openwrt看IP流量

可以利用iptable來實現的，看附件的腳本。

把他放到路由器里面，然后運行。

#!/bin/sh
echo "Collecting data..."
echo ""
cat /proc/net/arp | grep : | grep ^192 | grep -v 00:00:00:00:00:00| awk '{print $1}'> mac-arp
iptables -N UPLOAD
iptables -N DOWNLOAD
while read line;do iptables -I FORWARD 1 -s $line -j UPLOAD;done < mac-arp
while read line;do iptables -I FORWARD 1 -d $line -j DOWNLOAD;done < mac-arp

sleep 1

echo "Download speed:"
echo ""
iptables -nvx -L FORWARD | grep DOWNLOAD | awk '{print $2/1024/1" KB/s ",$1/10" packets/s", $9}' | sort -n -r
echo ""
echo "Upload speed:"
echo ""
iptables -nvx -L FORWARD | grep UPLOAD | awk '{print $2/1024/1" KB/s ",$1/10" packets/s", $8}' | sort -n -r

while read line;do iptables -D FORWARD -s $line -j UPLOAD;done < mac-arp
while read line;do iptables -D FORWARD -d $line -j DOWNLOAD;done < mac-arp
iptables -X UPLOAD
iptables -X DOWNLOAD
