fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User The best solution to solving installation and
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt configuration issues is to take preventative measures by setting
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User up logging files beforehand. The log files provide a
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt source of hints and information that can be used to figure out
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt what went wrong and how to fix the problem.

fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User Zone serial numbers are just numbers — they aren't
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt date related. A lot of people set them to a number that
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt represents a date, usually of the form YYYYMMDDRR.
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt Occasionally they will make a mistake and set them to a
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt "date in the future" then try to correct them by setting
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User them to the "current date". This causes problems because
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt serial numbers are used to indicate that a zone has been
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt updated. If the serial number on the slave server is
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt lower than the serial number on the master, the slave
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User server will attempt to update its copy of the zone.
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt Setting the serial number to a lower number on the master
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt server than the slave server means that the slave will not perform
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt updates to its copy of the zone.
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt The solution to this is to add 2147483647 (2^31-1) to the
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt number, reload the zone and make sure all slaves have updated to
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt the new zone serial number, then reset the number to what you want
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt it to be, and reload the zone again.
