Dual ethernet ports, one IP address

On a Sun server I once worked on with we had two ethernet ports
connected to the HUB but only one IP address was used for both. If one
would fail, the other would take over on the same IP address. Is such
functionality available in Linux? If so, where can I find documentation
to set it up for Fedora with a 2.6 kernel?

Yes, you need to add the two interfaces to a bridge interface, then
assign the IP address to the bridge interface. That should give you enough
information to find the documentation.

It seems that the OP is looking for interface bonding,
not bridging.

Well, I'm looking for a failover mechanism where one ethernet interface
takes over from the other when it fails and continues with the same IP
address. Clustering, but then on the same Linux server.

Perhaps is it possible for you to write an script? I would think it is
possible for a script to check the network interface and if one fail,
automatically switch over to the other one?
