Brendan,

You have not given much info in your posts (hence the stony silence :), so
I'm going to read between the lines a little.

I'm guessing you have the two network cards configured on the same
network, because you talk about redundancy and possibly using the same IP
for both cards.  I think this is where your problem lies.

Unless you use some specialised software and a switch that supports it,
you cannot have both cards on the same IP address (AFAIK!).  Furthermore,
having them both on the same network subnet will lead to problems with
routing of outbound traffic from the box.

For the moment I think you will have to keep one card off until someone
wiser than me can suggest software which will enable what you are after.

The manual alternative is to write a script to configure and "up" the
second interface if the first should die.  You could even add a status
check (ping another IP on the subnet that should always be up), and let
this run every minute in cron to "automate" the changeover.  It's crude
but might help you in the mean time.

Regards,
Patrick O'Reilly.
