You could use the always old echo in inetd. listening on all ports, you know echo1 echo2 etc etc.. is something you do one time an reuse, only listening where you say as fast as kill -HUP inetd. You can test any port by modifying http://www.cs.cf.ac.uk/Dave/PERL/node182.html script

In the past I would just set up a test box on a test LAN on the external interface of the Firewall and pick a service and run it on whatever port I need to test. I am looking for something more secure and configurable that wont put an actual service out in the open. Hopefully a tool that will allow me to open ports on a windows / or *nix box without actually having a particular service running there. Maybe a banner, or just something that will allow me to determine if the connection was successful. Preferably I would like the ability to open multiple ports at a time and be able to make quick to changes. My methodology is that if I get a positive connection I know the firewall is allowing me through and routing properly. Any recommendations for tools or different perspectives on how to test this will be greatly appreciated! Thanks."Our care should not be to have lived long as to have lived enough.", Seneca
