Running in Parallel

We have a nice optimized fuzzer now, but we still want to get our fuzzing done faster and it just so happens we have a couple extra machines sitting around just begging to be used for fuzzing. Luckily Peach supports parallel fuzzing, and it's super easy. All we need to do is add a single command line argument and run our fuzzer on each machine. Here is how we do it:

1. Configure Machines

First we need to configure each machine to have:

1. Peach
2. Target application

3. wav.xml

2. Run Peach

Next we just run the fuzzer on each machine. We can launch peach using this syntax:

Machine #1

c:\peach\peach.py -p3,0 wav.xml

Machine #2

c:\peach\peach.py -p3,1 wav.xml

Machine #3

c:\peach\peach.py -p3,2 wav.xml

Notice that we are adding an argument "-p" to the command line with two numbers. The first number indicates the total number of machines we will use and is 1 based (counting starts at 1). The second number indicates the machine we are running Peach on. This number is zero based (counting starts at 0, 1, 2, 3...).

EASY!
