How to execute a script once an interface is up or down?

[boolean]

puppy have an unusual interface management , so the internet is not helping

any idea?

Your questions is worded a little strange. Can you elaborate a little? Puppy has a terminal in which you can execute scripts. In addition, you can create scripts and save them in root/my-applications/bin. You also have to set the script as executable.

So long as DHCP's running, it's "ifconfig eth0 up" for me. Down drops it. If you meant wireless, look @ these examples.

EDIT: i meant after i bring an interface up , like : ifconfig eth0 up, i would like for a script(specific to that NIC) to be automatically executed ;

like this question here:

It's OK, the next person can ask.

I use this loop at the beginning of a keep alive/NFS scan script...it basically polls the network until the internet appears... it might be adaptable for your use..you could probably drop the SUBNET bit and just check for ANY output

Code: Select all

while [ "$SUBNET" = "" ]; do
	SUBNET=$(ifconfig | grep inet | grep -v 127.0.0.1 | awk '{print $2}' | cut -d ':' -f 2)
	sleep 20
done
