VNC
Setup
Follow instructions at Fedora documentation.
Password length on server should be maximum 8 characters. Further characters are ignored.
Use display numbers starting from 1 without skipping (1, 2, 3, …).
$ sudo systemctl start vncserver-<userA>@:1.service
$ # sudo systemctl start vncserver-<userA>@:3.service <--- This would fail
$ sudo systemctl start vncserver-<userB>@:2.service
$ sudo systemctl start vncserver-<userC>@:3.service
...
To prevent unencrypted connections, add the arguments -localhost
and
-nolisten tcp
to the ExecStart line in systemd
unit
ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver -localhost -nolisten tcp %i"
Connection
Create encrypted connection to server
$ ssh -L <localport>:localhost:<remoteport> -N -f -l <loginname> <hostname>
Open VNC client
$ vncviewer &
And enter localhost:<localport>
and password.
