Honestly, it's been a while since I've had a need for this. When I used this, I did it with asterisk. It was ugly, but very functional. The daemon runs basically as a single command. All options can be specified on the command line. Then you specific an up and a down script.<div>
<br></div><div>In my configuration, each server had it's own IP. The ip and down script would manage the passage of a virtual IP. The daemon used a cryptographic heartbeat and an elections process to decide who was up and who was not (allowing you to specify that sever A is always ACTIVE as long as it's available) OR you can specify a non-revertive configuration where if Server B becomes active because A is down, A will not become active again unless B goes down. I used rsync+cron to manage the configuration and database tree and the script would reload everything upon a configuration change. </div>

Can you tell us a bit more about your experience of this? In<br>
production? Requirements on LAN? Happy?<br>
<br>
Thanks!<br>
