Hi again,

sorry for my late response. Could you give us also the output of

tc -s -d qdisc show dev eth0
tc filter show dev eth0

It is very strange that the rate and ceil from class 1:10 are set to 512Kbit but the class's rate goes over 3,5Mbits!! ¿Maybe it is a bug?
I'm preparing a similar setup (a linux wan router on a 100Mbit lan with 5Mbps upload/dowload to the Internet. We will see if I run into the same issues...


Regards,
Eric Janz

Re: htb traffic shaping problem (Charlie Meyer)





Eric,
I've attached the output from the command you requested below.
I'm using kernel 2.6.17.12 and tc version ss060323.  I'm have a nforce4
onboard giggabit controller using the forcedeth driver, if that makes a
difference.

Charlie,
I'll take a look at the Apache model for throttling, thanks.  I was going
for tc because was going to try to add additional shaping to non-apache
traffic once I got it working correctly.

Thanks,
-Ryan Power
