Which of these protocols is used to run system commands on a device and is used for remote administration?

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?

The primary remote access protocols in use today are the Serial Line Internet Protocol (SLIP), Point-to-Point Protocol (PPP), Point-to-Point Protocol over Ethernet (PPPoE), Point-to-Point Tunneling Protocol (PPTP), Remote Access Services (RAS), and Remote Desktop Protocol (RDP).

What is the use of Telnet protocol?

Telnet is a network protocol used to virtually access a computer and to provide a two-way, collaborative and text-based communication channel between two machines. It follows a user command Transmission Control Protocol/Internet Protocol (TCP/IP) networking protocol for creating remote sessions.


SSH usually runs over TCP. That being said, RFC 4251 specifies that SSH transmission layer protocol “might also be used on top of any other reliable data stream”. SSH protocol’s default settings are to listen on TCP port 22 for connections. … Using TCP, SSH is able to accomplish port tunneling and forwarding.

What are access protocols?

Multiple access protocols are a set of protocols operating in the Medium Access Control sublayer (MAC sublayer) of the Open Systems Interconnection (OSI) model. These protocols allow a number of nodes or users to access a shared network channel.

Is telnet still used?

Telnet is rarely used to connect computers anymore because of its lack of security. However, it is still functional; there’s a Telnet client in Windows (10, 8, 7, and Vista), although you may have to enable Telnet first.

What is telnet in simple words?

Telnet is a common network protocol used on the Internet and also inside a LAN (local network). … Telnet is one of the simplest ways to exchange data between two computers. It allows two computers anywhere on a computer network, including the worldwide Internet, to exchange text and other data in real time.

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.


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.
