Hello All,
I'm trying to use DBUS signal "PropertiesChanged" of
org.freedesktop.network1 /org/freedesktop/network1 *to detect network
interface is up or down OR the speed of the interface is changed.*
Is it possible? using a subscription to "PropertiesChanged" signal via the
below interface or PATH ?
If yes, how to test those, Currently I don't see any anything on my
dbus-monitor.
Here is how I am testing :
*# dbus-monitor --system "type='signal',path='/org/freede*
*sktop/network1'"#ifconfig wlan0 down*
# busctl introspect org.freedesktop.network1 /org/freedesktop/network1
