nsnotify — send DNS NOTIFY messages

nsnotify [-46dtV] [-s addr] [-p port] ⟨zone⟩ ⟨target⟩...

nsnotify [-46dtV] [-s addr] [-p port] -F zones ⟨target⟩...

nsnotify [-46dtV] [-s addr] [-p port] -f targets ⟨zones⟩...

nsnotify [-46dtV] [-s addr] [-p port] -F zones -f targets

The nsnotify program sends DNS NOTIFY messages for a list of zones to a list of targets. You can either provide a list of targets on the command line, or use the -f targets option to read from a file. To send a notifications about more than one zone, you can use the -F zones option to read from a file.

Note: nsnotify (without ‘d’) is a client for sending DNS NOTIFY messages whereas nsnotifyd (with ‘d’) is a daemon for handling DNS NOTIFY messages.
