Hi,
Linux-HA is one solution, as has been suggested; another, much easier to set
up, is UCARP -- http://www.ucarp.org/. It handles your virtual IP and the ARP
caching issues associated with it (by means of a GARP packet). I had a good
experience with it.

Subject: High availability virtual ip
i have two linux machines, that are running on the same LAN.
i would like to find a way to set HA IP.
i was thinking on creating virtual ip that will ride on the exiting eth. lets
say 10.0.0.1 and 10.0.0.2 and the VIP will be 172.16.4.1
both will run an infinite loop of:while (ping 172.16.4.1) do ...
once that the while is exiting in one of the hosts it will try to acquire the
VIP.
there is additional lock mechanism to implement so the two servers will not try
to acquire the same VIP concurrently.
i would like to know if there is any out of the box sofware that can do this
task?
