mysql> select count(*) from radacct where username ='absolute' AND
acctstoptime=0;

If I look at my /var/log/radius I can see:

Tue Jan 22 08:51:06 2008
        User-Name = "absolute"
        Acct-Status-Type = Stop
        Acct-Session-Id = "00:0E:0C:2D:18:56:120099420910511"
        Acct-Authentic = RADIUS
        Acct-Session-Time = 35
        NAS-Identifier = "#######"
        NAS-IP-Address = ###.###.###.###
        Acct-Input-Octets = 273675
        Acct-Output-Octets = 128263
        Acct-Input-Packets = 961
        Acct-Output-Packets = 1002
        Calling-Station-Id = "00:1e:4c:13:c1:37"
        Called-Station-Id = "00:0E:0C:2D:18:56"
        Framed-IP-Address = ###.###.###.###
        NAS-Port-Type = Wireless-802.11
        Class = 0x20
        Acct-Terminate-Cause = Admin-Reset
        Acct-Unique-Session-Id = "5e5fbec08c10c41f"
        Timestamp = 1201020666
        Request-Authenticator = Verified

So, the session has been terminated as you can see by the last record in
the first query, but the query with the full where clause picks up on
the old accounting record. Using acctstoptime IS NULL has the same
result. 'datefield = 0' seems to match on datetime fields on my version
of Mysql. (In schema 1.5 acctstoptime datetime NOT NULL default
'0000-00-00 00:00:00'). From what I can see start, interim and stop
records are being recorded just fine. The issue is that the sql queries
are matching old accounting records. Any idea on how I can fix this
issue? If there is something I'm not understanding, please let me know.

At this point I think my next step might be to update to the new version
of freeradius, with the full 2.0 schema. Any other suggestions?

Thanks very much for the reply,

Dryw Paulic

Don't do this.  The operator is incorrect as is nearly every use of
Auth-Type.

What is shown when you use the full where clause from the previous
command?  
What version of MySQL are you using?  I just tried this with 5.0.48 and
'datefield = 0' does not match on datetime fields.

If you're using the V2.0.0 schema, that SQL query should be changed to
'acctstoptime IS NULL'.  Try this from your SQL command line and see if
it gives the desired results for both connected and disconnected users.
