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

How to : Play a real media file

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

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

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.
