Re: [SR-Users] Kamailio 3.0.4 is crashed - sr-users

12 Sep 2011

      Hello,
try to keep the mailing list cc-ed -- others may be able to help you 
faster or this discussion will be helpful for different people.
The username_spec and password_spec were removed indeed, the first was 
useless since the username was taken from auth header and the second 
became parameter to pv_www_authenticate, see:
http://kamailio.org/docs/modules/3.1.x/modules/auth.html#pv_www_authenticate
You simply have to use something like:
if (!pv_www_authenticate("$td", "$var(password)", "0")) {
    www_challenge("$td", "0");
         exit;
}
Cheers,
Daniel

Hi Daniel,
Thanks Daniel for your answer.
It's very helpful for me :).
Actually i tried with using kamailio 3.1.4 (lastest kamailio) but i 
got the problem with auth module and parameter with auth module.
Because some parameters at auth module have changed.
http://kamailio.org/docs/modules/stable/modules/auth.html  [3.1.4]
But in 3.0.4 kamailio, i am using auth module with these parameter and 
it had error with new kamailio (3.1.4) . :(

Hello,

it seems like a buffer overflow happened previously, since the
crash is in malloc. Do you get any error messages is syslog? Can
you recompile with QM_DBG_MALLOC like explained in the next link
and try again watching the syslog messages?
http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory

On another hand, 3.0.4 is quite old, why are not using 3.1.4, it
is far more updated than 3.0 series -- we are just to release
first in 3.2 series. Upgrading from 3.0 to 3.1 is rather trivial.

Cheers,
Daniel
