IP address conflict handling
Hi all,
I'm tring to make an automatic fail-over setup with two machines, and my idea so far if to have both machine attempt to get the same IP on start-up, and if they fail, to change thier IP to the stand-by machine and serve as the back up. It will monitor the primary, and if it disappears for a certain length of time (10mins i'm thinking) it re-takes the IP and does it's stuff. So the question is, what happens on start-up when a machine attempts to aquire an IP address that has already been taken. What do I look for? My guess is that the address goes to 0.0.0.0, but is there a specific error which thrown up? Many thanks, Paul. |
You might want to look at some of the links on http://www.tldp.org/HOWTO/Adv-Routin...rtc.other.html especially the Virtual Router Redundancy Protocol and the Linux Virtual Server project.
