Telnet, developed in 1969, is a protocol that provides a command line interface for communication with a remote device or server, sometimes employed for remote management but also for initial device setup like network hardware.
Which protocols is used for remote administration?

Is port 22 UDP or TCP?
Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 22, UDP Port 22 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 22 to process any errors and verify correct delivery.
Is FTP UDP or TCP?
FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a ‘data’ port and a ‘command’ port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port.
