Sorry, I didn't undertand very well the thing :-P. Also, I haven't got=20
permanent access to other's pc of the network (they're not mine
 ;-)!) and that's the reason because I posted the counters as is.=20

Anyway, here you can all see the problem:

# tc -s -d qdisc
qdisc ingress ffff: dev eth0 ----------------
 Sent 5109350 bytes 13696 pkts (dropped 935, overlimits 0)

And the only tc rules I executed were:

tc qdisc add dev eth0 handle ffff: ingress
tc filter add dev eth0 parent ffff: protocol ip prio 10 u32 \
	match ip src 192.168..0.0/24 \
	match ip dst 192.168..0.0/24 \
	police rate 100mbit burst 10k drop flowid :2

In this test I did is just overing the kde's taskbar and clicking in the K=
=20
menu. BTW, I'll tell you that many operations work fine, but there'are some=
=20
(as the one's Ive just refered to) that are rather slow.

Now, let's see what is the maximun ssh speed:
# scp=20
edulix@192.168.0.7:/home/edulix/videos/prodigy90_med.mpg /home/edulix/temp/
Warning: Permanently added '192.168.0.7' (RSA) to the list of known hosts.
edulix@192.168.0.7's password:
prodigy90_med.mpg                                     11%  992KB  45.0KB/s =
 =20

Mamma mia! That must demostrate the problem hehe. In normal conditions that=
=20
video is transfered in less than 3 seconds at 7-8 Mb/s! After doing that, I=
=20
can see:
# tc -s -d qdisc
qdisc ingress ffff: dev eth0 ----------------
 Sent 30133742 bytes 88401 pkts (dropped 4792, overlimits 0)

Cheers,
