Hi all,
I use a Debian Woody with Kernel 2.4.18 patched with the HTB queue. I use
the tc binay given within the HTB targz. Iptables 1.2.6a
I wrote this script based on the ADSL Bandwith management howto :
DEV=eth0
RATEUP=128
tc qdisc add dev $DEV root handle 1: htb default 22
tc class add dev $DEV parent 1: classid 1:1 htb rate ${RATEUP}kbit
tc class add dev $DEV parent 1:1 classid 1:20 htb rate $[$RATEUP/7]kbit
ceil ${RATEUP}kbit prio 0
tc class add dev $DEV parent 1:1 classid 1:21 htb rate $[$RATEUP/7]kbit
ceil 88kbit prio 1
tc class add dev $DEV parent 1:1 classid 1:22 htb rate $[$RATEUP/7]kbit
ceil 88kbit prio 2
tc qdisc add dev $DEV parent 1:20 handle 20: sfq perturb 10
tc qdisc add dev $DEV parent 1:21 handle 21: sfq perturb 10
tc qdisc add dev $DEV parent 1:22 handle 22: sfq perturb 10
tc filter add dev $DEV parent 1:0 prio 0 protocol ip handle 20 fw flowid 1:20
tc filter add dev $DEV parent 1:0 prio 0 protocol ip handle 21 fw flowid 1:21
tc filter add dev $DEV parent 1:0 prio 0 protocol ip handle 22 fw flowid 1:22
iptables -t mangle -N MYSHAPER-OUT
iptables -t mangle -I POSTROUTING -o $DEV -j MYSHAPER-OUT
iptables -t mangle -A MYSHAPER-OUT -p tcp --dport 20 -j MARK --set-mark 22
iptables -t mangle -A MYSHAPER-OUT -p icmp -j MARK --set-mark 20
iptables -t mangle -A MYSHAPER-OUT -p udp -j MARK --set-mark 21
I transfered a file by ftp. The packets was sent through the class 22 and
its bandwith limited to 88kbits, which is normal. But i sent pings and
thoose packets were sent through the class 22 too which is not normal due
to the mangle packets marking.
I know which class was used by looking the tc classes status. Why icmp
packets was not sent through class 20 ?
Any help would be appriciated. Thanks and have a nice day.
