#!/usr/bin/sh
/usr/bin/peervpn $* | sed -nue "/warning: could not send packet!/!p"

peervpn@.service

# To create a new PeerVPN instance called <name>, create a new configuration file
# /etc/peervpn/<name>.conf. You can use the provided example configuration file
# peervpn.conf as a template.
# 
# After the configuration file is created, you can control the instance with
# systemctl using systemd unit named peervpn@<name>.service.
