NSD and OpenDNSSEC under FreeBSD 10 [Part 3: OpenDNSSEC]

This is the third part in the series of articles explaining how to run NSD and OpenDNSSEC under FreeBSD 10.

In this exercise we’re going to configure our signing server NS-SIGN which will be running OpenDNSSEC with DNSSEC keys stored in SoftHSM.

For the sake of simplicity, let’s assume we’re going to host a zone called signed.org.

Go to NS-FEED and generate new TSIG which will be used for the new zone transfers:

  1. % cd /usr/local/etc/nsd
  2. % dnssec-keygen -a HMAC-SHA256 -b 256 -n HOST ns-feed-signed
  3. % cat Kns-feed-signed.+163+18286.key
  4.  
  5. ns-feed-signed. IN KEY 512 3 163 8X/kvc25+9G1igCCpuuFf9sES0P+gryldjeIgA700Gw=

Add a new TSIG key and zone directives. Here is an updated nsd.conf of our hidden master:

  1. server:
  2.         ip-address: 10.9.128.1
  3.         do-ip4: yes
  4.         do-ip6: no
  5.         verbosity: 2
  6.         chroot: "/usr/local/etc/nsd"
  7.         zonesdir: "/usr/local/etc/nsd"
  8.         zonelistfile: "zone.list"
  9.         database: "var/db/nsd/nsd.db"
  10.         logfile: "var/log/nsd.log"
  11.         pidfile: "var/run/nsd.pid"
  12.         xfrdfile: "var/db/nsd/xfrd.state"
  13.         xfrdir: "var/db/nsd/"
  14.         hide-version: yes
  15.  
  16. remote-control:
  17.         control-enable: yes
  18.         control-interface: 127.0.0.1
  19.         control-port: 8952
  20.         server-key-file: "/usr/local/etc/nsd/nsd_server.key"
  21.         server-cert-file: "/usr/local/etc/nsd/nsd_server.pem"
  22.         control-key-file: "/usr/local/etc/nsd/nsd_control.key"
  23.         control-cert-file: "/usr/local/etc/nsd/nsd_control.pem"
  24.  
  25. key:
  26.         name: "tsig.sha256.plain"
  27.         algorithm: hmac-sha256
  28.         secret: "IseujRBzonAlWpVBLyyvn6ErSTp/CGui6+RIeXXLxb4="
  29.  
  30. key:
  31.         name: "tsig.sha256.signed"
  32.         algorithm: hmac-sha256
  33.         secret: "8X/kvc25+9G1igCCpuuFf9sES0P+gryldjeIgA700Gw="
  34.  
  35. pattern:
  36.         name: "plain-to-slaves"
  37.         zonefile: "zones/%s"
  38.         notify: 192.168.128.1 tsig.sha256.plain
  39.         notify: 192.168.128.2 tsig.sha256.plain
  40.         provide-xfr: 192.168.128.1-192.168.128.2 tsig.sha256.plain
  41.  
  42. pattern:
  43.         name: "plain-to-signer"
  44.         zonefile: "zones/%s"
  45.         notify: 10.9.128.2 tsig.sha256.signed
  46.         provide-xfr: 10.9.128.2 tsig.sha256.signed
  47.  
  48. zone:
  49.         name: "plain.org"
  50.         include-pattern: "plain-to-slaves"
  51.  
  52. zone:
  53.         name: "signed.org"
  54.         include-pattern: "plain-to-signer"

As you can see there is a new key directive, new pattern and a new zone added.

Create a file called signed.org under /usr/local/etc/nsd/zones directory:

  1.  
  2. $ORIGIN signed.org.
  3. $TTL 1h
  4. @       IN      SOA     signed.org.      hostmaster.signed.org. (
  5.                         2014082701              ; serial number
  6.                         3600                    ; refresh
  7.                         900                     ; retry
  8.                         1209600                 ; expire
  9.                         1800                    ; ttl
  10.                         )
  11. ; Name servers
  12.                     IN      NS      ns1.signed.org.
  13.                     IN      NS      ns2.signed.org.
  14.  
  15. ; A records for name servers
  16. ns1                 IN      A       192.168.128.1
  17. ns2                 IN      A       192.168.128.2
  18.  
  19. ; Additional A records
  20. @                   IN      A       192.168.128.20
  21. www                 IN      A       192.168.128.20

Reload the config of NSD so that the new zone is served:

  1. % nsd-control reconfig

Verify that you can query it:

  1.  
  2. % dig @10.9.128.1 signed.org soa
  3.  
  4. ; <<>> DiG 9.10.0-P2 <<>> @10.9.128.1 signed.org soa

Go to NS-SIGN and install required software:

  1. % cd /usr/ports/dns/opendnssec && make install clean

Ensure that SOFTHSM is checked. Since I’m not going to use MySQL I select SQLITE as a DB backend.

