nsnotifyd-2.1 released

I 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-2.1 release includes a few bugfixes:

more lenient handling of trailing . in domain names on the command line
avoid dividing by zero when the refresh interval is less than 10 seconds
do not error out when in TCP mode and debug mode and the refresh timer expires
explain how to fix incomplete github forks

Many thanks to Lars-Johann Liman, JP Mens, and Jonathan Hewlett for the bug reports. I like receiving messages that say things like,

thanks for nsnotifyd, is a great little program, and a good example of a linux program, does one thing well.

(There’s more like that in the nsnotifyd-2.0 release annoucement.)

I have also included a little dumpaxfr program, which I wrote when fiddling around with binary wire format DNS zone transfers. I used the nsnotifyd infrastructure as a short cut, though dumpaxfr doesn’t logically belong here. But it’s part of the family, so I wrote a dumpaxfr(1) man page and included it in this release.

I will be surprised if anyone else finds dumpaxfr useful!
