[magmike at mail.ru]

Hello,

today my radius reveived very strange packet from pppd.

Acct-Output-Octets was not number!
accounting-Stop packet looks like follow:

Wed Apr 12 04:27:39 2006
    Acct-Session-Id = "443B9E03290F"
    User-Name = "user_name"
    Acct-Status-Type = Stop
    Service-Type = Framed-User
    Framed-Protocol = PPP
    Acct-Authentic = RADIUS
    Connect-Info = "10511"
    Acct-Session-Time = 36700
    Acct-Output-Octets = Route-Appletalk-No
    Acct-Input-Octets = 42725588
    Acct-Output-Packets = 539724
    Acct-Input-Packets = 607374
    Calling-Station-Id = "192.168.1.33"
    NAS-Port-Type = Async
    Framed-IP-Address = 10.0.0.9
    NAS-IP-Address = 192.168.0.41
    NAS-Port = 292
    Acct-Delay-Time = 0
    Client-IP-Address = 192.168.0.71
    Timestamp = 1144794459

All previous "Interim-Update" packets for this sessions
was right except last and "Stop" packets:

Wed Apr 12 04:19:32 2006
        Acct-Status-Type = Interim-Update
        Acct-Output-Octets = 74708441
Wed Apr 12 04:23:32 2006
        Acct-Status-Type = Interim-Update
        Acct-Output-Octets = 74745120
Wed Apr 12 04:27:32 2006
        Acct-Status-Type = Interim-Update
        Acct-Output-Octets = Route-Appletalk-No
Wed Apr 12 04:27:39 2006
        Acct-Status-Type = Stop
        Acct-Output-Octets = Route-Appletalk-No
