I'm done - I don't get ProFTPd to start... I tried everything. If I start proftpd with

> 
> /etc/init.d/proftpd start
> 
> 
> 

I get the following:

> 
> [....] Starting proftpd (via systemctl): proftpd.serviceJob for
>  proftpd.service failed. See 'systemctl status proftpd.service' and
>  'journalctl -xn' for details. failed!

Output of "systemctl status proftpd.service":

Two thing I don't understand:

1. "unable to determine IP address of 'root.MYDMOMAIN.de'" what does this mean? Have I to set a subdomain with "root"?
2. "error processing configuration file '/etc/proftpd/proftpd.conf'" config broken? I checked my config with another config from another server - it's the same...

If you need the proftpd.conf tell me - post would be to long for that.

Pls help me :( thanks.
