WampServer

Hello!

I use WAMP serwer on localhost (XP) to test web applications (offline).

Q: How I can slow down OR control bandwith/data transfer from/to (upload/downoad) to simulate normal activity of the user in the Internet. online?

For example user simulation download www site by: 128 Kbit/s, 256, 512, 1 Mbit etc?

It's possible?


Best regards,
Lech

mod_bw i think is the only way as mod_throttle is not available anymore

Hi, Steve

1.

Thank you for your response.

>mod_bw i think is the only way

Little comment: I'm beginner about servers. I'm rather Inventor/Java Script/Pascal/Neural Networks developer than Apache specjalist. I'm woring in Poland.

Can you explain in simply english more about "mod_bw"? What is it, How and where include this?

And any example about use it?

***

2. I'm also looking for a localhost-serwer AND/OR plugin AND/OR program to fluent control bandwidth (for example from 64 Kbit to 8 Mbit) by simple moving a slider on the screen or like this.

Just I'd like to test offline on my XP a photos downloading, www graphics elements, movies, the order and the time of starting the java scripts etc.

Thanx,
Lech

no this wont be possible...

the server will needed to be restarted to change the value..

possibly the value could be changed automatically depending on the load on the server ( how many people are connected etc)

but i dont think you could build a slider (esp without a deep understanding of apache modules)

i can only point you to the maker of mod_bw >> [bwmod.sourceforge.net]

Thank you again for the reponse.

To build a slider? Oh my Code, I'm not Apache programmer :-) What is the funny idea?

I know JS, PHP, Delphi, many of Basics languages, Motorola assembler, DSP audio processing...

Apart from that I can write music, I know a lot of problems from electronics, chemistry and physics. Whether now I am supposed to learn still to Apache programm on the low level? Oh no!

***

BTW: strange in the 21st century, in times of such wonderful tools, languages, editors, tools for programmers doesn't have something such obvious as the speed adjuster for www developers, that is acting simple like a washing machine. Without studying of the tons of books about Apache (sizes of the Bible).

Your link is very useful.

Thank you.
End for now,
See You Next Time
Lech

if you were not on windows... there is probably all the tools you need for apache..

unfornuatly Linux is still where the development time is put in from apache developers

Hello Steven again.

I'm runnig bw_mod, but this break the Apache.

My way:

Wamp

1. Load Wamp from: www.wampserver.com/en/download.php
2. Install on XP
3. Load added version of Wamp-Apache: downloads.sourceforge.net/wampserver/WampServer2-APACHE2214.exe?download
4. Install

Module

5. Load bw_mod for Apache version 2.2.14 from: [ivn.cl]
(main page is: [ivn.cl])
6. Copy dll to: modules/mod_bw.dll
7. Edit httpd.conf, and add this line:
LoadModule bw_module modules/mod_bw.dll
8. Run Wamp

Effect? Apache isn't starting.

***

But, if I add a comment:

#LoadModule bw_module modules/mod_bw.dll

then Apache run ok, but without the bandwith limitter.


So what I can to do?

Lech

Hello Steven

and thanx for your patience.


Steps:

1. Running Wamp: mydisc\wamp\wampmanager.exe
2. Try runnig command line.
On my XP this does not works (with SHIFT left or right is no command line)

So I run this by other way:

a) Open dos window
b) cd mydisc\wamp\bin\apache\Apache2.2.14\bin\
c) type:

httpd -t

It works.

Results:
-----------

This is result if Wamp start normal (for #LoadModule bw_module modules/mod_bw.dll):

=============
Syntax OK
=============

-----------

This is result if Wamp start and stop (for LoadModule bw_module modules/mod_bw.dll):

=============
Syntax error on line 129 of: mydisc/wamp/bin/apache/Apache2.2.14/conf/httpd.conf

LoadModule bw_module modules/mod_bw.dll

***

I try change line 129:

from:

LoadModule bw_module modules/mod_bw.dll

to:

LoadModule bw_module "mydisc/wamp/bin/apache/Apache2.2.14/modules/mod_bw.dll"


but no result. This is the same error:

=============
Syntax error on line 129 of: mydisc/wamp/bin/apache/Apache2.2.14/conf/httpd.conf
Cannot load mydisc/wamp/bin/apache/Apache2.2.14/modules/mod_bw.dll into serwer
=============


So, what now?
It looks like mod_bw.dll does not match to the this version of Wamp.


And this is lot of versions from website I downloaded this module (link):

ivn.cl/category/apache/

Lech

And direct link of (ivn.cl/category/apache/):

[ivn.cl]
