AttributeError: 'Namespace' object has no attribute 'opc_afl'

[kburova]

I tried to run shellphuzz after a long and painful installation of fuzzer and driller with all the prereqs for python 3 on Ubuntu 16.04 and got this: [*] Creating fuzzer... Traceback (most recent call last): File "/home/kburova/.virtualenvs/devis/bin/shellphuzz", line 87, in <module> memory=args.memory, seeds=seeds, timeout=args.run_timeout, protocol_fuzz=args.opc_afl, AttributeError: 'Namespace' object has no attribute 'opc_afl'

I removed protocol_fuzz=args.opc_afl, form this line:

fuzzer = fuzzer.Fuzzer( args.binary, args.work_dir, afl_count=args.afl_cores, force_interval=args.force_interval, args.binary, args.work_dir, afl_count=args.afl_cores, force_interval=args.force_interval, create_dictionary=not args.no_dictionary, stuck_callback=stuck_callback, time_limit=args.timeout, create_dictionary=not args.no_dictionary, stuck_callback=stuck_callback, time_limit=args.timeout, memory=args.memory, seeds=seeds, timeout=args.run_timeout memory=args.memory, seeds=seeds, timeout=args.run_timeout, protocol_fuzz=args.opc_afl, )

to make it work, but I'm not sure if that's the best solution.

AttributeError: 'Namespace' object has no attribute 'opc_afl indicates that there's something wrong with your python environment. When I see that it usually means I have a folder in my current directory which is shadowing the import of some module. If this doesn't seem to be the case, can you run the script with ipython --pdb to get a debug shell and print out the value of args?

I dont see opc_afl being added to the args parser in the script itself...

Yeah okay. I'm not sure what the heck that line was about. I've removed it.
