[gentoo-user] How to set domainname

[gentoo-user] How to set domainname

[Anthony E. Caudel]

As of baselayout-1.12.4, the domainname init script is no longer used
and the Gentoo Handbook no longer tells how to set the domainname.
domainname now returns "(none)"

/etc/conf.d/net.example talks about setting up dns_domain but if this is
used, it overwrites /etc/resolv.conf.

So how is the domainname now set?

Well, perhaps.  It is in my /etc/hosts.  But domainname still returns (none)

By default, the 'domainname' command returns your NIS/YP domainname, 
which not many of us have.  Try 'dnsdomainname' instead - it may have 
the result you're looking for.

delta ~ # domainname
(none)
delta ~ # dnsdomainname

You should stop using /etc/hostname and use /etc/conf.d/hostname

I don't use /etc/hostname and I DO use /etc/conf.d/hostname.  What has
this to do with the domainname?  Are they both set there?

I thought domainname was set in /etc/hosts.  I put the whole kaboodle in 
it and it seems to work OK.

Here is my /etc/conf.d/hostname:
# Set to the hostname of this machine
HOSTNAME="uilleann.fancypiper.info"

And my /etc/hosts:
# /etc/hosts:  This file describes a number of hostname-to-address
#              mappings for the TCP/IP subsystem.  It is mostly
#              used at boot time, when no name servers are running.
#              On small systems, this file can be used instead of a
#              "named" name server.  Just add the names, addresses
#              and any aliases to this file...

There is no /etc/hosts on my system we are using /etc/conf.d/hostname but the
domain name is still not set.

See net.example.

# Setting name/domain server causes /etc/resolv.conf to be overwritten
# Note that if DHCP is used, and you want this to take precedence then
# set dhcp_ESSID="nodns"
#dns_servers_ESSID=( "192.168.0.1" "192.168.0.2" )
#dns_domain_ESSID="some.domain"
[...]
#nis_domain_eth0="domain"


The domainname is set with dns_domain or nis_domain.

No, it's not. NIS doesn't use /etc/hosts for these things.

That's not a hostname. A hostname has no dots (.).

This file is obsolete. So, it's not "as always".

Yes.

What is NIS?

So I should just have uilleann, tinwhistle and bones for the hostnames 
of my boxen, correct?

What exactly does /etc/hosts do, then?

Here is another guess:
How about /etc/conf.d/domainname?

Yep, should be configured as well. But as you can see there, it doesn't
set the domainname of the system:

# DNSDOMAIN merely sets the domain entry in /etc/resolv.conf, see
# the resolv.conf(5) manpage for more info.

Bullshit. It's not. But it's not for setting the domainname of a host.

Not "or", but "and". Depending on what domainname is to be set - NIS
or DNS.

So, where is it set then?  The /etc/conf.d/domainname is in my system. 
Why isn't it removed if it is obsolete?

But setting my domainname this way overwrites my /etc/resolv.conf and I
lose my nameserver data.
(This is noted in /etc/conf.d/net.example)

I saw that there was a /bin/domainname and /bin/dnsdomainname that both 
   are linked to /bin/hostname. I just used the command:

# domainname uilleann

and now the command:

# domainname

returns

uilleann

My /etc/resolv.conf remained unchanged.

Perhaps this is current usage?

Yep.

That's not a domainname, as there are no dots (.). Granted, a domain doesn't
have to have dots, but it's very unusual to have a TLD.

Also, I understood you so, that your hostname is uilleann.

Yep.

Of course. Why should resolv.conf be changed?

No.

In /etc/conf.d/net, as I already wrote.

First of, it wouldn't be removed, as the config protection
protects this file. But more importantly, it isn't removed,
as it is not obsolete.

Nope. resolv.conf doesn't have any influence on the hostname or
domainname. It controls, how names/ips are resolved.

If it would be as you say, what would be my domainname?

alexander@knospe:~/tmp/sources/samba/samba-3.0.22/source/utils$ cat /etc/resolv.conf
search bei.digitalprojects.com

The "domain" setting doesn't do what you say.

[...]
        domain Local domain name.
               Most  queries  for  names  within this domain can use short names relative to the

See? It's for "queries for names".

and from where does my machine get its domain name? It is only contained in

Re: [gentoo-user] How to set domainname

> So how is the domainname now set?

This was discussed here before; I think the solution was
to put something somewhere in a specific order. I have this working
properly and these're my files:

# cat /etc/conf.d/domainname
OVERRIDE=1
DNSDOMAIN="gvid.cz"
NISDOMAIN=""
# cat /etc/resolv.conf
nameserver 127.0.0.1
nameserver 10.0.0.3
search gvid.cz
domain gvid.cz
# cat /etc/hosts
127.0.0.1       univac.gvid.cz univac localhost
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
# cat /etc/conf.d/net
config_eth0=( "10.0.0.38 netmask 255.255.255.0" )
routes_eth0=( "default gw 10.0.0.2" )
dns_servers="127.0.0.1 10.0.0.3"
dns_domain="gvid.cz"
dns_search="gvid.cz"

Now try preserving the same order of lines and the same order of keywords on
each line. I think the one itching spot was to put the various names
on the first line of /etc/hosts in the prescribed order.

I beg your pardon, this was a different issue - "(none)" appearing
in the domainname's place somewhere else (possibly in the auto-generated
/etc/issue).

Good question. But as I've shown, it's not necessary to set it
in /etc/resolv.conf.

I am thouroughly confused now.  I previously had 
uilleann.fancypiper.info and that wasnt' a domainname because it had 
dots.  Now I have been told the opposite.  Both were written by you, so 
you have me in a fog of confusion.  Should I believe you since you have

That's not a hostname. A hostname has no dots (.).

