lug-bg: HTB problem

["Qsin" <qsin@xxxxxxxxxxxx>]

Нужно ми беше решение за HTB подобно на описания от Никола Колев в

http://www.mail-archive.com/lug-bg@xxxxxxxxxxxxxxxxxx/msg15376.html

Като начало реших да опитам скрипта без никакво изменение:

#!/bin/bash



# изходящ интерфейс

dev=eth0



# път до tc

tc=/sbin/tc



htb_stats ()

{

# show class stats

$tc -s -d class show dev $dev

# show qdisc stats

$tc -s -d qdisc show dev $dev

} #htb_stats



htb_stop ()

{

# remove all qdiscs from $dev

$tc qdisc del dev $dev root &>/dev/null

} # htb_stop



htb_start ()

{

set -x



# attach root discipline

$tc qdisc add dev $dev root handle 1: htb default 1000 r2q 10



# клас за клиент с гарантирани 256Кбита

$tc class add dev $dev parent 1: classid 1:10 htb rate 256Kbit

$tc filter add dev $dev protocol ip parent 1:0 prio 4 u32 \

match ip dst 192.168.0.119 flowid 1:10

$tc qdisc add dev $dev parent 1:10 handle 10: sfq perturb 20



# клас за клиент с гарантирани 128Кбита

$tc class add dev $dev parent 1: classid 1:20 htb rate 128Kbit

$tc filter add dev $dev protocol ip parent 1:0 prio 4 u32 \

match ip dst 192.168.0.210 flowid 1:20

$tc qdisc add dev $dev parent 1:20 handle 20: sfq perturb 20



# клас за клиент с гарантирани 64Кбита

$tc class add dev $dev parent 1: classid 1:30 htb rate 64Kbit

$tc filter add dev $dev protocol ip parent 1:0 prio 4 u32 \

match ip dst 192.168.0.11 flowid 1:30

$tc qdisc add dev $dev parent 1:30 handle 30: sfq perturb 20



# default клас, в който попадат всички останали

# за него заделяме 64Кбита



$tc class add dev $dev parent 1:0 classid 1:1000 htb \

rate 64Kbit ceil 64Kbit

$tc qdisc add dev $dev parent 1:1000 handle 1000: sfq perturb 20

} # htb_start



case "$1" in



    ### START ###

        start)

            htb_start

        ;;



    ### STOP ###

        stop)

            htb_stop

        ;;



    ### RESTART ###

        restart)

            $0 stop

            $0 start

        ;;



    ### STATS ###

        stats)

            htb_stats

        ;;



    ### default ###

        *)

    echo "Usage: " `basename $0` "{start|stop|restart|stats}"

esac





При което получих следното със рязко забавяне на машината:



/htb.3 start



+ /sbin/tc qdisc add dev eth0 root handle 1: htb default 1000 r2q 10

+ /sbin/tc class add dev eth0 parent 1: classid 1:10 htb rate 256Kbit

+ /sbin/tc filter add dev eth0 protocol ip parent 1:0 prio 4 u32 match ip
dst 192.168.0.119 flowid 1:10

RTNETLINK answers: Invalid argument

+ /sbin/tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 20

+ /sbin/tc class add dev eth0 parent 1: classid 1:20 htb rate 128Kbit

+ /sbin/tc filter add dev eth0 protocol ip parent 1:0 prio 4 u32 match ip
dst 192.168.0.210 flowid 1:20

RTNETLINK answers: Invalid argument

+ /sbin/tc qdisc add dev eth0 parent 1:20 handle 20: sfq perturb 20

+ /sbin/tc class add dev eth0 parent 1: classid 1:30 htb rate 64Kbit

+ /sbin/tc filter add dev eth0 protocol ip parent 1:0 prio 4 u32 match ip
dst 192.168.0.11 flowid 1:30

RTNETLINK answers: Invalid argument

+ /sbin/tc qdisc add dev eth0 parent 1:30 handle 30: sfq perturb 20

+ /sbin/tc class add dev eth0 parent 1:0 classid 1:1000 htb rate 64Kbit ceil
64Kbit

+ /sbin/tc qdisc add dev eth0 parent 1:1000 handle 1000: sfq perturb 20



А и трафика през мойта машина (192.168.0.210) нямаще нищо общо с 128 Kbit
