See if you can access yahoo.com using
http://216.109.118.71

If you can you probably need to add your ISP's DNS server in /etc/resolv.conf
it goes something like this:

nameserver <ip address>

or alternatively just setup a cache only bind server then point it to yourself.

Are you using a dynamic IP? If yes, your /etc/resolv.conf should have been created dynamically by dhclient .. otherwise (static IP), you need to add your ISP's dns server to /etc/resolv.conf. If you're following a HOW-TO to setup your adsl connection, take a look at it DNS section.

yes my isps dns is in there as well as the alternate. i was messing around with dns yesterday to get my website to respond to a dns instead of a horrible http://xxx.xxx.xxx.xxx. is there any thing i may have changed that i might have forgot to change back, as far as i am aware i changed every thing back to what it was after i changed it. i have only had linux since friday and have never used it befor that i am a real newb but am picking it up fast.

thanks mike
