[ILUG] Strange Network Problem

[Robert Synnott]

I'm having a strange network problem since I updated my distribution
(to Mandrake 10.1 x86_64). Most applications (Mozilla, Firefox, all
KDE applications) seem to be able to access the internet fine, but
console applications, and a few graphical applications (gaim) can't;
they seem to take about a minute to resolve the host-name. I have IPV6
off. Any ideas?
