Mike,

We're using MAXen (via an external provider), and I see stop records
without a user-name whenever the max answers a call but fails to
negotiate any authentication. Many NAS' would not record any
start or stop until a session was authenticated, but we seem to get a
'stop' (only) with no user-name for any failed called - its handy
because you can see the failure reason (chap failed, ppp negotiation
failed, etc.).

(It doesn't cause us too many difficulties, but then wedon't have an
external session database, and we post-process the detail
for accounting purposes, so we just drop the 'no-name' records.)


Here's a sample:

Mon Mar 15 22:27:10 1999
        NAS-IP-Address = XXX.XXX.X.X
        NAS-Port = 1038
        Called-Station-Id = "9999"
        Calling-Station-Id = "299XXXXXX"
        Acct-Status-Type = Stop
        NAS-Port-Type = Async
        Ascend-Disconnect-Cause = noModemLossCarrier
        Ascend-Data-Rate = 0
        Ascend-Billing-Number = "N1"
        Acct-Session-Id = "A0E310216BC0"
        Timestamp = 921497230

Looking at your example you gave, given the low bytes in/out and the
short session time,
it seems likely that this is what you're seeing...
