net/netsed 1.4 FreeBSD

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 the following applications:

* Black-box protocol auditing -- if there are two or more proprietary boxes communicating over undocumented protocol (by enforcing changes in ongoing transmissions, you will be able to verify that 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.
