Welcome to the 0.9 release of Kea. Kea is a new DHCP implementation being developed by Internet Systems Consortium, Inc. that features fully functional DHCPv4, DHCPv6 and Dynamic DNS servers. Both DHCP servers fully support server discovery, address assignment, renewal, rebinding and release. The DHCPv6 server supports prefix delegation. Both servers support DNS Update mechanism, using a stand-alone DDNS daemon, which is part of the release. Kea 0.9 brings in notable changes. A prominent one is that support for FreeBSD, NetBSD and OpenBSD has been added. The code should also work on Mac OS X, but it was not fully tested. This release also removes the BIND10 framework and all DNS components that were not useful for DHCP operation. Kea is now a pure C++ solution without Python dependencies. keactrl, a shell script, has been added to control Kea daemons operation. The configuration process has changed as well. The configuration is now stored in JSON files that are loaded at start-up. Servers can be instructed (using POSIX signals) to reload their configuration without any restarts. Kea temporarily lost the capability to have its configuration updated remotely. There are plans to restore that capability in the upcoming releases. Note for migrating from Kea 0.8 to 0.9, the JSON-based configurations need to be updated. Support for OpenSSL has been added. During compilation time, Kea requires just one cryptographic library to be present: either Botan or OpenSSL. DDNS now supports cryptographic signatures (TSIG). HMAC-MD5, HMAC-SHA1, HMAC-SHA224, HMAC-SHA256, HMAC-SHA384 and HMAC-SHA512 can be used. DHCPINFORM (DHCPv4) and Confirm (DHCPv6) messages are now supported. This release also features a significantly revamped Kea Administrator Reference Manual and example configuration files. The number of examples is currently small, but there are plans to expand the collection in the near future.

In addition, all logging messages have unique documented explanations. This documentation is included with the installation or via http://kea.isc.org/docs/ in HTML, plain text, or PDF formats. We also maintain a public open source code tree and wiki pages with roadmap and issue tracking at http://kea.isc.org/. Limitations and known issues with this DHCP release can be found at http://kea.isc.org/wiki/KeaKnownIssues We'd like users of this software to please let us know how it worked for you and what operating system you tested on. Feel free to share your configuration or use case. Also we would like to hear whether the documentation is adequate and accurate (please open tickets for documentation omissions and errors). We want to hear from you even if everything worked. If you have any comments or questions about working with Kea, please share them to the Kea Users List https://lists.isc.org/mailman/listinfo/kea-users or to the Kea Jabber room. Bugs and feature requests may be submitted via the ticket tracking system at http://kea.isc.org/. The following summarizes the significant changes and important upgrade notes since the previous release (0.9-beta1). (See the git history for more details and additional development.) 832. [bug] jiri Compilation fix for PostgreSQL on i686. Thanks to Jiri Popelka from RedHat for providing a patch! (Trac #3532, git 96a06654f2177444dcea3a0e9f6fa06947855497) 831. [func] marcin DHCP servers check if the interfaces specified in the configuration, to be used to receive DHCP messages, are present in the system. If the interface doesn't exist, an error is reported. In addition, the SO_REUSEPORT flag is set for IPv6 sockets as multiple multicast sockets can be bound to the DHCPv6 server port.
