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?


Er ... does you /etc/services include a line like

ssh             22/tcp                          # Secure shell

When you use functions like getservby[name|port] they will scan *your*
/etc/services file and look for the corrispondent name/port.

[man getservbyname e.g]

DESCRIPTION
     The getservent(), getservbyname(), and getservbyport() functions each re-
     turn a pointer to an object with the following structure containing the
     broken-out fields of a line in the network services data base,
     /etc/services.

[sorry for posting this little peace of man]
