[LARTC] htb

[LARTC] htb

[George Tsuladze]

How can i do the following: i have 100 kb leased line. I have 2 ips in 
my network 1) 1.2.3.1 2) 1.2.3.2 , i gave all of them 100 kbps, but if 
1.2.3.1 needs 80 kb, and 1.2.3.2 downlloads with 90, 1.2.3.1 must get 80 
kb, and 1.2.3.2 continue download with 10 kbps.

Re: [LARTC] htb

[Soulfly]

If 1.2.3.1 is absolute priority you should use the prio qdisc and put in a
filter that brings 1.2.3.1's traffic to a band with higher priority (read
the LARTC HOWTO in http://lartc.org/ ).  If you want to give 1.2.3.2 minimum
bandwidth to use (like 10 kbps) then I recommend HTB (
http://luxik.cdi.cz/~devik/qos/htb/ ) but you must patch both kernel and tc.

In either case or if you decide to use anything else you should understand
the problem domain. Start with readning LARTC-HOWTO.

You can use it in stead of CBQ to manage the available bandwidth.  You can 
create a setup where hosts/services/traffic-flows can borrow bandwidth from 
each other and where you can specify minimum bandwidths

patching? :)

If you wanna try 3.6 code, download the tgz, untargzip it (tar xzpf) and 
you'll see a diff/patch. Just "patch -p1 --dry-run < patchname" and see if it 
succeed, if, leave out --dry-run, if not, fix the errors. If you have 
questions when errors occur, don't hesitate to ask.

for HTB2 code, just download the patch and follow the same as above (patch -p1 
...)

Compile kernel 2.4.20 with HTB support.


Or else get kernel patches for 2.4.x (or 2.2.x) from devik's homepage.

I tried the "patch -p1 --dry-run ./htb3.6_2.4.17.diff" but nothing happened,
no error message, nothing.

That's why I've said "compile" and not "patch". :-)

Nop.  You have to choose "n".  Some general clean-up patches that are in the 
htb patch are already applied to the defaul tkernel.

Re: [LARTC] HTB

[Chandrashekhar Rane]

Dear Rimas,

I think you trying to remove any qdisc already present on your egress
queue.

If you have not created any qdisc before trying to remove it, then
defn't it will give such error.  

You need to redirect it to /dev/null. if you trying to do the same
before creating the root qdisc.

Running HTB on leaf bearing 1.0-stable with kernel 2.4.20

Hi!
  Can somebody explain what is wrong from the above?
I can't understand following relation:
"rate 48Mbit ceil 48Mbit" and "rate 730783bps 570pps backlog 112p"
Why the current rate is limited to 730KByte/s (and there is backlog
112p) when the rate and ceil are 48Mbit/s (6Mbyte/s)?
I sent similar question some months ago, but there was no answer.

rate 730783bps means that the average rate is 730783bps for that class.  And 
570pps means that class sends 570 packets per seconds.  So it's just some 
statistics for that class.
I'm not sure for the backlog, but I think it means that there are 112 packets 
in the queue ready to be send.

Satisfied :)
But partially :(
The problem is that the bandwidth is REALLY limited to about 730kbps.
And isn't the backlog the number of packets, delayed due to bandwidth reached
the shaper limit?

Then your class reaches it's limit.  But why do you have a ceil of 48Mbps and 
730kbps?

> reached the shaper limit?
Or like I said, there are packets in the queue ready to be send but they can't 
due to limited link bandwidth.

Exactly. Why?
I can't find out.

What's the command you used to create that class?

Your burst is too low.  If you don't specify it, htb will calculate the 
minimum burst for you.

[LARTC] HTB

[Cristea Virgil Ionut]

Hi, I have the following questions:

I only have one htb computer (2 nics) to shape the international traffic 
as well as the metropolitan traffic (i have a list of metropolitan ip's to 
use). Can this be achived using iptables with packet marking (on that htb 
computer the 2 nics are bridged)?
If it can will there be delays introduced by the shaping operation (the 
metropolitan link is a 100M fiber - full almost all the time)???

Re: [LARTC] HTB

[Andre Correa]

Cristea, you are too vague in your question. I can tell you that you can 
shape MAN and WAN traffic separately using diferent classes and filters.

100Mbits for a single machine looks like too much traffic. Maybe you 
should divide load between more machines and have redundancy in your setup.

If this is not what you meant, please let us know...

Andre

[LARTC] HTB

[Arturas Lapiene]

Hello,

I have problems with htb. The problem is that when I download
any file via shaper with htb, the traffic is very dinamic, 
it jumps, for example:
if i have set ceil = 128kbit the results that it jumps from 112kbps
to 144kbps or smth like that maybe its not very bad, but when the
traffic drops down to 40kbps or less and then after 1 or 2 seconds
jumps to 144kbps, its bad :-( and it is often.

Root class is 20Mbit
There are about 7000 classes (on two interfaces)

an example script:

Hi all

I'm new in this list and i hope to lear and to help if possible.

