If the transfers are more costly than ftp-master doing some checkums, you can also check if zones are changed without having a new serial number by attaching a md5 checkum to the zone. The checksum can be create with something like: ZONEMD5=`tar cf - $ZONEDIR | md5` You can validate checksums with a cron job and we can even bump the serial automaticly if the checksums don't match (provided there was a serial). > Is this a good idea?

I think the biggest win is having some synchronisation between someone doing an upload and the "system" doing the mirroring. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
