Operating Systems Linux Red Hat script for continous ping Post 302627197 by rbatte1 on Friday 20th of April 2012 10:01:29 AM

Something like:-
Code:
ping -c 1 10.20.30.40

...will get you a one second ping to reconcile, or
Code:
ping -c 86400 10.20.30.40

... will give you 24Hrs. of output.

If you ran the latter with a cron entry thus:-

Code:
0 0 * * * ping -c 86400 10.20.30.40 > /tmp/`date +%Y_%m_%d`

The, at a later date you could:-

Code:
grep "packets transmitted" /tmp/output_file read in p t out rest

if [ $in -ne $out ]
then
   echo "We have a problem"
else
   echo "All okay"
fi




Does that help at all?
