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:

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

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

http://openser.org/cgi-bin/mailman/listinfo/users 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
