I log on to the Usenet with both XP and with Ubuntu 7.10 - Gutsy
Gibbon. I am a complete dunce at Linux, but Pan is working great for
me.

If you connect to the Web, I would suspect that the username and
password and/or the server name would bear close scrutiny. I use
Usenetserver and it is very unforgiving if I don't have the logon
script just right.