I have no idea, but there is the /etc/conf.d/net.example which talks 
about setting up dns_domain but if this is used, it overwrites 
/etc/resolv.conf.  Someone was wondering how to set the domain name 
without changing resolv.conf, so I pointed that out.

Strange.  Why is the script there?  Why does it set the domain name.  It 
doesn't break my system, but I don't have my other boxen built and the 
OSs installed yet.  I can't test networking until I get those made.

* "domain" is the namespace where all your non-cacnonical 
  hostnames sit in, so necessary for constructing the canonical
  names (FQDNs).
  
  For example, if your box's name is "furunkel" and your domainname
  is "my-back.net", then your FQDN becomes "furunkel.my-back.net".
  
* "search" is the list of the namespaces where non-canonical names 
  are searched in on lookup.
  
  For example, you've got "foo.org" and "blubb.de" in your search list
  and you're doing a lookup for "mybox", it will try the FQDNs
  "mybox.foo.org" and "mybox.blubb.de".
  
I didn't ever try what happens when domain also added to search
list (maybe nothing, since its searched anyway), but it does not
make any sense.

The kernel knows it. Of course, it has to be set on each boot.
I actually have no idea, how gentoo sets it, but most obviously
it will be done by an "dnsdomainname" and "hostname" call.
Try a look at the boot scripts.

Pardon my thick skull. Alexander Skwar, I appoligise for my last post.

Darn this morphine I have to take for my pain.

I am confusing hostname and domain name.

I still don't understand why the script isn't supposed to be used to set 
hostnane/domainname though.

Yep. And all that's set in resolv.conf can be set in /etc/conf.d/net,
so I don't see the problem in having resolv.conf being overwritten.

What script?

Because the domainname is set with the domainname command. Gentoo
"automatically" calls domainname, when properly configured.

Because your domain name may change while your hostname stays the same,
or vice versa. Think of a laptop connected at various locations. Locking
the two together in one config file works against this.

What script? /bin/domainname is not a script, but a binary. And it's
this binary, which sets the domainname. But as most users don't want
to run domainname manually all the time, there are ways to make
Gentoo call domainname. One of this ways is setting up /etc/conf.d/net.

Yes, of course. In general, no unix command modifies configuration files.

That's not how I see the file. For me, the file is there to do stuff,

Gentoo is the only distribution I have seen use that particular file, so 
I consider it one of the "proper" ways to do things I can't figure out 
otherwise.

There is usually more than one way to "skin a cat" in Linux.

You should use /etc/conf.d/net to set the domainname.

True. Some are "with the spirit", some are not so much with the spirit
of the distribution.

So why does /etc/conf.d.net.example state

I think you'll find that only refers to that section of conf.d/net, the
part where system-wide global settings are set, as opposed to further
down the page where per-interface settings are configured. It could do
with a re-wording though.

So? It was a question and interestingly, you didn't answer this

Sorry, but I disagree with this interpretation.  The way I read it, it 
says that in the rare case that one should wish to change things such as 
domain, DNS, etc, one should use /etc/conf.d/net, but that a wireless 
user is more likely to need/want such configurability than a typical 
desktop user is.

Re: [gentoo-user] How to set domainname

[Jarry]

Hi,
I've been following this thread for the whole day, but despite
of reading many mails (unbelievable, how much mail-traffic can
such a simple question generate!), I'm still missing simple
yet exact answer (but maybe I have lost some emails).
So could someone please summarise it?

Supposing someone is using the last stable baselayout
(right now it is 1.12.4-r6 for x86 & amd64):

How and where to set up hostname?

How and where to set up domainname?

Thanks,
Jarry

Ok, I finally got it through my thick head. Ryan Tandy had pointed out
that "domainname" is not the proper way to display the FQDN; - it
displays the NIS/YP domainname which I don't have.  But his comment went
over my head until now.  "dnsdomainname" is the command I should have
been using and it does report the correct domain.

Also, I confirmed that my domainname (dnsdomainname) is being set in
/etc/hosts, as some others have pointed out.

So, thanks to everyone for their patience with me, especially Alexander
Skwar.

How about /etc/hosts ?

Context is everything. ;)  The post I was replying to was attempting to 
suggest otherwise.

In any case, how do I go about setting my domain name in /etc/conf.d/net 
if I still want to get my DNS server from DHCP (and I can't be sure it 
won't change without warning)?

Hm? Why should there be a problem? Just don't add a "dns_servers"
line to /etc/conf.d/net

It's working fine right now with the domain name being set in /etc/hosts 
- I'm just wondering if it's *possible* to do it the "proper" way 
without setting dns_servers_eth0.

You know, you can play your sniping game yourself. It's boring.
IOW: Read line 638 and 639.

I apologize if I appear to be trolling.  That's not my intention at all; I'm
more likely just not getting something (happens fairly often).  If that's the
case, maybe you can help resolve (haha, punny) it.

According to you:
 - hostname should be set in /etc/hosts
 - domain name should be set in /etc/conf.d/net (i.e., NOT in /etc/hosts)

According to /etc/conf.d/net.example:
 - DNS settings can be specified either per-interface, or globally (lines 638
and 639)
 - for any DNS settings (fex dns_domain) to be specified, the dns_servers
setting *must* be specified as well (line 637) (is this the point I'm
misinterpreting?)

delta ~ # cat /etc/hosts
127.0.0.1     delta    localhost
delta ~ # cat /etc/conf.d/net
config_eth0=("dhcp")
dns_domain_eth0="mydomain.com"
delta ~ # /etc/init.d/net.eth0 restart > /dev/null
delta ~ # dnsdomainname
dnsdomainname: Unknown host

What have I misunderstood?
