If any of you guys use putty for SSH, to connect to a remote SSH server and you find a firewall is blocking port 22 // change the SSH listening port to 443 (https) port. Most firewalls allow access to this port. When working in the NHS I regularly used to connect to my SSH server and came across this same issue. Changing the listening port can be quite a pain depending what the SSH service is running on.
For the server I run // It runs on Windows XP and is called Cygwin the installation instructions can also be found on the site, which tells you details on how to change the listening port and extra packages you need to install when Cygwin is installed.
I find this piece of software is better to use if you don’t want multiple PC’s running at home. I do find the connection drops out quite abit, where as when I had my Linux machine running with the SSH service I never came across this issue. Not sure if it is a setting that I have missed or a glitch within the app.
