dietsniff is a tiny tool for analyzing traffic on
a network. It's not intended to replace well-known
tools like tcpdump or ethereal. It's intended for
the case when a small and especially static
sniffer is required. Accordingly, it's also by far
not that powerful, and is also bound to Linux as a
platform. While it doesn't use or need the
libpcap, it produces pcap-logs that can be
analyzed by more sophisticated tools like tcpdump
or Ethereal.
