if [ -x /sbin/ifup-local ]; then
/sbin/ifup-local ${DEVICE}
In the code snippet above, if ifup-local script exists in /sbin location, then script gets executed with an interface name in argument. Usually no such ecript like ifup-local exists so in order to run a startup script automatically after a network interface is up. Create an executable script called ifup-local in /sbin and put in there any command or script you wish to run.
Here is an example:
if [[ "$1" == "eth0" ]] then echo "this part will be executed right after eth0 is up." echo "so you can put any startup command for eth0 here" else #DO_NOTHING fi
when script is done, use command to get the script executable.
$ sudo chmod +x /sbin/ifup-local
