  "whatItIs": "Deskflow, and the Synergy, Barrier and Input Leap family it descends from, lets one keyboard and mouse control several computers by moving the pointer off the edge of a screen. The server listens on TCP 24800 and clients connect to it; the protocol carries mouse motion, key events and clipboard contents, and version 1.4 and later can wrap the connection in TLS. The default is hard-coded across the codebase and documentation, so an open 24800 on a desktop is almost always this. It is a workstation port, not a server one.",
