Telnet is a popular protocol for logging into remote systems over the Internet. The telnet package provides a command line telnet client as well as a telnet daemon, which will support remote logins into the host machine. The telnet daemon is enabled by default. You may disable the telnet daemon by editing /etc/inetd.conf. Install the telnet package if you want to telnet to remote machines and/or support remote logins to your own machine.
