Help with syncing config between 2 pound servers

Hey all

we are trying to set up 2 pound servers in a master-slave/passive/failover config for high availability. All the documentation I've found online refer to a single pound server except for this link which shows how to configure keepalived to do this.

But what is not clear is how to keep the pound.cfg files on each box in sync as our network team make changes.

I've tried this with a cronjob to rsync the file over and to then do a force-reload pound but it keeps crapping out. I've setup ssh keys on each one and added the user to sudoers so permissions look ok. Another issue is that cron only syncs a minimum of 1 minute interval and network team are looking at 5-10 second intervals if possible.

Anyone have suggestions on how best to achieve this?

I've seen unison mentioned on a couple of posts, is that worth investigating?

Cheers, Kiweegie
