I have the following set-up.
Home pc ---reverse ssh tunnel---> to linux server
The reverse ssh tunnel is set-up so that on my home pc, port 22 is open, but I have nothing currently listening on that port.
My intent was to leave a VNC server running on that port (on my home pc), and have my linux server act as a middle man, so I can VNC into my home pc when I travel. However, I have forgot to start the vnc server.
So I have two questions
1- Is there anything I can do from my end remotely, knowing that port 22 is open on my home pc through the SSH tunnel.
2- Let's assume for a second that port 22 was open to the whole world not just through the SSH tunnel, does this create any vulnerability, knowing that there are no services listening to port 22 on my home pc.
