1. The network packet altering stream editor NetSED is small and handful utility designed to alter the contents of packets forwarded thru your network in real time. It is really useful for network hackers in following applications: * black-box protocol auditing - whenever there are two or more proprietary boxes communicating over undocumented protocol (by enforcing changes in ongoing transmissions, you will be able to test if tested application is secure), * fuzz-alike experiments, integrity tests - whenever you want to test stability of the application and see how it ensures data integrity, * other common applications - fooling other people, content filtering, etc etc - choose whatever you want to. It perfectly fits ngrep, netcat and tcpdump tools suite. From Debian 3.0r0 APT
