Hello! I've been trying to write a traffic shaper for a 128kbit line with this setup : 5 computers that get dedicated bandwidth and the rest go in a pool with bigger priorities. I made the attached script, but it seems it doesn't work... It sends the traffic coming from the dedicated ips to the default class. Where is the error ? Will this setup work if the bandwidth is full ? Since it's not a guaranteed bandwidth can i put no ceiling but still all the ips to have their equal share ? I've set r2q to 1 (it's the smallest one possible, no ? ) and it receive warnings that the quantum is too small Thanks in advance.... Radu Here's the script : tc qdisc add dev eth1 root handle 1: htb default 14 r2q 1 tc class add dev eth1 parent 1: classid 1:1 htb rate 128kbit burst 2k tc class add dev eth1 parent 1:1 classid 1:10 htb rate 48kbit burst 2k tc class add dev eth1 parent 1:1 classid 1:20 htb rate 12kbit ceil 128kbit burst 2k tc class add dev eth1 parent 1:1 classid 1:30 htb rate 12kbit ceil 128kbit burst 2k tc class add dev eth1 parent 1:1 classid 1:40 htb rate 12kbit ceil 128kbit burst 2k tc class add dev eth1 parent 1:1 classid 1:50 htb rate 12kbit ceil 128kbit burst 2k tc class add dev eth1 parent 1:1 classid 1:11 htb rate 20kbit ceil 128kbit burst 2k tc class add dev eth1 parent 1:11 classid 1:12 htb rate 10kbit burst 2k tc class add dev eth1 parent 1:11 classid 1:13 htb rate 5kbit burst 2k tc class add dev eth1 parent 1:11 classid 1:14 htb rate 5kbit burst 2k tc qdisc add dev eth1 parent 1:20 handle 20: sfq perturb 15 tc qdisc add dev eth1 parent 1:30 handle 30: sfq perturb 15 tc qdisc add dev eth1 parent 1:40 handle 40: sfq perturb 15 tc qdisc add dev eth1 parent 1:50 handle 50: sfq perturb 15 tc qdisc add dev eth1 parent 1:12 handle 12: sfq perturb 15 tc qdisc add dev eth1 parent 1:13 handle 13: sfq perturb 15 tc qdisc add dev eth1 parent 1:14 handle 14: sfq perturb 15 tc filter add dev eth1 protocol ip parent 1: u32 match ip dst 192.168.0.45 flowid 1:20 tc filter add dev eth1 protocol ip parent 1: u32 match ip dst 192.168.0.4 flowid 1:30 tc filter add dev eth1 protocol ip parent 1: u32 match ip dst 192.168.0.50 flowid 1:40 tc filter add dev eth1 protocol ip parent 1: u32 match ip dst 192.168.0.38 flowid 1:50 tc filter add dev eth1 protocol ip parent 1: prio 1 u32 match ip sport 80 0xffff flowid 1:12 tc filter add dev eth1 protocol ip parent 1: prio 2 u32 match ip sport 25 0xffff flowid 1:13 tc filter add dev eth1 protocol ip parent 1: prio 3 u32 match ip sport 110 0xffff flowid 1:13
