fanfI have made
a new release of nsnotifyd
a tiny DNS server that just listens for NOTIFY messages
and runs a script when one of your zones changes.
This nsnotifyd-2.0 release adds support for TCP. The
original nsnotifyd only supported UDP, which works fine with BIND,
but Knot DNS sends NOTIFY messages over
TCP.
As well as its new TCP support, the nsnotify client program that sends
NOTIFY messages can now send bulk notifications for lots of zones, as
well as being able to send notifications to lots of recipient servers.
Many thanks to Niels Haarbo and DK Hostmaster for requesting TCP support and for sponsoring my work to implement it.
I like nsnotifyd because I wrote it in 2015, and I haven’t touched
it since then (until this month). I usually hear nothing about
nsnotifyd, but occasionally someone mentions they are using it. For
example the Guardian tech blog said of nsnotifyd, "like all
good *nix tools it does one thing well", and JP Mens called it "a
gem of a utility".
Happy users, no bug reports, software bliss.
