    I just installed ISP Config on Debian 7 and when i go to server config page i get ERROR Invalid Hostname.

    What is causing this and how can i fix it?
    Did i do something wrong in the installation process?

    I changed the hostname in the VPS control panel to the domain name, reinstalled ISPConfig and now it is working.

    The hostname is a fqdn like server1.example.com. So the text string that you entered (or that was set by your virtual server controlpanel for the vm) is a wrong hostname and therefor ispconfig rejected it.

    then it means that ispconfig 3 requires dns server to function ?? Because if it need a FQDN ??

    No. It just means that you have to enter an FQDN and not just the local part as some software like amavis will not start without it.

    I ran into the same problem today. I was testing the new ISPConfig when I encountered this error.
    Is there a way to change the hostname on my system without loosing my data/ISPConfig installation?
    Already tried changing /etc/hosts, /etc/hostname and rebooted but nothing changed.

    Step by step guide would be highly appreciated. Server is running on Debian 8.5 Jessie with Apache2, BIND, Dovecot & ISPconfig 3.1b2. :)

    You have to set the new hostname in the hostname field of the server config in ispconfig as well. Beside that, the wrong hostname can also be in the files /etc/mailname and /etc/postfix/main.cf.

    Problem is, that I can't change the hostname in ISPConfig, since it also results in the error message 'Invalid Hostname'.

    The message occurs when the hostname that you entered contains an invalid char. A valid hostname is e.g. server1.example.com

    Why is it impossible to let the hostname be and go to different tab (e.g. Cron) in this settings? It still won't let me even when I didn't change it and use just what was preconfigured.

    To be honest I don't know what will change to that hostname do, because I have preconfigured server from my VPS provider. I don't want to create some mess when I don't know what this settings affect...
