radclient: received response to request we did not send.

[Juan Nin]

Hi,

I'm trying to use radclient in order to disconnect users, with the
following PHP script:

<?
$framed_ip = 'xxx.xxx.xxx.xxx';
$cisco_ip='aaa.aaa.aaa.aaa';

popen("/bin/echo 'Framed-IP-Address=$framed_ip' |
/home/radius/bin/radclient -d /home/radius/etc/raddb/ -x $cisco_ip
disconnect secret", 'w');
?>

But I receive the error:

Sending Disconnect-Request of id 3 to aaa.aaa.aaa.aaa:1700
        Framed-IP-Address = xxx.xxx.xxx.xxx
rad_recv: Disconnect-NAK packet from host aaa.aaa.aaa.aaa:1645, id=3, length=20
radclient: received response to request we did not send.


This is the tcpdump (where bbb.bbb.bbb.bbb is the IP address of the
server where I'm running the script from):

21:07:59.171286 IP bbb.bbb.bbb.bbb.40122 > aaa.aaa.aaa.aaa.1700: UDP, length 26
21:07:59.315031 IP aaa.aaa.aaa.aaa.datametrics >
bbb.bbb.bbb.bbb.40122: RADIUS, Unknown Command (42), id: 0x03 length:
20


On my Cisco AS5300 I've added:

aaa pod server auth-type any server-key secret


What can be the problem??

Thanks in advance,

Juan
