Hello, I would like to change the server name (e.g. server1.mydomain.com) that I set during installation. I tried to change it from System > Server Services > "Servername" field, and also from System > Server config > "Hostname" field, and actually it has successfully changed on ISPconfig panel, but if I access the server via SSH and run "hostname" and "hostname -f" commands the server name is not changed. How can I change the server name at system level? Thank you
