Remote desktop settings: Use putty for vnc + ssh tunneling

If you directly use vncviewer for access, there are two disadvantages:
1. Password transmission is in plain text and can be easily listened.
2. the firewall needs to open port 59xx, which is impossible in the normal unit.
Fortunately, we have ssh, a powerful tool, like X11 Forwarding. We can use the ssh tunnel to protect the communication process. The following is a brief introduction.
Assume that the vncserver runs on screen 1 of myserver (IP Address: 192.168.x.x), that is, It listens for 192.168.x.x: 5901, and the user name is foo.
Scenario 1: The vnc client is linux
This situation is very simple. ssh suites are installed by default in general linux releases.

1. log on to the server using ssh
Ssh-L 5901: localhost: 5901-l foo myserver
Or directly use an IP address.
Ssh-L 5901: localhost: 5901-l foo 192.168.x.x

2. Run vncviewer (or other similar tools) on another terminal on the local machine)
Vncviewer localhost: 1
Scenario 2: The vnc client is windows

1. Download an ssh client, personal recommendations putty, only one program, do not need to install, simple and functional. Download http://www.chiark.greenend.org.uk here /~ Sgtatham/putty/download.html
Download putty.exe and run it directly on the desktop.

2. Run putty, enter the IP address of the server, and enter a name. Here, myserver is used as the session name, and save it by pressing save (see figure 1 ).
3. Click tunnels on the left of the dialog box to select related settings, enter 5901 in source port, enter localhost: 5901 in Destination, and press Add (see figure 2 ).
4. Click session on the left side, return to session settings, and press save to save the settings. Click open to log on to the server.
5. if no vnc-viewer is run, download [url] http://www.realvnc.com/download.html#/url#, just use an exefile). Enter localhost: 1 on the Server. After the password is entered, a linux Desktop appears in windows, and it is very safe.
