You can set in the config file a size-limit for each logfile, and BIND
will automatically rotate it. You can also specify how many versions
it is to keep.
If you want to specifi a log-file rotation immediately (eg
exactly at midnight etc), you can do this:
# mv log.3 log.4
# mv log.2 log.3
# mv log.1 log.2
# mv log.0 log.1
# mv log log.0
# ndc reload
As the logfile does not longer exist under the name, a reload will create
a new logfile.
I did ask (as part of our Bronze support contract) to provide a faciliy to
*only* closes/reopenes logfiles without the added overhead of a reload to
facilitate this a bit better. Hopefully it will make it into BIND-9.
It gets more complicated if you GZIP (or otherwise compress) the logfiles,
so they no longer conform to the naming scheme BIND expects....
