The ONLY difference between my actual work and these instructions is of course my user name. Why is this not working? There are multiple sites with instructions, but they all lead me to the same place. # Clean any existing files in /tmp/.X11-unix environmentĮxecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'ĮxecStart=/sbin/runuser -l matt -c '/usr/bin/vncserver %i -geometry 1280x1024'ĮxecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' # Use '-localhost' to prevent remote VNC clients connecting except when # Use '-nolisten tcp' to prevent X connections to your VNC server via TCP. # the help of ssh, you end up seeing what hostB makes available on port 590M # You can then point a VNC client on hostA at vncdisplay N of localhost and with # See the ssh man page for details on port forwarding) # (in fact, it ssh-connects to hostB and then connects to localhost (on hostB). # this will open a connection on port 590N of your hostA to hostB's port 590M # whose VNC output you want to view (host B) # the machine you want to view VNC on (host A) to the machine # limit connections to the local host and then tunnel from # untrusted!
