I'm providing my own smb.conf file below. If you wish to just share a few folders across a small home LAN, you might be better off basing your own smb.conf file off of mine, as opposed to the long-winded sample file.

[global]
workgroup = PUTIEVILLE
server string = My Lil Linux Box
hosts allow = 192.168. 127.
log file = /var/log/samba/%m.log
security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

[Downloads]
comment = Downloads
path = /home/windisk/Downloads
browseable = yes
writable = yes
public = yes
read only = no

[homes]
comment = My Home Directory
browseable = yes
writable = yes
public = yes
read only = no

[printers]
path = /var/spool/samba
public = yes
guest ok = yes
printable = yes
browseable = yes
writable = yes
read only = no

Samba Users

Since we're using user level security (the best option when connecting to a WinNT based machine, such as Windows 2000 or Windows XP), we need to set up samba users.

First, lets create the smbpasswd file that we defined in the smb.conf file. The best way to go about this is to create it based on your existing /etc/passwd file. In other words, samba users are created based on existing linux users:

cat /etc/passwd | mksmbpasswd.sh > /etc/samba/smbpasswd

Chmod 600 this file (/etc/samba/smbpasswd) so that only root has read and write permissions.

However, this file only copies over Linux users to samba users. It doesn't copy over their passwords, as well. Therefore, use the following command to set each samba user's password:

smbpasswd username

Obviously, replace username with each of your user's usernames. You will then be prompted to enter a password for this user account. I like to set my samba user's passwords the same as their linux user counterparts. However, this isn't necessary.

Samba Service

Now that everything has been configured, the final step is to start the samba service. Samba runs in the background as a linux daemon. Therefore, it can be controlled by typing:

service smb start
service smb stop
service smb restart

Note that once the computer is restarted or shutdown, the samba service won't start up again the next time. I use the GUI (xwindows) program serviceconf to set up all my services to execute automatically.

Connecting To A Samba Resource

Now that everything should be working, let's test it out. We use the samba client to connect to a samba resource. For testing purposes, we can connect to localhost.

smbclient //localhost/Downloads

You must specify the name of the computer as well as the resource you wish to connect to. In this case, I can connect to the Downloads resource because I specified this resource in my smb.conf file (note it points to /home/windisk/Downloads).

Since you are using the samba client while already logged in as a linux user, you will only be prompted for a password. The username will be assumed to be the samba counterpart of the linux username you're currently logged in as.

If you wish, you can go to a Windows machine such as Windows XP. If you open My Network Places, and browse to your workgroup, your linux machine should be listed. When trying to access it, you should be prompted with a username and password. This can be any of the samba users you previously created. Once logged in, you should see a listing of all available resources available.
