hi
My idea is to use knot resolver as dns forwarder / cache instead using
dnsmasq. I am using old PC with archlinux as router.
I did change dnsmasq config so it listen on port 5353.
following steps here
https://wiki.archlinux.org/index.php/Knot_Resolver
I did change systemd unit so my kresd is listening on both local interfaces. I
am checking that with ss command and it is ok.
here is my config of kresd
cat /etc/knot-resolver/kresd.conf
-- vim:syntax=lua:
-- Refer to manual:
http://knot-resolver.readthedocs.org/en/latest/daemon.html#configuration
-- Load useful modules
modules = {
'policy', -- Block queries to local zones/bad sites
'hints > iterate', -- Load /etc/hosts and allow custom root hints
'stats', -- Track internal statistics
'predict', -- Prefetch expiring/frequent records
}
-- See kresd.systemd(7) about configuring network interfaces when using systemd
-- Listen on localhost (default)
-- net = { '127.0.0.1', '::1'}
-- Enable DNSSEC validation
-- trust_anchors.file = '/etc/knot-resolver/root.keys'
hints.root_file = '/etc/knot-resolver/root.hints'
-- Cache size
cache.size = 100 * MB
After start I can see following errors in journal

thank you for help
Hi,
I am not able to force knot-resolver to forward some queries.
I have real DNS zone and in internal network I have few 3rd level subzones.
For them I would like to make my kresd forward queries to our internal DNS
server (bind9).
My computer is not inside company nework - connected via openvpn.
System is ubuntu 18.04.1 (up-to-date) and knot-resolver 3.0.0.
Relevant part of kresd.conf is:
policy.add(policy.suffix(
policy.FORWARD('10.0.0.1'),{
todname('sub1.company.cz'),
todname('sub2.company.cz')
}
))
dig machine.sub1.company.cz @127.0.0.53 does NOT work,
dig machine.sub1.company.cz @10.0.0.1 DOES work
I have set verbose(true) but with no help.
kresd queries 10.0.0.1 for 'company.cz' only, but that's all.
I am just working on it on my ubuntu workstation,
but real target will be turris omnia with its kresd,
which connects via openvpn to company network.
