apt-get install openvpn
Usage
Create Instance
After including the library with autoloader or manualy, you can initiate and configure the class.
$openvpn = new Paranic\Openvpn();
$openvpn->server_address = '127.0.0.1';
$openvpn->server_port = '1194';
$openvpn->protocol = 'udp';
$openvpn->easy_rsa_folder = '/tmp/easy-rsa';
$openvpn->network = '10.0.0.0';
$openvpn->netmask = '255.255.255.0';
All keys generated will be stored in the easy_rsa/configs folder.
Setup easy-rsa
$openvpn->setup();
This is going to take some time, creating required keys for the first time.
Generate Server Configuration
$openvpn->create_server();
Again your server configuration is stored at easy_rsa_folder under the keys_packed subfolder.
Generate Client Configuration
$openvpn->create_client('sample_client_1');
You can create many clients and get theyr configuration in the keys_packed folder, including a all in one inline client config file.
