ldns-notify - Man Page

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.

-I address

Source IP to send query from.


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[:algo]

Use the given TSIG key and base64-data, and optionally an algorithm to sign the NOTIFY. The algorithm defaults to hmac-md5.sig-alg.reg.int.


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.

Exit Code

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