af0732a2bf24fbea12a085b855224577e7101851kiirala The best solution to solving installation and
af0732a2bf24fbea12a085b855224577e7101851kiirala configuration issues is to take preventative measures by setting
af0732a2bf24fbea12a085b855224577e7101851kiirala up logging files beforehand. The log files provide a
af0732a2bf24fbea12a085b855224577e7101851kiirala source of hints and information that can be used to figure out
af0732a2bf24fbea12a085b855224577e7101851kiirala what went wrong and how to fix the problem.

af0732a2bf24fbea12a085b855224577e7101851kiirala Zone serial numbers are just numbers — they aren't
af0732a2bf24fbea12a085b855224577e7101851kiirala date related. A lot of people set them to a number that
af0732a2bf24fbea12a085b855224577e7101851kiirala represents a date, usually of the form YYYYMMDDRR.
af0732a2bf24fbea12a085b855224577e7101851kiirala Occasionally they will make a mistake and set them to a
af0732a2bf24fbea12a085b855224577e7101851kiirala "date in the future" then try to correct them by setting
af0732a2bf24fbea12a085b855224577e7101851kiirala them to the "current date". This causes problems because
af0732a2bf24fbea12a085b855224577e7101851kiirala serial numbers are used to indicate that a zone has been
af0732a2bf24fbea12a085b855224577e7101851kiirala updated. If the serial number on the slave server is
af0732a2bf24fbea12a085b855224577e7101851kiirala lower than the serial number on the master, the slave
af0732a2bf24fbea12a085b855224577e7101851kiirala server will attempt to update its copy of the zone.
af0732a2bf24fbea12a085b855224577e7101851kiirala Setting the serial number to a lower number on the master
af0732a2bf24fbea12a085b855224577e7101851kiirala server than the slave server means that the slave will not perform
af0732a2bf24fbea12a085b855224577e7101851kiirala updates to its copy of the zone.
d9a7c806ee7f408ddb61ff4f233c9d96111ee2b5johanengelen The solution to this is to add 2147483647 (2^31-1) to the
af0732a2bf24fbea12a085b855224577e7101851kiirala number, reload the zone and make sure all slaves have updated to
af0732a2bf24fbea12a085b855224577e7101851kiirala the new zone serial number, then reset the number to what you want
af0732a2bf24fbea12a085b855224577e7101851kiirala it to be, and reload the zone again.
