If a (c)bursts causes a class to exceed it's configured rate it will take some time (that many pseudo microseconds) for the rate to drop back to the configured rate. Right?

[LARTC] Re: HTB
Hi, What exactly happens if the sum of the children classes rate is bigger than the parent's? I would say that in most cases it would be a misconfiguration, especially if you have more layers of HTB classes. The bw you configure with rate is not going to be reserved properly if you do not respect the rule rate(parent)=Sum of rates(children). Anyway, the parent node does not throttle the children classes. Parents are there mainly to allow borrowing and sharing between sibling/descendant classes. What if the majority of these classes are using less than the minimum rate established (eg. 0kbps)? Why should this be a problem? In this case a class simply uses less than what it has been allocated. Depending on your configuration, other classes would probably be able to borrow more.

I was not aware that segmentation offloading would cause a problem... and I do believe it's on. I think I'll just stuck with the high mtu for the moment then, as I would rather have the CPU savings then more accurate traffic controlling.

I solved my problem by myself, by studying devik's HTB manual: http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm Here are my remarks for those browsing the mailing list archive. The line that made me realize what I was doing wrong is: The rate supplied for a parent should be the sum of the rates of its children. Apparently I was confusing the purpose of 'rate' to that of 'ceil' and HTB was not too happy about it.

It seems i resolved my problem - there is no connection loss while reseting htb, but I'll be observing it's stability in a few days. I have no words to write what a STUPID mistake it was. As i suposed it was conected with packet marking.

Hello everybody!
Since week i dig lists and www and can't find solution for my
problem.
I'm using HTB 3.13 kernel 2-4-25 smp iptables 1.2.9.
I've got situation like this:
LAN--Linux Box(routing only)--- Linux Box
(HTB)--Hardware Router(say:HD)--Internet
When I start HTB it takes about 5 min. to start working and it
works...
within this 5min starting i can't ping HD and after about 5min I
start
pinging. It works like this for cuple of hours, then something
strange
is
happening. Ping stops, www doesn't work but radio (36kbps) (from
clients)
works. There is no ping at all for about 1min and it starts
pinging
for
about 2-3min and it stops for 1-2min and so on.
When I stop HTB
Re: [LARTC] Re: HTB 3.13 please help
as you can see, NO packets are going thru. You have to look
to other classes as well as to ifconfig and tc -s qdisc show dev xxx

Hello everybody!
Since week i dig lists and www and can't find solution for my
problem.
I'm using HTB 3.13 kernel 2-4-25 smp iptables 1.2.9.
I've got situation like this:
LAN--Linux Box(routing only)--- Linux Box

When I start HTB it takes about 5 min. to start working and it
works...
within this 5min starting i can't ping HD and after about 5min I
Re: [LARTC] Re: HTB 3.13 please help
oops. I took bad classes (these clients where down so there was no traffic )
lately from tc -s -d class show dev eth0.
These are classes (part of) while there was no connection from clients.
BTW is it good tcng config with fw. I mean if
fw {
class $classname on (2);
}
means match packet to $classname if it's mark equals 2 ?
Is there any kind of sniffer or smth like that for tc? I mean to look in
realtime packet statistics. Smthing like iptraf maybe?

as you can see, NO packets are going thru. You have to look
to other classes as well as to ifconfig and tc -s qdisc show dev xxx
to see wherw packets are lost.

//Just to not forget eth0 is WAN and eth1 is LAN . The box is NATing my

I configured tcng to shape both download and upload

Maybe it is my script fault or it is something bad with packets marking
.
this is how i mark outgoing packets
iptables -t mangle -A MYSHAPER-OUT -p tcp -s 192.168.1.23 -j
MARK --set-mark
$ip
and this part of my script which is intented to shape upload:
dev eth0 {
egress {

htb ( r2q 1 ) {

that is interesting. let me know then. other test might be to
reboot with maxcpus=1 to mitigate smp related bugs.

From the stats is seems that no data are queued - as if nobody
is sending them. You are using smp kernel, is your box SMP ?
I haven't seen many smp+htb boxes thus there might be possibility
of a bug...

[LARTC] Re: HTB
I have a fiber connection to MAN1, an ethernet connection to MAN2 (another city), and an ethernet connection to the WAN. My question was (well actually my new question is...) if i can shape all of the traffic using a computer with 4 nics (2xMAN,1 WAN,1 LAN) and what delays will this introduce (if it works)? Can a nic be part of multiple bridges If yes how will this affect my marking of the packets???

Re: [LARTC] Re: HTB and metro+int. limits
I'm sorry, but I'm still confused about assigning separate limits for metro and international traffic. After I mark metro traffic with --set-mark 6 and int. traffic with --set-mark 5 what's the next step? Can someone give me an example? It seems that my approach is somehow wrong after marking of the packets. Thanks again.

Anything else /sbin/iptables -t mangle -A PREROUTING -i eth2 -d 0/0 -j MARK --set-mark 5 /snip This will not differentiate your traffic. Everything -i eth2 will end up marked '5' because iptables will evaluate against every rule in order, eventually marking them '5' whether they have previously been marked '6' or not. You need to create a new table with two commands for each address range. ie: /sbin/iptables -t mangle -N MYMARKER /sbin/iptables -t mangle -A PREROUTING -i eth2 -j MYMARKER # and ... /sbin/iptables -t mangle -A MYMARKER -d 193.231.15.0/24 -j MARK --set-mark 6 /sbin/iptables -t mangle -A MYMARKER -d 193.231.15.0/24 -j RETURN # for each metro range, and finally /sbin/iptables -t mangle -A MYMARKER -j MARK --set-mark 5 /sbin/iptables -t mangle -A MYMARKER -j RETURN The separate table and the 'RETURN' statements give you the short-circuit evaluation you require. BTW: You might be able to consolidate your metro class-C's into fewer (larger) CIDR ranges to speed evaluation.

If a packet is enqueued in the htb qdisc, all filters attached to the root qdisc are checked. If a packet is redirected to a leaf class, it's dequeued in the qdisc attached to the class. If a packet is redirected to a class, the filters attached to that class are examined. In previously htb versions, htb hangs if you redirect a packet to a non-leaf class. That's solved in later versions.

[LARTC] Re: HTB code :-)
As I understand, in HTB you are able to map traffic to a queue named direct_queue. This queue is initialized in function htb_init(), and is a qdisc not a class, is this right?? it is class with implicitly attached queue Another question of interest is how can I use it. Is this queue associated to the queue with highest prio? And how is this done?? this queue is used when you explicitly direct data to X:0 class (by filter) or when used in default 0. devik ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

[LARTC] Re: htb
Ok here is solution. 1) the filter is not swallowed. For inner filters you have to use tc filter show dev lo parent 1:1. If you miss parent keyword nothing will be shown. 2) the code you attached can't work. You wanted to use default keyword to direct packets into 1:1 and then use filter attached to 1:1. It can't be done. default is resolved as last instance and MUST point to a LEAF. No other resolution is done then. To solve your prob use catchall u32 filter (src 0.0.0.0 0 f.e.). on 1: and flowid 1:1. devik On Mon, 1 Jul 2002, Oswald Buddenhagen wrote: On Mon, Jul 01, 2002 at 04:46:12PM +0200, Martin Devera wrote: probably I can. but you have to create test case as simple as possible. it can't get simpler than the attached, i guess ... :) as opposed to my previous observations, filters attached to classes of of the root qdisc are swallowed as well (that means, they don't even show up in tc filter show dev eth0).
