7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User The best solution to solving installation and
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User configuration issues is to take preventative measures by setting
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User 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.

14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt Zone serial numbers are just numbers — they aren't
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews date related. A lot of people set them to a number that
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews represents a date, usually of the form YYYYMMDDRR.
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt Occasionally they will make a mistake and set them to a
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt "date in the future" then try to correct them by setting
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews them to the "current date". This causes problems because
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt serial numbers are used to indicate that a zone has been
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews updated. If the serial number on the slave server is
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews lower than the serial number on the master, the slave
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt server will attempt to update its copy of the zone.
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User Setting the serial number to a lower number on the master
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User server than the slave server means that the slave will not perform
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User updates to its copy of the zone.
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User The solution to this is to add 2147483647 (2^31-1) to the
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User number, reload the zone and make sure all slaves have updated to
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews the new zone serial number, then reset the number to what you want
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews it to be, and reload the zone again.
