There's another box just to the right of host name for domain name. However, it doesn't appear to save it. I use Domain Search as a work around. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

My understanding, going all the way back to when I was doing 3rd level OS/2 support at IBM was the domain name specified the first one searched. If additional search domains were needed, they were added to the domain search list (LAN domain search in OS/2). In openSUSE 15.0, the Domain Name box is still there but, as I mentioned, doesn't save it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Indeed only root can do this. Also echo or sysctl can be used to set the domainname. The DNS domainname can not set local but only provided by the (remote) name server providing the database of the DNS. For this /etc/resolv.conf is used to get the address of the remote name server. You can also run a local name server daemon (bind or dnsmasq) to provide such a DNS for the LAN, for this then the /etc/resolv.conf points to 127.0.0.1. To solve trouble at boot (local or of the host providing the name server) or lost LAN some common FQDN can be written into /etc/hosts. -- "Having a smoking section in a restaurant is like having a peeing section in a swimming pool." -- Edward Burr

Ah, you are saying that a call to domainname can set the domain name. man: «When called with one argument or with the --file option, the commands set the host name or the NIS/YP domain name. hostname uses the sethostname(2) function, while all of the three domainname, ypdomainname and nisdomainname use setdomainname(2). Note, that this is effective only until the next reboot. Edit /etc/hostname for permanent change.» So the file to edit is "/etc/hostname". Elesar:~ # domainname Elesar Elesar:~ # domainname Elesar Elesar:~ # hostname -f hostname: Name or service not known Elesar:~ # Well, no, that's not quite it. man «It is not possible to set the FQDN or the DNS domain name with the dnsdomainname command (see THE FQDN below).» Ah. «The FQDN (Fully Qualified Domain Name) of the system is the name that the resolver(3) returns for the host name, such as, ursula.example.com. It is usually the hostname followed by the DNS domain name (the part after the first dot). You can check the FQDN using hostname --fqdn or the domain name using dnsdomainname.» Well, no: Elesar:~ # hostname --fqdn hostname: Name or service not known Elesar:~ # As it is a dynamic IP, the DNS can not know about the machine. «The recommended method of setting the FQDN is to make the hostname be an alias for the fully qualified name using /etc/hosts, DNS, or NIS. For example, if the hostname was "ursula", one might have a line in /etc/hosts which reads 127.0.1.1 ursula.example.com ursula » Well, as I said, this method collides with postfix. When I did that, I got this once per minute: .... fatal: parameter inet_interfaces: no local interface found for 127.0.0.2 «Technically: The FQDN is the name getaddrinfo(3) returns for the host name returned by gethostname(2). The DNS domain name is the part after the first dot. Therefore it depends on the configuration of the resolver (usually in /etc/host.conf) how you can change it. Usually the hosts file is parsed before DNS or NIS, so it is most common to change the FQDN in /etc/hosts. If a machine has multiple network interfaces/addresses or is used in a mobile environment, then it may either have multiple FQDNs/domain names or none at all. Therefore avoid using hostname --fqdn, hostname --domain and dnsdomainname. hostname --ip-address is subject to the same limitations so it should be avoided as well.» Well, as the IP is set by DHCP, I need some script to write the correct current entry to /etc/hosts. Meanwhile, write it manually on each boot. But with that alone, "hostnane -f" fails.

Oh, I know very well how to combine "in Linux" dnsmasq with a proper dhcp server. But remember, in this case, I can not ensure control of the dhcp server. I may be a guest at somebody else's place, I may be using Android tethering... (actual situations in which my laptop gets into). So, knowing that the dhcp is in the router or the phone and that I may not have control of it, how do I make dnsmasq adjust to my current local IP, obtained dynamically, on a different machine? Just a theoretical question :-) If pressed, I can figure how to do it, via passwordless ssh sessions and scripts I'd have to develop. But maybe there already exists a command to do it that I'm not aware of. I already have my own scripts to do that with NM and dnsmasq running in the same machine. If I don't do that, postfix for sure fails in 15.0. I don't remember if dovecot failed, and leafnode also had problems. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.0 x86_64 (Minas Tirith))

Yes if "Assign hostname to loopback" is checked. It is quite possible that default for this checkbox changed at some point. I am fairly sure it was default in the past, but my 15.0 installation did not have this entry until I played in response to this thread. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not many people use postfix nowdays to send mail outside, instead of directly from Thunderbird or whatever. It is possible that some other setting is needed in postfix to trigger the problem, that having 127.0.0.2 name.domain name is not enough. Another question: how can YaST write that entry if it doesn't know the domain name? When posfix is configured using YaST, how is the domain name written to the configuration? etc. Just wondering. :-? -- Cheers / Saludos, Carlos E. R.

Does YaST write that entry, in 15.1 ? In 15.1, I can't find that option Andrei mentioned "Assign hostname to loopback", so it probably doesn't. On 15.0, when I ticked that box, I see 127.0.0.2 gaston.local.net gaston added to /etc/hosts.

Right.
Well, it does. Perhaps it needs some other setting that you don't use and I don't know which. Maybe the one that defines the interface or the name or domain to use. Or maybe you have to restart it. Maybe if it "knows" the machine name is gaston.local.net then it tries to locate the interface; hosts says it is 127.0.0.2, and then fails to bind to that address, it has no interface. Something like that.

