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

Zone serial numbers are just numbers — they aren't
|
|
|
|
|
|
date related. A lot of people set them to a number that
|
|
|
|
|
|
represents a date, usually of the form YYYYMMDDRR.
|
|
|
|
|
|
Occasionally they will make a mistake and set them to a
|
|
|
|
|
|
"date in the future" then try to correct them by setting
|
|
|
|
|
|
them to the "current date". This causes problems because
|
|
|
|
|
|
serial numbers are used to indicate that a zone has been
|
|
|
|
|
|
updated. If the serial number on the slave server is
|
|
|
|
|
|
lower than the serial number on the master, the slave
|
|
|
|
|
|
server will attempt to update its copy of the zone.

|
|
|
|
|
|
<p>
|
|
|
|
|
|
Setting the serial number to a lower number on the master
|
|
|
|
|
|
server than the slave server means that the slave will not perform
|
|
|
|
|
|
updates to its copy of the zone.
|
|
|
|
|
|
</p>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
The solution to this is to add 2147483647 (2^31-1) to the
|
|
|
|
|
|
number, reload the zone and make sure all slaves have updated to
|
|
|
|
|
|
the new zone serial number, then reset the number to what you want
|
|
|
|
|
|
it to be, and reload the zone again.
