Description

netsed is a small utility designed to allow you 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 - whenever there are two or more proprietary boxes communicating over an undocumented protocol (by enforcing changes in ongoing transmissions, you will be able to test whether the tested application is secure) * fuzz-alike experiments, integrity tests - whenever you want to test the stability of an application and see how it ensures data integrity * other common applications - fooling other people, content filtering, etc. -- choose whatever you want to It fits well with the ngrep, netcat and tcpdump tool suites.
