Port property specifies what local port is used for
accepting new connections. Its default value 22 is well
known and 'registered' for usage of SSH protocol
applications, but in specific cases you might want to
change it to something else. If you do so, please notify
users that will use your server for new port number.
When you choose this value, please be sure that selected
port is 'not taken' by some other application. If
you're not sure if it's available or not, easiest
way to find out is to execute 'netstat
-a' from command prompt and check if there's
'22' value listed in 'Local Address'
column. In default installations of all Windows operating
systems, no SSH server will be installed so you don't
have to worry about this.
You cannot change value of this property when your
server is running. If you want to change it, first Stop the server, change
the port, and then Start it again. If
there are any users connected at that time, they will be
disconnected.
