Using VNC through SSH (vnc over SSH)

In addition to the Ssh,linux platform, you can access remote machines in a graphical way, the most popular of which is VNC

VNC connections, however, are not secure and are easily intercepted and monitored, so a safer way to use vnc,ssh security through an SSH tunnel is guaranteed.

Very simple, use SSH to do port forwarding

Terminal mode

$ ssh-l 5900:localhost:5900-n-F Sshserver_ip_or_name

Parameters

-L [Bind_address:]port:host:hostport forwards the specified port of the local host (SSH client) to the specified port on the remote host,-L 5900:localhost : 5900 Specifies that 5900 ports of any local interface are forwarded to the 5900 port of the remote localhost interface. VNC server's default starting port is 5900, then add the display number, if the VNC server on the No. 0 display monitor, its listening port for 5900+0 is 5900, if the monitor on the 1th display, its listening port is 5900 + 1 is 5901, and so on.

-N does not perform remote commands. This SSH connection is for port forwarding only.

-F to place ssh in background execution

Then use the VNC Viewer to connect to the local 5900 port

$vncviewer 127.0.0.1[:5900]
