Hi, I am working on the following setup: Server 1 (Hostname=CSS1) Ubuntu 9.10 x64 with ISPConfig 3 Master: 192.168.1.201 ns1 (nameserver1) for myexample.com Server 2 (Hostname=CSS2) Ubuntu 9.10 x64 with ISPConfig 3 Slave: 192.168.1.202 ns2 (nameserver2) for myexample.com For the most part, everything is working very well. These screenshots (x3) show some tidying up I must do to get everything running smoothly. (They are from dnsqueries.com results for myexample.com). 1. How do I change the SOA REFRESH value? 2. How do I change the EXPIRE value? 3. Do I put another MX record in the ns1 zone or the myexample.com zone (sorry if this is a dumb question but I am struggling with the idea of DNS) The only zone I have on CSS2 (slave server) is ns2.myexample.com at the moment because I want to do zone transfers from the CSS1 (primary server) but don't know how to do this yet. I'm not sure which parts to fix first.
