What is opt_dyndns?

opt_dyndns is an OPT package for the Fli4L project. It allows to automatically update the dynamic hostname entry at providers for dynamic DNS services when the router connects to the Internet.

Development of this package was sponsored by
headwork Consulting GmbH

Note: I am tired that some people, to whom I gave my software for free, are bitching about that it contains bugs, that I take too much time for providing updates or bugfixes or that I don't answer support requests or answer them arrogantly. Therefore I will, effective immediately, stop any support and further development. The packages will still be available for download as they currently exist, but I will no longer answer any emails, accept bug reports or even fix any bugs. There will be no adaptations to new versions of FlI4L unless I need them for myself, and in that latter case there will no updated documentation, if I make the updates available at all.

opt_dyndns has been taken over by somebody else who apparently has removed the Windows configuration program from the package without mentioning this in the instructions. He has also forgotten to remove my E-Mail address from the instructions. :-( You can download any of the archives below if you are interested in the config program, but I can not guarantee that it will work with the modified package.
