Theres an url explaining that somewhere... but the problem is that this kind
of solution is not bulletproof.. imagine that for some reason the kernel panics
with an harddisk failure.. sometimes when this happens the machine still
replies to pings, squid is up and running, but obviously doesnt replies to
requests.. so you could grab the ip address because the other machine is still
using it... or is there any way around this problem?
