Hi *, since NetworkManager 1.22 using the signal /org/freedesktop/NetworkManager/ Settings/PropertiesChanged is deprecated. One should use /org/freedesktop/ DBus/PropertiesChanged instead. Since NetworkManager 1.32 this signal indeed is completely removed. I couldn't find any example on how to easily replace the code using the deprecated signal. I use PropertiesChanged to listen for connectivity changes, escpecially activation/deactivation of interfaces. I want to configure a few things, whenever connections were (de)activated. I use the perl module Net::DBus for this job. Any idea? Thx and bye. Michael.
