NAME

ldns-notify - notify DNS servers that updates are available

SYNOPSIS

ldns-notify [options] -z zone servers

DESCRIPTION

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.

OPTIONS

-z zone: The zone that is updated.
-I address: Source IP to send query from.
-h: Show usage and exit
-v: 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.
-d: 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.
