Internet connection problem under Mandrake 9.1

Hey there,

I recently installed a network card in my computer to use under my
windows boot, playing a few games and whotnot, however since then I
also reinstalled mandrake on my linux partition and it broke my
internet.

As far as I can tell, it still connects to the net properly (using
kppp) however when I boot up any internet programs, such as firebird
or pan, they can't find a host to the server. My best guess is that
they are trying to access the internet connection over the network
card, where it doesn't exist, rather than via my modem connection.

I've tried everything to fix this, mandrake network settings even asks
where your net connection is (modem or network) but nothing I do makes
any difference. I'm heading off to download debian over the next week
or so to try a new distro, but I was wondering if anyone here had any
ideas.

Usually caused by /etc/resolv.conf not having the dns nameservers.
That is if you can ping your ISP's gateway. If ping fails your default
route is dinked up. That maybe because of something added to
/etc/sysconfig/network

I have a nic to a cable modem. When I had to dial into work I had a script
which did the following:

/sbin/route del default # remove cable routing
/bin/cp -f /etc/hosts_work /etc/hosts
/bin/cp -f /etc/resolv.conf_work /etc/resolv.conf

and I could then use kppp to make the dialup connection.

The hangup script did the reverse and brought up the nic's network.
/bin/cp -f /etc/resolv.conf_home /etc/resolv.conf
/bin/cp -f /etc/hosts_home /etc/hosts
service network restart

Thanks for the info, i'll reboot and go check that out in a minute.

By the way, i've been using linux for a long time now and love it to
death, but I still dont understand it the way I do windows. Do you
know anywhere on the net I can find information about this sort of
thing?

I mean, I can run a desktop fine, but when It comes to things like
knowing which conf files are used where and how hosts files work, I
havn't a clue what exists and what doesn't.
