[Asterisk-Users] Warm standby boxes - keeping config syncronised?

[Ed Greenberg]

How about using rsync on a cron timer to copy the config directory from the 
primary to the secondary.  You could have them sync every five minutes if 
you liked.

Also, plug the nic into the secondary (with the same IP address) but just 
don't autostart the interface. If the first box goes down, your monitoring 
box can connect to the management interface on the second box and bring up 
the traffic interface (and anything else that needs bringing up, like maybe 
Asterisk :)
