I ran an nmap scan on my mac68k 1.4.2 machine and got these strange
results (the actual command was nmap -v -O):

Interesting ports on kenny:
Port    State       Protocol  Service
22      open        tcp        ssh
137     filtered    tcp        netbios-ns
138     filtered    tcp        netbios-dgm
139     filtered    tcp        netbios-ssn
1080    filtered    tcp        socks

Remote operating system guess: NetBSD 1.3I (after 19990119) or 1.3.4

I say strange because I'm not running Samba (which I assume uses those
netbios-* services), and I'm not altogether sure what socks is.  Port 22
is the only one I expected to see in the results; netstat -an shows
nothing on ports 137-9 and 1080.

Is this just a quirk of nmap?  If not, how do I close off these ports?

Thanks.
