Good day all
So at log last I did my script
We have a 256kbite connection.This scrip runs on my gateway box(the same
for script for eth1(ext) and eth0(int)
I want to limit all other traffic to 10kbites but when I do it I give me
this error:
HTB quantum of class 10034 is to small.consider r2q <7>htb*g j=42801780
Here is my script.If you have any Idea to better it let me know.Its a
bit from here and there and some of my own
#!/bin/bash
DEV=eth1
RATEUP=256
#To get stats
if [ "$1" = "stats" ]
then
echo "[qdisc]"
tc -s qdisc show dev $DEV
echo "[class]"
tc -s class show dev $DEV
#echo "[filter]"
#tc -s filter show dev $DEV
#echo "[iptables]"
exit
fi
#Reset
tc qdisc del dev $DEV root
if [ "$1" = "stop" ]
then
echo "Shaping removed on $DEV."
exit
fi
