i have a simple set of rules to limit download speed from port 80, but when i download (using wget) that speed is broken by a factor of 56 times..
so i reckon i'm doing something wrong.
tc rules:
Code:
sudo /sbin/tc qdisc del dev ppp0 root
sudo /sbin/tc qdisc add dev ppp0 root handle 1: htb default 30
sudo /sbin/tc class add dev ppp0 parent 1: classid 1:1 htb rate 1Kbit
sudo /sbin/tc filter add dev ppp0 protocol ip parent 1:0 prio 1 u32 match ip dport 80 0xffff flowid 1:1
wget:
Code:
wget http://ftp.au.debian.org/debian/dists/squeeze/main/binary-armel/Packages.gz

i can see the rule is being triggered, it's just not limiting the speed

any hints ?
