[LARTC] unknown qdisc 'htb' ???

[LARTC] unknown qdisc 'htb' ???

[Patrick Van Acker]

Hello,

I'd like to try out HTB for traffic shaping.

I have a test machine with Redhat 7.2 (kernel 2.4.10), I've downloaded 
kernel 2.4.17, applied the patch from http://luxik.cdi.cz/~devik/qos/htb/, 
recompiled the kernel (checked the option to use HTB in make menuconfig), 
and rebooted with the new kernel.

When I try to add some rules with HTB (f.i. tc qdisc add dev eth0 root 
handle 1: htb default 1:1 ), I got the following error message:
Unknown qdisc "htb", hence option "default" is unparsable

Obviously, this is not what I want :-)

What is going wrong here?

Regards,
Patrick

Have you patched and recompiled iproute2 ?

Hi.
You are probably using an old version of tc,
try downloading the precompiled binary from the
htb site or get the sources at http://diffserv.sourceforge.net/

Hello,

Could you tell me how did you solve your problem?
I have exactly the same problem but with this configuration:
 - linux 2.4.20 kernel, HTB option checked
 - iproute2-2.4.7-now-ss010824.tar.gz installed, which is the latest version I found at ftp://ftp.sunet.se/pub/Linux/ip-routing/, except for "try" or "do not use" versions.
I guess I do not need patching iproute2 and I'm not using an old version of tc either.

Or am I wrong somewhere?

Br,
    Emmanuel

Correct me if I'm wrong but I believe the "default" option requires a
class not a parent:class combo.  When I create an htb qdisc I use the
command:

tc qdisc add dev eth1 root handle 1: htb default 40

but I suppose in your case you could use:

tc qdisc add dev eth1 root handle 1: htb default 1
// I've tried the above command and it returns just fine

Well, in fact my exact line is:
tc qdisc add dev eth1 root handle 1: htb default 12
So it's the same than yours (sorry I hadn't noticed the slight 
difference with Patrick's line) but it doesn't work.
Thanks anyway.

You need to patch iproute2 for htb support. The patch can be found on the htb 
homepage.  Or use the binary found on the htb homepage or go to 
www.docum.org.  I have a tc binary on it with htb support on the download 
page.
