You can always use TCPDUMP or WINDUMP to observe traffic. If you are needing to do this from a single PC with Windows you can download WINPCAP and WINDUMP from http://netgroup-serv.polito.it/netgroup/tools.html. If you have Linux you can use TCPDUMP which is installed by default on a lot of platforms. WINDUMP is a Win32 port of TCPDUMP so the command line is pretty much the same. You can pass these tools specific filters to watch certain traffic. For instance, if you have a pc at home that does not offer services to other computers on the Internet such as a web server, etc. You can watch unsolicited traffic and begin to see patterns. I was using this when blaster was born and knew right away there was a new worm. So, if you want to watch traffic on your home pc you can: (read the manual on how to get your adapter) Windump -tnn tcp[13]==0x02 and dst host your.ip This line above will give you all TCP connection requests heading TO your ip address and has the SYN flag set which indicates a new connection request.
