In a local network :
1) How can I get all availabe IP addresses?
2) How can I find out which one is active and which deactive?
3) How can I sniff (like Linux) around and see what ports are being used. The reason I'm asking this one is because I know there are some emplyees that use a networking game among themseleves and need to see which port they are using and how can I interrup it?
No, I'm not the employer. I just want to see if there is a way using some tools to interrupt the connection or something like it.
ASKER CERTIFIED SOLUTION
It seems there was misunderstanding, maybe because I didn't explain it well.
I don't want to report it or cause any problem, not at all !
I was thinking of a way to learn this method of how to sniff in Windows.
Thanks to all for your advices.
