nmap: state closed on SSH port. What does that mean?
Hello
I had trouble getting into my server with SSH. I did nmap on it and go the below: iskmb@iskmweboffice:~$ nmap -P0 a.b.c.d Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2007-04-26 08:15 BST Interesting ports on . (a.b.c.d): (The 1660 ports scanned but not shown below are in state: filtered) PORT STATE SERVICE 22/tcp closed ssh 8080/tcp open http-proxy 8443/tcp open https-alt What does state "closed" mean? Any why would it happen? Thanks Hamish |
I will copy literally from the Nmap reference Guide:

Your ssh is probably not running. Check with: ps aux | grep ssh Are you doing this from the localhost? First try on the host where ssh is running on: ssh username@localhost If this works, your firewall probably blocks it. |
