Named

Manually updating a Dynamic controlled zone

"If you have to edit the zone files of dynamic zones manually while the DNS server is running, you'll have to freeze the zones with # rndc freeze <myzone> before editing and unfreeze them with # rndc thaw <myzone> after editing. This is because named(8) has internal state information and external journal files attached to dynamic zones that have to be kept in sync with the zone files".

Rsync

To delete files in the target if they disappeared from the source, then add the --delete option to your command. For example:

rsync -avh source/ dest/ --delete
NB: -avh is for --archive --verbose --human-readable.

Migration of folders to a new server

One shot

rsync -av /var/db/ports/ root@newice3:/var/db/ports/

rsync -av /etc/ root@newice3:/etc/oldice3/

rsync -av /usr/local/etc/ root@newice3:/usr/local/etc/oldice3/

rsync -av /etc/ssh/ssh_config /etc/ssh/sshd_config newice3:/etc/ssh/

rsync -av /etc/banner /etc/motd.template /etc/pki/ newice3:/etc/

rsync -av /etc/pki/ newice3:/etc/pki/

1 full + diff at the migration time

rsync -av --exclude={'rc.d','oldice3'} /usr/local/etc/ root@newice3:/usr/local/etc/ --delete --dry-run

rsync -av /root/ root@newice3:/root/ --delete --dry-run

rsync -av /home/ root@newice3:/home/ --delete --dry-run

rsync -av /var/www/ root@newice3:/var/www/ --delete --dry-run

rsync -av /usr/local/www/ root@newice3:/usr/local/www/ --delete --dry-run

rsync -av /var/log/ root@newice3:/var/log/oldice3/ --delete --dry-run

rsync -av /var/awstats/ root@newice3:/var/awstats/ --delete --dry-run

rsync -av /var/log/www/ root@newice3:/var/log/www/ --delete --dry-run

rsync -av /var/db/mysql/ root@newice3:/var/db/mysql/ --delete --dry-run (to do when mysql server is off)