Modify /etc/rc.conf to start OpenDNSSEC at boot:

  1. # enable opendnssec
  2. opendnssec_enable="YES"

Initialize SoftHSM database with the label “OpenDNSSEC”. You will be prompted to provide with two PINs: SO PIN and user PIN. Note and keep both PINs in a secure place. The SO PIN can be used to reinitialize the token and the user PIN will be used by OpenDNSSEC to interact with the token.

  1. % softhsm —-init-token —-slot 0 —-label "OpenDNSSEC"
  2.  
  3.     The SO PIN must have a length between 4 and 255 characters.
  4.     Enter SO PIN: ****
  5.     The user PIN must have a length between 4 and 255 characters.
  6.     Enter user PIN: ****
  7.     The token has been initialized.

Confirm that the slot has been initialized and available as per the config:

  1. % softhsm —-show-slots
  2.  
  3. Available slots:
  4. Slot 0
  5.            Token present: yes
  6.            Token initialized: yes
  7.            User PIN initialized: yes
  8.            Token label: OpenDNSSEC
  9.  
  10. % cat /usr/local/etc/softhsm.conf
  11. 0:/var/lib/softhsm/slot0.db
  12.  
  13. % ls -al /var/lib/softhsm/slot0.db
  14. -rw——-  1 root  wheel  45056 Aug 28 18:14 /var/lib/softhsm/slot0.db

Create config files for OpenDNSSEC:

  1. % cd /usr/local/etc/opendnssec
  2.  
  3. % cp addns.xml.sample addns.xml
  4. % cp conf.xml.sample conf.xml
  5. % cp kasp.xml.sample kasp.xml
  6. % cp zonelist.xml.sample zonelist.xml

addns.xml is the config file where you define zone transfer settings or so called DNS adapters. I removed comments and examples so it could be easier to read it:

As you can see, we defined our TSIG that is used for signed zones. Inbound container contains the server where we get the plain zone from — this is our hidden master NS-FEED. Outbound container contains servers where we send the zone after it has been signed — these are our public slaves: NS-3 and NS-4.

conf.xml is the overall config file of OpenDNSSEC where you define global settings, like system paths, logging, key repositories and etc.

  1. <?xml version="1.0" encoding="UTF-8"?>

  43.

Mainly all settings are as per the default file. Don’t forget to enter proper User PIN. The only thing I modified was the IP address under Listener container. This file will give you an idea about system paths where SQLite DB and working files are stored, which is useful during troubleshooting.

kasp.xml is a pretty important file where you define policies used to sign zones, for example, security parameters (algorithm, key size) and timing parameters (when the zone is supposed to be resigned and such):

  1. <?xml version="1.0" encoding="UTF-8"?>
  2.  
  3. <KASP>
  4.  
  5.         <Policy name="default">
  6.                 <Description>A default policy that will amaze you and your friends</Description>

I accepted the default policy called default. As per this policy, the lifetime of KSK is 1 year and the lifetime of ZSK is 90 days. The only thing I changed was the Serial container: changed to datecounter.

Finally, zonelist.xml is a file where you add your zone:

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <ZoneList>
  3.         <Zone name="signed.org">
  4.                 <Policy>default</Policy>
  5.                 <SignerConfiguration>/usr/local/var/opendnssec/signconf/signed.org.xml</SignerConfiguration>
  6.                 <Adapters>
  7.                         <Input>
  8.                                 <Adapter type="DNS">/usr/local/etc/opendnssec/addns.xml</Adapter>
  9.                         </Input>
  10.                         <Output>
  11.                                 <Adapter type="DNS">/usr/local/etc/opendnssec/addns.xml</Adapter>
  12.                         </Output>
  13.                 </Adapters>
  14.         </Zone>
  15. </ZoneList>

Note that we’re using DNS adapter, which means that OpenDNSSEC won’t expect any files as a source, but rather sign the zone it will get from our hidden master.

  2.  
  3. SQLite database set to: /usr/local/var/opendnssec/kasp.db
  4. Keys:

The important part here is the State column: our KSK key is in Publish state, which means it has been published in the zone, but it’s not yet ready to be used (it hasn’t been long enough in the zone to propagate). We have to wait till the next transition cycle, which will transfer our KSK to Ready state, and after that, we will be able to export the key and DS records.

