Where do I get OpenVPN config file?

I have an application on a linux server. The application makes regular requests to a specific server, and I would like to set up a VPN so that all the requests to the server will go over this VPN instead of the standard internet connection.

It looks like OpenVPN will do this, but I don't know how to obtain a configuration file to work with. Can you please help me? Thanks. I'm not familiar with any particular VPN program, but it looks like OpenVPN uses a PEM-encoded text format for configuration files. This means you'll want to find a way to get your text editor to export the contents as a PEM file. There are a variety of ways to do this, but basically the "right" way is to write your configuration to a file in the standard configuration format (often called "CONF") and then convert that file to PEM using the openssl utility.

For example, in CentOS, you can use: # cat myconfig.conf key -export -out myconfig.p12
Or on a different system, you can do: # openssl pkcs12 -inkey privatekey.pem Once you've got the PEM file, you can use it as a configuration file for OpenVPN.

How do I download OpenVPN configuration files?

You can download the OpenVPN configuration files in either ASCII or binary format. The ASCII format is text, and is easy to read, modify, and use. The binary format consists of raw data, with no surrounding text to allow it to be read or understood by software.

You may also download the OpenVPN configuration files as a tarball. Each file in the archive has a different extension, so you need to browse through all the files to locate the configuration file for OpenVPN 2. For example, this is how to find the configuration file for a CentOS 6.5 system that is using OpenVPN 2.4:

Tar -zxvf openvpn-2.tgz The files in the directory ~/openvpn-2.4 will be the configuration files. The configuration files have the extension .ovpn, and are generally named after the user that created them. For example, the default configuration file is named my-vpn-client.ovpn, but yours may be named something else depending on the user and computer that is configured to use OpenVPN.

Here's an ASCII sample of one configuration file: dev tun. Proto tcp. Remote 127.0.1 443
Resolv-retry infinite. Nobind. Persist-key. Persist-tun. Ca /etc/openvpn/easy-rsa/keys/ca.crt cert /etc/openvpn/easy-rsa/keys/my.crt key /etc/openvpn/easy-rsa/keys/my.key comp-lzo. Verb 3. In the file, the client section states that OpenVPN will listen on port 443 (https), use a protocol of TCP, and will accept and decrypt any type of communication. The remote IP address, 127.1, is the address of the server and client computer (assuming they are on the same network segment). The resolv-retry indicates that OpenVPN will retry if a communication fails. The nobind indicates that the encryption key will not be bound to a specific IP address. The persist-key specifies that any private keys should be kept in memory for future encryption. The CA and certificate fields refer to the certificates and keys that are used for encryption.
