Using a Command-Line Sniffer

Sometimes you need a sniffer with a little less overhead. A command-line sniffer has less to process and will place less of a load on the system you are running it on. Sometimes you might be in a situation where you only have console (command-line) access and can't use a GUI tool. At these times a command-line sniffer might be able to provide the sneak peek into the network traffic you're looking for. I will briefly explain the use of a few command- line sniffers. One of them will require the WinPcap drivers, the other does not if you are using it on a Windows 2000 or newer operating system, and the last is a Linux command-line sniffer.
