46472a450e043434d78fa18edc73bca8c47f3981Tinderbox User The best solution to solving installation and
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt configuration issues is to take preventative measures by setting
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User up logging files beforehand. The log files provide a
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User source of hints and information that can be used to figure out
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt what went wrong and how to fix the problem.

14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt Zone serial numbers are just numbers — they aren't
a1ff871f78b7d907d6fc3a382beea2a640fe8423Tinderbox User date related. A lot of people set them to a number that
a1ff871f78b7d907d6fc3a382beea2a640fe8423Tinderbox User represents a date, usually of the form YYYYMMDDRR.
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User Occasionally they will make a mistake and set them to a
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User "date in the future" then try to correct them by setting
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User them to the "current date". This causes problems because
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User serial numbers are used to indicate that a zone has been
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User updated. If the serial number on the slave server is
a1ff871f78b7d907d6fc3a382beea2a640fe8423Tinderbox User lower than the serial number on the master, the slave
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User server will attempt to update its copy of the zone.
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User Setting the serial number to a lower number on the master
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User server than the slave server means that the slave will not perform
a1ff871f78b7d907d6fc3a382beea2a640fe8423Tinderbox User updates to its copy of the zone.
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User The solution to this is to add 2147483647 (2^31-1) to the
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User number, reload the zone and make sure all slaves have updated to
a1ff871f78b7d907d6fc3a382beea2a640fe8423Tinderbox User the new zone serial number, then reset the number to what you want
8a48b6b9b6fa8486f24b22d1972b2b6ebb36a4a4Tinderbox User it to be, and reload the zone again.
