LARTC - Sep 2006 - simple question

Hello
everybody,

I''m trying to set up netem on a SuSE box (kernel 2.6.16), but
I''m having some weird problems, considering that on my Gentoo laptop
(kernel 2.6.17) it worked
fine.

If I write:

# tc qdisc add dev eth0 root netem delay 20ms loss 20%

and then try pinging another machine over eth0, I get a 24ms delay but no packet
loss (while on my laptop I get 21ms and a correct packet
loss).

But what I''m sure you''ll be able to clarify is this:
what''s wrong with this command:

# tc qdisc add dev eth0 root handle 1: netem delay 20ms

# tc qdisc add dev eth0 parent 1:1 handle 10: netem loss 20%

That is what phpnetemgui tries to do, and as far as I read it should be the same
as the previous command, but in both the box and my laptop I get only the packet
loss...

Can anyone help me?

Thanks in advance.

Ferdinando

Hi All:

I have a GRE tunnel that I want to use tc on. This is simple and straight
forward.
I then want to use tc on the ppp1 interface and prioritize outgoing ESP
packets. The GRE tunnel is encapsulated inside the IPSec tunnel.

To do this, do I have two copmpeltely separate sets of traffic control rules
and filters? One for the GRE tunnel interface and one for the ppp1 interface?

Cheers,
John
