DHCPv6: Dibbler - a portable DHCPv6

Dibbler is a portable DHCPv6 implementation. It supports stateful (i.e. IPv6 address granting and IPv6 prefix delegation) as well as stateless (i.e. option granting) autoconfiguration for IPv6. Currently Linux 2.4 or later and Windows XP or later are supported. It features easy to use install packages (Clickable Windows installer and RPM and DEB packages for Linux) and extensive documentation (both for users as well as developers). Dibbler is developed under GNU GPL licence. It means that it is free for all, including commercial usage.

This project was started in 2003 as master thesis by Tomasz Mrugalski and Marek Senderski of Computer Science faculty on Gdansk University of Technology. This project is named Dibbler (after famous CMOT Dibbler from fantastic Discworld series by Terry Pratchett). If you are interested in porting it to other systems/architectures, contact Tomasz Mrugalski for info and guidelines.

Please do not contact author directly and instead use mailing lists for discussion or bugzilla for bug reports. Contact author directly only if discussing security issues or other confidential matters.

Supported architectures and systems:

Experimental support means that this architecture lacks confirmation by users that everything is fully functional or there are known deficiencies.

If you have successfuly run Dibbler on onther architectures or systems, let me know so I can update this list. If you would like to have Dibbler running on some other architecture not mentioned above, and you are ready to provide me access to such hardware, let me know.

News

2015-08-09: Dibbler 1.0.1 has been released. It contains a number of bug fixes that were already released in the 1.0.1 Release Candidate 1 and several new fixes. One of them may have security implications, so upgrade is strongly encouraged.

2014-07-13: The second Release Candidate for Dibbler 1.0.0 has been released. Due to other obligations, 1.0.0RC1 was available for a very long time and I never had a chance to release 1.0.0 final. In the mean time, quite a few of fixes and small features were added (Changelog mentions 35 items, but I'm sure some of them were not listed). So formally this is a second RC, but it contains unexpectedly large changes for an RC. Keep that in mind. This time I expect the delay between RC and final to be much shorter (couple weeks). Couple changes worth mentioning:

See CHANGELOG for a complete list of changes. If you find bugs, please report them on Dibbler bugzilla. If you need help or want to share your thoughts, take a look at one of two mailing lists: dibbler or dibbler-devel. Please do not contact author directly, unless you want to report security issues or discuss confidential matters.

2013-07-30: Dibbler 1.0.0 Release Candidate 1 has been released! This version is being released today to celebrate 10th anniversary of the DHCPv6 protocol. The RFC3315 that defines it was published exactly 10 years ago - on 30th July of 2003. According to the author's knowledge, Dibbler is currently the only implementation that implements every feature mentioned in the RFC3315. Please note that feature complete does not mean bug free ;-) This release brings in all outstanding RFC3315 features that used to be missing in previous releases. In particular:

Enjoy!

2013-06-27: Dibbler 0.8.4 has been released. There is no single major new feature, just a lot of bug fixes: 34 bug fixes, tweaks and small improvements since 0.8.3. Vendor class and User class methods are now implemented. Relay support has been rewritten. It is now possible to select subnet based on interface-id or value of linkaddr field set by the relay. Client classification has been improved and now can be used to differentiate between 2 or more classes, e.g. docsis3.0 and eRouter in cable networks. Confirm support has been cleaned. Daemon mode no longer has issues when reading from socket descriptor 0. The database format has changed a bit. It now stores interface names, not just interface indexes. That is helpful in cases your interfaces has changed, e.g. when your ppp0 interface went down and was recreated with different ifindex. Opening up old database should be seamless, but make sure you make a backup before migrating to 0.8.4. Dibbler server no longer does by default destination address filtering against the addresses sockets are bound to. If that bothers you, because on your OS you see the same incoming packet being received over two sockets, please use --enable-dst-addr-check in configure phase.

2013-04-27: Dibbler 0.8.4 Release Candidate 1 has been released. There is no single major new feature, just a lot of bug fixes. In particular, relay support has been rewritten. It is now possible to select subnet based on interface-id or value of linkaddr field set by the relay. Client classification has been improved and now can be used to differentiate between 2 or more classes, e.g. docsis3.0 and eRouter in cable networks. Confirm support has been cleaned. Daemon mode no longer has issues when reading from socket descriptor 0. See CHANGELOG for a complete list of changes.

2013-01-20: Dibbler 0.8.3 has been released. The biggest feature is a rewritten address and prefix allocation engine. Both follow the same algorithm now. It is possible to reserve specific address and/or prefix for a given host. The host can be referenced by DUID, remote-id or link-local address. Both in-pool and out-of-pool reservations are now supported. Support for DDNS is now significantly improved. Secure DNS Updates using TSIG are now supported. Many, many bugs were fixed and the FQDN handling code is now much more robust. The code now compiles on Solaris 11. It is not yet fully usable, and there are outstanding problems with link-layer address detection, but it is better than nothing. Script execution is now improved as well. It is called when receiving stateless configuration (after receiving reply to INF-REQUEST) and extra options (like FQDN and vendor-specific info) are now properly passed. See CHANGELOG for a complete list of changes.

2011-11-13: Dibbler 0.8.1 Release Candidate 1 is released. This release introduces number of useful additions, new features and the usual bug fixes. In particular, the highlights of this release are:

2011-09-05: Dibbler source has been moved to GIT repository at github.

2011-05-11:Dibbler 0.8.0 has been released. That is a new release after long time. Dibbler development just resumed.

2011-03-14: I got my first mac! Yay! After figuring out how to do anything useful without insert, delete, pgup and pgdown, I think I was able to fix many problem with Mac OS port. I'm able to run both client and server on my mac. If you have Mac hardware available, please Get the latest code from SVN and give it a try.

2011-02-11: I'm happy to announce that my 7 year struggle to complete my Ph.D. is finally over. It appears that I will finally have some time to reinvigorate Dibbler. There are many things happening lately in DHCP world, so it seems I'll be busy in the near future. In the mean time, Dibbler became quite outdated. Please send a note to the mailing list regarding missing features that you find the most urgent to develop.Cheers, Tomasz Mrugalski, Ph.D.

2010-09-17: Good news, everyone! After a year and a half, I finally found some time to wrap everything that was slowly going around, packed and released 0.8.0 Release Candidate 1. The major changes include support for Windows 7 and Mac OS (both experimental), support for CONFIRM, client and server will reload their databases during boot, Linux console now can be colorful, support for bunch of experimental stuff added. Finally, there's large code refactoring taking place, so let's hope that everything is working... Enjoy
