Port multiplexing
Port complex is on an open port, the information input by matching the character to run different services. Port multiplexing only character information input matching network does not intercept any data, copy type operation, the transmission performance of the network data unaffected. Port multiplexing is often used by hackers to make the back door. In the implementation of winsock, for server bindings are bound to be multiple, multiple bindings use in determining who, when, according to a principle of who is most clearly specify who will be submitted to the package, and there is no permission of the points, that low-level user permissions can be re-bound to the port authority advanced user-initiated, which is a very significant security risk.
Port simple implementation of multiplexed
This script is a TCP port complex, the use of python3 development, when you run the script, you access the specified port, the script will automatically route your traffic will be forwarded to the for the route. The project is a script on github.
Access to the target host port 2222, the script will automatically routed to port 80
Access to the target host port 2222, the script will automatically routed to port 3389
Access to the target host port 2222, the script will automatically routed to port 22
