#Putty create ssh tunnel windows

Once you have your private RSA key as a ppk file, you can move on to the next step. From this session connect to your default. If you do not yet have an RSA key pair (public and private), the above linked PuTTYgen tool can generate one for you. Create your own Virtual Private Network for SSH with Putty Open a putty session and configure it to act as a tunnel. The program is simple enough to use, I don't think you'll have any problems with it. To convert your RSA private key to this format you can use PuTTYgen (can be found here search for 'puttygen.exe' in that page). If you already have a private RSA key, you will need to convert it to ppk format so that PuTTY can use it. If you're using Linux or Mac, it's probably easier to simply use the terminal (or Secure Shell program) that is already installed on your system. An SSH tunnel is useful for port-forwarding, in the case of connecting securely to a remote database server.

#Putty create ssh tunnel windows

Thus it can replace the need for a VPN in a way.This guide will walk you through the steps needed to setup an SSH tunnel from a Windows machine using PuTTY. Using tunneling is good for security because the connection is encrypted and you don’t have to expose services to the outside. This will have the same effect as in the Putty. In the ssh console command simply specify ssh -L 8080:localhost:8080 when connecting to the remote host. There are a few configurations that you must set precisely to get the SSH tunneling working with your RSA key. With a Linux local box you can use simimlarly tunneling. Just open in your local browser and you will be connected to the remote server on TCP port 8080 via the SSH tunnel. Now you are ready to test your connection. If you need to connect to a different server through the remote host, you can specify it in place of localhost.ĭon’t forget to click on the Add button before establishing the connection.

In the above example, the tunnel will be from the local TCP port 8080 to the remote TCP 8080 on localhost.

Once you make sure tunneling is not forbidden, you can configure Putty by going to Tunnels tab in Putty’s configuration as seen below. The setting is called PermitTunnel and by default, in most configurations such as in CentOS, tunneling is allowed. You should know that SSH tunneling does not depend on the local OS and in this example I’ll use it with Windows and Putty.įirst, make sure tunneling is allowed on the remote server in the SSH daemon configuration. This can be easily done with SSH tunneling. At the same time you wish to test the Tomcat and you need to connect to TCP 8080. Select the Dynamic radio button under Destination. In Source Port enter 8080 (this can be configured to be whatever you want, just remember it). On the left side, go to Connection->SSH->Tunnels. Save this session by entering a title under Saved Sessions and press Save. The only connectivity you have to this remote host is SSH, i.e. Run the client and enter the hostname and port. Imagine, there’s a remote host which runs a Tomcat app servlet on TCP port 8080.

The second SSH session (via command line) Once you are connected to jumphost server, you can now create the second SSH session to connect to the appserver and create a tunnel from the jumphost's local port 1521 to the port 1521 of the dbserver machine. Thus, to gain remote network access you can use a tunnel to a remote host which would act as an intermediary. Use this Putty session to log in to the jumphost server with user myusr. SSH tunneling is very useful when the network access to a remote network is restricted.
