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).

Can you please elaborate.I searched the file "trigger.conf" using "find
/ -name trigger.conf" but did not get anything.Do I need to create it by
my own.

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.

In the proxy.conf I have old style realm configuration.Ip's for
authorization and accounting hosts in the realm section.

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

    It's possible you could do something in the "post-proxy" section
    like so:

    post-proxy {
       Post-Proxy-Type Fail {
       }
    }

I was looking into default.original in sites-enabled for this.Can you
give me some examples for this ?

See:

https://github.com/alandekok/freeradius-server/blob/v2.1.x/raddb/sites-available/robust-proxy-accounting#L104

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).

Thanks a lot both Phil and Alan for your reply. Now let me put this requirement straight. I have freeradius server running on my system which takes request from NAS and send Access Request with PPAQ vsa for quota update to PPS. PPS replies back with Access-Accept with the updated quota.Now for error scenario's that PPS failed to respond,I have to handle this scenario for example writing a log or setting a flag.Now I was trying to download the master branch for triggers as you said but git is not installed in this system, I was also tried with radmin but this involves writing a cron. Now more specifically instead of server down I want to detect the scenario when PPS failed to respond as Alan suggested and I want to detect it in my rlm code.
