This works well, except when the SSH connection drops: PuTTY displays an error message, and I need to manually close the error and reconnect to the server. You can tunnel multiple ports if you like however, all require that the PuTTY secure shell connection stays active for data to pass over the tunnel to the remote server. Currently, I'm using PuTTY to open the two SSH tunnels: I log in to the server in PuTTY, leave it minimized, and never touch it. You should get the remote sign on screen of the system you are tunneling to. It will connect to the middle machine and prompt the terminal, you must leave this tab open. This will link your public machine with your destination computer via port 4040. Configure a new connection and use the parameters below:Ĭlick on Communications, and connect. Step 2: destination computer ssh -R 4040:localhost:22 middle-machine-usermiddle-machine-public-ip. After you are signed in, you must leave this window open to keep your tunnel active. Now you can launch your session and sign in to the secure shell. In the left pane, click on Session to bring up the following window. Select both Local ports accept connections from other hosts and Remote ports do the same.Ĭlick the Add button to place your tunnel configuration in the Forwarded ports window. localhost:23 will get you a Telnet connection. The Destination is the connection on your remote SSH machine. In the Port forwarding section, the Source Port is the source TCP/IP address you want assigned to your local host connection. Do not save this yet we have to configure the ports for tunneling.Ĭlick on the path to reach Tunnels ( Connection > SSH >Tunnels): It is available for Windows and for UNIX platforms. Now dont forget to create a mount folder ( any folder that the mount share will show up in). Now connect to your SSH Server (Computer A). Then click Add and make sure you SAVE the settings for that connection before you open that connection. Here are the steps to set it up: Setup putty to SSH from host A to host B. Make sure the Remote button and Auto button are selected. In this example, I will have a VNC Server running on host A that I want to get to with me using host C. Otherwise there will be two putty SSH connections, A to B, then C to B. Type the name you wish to use for the saved connection. PuTTY is a free, open-source implementation of several network protocols, including SSH. This way you can reverse tunnel directly from B to A. Open PuTTY.EXE, configure your host name, and select SSH for port. To configure a PuTTY session for tunneling Telnet traffic, do the following:
