you are right , ping test takes long time..i modified and defined some defaults(for exa ping test about send 4 echo packet check in script)..
now you can give a ping try count for first parameter and then see the results..(actually 50 try requires more times but if you want to test in long time period then maybe you must specify 50 100 or 200 or more than parameter..)
so in script , ping tries transmit packets to target with 2 seconds intervals and 4 packets
first(prestart control) ping test takes about four seconds(normally about 1 second per packet or under 1 second ,, of course it may vary depending on various factors however) if target is avaliable and must must not be resulotion problem [ default timeout is 20 second ].but we defined packet size then it takes about 10 seconds + 4*1 second (per packet) = about 14 seconds.
lets look belows.
# if you dont have access to host..(some waits target host is non-accessable)

# time ping -s 192.168.56.112 56 4

at the now,you must you can try and use to a specifying parameter with new script..
for example
Code:
# ./testping.sh 2 hostlist
this means that you want to try for Number of 4-pack counts[this is defaul in script] * 2 count..
Code:
#!/usr/bin/bash
## justdoit ## ping test on SunOS ##
if [ $# != 2 ] ; then echo "usage $0 'packetcount' hostlistfile" ; exit 0 ; fi
if [[ $(echo $1|grep [^0-9]) ]] ; then echo "first parameter '$1' is not digit!!";exit 1;fi
sleep=2 ; c=$1 ; control=4 ; # count for packets
while read -r host ; do
printf "%s" "testing access to $host ...? "
(sleep $sleep;ping -s $host 56 $control > /dev/null 2>&1) &
pid=$! ; wait $pid
if [ $? -ne 0 ] ; then
printf "%s\n" "FAIL!! "
else
>tmppg
printf "%s\n" "SUCCESS "
## pinging try ##
printf "%s" "pinging try "
for((j=0;j<$c;j++)); do printf "%c" ".";sleep $sleep; ping -s $host 56 $control >>tmppg;done;
printf "%s\n" " OK"
nawk -F, -v c=$1 -v host=$host -v sleep=$sleep '/packets/{sub("% packet loss","",$3)}{t+=$3}
END{if(t>50*c) {system("opcmsg object=PING a=OS msg_grp=OpC severity=critical msg_text=\"PING BROKEN on "host"\"");
print "ping problem in \""host"\" !!\nping loss \"%"t" of %"100*c"\" for at "c" packet tries in "sleep" seconds intervals"}
