I won’t go into too much detail in this post, as there are multiple guides
that go above and beyond in explaining the behind-the-scenes of tunnelling
VNC connections through SSH. Note that this solution uses TigerVNC’s
to control the remote X server. Simply use
vncserver if you want to control
a different X server.
The setup is quite simple, but requires two terminal windows. In the first terminal, SSH into your remote machine with
[email protected] $ ssh -Y <remote.machine.com> -L 5900:localhost:5900
[email protected] $ x0vncserver -display :0 -passwordfile ~/.vnc/passwdfile
Now, in the second terminal on your local machine, you can simply type
[email protected] $ vncviewer localhost:5900
-L flag in the SSH connection sets up port forwarding from the local machine
to the remote machine. In short, all unbound traffic that goes through the specified
port on the local machine is forward to the other port on the remote machine. Here we
choose port 5900 on both machines as it is the default port for
but both can be changed freely.
Make sure to generate a password file for VNC by using
vncpasswd and pass
x0vncserver on the
passwordfile flag. Here we choose the default.
The same method with generic ports would read
[email protected] $ ssh -Y <remote.machine.com> -L <xxxx>:localhost:<yyyy> [email protected] $ x0vncserver -rfbport <yyyy> -display :0 -passwordfile ~/.vnc/passwdfile
[email protected] $ vncviewer localhost:<xxxx>
Until next time, cheers!comments powered by Disqus
