Dnsmasq local domain issue

m3m3nto · October 1, 2016, 2:03pm

Hello all,
I found strange behavior with dnsmasq service.
I’ve added a fake domain entry like this in /etc/config/dhcp:

config domain option name 'mylocalfakedomain.test' option ip '192.168.10.217'
dnsmasq reads it’s configuration from /var/etc/dnsmaq.conf, that is an auto-generated config file from /etc/config/dhcp.
If I try to ping mylocalfakedomain.test from Turris Omnia or from any host in my lan it not resolves as expected.
Dnsmasq configuration has “expand-hosts” option activated and if I try to add

192.168.10.210 mylocalfakedomain.test

to the Omnia /etc/hosts, it resolves correctly from the router, but not from other hosts in my lan.
Have you got any suggestions?
Thanks a lot for your help!

Lorenzo

The /etc/hosts file is machine only.

Put:
option port '53535':
into section:
config dnsmasq
of:
/etc/config/dhcp

Put:
list include_path "/etc/unbound/lan.conf"
at the end of:
/etc/config/unbound

Put:

server:
domain-insecure: "loc."
private-domain: "loc."
do-not-query-localhost: no
stub-zone:
name: "loc."
stub-addr: "127.0.0.1@53535"
server:
domain-insecure: "0.0.10.in-addr.arpa."
local-zone: "0.0.10.in-addr.arpa." nodefault
stub-zone:
name: "0.0.10.in-addr.arpa."
stub-addr: "127.0.0.1@53535"

into:
/etc/unbound/lan.conf

Restart dnsmasq and unbound. Basicly there are two dns server on Turris, dnsmasq and unbound. The local domains are added to dnsmasq, but the dns server you have avaiable in local network is unbound. This will connect unbound to dnsmasq for resolving local domains.

Hi and thanks for your reply.
Unbound doesn’t start because kresd instead is active.
It seems that we have 3 dns - kresd, unbound and dnsmasq - installed.
To solve my issue i have stopped kresd and changed dnsmasq port to 53.
It would be very interesting to understand why we ha have 3 dns installed out of the box
Thank you!

@m3m3nto I have the same problem. Is everything running smoothly now? Or do you have any news on your problem?

m3m3nto · October 5, 2016, 9:47am

@protree it seems that everything is ok with only dnsmasq running

protree · October 5, 2016, 4:24pm

How did you disable kresd permanently? LuCl -> System -> Startup says kresd is diabled, but it still starts on boot, preventing dnsmasq from starting…

m3m3nto · October 5, 2016, 4:36pm

@protree yes even if you disable it’ll restart on next boot; I’ve uninstalled kresd service

protree · October 5, 2016, 6:59pm

Got some more info: Either unbound or kresd is launched by /etc/init.d/resolver (See option prefered_resolver in /etc/config/resolver). /etc/init.d/resolver can’t launch dnsmasq, but disabling this script prevents kresd and unbound from launching and allows us to use dnsmasq as our dns-resolver on port 53.

einar · October 8, 2016, 6:41am

For the record, kresd can be configured to read /etc/hosts:

https://knot-resolver.readthedocs.io/en/latest/modules.html#static-hints
https://knot-resolver.readthedocs.io/en/latest/daemon.html#configuration

(Disclaimer: I just skimmed the docs).

ChrisPHL · October 9, 2016, 6:31pm

I was able to solve that issue by simply changing the port for kresd to something else than 53 (/etc/config/resolver).

config resolver 'common'
option port '153'

I even changed/added the port for dnsmasq to 53 (/etc/config/dhcp)

config dnsmasq
option port '53'

This way there’s no need to uninstall the service. So in case an explaination why there are three DNS’s installed gives any clue reverting the changes is something less then in case of remove.

horada · November 5, 2016, 8:38pm

If I remember it correctly from the original Turris, dnsmasq was not used because it didn’t support DNSSEC validation. That was the reason for using unbound (in the original Turris) and it is probably the reason for using Knot in Omnia.
So if you’ll disable Knot and use just dnsmasq, you will lose the advantage of DNSSEC validation for all devices in your network.

Big_boss · November 7, 2016, 11:17pm

I just searched on the web and apparently dnsmasq now a days does support DNSSEC. However, it depends on what version is installed.

http://www.thekelleys.org.uk/dnsmasq/CHANGELOG

Could somebody post what version of dnsmasq is installed on the Omnia?

horada · November 8, 2016, 6:38am

# opkg list-installed | grep dnsmasq
dnsmasq - 2.73-1

Big_boss · November 8, 2016, 7:48am

That explains a lot.

http://www.thekelleys.org.uk/dnsmasq/

The latest so far is dnsmasq 2.76 (released 18-May-2016), while 2.73 was released 14-Jun-2015 Although 2.73 already supports DNSSEC, but a bug-fix is been added regarding DNSSEC in version 2.74.

I think my issue is related to this thread, my apologies if it’s not.

Out of the blue, some wireless internet connections went down for no apparent reason.

I post the system logs here (sorry, I’m not able to figure out where the error is)

I could nevertheless identify a clear error in dnsmasq so a quick search brought me here. I just change the DNS server port from 53 to 0 and I the DHCP leases came back.

Any ideas about what caused the problem?

In the file /etc/config/resolver, in the kresd section, there is an option dynamic_domains

In my device, which is only recently installed with factory defaults, the value of dynamic_domains is 0 - why?

This appears to be a regression of something that works by default in a normal OpenWRT clean install. Should that value be 1 by default?

It is also discussed (in the context of Turris Omnia) in the OpenWRT forum thread here

Changing dynamic_domains to 1 and running /etc/init.d/resolver restart fixed the issue for me.
