[SATLUG] Simple fail-over options

[Samuel Leon]

I need to get redundancy on a business webserver.  Not really sure how 
to go about this.  First I got to figure out the best way to keep the 2 
servers synced.  And then I was thinking about maybe writing a bash 
script on server#2 or something that would ping server#1 every minute or 
so.  Then if the ping times out, it will run another script to change 
its IP to server#1's IP.  Seems like it would work as long as server#1 
is truly down and doesn't come back to life and we end up with 2 of the 
same IP's on the same network.  Sound good or alittle too dirty?
