# Introduction
It's not uncommon to need to be connected to a bunch of overlapping
VPNs, network namespaces offer an easy way out of that problem.
Additionally user namespaces offer the ability to run a VPN entirely as
a user while still sharing the filesystem with the outside allowing all
your usual commands to work.

Also, it was a fun way to show how easy it is to work with namespaces
using the tools provided alongside LXC.

# How
The start-vpn script creates a new user namespace where your user is
root, then does a few trick so openvpn and byobu can happily run.
openvpn is then started and a byobu server started so you can easily
attach inside the container.

# Dependencies
 * socat
 * openvpn
 * byobu
 * uidmap
 * lxc
 * A 3.13 or higher kernel with usernamespaces enabled

# Using

git clone git://github.com/stgraber/vpn-container
    cd vpn-container
    ./start-vpn \<VPN NAME\> \<VPN CONFIG\>

The vpn name is used for the socket/pid files and for the container's
hostname (so you can easily see what VPN you're working on).

The vpn config is a standard OpenVPN configuration file.
