I just came from an ISPC 2 post where Till gave instructions on changing the master servers hostname but also stated its for 2 not 3. These were the instructions: as its a 2015 thread i don't want to dig it back up with an ISPC 3 question. To be fair my question or rather questions go beyond the scope a little as i'm actually midway through expanding from standalone to multiserver. So queston 1: How should i change the hostname on the master server, what files do i need to edit on the master and the slaves. Are they still the same files/locations or is there something else i will need to do. Now some info for the next question Not really sure I got the dns configured correctly on the master, I have primary zones but no secondary zones. So as you can guess this is my second question, is that configuration going to be okay like that or do i need the secondary set up.
