Hi,

you cannot alter the content of the radius auth request only if you get into sources. Are you sure you need to do this? isn't it just a matter of configuration on your RADIUS server? what server are you using? and what is the logged error from server?

regards,
bogdan

OK. I have found the problem:

First I made some modifiacations:
in the radiusclient.conf
auth_order  radius
authserver  192.168.1.3:1812
acctserver  192.168.1.3:1813
dictionary /usr/local/etc/radiusclient-ng/dictionary (this files is the modified. dictionary.radius+dictionary = dictionary)

in the openser.cfg
if (!radius_www_authorize("")) {
    www_challenge("", "1");
    exit;
};
http://www.iptel.org/ser/doc/ser_radius/ser_radius.html --> good reference

But there is still the same problem. rc_auth fails. Because when I check radiusclient-ng.0.5.2 release notes, I see that "Change default bindaddr from localhost to *, this is better default choice; " When I replaced "bindaddr *" with "bindaddr localhost" then openser could send the radius authentication packet successfully.


But I have a new problem. I get access-reject from radius server. Because Radius server does not like the authentication packet parameters.

So I need to modify the outgoing packet params. Is it possible? And Can I also send additional "Vendor Specific Attribute" parameters?

I have also compiled "avp_radius" module and load it in openser.cfg. Nothing
changed.

As I see in the sterman.c source rc_auth fails:

/* Send request */
if ((i = rc_auth(rh, SIP_PORT, send, &received, msg)) == OK_RC) {
   DBG("DEBUG:auth_radius:radius_authorize_sterman: Success\n");
   rc_avpair_free(send);
   send = 0;

   generate_avps(received);

   rc_avpair_free(received);
   return 1;
} else {
   LOG(L_ERR,"ERROR:auth_radius:radius_authorize_sterman: "
   "rc_auth failed\n");
   goto err;
}

Any opinion?

Thanks in advance

Arda

Hi Arda,

you need to use auth_radius for this purpose. See:
   http://www.openser.org/docs/modules/1.1.x/auth_radius.html

Hi,
I have installed openser, mysql, radiusclient-ng-0.5.2 successfully on REL3.0. openser works well with mysql. I need to send a radius authentication packet to a radius server(according to RFC2865).
Packet contains base params:

User-name                    (attr.1)                    $Username

Password                      (attr.2)                    $Password

NAS-Identifier                (attr.4) (auto-generated)

NAS-Port                      (attr.5)                    $uref

State                            (attr.24)                  0

Client-Port-DNIS            (attr.30)                  NONE

Caller-Id                        (attr.31)                  $calling

I can not find a clear sample about radius. Which module is used for this purpose?
 Regards
 Arda
