Nameservers are designated PER domain.  You tell the registrar for a 
particular domain that your authoritative nameservers are at whatever fully 
qualified domain name and IP address.


Prior to doing this with your registrar you should have the domain zone 
file properly setup on those nameservers.


Hope this helps.

Yes and no.

Glue records make it possible to find the the NS in the first place; 
you're avoiding a broken chain rather than any risk of loops.

zone for mydomain.example.com

IN  NS  ns.mydomain.example.com.
ns  IN  A   123.123.123.123



If you have the above, you've properly delegated the 
mydomain.example.com zone to ns.mydomain.example.com, but you'll never 
reach anything in that zone, as the only A record for the server is in 
the zone you're trying to find the server for, and you have no idea 
where that server is...


So you have to put a

ns.mydomain.example.com.IN  A   123.123.123.123

record in the example.com zone so that recursive lookups can find that 
one critical address and access the mydomain zone.  That's the glue record.

I found a page in NameScout's Help section that said that if I just

care of registering it automatically.  That seems to have worked, but it 
was not at all obvious that that's what I needed to do.


They also don't have any kind of automated interface for changing the 
name server info - one has to email tech support to do that.


I could see it causing a lot of trouble, if confused users enter 
incorrect info, and NameScout interprets that as a request to establish 
NS and GLUE records for a new name server!


Clearly, I myself have a lot of studying to do.

The Wikipedia article on the Domain Name System is very helpful, for 
anyone else wanting info on this topic.

Hello Mike,

 Just to point it out what i understand from your post is that you want the
NSs to
authoritative for your domain (example.com). So when someone queries for
xyz.example.com
your servers (a.ns.example OR b.ns.example.com) answer that query.

 Lets suppose the following example:
You have 2 server that you want to enable BIND (or whatever DNS application)
so they
are authoritative for example.com.
Server A - 1.2.3.4 - ns.A.example.com
Server B - 5.6.7.8 - ns.B.example.com

 First when you register a domain you must point a NS for that domain. So
when you register
example.com you will assign ns.A.example.com (and B) as NSs for that
particular domain.
Now if the NS for one domain has the name of the domain in it (sort of
speak, excuse my
non-tech language) as ns.A.*example.com* does you need a so called GLUE
record for
those NSs. There you point out the IP add of the NS in question.

Hope I understood right what you want and that my post helps you.

a great day,
v

bind 9 caching only name server best practice.

[Troy Beisigl]

Hi,

I'm looking for some information on what the best way to run a bind 9  
caching name server on FreeBSD 6.3 +. Basically, configurations and  
kernel tweaks on the FreeBSD side of things for memory and performance  
is what I am looking for. The actual Bind compile and configuration I  
understand. Does anyone have any insight on this they would like to  
share?


Thanks,

What makes you think it needs any more memory?  A caching nameserver isn't
a terribly memory-intensive unit.  In the past, I've run quite peppy
systems on a few hundred megs of RAM.

I expect the 207M is all the system actually needs.  Even if you figure
1K per entry, that's still 200,000 names it has cached.

/usr/ports/dns/bind9/

Read the Handbook for information on how to set things up.
Additionally, I'd suggest checking out Greg Leahy's FreeBSD book, now
available in downloadable PDF format from
http://www.lemis.com/grog/Documentation/CFBSD/.  Even better, buy it.

If you don't have a registered domain name, note that the "example.org"
domain is reserved for such uses; but any "fantasy" name should work,
providing the name you choose doesn't conflict with a real (registered)
domain.  

You'll also most likely want to add a DHCP server.

cd /usr/ports && make search name=dhcp

The rest is left as an exercise for the reader.

There are DNS ports, but the BIND name server is native to the 
system. You just need to config and enable it.


http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-dns.html

If you don't want BIND, DNS ports would be in ports/net.

dhclient doesn't know that you want to use a local cache, so it does
what it does - gets resolver addresses from your ISP.

Put this in your /etc/dhclient.conf:

interface "hme0" {<---  Change interface name accordingly...
supersede domain-name-servers 127.0.0.1;
}


And try again.  I believe, but haven't tested it, that you can use
prepend instead of supersede is you wish to keep your ISP's resolvers in
case your cache fails - but don't quote me on that!  ;-)

As for search order, use prepend:

interface "hme0" {
prepend domain-name "your.domain.here";
}

Configuring For Cache Name Server

[Gerard Seibert]

If I understand this correctly, if I want to enable a cache name server,
all I have to do is the following:

In /etc/rc.conf enter:
named_enable="YES"
named_flags="-u bind" 

Run this command: 
# cd /etc/namedb
# sh make-localhost

I enter the address: 127.0.0.1 in the /etc/resolv.conf file ahead of any
other entries.

I do not have to modify the /etc/namedb/named.conf in any way.

I can then either reboot or start the program manually.

Have I gotten that all correct?

OK, then why is it that the nameserver 127.0.0.1 gets removed on every
reboot of the system and the nameservers of my ISP are inserted.
Actually, I never removed them, I just placed the new one ahead of them.
There is also a search entry in the file. If I remove it, it also gets
rewritten upon boot-up. Maybe I should mention that I am employing DHCP
presently to obtain a lease from my ISP. Is there something I need to
alter in order to get this to work. If I cannot be done, it is no great
lose however. I can live with the system the way it is.

