Hello I have a ISPConfig 3 test server and a production ISPConfig 2 server. I'm creating master DNS zones on ISPconfig3, and creating slaves on ISPConfig2. Both servers use bind9 Zones are replicated OK, but I'm having a little problem with zone updates. When an A record is added, zonefile serial are increased, and slave server refresh its zonefile. But when an A record is deleted, record are deleted from zononefile, but zonefile serial are not changed, so slave server doesn't refresh Is this intented behaviour or is a bug?
which exact ispconfig version do you use? if i remember correctly, such a problem has been fixed in one of the last releases.
on my installation is the same problem. this is serious problem because my primary and secondary dns is slave to ispconfig ...
