VNC Connect from Mac OSX El Capitan to Ubuntu Linux

Edit 2016-11-05

This is actually trivial; here are the steps:

1. On the remote Ubuntu “workstation”, run:

$ vncserver

1. On the home Mac machine, run your favorite SSH tunnel:

$ ssh -t -L 5901:localhost:5901 workstation

1. Open up the VNC screen in a Mac window:

$ open vnc://localhost:5901
