* Package name : nsnotifyd Version : 2.3 Upstream Contact: Tony Finch <d...@dotat.at> * URL : https://dotat.at/prog/nsnotifyd/ * License : 0BSD OR MIT-0 Programming Lang: C, Shell Description : promply run a command on DNS zone changes The nsnotifyd daemon monitors a set of DNS zones and runs a command when any of them change. It listens for DNS NOTIFY messages so it can respond to changes promptly. It also uses each zone's SOA refresh and retry parameters to poll for updates if nsnotifyd does not receive NOTIFY messages more frequently. Anywhere you currently have a cron job which is monitoring updates to DNS zones, you might want to run it under nsnotifyd instead of cron, so your script runs as soon as the zone changes instead of running at fixed intervals. There is also a client program nsnotify for sending notify messages. ### Examples There are four example scripts included and described in the manual: - metazone - allows you to use standard DNS mechanisms - AXFR, IXFR, NOTIFY, UPDATE -- to control the configuration of multiple name servers, instead of using a separate out-of-band distribution system. - nsnotify2git - records the history of changes to a set of zones. - nsnotify2stealth - uses nsnotify-liststealth and nsnotify to notify stealth secondaries so they get updates faster. - nsnotify2update - uses nsdiff and nsupdate as part of a bump-in-the-wire DNSSEC signer. --- I have this crazy idea to use this for DNS-SD style Wireguard mesh managment. Think: pushing wg config to many machines by updating DNS :-) Even outside such crazy this package seems exceedingly useful for anyone dealing with DNS. The git support feels similar to etckeeper which people seem to enjoy. Maybe I should look into adding 'zonekeeper' to integrate with a locally running nameserver by default? I intend to maintain it myself, but as always co-maintainers are welcome. --Daniel
