Xip is a “human ip stack”. It acts like tcpdump(8) but with the possibility of changing packet values, creating packets and sending them. It displays packets ala “Steven’s book”. It has been designed in C language and in an object-like fashion. Everythingwas made up to increase speed. It is configurable and extensible by adding plugins. Currently, it supports (nearly) all the protocols described in “Stevens book”. But there is some more work to do on it.
