Software :: Zone Transfers For Load-balanced BIND Servers?

May 13, 2010

I am planning to implement hardware load-balanced DNS servers. There will be one master and three slaves in the server farm. I will have two virtual servers associated with the server farm that will be listed as external nameservers for our domain.

BIND uses the list of NS records to determine the servers that need zone transfers. The zone NS records will not be the addresses of any of the real servers. How do I tell the master to do zone transfers to the real slave servers?

Ubuntu Servers :: MySQL - Setup An Active / Active Load Balanced And High Available?

Mar 11, 2011

how to setup an Active/Active Load Balanced and High Available (If one of the nodes is down the system still runs) MySQL cluster. I have found quite a few howto's but I have some things unclear in my mind. I found a few solutions like this one: [URL] or this: [URK] Those are using two or four MySQL nodes, two Load Balancers to avoid a single point of failure but only one MySQL cluster management server. What happens if the MySQL cluster management fails?

I have also found a "MySQL Master-Master Circular Replication" technique but from what I read, with this option there is a chance that conflicts will arise if node A and node B both insert an auto-incrementing key on the same table.

Ubuntu Servers :: Samba Configuration - File Transfers Between The Machines Are Extremely Slow

Nov 1, 2010

1. When I'm not logged into the server, only the shares are visible on my Windows computer. Clicking on the share folder displays an error message. As soon as I log in at the server, the files within the shares become accessible on the Windows box.

2. File transfers between the machines are extremely slow. Watching the system monitor, there's a brief burst of network activity followed by 10-30 seconds of nothing...on a gigabit network, the effective transfer rate is ~120kbs. There's no other network activity going on that would account for this behavior.

Ubuntu Servers :: DNS Zone Delegation ?

Apr 28, 2011

I have an existing bind setup, which serves a local DNS zone: merlin.local.

I would like to setup a subzone, below merlin.local, (preferably ad.merlin.local) to be used by an M$ AD domain, and thus M$ DNS servers. I would like to then be able to lookup addresses in both of the zones mentioned from any machine on my network.

I thought that this would be as simple as creating a zone delegation in bind, however when I have done this, and setup an M$ domain using ad.merlin.local as it's DNS name. Whilst this hasn't presented me with any errors, as such, I have been unable to come up with a setup which allows me to lookup addresses in both the merlin.local domain and the ad.merlin domain. To be perfectly honest, I'm not sure what configuration I need to perform to allow this to happen, I stupidly assumed it would just work!

Ubuntu Servers :: Bind9 Errors: Unknown Option 'zone'

Aug 11, 2010

I am trying to get bind 9 up and running on a new installation of server 10.04 and keep getting errors when starting the daemon -

* /etc/bind/named.conf.local:19: unknown option 'zone'
* /etc/bind/named.conf.local:20: unknown option 'zone'
* /etc/bind/named.conf.default-zones:3: unknown option 'zone'
* /etc/bind/named.conf.default-zones:11: unknown option 'zone'
* /etc/bind/named.conf.default-zones:16: unknown option 'zone'
* /etc/bind/named.conf.default-zones:21: unknown option 'zone'
* /etc/bind/named.conf.default-zones:26: unknown option 'zone'

The onlything I could find after scrubbing the internet is once ina while there's a missing bracket. But I have checked and triple checked my config files and the syntax and can't find anything wrong. I have another installation of bind9 running on Fedora and the same exact syntax works just fine.

Ubuntu Servers :: Bind9 Views - Reverse Lookup Zone Doesn't Work ?

Apr 1, 2011

I'm at a loss to why my reverse lookup zone doesn't work for me.I've got two views. One internal and one external. My domain is Public IP:

dig -x @

gives me:

;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 2917
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0

I've set it up so that the internal subnets gets the domains resolved to the internal IP-addresses. When querying from external addresses I will get public IP.My named.conf.local file:

acl internals {;[code]..........

I don't know whether the views has messed something up. It worked before I added the views.

Fedora :: Get BIND Running On One Of Our F10 Servers?