But firt i need help :-(

I used to have an Oops an awful lot like that.  I upgraded to 2.6.9-rc3 and it 
resolved the problem.  Yours could be something else, though.

What `tc` configuration are you using?  What's the simplest possible 
configuration you can create that consistently reproduces the problem?

What specifically did you do to trigger this problem, if you know?

Thanks.

[LARTC] htb

[James Lista]

[-- Attachment #1: Type: text/plain, Size: 1030 bytes --]

buddies,

i am newbie to band control..  i have a linux box (as a router, NATing,) sharing internet

----internet----------eth0-[linux.box]-eth1----------my.lan
              
wan = adsl 600
lan  = about 20 users

my problem is that due the contract i cannot block users from my lan from downloading anything, so they can use kazaa (argghh), edonkey(argghhhhh), emule(arghhhhhh), soulseek(arghjhhhh) etc etc etc,     

so,

I want to know if using htb i can make that users that uses browsers (port 80) have priority then users that uses port (110 and 25) , then rest of the ports.....    as if i could have such thing:


600kbit --------   50% for port 80
                       30% for port 25 and 110
                       20% for the rest 

this way no user can complain that cannot access his internet banking, checking his emails  and other thing that are essentials...

if it is possible (with htb) or any other method, please tell me a direction for me to go..

really thanks

james

do you have a small script example to show me ? ...  i am new to those thing.. wanna study examples to understand how things works...   tried reading some docs but my english is poor so, i could understand very few..

  This is no good cause for example bittorent can download on port 80 :D. So the best way is create classes with ceil parameter for example 128kbit to ensure relability for every user and limit number of connections to 50-80 per user. This the best (i can get a word grr....- you know) if you dont want to block p2p.

Sure, that's possible. That's one 600kbit class with three child classes.

However, there may be many other ports besides 25, 80, and 110 that deserve 
prioritizing. Throwing them in the same class as all filesharing traffic 
could make things even worse than before.

Then there's the problem that many filesharing protocols can work on any 
port, so your users could just move to one of the prioritized ports and 
take all the bandwidth again.

That's some of the reasons why I never bothered with prioritizing ports on 
a global basis. Consider using ipp2p or l7-filter for a more reliable way 
for detecting P2P traffic.

No matter how you look at it, 600kbit for 20 users is a bit slow. Even 
without P2P traffic, if all of them surf the web at the same time, they 
won't be very happy with the speed. 

Besides traffic shaping, you should do anything possible to reduce load. 
Cache DNS queries, provide a HTTP proxy, probably squid. Make sure that 
you can't be flooded from the outside. Stuff like that.

Re: [LARTC] htb

[James Lista]

andreas,

having one class per user seems cool... please buddy, have a sample script
of that ?
so, if i have 600kbit / 7 = 86kbit for each, is it that ???  if so, is it
too few for a single user ?
about something that i read that say "borrowing",  when a user borrow his
spare band to a "vampire", when will he gets it back when he needs it...?

thanks again

Re: [LARTC] htb

andreas

first thanks for the answer and the advices.

well. let me say some things: inspite of saying that i have 600kbit for 20
users, it is really rare to have more than 7 at the same time

and about that you say take a look at ipp2p or l7-filter:  errr,  can they
identify when a user changed edonkey or any other p2p default port and limit
such packet even so ????

They try to. I'm using IPP2P and it works okay for me.

Although my shaping setup is a little different from what you want to do. 
I've got one class per user, so everyone gets the same share of bandwidth. 
This way it doesn't matter what kind of traffic a user generates, as it 
doesn't influence the others.

Prioritization is then done within the user classes, the only effect of 
that is that a user can still have a lag free SSH connection while he's 
downloading stuff at the same time.

So in my setup, if the user finds a way to trick the prioritization 
settings, he's only tricking himself, because he can't escape his user 
class :)

[LARTC] HTB

["Marcus Schäfer"]

 Hello folks, 
 
 I´m a fully Beginner in Linux and Traffic Control. 
 I have a lot of Problems to realize the following Scenario(I need it for my

 scholastics): 
  
 2 customers share one 2Mbit link. The packets of the customers are coming
on 
 the interface with a NAT Adress each. Each of the customers should use only

 1Mbit of the Line. 
  
          192.168.0.1        - - -  
          customer1    eth0 |     | eth1        customer1 
                 -----------|     |-------------- 
          customer2    2Mbit|     | 2Mbit       customer2 
          192.168.1.99       - - - 
  
 I think I have to use 2 Scripts, one for each interface (on every side). 
  
 I have written a small skript, but i´m unsteady if it works. It would be 
 very nice, if you can take a look at it and give me some hints. 
  
 Greetings  
 Marcus Schäfer

[LARTC] HTB

[Marco Aurelio]

What exactly happens if the sum of the children classes rate is bigger
than the parent's?

What if the majority of these classes are using less than the minimum
rate established (eg. 0kbps)?

HTB will assign to the leaf the rate regardeless of the value of the 
parent's rate.
The parent's rate is used only to compute how much bandwith must be 
allocated to the leaf's ceil.
