This problem has been extremely frustrating for me. I have a computer which is dual booting between linux and windows, and I used to have SuSE (6.2) but now have RedHat (7.0). One of the reasons I decided to try out RedHat was because I could never get the internet (I have a dial-up acount) working on SuSE. So when I installed RedHat, ran the Dial-up setup tool, and somehow was able to connect and everything worked perfectly.
However, a day later, I tried again to connect, and it hasn't worked since. I know my setup for dial-up is correct, because I did not change it, but I am having trouble initiating the connection. First I tried the RedHat PPP dialer. It will launch, I select the interface, and it gives me an error, saying it can't do it without even dialing. Next I tried wvdial, and it seemed to be working great, I could hear it dial, connect, and see that it had sent my user name and password, and that pppd had been started. However, when I opened up netscape, it spat at me that the server for the site I wanted to visit could not be found. I thought this might be a Netscape problem, because it looked to me like I was connected, so I tried Lynx, with the same results.
Because I can't acesss the internet from linux, I am being forced to spend much more time in Windows than I would like. Can someone please help me?

Assuming that you had actually connected then there could be a prob with your /etc/resolv.conf file? Did you set it in the first place? If so you should check it.

You were right, it works now and I am typing this from Linux (Aaaaahhhhh) thank you very much!
