How to Threading a socket connection to all TCP ports?

• Hi, When you create a socket connection to scan all (65535) TCP ports to ensure if they are open or not, the connection to all ports is really time consuming (at least taking hours to complete, if even it may stop). I was thinking threading some of the socket connections in groups (dividing 65535 into a separate groups) to increase the speed of scanning all ports. How can I get around doing this? Thanks

• Answer:

  Are you trying to scan a destination (a target pc, for example) or a path (to see if your pc can reach the Internet without being blocked by a firewall)? If a path, then try http://www.firebind.com It can scan all 65535 UDP and TCP ports between your machine and the Internet to determine if a given port is open or blocked.
