I was using internet for some time , and went for a break , after that the internet isnt working in my Ubuntu
I try to ping , but showing unknown host , even though its working in WinXp .
I tried ifconfig then i realise that i'm not able to get DHCP IP .
Can anyone help me to get back my internet connection!!

Did you check you Network Connection tool? Also try pppoeconf

First thing to check is that it is not a name server issue. Can you ping an ip address (rather than hostname)? What is in /etc/resolv.conf?

Next just try to bring down the interface and then bring it back up again. eg

Code:

sudo ifdown eth0
sudo ifup eth0

Where I'm assuming that eth0 is the name of your interface.
