Description:

NetSED is small and handful utility designed to alter the contents of
packets forwarded through 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 - choose whatever you want to.
