OpenBSD setup

Building the binary

Binary needs to be compiled for OpenBSD OS.

git clone <reaction git repo>
cd reaction
GOOS=openbsd make reaction

Service

To use reaction as service on OpenBSD, you will need to create a new file on /etc/rc.d/ which will define your service, such as :

#!/bin/ksh

daemon="/usr/local/bin/reaction"
daemon_flags="start -c /root/reaction.conf"

. /etc/rc.d/rc.subr

rc_reload=NO
rc_bg=YES

rc_cmd $1

Then you need enable it with rcctl enable reaction.

Configuration

Configuration differs from regular linux one as OpenBSD uses PacketFilter instead of iptables/nftables. Also, OpenBSD configuration doesn't need the additional ip46tables binary, and can be fully setup from configuration file.

A configuration exemple is present here.

To infinity and beyond

After configuring your instance and setting up your service, you can now enjoy it by running rcctl start reaction.
