Hi Largo,

for questions related to OpenSER, the right mailing list is users@openser.org . I will redirect your email there.

Hi Bogdan,

I got a problem regarding the t_replicate function. I got an openser server working as a loadbalancer with (DISPATCHER); let´s call it OPENSER-0. He is dispatching to 2 openser servers ; let s call them OPENSER-1 and OPENSER-2.

Everything works fine, but if one analyses the packets and the error logs closely, we observed the following:

• Every day there is only one of the servers who is correctly woking ,

the second one sends always a "404 Not Found".

• There are problems by replicating: OPENSER-1 as example, receives a

"401 Unauthorized" back from the OPENSER-2

• And in the syslog files , I see this:

/Jul 14 13:58:56 OPENSER-2 /usr/local/sbin/openser[30005]: PG[224] str2valp got string f3415bc4b2e66989142d134d0d33be91 Jul 14 13:58:56 OPENSER-2 /usr/local/sbin/openser[30005]: PG[224] str2valp got string Jul 14 13:58:56 OPENSER-2 /usr/local/sbin/openser[30005]: SRC not 23: Replicating... /

• Here are scarps from the openser.cfg Files of the 3 servers (only

important configs)
