14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt The best solution to solving installation and
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater configuration issues is to take preventative measures by setting
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater 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.

7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User Zone serial numbers are just numbers — they aren't
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater date related. A lot of people set them to a number that
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater represents a date, usually of the form YYYYMMDDRR.
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater Occasionally they will make a mistake and set them to a
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater "date in the future" then try to correct them by setting
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater them to the "current date". This causes problems because
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater serial numbers are used to indicate that a zone has been
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater updated. If the serial number on the slave server is
cd32f419a8a5432fbb139f56ee73cbf68b9350ccTinderbox User lower than the serial number on the master, the slave
10b865e9187fc77cae02f106ddcc9e03eecdfe06Tinderbox User server will attempt to update its copy of the zone.
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater Setting the serial number to a lower number on the master
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater server than the slave server means that the slave will not perform
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater updates to its copy of the zone.
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater The solution to this is to add 2147483647 (2^31-1) to the
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater number, reload the zone and make sure all slaves have updated to
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater the new zone serial number, then reset the number to what you want
fc2381b901eb162810f54a11cc512b95f55a60dfAutomatic Updater it to be, and reload the zone again.
