ldns-notify(1) notify DNS servers that updates are available


ldns-notify [options] -z zone servers


ldns-notify sends a NOTIFY message to DNS servers. This tells them that an updated zone is available at the master servers. It can perform TSIG signatures and it can add a SOA serial number of the updated zone. If a server already has that serial number it will disregard the message.


-z zone
The zone that is updated.

Show usage and exit

Show the version and exit

-s serial
Append a SOA record indicating the serial number of the updated zone.

-p port
Use port as destination port (default the DNS port 53) for the UDP packets.

-y key:data
Use the given TSIG key and base64-data to sign the NOTIFY. Uses the hmac-md5 algorithm.

Print verbose debug information. The query that is sent and the query that is received.

-r num
Specify the maximum number of retries before notify gives up trying to send the UDP packet.


The program exits with a 0 exit code if all servers replied an acknowledgement to the notify message, and a failure exit code otherwise.
