HP-UX Script

Hi,

I just wrote some script in HP-UX regarding the ECHO ping.

when I execute a command
IP="202.202.202.202 (example)
and then
/usr/sbin/ping $IP -n 1 |wc -c

a return value is 226.

so when I change the IP to a fake IP let say IP=202.202.202.203 and I execute a command
/usr/sbin/ping $IP -n 1 |wc -c

a return value is 135.

After tht I execute a same command with real IP so I get return value is 230.

So my question i how can I put a two condition where are if return values is 226 OR 230 so a retval=1. My example script

IP="202.202.202.202"

CONTACT=$(/usr/sbin/ping $IP -n 1 | wc -c)
if [ "$CONTACT" -eq 226 ]
then
retval=0
else
retval=1
fi
echo "Destination Status" $retval
return retval

Hello,

Try :

CONTACT=$(/usr/sbin/ping $IP -n 1 | wc -c)
if [ "$CONTACT" -eq 226 -o "$CONTACT" -eq 230 ]
then
retval=0
else
retval=1
fi
echo "Destination Status" $retval
return retval

Then you will have retval = 0 for CONTACT = 226 OR 230.

Hi,
for a limited number of return values, you could make use of a case-structure, e.g.:

case $CONTACT in
226) retval=0;;
230) retval=0;;
*) retval=1;;
esac

Hi,

If you are looking for a script to monitor the network
check this

#!/bin/sh
IP="202.202.202.202"
CONTACT=$(/usr/sbin/ping $IP -n 1 |tail -2 |grep "%" |tail -1 |awk -F"," '{print $3}'|awk -F"%" '{print $1}')

if [ "$CONTACT" -lt 100 ]
then
echo "LINK UP"
else
echo "LINK Down"
fi

Hmm, besides this discussion about checking for multiple cases... looks like you are checking for the byte count of the messages returned by ping? Seems to be a liitle bit risky INHO...

What about...

ping $IP -n 1 | grep -q "bytes from"
retval=$?
echo "Destination Status" $retval
return retval

Best regards...
