Ne mozhesh da flushnesh samo edin rule. dazhe nemozhesh da flushnesh CHAIN
(ako si spomniam pravilno), -F shte ti zabyrshe wsichki chainove :(
Osven tova za da zasichash trafika s mrtg ne ti e nuzhno da flusvash nishto,
mrtg e napraveno taka che da otchita po-princip postoianno uvelichavashti

Ako na niakoi mu triabva da otchita trafik minal prez niakoe ustroistvo na
localnata mashina kydeto e mrtg-to, mozhe da izpolzva tozi script:
--------------
#!/bin/sh
 
PATH="/bin:/sbin:/usr/bin:/usr/sbin"
 
if [ $# -eq 0 ]; then
    echo "Usage: $0 dev"
    exit
fi
 
DEV=$1
 
IN=$(cat /proc/net/dev | grep $DEV | sed -e "s|  | |g;s|  | |g;s|  | |g;s|  | |g;s|^ +||g;s|: |:|" | cut -d" " -f2 | sed -e "s|.*:||")
OUT=$(cat /proc/net/dev | grep $DEV | sed -e "s|  | |g;s|  | |g;s|  | |g;s|  | |g;s|^ +||g;s|: |:|" | cut -d" " -f10)
 
if [ "$IN" == "" ]; then echo 0; else echo $IN; fi
if [ "$OUT" == "" ]; then echo 0; else echo $OUT; fi
uptime | sed -e "s|.* up ||"
echo "$DEV@`cat /etc/HOSTNAME`" 

Tozi vadi statistikite ot IPCHAINS
----------------------------
#!/bin/sh
 
PATH="/bin:/sbin:/usr/bin:/usr/sbin"
 
input_chain="input";
output_chain="output";
 
input=$(ipchains -L $input_chain -x -v -n | head -1)
input_bytes=$(echo $input | sed -e "s/.*, //;s| .*||")
 
output=$(ipchains -L $output_chain -x -v -n | head -1)
output_bytes=$(echo $output | sed -e "s/.*, //;s| .*||")
 
echo $input_bytes
echo $output_bytes
uptime | cut -b 14-80
cat /etc/HOSTNAME