Waaauw, that sounds rather dangerous to me. I have a caching nameserver
running on an old Pentium-I with 32 Mb of ram (48 Mb swap). I am still
using it in a testing enviroment, moderately using the named's cache.
So far total memory usage by the OS is very low (swap is hardly used).
I wonder if named would eat up all the ram in a production enviroment.
Can't imagine that, actually. Nowhere I have seen warnings against
such disaster. But then there is this option for the named configuration
file, that limits the cache memory usage.
Well, some colleagues have some Machines with 512MB RAM running, also
bind 9, but with no given limit on size. They serve as resolvers to
several thousands of dedicated servers (customers servers) and use more
than 200MB RAM without being limited.
The example on Solaris is in a scenarion where a dedicated host has to
chew more than 30 GB http logs a day, does reverse lookups and then does
some statistics on them, so the named has to look up pretty much domain
names...
This special host has more than 10 CPU in it, so you can imagine the
power needed...
On other hosts, where I also run named as caching resolver, I have about
3-4 MB memory footprint for normal use...
How do you actually figure out how much memory is consumed by named?
I still have no idea how to do that, so I have no idea how much
my poor old Pentium-I is suffering from the named cache
Knowing how to do that, would help me already a little further.

Well, some colleagues have some Machines with 512MB RAM running, also
bind 9, but with no given limit on size. They serve as resolvers to
several thousands of dedicated servers (customers servers) and use more
than 200MB RAM without being limited.

The example on Solaris is in a scenarion where a dedicated host has to
chew more than 30 GB http logs a day, does reverse lookups and then does
some statistics on them, so the named has to look up pretty much domain
names...

This special host has more than 10 CPU in it, so you can imagine the
power needed...

On other hosts, where I also run named as caching resolver, I have about
3-4 MB memory footprint for normal use...

Can't imagine that, actually. Nowhere I have seen warnings against

Elsewhere, I have read that named uses 1 Mb maximum by default. But
I read that in an out-dated document. I assume meanwhile things have
changed/improved.

I also don't know what the exact default is, IIRC named takes all
memory it gets.

Looks like "user5.dhcp.company.com" is trying to submit a DNS update

You have your dhcpd configured to use 'dynamic dns' function.

When the laptop gets an address via dhcp, the dhcpd sends a message to dns
to update the dns name to the new IP address.
Some windows clients can do this also if the option is configured in the
Windows DNS settings.  Here I think it is your server as the log line comes
from "dhcpd".

In this case, the name "TM25.dhcp.company.com" already exists so dhcpd reports
this.
This may be due to a static entry in DNS zone files or because the laptop already
had an entry configured earlier.

You can check by doing a 'dig TM25.dhcp.company.com' and see what results you 
get from your DNS - you should see the name resolve to the IP address of the
laptop.

Regards,

Tony

Your first post included 'ipfw show' output.  Did you figure
out what was going on there?  Make sure that port 53 is
available, perhaps on both TCP and UDP.
As you see, I am no expert here.  I did "dig(1)" some of
the information in your last post, and based on that and
the content of your error messages, think that you need
some A records, for starters...

Thank you. :) Your idea to bind both nameservers on their own IP, with
rbldnsd on the alias, worked brilliantly well. Instead of configuring a
slave server, though, I went with forwarding, like so:

zone "dynablock.my-domain.info" IN {
 type forward;
 forward only;
 forwarders {
  127.0.0.4;
 };
}

And now everything works beautifully. :)

- Mark

P.S. Getting rbldnsd to work was worth the trouble. I have the entire
dynablock, blackholes, and proxies zones, from the soon to expire easynet.nl
RBLs, all loaded in under 22 MB! of memory (and rbldnsd keeps everything in
memory too, in case you wondered). The same cost BIND over 220 MB memory!

I don't think that's really going to work. You can configure a slave
server to do domain transfers on alternate ports, but that's about it.
Everything else expects DNS servers to answer on port 53. You'ld be
better off adding an alias address to the server and making each
server bind each to it's own address.  Don't know about rbldnsd(8),
but for bind9 you can put entries like this within the options{}
section of named.conf:

listen-on {
127.0.0.1;
12.34.56.78;
};
query-sourceaddress 12.34.56.78 port 53;
transfer-source 12.34.56.78 port 53;
notify-source   12.34.56.78 port 53;

(Nb. you can change the port number that bind uses in the 'listen-on'
statement but as I said above, there's not a great deal of use in
doing that)

See file:///usr/local/share/doc/bind9/arm/Bv9ARM.html for details.

Cheers,

Matthew

name server on alternate port

[Mark]

Hello,

If I want to install a second name server, on a different listening port,
how can I get the resolver libraries to consult the other port too? I want
to add rbldsnd, next to bind, for a large zone.

Thanks,

Problem with name server?

[Michael A. Alderete]

I just re-made my world to 4.9-PRERELEASE, using the instructions from the
Handbook, and everything appears to be working fine.

I do have one oddity, a number of messages that make it sound like named
cannot find the root name servers, e.g.:

Sep 18 15:09:25 ballista named[73]: sysquery: no addrs found for root NS
(A.ROOT-SERVERS.NET)

When I say "a number" of these, I mean on the order of 82471 entries, for
(all?) the root servers, A through M.

I don't believe I've ever had this problem before. My
/etc/namedb/named.root file has never been touched, appears to be
uncorrupted, and has the following version string:

$FreeBSD: src/etc/namedb/named.root,v 1.9.2.1 2002/11/06 09:24:12 dougb Exp $

Googling for the error message seems to indicate that it's not necessarily
a big issue, but given the number of log entries, I'd really like to
eliminate the problem. DNS resolution appears to be working fine, I just
want to keep my logs to a manageable size.

Thanks!

Michael
