Configure 2 network cards

[Tobias Speckbacher]

A great situation to make use of bonding !
Check out /usr/src/linux-2.4/Documentation/networking/bonding.txt, it
has all the information you need to get it set up and even describes
different scenarios.

Some of these require switch configuration.

All in all its very trivial to get going with.

Good luck,

Tobias

If you want both cards to use the same network configuration, I think 
you'll want to use VRRP.   I haven't tried the following, but here is a 
userland implementation of VRRP:

And this page from the Linux Advanced Routing and Traffic Control HOWTO 
describes a simple config with vrrpd:
