2a31bd531072824ef252c18303859d6af7451b00Francis Dupont The best solution to solving installation and
2a31bd531072824ef252c18303859d6af7451b00Francis Dupont configuration issues is to take preventative measures by setting
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User up logging files beforehand. The log files provide a
28b3569d6248168e6c00caab951521cc8141a49dAutomatic Updater source of hints and information that can be used to figure out
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User what went wrong and how to fix the problem.

e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User Zone serial numbers are just numbers — they aren't
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User date related. A lot of people set them to a number that
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User represents a date, usually of the form YYYYMMDDRR.
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User Occasionally they will make a mistake and set them to a
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User "date in the future" then try to correct them by setting
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User them to the "current date". This causes problems because
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User serial numbers are used to indicate that a zone has been
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User updated. If the serial number on the slave server is
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User lower than the serial number on the master, the slave
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User server will attempt to update its copy of the zone.

fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User server than the slave server means that the slave will not perform
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater updates to its copy of the zone.
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User The solution to this is to add 2147483647 (2^31-1) to the
e62b9c9ce6413fb183c8116381e75dcd07ca5517Tinderbox User number, reload the zone and make sure all slaves have updated to
8ec3c085233cedb22b05da36e2773c8f357a7e45Automatic Updater the new zone serial number, then reset the number to what you want
6ea2385360e9e2167e65f9286447da9eea189457Tinderbox User it to be, and reload the zone again.
