[Users] t_replicate: Invalid nonce balue received - sr-users

5 Dec 2006

Hi,
I'm attempting to use t_replicate in order to load balance the registration
proxy.  However,
when the REGISTER packet goes to proxy2, it says "401 Unauthorized".

Both openser installations are working off of the same mysql database.
The first proxy has a srv record for the domain being served, the second
does not.

The first openser.cfg looks like this:

        if (uri==myself) {
                if (method=="REGISTER") {
                        # Uncomment this if you want to use digest
authentication
                        if (!www_authorize("voipcall.com",
"subscriber")) {
                                www_challenge("voipcall.com", "0");
                                exit;
                        };
                        save("location");
                        t_replicate('proxy2');
                        exit;
                };

the second looks like this:
        if (uri==myself) {
                if (method=="REGISTER") {
                        # Uncomment this if you want to use digest
authentication
                        if (!www_authorize("voipcall.com",
"subscriber")) {
                                www_challenge("voipcall.com", "0");
                                exit;
                        };
                        save("location");
                        exit;
                };

Both openser instances have aliases for the domain, and as I said before,
are operating off of the same database backend.
Furthermore, if I set the sip client's sip domain so that it will register
directly with proxy2, the phone registers with now problem.

However, when the t_replicate executes,
syslog says this:
Dec  4 23:26:01 /usr/sbin/openser[15365]: check_nonce(): comparing
[4574af56734dbd1d5c2c81242a74ba5cb5703c79] and

Thanks,
Mark
