What open ports?

This is a TCP / UDP report about the PC-BSD machine on our local net, portscanned using nmap(1) from the server (sorry for not in HTML -tt- mode):

% nmap -sT -sU -O 192.168.1.40
Interesting ports on 192.168.1.40:
(The 3107 ports scanned but not shown below are in state: closed)
Port State Service
22/tcp open ssh
137/udp open netbios-ns
138/udp open netbios-dgm
139/tcp open netbios-ssn
445/tcp open microsoft-ds
514/udp open syslog
631/tcp open ipp
631/udp open unknown

It really looks strange to me. Of course, an open ssh port is really NO problem.

This is my PC-BSD 1.3B1 firewall and I selected only port 22 (SSH) for connectivity in installer- by default all ports are closed.

Really? Is PF (or IPFW) enabled by default? Seems that someone has to review his configuration... :-)

Of course you can open/close your favorite ports if you wish.

Of course you can, it's a BSD. :-)

Now I understand the "problem", it shows ports, but you can't actually connect to- your connection would be dropped...
