The working SER installation uses radiusclient-ng 0.5.0-1. It was compiled
after a CVS download maded on the beginning on jun/2005. Unfortunatly I miss
the source code and am using an i686-RPM derived from that code.

I already try to use this RPM (version 0.5.0-1) on the Xeon machine. The
results are the same. Just same message on /var/log/messages:

"Mar  2 21:45:54 sip openser: rc_check_reply: received invalid reply digest
from RADIUS server"
can you run the radius server in debug mode to see there what messages you get. Also, check the /var/log/syslog or /var/log/messages to see other error messages printed by radiusclient-ng library when you use debug mode with openser.

When I start "openser -TDdd I see:

I double checked all the "dictionary" definitions, triple checked my OpenSER
and Radiusclient-NG config and were not able to find the mistake.

So I'm really out of ideas... Maybe is the return value ("Authenticated")
illegal?

Hello,

the error:

Mar  1 15:41:43 dell openser-TEST[20789]: rc_check_reply: received invalid
reply digest from RADIUS server

comes from the radiusclient-ng library, in file "lib/sendserver.c" at
line 498. Did you use the same version of radiusclient-ng before?

Hi, Guys...

As the MySQL problem is aparently solved I’m facing a Radius issue… I'm

using FreeRadius 1.0.4, RadiusCliente-NG 0.5.2 and OpenSER 1.0.1.

If I duplicate the configs used with SER (and that it works fine) I’m

unable to authenticate my UA (the same that authenticate with SER). The
message with “debug=4” is:

Mar  1 15:41:43 dell openser-TEST[20789]: check_nonce(): comparing

[4405ec129258d5cf9c016ade69cf37e33b5af52b] and
[4405ec129258d5cf9c016ade69cf37e33b5af52b]

Mar  1 15:41:43 dell openser-TEST[20789]: rc_check_reply: received

invalid reply digest from RADIUS server

Mar  1 15:41:43 dell openser-TEST[20789]:

ERROR:auth_radius:radius_authorize_sterman: rc_auth failed

So I supposed that there were some failed configuration, I looked at my

“radiusd.conf” and finded:

  modules {
  ...
    digest {
    }
  ...
  }
  authorize {
          preprocess
          auth_log
          suffix
          digest
          sql
  }
  authenticate {
          digest
  }

As my FreeRadius back-end is a MySQL database, the 'sql' statement in

authorize seems ok. And so do 'digest' in 'autheticate' section.

The question remains: Why are OpenSER complain on Radius response? Maybe

it's because of the sterman schema (?)....

Anyway, I try to test the server using the radtest tool. The output

seems good to me:

# radtest [EMAIL PROTECTED] 8201 127.0.0.1 12345 MyServerPassword
Sending Access-Request of id 255 to 127.0.0.1:1812
        User-Name = "[EMAIL PROTECTED]"
        User-Password = "8201"
        NAS-IP-Address = sip
        NAS-Port = 12345
rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=255,

length=35

        Reply-Message = "Authenticated"

So I discard FreeRadius config. Is this related on the value of “Reply-

Message”? I already read all Radius material that I found on OpenSER web-
page…

What am I doing wrong? What am I missing? As this same configs work with

SER 0.9.2, why did it not with OpenSER 1.0.x?

Edson.
