Telnet is a program that allows a computer user at one site to work on a computer at another site. It is the Internet standard protocol for remote terminal connection service.

Telnet requires Internet access, that is, you must be on a TCP/IP network that gateways to the Internet. Unlike FTP and electronic mail, Telnet actually exposes you to the commands and programs of the remote host.

In most cases, a user must make arrangements beforehand to use telnet on a remote host. Some interactive programs allow any network traveller to log in with no password or a password that is advertised. Sometimes the password is "anonymous" and the password can be "guest." The type of activity allowed with anonymous telnet is restricted.

rlogin (remote login)

A program and protocol provided in Berkeley UNIX (see BSD) that permits a user on one computer to log in to another computer. This protocol is largely implemented among UNIX machines, but the protocol is general enough that non-UNIX machines may use it. For example, Excelan ANNEX terminal concentrators permit users on dumb terminals to use the rlogin protocol to communicate with Internet computers.
