===rlogin===
{{See also|Telnet}}

{{code|rlogin}} enables a user to log in on another [[Server (computing)|server]] via [[computer network]], using [[Transmission Control Protocol|TCP]] [[network port]] 513.

{{code|rlogin}} is also the name of the [[application layer]] [[Communications protocol|protocol]] used by the software, part of the [[TCP/IP]] protocol suite. Authenticated users can act as if they were physically present at the computer. RFC 1282, in which it was defined, states: "The {{code|rlogin}} facility provides a remote-echoed, locally flow-controlled virtual terminal with proper flushing of output." {{code|rlogin}} communicates with a [[daemon (computer software)|daemon]], {{code|rlogind}}, on the remote host. {{code|rlogin}} is similar to the [[Telnet]] command, but is not as customizable and is able to connect only to Unix-like hosts.
