Set a ping program

[hangyu]

I would like to add a ping program that ping from host A to host B , the ping schedule is from 09:00am to 05:00pm daily , and periodically send a current time to the ping log ( so that I can easily to trace the time ) , can provide a simple script for me ?
what I do now is :
schedule job 1 : submit a ping job at 09:00am daily and kill it at 05:00pm
schedule job 2 : set a schedule job to run hourly "date >> ping.log"

hi,

since by default, ping waits for 1 sec between the sending of each packet, this can be easily implemented.

#!/bin/sh
export PINGLOG=/home/yd/logfiles/ping-$(date +%a)
cat /dev/null > $PINGLOG
i=1
while [ $i -le 8 ]
do
ping hostb -c 3600 >> $PINGLOG
date >> $PINGLOG
i=`expr $i + 1`
done

hope this helps!
kind regards
yogeeraj

Hi hangyu

This is "ping_host.csh" script
#!/bin/csh -f
/usr/sbin/ping -s HOSTNAME

This is kill_ping.csh script:
#!/bin/csh -f
set PR_ID = `/bin/ps -ef | grep ping | grep -v grep | grep HOSTNAME | awk '{print $2}'`
kill -9 $PR_ID

This is crontab line:

00 9 * * 1-5 ping_host.csh > ping.log 2>&1
00 17 * * 1-5 kill_ping.csh

Best Regards
Ernesto.
