First time to post on these forums, have been an avid reader of these forums, just wanted to know what are the best or what would everyone recommend out there as far as Network Monitoring tools, Kinda like a big brother kind of a thing or one that gives you tons of information.. Any help would be appreciated...

You mean packet logger? Try Ethereal.

Ethreal is the only tool i would use for network analysis. I have used it before for packet analysis (like an Agilent LanMonitor) to analyse the packet headers and determine the traffic content contained in the packets (am an Electronics Tech and had to show the different packets traveling on the college networks. Showing MAC addresses etc contained in the packets).

It works on Windows, *nix etc and is completely free. It contains so much that it might take a while to learn properly, but I do know that many hackers/crackers (depending on the word you use for those who break into computers or use data from captured packets fro fraud) use this all the time
