NSD usage

NSD
1

Hi list,

after converting the djbdns-zonefile to
something NSD can read, I wonder about
the updating process. Currently I'm
doing something like this:

- - creating the zone: statements on the
  master and the slave in nsd.conf
- - create the zonefile referenced in the
  nsd.conf zone: statement on the master
- - do a nsdc rebuild && nsdc restart && nsdc notify

The slave has as per recommendation a
'nsdc patch' in it's crontab.

Is there a different way or does it need
to be done like that?

Also, I intentionally fubared the nsd.db
file, to see how it can be fixed. How do
I restore that file if it's gone/screwed?

Thanks and best regards,

Mit freundlichen Gruessen,

i. A. Sven Juergensen

- - do a nsdc rebuild && nsdc restart && nsdc notify

nsd-3 should no longer requires seperate nsdc notify commands.
nsd-2 requires tehse.

file, to see how it can be fixed. How do
I restore that file if it's gone/screwed?

Handling of a broken/missing nsd.db file could probably improve :slight_smile:

NSD keeps a journal in ixfr.db. If you don't run nsdc patch once in a
while, it may grow 'indefinitely' large.

Run nsdc rebuild again. You can use the nsd-xfer program to transfer the
zones you are secondary for.
