In this scenario both the Hub server is running on Linux and LHigh Volume Agent is running on Windows 2016 Server. Now test connect from Local Data Processing location That connection request will be forwarded to the remote computer.
So-somewhat counter-intuitively-to make a connection to the remote computer, we ask Local Data Processing to make a connection to the local computer, on port 4344. The remote computer is listening on port 4344 on the local computer.

You can set up ssh keys instead of a password for authentication.īecause the connection from the remote computer is successful, and it is listening for connections, we can try to connect to the remote computer from the local one. You will be prompted for the password of the account you are using to connect to the local computer. What you see-if anything-depends on whether connections have ever been made from the remote computer to the local computer. Or you may see a warning as the connection details are added to the list of recognized SSH hosts. You may get a warning about having never connected to the local computer before. 4344:localhost:4344 tells ssh that connection requests to port 4344 on the local computer should be forwarded to port 4344 on the remote computer. On Server A use -R (reverse) option to tell ssh that a new SSH session must be created on this server. Start remote listener for Agent on port 4344 If SSH daemon is not started, start it using Inbound rules are allowed on ports 22, 4344, and 4345 On Server B, Local Processing Hub remote listener is listening on port 4345. On Server A, the High Volume Agent is listening on port 4344. I have server A which is designated to be High Volume Agent and server B which is designated to be Local Processing Hub.
In this scenario, both the Hub and High Volume Agent are running on Linux. This provides a new connection from the local computer to the remote computer. If it detects an SSH request to that port, it relays that connection request back to itself, down the established connection. The remote computer listens on a network port on the local computer. Reverse SSH tunneling relies on the remote computer using the established connection to listen for new connection requests from the local computer. This means your connection to the remote computer acts as a private tunnel inside the original connection.Īnd so we arrive at the name “reverse SSH tunneling.” How Does It Work? Reverse SSH tunneling allows you to use that established connection to set up a new connection from your local computer back to the remote computer.īecause the original connection came from the remote computer to you, using it to go in the other direction is using it “in reverse.” And because SSH is secure, you’re putting a secure connection inside an existing secure connection.

This document describes how to set up SSH tunneling for connecting Agent to Local Processing Hub when Agent is hard to reach from Hub or if there are no routes open from Hub to Agent.
