Script to monitor interface

equinox · 12-03-2005, 12:50 AM

Hi guys i need some help...

Sometimes my adsl script dies and so I need a script that will perhaps run under cron that chick the status of ppp0 and if it's down it will do a "service adsl restart".

The other problem is that sometmies it also gets confused when coming up and ppp0 becomes ppp1 and I need to keep it at ppp0.

Anyone know how to write such such a script that can monitor and fix whats happening? Its not for me but for a client I have and I've tried searching on the net for such a script but can't seem ti find anything.

You could run a daemon which checks whether any site is accessed with e.g.:

Code:

while (true) ; doping -c1 www.linuxquestions.org >/dev/null 2>&1
sleep 1
done

If ping returns FALSE (non-zero) you could restart your interface.
