[opensuse] Setting domain name in Yast
On both Tumbleweed and Leap 42.3, if I set the domain name in YaST2 (Network Settings -> Hostname -> Domain Name), it seems not to be kept. If I check after saving it, it is once again empty. And the hostname command does not report it. In my case, the domain name is ramboll.ramboll-group.global.network, which I think should be accepted. It is not my choice for the domain name. It is the company domain. Isn't this the way to set the domain name? -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The traditional way is to set the fully-qualified hostname for localhost in /etc/hosts. For example, on my 42.2 laptop, I have the following: # IP-Address Full-Qualified-Hostname Short-Hostname 127.0.0.1 wizard.3111skyline.com localhost wizard (note: Short-Hostname can specify any number of aliases for the fully qualified hostname) It is the same on each distro I use. SuSE used to use a 127.0.0.2 ip as well, but that seems to have gone away. The correct entry in /etc/hosts insures dnsdomainname picks up the correct domain, e.g. $ dnsdomainname 3111skyline.com -- David C.

Well, you still need the entry in /etc/hosts unless you have an A record in bind (or other dns) running on localhost providing resolution for localhost/hostname. There have been a number of changes in gethostbyname, (though I don't recall the details) where this exact issue of local resolution and gethostbyname, dnsdomainname were not being handled adequately. I do recall the solution being a proper entry in /etc/hosts to provide local hostname/domain resolution. I run bind too (not on my laptop, but locally) and you still need the /etc/hosts entry. You are not providing an IP for your hostname, you are just providing correct resolution between localhost and your fully-qualified hostname. It can have any IP required provided by your network device config or dhcp. You can try with just dns, but then on localhost, make sure dnshostname resolves correctly. -- David C.

I've not seen mentions so far in this thread of the setting in /etc/nsswitch.conf RTFM The Name Service Switch (NSS) configuration file, /etc/nsswitch.conf, is used by the GNU C Library to determine the sources from which to obtain name-service information in a range of categories, and in what order. ... hosts: Host names and numbers, used by gethostbyname(3) and related functions. My entry reads: hosts: files mdns_minimal [NOTFOUND=return] dns Which means that it consults /etc/hosts first. I am also using 'dnsmasq'. Actually that is a very smart program, it not only reads in /etc/hosts so I _could_ omit 'files" from my nsswitch.conf entry, but it also handles DHCP as well and makes sure that when a DHCP IP address is handed out there is a corresponding DNS entry for it :-) Nice, eh? See also http://blog.uguu.waw.pl/2015/05/21/mdns-netbsd-linux-osx/ Do note that in https://www.tinc-vpn.org/examples/zeroconf-ip-and-dns/ it says This will allow your computer to resolve mDNS hostnames which addresses in the form of "something.local". and later Note that you can use a different top level domain than .local, but in such case you need to use mdns entry instead of mdns_minimal. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, super-smart. I've run into dnsmasq setting up PXEboot and it is orders of magnitude more user friendly than bind. But after running bind for nearly two decades and utilizing the ddns updates from dhcpd (which became all the more important with the proliferation of everything under the sun my kids drag in wanting an IP address), I've just stuck with it. -- David C.

A typical dns zone will also have an entry for 'localhost'. Well, I've always had that.

Not if you've got more than a couple of devices on the network. Also, you probably don't want to use it on a notebook computer that you use elsewhere. For example, on IPv4, the local DNS provides RFC1918 addresses for devices on my network. But if I'm away from home the host name for my main computer returns my single public IPv4 address, which then gets forwarded to the computer. Also, on IPv6, as an experiment, I set up Unique Local Addresses, which is used within my LAN, though I could use the global addresses. So, at home, my DNS returns those ULA addresses, but away from home, the public DNS returns the global addresses. Unique Local Addresses are the IPv6 equivalent of the IPv4 RFC1918 addresses. https://en.wikipedia.org/wiki/Unique_local_address -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That was my point. Editing /etc/hosts is OK if you only have a couple of devices, but can be fun keeping the file updated for several devices on several devices. That's why I started using my own DNS years ago. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't pretend to understand how this all works but this can't be the whole story. 127.0.0.1 is localhost and that is on a different interface to your fully-qualified hostname.

Since the loopback interface is not network addressable, never mind internet addressable!, there's no point in having a FQDN alias.

The interface is irrelevant. The hosts file, DNS, etc., are used to map a host name, including localhost, to an IP address. It's then up to the routing function of the operating system, to determine the appropriate interface etc.. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

At least on the past there was a tick box in YaST that would create an entry with 127.0.0.2 to the fully qualified name. But this entry breaks postfix.

