This section describes how to start OpenDNSSEC and the operations used to manage and monitor the system.
The details of the command utilities shown below can be found here.

All directories are prepared by the build script and are set to be owned by root, so all commands in the default configuration must also be run by root. To change this, alter the configuration or privileges on the files and directories.
Before you run the system for the first time you must import your policy and zone list into the database using the following command:
ods-ksmutil setup
After running this the first time, you will be ready to run OpenDNSSEC with an empty set of zones. On the other hand, if this command is run on an existing database, then will all meta-information about the zones be lost. The keys would then still exist in HSMs, so you should not forget to clean them up.
If the PIN to the HSM is not in conf.xml, then it must be entered by the user with the following command:
ods-hsmutil login
If the PIN has not been entered before OpenDNSSEC is started, then the daemons will not start.
There are strict privilege control on the shared memory segment containing the PIN, so remember to run commands and processes with the correct privileges. If the daemons are dropping privileges, then you also need to run ods-hsmutil with the correct user and group.
$ sudo -u <user> -g <group> ods-hsmutil login
If you experience trouble please see Troubleshooting.
OpenDNSSEC consist of two daemons, ods-signerd and ods-enforcerd. To start and stop them use the following commands:
ods-control start
A proper-looking response to this commands is:
Starting enforcer... OpenDNSSEC ods-enforcerd started (version 1.4.0), pid 31937 Starting signer... OpenDNSSEC signer engine version 1.4.0 Engine running.
At any time, you can stop OpenDNSSEC's daemons orderly with:
ods-control stop
After this, your logs should contain messages like:
Stopping enforcer... Stopping signer engine... Engine shut down.
Your zone will be signed, once you have setup the system and started it. When you have verified that the zone is operational and working, it is time to upload the trust anchor to the parent zone. The Enforcer is waiting for zone to be connected to the trust chain before considering the KSK to be active.

Export the public key either as DNSKEY or DS, depending on what format your parent zone wants it in. See the section, Export the public keys, on how to get the key information.
This step can be automated or semi-automated by placing a command in the <DelegationSignerSubmitCommand> tag. This should point to a binary which will accept the required key(s) as DNSKEY RRs on STDIN.
Notify the Enforcer when you can see the DS RR in your parent zone. You usually give the keytag to the Enforcer, but if there are KSKs with the same keytag then use the CKA_ID.
ods-ksmutil key ds-seen -z example.com -x 22499
or
ods-ksmutil key ds-seen -z example.com -k 9621ca39306ce050e8dd94c5ab837001
Result: Found key with CKA_ID 9621ca39306ce050e8dd94c5ab837001 Key 9621ca39306ce050e8dd94c5ab837001 made active
And you will see that your KSK is now active:

When you update the content of an unsigned zone you must manually tell the signer engine to re-read the unsigned zone file using the ods-signer command like this:
ods-signer sign example.com
When you make changes to the enforcer section of conf.xml, kasp.xml or zonelist.xml you must run the
ods-ksmutil update all
command (or the appropriate command listed below) in order for the changes to be propagated to the system database.
If you make changes to the enforcer section of the conf.xml file then you must run
ods-ksmutil update conf
For most other changes to the conf.xml file it is advisable to stop and start OpenDNSSEC to ensure the changes are detected.
When you make changes to a policy or add a new policy in kasp.xml you must update the changes to the database.
ods-ksmutil update kasp
When making changes to the KASP policy the following should also be considered:
After updating signature timers in the policy it may be helpful to issue the command:
$ ods-signer clear <zone>; ods-signer sign <zone>
as it will speed up acclimatising timers for the signatures.
If you add zones directly into the zonelist (rather than using the ods-ksmutil zone add command) you must tell the enforcer to re-read the zone list by using the command:
ods-ksmutil update zonelist
Details of logs produced by the system can be found on the Logging page.
$ ods-signer clear <zone>; ods-signer sign <zone>
