Telnet is a type of client-server protocol that can be used to open a command line on a remote computer, typically a server. Telnet is most likely to be used by program developers and anyone who has a need to use specific applications or data located at a remote machine. If accepted, the user is granted access to the remote host. The result of this request would be an invitation to log on with a user ID, and then the program would prompt the user for a password. On the web, Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP) simply enable users to request specific files from remote computers, while, through Telnet, users can log on as a regular user with the privileges they are granted to the specific applications and data on that computer.Īn abstract example of the syntax for a Telnet command request is as follows: It follows a user command Transmission Control Protocol/Internet Protocol (TCP/IP) networking protocol for creating remote sessions. 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.
