My graduation design this year is a local area network monitoring system, which requires no software to be installed on other computers, and other computers to be monitored on this machine, but now I do n’t know how to program and implement MSN and other instant messaging tools. If you know, give me the source code Or give some ideas, thank you very much

Monitor the process and find that the process of QQ or MSN ends immediately
But it is not clear whether this is possible on the Internet.

However, what I want is to be able to implement this function on my own computer, that is, on any machine on the LAN, as long as this software is installed, you can monitor the condition of all other machines, such as whether it is in use QQ.MSN, and can block their QQ / msn.

In addition, I also want to prohibit other machines from accessing the Internet. I think this way: If my computer is A, the machine I want to ban on the Internet is B, and the gateway is G, then I can disguise myself by sending a fake ARP packet to G. B, then the data packet that G originally sent to B is now passed to me. By this, B can be banned from accessing the Internet.

But now the question is: by disguising as B, all the data that G sends to B is sent to me, so can B not be able to go above QQ / MSN, that is, can B be unable to contact the outside world?

Everyone has good suggestions to say, my graduation design came.
