Hi, I wanted to know is it possible to write a rule for the udev which will run a program when the attribute of the device changes. For example if the ethernet plug is removed, the attribute "carriers" of net class will change from 1 to 0. To track this change i wrote the following rule in the /etc/udev/rules.d/70-persistent-net.rules file SUBSYSTEM=="net", DRIVERS=="?*", ATTR{carrier}=="0", ATTR{address}=="00:0c:29:27:a2:95", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", RUN+="/bin/up.sh" up.sh will echo some thing in to the text file in my home directory. But the up.sh is not getting executed. Thanks in advance.
