Telnet could of course attempt to connect. And nmap could tell you every port open on the other system (at least to packets coming from your system, if some filtering is in use), although some might regard an nmap scan as a preliminary to hostilities.<div class=""><br class=""></div><div class="">Telnet is in the inetutils port, as gtelnet.</div><div class=""><br class=""></div><div class="">nc can attempt to connect to either TCP or UDP ports, and is included with macOS.
