dietsniff is a tiny tool for analyzing traffic on a network. It is not intended to replace well-known tools like tcpdump or ethereal. It is intended for the case when a small and especially static sniffer is required. Accordingly, it is also by far not that powerful, and is also bound to Linux as a platform.
