How to: Setup Flyback for backing up your data

noreply@blogger.com (skymack) — Thu, 10 Jul 2008 05:08:00 +0000

Intro: Most of people go to Apple's Time Machine for thier backup software. The software is a great feature in their OS, and Linux has almost all of the required technology already built in to recreate it. This is a simple GUI to make it easy to use. In Linux its call Flyback. Most of peoples also called "Time Machine for Linux".

Below is the way to install it on Ubuntu:

1. Install the dependencies first
# sudo apt-get install python python-glade2 python-gnome2 python-sqlite3 python-gconf rsync

2. Download the flyback software

# wget http://flyback.googlecode.com/files/flyback_0.4.0.tar.gz

3. Then change to the new directory ("flyback/src/" or "flyback/", depending on which you chose above) and run:

4. Run this command
# python flyback.py

5. Finish

Tips:
To install, don't login as root. You need to run as sudoer. The system won't install and run as root.

Some screenshot for the flyback software:

New Ubuntu 8.04 (Hardy Heron)

noreply@blogger.com (skymack) — Sun, 11 May 2008 04:28:00 +0000

This is the way I like with Ubuntu. Its a productive distro and the main reason is its user friendly Linux ever (Just my opinion). Last day, I just send email to all my staff. Oh God, they are reply my email with the good comments, even they ask me the CD (hahahaha...become supplier for my office).

Below is the good thing about latest Ubuntu 8.04:

1. The desktop CD allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later.

2. You will need at least 384MB of RAM to install from this CD.

3. Coming on 2 type: Desktop and Server

4. Holy shits...its can install on windows. See picture below. This is the screen shot when you put your CD on your CD drive.

5. New desktop appearance. (Nice desktop graphic)

Hopefully the Ubuntu can be the best distro/Linux flavor on the future.

sudo gedit /etc/apt/sources.list

4. Uncomment (or add) following lines:

deb http://us.archive.ubuntu.com/ubuntu gutsy universe

5. Add this line:

deb http://wine.budgetdedicated.com/apt gutsy main

6. Close gedit. Update and install wine and cabextract:

wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | sudo apt-key add -

How to : Play a real media file

noreply@blogger.com (skymack) — Sat, 08 Dec 2007 00:13:00 +0000

Hi, to play a real media file you need this component. I have tested it on Ubuntu 7.10 before. This is the easy way I do it:

1. Install the Kaffeine player. To install just go to 'Synaptic Package Manager' and search for it. Then, 'Mark for Installation' to install the Kaffeine.

2. You need download the "essential codecs package" from MPlayer download page: http://www.mplayerhq.hu

3. Make directory name "win32" in the /usr/lib with your terminal. Please doing this section with root privilage. Its become /usr/lib/win32 .

4. Extract the "essential codecs package" that you have download before and copy all the contents to /usr/lib/win32 .

5. Open Kaffeine player. For the 1st time the kaffeine can't play the real media. This is because the codec is not define properly. What you can do is, just go to settings --> xine engine --> parameters --> decoder and type /usr/lib/win32 under the external Real Media codecs path. Now you can enjoy watching your real media file. Thats all.

Another Ubuntu Flavor: Ubuntu Studio

noreply@blogger.com (skymack) — Fri, 03 Aug 2007 12:39:00 +0000

Ubuntu Studio bills itself as the "multimedia creation flavor of Ubuntu," an official Ubuntu project "aimed at the GNU/Linux audio, video, and graphic enthusiast as well as professional." It is certainly flashy on the outside -- even if it is mostly the same Ubuntu Linux distro under the hood.

"We provide a suite of the best open-source applications available for multimedia creation. Completely free to use, modify and redistribute. Your only limitation is your imagination."

For me, this Linux is nice for multimedia. Current release is UbuntuStudio 7.04. Congratulation to Ubuntu Team that make this distro (Ubuntu Flavor) alive!.

Linux Networking no.5: Round Robin DNS Load Balancing

noreply@blogger.com (skymack) — Fri, 13 Jul 2007 01:36:00 +0000

How DNS load balancing works
When the request comes to the DNS server to resolve the domain name, it gives out one of the several canonical names in a rotated order. This redirects the request to one of the several servers in a server group. Once the BIND feature of DNS resolves the domain to one of the servers, subsequent requests from the same client are sent to the same server.

DNS load balancing implementation (Multiple CNAMES)

This approach works for BIND 4 name servers, where multiple CNAMES are not considered as a configuration error. Assuming there are 4 web servers in the cluster configured with IP addresses 192.168.1.[1-4], add all of them to the DNS with Address records (A Names) as below. The server[1-4] can be set to any name you want, such as foo[1-4], but should match the next step.

server1 IN A 192.168.1.1
server2 IN A 192.168.1.2
server3 IN A 192.168.1.3
server4 IN A 192.168.1.4

Add the following canonical names to resolve www.yourdomain.com to one of these servers.

www IN CNAME server1.yourdomain.com.
IN CNAME server2.domain.com.
IN CNAME server3.domain.com.
IN CNAME server4.domain.com.

