Weird ports?
 

Why does netstat show these ports which I'm not using?

netstat -atn | grep "LISTEN"
tcp 0 0 *.46709 *.* LISTEN
tcp 0 0 *.21614 *.* LISTEN
tcp 0 0 *.47653 *.* LISTEN

nmap too:

PORT STATE SERVICE
46709/tcp open unknown
MAC Address: 00:************ (3com)

PORT STATE SERVICE
21614/tcp open unknown
MAC Address: 00:************ (3com)

Just to show they aren't all open or something:

PORT STATE SERVICE
46708/tcp closed unknown
MAC Address: 00:************ (3com)

I'm on openbsd 4.0.

Try “netstat -p” to see the process ID using the socket.
