If that means 100% secure, then you have a problem. Defining how difficult it is to break SSH also depends largly on you knowledge of computer networking, especially cryptography and how SSH is implemented in FreeBSD. I guess you should do a google search for all of this(Bruce Schneier has a relatively good book on Cryptography and Hill on Coding Theory) but for remote control of your computer I would prefer keeping port 22 and SSH because it is relatively secure in the end. /sondre
