That's why I believe it's better to use zone transfers because it's automatic. You don't have to _restart_ BIND, you have to _reload_ it. Otherwise BIND can't know that the zone file on disk has changed. You'd do something like: rsync source:/some/zone dest:/bind/dir/zone ssh dest 'rndc reload zone' -- Anand ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

RE: bind replication
A further complication on this is if you are using dynamic updates. If you are using dynamic zones, bind will create journal files. If you were to copy over the zone files and journal files and do a reload, bind determines whether or not to reload the zone based on the timestamp of the zone file. It does not look at the time on the journal file. If you wished to sync zone files in this manner, with dynamic zones, you would need to freeze the zones on the sending side, which forces a write of the data that is in the journal file to the zone file, freeze the zones on the receiving side then copy the files over reload unfreeze zones on both sides. ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
