ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering The best solution to solving installation and
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering configuration issues is to take preventative measures by setting
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering up logging files beforehand. The log files provide a
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering source of hints and information that can be used to figure out
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering what went wrong and how to fix the problem.

ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering Zone serial numbers are just numbers-they aren't date
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering related. A lot of people set them to a number that represents a
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering date, usually of the form YYYYMMDDRR. A number of people have been
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering testing these numbers for Y2K compliance and have set the number
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering to the year 2000 to see if it will work. They then try to restore
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering the old serial number. This will cause problems because serial
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering numbers are used to indicate that a zone has been updated. If the
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering serial number on the slave server is lower than the serial number
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering on the master, the slave server will attempt to update its copy of
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering Setting the serial number to a lower number on the master
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering server than the slave server means that the slave will not perform
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering updates to its copy of the zone.
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering The solution to this is to add 2147483647 (2^31-1) to the
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering number, reload the zone and make sure all slaves have updated to
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering the new zone serial number, then reset the number to what you want
ea5943d3862cc690daa76e2ad336737407ec711cLennart Poettering it to be, and reload the zone again.
