Hi a am a newbie for Ubuntu .....and i m very desperate to learn it completely....can anyone please tell me
what i have to do while setting up network in it..
I had seen some settings like
Adding up a wired network and the adding some values of
dns server:
dhcp addresss
etc...
but dont know what they are... how to find then..
I am able to find them via windows....
As i m using Windows Xp right now

Welcome to LQ.
The network settings are similar to windows. DNS and DHCP server here mean the same no matter what platform you use.
DNS is a domain naming system which will resolve your domain name to its valid IP address like www.google.com to 209.85.175.99.
A DHCP is dynamic host configuration protocol where server can provide client with network information like IP address.
Now if you can tell us what kind of configuration you have in windows, it would be easy to do the same in Ubuntu which is pretty easy.
To see if your wired network interface has been properly diagnosed use the command
and paste the output in Code tags.
Also give the output of
in code tags.

Is your Windows system plugged into a router? Does it "just work"? Routers have built in DHCP servers within them so provided your Linux system is set up for DHCP, Normally he default, the router will assign an IP address to it just as it does with Windows and it'll "just work" as well. Most systems, Windows, MacOS, Linux, etc are defaulted to DHCP as it's just plug in and go. Unless you've some specific need to set up static IP addressing you shouldn't have a problem.

Play Bonny!

Usually, Ubuntu (and most other distros) should spot your network when you install. A possible problem is that you might have a modem rather than a router. What does it plug into on your computer? If it connects to the ethernet port, it's a router; if it connects to a usb port it isn't.

Just click the network icon and choose "Edit Connections"

Don't you think that that conflicts with the below requirement? And it will not work on the server edition
