Empty (not ended) session - freeradius 3.0.16

[dg]

Hello,

i have another question about not ended sessions in FR (thanks Alan for last
replay).

What about situation when switch is suddenly down (for example power failure).
and empty sessions appears in database.

in this case NAS wont send stop packets (because of suddenly power failure).

Can i avoid this ? i mean empty session (with stop time -> NULL).
Is there any way that FR will check if NAS or end user is still alive ?


best regards

  The NAS isn't sending stop packets.  FreeRADIUS can only log what it gets.

  Fix the switches to send stop packets.
