I'm using a cron script every minute to ping outside my network. The
address I'm using is one given to me for this purpose by my new provider
(Activ/Powertel).
#!/bin/sh
# first ping occassionally gives false reading. Second one confirms.
ping -c 1 xxx.xxx.xxx.xxx > /tmp/pingtest 2> /dev/null
if [ $? != 0 ] ; then
date >> /tmp/pingtest
mail -s "NETWORK TEST: failed first test" david < /tmp/pingtest
ping -c 1 xxx.xxx.xxx.xxx >> /tmp/pingtest 2> /dev/null
if [ $? != 0 ] ; then
date >> /tmp/pingtest
mail -s "URGENT: CHECK NETWORK STATUS" david < /tmp/pingtest
fi
fi
I've just changed providers, and now I'm getting lots of failed tests,
even though my apache log suggests the system is up. "lots" = about 10 per
hour.
Does this indicate a network problem, or should I come up with a better
script?
thanks, David.
