Nmap Hackers: Nmap-2.00 doesn't recognize SSH?

[Vegard Svanberg <vegardsv () gravityzone com>]

Hello.

Why doesn't nmap-2.00 recognize SSH?  If I portscan mye computer here,
you'll get this report;

21      open        tcp        ftp
22      open        tcp        unknown
53      open        tcp        domain
80      open        tcp        http
110     open        tcp        pop-3
113     open        tcp        auth
119     open        tcp        nntp

As you can see, it recognizes all services except ssh (port 22).  I can't
quite see the reason for this?
