Hello,
We primarily update the DNS records by nsupdate from a web interface.
Under this case, if I modified the zone file directly by hand, will
nsupdate overwrite the modification?
If you attempt to update a dynamic zone by hand, without first freezing
the zone or shutting down named, you will likely corrupt the zone. You need
to use 'rndc freeze zone' and then do the update by hand (don't forget to
bump the serial number!), and then do 'rndc thaw zone' (assuming you're
using a recent version of BIND). While the zone is frozen, updates made
dynamically (e.g. via your web interface) will be discarded. For these
reasons, it's often good to think about whether the hand-editing is really
necessary and what impact it has on your overall process.
