All machines in the labs, classroom and faculty offices should already have an ssh client installed on them and those machines which allow remote access are running an ssh daemon to accept incoming connections.```````````````````` text/html 2012-12-01T17:30:48+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.cs.vassar.edu/old_pages/status/2012_workstations?rev=1354383048&do=diff 2012 Workstation Upgrades [LightDM screenshot ]Welcome back.

The big advantage over AIM is that XMPP is decentralized. Your messages only go as far as the servers involved, so it saves electricity and network traffic.

You will, however, need to download two programs: a SSH client and a VNC client. The SSH client will make a secure connection between your computer and the VNC server and the VNC client will use this connection to draw a display on your screen.