The DNS server will resolve the www.yourdomain.com to one of the listed servers in a rotated manner. That will spread the requests over the group of servers.

Note: The requests sent to http://yourdomain.com (without 'www') should be forwarded to http://www.yourdomain.com in this case to work. For BIND 8 name servers, the above approach will throw an error for multiple CNAMES. This can be avoided by an explicit multiple CNAME configuration option as shown below.

options {
multiple-cnames yes;
};

DNS load balancing implementation (Multiple A Records)

This above approach with multiple CNAMES for one domain name is not a valid DNS server configuration for BIND 9 and above. In this case, multiple A records are used.

www.foodmalaysia.net. 60 IN A 192.168.1.1
www.foodmalaysia.net. 60 IN A 192.168.1.2
www.foodmalaysia.net. 60 IN A 192.168.1.3
www.foodmalaysia.net. 60 IN A 192.168.1.4

The TTL value (eg: 60) should be kept to a low value, so that the DNS cache is refreshed faster.

Other considerations

The DNS based load balancing method shown above does not take care of various potential issues such as unavailable servers (if one server goes down), or DNS caching by other name servers. The DNS server does not have any knowledge of the server availability and will continue to point to an unavailable server. It can only differentiate by IP address, but not by server port. The IP address can also be cached by other nameservers, hence requests may not be sent to the load balancing DNS server.

Considering the functionality, the round robin DNS is not a load balancing mechanism but a load distribution option. Some of these drawbacks can be overcome by implementing an advanced version of the DNS load balancer using Perl scripts.

Some other variety of load balancing can be performed by using a proxy server, where one of the web servers, is solely used for re-routing of traffic to the other servers. If Apache is used as a web server, the mod_rewrite feature of Apache can be used for this purpose as detailed in this Apache website article.

Linux Networking no.4: Common Network Tools

noreply@blogger.com (skymack) — Fri, 06 Jul 2007 08:39:00 +0000

Here is a short list of tools helpful when trouble shouting network connections.

1. ping:

This tools sends and ICMP ECHO_REQUEST datagram to a host and expects an ICMP ECHO_RESPONSE.

Options for ping
-b ping a broadcast address
-c send N packets
-q quiet mode: Display only start and end messages

2. tcpdump:
This is a tool used to analyse network traffic by capturing network packets. The following commands illustrate some options:

Let tcpdump autodetect network interface
tcpdump

Specify a network interface to capture packets from
tcpdump -i wlan0 (wlan0 is your network interface card)

Give an expression to match
tcpdump host 192.168.10.1 and port 80

3. netstat
Get information on current network connections, the routing table or interface statistics depending on the options used.

Option for netstat:
-r same as /sbin/route
-l display list of interface
-n don't resolve IP address
-p returns the PID and names of programs (only for root)
-v verbose
-c continuous update

4. arp:

Display the kernel address resolution cache.

5. traceroute:

Displays the route taken from the local host to the distination host. Traceroute forces intermediate routers to send back error messages (ICMP TIME_EXCEEDED) by deliberately setting the ttl(time to live) value too low. After each TIME_EXCEEDED notification traceroute increment the ttl value, forcing the next packet to travel further, until it reaches its' destination.

Option for traceroute:

-f ttl change the initial time to live value to ttl instead of 1
-n do not resolve IP numbers
-v verbose
-w sec set the timeout on returned packet to sec

Thats all.

Linux Networking no.3: Stop and Start Networking

noreply@blogger.com (skymack) — Fri, 06 Jul 2007 08:16:00 +0000

Stop and start networking in Linux is quite defference with windows. Some peoples like to start and stop their networking with this command:

1. To start on Ubuntu Linux (network script):
/etc/init.d/networking start
2. To stop
/etc/init.d/networking stop

On Debian similar commands are used as above.

but

Do you know other command?
The others command is:

To start :
ifup eth0 (eth0 is your network card name)

To stop:
ifdown eth0

That all.

Linux Networking no.2 : DNS Resolve with Dig

noreply@blogger.com (skymack) — Mon, 02 Jul 2007 10:38:00 +0000

Using dig command on your terminal to resolve a domain.

1. Open terminal and type dig foodmalaysia.net. See picture below for sample result.
2. To check your local webserver is responsible for this domain, use the following command:
dig @localhost foodmalaysia.net

3. Use also this command to check your mailserver responsibelity
dig MX foodmalaysia.net

4. To get all available command, run this command:
dig --help

5. A more detailed and description, type this command for linux manpage:
man dig
To quit in this manpage, press button Q on your keyboard.

Linux Networking no.1: IP Address classes

noreply@blogger.com (skymack) — Mon, 02 Jul 2007 10:26:00 +0000

Internet protocol (IP) defines the structure of packet of data (datagrams) that are exchanged over the network.

IP address classes have a following range:

Class A: 0.0.0.0 to 127.255.255.255

Class B: 128.0.0.0 to 192.255.255.255

Class C: 192.0.0.0 to 223.255.255.255

Class D: 224.0.0.0 to 239.255.255.255

Class E: 240.0.0.0 to 247.255.255.255

Run ifconfig at your terminal to see you IP and refer back in this article for classes.
