Vpn client
OPENVPN CLIENT HOWTO
Our vpn is accessible from the wireless DMZ. Which means in order to connect you have to be logged in to our local wireless network.
In this HOWTO I will cover what you will need to get connected to our vpn, which is simpler then one would think!
Installing the proper software
on a debian system this is as easy as install openvpn, and it's dependencies. We will also intall openssl, something apt doesn't install when installing openvpn. So on a debian based system type:
apt-get install openvpn openssl
and it's done.
on gentoo:
echo "net-misc/openvpn ssl examples" >> /etc/portage/package.keywords/common
then install with:
emerge openvpn
Setting up the Service
We are using a routed vpn, which requires use to use the TUN kernel device, which allows use simulate a network layer device. must distributions that ship a packaged kernel come with this support. To build it in the kernel you have to make sure that it is enabled either built-in or as a module.
A command that you could check this with is:
grep CONFIG_TUN /usr/src/linux/.config
please take the to add kernel support for this by recompiling your kernel, or installing it otherwise.
