How to set up a secure server

CompleteFTP supports secure FTP via the SFTP protocol (FTP over SSH), and the FTPS protocol (or FTP over SSL). CompleteFTP also supports SCP and HTTPS (but not in the Standard Edition).

FTPS

FTPS may be enabled by selecting the "FTPS enabled" setting (see the FTP/FTPS group of settings), and its use can be made mandatory (i.e. no 'plain' insecure connections) by unselecting the "FTP enabled" setting. In this case users can only use FTPS, and ordinary FTP connections will be rejected (i.e. initial connection to the server must be followed by the AUTH command).
By default, the FTPS and FTP port is port 21.

SFTP

SFTP may be enabled by selecting the "SFTP enabled" setting (see the SFTP/SCP group of settings). Similarly, SCP may be enabled by selecting the "SCP enabled" setting.
By default, the SFTP and SCP port is port 22.
SFTP, SCP and FTPS can be enabled simultaneously (and by default are).

HTTPS

HTTPS (which is HTTP secured over SSL/TLS) may be enabled by selecting the "HTTPS enabled" setting (see the HTTP/HTTPS group of settings).
