In your original mail you only said "monitor connectivity" so anything is just guesswork. >> If you want to monitor overall connectivity, you need to monitor main >> /o/f/NM object. > > This is, what I did before NetworkManager's PropertiesChanged signal got > deprecated. > My problem is to understand, what path and what interface I have to use in > this part of my code, after the PropertiesChanged signal moved from > NetworkManager to DBus: > > my $busobjpath = "org.freedesktop.NetworkManager"; > my $busif = "org.freedesktop.DBus.Properties"; > my $oBUSIF = $oBUSSVC->get_object( $busobjpath, $busif ) || die $!; > $oBUSIF->connect_to_signal( > "PropertiesChanged", sub { > &{ \&onPropertiesChanged }( @_ ) > } || die $!; > } > I do not see any reference to object here so I have no idea what this code does. The following certainly works def properties_changed(interface_name, changed_properties, invalidated_properties): print (interface_name, changed_properties, invalidated_properties) bus = dbus.SystemBus() obj = bus.get_object("org.freedesktop.NetworkManager", "/org/freedesktop/NetworkManager") iface = dbus.Interface(obj, "org.freedesktop.DBus.Properties") iface.connect_to_signal("PropertiesChanged", properties_changed) > The original code now tells me > > no signal PropertiesChanged in interface org.freedesktop.NetworkManager at / > usr/lib/perl5/vendor_perl/5.32.1/x86_64-linux-thread-multi/Net/DBus/Binding/ > Introspector.pm line 420. > > which seemed clear to me, because it got deprecated. > > > Thx and bye. > Michael. > > > _______________________________________________ > networkmanager-list mailing list > networkmanager-list@gnome.org > https://mail.gnome.org/mailman/listinfo/networkmanager-list > _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
