#SSH TUNNEL WINDOWS VISTA INSTALL#

You can check that it's listening on the correct port with this: local:~# netstat -tulpn | grep LISTEN | grep appname The tunnel is working! But what if you have an application, called appname, which is supposed to be listening on port 456 on the local machine? Terminate nc on both sides then run your application. You should see this being mirrored on the local terminal: local:~# nc -l 127.0.0.1:456 Tcp 0 0 localhost.localdo:33826 localhost.localdom:456 ESTABLISHEDīetter still, go ahead and type something on the remote: remote:~# nc 127.0.0.1 8888 Tcp 0 0 localhost.localdom:456 localhost.localdo:33826 ESTABLISHED Something like this: local:~# netstat | grep 456 When the remote server can connect to the developer machine directly (for example, with a Vagrant machine), an SSH tunnel may not be needed. If you open a second terminal to the local machine, you can see the connection. The SSH tunnel is used for connecting through a firewall and establishing a secure connection between the remote server and the developer machine. Then make a connection on the remote: remote:~# nc 127.0.0.1 123

On CentOS it can be installed with yum install nc.įirst, open a listening port on the local machine: local:~# nc -l 127.0.0.1:456 Would be nice to actually see some data going through from the remote to the host.

Start a http server on port 8080 devtunnel echo http -p 8080 Tunnel port 8080. Host a tunnel for the local port 8080 that is accessible to the internet. Run a local server on port 8080 that echoes requests sent to it. Ssh Tunnel Easy is an innovative ssh tunneling software, it can make an encrypted ssh tunnel Between your machine and ssh server host, then tunnel your. We should get an output similar to this: tcp 0 0 10.0.3.12:ssh 10.0.0.1:45988 ESTABLISHED Once logged in you can start hosting a tunnel using the host command. Next, we want to check that the tunnel is open on the remote: remote:~# netstat | grep 10.0.0.1 Note that excluding the username before the remote IP, makes ssh use the current username. Otherwise, check that the SSH key is installed in the remote. If you see the command in the output, we can proceed. To check that the process is running, we can do: local:~# ps aux | grep ssh This can be done with the following command, on the local machine: local:~# ssh -N -R 123:127.0.0.1:456 10.0.3.12 The goal is to create a tunnel that will forward TCP traffic from the loopback address on the remote machine on port 123 to the local machine on port 456. I will prepend these hostnames, to the commands below, so it's obvious where they're being executed. Assume there is a machine, which will be called local with IP address 10.0.0.1 and another, called remote, at 10.0.3.12. And I couldn't use nc -z because that option wasn't available on my incantation of netcat. Just grepping for the ssh process wasn't enough, as it was still there. I'm adding this answer because I had to troubleshoot the link between two applications after they stopped working. These are more detailed steps to test or troubleshoot an SSH tunnel.
