If you know of any other distribution with a ODNS package, be nice to tell me.
Latest stable release
The latest release is odns version 0.3, which you can download here: http://download.tuxfamily.org/odns/odns-0.3.tar.gz (or by ftp, anonymously).
Older stable releases
You can get the development version from the source code’s SVN repository.
It is browsable from the web at:
You can also check-out anonymously with SVN:
svn co svn://svn.tuxfamily.org/svnroot/odns/odns/trunk
If you want to help with development, feel free to drop me an email, send me patches, bug reports, etc. Obviously I will not give write access to SVN immediately, but only after several relevant patches, so don’t ask right away.
