I know how to use a packet sniffer and I know that it can give me an idea of what is going on across my network. I have seen that there are programs that will take the packets that I log with my packet sniffer and then complie them to see what the files that are being transferred. Can anyone tell me what some of those prgrams are I had a teacher when I was in college use one and demonstrated it to the class but would not tell us what the program was and just told me to Google it. I have tried to Google it for a couple of years now but have yet to find anything that worked the same way. Can anyone out there help me out on this?
