Does second nameserver also need ISPConfig. (solved) Hello, Momentary I have got got one computer running on Centos 5.5 with ISPConfig 3. I am trying to build a second nameserver on an old computer. This one only functions under Centos 4.8. Do I need to install ISPConfig on this one to? I found only a howto with ISPConfig 2, is this a problem? Does ISPConfig 3 not function with Centos 4.8? Can I try to use a Centos 5.X to install ISPConfig 3? Can I copy named.conf to the second computer and putting slave instead of master in the zones? With kind regards, Ad.
