e185698445 Use current system resolvers as default 
That makes more sense that putting French servers.

What is in /etc/resolv.conf is not always good, but most of the time it's the hoster's or something nearby. Thus it makes more sense for the user to use them by default.

19fe6626f1 Implements OpenVPN 2.4 changes for Arch Linux (kind of) 
Since OpenVPN 2.4 is out on Arch, the script wasn't working completely because of this : https://www.archlinux.org/news/openvpn-240-update-requires-administrative-interaction/

There is a new path for OpenVPN server config. This is just needed on Arch for now, and you're probably not going to run an OpenVPN client on an OpenVPN server. 

Thus I modified the systemd script to use `/etc/openvpn/` and `server.conf` instead of the new `/etc/openvpn/server/` and `openvpn.conf`.

By using the same paths as the other distros, I avoid to rewrite the entire script to change the paths...

It's not 100% clean, but it works pretty well. If you have any objection please leave a comment.

Also, I updated the new service name.

As far as I tested, it's working fine on Arch Linux for now.

Fixes #63 and #61

ac203dd5ee Fix iptables rules on reboot for some OS 
Thanks a lot to Nyr for the fix : a31aaf82f3

Fixes https://github.com/Angristan/OpenVPN-install/issues/6.

On Ubuntu 17.04, 16.10 and Debian 9, the iptables rules were not applied because of rc.local

7a5bb93cbe AES-256 is not necessarily the most secure cipher 
Indeed, it it most vulnerable to Timing Attacks : https://en.wikipedia.org/wiki/Length_extension_attack

Also, AES 128 is secure enough for every one, so it's still the recommended cipher.

56477bba34 The crypto update 🔐 
- Removed "fast" and "slow" mode (not a good idea, I prefer to give the choice for the parameters directly)
- Corrected some confusion between the cipher for the data channel and the control channel, my bad.
- using TLS-DHE-RSA-WITH-AES-256-GCM-SHA384 by default for the control channel
- using SHA384 by default for HMAC auth and RSA certificate
- giving the choice for the cipher of the data channel, the size of the DH key and the RSA Key

I will explain all my choices here : https://github.com/Angristan/OpenVPN-install#encryption (likely tomorrow)

9aeb5b7c47 Remove old fix 
This fix was intended to overcome hardcoded buffers values in old OpenVPN revisions (see https://www.lowendtalk.com/discussion/40099/why-openvpn-is-so-slow-cool-story). This is not needed anymore, as OpenVPN now use OS buffers (see https://community.openvpn.net/openvpn/ticket/461 and https://community.openvpn.net/openvpn/changeset/c72dbb8b470ab7b25fc74e41aed4212db48a9d2f/). It should lead to better performances over fast networks.

eb8d8257a0 The BIG commit 
- Upgrade to easy-rsa 3.0.0
- Firewall support: rules are added for both FirewallD and iptables if
needed.
- Creation of our own configuration files for both the server and
clients.
- Using subnet topology instead of the deprecated net30.
- Removed port 53 question during install: user can just choose that
port during setup.
- Removed internal networking option: this is a road warrior installer
after all.
- Bugfix: the default easy-rsa directory was not correctly deleted if
one was already there.

ee9750a210 Use Easy-RSA 2.2.2 instead of the master branch with Debian Jessie and Ubuntu Saucy 
This was needed for Debian Jessie, but using always the latest Easy-RSA
was a bad idea.

I will force Easy-RSA 2.2.2 for now and until Jessie becomes stable.
Then we can probably just use the distro packages instead of Github,
but for now this will work.
