# The vncserver service unit file # # Quick HowTo: # 1. Add a user mapping to @CMAKE_INSTALL_FULL_SYSCONFDIR@/tigervnc/vncserver.users. # 2. Adjust the global or user configuration. See the # vncsession(8) manpage for details. (OPTIONAL) # 3. Run `systemctl enable vncserver@:.service` # 4. Run `systemctl start vncserver@:.service` # # DO NOT RUN THIS SERVICE if your local area network is # untrusted! For a secure way of using VNC, you should # limit connections to the local host and then tunnel from # the machine you want to view VNC on (host A) to the machine # whose VNC output you want to view (host B) # # [user@hostA ~]$ ssh -v -C -L 590N:localhost:590M hostB # # this will open a connection on port 590N of your hostA to hostB's port 590M # (in fact, it ssh-connects to hostB and then connects to localhost (on hostB). # See the ssh man page for details on port forwarding) # # You can then point a VNC client on hostA at vncdisplay N of localhost and with # the help of ssh, you end up seeing what hostB makes available on port 590M # # Use "nolisten=tcp" to prevent X connections to your VNC server via TCP. # # Use "localhost" to prevent remote VNC clients connecting except when # doing so through a secure tunnel. See the "-via" option in the # `man vncviewer' manual page.
