[...snip...] Time for some proof-of-concept code! <https://gitlab.com/dazo/openvpn-dbus-poc/tree/master> This is just a plain and silly TCP management to D-Bus proxy. It does nothing fancy, but it is just a little introduction to how D-Bus can simplify getting an integration to a management interface in OpenVPN. To do the more advanced features, such as signalling ("push" messages from server to listening D-Bus clients) is something which will require a lot more work and I have not considered doing this. All information to get started should be fairly well documented in the source code. But if anyone have any questions, no question is too silly . A few details. - - *DO NOT RUN THIS IN PRODUCTION!* This is *Proof of Concept* code. It will be buggy, it is hacky and you cannot fully trust it. - - A proper implementation will not use Python on the D-Bus server side, but will be included into the core OpenVPN C code. - - A proper implementation will also use "properties". This is currently not possible to do via the dbus-python implementation, at least not without too much additional hackery. For a PoC, I did not consider this important. But a proper implementation in C will make use of object properties to provide read-only information. - - The API provided via the D-Bus by this proxy WILL change. - - Please do not start massive improvements to this code, unless it helps understanding better D-Bus features which can be worth investigating further. Again: A proper D-Bus server implementation will happen inside the OpenVPN C code. This code is purely to help us getting further in this discussion. - - And please do not judge the code harshly. I have prioritised getting something which works for a PoC. I have not added much styling or very describing comments. And yes, there will be bugs. - -- kind regards, David Sommerseth OpenVPN Technologies, Inc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBAgAGBQJX0E5MAAoJEIbPlEyWcf3yh4wP/i5hEjqzqHy6hnocA0ANT5ov VGfG1ZUF4QMUsyhjEbN2D1OM5sPQaPmH20CRcwbZGaZnuavDtjwBjc82IeopGaYC S4VmjQYNwGMawmrYTOH3/ITg/JzySQ60wKMv5AZBPK31zcqoFFKaYw8klsvTsj/N sO+ew/btlNdeosMKBGX/4+VjadgsvudX/o7GYfHVRonZX9E3B7tV7gE4EX5Z99xn UEnnwHzH6Olw6dhObNopPaFiFLte9Indt1iOLb3Fng0qZL5BDqw/ltr4h5klmD3R gJGFi75yarT41wW65ONZPm/530gzuwWEyaS2yPJ8YF7QLSiy8RZcMhdxjUP4a+dA 31dBfv/pWXHwM5lan668d9aIjAJ/q++9IMZmwIaqNI7MCudwemXjZ1opnwopz5rQ nDjtOCjMeUhYo7aJAPTcxfUF+ty4JnMSnkWMRt7PJg1hJG5E4VbRiWPPDIfsXW0h g8WRMPHPe/bG3dC/qH6zdzupi7GqHy9UyPeVBFrJ56TuWoGeuRKQ6NL4ahn67Vt1 th5rifBMEqsq/wxeQ+7EBYlgkNrO7A9ewo/5KNQVnYeRUv+kWAwrxeUAYzMWh7B8 Co0UX0mKV65IR/QH0hwag0mRgS7IxTX9Y5pV7WTfqmIzxaggWTrcJFVRby5Wr4Cq Na26b+buT6xGdEnotrqf =bbcG -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ _______________________________________________ Openvpn-devel mailing list Openvpn-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-devel
