Some protocols designed to transmit data over UDP also use a TCP port for oversight. The " Server port " column indicates the port from which the server transmits data. In the case of FTP , this port differs from the listening port.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
The standardization of TCP and UDP reduced the need for the use of two simplex ports for each application down to one duplex port, [13]: 15 but the FTP protocol was never altered to only use one port, and continued using two for backwards compatibility.
It is possible, however, to run it over SSH-1 (and some implementations support this) or other data streams. Running an SFTP server over SSH-1 is not platform-independent as SSH-1 does not support the concept of subsystems. An SFTP client willing to connect to an SSH-1 server needs to know the path to the SFTP server binary on the server side.

It also supports mechanisms for tunneling, forwarding of TCP ports and X11 connections and it can be used to transfer files using the associated SSH File Transfer Protocol (SFTP) or Secure Copy Protocol (SCP).

The SCP is a network protocol, based on the BSD RCP protocol, [5] which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and uses the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit.
