Bind updating serial number for zones christina dating
It's so that other servers doing zone transfers can verify if they need to do a zone transfer. Most Zone files are just text files in the *nix world.Normal convention is that the Serial number is the timestamp in date ISO date format followed by a two number increment 2014101501 Microsoft products are set up to autoincrement the Serial Number when changes are made.
For, the specific problem at hand, I think the larger challenge would be to identify the number that would make all zones think is a larger one and synchronize them all to that.
Then simply add add, and then remove a temporary record in each zone with nsupdate. is the tool of choice for ignoring serial numbers and just doing it.
This approach should not be used for day to day work (it throws off serial number accuracy), but sometimes the need for working out of band is greater.
The term 'masters' here doesn't mean that the servers listed have to have the zone configured as 'master' - it just means that these servers so listed are authoritative for the zone and can provide a zone update if one is requested of them.
Slave servers can provide zone updates to other slaves.
