FTP service

The File Transfer Protocol specification was originally published in 1971, but we
currently use a specification from 1985 that everybody should really start moving
away from. FTP uses port 21.

A much newer specification known as Secure FTP (SFTP) supports the IPv6 and
Secure Socket Layer (SSL) encryption. Installing FTP will just be a waste of time
as SSH comes with built-in support and is enabled by default to use SFTP. SFTP
generally uses port 22, which is the same port as SSH.
