Sniffer Cable Pinout

The sniffer cable is needed to connect a sniffer to an ethernet┬áhub, but not transmit any data that may reveal the sniffer’s existence. This cable will return an inverted version of anything sent to the interface. The pinout for this cable is from the book Windows Forensics, by Chad Steel (ISBN 0-470-03862-4), but can also be found at dgonzalez.net, along with other useful pinouts for receive-only cables.