I think you missed the point - postfix is started and runs, with no problems, in the default config. If people don't know about it, that's their problem :-)
I submit - in the default config it does not. When you then change the config, it's entirely up to you.
There is no black magic here, postfix does exactly as it is told. In the case of 'gaston', postfix never touches eth0, it only listens on loopback. Of course, if the config is changed to include listening on 'gaston.local.net' = 127.0.0.2, then postfix will fail. -- Per Jessen, Zürich (12.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yeah, I know it runs fine by default.
But all my LAN machines with openSUSE (except some test partitions) have a postfix that listens on the eth0 or wifi port and accept/send mails to other machines in the LAN. I have to change the default config for that - and typically, I use the YaST mail module for this change. Now that in 15.1 the 127.0.0.2 line is not created, I don't expect that problem.

"Domain Name" field in YaST has very little to do with FQDN.
It adds the domain name to resolv.conf. If the domain name is not in that file, then yo u must use the FQDN to access anything on the LAN. Here's some info from the resolv.conf man page: "domain Local domain name. Most queries for names within this domain can use short names relative to the local domain. If set to '.', the root domain is considered. If no domain entry is present, the domain is determined from the local hostname returned by gethostname(2); the domain part is taken to be everything after the first '.'. Finally, if the hostname does not contain a domain part, the root domain is assumed. search Search list for host-name lookup. The search list is normally determined from the local domain name; by default, it contains only the local domain name. This may be changed by listing the desired domain search path following the search keyword with spaces or tabs separating the names. Resolver queries having fewer than ndots dots (default is 1) in them will be attempted using each component of the search path in turn until a match is found. For environments with multiple subdomains please read options ndots:n below to avoid man-in-the-middle attacks and unnecessary traffic for the root-dns-servers. Note that this process may be slow and will generate a lot of network traffic if the servers for the listed domains are not local, and that queries will time out if no server is available for one of the domains." Notice what it says about the domain name and search domains. You need the local domain to be listed in there somewhere.

This field had very little to do with "hostname -f". "hostname -f" returns result of name resolution. So define your FQDN in /etc/hosts or on your DNS server. That happened when "Assign hostname to loopback" was checked - YaST added entry to /etc/hosts with FQDN (hostname.domain) so "hostname -f" worked. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

You yourself admitted earlier that you do not even know what entering "Domain Name" in YaST actually did.
So you claim that if you enter "Domain Name" in YaST and are on system with dynamic IP something will enter FQDN matching current IP in hosts file automatically for you. Is it correct? Otherwise how is it all relevant to your original question?

Right, that's the normal behaviour.

A machine will always only have one name, but may be reached by multiple other names. I don't think it would be right for our network config to assume the presence of a local DNS. Maybe the question ought to be "with no local DNS, why do you need a local domain name?"
It's a moot point now, but looking at some of my elderly machines, the domain name was written to /etc/HOSTNAME - I see e.g. "linux.suse" or "linux-0ya0.site" on some of them. -- Per Jessen, Zürich (9.4°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't think I follow? You added a line on resolv.conf with domain jknott.net ? Ah, I see: (man) domain Local domain name. Most queries for names within this domain can use short names relative to the local domain. If set to '.', the root domain is considered. If no domain entry is present, the domain is determined from the local hostname returned by gethostname(2); the domain part is taken to be everything after the first '.'. Finally, if the hostname does not contain a domain part, the root domain is assumed. It says that if not present, it is obtained from gethostname(2). How can that call know the fqdn from DNS using only the "name", not the domain name? For instance, the dns can know about several machines with the same name and different domains.

Long post showing what I tried, the process - at the bottom, the finding. Quick answer: the domain name is simply written in /etc/hosts, matching the machine name with an entry in that file. On 08/05/2019 19.33, James Knott wrote:

Then how do that machine knows which is the domain name? It must be defined somewhere, it is the LAN DNS server. In that machine, "hostname -f" is working. The answer so far in this thread is that the DNS tells. Ok, but how does my dnsmasq in 15.0 obtain that info from?

There isn't a requirement /etc/hostname even be present, but traditionally it has always held the hostname for early-boot when there are no servers running to provide it. It can contain the DNS domain portion of the hostname as well, but most of the systems I have simply have the hostname without the domain component. (I'd be more apt to include it on systems using a fixed address) One of these days I'll have to come out from under my digital rock and chase down exactly how it is handled now. It's been since the dnsdomainname / gethostbyname changes half a decade or so ago that I even looked. One thing that is rather strange is 15.0 has no domain component in /etc/hostname, but it is included in /etc/hosts, 42.3 is the exact opposite.

So instead of having to type 'history | grep "whatIwant"' each time, I add a simple function and alias to my .bashrc, so all I need to do is type 'hist whatIwant'. The function and alias are: showhist() { [ -z "$1" ] && { printf "usage: hist <search term>\n"; return 1; } history | grep "$1" } alias hist='showhist' I generally create a function that gives some usage information if I just type the name and forget to type the required arguments. Better yet, you would have it respond to '-h' or '--help' as well :) -- David C.

But it is a new system, I did not write what was on the /etc/hosts file myself.

Nowhere! The domain name belongs to an active network device. Only the domain name of a YP/NIS domain can be set. And this active network device is used to ask the domain name server for the FQDN of the system.

Next question: then what was the purpose of the domain entry box in Leap 15.0 and all previous versions since I remember?

e.g. boo#821599 and boo#1099464 AFAICR postfix as well as sendmail uses gethostbyaddr(3) to ask for the FQDN of local system for (one or more) of its network device(s). The resolution depends on /etc/host.conf, /etc/nsswitch.conf, and /etc/resolv.conf together with /etc/hosts in the default configuration. On static network configuration (e.g. with wicked) the FQDNs of the local system can be added for one or more of its network devices into /etc/hosts. On a mobile system (e.g. NetworkManager) I'd prefer not do this but let do the job the NetworkManager and its DHCP part.
