ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User The best solution to solving installation and
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User configuration issues is to take preventative measures by setting
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User up logging files beforehand. The log files provide a
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User source of hints and information that can be used to figure out
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein what went wrong and how to fix the problem.

ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User Zone serial numbers are just numbers — they aren't
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein date related. A lot of people set them to a number that
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein represents a date, usually of the form YYYYMMDDRR.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Occasionally they will make a mistake and set them to a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein "date in the future" then try to correct them by setting
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein them to the "current date". This causes problems because
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User serial numbers are used to indicate that a zone has been
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User updated. If the serial number on the slave server is
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein lower than the serial number on the master, the slave
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User server will attempt to update its copy of the zone.
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User Setting the serial number to a lower number on the master
ea94d370123a5892f6c47a97f21d1b28d44bb168Tinderbox User server than the slave server means that the slave will not perform
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein updates to its copy of the zone.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The solution to this is to add 2147483647 (2^31-1) to the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein number, reload the zone and make sure all slaves have updated to
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the new zone serial number, then reset the number to what you want
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein it to be, and reload the zone again.
