Error using Afl-proxy.c program

[Aoife Mc Daid]

Hi all, 

I am trying to use the afl-proxy.c script to fuzz my target program, am I correct in saying the whole program should be fuzzed using the following command:

afl-fuzz -i /input -o /output -- ./afl-proxy.c

However when the fuzzer runs I am getting "last new find: none yet (odd, check syntax!)".

Any suggestions on how I can fix this?

Kind regards,

Aoife

you have to modify afl-proxy to talk to your target whatever that is.
you cannot use it out of the box.

if you look at the source it tells you where to add necessary code.
