Testing system evironment...not working?

["wong cheongseng" <cheongseng@xxxxxxxxxxx>]

hey, i wrote the queue schedulling script for controlling the bandwidth use by FTP and HTTP.

I didnt get any error message when i execute the scrip.

But when i setup the LAN to test the Qos gateway.

The Qos gateway not fuctionning...

If anyone read this script, please info me where is the error. Thank you.

 

 

#!/bin/bash -x

DOWNLINK=80000

UPLINK=80000

DEV0="eth0"

DEV1="eth1"

if [ "$1" = "status" ]

then

tc -s qdisc ls dev $DEV0

tc -s class ls dev $DEV0

tc -s qdisc ls dev $DEV1

tc -s class ls dev $DEV1

exit

fi

#Remove all previous queues

echo "deleting..."

tc qdisc del dev $DEV0 root 2> /dev/null > /dev/null

tc qdisc del dev $DEV1 root 2> /dev/null > /dev/null

tc class del dev $DEV0 ingress 2> /dev/null > /dev/null

tc class del dev $DEV1 ingress 2> /dev/null > /dev/null

if [ "$1" = "stop" ]

then

exit

fi

#add the root

echo "adding..."

tc qdisc add dev $DEV0 root handle 1: htb default 30

tc qdisc add dev $DEV1 root handle 2: htb default 30

if [ "$1" = "stop" ]

then

exit

fi

#show the result

echo "the ftp use 30% bandwidth http use 70% "

 

 And the figure below is my testing eviroment.   

         PC1                                             PC2                                             PC3

         eth0                      &
 nbsp;       eth0                         eth1                             eth0

   192.168.1.0               192.168.1.245         192.168.2.245               192.168.2.0            

    FTP Server             Sub-network A    Sub-network B 
 ;      Client 

   Web-Server                                  Qos Tool                               
 ;Download tool         

FTP-Server = Bullet Proof FTP Server v2.21  

Web-Server = TOMCAT Apache

Download tool = Net Transfer

Qos tool = Qos Layer 7 Packet filter

                                The testing system environment

 Isnt possible i succes to control the transfer rate of the application??
