Tcp 0 0 127.0.0.1:456 0.0.0.0:* LISTEN 2964/appnameīy the way, running the same command on the remote should show sshd listening on port 127.0.0.1:123.Got a list of proxies you want to check? Want to build up your own proxy list? Want to check proxies easily, quickly, and without installing any software? You’re in the right place. 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 ![]() If you open a second terminal to the local machine, you can see the connection. Then make a connection on the remote: remote:~# nc 127.0.0.1 123 #Ssh proxy checker install#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. We should get an output similar to this: tcp 0 0 10.0.3.12:ssh 10.0.0.1:45988 ESTABLISHED 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. ![]()
