I wish there was an afl-fuzz like tool for fuzzing network traffic. By afl-fuzz for network traffic I mean a general purpose network fuzzer; not protocol specific fuzzer like the codenomicon ipsec fuzzer. Does anyone know of anything close? Remotely close?<p>There seems to be a significant overlap in what you would want from a network protocol fuzzer and a tool to reverse engineer a network protocol. Netzob is the only protocol RE tool that I know of and it seems that development has stalled.
I don't see why afl-fuzz needs to be turned into a general-purpose Swiss Army Knife framework. It excels quite well at mutation-based techniques that train themselves on resulting outputs. For problems that involve specifically triggering code branches, then a tool that employs symbolic execution methods via constraint solving should be used instead, as the author implies.
