NSD 4.0.1

An Open Source and complete, high performance implementation of an authoritative DNS name server
NSD (Name Server Daemon) is an open source command-line software that implements an authoritative only, complete, simple and high performance DNS (Domain Name System) server on Linux-based operating systems.

NSD is a modern, fast and RFC compliant name server that is very well tested at the NLnet Labs and a regression tests report has been made available on the project’s homepage. When comparing NSD with BIND, it was discovered that there are no interoperability issues for the two resolvers.

More documentation, as well as a memory consumption test are available at http://www.nlnetlabs.nl/projects/nsd/documentation.html

What's New in version 4.0.0
  • documented in doc/NSD-4-features. Change configuration without restart, direct nameserver control with nsd-control, support a higher number of zones. Higher performance (compared to NSD3).
  • nsdc is gone. Use kill -HUP for reload (also checks if zonefiles have changed and rereads them), and kill -TERM for quit. Or use nsd-control for detailed control.
  • cron job for nsdcpatch is gone. nsd-control write creates zonefiles.
  • nsd.db has a new format that compacts itself when it is changed, thus nsdc patch is no longer necessary.
