	# ==============================================================
	# Mount the installer image. It assumes that the installation app is called "Install OS X Yosemite.app"
	# located in your "Applications" folder. If not, change the first command accordingly.

	# you are expected to prepare /System/Library/Kernels/kernel at this stage
	# kernel can be extracted from InstallESD.dmg/Packages/Essentials.pkg/System/Library/Kernels/kernel with Pacifist

	PATH_TO_KERNEL=kernel

	#!/bin/bash

	# Setup encrypted IPv4 tunnel over IPv4 or IPv6 on two Linux nodes using SSH for tunnel setup.
	# Requires only ipsec-tools, iproute2, ssh and necessry kernel modules locally and remotely.

	# Warning: it flushes IPsec settings both locally and remotely.
	# Don't use with other IPsec tunnnels.

	# Sample usage:
	# simplevpn -6 fc::1 fc::2 ssh -T root@fc::2

	# install dvd+rw-tools
	$ sudo yum install dvd+rw-tools
