ovpn: Convert from servername -> server_url * Previously the server name cached the common name generated during init and assumed always 1194/udp. * The new configuration allows for users to pass in a url in a new form that allows the protocol to be specified as well as the port. * Example: udp://vpn.example.com:1194 * Try to be backwards compatible. 2014-07-01 05:43:00 +00:00			`#!/bin/bash`

env: Re-work environment code * Instead of storing just a server_url which was necessary to regenerate the OpenVPN configs, instead store an env file. * Move all the env parsing to `ovpn_genconfig` so that it can be re-run from genconfig instead of from `ovpn_init`. * Remove all the parsing and env defaults except for genconfig. NOTE: This breaks the older config method, uesrs will need to re-run genconfig with an arg[1] as the previous server_url, this will create the necessary env file the rest of the tools expect. Example recovery for legacy users: host$ docker run --rm -it kylemanna/openvpn bash -l container# ovpn_genconfig $(cat /etc/openvpn/server_url) 2014-07-06 01:51:58 +00:00			`source "$OPENVPN/ovpn_env.sh"`

ovpn_init: Protect the CA key by default * Protect the CA key with a passphrase by default to protect it from a filsystem compromise. An attacker could still steal the other keys stored (ie the server's cert key), but not issue new keys. * This is a good compromise for now. 2014-06-05 00:07:07 +00:00
