I'm going away for a week and want to make sure my ppp stays running as I
have RC5/DES stuff running on a few boxes and this FBSD machine is the
gateway for them.
I'm using an older version of PPP and every once in a blue moon it dies.
(upgrade, I know but dont have the time at the moment)
So I want a small script to run oh say every fe hours or something and
check to see if ppp is up. If not run it.
I wrote this little thing:
#!/bin/sh
ps ax | grep -v grep | grep -q city
if ( test $? -eq 0 )
then
echo "found"
else
echo "not found"
echo "running ppp..."
ppp -auto -alias city
fi
It works as far as I can tell. While testing it I was grepping for the
word ppp and even if ppp was not running it would return "found". But as
soon as I grepped for city instead it works and runs ppp fine.
I use bash and the above if-then-else was from a book on shell
programming. Is this a "right" way to do this?
thanks,
Keith
