[[:TuxSoftware]]

On the old machine, named runs as nobody. On the new machine, it installed wanting to run as bind. We can accept this change.

The pid-file has moved - we can accept this change.

bind9 runs, and tries to send notifies.

dig returns the right ip address (ie, the address of the real tux)

Seems good enough.

  * refresh:

Secondaries check every <refresh> seconds, whether the SOA on the primary has changed. If yes, a zone transfer is done.

  * retry:

A secondary having been unable to do a zone transfer because of unreachable of the primary retries every <retry> seconds.

  * expire:

The zone's information is considered invalid by the secondary if the primary could not be reached for <expire> seconds.

  * minimum TTL:

This is the default value for all records in the zone file which can be overriden by values for the individual records. After <minimum TTL> seconds, the zone information on the caching nameserver becomes invalid and has to be re-fetched from an authoritative server. NOTE: This field was intended to be a minimum value for all records in the zone but is now widely implemented as giving the default.
