Just for reference (or "fun"), I did a very quick and dirty port of the Python client to Perl ... for all of the Perl fans out there. That code is horrible, as I've not done any Perl coding for almost 9 years (it seems I've recovered after all those years ;-)). But once you've installed the Net::DBus package it should work. It is located in the same git repository as the python code. - -- kind regards, David Sommerseth OpenVPN Technologies, Inc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBAgAGBQJX0GMDAAoJEIbPlEyWcf3yjX4P/jtFYvK1VIThayYcs9rtYMQc gLv7G/PgfltiWrSRItmDu6xahJGte8akghDni1VClmY9d6r5lsYtId6QnlqoijlR o+Z6W7b1IenB0LRj2q2w3gJcc7XL+2rDkwSOu7Nqw+dFSmDdrA85TFCk55l6gucX elvhP4svn5/BTUXWu1PvceVrGiqA74XwE4HB+C+4xL7/j4TeybBxrXR5MWJSAteC 9njH6yqzU2r89c0biRYwVLDiO1XBBDIGM6osYwupO24PDeG82Vbtjb/GI4bF+dIo t0DfcuPpKqZYlkiDFQeDcfmt+3H1XEmhkDzeV3UmMhK5TvY8oZVq9ZMHJLFUTbDY M0qnJf7wVykebBctoLujaEl6IhclQKinq4ywQ7LnVXDwQrIubF07VowoOH4qDGY7 MPfn5Oq0qb+dL1bfB4lJbuK5A20ezQAslh5UqjhktDej9RXQu0F8C1N1H0psJRjE +JPgtxTsQvh0RmzhJtQv30dqcO8XFgDLK5tJ3GPJTuM1+nh76OYYjnewonr+AfQI pSx4UsG1B2RI7BGVcgr/1dfmkaxc4fvAVaBdtlXddnD2RgCPYjN6iBnPojQ56JNp zzLAtGPCPrr4Gb6L5Ulg1xZPPvhMZLaFx/SeKFETj/3Vf1llNqiMSCARJ30966tW DHetuWrI08j0Pi8JG7r9 =llV3 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ _______________________________________________ Openvpn-devel mailing list Openvpn-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-devel
