usr-hiper and freeradius 2.1.5 accounting problem

[haries fajar nugroho]

Hi All,

I wanna migrate my radius server from icradius to freeradius 2.1.5. i
have two ras modem for my nas (patton and usr-hiper).
When I do some migration simulation, client that connect from patton
goes normally (authentication,accounting,authorization).
But when they use usr-hiper (system version :V5.1.6/Non-Encr), the
client could connect to the network but the accounting goes wrong.

In my freeradius debugging mode, the error message was :
rad_recv: Accounting-Request packet from host x.x.x.x (* encrypted ip)
port 1646, id=63, length=405
Received Accounting-Request packet from x.x.x.x (* encrypted ip) with
invalid signature!  (Shared secret is incorrect.) Dropping packet
without response.
Going to the next request
Waking up in 0.9 seconds.

The usr-hiper accounting settings :

HiPer>> sh accounting

What I have tried to solve it :
1. I've tried to make multi port for accounting packet (1646 & 1648),
because i thought that the error message refer to wrong accounting
port.
But the accounting still wrong.

2. I've tried to use default freeradius secret at the freeradius side
with testing123 without changing the secret at the ras modem. But
still failed.


Do you have another solution ?

Thanks before :)
