[NTLUG:Discuss] Dual Nic's

[Paul Drew]

Howdy Guys,
I have a quick question I was hoping that I could get some information from 
you guys on. We currently have a Redhat proxy server running on a Penguin 
Computing 1U rack mount case. It is sitting RIGHT next to the networking 
switches. Recently the switch it was plugged into died, and so no one could 
get to the website, and made things messy around here.

What I am curious about is, dual ethernet cards. I was wondering what the 
possiblity of having both nic's plugged in and used. What I would like to do 
it have both ip's in the same subnet, and have DNS somehow failover to the 
other incase 1 went down. I thought it would be a nice way to at least take 
1 potential failure out of the loop. Having each nic go to a different 
switch.

Let me know if this is possible, or if its a no-brainer, or if I am smoking 
crack. To be honest I have not put much thought into it, but I wanted to run 
this by you guys to see if you are doing something of the sort already. 
Thanks for your time, and suggestions. Have a great day, and take care.