I have the same problem on a system that uses static configuration, not DHCP.
The traditional way is to set the fully-qualified hostname for localhost in /etc/hosts. For example, on my 42.2 laptop, I have the following:
# IP-Address Full-Qualified-Hostname Short-Hostname
127.0.0.1 wizard.3111skyline.com localhost wizard
(note: Short-Hostname can specify any number of aliases for the fully qualified hostname)
It is the same on each distro I use. SuSE used to use a 127.0.0.2 ip as well, but that seems to have gone away.
The correct entry in /etc/hosts insures dnsdomainname picks up the correct domain, e.g.
$ dnsdomainname 3111skyline.com
It works perfectly fine without too. I never touch /etc/hosts. My environment - local DNS, DHCP and ifup/wicked.

Yes, that's a different issue. FWIW, I've just assigned host and domain statically on a test system - james.ramboll.ramboll-group.global.network "hostname -f" now says "Name or service not known", because that name cannot be found in DNS (nor in /etc/hosts).

After I switched the order in /etc/hosts (fqdn first, then the short machine name) I got the domain from dnsdomainname.

Well, apparently you need both /etc/hosts and /etc/hostname correctly populated.
You just need the name to resolve, either with /etc/hosts or with DNS.
I never touch /etc/hosts, but I have a working DNS and all server names are know/resolvable.

I just rely on Network Manager and have my home DHCP server configured to assign specific IP addresses to MAC addresses. This way, host name lookup works fine at home.

I use NM on the laptop. My DHCP server, when used, resides on the ISP router and it does not setup the names (it can't); thus the host.domain solving does not work and postfix crashes or complains bitterly failing to post anything. On other cases the DHCP is not under my control, and of course, fails to set the correct name (or is disabled, depends). The other DHCP server resides in my Android phone (tethering) and it also fails to set up the names. Or I can be at home and then NM sets a fixed IP. But not the name.

Do you not have your own DNS server? In Canada, most people use a firewall/router to connect to their ISP. It hands out NAT addresses and many can also provide DNS.

The router only have a cache DNS that solves internet addresses. There is no connection between the router DHCP and the router DNS, so that it is impossible to ask it for the IP of a local machine. Maybe such a router that hosts a *proper* DNS and DHCP server exists, but none of mine have it. Furthermore, postfix has been told what is the name of the machine it runs in, and it has to be able to learn the IP of that name (local network) - and this doesn't happen from the router DNS server. It has to be handled, somehow, in the machine that it is running in, a laptop, on a different home network than on initial config. Think about that ;-) The only manner I know is writing the name and address line in /etc/hosts. The machine also runs dnsmasq, but the IP/names pairs are configured mainly in the /etc/hosts file as well. So that file has to be edited correctly. -- Cheers / Saludos, Carlos E. R.

I used to run dnsmasq and put the host names in it's hosts file, but not on the other computers. As I mentioned earlier, I'm currently running pfSense for my firewall/router and it has a choice of DNS forwarder, DNS resolver or pointing to another DNS server.

Sure, but two caveats: It has to be running full time It doesn't know about the DHCP assignments. And, when I connect via phone tethering there is no router.

The traditional way is to set the fully-qualified hostname for localhost in /etc/hosts. For example, on my 42.2 laptop, I have the following:

What are the permissions on those files on the one that appears broken? (Should be 644 or 640, I think). What is actually in those files, and if you manually edit them do the values then appear in YaST? If you change the values via YaST, does the time stamp on those files change?

That appears to be the case. I just put a dummy name in Yast and it saved it to /etc/hostname. So, it appears Yast can't read a file it just wrote to. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I think it probably uses the same method as hostname to get the names. And that seems to want the text in /etc/hosts to be a certain way. So I suspect the problem is in a library function both use. I cannot say that I recall that /etc/hosts was ever where anyone looked to determine what the fqdn is. Isn't that what /etc/hostname is for? I suspect a regression somewhere. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

So when you set the machine name and fqdn in YaST, YaST should set the required files as needed. It fails to do this completely. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Maybe you wrote /etc/hosts manually in the wrong order once, and then YaST failed to change it again. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

It is not really up to YaSt to make assumptions about your DNS setup. YaST will update /etc/hostname, hopefully correctly, but that is all that is required. -- Per Jessen, Zürich (21.7°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

If you change the values via YaST, does the time stamp on those files change?
Both are 644 and the write time for /etc/hostname was changed yesterday, when I tried to add the domain name in Yast. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I have one system running network manager and it gets the domain in both those files. The other, is static config with ifup etc. That one does not show the domain name in Yast.
Same here. It is a static address. In fact the network segment is specifically not allowing DHCP as it is a test of this sort of thing and so we do not want the company DHCP server getting in the way. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

/etc/hostname on my system includes the domain name. I had to add the domain to the Domain Search box, to get the local domain recognized. I don't think that should be necessary, as that setting is normally for additional domains.
My Domain Search and Domain name are the same. It keeps the Domain Search. But not the name. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
