Hi, I am not familiar with this Perl's Net::DBus, but in general: On D-Bus, you have the well-known name ("org.freedesktop.NetworkManager") where you find NetworkManager's D- Bus API. There, you find many D-Bus objects, at paths that start with "/org/freedesktop/NetworkManager". You see them with `busctl tree org.freedesktop.NetworkManager`. All of these objects also implement the standard D-Bus interface "org.freedesktop.DBus.Properties" -- as documented at https://dbus.freedesktop.org/doc/dbus-specification.html That interface, has (among) others a signal "PropertiesChanged". This "org.freedesktop.DBus.Properties.PropertiesChanged" signal works very similar to the earlier "PropertiesChanged" signals from the NM specific interfaces ( "org.freedesktop.NetworkManager*"). So, yes, there should be not much to do except replace the interface name "org.freedesktop.NetworkManager*" with "org.freedesktop.DBus.Properties". you mention specifically my $busobjpath = "/org/freedesktop/NetworkManager/Settings"; In `d-feet` you'll see that this object only has three properties. So you'll see few PropertiesChanged signals on that object... Does that help? Otherwise, please share a working, minimal example. best, Thomas _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
