database.
• Delay Time - The time delay (in seconds) since the AccountingRequest packet was sent and the
authentication acknowledgement was received. This can be subtracted from the time of arrival
on the server to find the approximate time of the event generating this AccountingRequest. Note
that this does not reflect network delays. The first attempt will have this parameter set to 0.
• Timestamp - The number of seconds since 1970-01-01. Used to set a timestamp when this
packet was sent from NetDefendOS.
STOP Message Parameters
Parameters included in STOP messages sent by NetDefendOS are:
• Type - Marks this accounting request as signaling the end of a session (STOP).
• ID - An identifier matching a previously sent AccountingRequest packet, with Acct-Status-Type
set to START.
• User Name - The user name of the authenticated user.
• NAS IP Address - The IP address of the D-Link Firewall.
• NAS Port - The port on the NAS on which the user was authenticated. (this is a physical port
and not a TCP or UDP port).
• User IP Address - The IP address of the authenticated user. This is sent only if specified on the
authentication server
• Input Bytes - The number of bytes received by the user. (*)
• Output Bytes - The number of bytes sent by the user. (*)
• Input Packets - The number of packets received by the user. (*)
• Output Packets - The number of packets sent by the user. (*)
• Session Time - The number of seconds this session lasted. (*)
• Termination Cause - The reason why the session was terminated.
• How Authenticated - How the user was authenticated. This is set to either RADIUS if the user
was authenticated via RADIUS, or LOCAL if the user was authenticated via a local user
database.
• Delay Time - See the above comment about this parameter.
• Timestamp - The number of seconds since 1970-01-01. Used to set a timestamp when this
packet was sent from the D-Link Firewall. In addition to this, two more attributes are possibly
sent:
• Input Gigawords - Indicates how many times the Input Bytes counter has wrapped. This is only
sent if Input Bytes has wrapped, and if the Input Bytes attribute is sent.
• Output Gigawords - Indicates how many times the Output Bytes counter has wrapped. This is
only sent if Output Bytes has wrapped, and if the Output Bytes attribute is sent.
Note
The (*) symbol in the above list indicates that the sending of the parameter is user
configurable.
