Much faster than BIND could ever achieve. The Either define an appropriate SELinux ruleset, or set it to disabled or permissive, again depending upon the security requirements of the server. I get the error, "xfrd: zone received error code NOT IMPL from" Make sure you specify that the seconday NSD server wants to do a AXFR transfer from the

Zones that have changed (via AXFR or IXFR) are written, or if the zonefile has not been created yet then it is created. Make sure you do this in a secure directory as the key file will be created in the present working directory by default: # cd /root # dnssec-keygen -a HMAC-SHA1 -b NSD database compile and reload Anytime you make changes to the NSD forward or reverse zone files you must recompile the database for NSD (nsd.db) with "nsdc rebuild". Most of these will be the default values, but we will uncomment the associated lines to make their values explicit.

The TSIG-verified zone transfer has worked. You can learn more about reverse mappings by reading the "A Bit About Reverse Zones" section of the Bind authoritative-only guide. Next, we can uncomment the lines that specify the key and certificate files. If you need help understanding what an authoritative-only DNS server is used for, check out our guide on the differences between DNS server types.

Follow On GitHub Tweets by @tlenss home rss search June 03, 2014 NSD DNS Tutorial A Fast, Secure Authoritative Only DNS Server NSD is an authoritative only, memory efficient, highly secure It can be compiled without OpenSSL, but of course you'll lose the ability to perform any cryptographic functions. In general, with hosting like DigitalOcean, this is taken care of by the hosting provider. To start with, we should configure the basic properties of our DNS server in the server section.

First, change the name to something more descriptive. The following message: Feb 2 12:32:42 dolan nsd[1906]: Could not tcp connect to No route to host 1 Feb 2 12:32:42 dolan nsd[1906]: Could not tcp connect to No The service expects to run as a user called nsd, but the package does not actually create this user account. Our values for this section should look like this: remote-control: control-enable: yes control-interface: control-port: 8952 server-key-file: "/etc/nsd/nsd_server.key" server-cert-file: "/etc/nsd/nsd_server.pem" control-key-file: "/etc/nsd/nsd_control.key" control-cert-file: "/etc/nsd/nsd_control.pem" Next, we will configure the key section.

Testing the Files and Restarting the Service Now that we have our master server configured, we can go ahead and test our configuration file and implement our changes. In a DNS zone file, the "@" symbol must be changed into a dot. Lets take a look at some configuration examples. addzones Add zones read from stdin of nsd-control.

This is a very quick way to make sure your DNS setup is correct. I have committed a change in our repository (NSD3 branch and trunk) that prints a better error message. For zones with no content, NSD may have backed off from asking often because the masters did not respond, but this command will reset the backoff to its initial timeout, for If you have a large number of zonefiles, it is worth creating a directory tree under the zonefiles directory to aid in administration.

These slave servers are supposed to initiate a zone transfer request later (to this server or another master), this can be allowed via the 'provide-xfr:' acl list configuration. num.tcp6 number of connections over TCP ip6. You can always install NSD from source if you want. The log can also be reopened with kill -HUP (which also reloads all zonefiles).

The server, remote-control, and key sections are already completely configured. We will set the name and file for each zone individually, so we don't need to worry about that in the pattern. num.ednserr number of queries which failed EDNS parse. As an authoritative-only DNS server, NSD does not provide any caching, forwarding, or recursive functionality.

Zone transfers which are encrypted with the same "sec_key" are allowed from the primary on to this box on We can pretty much use the exact same values for this file since the same email and authoritative name server are responsible for both zones. 2013020201 10800 3600 604800 3600 If a zone has been added or removed from NSD, you need to run: # /usr/local/nsd/sbin/nsdc rebuild # /usr/local/nsd/sbin/nsdc restart 12 # /usr/local/nsd/sbin/nsdc rebuild# /usr/local/nsd/sbin/nsdc To do this, issue the following command: sudo nsd-control-setup This will ensure that all of the credential files needed to control the daemon are available to us.

The pattern section will look something like this when you are finished: pattern: name: "frommaster" allow-notify: demokey request-xfr: AXFR demokey For the zone sections, the only thing Again, this configuration is only needed if you are setting up a seconday NSD dns server. ## NSD authoritative only DNS ## nsd.conf .:. IN NS no TSIG key).

As long as both master and slave have the same key defined, and are using the same key for each zone transfer (i.e. If you see a message like this on the slave … Feb 2 12:34:16 dolan nsd[1944]: xfrd: zone received error code REFUSED from 1 Feb 2 12:34:16 dolan nsd[1944]: It is absolutely critical to set your "NS" name server hostname (ns1.home.lan to in this example) to the same ip address NSD is listening on. A few of the root nameservers use NSD, as well as the .se ccTLD.

STATISTIC COUNTERS The stats command shows a number of statistic counters. Typically, this process should complete in the next 24-48 hours. This value must be incremented every time that you make a change to the zone file. And when rebooted.

You should substitute your own domain to follow along. Create the Reverse Zone File Next, we will make a similar file for our reverse zone.
