487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence The best solution to solving installation and
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence configuration issues is to take preventative measures by setting
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence up logging files beforehand. The log files provide a
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence source of hints and information that can be used to figure out
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence what went wrong and how to fix the problem.

487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence Zone serial numbers are just numbers — they aren't
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence date related. A lot of people set them to a number that
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence represents a date, usually of the form YYYYMMDDRR.
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence Occasionally they will make a mistake and set them to a
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence "date in the future" then try to correct them by setting
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence them to the "current date". This causes problems because
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence serial numbers are used to indicate that a zone has been
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence updated. If the serial number on the slave server is
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence lower than the serial number on the master, the slave
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence server will attempt to update its copy of the zone.
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence Setting the serial number to a lower number on the master
f8a95eb9127a97e81ad4f1295a9d1abce993ef63David Lawrence server than the slave server means that the slave will not perform
f8a95eb9127a97e81ad4f1295a9d1abce993ef63David Lawrence updates to its copy of the zone.
f8a95eb9127a97e81ad4f1295a9d1abce993ef63David Lawrence The solution to this is to add 2147483647 (2^31-1) to the
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence number, reload the zone and make sure all slaves have updated to
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence the new zone serial number, then reset the number to what you want
487e6abc16c1b2958d371b0d4e808953646b520aDavid Lawrence it to be, and reload the zone again.
