# The vncserver service unit file

#

# Quick HowTo:

# 1. Copy this file to /etc/systemd/system/vncserver@.service

# 2. Edit <USER> and vncserver parameters appropriately

#   ("runuser -l <USER> -c /usr/bin/vncserver %i -arg1 -arg2")

# 3. Run `systemctl daemon-reload`

# 4. Run `systemctl enable vncserver@:<display>.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.
