How to install python PaiMei on Mac OSX Snow Leopard
PaiMei, is a reverse engineering framework consisting of multiple extensible components. The framework can essentially be thought of as a reverse engineer's swiss army knife and has already been proven effective for a wide range of both static and dynamic tasks such as fuzzer assistance, code coverage tracking, data flow tracking and more.
Install VirtualEnv
Usually I use VirtualEnv to separate various Python lilbrary installation.
$ easy_install virtualenv
Create Python2.5 virtual environment
I named this virtualenv "debuggerenv25"
$ virtualenv --python=python2.5 debuggerenv25
Every time you open a terminal and you want to use a virtual environment you need to do:
$ source bin/activate
Install PaiMei
Now you need to checkout PaiMei from SVN:
$ svn co http://paimei.googlecode.com/svn/trunk/MacOSX MacOSX
Now you nedd a little patch do made it work. Edit the file pydbg\my_ctypes.py:
- c_types = (Structure, c_char, c_byte, c_ubyte, c_short, c_ushort, c_int, c_uint, c_long, c_ulong, c_longlong, \
+ class Structure2(Structure):
+ pass
+
+ c_types = (Structure2, c_char, c_byte, c_ubyte, c_short, c_ushort, c_int, c_uint, c_long, c_ulong, c_longlong, \
Leave PaiMei and go on installing all its requirements
Install ctypes
Download from sourceforge:
You need to make a change to make it compiling on "Snow Leopard". Edit file ctypes-1.0.2/source/libffi/fficonfig.py.in and change the row 33:
- all_darwin = ('X86_DARWIN', 'POWERPC_DARWIN')
+ all_darwin = ('X86_DARWIN', )
Now you can install it:
python setup.py build
python setup.py install
Install wxPython
Download from sourceforge:
wxPython2.8-osx-ansi-2.8.10.1-universal-py2.5.dmg
and install it with package.
Install MySQL
PAY ATTENTION: YOU NEED TO INSTALL THE 32bit VERSION!!!
Download the 32bit Mysql version for Mac from here:
Install the package and then drag the MySQL.PrefPane file on your Library/PreferencePane Then go to System Preference and start Mysql
Finally add /usr/local/mysql/bin to environment variable PATH (.bash_profile if you use bash)
Install Mysql-Python
Now download Mysql-Python from here:
Before install edit site.cfg
threadsafe = False
Install libdasm
Download and install libdasm from here:
python setup.py build_ext
python setup.py install
Procmod group
sudo chgrp procmod debuggerenv25/bin/python2.5
sudo chmod 2755 debuggerenv25/bin/python2.5
To study in deep this, google for mach kernel security setting and kern.tfp.policy
Add pythonw to virtual environment
Create this two files:
pythonw.c
/*
* This wrapper program executes a python executable hidden inside an
* application bundle inside the Python framework. This is needed to run
* GUI code: some GUI API's don't work unless the program is inside an
* application bundle.
*/
#include <unistd.h>
#include <err.h>
static char Python[] = PYTHONWEXECUTABLE;
int main(int argc, char **argv) {
argv[0] = Python;
execv(Python, argv);
err(1, "execv: %s", Python);
/* NOTREACHED */
}
install_pythonw.py
#!/usr/bin/python2.5
import os
from os import path
import shutil
from subprocess import call
import sys
USAGE = """
Usage: install_pythonw.py ENVPATH
"""
def main(env_path, script_path):
# If Python.app already exists, exit.
python_app_dest = path.join(env_path, 'Python.app')
if path.exists(python_app_dest):
print python_app_dest, 'already exists; exiting.'
return 1
# Find pythonw.c in script path.
pythonw_c = path.join(script_path, 'pythonw.c')
if not path.exists(pythonw_c):
print pythonw_c, 'does not exist; exiting.'
return 1
# Find .Python symlink.
dot_python = path.join(env_path, '.Python')
if not path.exists(dot_python):
print dot_python, 'does not exist; exiting.'
return 1
# Find symlink source.
dot_python_src = os.readlink(dot_python)
if not path.exists(dot_python_src):
print dot_python_src, 'does not exist; exiting.'
return 1
# Find Python.app in PARDIR/Resources/
python_app_src = path.join(
path.dirname(dot_python_src), 'Resources', 'Python.app')
if not path.exists(python_app_src):
print python_app_src, 'does not exist; exiting.'
return 1
# Copy Python.app to env_path
shutil.copytree(python_app_src, python_app_dest)
# Change install names in Python.app binary.
pythonw_executable = path.join(
python_app_dest, 'Contents', 'MacOS', 'Python')
call([
'install_name_tool',
'-change',
dot_python_src,
dot_python,
pythonw_executable,
])
# Compile pythonw to bin directory.
pythonw_dest = path.join(env_path, 'bin', 'pythonw')
call([
'cc',
'-DPYTHONWEXECUTABLE="' + pythonw_executable + '"',
'-o',
pythonw_dest,
pythonw_c,
])
if __name__ == '__main__':
if len(sys.argv) != 2:
print USAGE
sys.exit(1)
env_path = path.abspath(sys.argv[1])
script_path = path.abspath(path.dirname(sys.argv[0]ÿ
sys.exit(main(env_path, script_pathÿ
Then execute install_pythonw.py passing as argument the path of the virtualenv debuggerenv25. In this way you add pythonw bin to virtual enviroment becouse it's needed to start Paimei console.
install_pythonw.py debuggerenv25
Completed. Now you can use PaiMei
Use sudo to start python if you have problem with normal execution. To start console go to PaiMei and run:
sudo pythonw console/PAIMEIconsole.pyw
