=head1 nsdiff =head2 create an "nsupdate" script from DNS zone file differences The B program examines the old and new versions of a DNS zone, and outputs the differences as a script for use by BIND's B program. It provides a bridge between static zone files and dynamic updates. The B script is a wrapper around C that checks and reports errors in a manner suitable for running from B. The B script makes it easy to edit a dynamic zone. =over I - JP Mens =back If you use BIND 9.7 or 9.8, you can use B as an alternative to the DNSSEC C feature which appeared in BIND 9.9. The server updates the DNSSEC records dynamically, but you can continue to manage the unsigned static zone file as before and use C<`nsdiff | nsupdate`> to push changes to the server. There are other situations where you have a zone which is partly dynamic and partly static, for example, a reverse DNS zone mostly updated by a DHCP server, which also has a few static entries. You can use B to update the static part of the zone. =head2 Dependencies To run nsdiff you need perl-5.10 or newer, and BIND version 9.7 or newer, specifically the B, B, and B utilities. =head2 Install To install, run: perl Makefile.PL make install To install in a particular place, use something like perl Makefile.pl PREFIX=${HOME} =head2 Downloads =over =item Documentation The nsdiff homepage is L Read the nsdiff manual: L Read the nspatch manual: L Read the nsvi manual: L =item Code Download the bare nsdiff perl source: L Download the source distribution: =over =item L =back =item Source repositories You can clone or browse the repository from: =over =item L =item L =item L =item L =back =back =head2 Feedback Please send bug reports or patches to me at .
