Homework and Emergencies Emergency UNIX and Linux Support Script for pinging continuously Post 302970266 by jim mcnamara on Monday 4th of April 2016 02:22:26 PM

Okay. Since ping -c 1 -w 5 (where -c is the number of ping attempts and -w is the timeout in seconds) seems to be the AIX way to ping and limit the time it takes to complete the operation:

One day is 86400 seconds.

Code:
#!/bin/ksh    
now=`date +%s`
stop=$(( $now +  86400 ))
while true
do
   now=`$date +%s`
   if [ $now  -gt $stop ] 
   then
       break
   fi
   ping -c 1 -w 5 AIXservername 
   [ $! -eq 0 ] && OK='pass' || OK='fail'
   echo "$OK at `$date`" >>mylogfile
done

See if that meets your needs.
