0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews The best solution to solving installation and
0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews configuration issues is to take preventative measures by setting
0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews up logging files beforehand. The log files provide a
0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews source of hints and information that can be used to figure out
9513a2a6670951f5cf5477fcfec9f933fcaff628Automatic Updater what went wrong and how to fix the problem.

0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews Zone serial numbers are just numbers — they aren't
0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews date related. A lot of people set them to a number that
0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews represents a date, usually of the form YYYYMMDDRR.
0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews Occasionally they will make a mistake and set them to a
015055b6e23f5c08f6a5b34726f90b62597e9e45Tinderbox User "date in the future" then try to correct them by setting
2ae159b376dac23870d8005563c585acf85a4b5aEvan Hunt them to the "current date". This causes problems because
2ae159b376dac23870d8005563c585acf85a4b5aEvan Hunt serial numbers are used to indicate that a zone has been
2ae159b376dac23870d8005563c585acf85a4b5aEvan Hunt updated. If the serial number on the slave server is
95637507c3d47481fbf0a8a8c750a57f944f677fMark Andrews lower than the serial number on the master, the slave
2ae159b376dac23870d8005563c585acf85a4b5aEvan Hunt server will attempt to update its copy of the zone.
2ae159b376dac23870d8005563c585acf85a4b5aEvan Hunt Setting the serial number to a lower number on the master
2ae159b376dac23870d8005563c585acf85a4b5aEvan Hunt server than the slave server means that the slave will not perform
2ae159b376dac23870d8005563c585acf85a4b5aEvan Hunt updates to its copy of the zone.
dedefc0bdbb4e6e39eeb98aa2fc6883efec2ddb0Mark Andrews The solution to this is to add 2147483647 (2^31-1) to the
c651f15b30f1dae5cc2f00878fb5da5b3a35a468Mark Andrews number, reload the zone and make sure all slaves have updated to
950d203b64f512b85fcc093ee1e9e3e531a1aea3Tinderbox User the new zone serial number, then reset the number to what you want
27739dd25026283c24645c8a1044b95ef9eb5ac6Tinderbox User it to be, and reload the zone again.
