1f5eafd61b4c4271dbcf9d9106a722148e51d5ebDavid Lawrence The best solution to solving installation and
1f5eafd61b4c4271dbcf9d9106a722148e51d5ebDavid Lawrence configuration issues is to take preventative measures by setting
1f5eafd61b4c4271dbcf9d9106a722148e51d5ebDavid Lawrence up logging files beforehand. The log files provide a
1f5eafd61b4c4271dbcf9d9106a722148e51d5ebDavid Lawrence source of hints and information that can be used to figure out
1f5eafd61b4c4271dbcf9d9106a722148e51d5ebDavid Lawrence what went wrong and how to fix the problem.

44215b932d4f0ce5257d794cb6f76b9282455eb1Mark Andrews Zone serial numbers are just numbers — they aren't
44215b932d4f0ce5257d794cb6f76b9282455eb1Mark Andrews date related. A lot of people set them to a number that
19e0a2c2d13500712564c59c5feb76f7f4209383Brian Wellington represents a date, usually of the form YYYYMMDDRR.
fcf28b759c65388e8875f2dbcf8eb5fa786b29ecAndreas Gustafsson Occasionally they will make a mistake and set them to a
ee303f481dfefcd4e4994f8b8b17f2de32aa4d69Brian Wellington "date in the future" then try to correct them by setting
7357590beef5f671cfdd4ec4304e5210adfb0d8aBrian Wellington them to the "current date". This causes problems because
a13ca8a12516081b93edd9cbf6f07b7e0fcb02cfBrian Wellington serial numbers are used to indicate that a zone has been
19872fdfb75357354a83b74932f661d4b0b6e4ddAndreas Gustafsson updated. If the serial number on the slave server is
1255d388f034dc556d235a002527101781dbeb29Mark Andrews lower than the serial number on the master, the slave
242bba8991b030b7764f0bdca3922d75c34ea51eAndreas Gustafsson server will attempt to update its copy of the zone.
19872fdfb75357354a83b74932f661d4b0b6e4ddAndreas Gustafsson Setting the serial number to a lower number on the master
f6f4d7ee0f04474a13f4c28f1d05112325f3c8b0David Lawrence server than the slave server means that the slave will not perform
cd5a526372c715217370f7639dc56e6d48600329David Lawrence updates to its copy of the zone.
fda0ab6a96a7edb1acbde0c77ead0542979b0f24Bob Halley The solution to this is to add 2147483647 (2^31-1) to the
0c33e418cb443ade8ed55f5433bc4d409c7af0b8David Lawrence number, reload the zone and make sure all slaves have updated to
0c33e418cb443ade8ed55f5433bc4d409c7af0b8David Lawrence the new zone serial number, then reset the number to what you want
87cafc5e70f79f2586d067fbdd64f61bbab069d2David Lawrence it to be, and reload the zone again.
