How to set DNS servers for DHCP server?
location: ubuntuforums.com - date: October 18, 2011
I'm confused. I want all clients on the LAN to use OpenDNS as the DNS server.
Eth1 is the LAN side nic and a DHCP server.
I went to System/Admin/Network Tools/Devices/eth1/Configure/Auto eth1/Edit/IPv4 Settings and set the DNS Servers as "22.214.171.124,126.96.36.199"
As an aside, on that same page, what is the text box labeled "Search Domains"? What's the difference between DNS Servers and Search Domains?
But the main problem is the DNS servers I specified are not propagated to the clients. If I let the client automatically obtain DNS Servers, it does NOT get those two DNS servers (it doesn't even get one). In fact it gets 188.8.131.52 and I don't even know if that's a real DNS server.
I looked in /etc/network/interfaces and the only thing there is:
iface lo inet loopback
So where are the interface settings for eth0 and eth1?
Any help will be greatly appreciated.

How do I perform maintenance on a master DNS/DHCP (BIND9/ISCDHCP) Ubuntu server?
location: ubuntuforums.com - date: September 6, 2013
I'm running non-GUI Ubuntu Server 12.04.2 LTS (64-bit) on my 2 DNS/DHCP servers. Both servers are running BIND9 9.8.1-P1 and ISC-DHCP-SERVER 4.1.ESV-R4-0ubuntu5.6. Please note that for DNS I'm running them in a master/slave configuration, and for DHCP they are running a failover configuration. Ideally, I'd like to perform maintenance on the master/primary first, and once it's back up and running, I'd like to then take care of the secondary/slave. Maintenance will consist of installing various updates and performing a restart. I'm uncertain how to gracefully bring each machine down without losing/interrupting service. Any advice is greatly appreciated!

HOWTO dump/export the cache of a BIND DNS server
location: ubuntuforums.com - date: August 28, 2008
Last night I spent about an hour looking around google for how to dump and view the cache of a bind dns server. I just wanted to post this thread on how to do it so maybe next time people search they will able to find it easier
Bind 9 makes it fairly easy to dump and view the cache of a caching BIND DNS server. All you have to do is run under root:
rndc dumpdb -cache
This will create a file called named_dump.db in the /var/cache/bind/ directory. You can easily open this .db with your favorite text editor.
** If your instance of BIND is chrooted, for example to /var/lib/named/, then the cache dump file will be located in the /var/lib/named/var/cache/bind/ directory.
** The dumpdb feature of rndc has other options including a -all or -zone flag. Check 'rndc --help' for more information.
For more information you can check out this HOWTO i drafted.

Few days ago, I installed bind9 server on my fresh debian 7 machine. All packages are up2date, and repositiries are offical.
I have configured bind exactly as it is described here:

Anyways, as I have only production domain, and I can't move them to my new DNS server, and I want to check if all is working fine..
On the server all seems to be good, I replace all fields in resolv.conf to use this server so:
