Hey all. I'm trying to set up QoS using the HTB qdisc in a very basic setup, but it the example shown in the howto doesn't seem to be working. While the packets show up in the correct classes, they appear to be completely ignoring the rates, meaning nothing gets shaped. My setup is that I've got a a bunch of machines behind my firewall/router: 1.2.3.1 +----------------------------+ 10.0.0.1 1.2.3.2 -----+eth0 firewall/router eth1+--- 10.0.0.2 1.2.3.3 +----------------------------+ 10.0.0.3 10.0.0.1 is nat'd to 1.2.3.1, 10.0.0.2 to 1.2.3.2, etc. eth0 is attached to a 768Kbit DSL line, and eth1 to a 100Mb ethernet. I want to limit the output of 10.0.0.1, but let it borrow from everybody else's bandwidth when the bandwidth would go unused. HTB seems ideal for this, and the TC stuff is pretty much identical to the basic one in the howto: tc qdisc add dev eth0 handle 1: root htb default 11 tc class add dev eth0 parent 1: classid 1:1 htb rate 768kbit ceil 768kbit burst 15k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 160kbit ceil 768kbit burst 15k tc class add dev eth0 parent 1:1 classid 1:11 htb rate 608kbit ceil 768kbit burst 15k tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 tc qdisc add dev eth0 parent 1:11 handle 10: sfq perturb 10 tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src 1.2.3.1 flowid 1:10 When I start sucking a lot of data from 10.0.0.1 and 10.0.0.2 from outside the firewall, the packets end up in the correct classes (judging by tc -s -d show dev eth0). But they also are processed at equal rates, not at the 160:608 ratio I've specified. What am I doing wrong?
