Hi people,

I am having a weird problem. I have a dual boot computer. Windows xp and ubuntu are installed. I have static ip address and also mac filtering on my network. on xp, internet works just fine. on Ubuntu, internet doesn't work even i did the same settings as i did on windows xp. then I wanted to try ubuntu live cd. I booted from live cd, i set up my ip address, dns servers, gateway and stuff, and internet worked!! but then again I did the SAME THING on installed ubuntu, it didn't work! it's really weird. I have CNET PRO200 ethernet card.

then I installed Fedora core 6 but it didnt work either. I installed before redhat 8, it just worked fine but I don't know why new releases don't work.

does anyone have a idea about this? what's the problem?

thanks for your help..

i can send configuration files if it would help to solve the problem.

Try the following two commands

If the second works and the first doesn't, you have a DNS problem. If they both fail and you have other machines on your network, see if you can ping them by address (numbers). If they both work, you'll have to dig a little deeper.

The LIVE CD-ROM's configure the Network for YOU automagically. The install-to-hard drive CD-ROM's need to be manually configured sometimes. Go to the menu select Network. Click through until YOU have a program to answer questions in. After settings are configured {YOUR username, password, ISP name, DNS Primary Server and Secondary Server, Gateway}. If YOUR ISP did not give YOU a hostname, leave blank. (Don't invent one to fill the space). When asked: start services at Boot?...answer YES. Save and exit. Reboot and press DEL or the <key>for YOUR BIOS. Change the startup for Hard Drive: First Boot Device. Because the CD-ROM Device was used for install of Distro as First Boot Device. Save and exit BIOS. Should boot into the System now.
