ports security need help
I wrote a perl socket program which listens on 40011 port number the program works fine. But just a question crossed in my mind I tried to find the answer but I didn't find. Please if anyone have the answer or idea please reply...
How to know that which ports are bocked on the UNIX (HP-UX) system?
How to know that the port is already in use so we can avoid its reuse?
Thanks..
