I still have a very hard time figuring out your configuration. Please list
the following:

	* your iptables commands
	* your tc qdisc add commands
	* your tc class add commands
	* what kind of traffic you are generating

Thanks.

Now, I know the where the problem is.
If I already use SNAT, how could I limit the inbound bandwidth of 
Every intra-network ip protected by SNAT( with the help of iptables
nfmark)?
But mangle at PREROUTING goes before NAT translate. 
Is  there any method?

RE: [LARTC] HTB problem

[yangrunhua]

I could manage it now, modified the netfilter src, add another table not
mangle,
Which runs after NAT_SRC. :-)
Another problem: We know HTB is a tree structure, does it permit to jump
to the 
leaf directly?(I use cls_fw which attached to the root, and with no
options, so cls_fw would use nfmark of skb as classid and jump directly
into leaf, no traverse)

but when I use these:
tc qdisc add dev eth0 root handle 1: htb default 12
tc class add dev eth0 parent 1: classid 1:1 htb rate 100kbps ceil
100kbps burst 2k
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 30kbps ceil
100kbps burst 2k
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 10kbps ceil
100kbps burst 2k
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 60kbps ceil
100kbps burst 2k
tc filter add dev eth0 protocol ip fw

that, packets marked with 0x1000a don't jump into 1:10, why?
But when I use these:
tc qdisc add dev eth0 root handle 1: htb default 2
tc class add dev eth0 parent 1: classid 1:1 htb rate 5kbps ceil 5kbps
burst 2k
tc class add dev eth0 parent 1: classid 1:2 htb rate 10kbps ceil 10kbps
burst 2k
tc filter add dev eth0 protocol ip fw

in this situation, packets marked with 0x10001 succeeded in jumping into
1:1.

Why?

try replace 0x0001000a by 0x00010010. IIRC in 1:10
the "10" is in hex.

RE: [LARTC] HTB problem

[yangrunhua]

Thanks to everyone, my problem has been solved.
Here is my description:
for BIG ISP, if you have broadband for every client and use NAT_SRC to
let them out, and you want to divide bandwidth among all clients. My
solution is iproute2 + netfilter.
I've modified netfilter framework's src to hash every client (not like
originally,line by line) and also do some accounting based on flow, and
add a table(which hacks after NAT_SRC, not like mangle. Mangle hacks
before NAT_SRC), then mark the packets with it's classid related with
it's intra-network ipaddr, so the dev attached with filter fw with no
option will classify directly into the class with that classid, finally
control it's bandwidth(I use HTB).
Every step is O(1) in complexity. Excellent!
Thanks for all. Thanks for all the people here and from netfilter
mail-list.
Iproute2+ netfilter seems pretty good! I've got good performance!
I'm a new here, so very nice to hear from you, you are so kind.

[LARTC] htb problem

[Omar Armas]

[-- Attachment #1: Type: text/plain, Size: 1033 bytes --]


I have a doubt. What's the correct use of mangle for the next network:

eth0: 200.39.190.249 (public)
eth1: 192.168.101.254 (private)

I make nat with iptables and have the following htb script:

tc qdisc add dev eth1 root handle 1: htb default 30
tc class add dev eth1 parent 1: classid 1:1 htb rate 10mbit burst 15k
tc class add dev eth1 parent 1:1 classid 1:10 htb rate 15kbit ceil
10mbit burst 15k
tc filter add dev eth1 protocol ip parent 1:0 prio 1 handle 1 fw classid
1:10

(did the same rules for eth0), htb2, kernel 2.4.18
next mangle:

 iptables -I PREROUTING -t mangle -i eth1 -j MARK --set-mark 1


Well, I've spent hours changing values to mangle: PREROUTING, FORWARD,
POSTROUTING, etc.

But I can't make it work. I want that  all packets marked as "1" be
limited to 15kb.

Is it a mangle or script problem?
What would be the correct mangle rule?

Thanks,

You have inproper ceil rate pointing to 10mbit. Dont touch ceil parameter
or setup it at 15kbit value not 10mbit ;)

 I am shaping traffic for ~250 users and i have noticed something is wrong:

 When i run the script which creates the classes the following error is printed to syslog:

... etc etc.

I searched google and found some posts on this error, they said to change the r1q quantum 
value, tho it wasnt clearly said how big the value should be.

Could anyone tell me what r2q value to set if thaffic is shaped to 32kbit, 64 kbit and 128kbit/s?

