1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson The best solution to solving installation and
37f9a536593b696e5a3dcec443e1475f22fb5afdjvergara configuration issues is to take preventative measures by setting
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson up logging files beforehand. The log files provide a
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson source of hints and information that can be used to figure out
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson what went wrong and how to fix the problem.

1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson Zone serial numbers are just numbers — they aren't
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson date related. A lot of people set them to a number that
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson represents a date, usually of the form YYYYMMDDRR.
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson Occasionally they will make a mistake and set them to a
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson "date in the future" then try to correct them by setting
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson them to the "current date". This causes problems because
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson serial numbers are used to indicate that a zone has been
37f9a536593b696e5a3dcec443e1475f22fb5afdjvergara updated. If the serial number on the slave server is
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson lower than the serial number on the master, the slave
1fb669628faa2eb90d370eb249980b3a1807babaneil_a_wilson server will attempt to update its copy of the zone.
b26e36d8a08a1c775531659c04abc3d4ed504139jvergara Setting the serial number to a lower number on the master
b26e36d8a08a1c775531659c04abc3d4ed504139jvergara server than the slave server means that the slave will not perform
37f9a536593b696e5a3dcec443e1475f22fb5afdjvergara updates to its copy of the zone.
b26e36d8a08a1c775531659c04abc3d4ed504139jvergara The solution to this is to add 2147483647 (2^31-1) to the
b26e36d8a08a1c775531659c04abc3d4ed504139jvergara number, reload the zone and make sure all slaves have updated to
37f9a536593b696e5a3dcec443e1475f22fb5afdjvergara the new zone serial number, then reset the number to what you want
da7ab15aee42edf1c4ff33f66ca717f019b4a578lutoff it to be, and reload the zone again.
