I have a question regarding binary replication, I was using OpenSIPS 1.7 until now, my backup was passive, because when they were all up at the same time, the usrloc timer from the backup kept on removing users from the database, even though I'm using mode 2, I still rely on the DB for some actions, I recently watched Vlad Paiu video presentation on Binary Interface replication and he says that he advises to leave the backup open too, so I built 2 test servers with OpenSIPS 1.11 and I have a few questions.
1) will this solve the issue of the usrloc timer deleting records? 2) will it also update the backups database if I use mode 2? this way I dont need to replicate the db's, i will have 2 separate db's and have each server update its own db, if it does this will also solve problem 1. 3) I tested the bin replication, when doing a ngrep I see the packet coming in on the backup when a new user registers, but when doing a "opensipsctl ul show" it only shows the contact line and nothing else and it disappears completely after a few moments and it does not update the db. 4) Does it have a built in security mechanism besides manually doing it with iptables? 5) It seems like this is mainly used with a floating ip, I have servers on the same network using floating ip, I also have servers on different networks using failover dns, how will it affect my redundancy, I assume the backup server wont be able to reach the client before the client does a new DNS lookup and re registers, because the clients NAT wont allow it through, is that correct? and is there a solution for that? thanks in advance S.
