Hi,

this may be related to same issue reported at:
http://sip-router.org/tracker/index.php?do=details&task_id=114

Therefore it can be just some log message printed erroneously. Can you dump the htable content (or print it with xlog) to see if the assignment is actually done or not?

Dumping the htable content:

kamctl fifo sht_dump a

Another possible issue I spot with your config is that you don't check for the existence of Authorization header. Since I am not using auth_radius, I am not sure radius_www_authorize() return -1 only when the password mismatches. Might be also when there is no header carrying the credentials. If no Authorization header is present, the $au is null -- in this case you just have to do www_challenge() and exit, since counting failed authentications for "<null>" user might bring you unexpected behaviour.

Regards,
Ramona

Hello

I’m trying to use “htable” module with the example to block a user with three time s failed password.

When a REGISTER arrives I’m getting this error :

Feb 18 17:26:34 /usr/local/sbin/kamailio[5840]: ERROR: <core> [lvalue.c:358]: setting pvar failed

Feb 18 17:26:34 /usr/local/sbin/kamailio[5840]: ERROR: <core> [lvalue.c:411]: assignment failed at pos: (322,54-322,81)

Feb 18 17:26:34 /usr/local/sbin/kamailio[5840]: ERROR: <core> [lvalue.c:411]: assignment failed at pos: (328,47-328,49)

 

The lines pointing the error are these :

 

312    if ( !radius_www_authorize("10.0.0.208") )

313    {

314            switch ($retcode)  {

315                    case -1:

316                            xlog("L_INFO","authentication failed from radius\n");

317                            if($sht(a=>$au::auth_count) == "null")

318                            {

319                                    $sht(a=>$au::auth_count) = 0;

320                            }

321                            $sht(a=>$au::auth_count) = $sht(a=>$au::auth_count) + 1;

322                            if($sht(a=>$au::auth_count) == 3)

323                            {

324                                    xlog("L_INFO","auth failed 3rd time - src ip: $si\n");

325                            }

326                            $sht(a=>$au::last_auth) = $Ts;

327                    break;

328                    case -5:

329                            sl_send_reply("403", "Forbidden");

330                    exit;

331            }

332            www_challenge("10.0.0.208", "1");

333            exit;

334    }

 

What could be the problem?

 

Thanks in advance.

Regards,

Ricardo.-
