Use sshtunnel to connect to a LAN Machine

When you need a browser to open an intranet IP address, you can use putty to create a tunnel. As mentioned in my previous blog post;

You can also install the vnc viewer locally, log on to the login node, and use the browser of the login node to open the Intranet IP address;

Using ssh tunnel is the simplest method;

Example:

Node1 has a public ip address; node2 only has an intranet ip address; node1 and node2 communicate over the network;

We can only open the service of node1 in the browser; we can establish an ssh tunnel on node1 to obtain the service of node2 through the public ip address and port of node1 in the browser;

1. The intranet ip address of node2 is 10.0.0.189. We want to use the ip address of node1 to obtain the service with port 80 of node2;

Log on to node1 and run the following command. Enter the username and password as prompted to keep the current terminal window open:

# Ssh-L 80: 10.0.0.189: 80 10.0.0.189

2. Open node2_ip: 80/in the browser to see the service under port 80 of node1;
