Select Add to add the settings, and then select Open to open an SSH connection. The port on the client that you wish to forward. Provide the following information on the Options controlling SSH port forwarding form: Property In the Category section to the left of the dialog, expand Connection, expand SSH, and then select Tunnels. The SSH address for the HDInsight cluster. If you don't already have a saved session, enter your connection information: Property If you've already saved a session, select the session name from the Saved Sessions list and select Load. Open PuTTY and ensure Session is selected on the left menu. Use the following steps to create an SSH tunnel using PuTTY: Create or load a session If you aren't familiar with PuTTY, see the PuTTY documentation. PuTTY is a graphical SSH client for Windows. Once the command finishes, traffic sent to port 9876 on the local computer is routed to the cluster head node. The -Nf will background the session and exit immediately back to your desktop, not establishing an actual shell session to server B. This will let you point your desktop browser at port 8443 and send it to port 443 (the HTTPS port) on your server A. Prevent reading of STDIN, since you're just forwarding a port.Äo not execute a remote command, since you're just forwarding a port.

Replace sshuser with an SSH user for your HDInsight cluster, and replace CLUSTERNAME with the name of your HDInsight cluster: ssh -C2qTnNf -D 9876 command creates a connection that routes traffic to local port 9876 to the cluster over SSH. This allows you to set up SOCKS compatible applications like your web browser to use the locally available proxy port. Use the following command to create an SSH tunnel using the ssh command. Using PuTTy as a SOCKS proxy, by contrast, is similar to SSH tunneling in how it works, but uses the SOCKS proxy protocol to forward various kinds of traffic instead of rigidly forwarding traffic from one source to one destination. An SSH tunnel is useful for port-forwarding, in the case of connecting securely to a remote database server. However, you can install extensions that support SOCKS5. Google Chrome also relies on the Windows proxy settings. The following browsers rely on Windows proxy settings, and do not currently work with the steps in this document: The SOCKS proxy support built into Windows Internet settings does not support SOCKS5, and does not work with the steps in this document.
