Running a local SSH tunnel

- [Scott Simpson] Local port forwarding allow us to assign a…local port, and have that tunneled to a remote service.…This can be useful when you want to retain…a common connection, but have the ability…to change where it connects to.…Let's see how we do this.…I'll use SSH to create a local connection…to tunnel into our metasploitable server.…I'll set up local port 8080 to do this.…

If I look up port 8080 on Kali…I can see there's no service running.…I'll now use SSH to connect to my…metasploitable server on port 80.…But I'll access it by using ports 8080…on my local Kali host.…I'll use the -NNT switch to tell SSH not to set up…a terminal, and -F to background the SSH process.…

- L indicates that this is a local port forwarding request.…SSH has created the tunnel, and we've now got a local access…connection from Kali to the metasploitable web server.…Let's try it out.…And I can see the metasploitable webpage.…

Let's now use LSOF to get the background process ID…and kill it.…We can see SSH is running on herd 2324.…
