I have 3 servers, a master and 2 slaves. The 2 slaves will only be for the primary and secondary DNS. I accidentally installed the master with all the options, as if it were going to manage everything. But in the DNS options it keeps appearing, which I don't want. To solve this, the correct option would be for me to go to System > select the master, and deactivate the DNS-Server option. And later I can use the following commands?: Code: apt purge bind9 dnsutils apt autoremove apt autoclean apt clean Or is there a more correct way to do this? PS I'm going to transfer some sites from another system, I'm going to start using ISPConfig to manage everything, so I want the servers to be as clean as possible for production.