You can also check the log files:

  1. % tail /var/log/messages
  2.  
  3. Aug 29 22:16:28 ns-sign ods-enforcerd: WARNING: KSK rollover for zone 'signed.org' not completed as there are no keys in the 'ready' state; ods-enforcerd will try again when it runs next

Let’s check the status after several hours:

  1. % ods-ksmutil key list —-zone signed.org —-verbose
  2.  
  3. SQLite database set to: /usr/local/var/opendnssec/kasp.db

  3. Aug 30 12:16:31 ns-sign ods-enforcerd: WARNING: New KSK has reached the ready state; please submit the DS for signed.org and use ods-ksmutil key ds-seen when the DS appears in the DNS.

Great — the status has changed to Ready, which means we’re ready to extract DS records for our domain:

  1. % ods-ksmutil key export —-zone signed.org —-ds —-keystate READY
  2.  
  3. ;ready KSK DS record (SHA1):
  4. signed.org. 3600    IN      DS      44774 8 1 6af6caff1d7cb20c48cb240a40322103a18c4ef3
  5.  
  6. ;ready KSK DS record (SHA256):
  7. signed.org. 3600    IN      DS      44774 8 2 3c177857ccae27674f51cf233dc935d3d678769901fce8c623ea85184a6d40b6

Send both DS records to the registrar so that the chain is trusted. Once the new DSs are entered on the registrar side, complete the roll-over:

  1. % ods-ksmutil key ds-seen -z signed.org -x 44774
  2.  
  3. Found key with CKA_ID a502e7cae0ed679efc52436d7b8703fd
  4. Key a502e7cae0ed679efc52436d7b8703fd made active
  5. Notifying enforcer of new database…
  6. Performed a HUP ods-enforcerd

Where 44774 is the keytag of our zone.

The KSK key is now in active state and we finished with NS-SIGN!

  1. % ods-ksmutil key list —-zone signed.org —-verbose

The only thing that is still pending is the configuration of NS-3 and NS-4 to host our new signed zone. Here is the updated nsd.conf of NS-3 reflecting signed.org. Repeat the same on NS-4.

  1. server:
  2.         ip-address: 192.168.128.1
  3.         do-ip4: yes
  4.         do-ip6: no

  10.         logfile: "var/log/nsd.log"
  11.         pidfile: "var/run/nsd.pid"
  12.         xfrdfile: "var/db/nsd/xfrd.state"
  13.         xfrdir: "var/db/nsd/"
  14.         hide-version: yes
  15.  
  16. remote-control:
  17.         control-enable: yes

  24.  
  25. key:
  26.         name: "tsig.sha256.plain"
  27.         algorithm: hmac-sha256
  28.         secret: "IseujRBzonAlWpVBLyyvn6ErSTp/CGui6+RIeXXLxb4="
  29.  
  30. key:
  31.         name: "tsig.sha256.signed"
  32.         algorithm: hmac-sha256
  33.         secret: "8X/kvc25+9G1igCCpuuFf9sES0P+gryldjeIgA700Gw="
  34.  
  35. pattern:
  36.         name: "from-master"
  37.         zonefile: "zones/%s"
  38.         request-xfr: AXFR 10.9.128.1 tsig.sha256.plain
  39.         provide-xfr: 172.16.128.1 tsig.sha256.plain
  40.         allow-notify: 10.9.128.1 tsig.sha256.plain
  41.         notify: 172.16.128.1 tsig.sha256.plain
  42.  
  43. pattern:
  44.         name: "from-signer"
  45.         zonefile: "zones/%s"
  46.         request-xfr: AXFR 10.9.128.2 tsig.sha256.signed
  47.         provide-xfr: 172.16.128.1 tsig.sha256.signed
  48.         allow-notify: 10.9.128.2 tsig.sha256.signed
  49.         notify: 172.16.128.1 tsig.sha256.signed
  50.  
  51. zone:
  52.         name: "plain.org"
  53.         include-pattern: "from-master"
  54.  
  55. zone:
  56.         name: "signed.org"
  57.         include-pattern: "from-signer"

You can now add a new DNS record in signed.org zone, increase the serial and reload the zone (all to be done on NS-FEED). The record will be automatically signed by NS-SIGN and the zone transferred to NS-3/4.

Thanks for reading! The setup is completed.
