Really good stuff! I didn't know them. Thanks!

Interesting... I didn't know that. Thanks.

Or "ucarp". I guess "keepalived" has been mentioned already and since
you're not running a cluster it might be an overkill.

I have not used it, but you might want to look at the vrrpd package.

You seem to be looking for fail safe redundancy, may be you would like 
to check heartbeat, or running a small cluster with virtual servers in 
it, with fail over.


Sincerely,

Hi,

I have two servers A and B, where both knows the IP address of itself
and the other. Assume A goes down (that is, A is not reachable via
ping), then B temporarily takes the IP address of A via IP aliasing. Now
the problem is, when A wakes up, I want B to get alerted by this event.
Any ideas?


Best.
