I am trying to run dbus commands remotely. On the remote machine I have edited system.conf to listen on port 55556. I can run connmand dbus commands remotely. I have edited list-modems to the following: bus=dbus.bus.BusConnection("tcp:host=10.42.243.96,port=55556") I get the following when I run the script: ERROR:dbus.proxies:Introspect error on :1.1:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 2 matched rules; type="method_call", sender=":1.7" (pid=0 comm="") interface="org.freedesktop.DBus.Introspectable" member="Introspect" error name="(unset)" requested_reply="0" destination=":1.1" (uid=0 pid=4352 comm="ofonod ") Traceback (most recent call last): File "./list-modems", line 11, in <module> modems = manager.GetModems() File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 70, in __call__ return self._proxy_method(*args, **keywords) File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 145, in __call__ **keywords) File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 651, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 2 matched rules; type="method_call", sender=":1.7" (pid=0 comm="") interface="org.ofono.Manager" member="GetModems" error name="(unset)" requested_reply="0" destination=":1.1" (uid=0 pid=4352 comm="ofonod ") Any suggestions as to what is happening?
