Sorry, I don't understand that. Can you elaborate?

It sounds like you have a custom module, written locally?

Modules process packets. So you can't run module code in response to a 
"home server down" event (unless you emit a packet that your module 
responds to, I guess).

As I said, triggers are only available in the "master" git branch. They 
are not available in the releases code (2.1.x, 2.2.0).

You will need to compile and install "master" to get triggers.

Sorry, I don't understand why this is relevant.

See:

You'll still need to find out which server is down, and this is what 
"radmin" does. I wouldn't bother with this post-proxy stuff - just write 
a cron job (although maybe you could trigger the cron job from 
post-proxy, for fast detection).
