thats just "normal" list of ports
you can asign anything to any port
as u can have a proxy server running on port 80 witch is also the httpd default port
and going off that method, the scanner would think that some1 running a home webserver has an open proxy server running and would ban that ip with its just a httpd running,
what i want to know is if there is a command to send to the ip:port to get header information, so it will reply with http>
etc etc
so it can tell if its a normal service or a proxy server
