What's the syntax for sending a dbus message to another machines dbus daemon using dbus-send? I see there's TCP/IP support for the destination address, but I can't find any docs on how to actually specify the address.
回答1:
Override the session bus address using the environment variable:
DBUS_SESSION_BUS_ADDRESS=tcp:host=server.example.org,port=77777 dbus-send ...
Note that the buses running by default do not listen on TCP. You have to run your own bus instance for that.
