So I tried changing it from "Use Default Policy" to "Only Manually" and doing only that had the effect of changing NETCONFIG_DNS_POLICY in /etc/sysconfig/network/config from "auto" to "". Back in "Network Settings" the popup then said "Use Custom Policy" (before I restored it).

apart from the slightly unnusual search list, it looks good. "Laicolasse.valinor" is the laptop, right?
It is not reading those variables:

With that, you are expecting this? search valinor valinor nameserver 127.0.0.1 (I don't understand why you have two 'valinor', but that is irrelevanbt).

After adding NETCONFIG_DNS_STATIC_SEARCHLIST="valinor valinor" NETCONFIG_DNS_STATIC_SERVERS="127.0.0.1" I get a /etc/resolv.conf looking like this: search valinor local.hrz z.local.hrz i.local.hrz nameserver 127.0.0.1 nameserver 192.168.2.254 so the static config is merged/added to the dhcp config.

Not at all useless - "it works for me" means hope, it means it _can_ be made to work, given the right circumstances :-) Wrt /etc/sysconfig/network/config settings (DNS_*), I only touched the two settings I mentioned, the rest I left as they were installed: per@janeway:~> grep ^NET /etc/sysconfig/network/config NETCONFIG_MODULES_ORDER="dns-resolver dns-bind dns-dnsmasq nis ntp-runtime" NETCONFIG_VERBOSE="no" NETCONFIG_FORCE_REPLACE="no" NETCONFIG_DNS_POLICY="auto" NETCONFIG_DNS_FORWARDER="resolver" NETCONFIG_DNS_FORWARDER_FALLBACK="yes" NETCONFIG_DNS_STATIC_SEARCHLIST="valinor valinor" NETCONFIG_DNS_STATIC_SERVERS="127.0.0.1" NETCONFIG_DNS_RANKING="auto" NETCONFIG_DNS_RESOLVER_OPTIONS="" NETCONFIG_DNS_RESOLVER_SORTLIST="" NETCONFIG_NTP_POLICY="auto" NETCONFIG_NTP_STATIC_SERVERS="" NETCONFIG_NIS_POLICY="auto" NETCONFIG_NIS_SETDOMAINNAME="yes" NETCONFIG_NIS_STATIC_DOMAIN="" NETCONFIG_NIS_STATIC_SERVERS="" I'm using wicked on leap 15.5. -- Per Jessen, Zürich (0.6°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

Yes, and with wicked "auto" resolves to "STATIC *" which means - merge information from all interfaces *and* static entries.
Right - so both examples are working as designed, just differently. With NM, the dhcp config take precedence, with wicked, the dhcp and the static config are merged.

Well, then how do I make /etc/resolv.conf just have the config I decide? Using NM. Yes, I did look at netconfig(8), can't see anything relevant. I can't use YaST, the pertinent boxes are greyed out.

Are you kidding me? You have another system with NetworkManager that works the way you want. So just configure the new system identically.

Of course you will not find in netconfig(8) instructions how to do it "using NM". But you most certainly find a description of netconfig policies. So set NETCONFIG_DNS_POLICY="STATIC" and be happy.

No, you did not. This is one of rare cases when you did provide factual information from both systems so it was possible to compare them.

I absolutely did so. I copied the file over. And no, that file was not posted here, because I do not find the string "/etc/0_Legolas/sysconfig/network/config" in the emails. You could not see it and compare. So I post it now - previous laptop:

I said "configure the new system identically", not "configure netconfig on the new system identically". You wanted NM to provide a static DNS server list and on the old system NM is configured to provide a static DNS server list. I even told you how to do it earlier and it is exactly how NM is configured on the old system. So I really do not understand this thread at all.

No, I do not want NM to provide anything DNS wise. I'm forced to try to configure NM because netconfig doesn't do what I want. The file "/etc/resolv.conf" doesn't mention NM at all. In fact, NM should configure the servers in dnsmask instead and leave resolv.conf alone.
and on the old system NM is configured to provide a static DNS server list. I even told you how to do it earlier and it is exactly how NM is configured on the old system. So I really do not understand this thread at all.
This thread exists because simply I do not understand how to get the system to do what I need and I do not understand your explanations.

Right. I'm unsure why it doesn't have "valinor" alone. Another weird thing.
See Andrei's explanation - by default, it seems that NM ignores the sysconfig, so the above is all from dhcp.
But you are using wicked, I am using network manager, being a laptop.
I wonder if the choice wicked vs NM is based on whether a machine is installed with a window manager or not. I have two Raspis - one uses wicked and has no gui, the other uses NM and has a GUI.
And you get
search valinor local.hrz z.local.hrz i.local.hrz nameserver 127.0.0.1 nameserver 192.168.2.254
Where comes the "192.168.2.254" entry from?
From dhcp, along with the rest of the search domains.

