Re: Error: already exists previous definition

Hi
No, there's no duplicated directives in the zone file. For example,
here's the zone for another domain with the same error and here are the
only directives:
$ORIGIN   x.com.
$TTL   3600

Are there any duplicate include directives?

That looks very suspiciously like a file which has been included twice.
Check again. And again. :)

Are you quite sure? What are the modification times of named.conf and
*all files* it includes? [ls -l]

What does `named-checkconf' report?

Oh, and while you're at it, you should upgrade BIND -- the version you
are using is pretty old.

Well, this seems to have done the trick.  Changing it from yes to auto
has eliminated most (almost all in fact) of the validation
warnings/errors I was getting in my logs.

A.  So "yes" just enables validation but doesn't use any compiled in
root key?  If so, this is an annoying (all due respect) and small but
important distinction.

I'm not sure about anyone else, but a yes/no/auto selector to me means
either an explicit yes or explicit no with auto meaning some kind of "do
what you think is right" in terms of making it yes or no.  I don't
typically think of it as no or yes plus some additional functionality.

Anyway, you have my since appreciation for persevering with me in my
efforts to figure this out.

Slave DNS

2012-07-21 Thread With No Name
Hello *,

I have only one fixed IP from my ISP and run my own (Master) name server.

A friend from me in another Network segment does the Slave.

I do the same for him.

Now I am puzzeling arround, whether it is possibel, to setup the slave DNS
to accept any domains (including newly created) from a master...

I find it realy annoying, if I have ask every time the owner of the Slave,
to add a new zone.

Any Hints?

Thanks

Assuming your version of BIND is new enough, look at `rndc addzone' with
which you can add and remove zones at run-time w/out having to edit
`named.conf'.

Which mean, my DNS partner need his own rndc key which let him add/remove
zones as slave?

How can I do this?

I mean, I have to give him some permissions...

IIRC that will add the zone to the master, the question, as I heard it, 
was to add it to the slave server, to avoid disturbing the owner of 
the slave to manually editing the slave config.



I don't recall any possibility to do this, a new zone on the master may 
have it's own set of slaves, unlike any previous, so there is no way to 
automagically stuff a new zone into "some" slaves.

You are the master. He is the slave. You have an rndc key for his slave
server, so that you can add a slave zone on his server. [Substitute
he/his by she/hers if required.]

And vice versa. :)

Grab a recent copy of the ARM for the documentation and an example use,
and make sure you understand the security implications of opening up a
channel for rndc on each of the servers.

[SOLVED] Re: Slave DNS

2012-07-21 Thread With No Name
I have gotten a sugestion which should work very well:

1)  NS has apache SSL running
2)  Create a script which add/remove zones to/from a "slave zones list"
3)  run a cronjob which update the named_slave_zones.conf and reload named

This give me the possibility to create more then one "slave zones list"
for several friends and partners whitout being a single time bothered
with updates...

Thanks in Advance

With `rndc addzone' you specify whether you are adding a master or slave
zone, just as you would in named.conf, with all required options.

There is:

rndc addzone fff.aa in internal '{type slave; file "fff.aa";
masters { 192.168.1.10; };};'

Publish the list of zones which your friend should slave. That can be
published any number of ways

via http on a web site
via IRC
via usenet news groups
via dns zone transfer (dig slave1.slaves.somedomain.tld txt)

On the slave machine, periodically run a script to query the list of
slave zones and rebuild that part of named.conf as needed.
Then 'rndc reconfig'