I read the manual of HTB and it says:
'Normaly you don't need to specify quantums manualy as HTB chooses precomputed values. It 
computes classe's quantum (when you add or change it) as its rate divided by r2q global 
parameter. Its default value is 10 and because typical MTU is 1500 the default is good for rates 
from 15 kBps (120 kbit). For smaller minimal rates specify r2q 1 when creating qdisc - it is good 
from 12 kbit which should be enough'

So, is 
'r2q 3' enough for 32kbit/s
'r2q 6' enough for 64kbit/s
and
'r2q 10' (default) enough for 128kbit/s+?


Soon after the 'HTB: quantum of class <class> is small' messages in syslog i get the following 
errors from HTB:
(around 10 minutes after the warnings of 'quantum of class <class> is small':

Dec  9 20:04:43 p1 kernel: HTB: bad diff in events, cl\x10345 diffFCE0000 now\x1187872768

thenB94909952 j\x10107481

And it seems the classes start dying one after other, cause the clients start calling me and 
screaming 'internet doesnt work'.
as soon as i flush qdisc, everything works perfect again.
So for now i have put the traffic script in crontab flushing and adding classes every 15 minutes.

Any suggestions?

I am using HTB 3.6 and Linux 2.4.19

I tried Linux 2.4.20 with HTB included, tho the results were much more poor - if i shaped traffic 
to 256kbit/s on 2.4.19 the ping was around 200ms (constant), tho on 2.4.20 it was increasing 
and decreasing dramatically - from 6000ms to 80ms.

Quantum = rate / r2q.  Quantum should be > 1500 and smaller then 60.000.
I have some more info on www.docum.org on the faq page.

2.4.20 has htb 3.6.  So it's the same version.  It's strange that you have 
different results.

[LARTC] HTB problem

[Jay Wineinger]

Hi,
    Ive been looking at tinkering with the linux traffic control stuff
lately and decided to try out the htb qdisc.  My setup is as follows:

2 interfaces: eth0 goes to internet, and eth1 goes to a NAT'd subnet. eth0
has a 7mbit link, but only a 4.5 mbit link to the internet while eth1 is a
100 mbit link to the internal subnet.  The box that is doing the routing
(and tc soon, hopefully) acts as webserver,dhcp,firewall,NAT,and fileserver
for the internal subnet.  The internal network (at a college) has heavy
kazaa and other filesharing usage over the internet.   I want to use the
lartc utilities to make the bulk traffic from filesharing,etc to be the
lowest priority and have interactive (ssh), mail, and http be higher prios
(in that order).

Anyway, I dont want to limit the traffic that is going TO the server only,
ie. people taking files off my server, and I dont really care who is
creating the traffic, I just want priorities  on types of traffic.  That
being the case, I decided to do the shaping on the eth0 interface.  Ive
setup rules in iptables to mark the different kinds of traffic.

With that done, I created the root htb qdisc  with the following:
    $TC qdisc add dev eth0 root handle 1: htb default 20

However, I get an error about illegal rate when I try to create a class
with:
    $TC class add dev eth0 parent 1:1 classid 1:10 htb rate 30kpbs burst 2k
prio 1 ceil 100kbps

I wondered if my tc version wasnt up-to date enough to work with htb, but it
was the one downloaded from the htb homepage at
http://luxik.cdi.cz/~devik/qos/htb/v3/htb3.6-020525.tgz

# ./tc -V
tc utility, iproute2-ss991023

is there anything else that might need updating, or is my syntax wrong?  any
suggestions about my setup would be welcome as well, since this is my first
attempt at this

thanks,
jay

[mingching.tiew]

You have a typo :-  kpbs

Also, it seems that the parent 1:1 is not created yet.

[LARTC] htb problem

[Ratel]

Hi,

I have some interesting problem with htb , I set up root class and
sub-classess:

$TC qdisc add dev eth0 root handle 1: htb
$TC class add dev eth0 parent 1: classid 1:1 htb rate 1990kbit ceil 2000kbit
$TC class add dev eth0 parent 1:1 classid 1:10 htb rate 190kbit ceil 200kbit
$TC class add dev eth0 parent 1:1 classid 1:11 htb rate 1400kbit ceil
1600kbit
$TC class add dev eth0 parent 1:1 classid 1:12 htb rate 1000kbit ceil
1500kbit
$TC class add dev eth0 parent 1:1 classid 1:13 htb rate 1000kbit ceil
1500kbit
$TC class add dev eth0 parent 1:1 classid 1:14 htb rate 1000kbit ceil
1200kbit