(the problem is that this way it is it not using dnsmasq!)
The only way out I see is editing my own resolv file :-/
Done, it works. Will it survive a reboot? I guess not. :-(
Question:
What is the approved way to use Network Manager and DNSmasq on openSUSE?
This means:
a) resolv.conf ONLY contains:
search valinor nameserver 127.0.0.1
and never change.
b) the dnsmasq configuration must be adapted automatically to the external dns servers it gets via dhcp.
<https://en.opensuse.org/Special:Search?search=dnsmasq>
finds nothing relevant
Found something that works (it seems). /etc/sysconfig/network/config NETCONFIG_FORCE_REPLACE="no" NETCONFIG_DNS_POLICY="auto" NETCONFIG_DNS_FORWARDER="dnsmasq" NETCONFIG_DNS_FORWARDER_FALLBACK="yes" This produces in /etc/resolv.conf: search Laicolasse.valinor nameserver 127.0.0.1 nameserver 80.58.61.254 nameserver 80.58.61.250 which is acceptable. Notice that the older laptop doesn't use this. I don't know where that "search" is coming from, as the file contains NETCONFIG_DNS_STATIC_SEARCHLIST="valinor valinor" which is not taking. If I now say NETCONFIG_DNS_POLICY="static" Then I get: ### Call "netconfig update -f" to force adjusting of /etc/resolv.conf. nameserver 127.0.0.1 Laicolasse:~ # No search line. -- Cheers / Saludos, Carlos E.

The above is also what I'm using on a machine that has NM and dnsmasq.

Yup, that looks about right. That is your dhcp info plus the 127.0.0.1 (which NM has somehow figured out).
I don't know where that "search" is coming from,
dhcp.

No, 127.0.0.1 comes from NETCONFIG_DNS_FORWARDER_FALLBACK

No, 127.0.0.1 comes from NETCONFIG_DNS_FORWARDER_FALLBACK
Ah yes, I see it in the comments now. "an explicit localhost nameserver address". Just for fun, I tried to force my dnsmasq to only listen on 127.0.0.44, but I couldn't make it stop listening on 127.0.0.1.

I agree it makes sense to use «NETCONFIG_DNS_FORWARDER="dnsmasq"», but the old laptop doesn't have it. It has: Laicolasse:~ # grep NETCONFIG_DNS_FORWARDER /etc/0_Legolas/sysconfig/network/config NETCONFIG_DNS_FORWARDER="resolver" NETCONFIG_DNS_FORWARDER_FALLBACK="yes"

Yup, that looks about right. That is your dhcp info plus the 127.0.0.1 (which NM has somehow figured out).
Rather the 127.0.0.1 plus the dhcp info. The order is crucial.
I don't know where that "search" is coming from,
dhcp.
No. This is the dhcp dns config in my router: https://paste.opensuse.org/pastes/8ed26ccac8bb There is no entry to setup the search.

I think it would be more useful if you showed us the dhcp lease information instead. The config is specific to your router, we can't help with that. Try looking for the most recent lease: ls -lrt /var/lib/NetworkManager/*lease Here's is mine: https://paste.opensuse.org/pastes/37f3f013acdd

In /etc/sysconfig/network/config, do: NETCONFIG_DNS_POLICY="STATIC" NETCONFIG_DNS_FORWARDER="dnsmasq" NETCONFIG_DNS_FORWARDER_FALLBACK="yes" NETCONFIG_DNS_STATIC_SEARCHLIST="your_domain" NETCONFIG_DNS_STATIC_SERVERS="127.0.0.1" Then run "/run/netconfig/resolv.conf". This should result in an /etc/resolv.conf like this: Laicolasse:~ # cat /etc/resolv.conf | egrep -v "^[[:space:]]*$|^#" search your_domain nameserver 127.0.0.1 Laicolasse:~ # Notice that "NETCONFIG_DNS_FORWARDER_FALLBACK" doesn't work, so we do something else. Edit /etc/dnsmasq.conf: resolv-file=/run/NetworkManager/no-stub-resolv.conf #no-resolv Add dns servers of your choice, if/as wanted: # resolver4.opendns.com server=208.67.222.222 # resolver2.opendns.com server=208.67.222.220 # http://www.privacyfoundation.ch/ server=77.109.138.45 server=77.109.138.29 # https://digitalcourage.de/support/zensurfreier-dns-server server=85.214.20.141 #clooudfare server=1.1.1.1 server=1.0.0.1 # Google servers #server=8.8.8.8 #server=8.8.4.4 local=/your_domain/ Create or edit /etc/apparmor.d/local/usr.sbin.dnsmasq: # Site-specific additions and overrides for 'usr.sbin.dnsmasq' /run/NetworkManager/no-stub-resolv.conf r, Restart services: systemctl restart apparmor.service systemctl restart dnsmasq.service I think that's all :-) -- Cheers / Saludos, Carlos E.
