ldns-notify
ldns-notify(1) General Commands Manual ldns-notify(1)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.
-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
Use the given TSIG key and base64-data to sign the NOTIFY. Uses the hmac-md5 algorithm.
-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.
