[LARTC] Strange HTB problem

[Venceslav Vatashki]

Hello friends,
I have small LAN network with 5 computers.I use HTB init script
with configuration like this :
//////
RATEЂKbit
PRIO=5
LEAF=sfq
RULE\x192.168.1.[1..6]
//////
The problem is when user start to download with Flashget,MassDownloader
(with 10 threads) he kills the internet connection (240Kbit) without 
overlimiting his 80Kbit. Other users get 1-2kbps, witch is extremely 
unpleasant.

Btw which is the HTB version that ships with linux 2.4.20 ?
Thank you

So you have 240Kbit, 1 user uses his 80kbit and other users don't get any 
bandwidth.  Are all these users in the same class?  If they are, it's the sfq 
qdisc that causes problems.  
It will create 1 "queue" for each flow.  Flows have different ip-addresses and 
ports.  So the 10 downloads ends up in 10 different queues.  So the more 
sessions a user opens, the more bandwidth he gets
You can try the esfq qdisc.  That's an enhanced sfq qdisc.  You can create the 
different queues based on ip-addresses and/or ports and this for source 
and/or destination.  In your case, you can use the source address so each 
user has his own queue. So each user has the same amount of bandwidth.  I 
have a link somewhere on the faq page on www.docum.org.

I think it's 3.7 but it's the same code as version 3.6.
