(RADIATOR) Packet of Disconnect

Sun May 11 23:25:01 CDT 2003
We have read through the mailing list and
nobody has got it working successfully.
We setup the cisco server to accept POD.
aaa pod server auth-type any server-key xxxx
This will allow us to disconnect the user with any value
of the following
(username,framed-ip-address,Session Key or Session ID)
Unfortunately when we send the session it complains about an
invalid authenticator. We have found someone on the
freeradius mailing list how makes the following comment.
Many thanks for your reply. Just for your info we managed to get it
sorted out if it is still of use to you. The problem with the illegal
authenticator is that the authenticator on a auth request type packet
is calculated differently from the authenticator on a accounting
request (which POD is). My understanding is that the auth packet uses
the user-password as well as the secret key to calculate the
authenticator, where the accounting packet just gets an overall hash
from all the components of the packet. The detail is in the relevant
RADIUS RFCs and more specifically in the draft extension for packet of
disconnect (the later versions, I think no 6 or 7 is available).
We are using freeradius, and the radclient packaged with that works
well for bog standard auth and acct requests, but defaults to an auth
request for non-standard RADIUS request types (e.g. 40, POD). We
modified the radclient (and radiusd) code so that if we entered
radclient -f file -x <NASIP>:1700 40 (this is usually auth/acct)
It would calculate the authenticator as if for an accounting packet,
and Bob's your autnie, it works.
packet types returned, 41 for ACK (success), 42 for NACK (failure)
even though freeradius does not recognise these types it still gets a

Unfortunately even with this information we are unable to get it to work
maybe you could shed some light on this problem

Hello Michael -
You need to specify "Disconnect-Request" when you run radpwtst:
perl radpwtst -noacct -code Disconnect-Request .....
This is not an accounting request.
You will need to check with your NAS vendor what attributes need to be
This topic has been discussed on the mailing list previously:
