This works for me. The nmap -g can be used for scanning from the source port and the following can be used to communicate. nc -p 53 127.0.0.1 21 netcat -p <local port> <external ip> <external port> -----Original Message----- From: Jacob Weeks [mailto:jaweeks () gmail com] Sent: Thursday, June 23, 2005 8:58 AM To: chris_perst () gmx de; pen-test () securityfocus com Subject: Re: Connecting to different services with source port 53 just a quick search in google for "telnet source port", came up with some results.. one being http://www.foundstone.com/index.htm?subnav=resources/navigation.htm&subc ontent=/resources/proddesc/fpipe.htm havn't tried it, so i can't say for sure it'll work.

Hi list, I'm pen-testing a system and with a normal "nmap -sS" I get no response.
