Hi folks. I started to play with tc+htb last week, and I must confess that this thing is really driving me nuts. All we want to do is control bw, with no borrowing. In order to get the feeling on this subject, I have setup the following test bed. ---A---B---C--- On B: eth0 connecting A and eth1 connecting C. The script. tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 50 tc class add dev eth0 parent 1: classid 1:1 htb rate 32kbit ceil 32kbit tc filter add dev eth0 protocol ip parent 1:0 prio 100 u32 match ip src 10.4.0.0/16 match ip dst 0.0.0.0/0 classid 1:1
Should be src 192.168.0.0/24. Andy.
If I try to transfer a 1M file from C to A: [root@localpost tmp]# wget 192.168.0.23/1M --09:22:32-- http://192.168.0.23/1M => `1M.8' Connecting to 192.168.0.23:80... connected. HTTP request sent, awaiting response... 200 OK Length: 1,024,000 [text/plain] 100%[=====================>] 1,024,000 183.12K/s ETA 00:00 09:22:38 (182.88 KB/s) - `1M' saved [1,024,000/1,024,000] Wasn't it supposed to be around the 32KB/s? If I play with the numbers (rate=ceil) I get the following results: 128k ==> 404.78 KB/s 64k ==> 337.9 KB/s 16k ==> 68.86 KB/s 8k ==> 31.12 KB/s 1k ==> 3.77 KB/s I even tried to set the rate to 1kbps in root, but also led to pretty much the same results. With no qdisc, the rate will go close to 1000 KB/s B machine: 2.6.11-1.1369_FC4 iproute-2.6.11-1 TC HTB version 3.3 I have no clue on what I am doing wrong. Could anyone browse the above script and give me hint?
