One problem, the script runs forever. Can you please edit it so it only runs for say 10secs constantly when it is executed.

Which one are you running?

Post the output of the script...

And post your actual script.

What does "/usr/sbin/ping ip-address" do, does it just say "host is alive" or does it run forever?

Right, i think the modem was just rejecting the ping if i pinged it constantly like the script was doing.

if i type ping 192.168.100.1 into terminal i get a host is alive.

Im running the second script you gave to me


I think i have it working now, setup with the cronjob and everything. Could i just ask how long this script is set to run for? because if it runs constantly forever my modem will start to reject the pings. I have told cron to run the script every min. But what i would like it to do is run for 10 secs only each time.

if i ping thru usr/sbin/ping 192.168.100.1 i get one responce.

It should be just pinging it three times in the "for" loop, not continually.

Now if i unplug the modem the script doesnt seem to run, or do anything.

The script doesnt seem to work unless i run it manually, can you please tell me what to put in the cronjob file to make the script run every min.

1. You normally have to fully path the script in the crontab file.

2. you may need to fully path the shutdown program in the script as well.
