telnet
A client program for the telnet remote login protocol
Telnet is an old protocol for logging into remote systems. It is rarely used, since the transfer is not encrypted (ssh is mostly used these days). The telnet client is often used for debugging other network services. The command telnet localhost 25 connects to the local smtp server, for example.
