dear budsz,
 Trinoo Master and a several "unknown" port will appear, even you never set
before. This symptoms will happen if you are using ipfw with "default to
deny" policy or using an IDS tools like snort or portsentry. But, this
symptoms only appear if you are using nmap portscanning tools. I have the
same experience, but i just ignore it..:) except a several port like
telnet,ssh and ftp.
Nmap trying to conduct a tcp "half-open" connection to all tcp port, from a
smallest port to several hundred ports ,so nmap try to give you the best
"answer" altough the answer is confusing...:).
I suggest you to try using another portscanning tools to compare the result.
