>Description:
I decided to use ucarp to make redundant firewalls, and I noticed that there was no startup script included. You have to start by hand, and it cannot start at boot.
>How-To-Repeat:
portinstall ucarp ;)
>Fix:
The provided patch is a rc.d script (this is my first one for a BSD)
the ucarp stuff I use in rc.conf :
~> grep ucarp /etc/rc.conf
# ucarp stuff
ucarp_enable="YES"
ucarp_src="192.168.30.228"
ucarp_addr="192.168.30.231"
ucarp_if="bge0"
ucarp_upscript="/home/nico/ip-up.sh"
ucarp_downscript="/home/nico/ip-down.sh"
But there is a bit more possible (due to the fact that ucarp has no configuration file)
