I did not really understand your question but maybe you are looking for Ethereal? It is a very good network sniffer which can capture all the packets that come to your network card. Put it into promiscuous mode and it will also capture packets that are not for you. Then you can read each packet and filter the "bad and uninteresting" out.

For monitor network activity use netwatch, it is enough for me.

What you can capture depends on how the network is set up. You can only sniff packets as long as you are behind the same hub as the target. Or, if your box has two interfaces and acts as a router then you can sniff everything passing you.

Just start a sniffer and check what ip addresses you get, then you will see what conversations that you can sniff. I don't know if I can give you more help than that.
