I don't understand.

mac & IP go together in dhcp and arp
hostname & IP go together in DNS & /etc/hosts

hostname & mac & ip go together nowhere

arp updates when the host comes on-line
dhcp & dns are separate from individual VMs, populating those services
is part of provisioning them.

Perhaps detail more what you are trying to accomplish?

ISC dhcpd can update bind when a host requests an IP.

As it is related to this thread, which server would people recommend when the 
DNS records are to be found in a database?
Reason I am asking:
I want to set up a lab environment with VMs coming and going.
These all need to have hostname/mac/ip stored and configured correctly.

Till now, I basically preconfigured Bind and DHCPd for a bunch of them.
I would prefer to be able to specify a hostname for this, but writing 
something that keeps changing the configuration and keeping it in-sync with a 
database is a bit overkill.

In your SMTP-server config, did you configure "Send custom hostname to server"?
Also, check the output of " hostname -f ".

auth or cache?

First of all, bind is a pain to use. Reason: it's actually a reference
implementation that as usual got forced into production use. It's slower
than it could be because it deals with every possible corner case per RFC.

As an auth server (few queries) it's OK
As a cache (many queries), there are better servers out there. I prefer
unbound.

I don't understand. DNS servers don't keep routes in memory - routers do
that. Perhaps you mean cached DNS records?

DNS is light on RAM, there are only so many records typical users will
look up. DNS caches not too long ago ran for years problem free with a
puny few hundred MB. It's not something to be worried about.

[gentoo-user] A direct keyboard layout switch for xfce4

[Gevisz]

I am asking this question here after discussing it
at vim_use mailing list (as an slight off topic to
the "vim and touch typing" thread) and after an extensive
google search earlier.

Below is some resumee from that discussion but for those
of you how do not want to read all that I just formulate
my question in short first: "Is there any plugin or
application working under xfce4 that allows switching
the keyboard layout directly, that is not by circling or
toggling it.

By a direct keyboard switch I mean the way to switch 
to a certain keyboard layout irrespectively of the its
initial state. For example, I need a (configurable)
hot key to switch to a Cyrillic keyboard layout if
I am currently in the English keyboard layout and
to do nothing if I am already in the Cyrillic keyboard
layout.

As far as I know it is impossible to do with the current
X config and/or xfce4 keyboard layout switch plugin.

So, my original post at vim_use mailing list was as follows:

And what if not?

I may try this solution but I still have to google how to send
a SIGNUP signal to X and, moreover, to find out how to send it
in a quick and convenient way. Otherwise this way will not be
a solution at all.

Moreover, even before trying it, I suspect that this way of
achieving a "direct hot key keyboard switch" will cause X to
re-read its configuration from a file on a disk that can take
a noticeable time, which is not desired.

The true solution to this should be to keep all the needed
keyboard layouts in memory and only change the pointer to
the corresponding memory locations by a corresponding hot key.

I believe that such a solution should be provided in the X configuration
and realized in the corresponding window manager plugin but, as far as I know,
it is not. That is why I wrote that it is impossible in Linux (unless you
can re-write X, of course :).

What I do currently:

Edit Bind zone-files and enter IP / Hostname combinations
Edit DHCP config file and enter MAC / IP / Hostname combinations
(And hope these actually match and not contain typos)

What I want to do:

In a database I have a table with the following fields:
MAC, IP, Hostname, domain
xx:xx:xx:xx:xx , 1.2.3.4 , vmobi1114node1 , vm1.lab.example.com

I want the DNS server to use the IP, Hostname and domain fields for the 
resolving.
I want the DHCP server to use all the fields for the DHCP assignments.

[gentoo-user] Wrong domain in e-mail failure messages

[Peter Humphrey]

Hello list,

I've just received a delivery failure message from my ISP, zen.co.uk, saying 
it couldn't deliver an e-mail I'd sent. There's only one thing wrong (apart 
from the reason for the failure, which is out of my control). It's shown in 
the second line of the failure notice:

Received: from [xx.xx.xx.xx] (helo=wstn.localnet)

I've bowdlerised the IP, and wstn is the name of this box, but where did it 
get localnet from? I've grepped /etc for it, and I've searched my home 
directory tree for it. Both searches turned up empty.

I use KMail, which is set up to send all outgoing mail directly to my ISP via 
SMTP; no other box is involved. And I hope my ADSL router isn't interfering.

My head's getting sore from being scratched. Has anyone a clue for me?

 auth or cache?

 First of all, bind is a pain to use. Reason: it's actually a reference
 implementation that as usual got forced into production use. It's slower
 than it could be because it deals with every possible corner case per
 RFC.

 As an auth server (few queries) it's OK
 As a cache (many queries), there are better servers out there. I prefer
 unbound.

OK, that makes sense. You'd think all decent DNS and DHCP servers out
there would support any old arb db backend (very useful, no?) but it
seems not. I've gotten used to independently vi'ing two files and
HUP/reload two daemons over the years :-)

Bind can use a mysql backend, so can most auth servers. The only dhcp
server easily available on gentoo seems to be dhcp from ISC which does
not support mysql. But both support ldap, maybe you can use that?
There's lots of ldap frontends so getting your info into it should be
easy enough.

You could also look into kea (https://www.isc.org/kea/), a better dhcp
server from ISC. The blurb says it supports SQL backends.

Same here. Works for the most part, but I'm not the only one using the system.
Which means I prefer to have it easier to use and not end up having to do all 
the work myself.

> Bind can use a mysql backend, so can most auth servers.

Need to check how difficult/easy it is to make it listen to PostgreSQL.
I'm not overly attached to Bind. Having a DNS server that's easier to configure 
and maintain would be appreciated.

That's one option, but that would mean maintaining 2 databases.
One with the config for the VMs and OpenLDAP.
