Hi,

I am following the HTB user manual and testing HTB on my local lan, using the rules given in the manual. I applied the rules in my eth0 and limited it to 100kbps, but when I tried to wget a file from another machine it came at 1mbps, Here are the commands and the settings. Did I do any thing stupid or is this supposed to work that way?

1. The commands

tc qdisc add dev eth0 root handle 1: htb default 12
tc class add dev eth0 parent 1: classid 1:1 htb rate 100kbps ceil 100kbps
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 30kbps ceil 100kbps
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 10kbps ceil 100kbps
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 60kbps ceil 100kbps
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst 192.168.3.90 match ip dport 8080 0xffff flowid 1:10
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src 192.168.3.92 flowid 1:11
tc qdisc add dev eth0 parent 1:10 handle 20: pfifo limit 5
tc qdisc add dev eth0 parent 1:11 handle 30: pfifo limit 5
tc qdisc add dev eth0 parent 1:12 handle 40: sfq perturb 10


2. wget output

raj@indus:~$ wget -O /dev/null http://penguin:8080/knoppix
--14:01:45--  http://penguin:8080/knoppix
           => `/dev/null'

As you can see from the command and wget output i limited the outgoing bandwidth to 100kbps but i am still getting 1Mbps. Is this what I am supposed to get or did I do some thing really stupid?

I have attached the full logs as a text file also incase my mail client messes up the output.

Thanks in Advance,
raj
