PowerDNS 2.9.4 released [LWN.net]

Version 2.9.4 of PowerDNS, a name server alternative to the poplular Berkeley Internet Name Domain (BIND named) server, has been released. "Big news is the addition of a recursing nameserver which has sprung into existence over the past week. It is in use on several computers already but it is not ready for prime time. Complete integration with PowerDNS is expected around 2.9.5, for now the recursor is a separate program."

The recursor is claimed to offer a fairly big performance improvement over BIND 9, but a few bugs are still being worked out.

According to the online manual: "PDNS is an authoritative only nameserver. It will answer questions about domains it knows about, but will not go out on the net to resolve queries about other domains. However, it can use a recursing backend to provide that functionality. When PDNS answers a question, it comes out of the database, and can be trusted as being authoritative. There is no way to pollute the cache or to confuse the daemon. PDNS has been designed to serve both the needs of small installations by being easy to setup, as well as for serving very large query volumes on large numbers of domains."

Other new features in this release include:

All SQL queries are available for configuration.
Zone replacement transfers are only done with capable remote servers.
Error messages were improved.
A slowdown bug with pdns_control was fixed.
Updates are rolled back if a remote server goes down during an AXFR.
Lots of bugs have been fixed.
Documentation has been updated.
