Convert Existing Named to NSD
NSD is an open-sourced server program for the Domain Name System (DNS). cPanel version 11.24 included NSD integration. NSD is a lightweight, fast alternative to BIND. It may be ideal for low-memory VPSes.
Take a look at the official cPanel NSD Integration notes: http://docs.cpanel.net/twiki/pub/AllDocumentation/ReleaseNotes/nsd-3.1.pdf.
Note: NSD is an authoritative-only Nameserver. BIND also includes caching/resolution services. You should be sure that the file /etc/resolv.conf does not contain 127.0.0.1 or your server IP addresses before proceeding with this. If it does, please contact Tech Support to have that updated on your VPS system (most VPSes will be configured to use an Greenix360 caching server and OpenDNS in /etc/resolv.conf).
