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 propertiary 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.
