(RADIATOR) Stopping processing on Invalid radius requests

[Martin Edge]

Hey Guys,
 
Is there a way to stop processing some radius packets depending on
information?
 
Like, for instance.. the radius stop record below is sent via a USR Nas
who hasn't been able to authenticate a user, but it still sends the
stop/start record because of the connection itself. There are other
Ascend NAS's that react the same way for us.
 
If I can possibly build a hook to just say drop this request, then I
would save filling up logs with unnecessary SQL errors
(Framed-IP-Address is required in all SQL entries, and where they aren't
allocated one..)
 
I'm not sure the syntax required in the hooks to say "ACCEPT" or
"REJECT" user, or to just say "stop processing"
 
        User-Name = "unauthenticated"
        NAS-IP-Address = 202.160.140.3
        Acct-Status-Type = Stop
        Acct-Session-Id = "51576937"
        Acct-Delay-Time = 0
        Service-Type = Framed-User
        NAS-Port-Type = Async
        NAS-Port = 788
        USR-Interface-Index = 2044
        USR-Chassis-Call-Slot = 4
        USR-Chassis-Call-Span = 1
        USR-Chassis-Call-Channel = 20
        USR-Unauthenticated-Time = 2
        USR-Modem-Training-Time = 18
        Calling-Station-Id = "0298073422"
        Called-Station-Id = "0282053301"
        USR-Modulation-Type = v90Digital
        USR-Simplified-MNP-Levels = ccittV42
        USR-Simplified-V42bis-Usage = ccittV42bis
        USR-Connect-Speed = 44000_BPS
        Framed-Protocol = PPP
        Acct-Session-Time = 20
        Acct-Terminate-Cause = User-Request
        Disconnect-Reason = 8
        Acct-Input-Octets = 127
        Acct-Output-Octets = 215
        Acct-Input-Packets = 5
        Acct-Output-Packets = 7
        Call-Arrived-time = 183605368
        Call-Lost-time = 183605388
 
Thanks,
Martin
