Accounting-Response with invalid signature

[Rio Yang]

Hi All,

I got the following message from my radius.log.

Wed May 23 16:39:11 2007 : Error: Received Accounting-Response packet from
172.16.1.1:1813 with invalid signature (err=2)!  (Shared secret is
incorrect.)
Wed May 23 16:39:11 2007 : Error: Reply from home server 172.16.1.1:1813  -
ID: 180 arrived too late for request 2515449. Try increasing 'retry_delay'
or 'max_request_time'

It caused some problem on accounting record .

The secret between NAS and RADIUS are the same.
But the log tell me the secret is incorrect at Accounting-Response.

Do anybody know what's the main cause and how to fix it ?

PS. NAS and Radius are in the same subnet without any firewall.

Rio at TW
