Hi, I am fairly new to routing and traffic control but I with the help of the lartc howto I managed to setup a bridge with htb traffic control. The traffic shapping does not seem to work as I expected and I would really appreciate if somebody can tell my why this is the case. My setup: I have a DSL router connecting a /28 network to the internet. I put a linux box with 2 ethernet cards between my router and the rest of the subnet. I set up the linux box as an ethernet bridge where the 2 ethernet cards has no ip address and the bridge has an ip address. I patched the kernel with the IMQ patch so that I can shape incoming traffic. eth0 is connected to the router and eth1 is connect to the rest of the public subnet. I have an iptables rule that routes all traffic on eth1 to the imq device. I started with a very simple htb setup to make testing easier: #!/bin/bash tc qdisc del dev imq0 root ip link set imq0 down tc qdisc add dev imq0 root handle 1: htb default 12 tc class add dev imq0 parent 1: classid 1:1 htb rate 128kbit ceil 128kbit tc class add dev imq0 parent 1:1 classid 1:10 htb rate 64kbit ceil 128kbit tc class add dev imq0 parent 1:1 classid 1:11 htb rate 32kbit ceil 128kbit tc class add dev imq0 parent 1:1 classid 1:12 htb rate 32kbit ceil 128kbit tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 \ match ip dst 196.44.35.53 flowid 1:10 tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 \ match ip dst 196.44.35.54 flowid 1:10 tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 \ match ip dst 196.44.35.55 flowid 1:10 tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 \ match ip dst 196.44.35.51 flowid 1:11 tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 \ match ip dst 196.44.35.52 flowid 1:11 iptables -F iptables -X iptables -t mangle -A PREROUTING -i eth1 -j IMQ --todev 0 ip link set imq0 up My problem is that all traffic seems to go through the default htb class although there are lots of traffic matching the other 2 classes. root@griet root # tc -d -s class show dev imq0 class htb 1:1 root prio 0 rate 128Kbit ceil 128Kbit burst 1753b/8 mpu 0b cburst 1753b/8 mpu 0b quantum 1638 level 3 Sent 13194 bytes 147 pkts (dropped 0, overlimits 0) rate 7bps lended: 0 borrowed: 0 giants: 0 injects: 0 tokens: 101 ctokens: 101 class htb 1:10 parent 1:1 prio 0 rate 64Kbit ceil 128Kbit burst 1679b/8 mpu 0b cburst 1753b/8 mpu 0b quantum 819 level 0 Sent 0 bytes 0 pkts (dropped 0, overlimits 0) lended: 0 borrowed: 0 giants: 0 injects: 0 tokens: 205 ctokens: 107 class htb 1:11 parent 1:1 prio 0 rate 32Kbit ceil 128Kbit burst 1638b/8 mpu 0b cburst 1753b/8 mpu 0b quantum 409 level 0 Sent 0 bytes 0 pkts (dropped 0, overlimits 0) lended: 0 borrowed: 0 giants: 0 injects: 0 tokens: 400 ctokens: 107 class htb 1:12 parent 1:1 prio 0 rate 32Kbit ceil 128Kbit burst 1638b/8 mpu 0b cburst 1753b/8 mpu 0b quantum 409 level 0 Sent 13194 bytes 147 pkts (dropped 0, overlimits 0) rate 7bps lended: 147 borrowed: 0 giants: 0 injects: 0 tokens: 373 ctokens: 101 Any help would be greatly appreciated. -- Roché Compaan Upfront Systems http://www.upfrontsystems.co.za _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
