a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync The best solution to solving installation and
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync configuration issues is to take preventative measures by setting
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync up logging files beforehand. The log files provide a
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync source of hints and information that can be used to figure out
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync what went wrong and how to fix the problem.

a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync Zone serial numbers are just numbers — they aren't
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync date related. A lot of people set them to a number that
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync represents a date, usually of the form YYYYMMDDRR.
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync Occasionally they will make a mistake and set them to a
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync "date in the future" then try to correct them by setting
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync them to the "current date". This causes problems because
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync serial numbers are used to indicate that a zone has been
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync updated. If the serial number on the slave server is
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync lower than the serial number on the master, the slave
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync server will attempt to update its copy of the zone.
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync Setting the serial number to a lower number on the master
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync server than the slave server means that the slave will not perform
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync updates to its copy of the zone.
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync The solution to this is to add 2147483647 (2^31-1) to the
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync number, reload the zone and make sure all slaves have updated to
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync the new zone serial number, then reset the number to what you want
a33af978add1a03aab11b2895f441af5cb2a11a6vboxsync it to be, and reload the zone again.
