[c-nsp] Changing SSH Port on IOS

[Charles Wyble]

Um..... why don't you setup some ACL to limit access? It's generally ill 
advised to run dameons with shell access directly connected to the 
internet. :)

I use OpenVPN for all my access, and only run SSH on the private 
interface. I realize this isn't always possible, but is a good solution.
