[AdBlock] Which trigger to reload lists?

Installing and Using OpenWrt
1

Hello,
i've just found out that my adblock instance reloads every 30 seconds. I was getting mad to understand why my dns calls failed now and then.. well, that's it.
I configured it, as i assume is commonly done, with a trigger on my wan interface (dhcp6 interface). Well, it seems this interface has an ifupdate event every 5 minutes. So, my question: assuming it's not viable to keep adblock to reload every 5 minutes (killink dnsmasq) what should be the correct way? it seems adblock can't filter the event (for example waiting only for ifup events), so what should i do?
thanks

Provide your adblock config and the output of /etc/init.d/adblock status

it is really something connected to the wan6 interface.
Here is my config, i've now set the trigger interface to the wan_dhcp6_4 interface (that is a virtual interface created by the map package!) since the "real" interface (wan_dhcp6) has this event every 5 minutes

Nope, adblock only responds to ifup events, e.g. the relevant excerpt from the init script:

	for iface in ${trigger}; do
		procd_add_interface_trigger "interface.*.up" "${iface}" "${adb_init}" start
	done

Avoid WAN6 interfaces ... IMHO it's an old odhcpd v6 bug.
Use WAN4 or LAN4 instead.

not good to know :frowning:

well that's what i'm trying to do with the MAP interface, but it's virtual, my only wan interface is a dhcpv6 interface..
just wondering: why adblock is connected to interface going up and down? isn't it a matter of updating list? so a cron task shouldn't be better?

Than bin the trigger and add a cron reload, see the online readme.
