radius accounting - problem with prepaid users

We have some users who use prepaid cards in order to connect to our access servers.

This means that when they connect, a start record is stored in our database and when they
disconnect, a stop record is stored. The time between these 2 records is subtructed from
the card's total time, so the next time the user connects, the card starts with less time.

The problem is when the access server is powered off, so there is no stop record sent.

One solution would be to send accounting updates every x mins, but we don't want that for
all our dialup users. Is there a way we can configure it per-user (through aaa)?

Any other idea on how we can solve such a problem?

Anatassios,

An account record can be sent when the system is restarted.
This record should be used to indicate that all "OPEN".
(ie STARTs with no stop RECORDS) should be closed for that
NAS IP address.

This is successfully used at other SP.

You can try enabling periodic accounting on a per-user basis:

Cisco-AVPair = "lcp:acct-interval=<n>"

or

Acct-Interim-Interval = <n>

The latter attribute is defined in RFC2869.

You could also clear all users off a NAS before you reload or power it
off. If you configure system accounting, the NAS will also send an
Accounting-Off record to the RADIUS server when you reload the
box. This indicates to the server that all open accounting sessions on
that NAS should be closed. An Accounting-On record is also sent when
the NAS boots up so that the RADIUS server can close all open sessions
on the NAS if the Accounting-Off was never sent (like if the NAS was
powered off or crashed).

Assuming a user record in the users file similar like this:

test Auth-Type = Local, Password = "test"
Service-Type = Framed-User,
Cisco-AVPair = "ip:dns-servers=x.x.x.x x.x.x.x",
Framed-Protocol = PPP,
Framed-Route = "x.x.x.x/xx xx.x.x.x 1",
Framed-IP-Address = x.x.x.x,
Framed-IP-Netmask = 255.255.255.255

Add for your prepaid users simply following line

Acct-Interim-Interval = 300,

This will tell the cisco to send every 5min a Alive record for this user.

hth,
Eric
