Configuring NSD

1. Log in using SSH/Putty/... to your AUTH2 machine:

    $ ssh sysadm@auth2.grpXX.dns.nsrc.org
	
	Firstly, note that your hostname is configured correctly
	on your machine.  Check that it is configured correctly by
	using the 'hostname' command - e.g. on auth210.10.grpXX.dns.nsrc.org, if you type:

	 # hostname

	You should see:

	  auth2.grpXX.dns.nsrc.org

	If not, then configure your server with its name: e.g. for
	auth2.grp25.dns.nsrc.org, type:

	 # hostname auth2.grp25.dns.nsrc.org

	Remember to replace "grpXX" with the the proper group number!

	Edit the file /etc/rc.conf (using "vi" or "ee", i.e.: ee /etc/rc.conf),
	and update the "hostname":

	  hostname="auth2.grpXX.dns.nsrc.org"

	In the file /etc/hosts, you should see a line:

	  10.10.X.2   auth2.grpXX auth2.grpXX.dns.nsrc.org

2. On AUTH2:

    # cd /usr/local/etc/nsd/

	Let's make a directory for slave zones to go into:

	# mkdir slave
	# chown nsd slave

	Let's copy the default configuration file:

    # cp nsd.conf.sample nsd.conf
	# chmod 644 nsd.conf

    Now edit the file nsd.conf, and make the following changes:

	- find the line:

		# ip-address: 12fe::8ef0

	and just below it add

		ip-address: 10.10.xx.2
		ip-address: 127.0.0.1

	- find the line:

		# database: "/var/db/nsd/nsd.db"

	and uncomment it (remove # in front):

		database: "/var/db/nsd/nsd.db"

	- find the line:
	
		# identity: "unidentified server"
	
	and change it to:

		identity: "nsd 4.1.1"

	- find the line:
	
		# zonesdir: "/usr/local/etc/nsd"

	and change it to:

		zonesdir: "/usr/local/etc/nsd"

	- find the line:

		# verbosity: 0
	
	and change it to:

		verbosity: 1
		
	Allow the nsd-control program to manage the server by adding:
	
	remote-control:
		control-enable: yes

	- Now let's add a slave for your TLD zone.  Insert the following lines,
	at the end of the file, replacing the appropriate values for your own
	zone:

- - - - - - - - - - - - - - - cut below - - - - - - - - - - - - - 
zone:
	name: "MYTLD"
	zonefile: "slave/MYTLD.zone"

	# Master server - replace X with the group of your master NS
	allow-notify: 10.10.X.1 NOKEY
	allow-notify: 127.0.0.1 NOKEY
	request-xfr: AXFR 10.10.X.1 NOKEY

- - - - - - - - - - - - - - - cut above - - - - - - - - - - - - - 


	- Save the file, exit

3. Setup the nsd-control program:

	# nsd-control-setup

4. Start NSD!

	- edit /etc/rc.conf and add:

    nsd_enable="YES"

    # service nsd restart 

	
5. Check the status and rebuild and reload NSD's base

	# nsd-control status
    # nsd-control write MYTLD
	# nsd-control reload

   Check the log file:
   
	# tail /var/log/daemon.log

   Check that the transfer has happened:
	
	# ls -l slave/

-rw-r--r--  1 root  wheel  414 Feb 17 07:28 MYTLD.zone

5. Test that your new secondary is answering:

	# dig @127.0.0.1 MYTLD SOA


6. If all is OK, add "auth2.grpXX.dns.nsrc.org" to your list of NSes in your
   zone on the AUTH1 host - remember the serial!


   ... when you modified the zone on AUTH1, it should have
   sent a notify to AUTH2 regarding the zone change, and AUTH2 should
   have picked up the new version.

   To verify that AUTH2 has picked up a new copy of the zone:

   # dig @auth2.grpX.dns.nsrc.org SOA MYTLD
   # dig @auth2.grpX.dns.nsrc.org NS MYTLD

   Make sure you see all NSes, including auth2.grpX !

   Q: What else do you need to do to make your new NS public ?
