On our eduroam FR proxy, we had a home_server in a dead state for several hours. All status-server requests sent seemed to go unanswered.
That's usually an issue on the other end. But it's possible that FreeRADIUS got stuck.
During this period, I checked this home_server status with radtest : got answers !
I tried to get this host alive by radmin: it fell back to zombie and dead states again.
Hm... is it using the same source IP as radclient?
The only solution found to revive this home_server : restart the FR process on our proxy and the home_server remain to alive state.
So, here are my questions :
- Why the status-server requests sent by FR in dead state did not get answered, while those sent by radtest get response ?
It's not clear.
- Is there a way to force a revive from a dead state even with unanswered status-server requests ?
You can keep reviving it, but the server will keep marking it dead, if the home server doesn't respond. Try upgrading to 3.0.21. Maybe that helps. Alan DeKok.
