A collection of useful commands and helpful advice for both myself and aspiring admins.

Update DNS

Connect to Paphos cd /etc/bind/master Backup zone file db.Redbrick.dcu.ie Run rdnc freeze redbrick.dcu.ie (produces no output) Update serial number (line 4, format: YYYYMMDD(number of changes)) Add new domain under the $ORIGIN that you need (based on "tld") Run rndc thaw [domain] service bind9 status named-checkzone (zone file/db.Redbr...) check zone to make sure it follows syntax and is valid record var/log/named/(default.log) are logs of dns errors (pretty shit)