Aug 12, 2009

I'm trying to get BIND running on one of our Fedora 10 servers, since we've had some issues with the DNS from our service provider. This BIND server is not authoritative for any domain, it's merely for caching purposes. I used the sample DNS file at [URL].., and modified it slightly with our internal IP addresses.

I'm getting the following errors when I do service named start:

Error in named configuration:
zone localhost/IN: loading from master file master.localhost failed: file not found
_default/localhost/in: file not found
zone loading from master file localhost.rev failed: file not found
_default/ file not found

I also tried changing the line directory "/var/named"; To the /var/named/chroot/var/named directory with the same result.

Ubuntu Servers :: Bind Phpmyadmin To Localhost Only?

Mar 18, 2010

Have basic LAMP setup on 9.10 box. I want to have a publicly accessible website AND I want to have phpmyadmin available. The only thing is I would rather not have the phpmyadmin interface available on the internet. I usually open a ssh port forwarded tunnel when I need to use phpmyadmin on this server. I want to add a directive to make phpmyadmin bind only on localhost. I have found the phpmyadmin config file in /etc/apache2/conf.d

phpmyadmin.conf -> ../../phpmyadmin/apache.conf

I have tried adding some LISTEN directives, but apache does not like my directives-- I am obviously not doing it right. I have looked for a bit on the internet and can't find out how to disable external access to a configured site in Apache.

Ubuntu Servers :: Bind-server With SQL In The Repositories?

Jun 19, 2011

I need a bind-server (I mean DNS server) with a SQL backend. As far as I have seen, the only viable option I have is to recompile bind9 with support for either MySQL or PostGre.

Link to this: [URL]with an additional

apt-get install libpqxx3-dev

From some tutorials I have read, I see I need to recompile it to enable its SQL support.

But when I do it that way, I won't get any security updates, won't I?

So... Is there any bind server with SQL support in the repositories ? For that I don't have to worry about security updates...

Fedora Servers :: Installing A DNS Server On 13 Running Bind

I'm thinking about installing a DNS server on Fedora 13 running bind. I looked around for available bind packages and found only these:

Now the first one contains bind utils the second one is for running DNS in a chroot env and the last one is a bind with some DB backend.

Does this mean that fedora 13 doesn't support/.provide "standard" bind server (I mean the one to run without chroot/without db backend) ? Or am I missing anything in my repolist which is :

Fedora Servers :: Mysql Driver For Bind In RPM Format?

anyone come across a mysql driver for Bind that is already in RPM format? I know there is one that you can compile, but i was just curious if anyone knew of a MAINTAINED package that does that same thing?

==Edit== While i'm at it, does anyone know of a way to have bind call a STORED PROCEDURE, instead of directly querying a table? That'd be sweet. --Or, even having bind query a php file, or a webhost, would be good... I'm going to google that one now....

==Edit== Screw the mysql driver: [URL]

Ubuntu Servers :: Bind Slave Tries To Update From Gateway?

Jan 21, 2011

I have 2 nameservers setup, a master and a slave. when I first setup the slave, I restarted bind9 and all of the zone records propagated just fine. Today, I updated one of the records on the master (no problems), but when I restarted bind9 on the slave it gave me a FAILED message. I checked the log and it was trying to receive notify's from my gateway address (, and got "Failed to update from non-master". I did some research and found several people having a similar problem, but their slaves were trying to update from their own IP, not from the gateway IP. I tried their solution (allow-notify {; }) but all that did was allow the slave to restart bind without errors, it still doesn't update the records. It says "zone is up to date" but it's not.

IP's are:


All of my zone records have the masters statement set to I don't know how it even came up with the gateway address

Ubuntu Servers :: 10.10 - Bind 9 Not Accepting DNS Client Queries

I have the dhcp giving out the dns server NSLOOKUPS from the client show query refused. I know there has to be some setting or config that will allow clients to query but I am not able to locate it, and I am not totally knowledgeable of named.conf and been all through the webmin module and configuration settings.

Fedora Servers :: FC11 Cannot Start BIND After Upgrade From FC10