, filters and queuing disciplines :
#filter
$TC filter add dev eth0 protocol ip parent 1:0 prio 1 handle 2 fw flowid
1:10 classid 1:10
$TC filter add dev eth0 protocol ip parent 1:0 prio 1 handle 3 fw flowid

1:13 classid 1:13
$TC filter add dev eth0 protocol ip parent 1:0 prio 1 handle 6 fw flowid

(note the packet marking classifier)

adequate lines from firewall script :

Re: [LARTC] htb problem

[Esteban]

do you have two nics? the 2megas internet is eth0 right? so you are tc'ing packets going out of interface eth0.

paquets are comming from eth1 for example? 
in such case you coutlf -t mangle -I PREROUTING -i eth1 -j MARK --set-mark {1|2|4|}
??

so packets going from internal (eth1) going out (eth0) are previusly marked.
im pretty sure about this.
hope it helps, good luck.

The sum of the rates of the childs should be <= rate of parent.  In your case 
1400 + 1000 + 1000 + 1000 = 4400 and your parent rate is 1990.  It's not 
needed, but I recommend it.

And I also note the different prios.  That's not needed.  Prio determines the 
order the filters are checked.  In your case it doesn't matter.

Mhh.  Can you check with iptables -L -v -n that your packets are marked?  And 
can you tell us what's your setup ?  I mean wich nic is connected to the 
internet, what do you want to shape, is this also a firewall?  And try 
marking in the PREROUTING tables.

I have the same problem. According to iptables the packets are marked but
all the traffic goes to the root htb class.

Mhh.  Some commands that works for me :

tc filter add dev eth0 parent 1: protocol ip handle 1 fw classid 1:100
iptables -A OUTPUT -t mangle -p tcp --dport 2000 -j MARK --set-mark 1

So your filters are working.  The lended packets are not important.
For your htb setup, have you read the docs I collected on www.docum.org ?

Remove burst and prio parameter from your commands.  And make sure the sum of 
child rates <= parent rate.  In your case 512 + 50 >> 512.
And all non-classified packets have to go somewhere.  This can be done with 
the default parameter if you add the htb root disc or a catch all filter 
rule.

Hey I hve the same problem. My packets are marked, my classes are OK
my filters are set OK

Ok.  I don't understand.  I do all my test using iptables and fw filter.  This 
works for me :
tc filter add dev eth0 parent 1: protocol ip handle 1 fw classid 1:100
iptables -A OUTPUT -t mangle -p tcp --dport 2000 -j MARK --set-mark 1

This is on a simple pc.  No router, no bridge, no firewall.  It's only used to 
shape outgoing locally bandwidth.

Re: [LARTC] htb problem

[Ratel]

Thx a lot for help , I finally managed to rebuild my firewall script,

for people who have same problem as I had, I can say that
the problem lies in propper packet marking (iptables) , sample lines from my
firewall script :

iptables -t mangle -I PREROUTING -i eth0 -p tcp --dport 21 -j
MARK --set-mark 2
iptables -t mangle -I PREROUTING -i eth0 -p tcp --dport 443 -j
MARK --set-mark 3

it's ofcourse not the only way to mark them,
http://www.docum.org/stef.coene/qos/kptd/ is very useful with that.

[LARTC] htb problem

[Delcho]

Hello,
I have a problem with my htb in linux gateway machine.
Wana make this borrow to and from internet:
every user must be shaped to 32Kbit,max number of users are 6 in one 
subnet /29
and all subnet must be shaped to 92Kbit,e.i every user  will download 
with 32Kbit,but when
all 6 user download do not over 92Kbit! I make some classes /attache 
them/ but every user download with 32Kbit and over many up 92Kbit.
The script:
 
tc qdisc add dev eth1 root handle 1: htb default 2
 tc class add dev eth1 parent 1: classid 1:2 htb rate 100Mbit
ceil 100Mbit burst 1k
 tc class add dev eth1 parent 1:2 classid 1:11 htb rate
92Kbit ceil 92Kbit burst 1k
tc qdisc add dev eth1 parent 1:11 handle 11 sfq perturb 10
 tc class add dev eth1 parent 1:11 classid 1:30 htb rate
32Kbit ceil 32Kbit burst 1k
tc qdisc add dev eth1 parent 1:30 handle 30 sfq perturb 10

 tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32
match ip dst 192.168.1.22 classid 1:80

May be there is mistake but where.....?

