IPTables

Решил собирать трафик по IPTables.
Статью нашел по теме: http://www.opennet.ru/base/net/iptables_stat.txt.html

Только работает она не так:
# eth0-stat ; cat eth0.dat
2
0

Скачал полтора мегабайта:
# eth0-stat ; cat eth0.dat
2
0

-----------------------------------

# cat `which eth0-stat`
#!/bin/sh

IPT=/sbin/iptables
GREP=/bin/grep
AWK=/bin/awk

function getStat
{
        _INPUT=`$IPT -L INPUT -x -v |$GREP $1| $AWK '{print($2)}'`
        _FWD_IN=`$IPT -L FORWARD -x -v|$GREP $1|$GREP fwd_in| $AWK '{print($2)}'`
        _RX=`expr $_INPUT + $_FWD_IN`
        RX=`expr $_RX \/ 300` # one time per 5 mins = 300 secs

        _OUTPUT=`$IPT -L OUTPUT -x -v |$GREP $1| $AWK '{print($2)}'`
        _FWD_OUT=`$IPT -L FORWARD -x -v |$GREP $1|$GREP fwd_out| $AWK '{print($2)}'`    _TX=`expr $_OUTPUT + $_FWD_OUT`
        TX=`expr $_TX \/ 300`

        echo $RX > $2
        echo $TX >> $2
}

getStat eth0 /mine/temp/eth0.dat
#$IPT -Z
