[LARTC] limiting doesn't work

["Stephan M. Ott" <webmaster@familie-ott.info>]

Hi folks,

I read the fantastic LARTC How-to and after that i tried to limit one
host in my LAN for both down-and upload bandwidth usage.
I took section 15.9. and added uplink-limiting as I understood it from
the previous chapters.
Unfortunately it doesn't work.
I ran the script and went to the specified PC, started a download, and
watched the rate. The rate was always about 2000 kbit/s, though I
defined (well, at least I thought so) 768 kbit/s as maximum rate.
Can anyone please look at the script and tell me, what must be corrected
in order for it to work ?
Thanks in advance.

This is the script:

#!/bin/bash
LIMITDOWNv8
LIMITUP–
DEV=ppp0

# clean up qdiscs
tc qdisc del dev $DEV root 2> /dev/null > /dev/null

# limit up- and downlink for benni
tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 2mbit
tc class add dev $DEV parent 1: classid 1:1 cbq rate ${LIMITDOWN}kbit
allot 1500 prio 5 bounded isolated
tc class add dev $DEV parent 1: classid 1:2 cbq rate ${LIMITUP}kbit
allot 1500 prio 5 avpkt 1000
tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip dst
192.168.0.51 flowid 1:1
tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip src
192.168.0.51 flowid 1:2
#tc qdisc add dev $DEV parent 1:1 sqf perturb 10
#tc qdisc add dev $DEV parent 1:2 sqf perturb 10

I commented out the last 2 lines for testing so that the rate is always
limited.

Any ideas ?

Thanks.

Stephan
