f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering The best solution to solving installation and
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering configuration issues is to take preventative measures by setting
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering up logging files beforehand. The log files provide a
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering source of hints and information that can be used to figure out
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering what went wrong and how to fix the problem.

f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering Zone serial numbers are just numbers-they aren't date
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering related. A lot of people set them to a number that represents a
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering date, usually of the form YYYYMMDDRR. A number of people have been
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering testing these numbers for Y2K compliance and have set the number
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering to the year 2000 to see if it will work. They then try to restore
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering the old serial number. This will cause problems because serial
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering numbers are used to indicate that a zone has been updated. If the
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering serial number on the slave server is lower than the serial number
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering on the master, the slave server will attempt to update its copy of
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering Setting the serial number to a lower number on the master
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering server than the slave server means that the slave will not perform
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering updates to its copy of the zone.
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering The solution to this is to add 2147483647 (2^31-1) to the
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering number, reload the zone and make sure all slaves have updated to
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering the new zone serial number, then reset the number to what you want
f9e00a9f5870a9bcae2de8bf1cb3ce04703112e1Lennart Poettering it to be, and reload the zone again.