Take a look at the faq pages on docum.org.  There is a section with htb rules.  
The problem is that the rate is a minium and the parent ceil is not respected 
if the child classes are asking more then the ceil.

Yes and no.
I think you are using htb.init and this is not the htb.init mailing list.

[LARTC] HTB problem

[Mihai Tanasescu]

Hello,

I'm having some problems using HTB to prioritize traffic on my linux router.
The main problem is as follows:
I have a 6Mbits channel on the metropolitan network and a 64kbps link 
for the sites outside my country.

These 64kbps are dynamically allocated by my ISP so I usually get 
something like 128kbps , sometimes 512kbps and even 1 Mbit; it varies 
all the time.

Because of this I don't know how to automatically adjust my HTB script 
depending on the total bandwidth available on the external link (without 
specifying the maximum to 64kbps thus limitting every connection even if 
my ISP grants me more than this bandwidth).

Anyone got any ideas ?

You cannot have a variable bandwidth with htb.
Count on the minimum bandwidth.

[LARTC] HTB problem...

[Cow]

Hi folks.

Let's say I would like to make some bandwidth control on my network
using HTB. I have 2 clients:

PC1: 192.168.100.2
PC2: 192.168.100.3

Server:
192.168.100.1
This has 2 NIC's eth1 is local and eth2 is connected to the internet.

It could be nice to have a script, where you could specify, how much
bandwidth you want for a specific host on a network, like, PC1 has
10/100 MBit network, but only has 256/128, when surfing the net. PC2 has
the same network ofc, but 768/384 when surfing/downloading assuming the
shared connection is 1024/512.

I am currently running wondershaper1.1a which works prefectly, but i
wish, it could be more specific.
Could also be nice, if it would be someway possible to check on the
clients IP or MAC address to verify, if it's "really them". Like it's
only PC1 and PC2 who have access to the server in the 192.168.*.*
segment. Hope i make myself clear.

My server runs redhat 9 in cmd mode/no GUI.
Iptables installed script, as firewall.

I think a script as i described, could be very complex to write,
therefore i ask, whoever is here, for help.
Thank you all in advance.

Regards
Rune Johannesen
Denmark

Hello all, my first post here, maybe even I will help someone;)

I assume that you want somethink like:
data from server to LAN (PC1,PC2) unshaped (full 100mbit)
data from Internet to LAN shaped

Then all you need to do is make classes with source 192.168.0.1 and 
destination 192.168.0.2(3) and 100mbit rate and then make classes with 
destination 192.168.0.2(3) with download rate. I believe that you understand 
what I am thinkig of.

Or you can use iptables and mark traffic going from server to LAN, and other 
mark for traffic in FORWARD chain. (iptables -t mangle -A FORWARD -j MARK 
--set-mark SOME_MARK)
When using iptables you will be able to shape upload speed, just mark traffic 
in forward going from PC1/2 with output interface eth2 (-o eth2) - it will be 
hosts upload.

I won't write you full script, make it yourself, visit LARTC and firstly try 
"htb.init" for simple class creation. Good fun!

Not tested yet...
If it works, feel free to letting me know, how to make something like
this, just for download rate.
If it doesn't work, please let me know, what you think is wrong.

Looks nice, want to share the bug with me? :-)

Correct.

I do, but could you write an example please, so i have something to make
it from? :-)

Again, an example would be nice.. i have no idea on how to use MARK
command with iptables, even i know a great deal about iptables in
general.

Fair enough, i wouldn't exspect anyone to write a full script for me,
but i would exspect someone to make me an example for instance, how i
can shape PC1's download/upload rate to 256/128 KBit, so i atleast have
something to help me going.

Not really an example, but you may have a look at my script [1].

It solves the 100Mbit LAN vs internet traffic by using a class setup which 
looks like [2], which reminds me that I did a modification to wondershaper 
once [3] that does the same. I think this modification was reported to 
work, however I haven't tested it nor do I support it. Maybe it serves as 
an example...

I'm using a fat HTB class which knows the true interface bandwidth (100MBit 
isn't actually right, you should measure what rates you really get). Then 
there's a child class for the internet traffic and one for the actual LAN 
traffic. If HTB works correctly, this way you get full speed for LAN-only 
transfers, without letting them interfere with the internet traffic.

The script [1] is the one I'm (more or less) actively working on; it 
doesn't support custom rates per user yet, but that's something that'll be 
added for sure in one of the next releases.
