7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User The best solution to solving installation and
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User configuration issues is to take preventative measures by setting
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User up logging files beforehand. The log files provide a
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User source of hints and information that can be used to figure out
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User what went wrong and how to fix the problem.

1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User Zone serial numbers are just numbers — they aren't
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User date related. A lot of people set them to a number that
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User represents a date, usually of the form YYYYMMDDRR.
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User Occasionally they will make a mistake and set them to a
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User "date in the future" then try to correct them by setting
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User them to the "current date". This causes problems because
7e71f05d8643aca84914437c900cb716444507e4Tinderbox User serial numbers are used to indicate that a zone has been
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User updated. If the serial number on the slave server is
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User lower than the serial number on the master, the slave
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User server will attempt to update its copy of the zone.
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User Setting the serial number to a lower number on the master
bfb7b680bf88c1fdd9949197b71c512c532280a4Tinderbox User server than the slave server means that the slave will not perform
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User updates to its copy of the zone.
bfb7b680bf88c1fdd9949197b71c512c532280a4Tinderbox User The solution to this is to add 2147483647 (2^31-1) to the
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User number, reload the zone and make sure all slaves have updated to
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User the new zone serial number, then reset the number to what you want
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User it to be, and reload the zone again.
