Added IPv6 support

Thanks for the check. I like to be able to check both IPv6 and IPv4, so that is what the edit below does: (Paths used in this script are adapted for Debian/ Ubuntu based systems.) #!/bin/bash case $# in 1) case $1 in -4) IPT='/sbin/iptables' ;; -6) IPT='/sbin/ip6tables' ;; *) ;; esac GREP='/bin/grep' AWK='/usr/bin/awk' EXPR='/usr/bin/expr' WC='/usr/bin/wc' STAT=0 OUTPUT='' CHAINS=`$IPT -nvL | $GREP 'Chain' | $AWK '{ print $2 }'` for CHAIN in $CHAINS ; do if [ "$CHAIN" != 'FORWARD' ] && [ "$CHAIN" != 'OUTPUT' ] && [ `$EXPR substr $CHAIN 1 4` != "LOG_" ] ; then CNT=`expr $($IPT -S $CHAIN | $WC -l) '-' 1` if [ $CNT -eq 0 ] ; then OUTPUT="${OUTPUT}ERROR $CHAIN $CNT rules!" STAT=2 else OUTPUT="${OUTPUT}OK $CHAIN $CNT rules" fi fi done echo $OUTPUT exit $STAT ;; *) echo "Usage: $0 [-4][-6]" exit 1 ;; esac
