[opensuse] Domain name doesn't stick
I'm running 42.3. One thing I've noticed is that the domain name, as entered in the Domain Name box, in Yast Network Settings, doesn't last through a reboot. It also gets removed from /etc/resolv.conf. Any idea why this happens? How to fix it? tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Do you mean Hostname/DNS tab?
doesn't last through a reboot.
What exactly does it mean? Where you expect it, what files you check, what commands you use?
It also gets removed from /etc/resolv.conf.
When it appears in resolv.conf before it gets removed?
Any idea why this happens? How to fix it?

Yes.
It means that after a reboot, it's no longer in resolv.conf nor in Network Settings on the Hostname/DNS tab.
It also gets removed from /etc/resolv.conf.

Yes. Of course it's in resolv.conf. It's saved there when saved in Yast and disappears from both on reboot. The resolv.conf file shows a write date & time corresponding to the reboot. So, something is writing to resolv.conf, without the domain name.

I don't use DHCP on that computer. Static config only. Also, the IPv6 router advertisements are providing the domain name, but I can't resolve local hosts, unless I include the domain name.

What are other settings (nameservers, DNS policy)?
What "hostname" and "hostname -d" say? What /etc/hostname contains before and after reboot?
It also gets removed from /etc/resolv.conf.
That's likely side effect of something else, file is rebuilt every time network configuration changes. Most likely your hostname changes.

It currently shows the host name and I'll check again when I reboot. However, the problem is not about the host name. It's about the domain name disappearing. As I mentioned in another note, I use pfSense for my local DNS. It has the host name and domain name included for each entry. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It's been a while, and things have changed, but in the past, the fully qualified hostname should be the first entry for the static address in the hosts file, for example: 10.0.0.20 kosmos1.gentoo.co.nz kosmos1 So I wondered if this was the case here. If it isn't you might try manually setting it that way. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

As I mentioned, the problem is the domain name disappearing from /etc/resolv.conf. Resolv.conf normally contains a search line, that contains the domain name. That line is there after I save it, but is gone after reboot. Something is causing that file to be written without that search line. When that line is there, I can do a host lookup using only the host name. When it's not, I can't. This has nothing to do with /etc/hosts, as I am not using that file on this computer for name resolution. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Look for NETCONFIG_DNS_STATIC_SEARCHLIST= in /etc/sysconfig/network/config The values of this parameter will be put in /etc/resolv.conf in the searchlist with domain name(s) each time the network is started.

Hostname shows the hostname & hostname -d doesn't show anything. Host shows the full host name and domain, along with the IPv4 and IPv6 addresses, before reboot, but can't find the host after, unless I add the domain. I'm running pfSense as my firewall router, which included DNS resolver.
I am not changing anything. I have a static configuration on this computer. The only thing that happens automatically is IPv6 SLAAC address and the router advertisement, which contain the correct domain name. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I have a strong suspicion... systemd and many of the newer network managers take control of resolv.conf (some do away with it completely and use a similarly named file).

Sorry James, I understood that. I wasn't clear. When you set a fixed/static network configuration, you would normally expect that to mean: "systemd or you network managers -- keep your bloody mitts off my resolv.conf" (and other config files), but there is no guarantee of that. I don't know off the top of my head where you tell systemd (or the other network managers) to not touch your setup, but there is a way to do it. When I stumbled through the first few configs with systemd, I recall wondering how Yast would deal with this stuff, but I haven't had openSuSE on a box with a fixed IP since the switch to systemd. On Arch, for a fixed IP, (I'm still using IPv4), I just use a minimal netctl service file and put a soft-link in /use/systemd/system/multi-user.target.wants/. Thankfully, netctl is one of the few systemd networks management schemes that continues with a traditional resolv.conf and has been problem free for my basic setup. All I care that resolve.conf does is resolve DNS searches for my domain (which it does not lose) on localhost and then Bind9/named.conf specifies the forwarders I want to use. That setup continues to work as it has since the beginning of time (well at least the last 17 years) I don't see why you can't do an IPv6 setup the same way. Make sure your host and domain name resolutions are working as expected (e.g. $ hostname and $hostname -f) as there have been some changes in gethostbyname and getdomainname a couple of years ago that did make subtle changes to what entries get drawn from where (the specifics escape me now). But if your host/domain name setup survives boot, there is no reason a simple static setup should have problems finding them.

My first thought was it might be something sysd is doing -- but call that an *unsubstantiated* feeling. Then I thought about how to figure it out... You say /etc/defaultdomain's contents are changed. Try, as root, setting the immutable bit on the file: sudo chattr +i /etc/defaultdomain. Now when you reboot, **hopefully**, you will see an error message about how the file can't be written to (unless someone also toggles the immutable bit to write to it (which would be rather evil)).

That file is empty and shows a write date of May 17, so I don't think that's the problem. As I mentioned earlier, /etc/resolv.conf was changed to remove the search domain. However, I have found a work around. I found that if I put the domain name in the search domain box, rather than domain name, the search domain stays in resolv.conf and works as expected. There is clearly a bug here, but someone else reported it earlier.

--- If above is false, then apply the debugging measures to the one that *IS* changing. Whichever. I.e. if its another file, then make that one immutable so if anyone tries to write to it you can catch it.
As I mentioned earlier, /etc/resolv.conf was changed to remove the search domain.
Ahh, too many responses -- couldn't see where you mentioned what file changed. I'm sure you mentioned it, but started to be too many responses to go through again.
However, I have found a work around. I found that if I put the domain name in the search domain box,...
if the workaround works for you, *great*. I just "overfocused" on this:

I just figured tossing out an error when someone tried to change it might help track it down. :-) -l -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
