sniffit 0.4.0-4 (amd64 binary) in ubuntu disco

 Sniffit is a packet sniffer for TCP/UDP/ICMP packets over IPv4. It is able
 to give you a very detailed technical info on these packets, as SEQ, ACK,
 TTL, Window, etc. The packet contents also can be viewed, in different
 formats (hex or plain text, etc.).
 .
 Sniffit is based in libpcap and is useful when learning about computer
 networks and their security.
