Hi, I lastly installed two additional IPs to my server so I got 3 IPs at all. By doing this I mentioned problems while my slave dns was getting notified about new zone info from master because the masters ips were increased now to 3 IPs. In past (and now in present) the slave DNS expected to get zone update from IP1. But after having 3 IPs bind9 from master now selects IP2 to send notifies and so the slave always refused all updates. So I went through and found out how to force the master DNS to re-again using the (old) IP1 by putting: Code: listen-on {217.XXX.XXX.126; }; notify-source 217.XXX.XXX.126; in my named.conf.master template. that seems to be working at all I now get a "service warning" in ISPCONFIG that it is offline. I think this is because bind now listening on hard coded port instead of all localhost ports *. Here's whats netstat outputs for DNS: Code: tcp 0 0 saXXXXus.net:domain *:* LISTEN 11476/named saXXXXus.net is mit RDNS solver. what should I do? Hack the status-code for Bind? thx and greetings, melchior
