[LARTC] Strange error!?

[Cow]

I was using this setup and it worked fine untill i executed up2date in
Redhat and updated a lot of the packages in linux.

When i run the following script i get an error, which i pasted bellow.

Script i run:
        iptables -t mangle -A FORWARD -s 171.100.20.110 -j
MARK --set-mark 28
        iptables -t mangle -A POSTROUTING -s ! 171.100.20.96/27 -d
171.100.20.110 -j MARK --set-mark 29

        #Root QDiscs
        #### upstream
        tc qdisc add dev $WAN root handle 1: htb default 16
        #### downstream
        tc qdisc add dev $LAN root handle 1: htb default 16

        tc qdisc add dev $WAN parent 1:11 handle 11: sfq perturb 10

THIS HAS WORKED BEFORE!

Now the error i get is:

Error: Qdisc "htb" is classless.
Error: Qdisc "htb" is classless.

Do you have kernel support for HTB?

As i said this has worked before, a few days ago it was running
perfectly.

But let's pretend i dont, how do i check if my kernel supports HTB?

In '/boot' directory you should have a file named 'config-xxx-(kernel 
version)'. Open it and there you have to look for a line like that:

CONFIG_NET_SCH_HTB=y
or
CONFIG_NET_SCH_HTB=m

Also if you have htb as a module, be sure that it is loaded.

I have the following in config:
CONFIG_NET_SCH_HTB=m

So should be ok.

Dunno if the module is loaded, but i found it here:
/lib/modules/2.4.20-8/kernel/net/sched/sch_htb.o

Seems like it's loaded and running:

Maybe it updated the tc binary to one that doesn't know about HTB.

Try posting to a redhat list.
