Some FTP server implementations implement the SFTP protocol; however, outside of dedicated file servers, SFTP protocol support is usually provided by an SSH server implementation, as it shares the default port of 22 with other SSH services. SFTP implementations may include an SSH protocol implementation to leverage integration of SSH connection ...
The IANA has assigned TCP port 22, UDP port 22 and SCTP port 22 for this protocol. [10] IANA had listed the standard TCP port 22 for SSH servers as one of the well-known ports as early as 2001. [11] SSH can also be run using SCTP rather than TCP as the connection oriented transport layer protocol. [12]

sftp is a command-line interface client program to transfer files using the SSH File Transfer Protocol (SFTP), which runs inside the encrypted Secure Shell connection. It provides an interactive interface similar to that of traditional command-line FTP clients. One common implementation of sftp is part of the OpenSSH project. [1]
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
One is that the FTP client and FTP server use the PASV command, which causes the data connection to be established from the FTP client to the server. [14] This is widely used by modern FTP clients. Another approach is for the NAT to alter the values of the PORT command, using an application-level gateway for this purpose.
