[LARTC] share bandwith fairly

Dear members,

  I am trying to share the bandwith for all users fairly. because some users heavily uses p2p programs and a few hosts consume most of bandwith.  when we limit each flow it does not work as one client has many connection at same time.

 Firstly I tried  to write a script that use 
the ipfm(which accounts traffic usage) logs as follow
.extract  ip addresses heavy bandwith users from log file
.create a new class with 128kbit for that  Ip address 
. add tc filter for that IP by classify the ip addres with 'match ip dst' parameter.

it works for a few IP. After 4 or 5 ip addresses added it does not work for last added ip addresses.

let me show the lines that I used.

—------- creation of qdisc and parent —------------
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 12
tc class add dev eth0 parent 1 classid 1:1 htb rate 10mbit ceil 10mbit


—----works for each IP address found in ipfm logs that exceed the desired bandwith usage —---
 tc class add dev eth0 parent 1:1 classid 1:$index htb rate 128kbit ceil 128kbit
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 \match ip dst $ipaddress classid 1:$index

but it does not work good. then I tried to find better solution in maillist. there are some solutions there. but not appropriate to us as they required patching kernel like esfq,routehat,wrr.

 
is there any suggestion.

Thanks 
Note: sorry for my poor english.

Ideal for this situation is WRR ( http://wipl-wrr.sourceforge.net/wrr.html ). If
you are looking for an integrated solution, see my signature.

Thank you for your answer. I donwloaded shurdix and tried to install it. but it is really not user friendly. it was difficult for me to install it. after isnatallation i saw that all files are read only.
I change the rights but  I still couldnt edit the files. also I have many scripts run on my box. 
so it is not easy for me to change the system. also as I said I dont want to patch kernel and recompile it. I checked forum for shurdic there isnt any support in english.
 
system is as following.

 2.6.9-1.667smp #1 SMP Tue Nov 2 14:59:52 EST 2004 i686 i686 i386 GNU/Linux
use only one network device. 


I saw tc.sh script. As i see it is not applicabe to unpatched kernels like mine .
