Here ya go
Provided you have netcat installed, this should run pretty quickly.

Code:
for port in {1..65536}; do
    nc -zv 127.0.0.1 $port 2>&1
done | grep open

Netstat will also tell you what programs have open listening tcp ports. On a linux system, it would go something like this:

Code:
netstat -l -t -p
