NAME

Net::OpenVPN::Launcher - start, stop and restart OpenVPN as a sub-process.

SYNOPSIS

    use Net::OpenVPN::Launcher;

    my $pm = Net::OpenVPN::Launcher->new;

    $pm->start($filepath_to_config_file);

    # do some stuff

    # now stop the first instance of OpenVPN and start another
    $pm->start($filepath_to_alt_config_file);

    # do some stuff

    $pm->stop;

DESCRIPTION

Net::OpenVPN::Launcher is an object oriented module that provides methods to start, stop and restart OpenVPN. It's useful because it runs OpenVPN processes as a non-blocking sub-process. This allows you to start and stop several OpenVPN processes within the same Perl program.

SYSTEM REQUIREMENTS

  • OpenVPN needs to be installed and in $PATH (or in bin, in $PATH).

  • This module has been tested on OpenVPN version 2.2.1 - it should work with most versions of OpenVPN.

  • Currently only works with Linux-like operating systems.

  • By default OpenVPN needs to be run with root privileges, hence any Perl program using this module will need to be run as root unless OpenVPN has been configured to run under user privileges.

METHODS

start

Initialises OpenVPN with a config file. Requires a filepath to an OpenVPN config file. See the OpenVPN documentation for example config files and options.

    $pm->start('openvpn.conf');

restart

Restarts the existing OpenVPN process with the same configuration file as before.

    $pm->restart;

stop

Kills the OpenVPN process.

    $pm->stop;

INTERNAL METHODS

DEMOLISH

This method is called on object destruction and it will call the stop method if any active openvpn processes are found. This means it is not necessary to call the stop method when exiting the program.

config

This is a getter/setter method for the filepath to the OpenVPN configuration file.

openvpn_pid

This is a getter/setter method for the PID of the openvpn process.
