HTB+SFQ
Hi folks,
I`ve a problem to use HTB and SFQ.
The first script, below, to show a simple configuration, does work
fine...!!!
But, in the second example, does not work, becouse i put more code to
clasify the traffic by protocol, http and ftp in this case.
Somebody can tell me the errors?
Thx, in advance.-

Problems setting up nested qdisc, feedback to LARTC HOWTO
Hi all,
based on the information in the "Linux Advanced Routing & Traffic
Control HOWTO", I was trying to set up traffic shaping on my firewall.
While I found the HOWTO very useful, in the process I ran into some
problems that I did not forsee: According to the HOWTO it seems that
it should have worked, even after spending some time going through the
sections looking for answers,

HTB Rate and Prio
Hi,
I wanted to implement some QOS on my Linux Box with HTB, but after some time
spend
on the configuration and tests, I still don''t manage to have some correct
results. Here are the details :
-ROOT 2000 kbits
-HIGHPRIO SUBCLASS 50 kbits prio 0
-SUBCLASS1 750 kbits prio 1
-SERVICE1 250 kbits prio 1

More on qdiscs
I notice one other small problem with my modified version of SFQ.
The fact that packets can be dropped at dequeue time is incompatible
with the way HTB (and probably CBQ and others modeled on it) keep
statistics. When I fill a low rate queue causing packets to expire
and be dropped at dequeue I get interesting statistics like this:
This is my variant of SFQ

Pfifo_fast "Unknown qdisc" and asking for basic design advice
Hi all,
I''ve done a search through the archives but I can''t find a
cause/solution to this.
I''m running a FC4 box with the stock 2.6.12 kernel and a FC2 box with a
stock 2.6.9 kernel. I''m obviously using
iproute2 and the patched tc.
When I clear down the qdiscs with "tc qdisc del dev <DEV> root" I get

tc u32 match !port
How can i redirect all traffic that not come from port 80 to a flow ?
i was thing about some like

But this not work.
Another doubt, if i have two rules that intersects , for example ,
one filter with u32 match ip src 10.10.10.10 flowid 1:10
and other with u32 match sport 80 0xffff flowid 1:11 , which one will

HTB - prio and rate
Hi all,
I''ve not been able to find an explanation of the relationship between
prio and rate as they apply to the HTB technique. Hopefully someone on
here will be able to help me.
As I understand things, when prio values are assigned to an HTB setup,
classes with a given prio value will only be serviced when there are no
packets waiting in classes with a lower prio value.
Now, does

Patch to allow for the ATM "cell tax"
I have been trying to optimise my ADSL connections for VOIP.
Funny things were happening - for example increasing the ping
packet size by 50% had no effect, but then adding one byte
had a major effect. It took me a while to figure out that I
was seeing the effects of the fixed ATM cell size.
This is probably obvious to some of you. For the rest: ADSL
uses ATM as its transport. An ATM

why isn''t 1:1 getting the traffic? [filter question]
With the below script, whenever I ping 10.0.16.10 (which matches the
only filter I have), traffic still get''s sent to the default 1:2 class
instead of 1:1 and I don''t know why... Any hints?

HTB and tc filter
Help me ...
I try use the tc filter, but seems he doesn''t work, I already
reconfigured my kernel ( 2.4.32 ) with all options related a QOS

eth0 is my internal NIC.

Hello.
I have a linux server connected to a gigabit lan, and though that lan to a

tc not matching
Dear all,
I''m having real problems getting tc to do anything useful at all. I''m
also under pressure to get this fixed before the students start arriving
later this month (I work in a university).
In short, I want each IP address to be hard limited to 128kbit down,
64kbit up, never to be allowed more bandwidth than this. It is also
important that the latency remains

PRIO inside HTB - trouble attaching filters correctly?
Hello everyone!
I''m simply trying to put a PRIO inside an HTB (used to throttle). I''ve got
interactive traffic on the network that I want to give priority (VoIP +
Citrix + Video).
I''ve used the filters in a CBQ script fine, but am having trouble
adjusting them to this setup such that they properly assign the traffic.
