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. Regards, Shashank K S http://www.mindtree.com/email/disclaimer.html
