Hi Mark,
even if the same subscriber table is used, they will generate different
nonces. What you can do is to drop authentication on second proxy if the
source address is the first proxy.

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
<http://voipcall.com>", "subscriber")) {
www_challenge("voipcall.com
<http://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
<http://voipcall.com>", "subscriber")) {
www_challenge("voipcall.com
<http://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

Dec 4 23:26:01 /usr/sbin/openser[15365]: pre_auth(): Invalid nonce

Thanks,
Mark
