Documentation about iptables: ~:# man iptables
This scripts is intended to be used to check if your iptables rules are set correctly load at any time, I didn't find a better way to check if a server has your rules loaded so I check the number of configured rules and if they are less than they should be Nagios will send an alert using it notify service.

Hi...
I managed to get this somewhat operational on the local machine by adding the nagios user to the sudoers file..
nagios ALL= NOPASSWD: /sbin/iptables
Then I added the sudo to the plugin..
CHKIPTBLS=`sudo /sbin/iptables -n -t filter -L |wc -l`
However that only sorted out the local execution environment.. When I try to invoke from the foreign Nagios server, it still doesn't quite execute :(
[The Command]
/usr/local/nagios/libexec/check_nrpe -H {the_other_machine_ip} -c check_iprule_no -a RH-Firewall-1-INPUT 15
[The Output]
CRITICAL - Iptables are CRITICAL The Table RH-Firewall-1-INPUT and Chain has 0 rules configured
However it works nicely on the NRPE local machine..
[Output]
OK - Iptables are OK The Table RH-Firewall-1-INPUT and Chain has 28 rules configured
