mwan3-notify

Get yourself a notification straight to the laptop when some mwan3-managed network is down.

/etc/mwan3.user (cgi-bin/luci/admin/network/mwan/notify):

#!/bin/sh

SECRET="xxx"

/usr/bin/curl --insecure \
	--data-urlencode "hostname=${HOSTNAME}" \
	--data-urlencode "action=${ACTION}" \
	--data-urlencode "interface=${INTERFACE}" \
	--data-urlencode "device=${DEVICE}" \
	--data-urlencode "secret=${SECRET}" \
	"https://mwan3-notify-addr.a/mwan3-notify" \
	-o /dev/null >/dev/null 2>&1

nginx.conf for 443 (and reload):

        location /mwan3-notify {
            fastcgi_pass unix:/run/mwan3-notify-fcgi/fcgi.sock;
            include fastcgi_params;
        }

/etc/tmpfiles.d/mwan3-notify.conf:

d /run/mwan3-notify-fcgi 0755 <your-user> <your-group> -

create the sock dir:

sudo systemd-tmpfiles --create

make
sudo cp bin/mwan3-notify-fcgi /usr/local/bin

test by hand:

/usr/local/bin/mwan3-notify-fcgi -s xxx -i /usr/share/icons/gnome/32x32/emblems/emblem-new.png &
curl --insecure --data-urlencode "hostname=a" --data-urlencode "action=b" --data-urlencode "interface=c" --data-urlencode "device=d" --data-urlencode "secret=xxx" "https://127.0.0.1/mwan3-notify"
