Hi Members,

I wrote below script to monitor ssh traffic

+++++++++++++++++++++++++++++++++++++++++++
a=$(/usr/bin/sudo /sbin/iptables -vL|/bin/grep ':ssh'|/bin/awk '{print $1}')
if [ $a -gt 3 ]; then
echo "SSH aatempt is TOO High | $a"
exit 2
else
if [ $a -gt 2 ]; then
echo "SSH aatempt is Average | $a"
exit 1
else
echo "No SSH attempts | $a"
exit 0
fi
fi
exit 3
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++

This script is working fine on shell and returning "SSH attempt is too
high" . But when i run it via nagios the output returned OK and print "No
SSH attempts".

What I can notice that variable a not holding any value while running via
nagios , while its working fine when running via shell.

Can you please drive me in right direction ?


Thanks
