exdump is a packet watcher, dumper, and logger. TCP, UDP, and ICMP packets which pass a computer which exdump resides on and runs on are logged. exdump allows output to be directed to the console/adm or to a user-defined file. exdump also has an option to only display packets which are sent to a specified port. And, exdump can actually show you the data which was in the packet.
