@unborn: ProFTP also supports FTP over ssh via the mod_sftp plugin, and we enable that feature on port 2222. This allows for people who don’t want to offer full ssh access to their users via ssh, but do want to offer FTP over SSH. It’s not dangerous, ProFTPd is well-maintained software with a pretty good security record. FTP without encryption is dangerous, but there are multiple ways to connect to FTP with encryption and we support two of them (FTP with SSL/TLS and FTP over ssh, via both openssh and proftpd). @Nico94 is right, you’re wrong (and unnecessarily grouchy about it). 
I guess I need to update Virtualmin-Config to handle this better.
