Exploit for Samba vulnerabilty (CVE-2015-0240) by sleepya

The exploit only targets vulnerable x86 smbd <3.6.24 which 'creds' is controlled by 
ReferentID field of PrimaryName (ServerName). That means '_talloc_zero()'
in libtalloc does not write a value on 'creds' address.

# Slightly modified version from https://raw.githubusercontent.com/Nyr/openvpn-install/master/openvpn-install.sh
# Run with sudo ./openvpn-install.sh and not sudo sh ./openvpn-install.sh as read command has issues with external triggering of scripts
# OpenVPN road warrior installer for Debian, Ubuntu and CentOS

# This script will work on Debian, Ubuntu, CentOS and probably other distros
# of the same families, although no support is offered for them. It isn't
# bulletproof but it will probably work if you simply want to setup a VPN on
# your Debian/Ubuntu/CentOS box. It has been designed to be as unobtrusive and
# universal as possible.

This code computes pi. It's not the first python
pi computation tool that I've written.  This program
is a good test of the mpi4py library, which is
essentially a python wrapper to the C MPI library.

To execute this code:

mpiexec -np NUMBER_OF_PROCESSES -f NODES_FILE python mpipypi.py
