HOWTO : Mod_Bandwidth for DA

[jeffery]

************************************
Mini-Howto on installing Mod_BandWidth
Version 2.0.5
Date : 23 July 2004

Tested on Redhat 9
************************************

Step 1 - Download mod_bandwidth

#cd /usr/local/directadmin/customapache (You may change this)
#wget ftp://ftp.cohprog.com/pub/apache/module/1.3.0/mod_bandwidth.c

Step 2 - APXS Compilation
#/usr/sbin/apxs -c ./mod_bandwidth.c -o /etc/httpd/modules/mod_bandwidth.so

Step 3 - Link Directory
#mkdir /tmp/apachebw
#mkdir /tmp/apachebw/link
#mkdir /tmp/apachebw/master
#chown -R apache:apache /tmp/apachebw

Step 4 - Modify Apache Conf
#vi /etc/httpd/conf/httpd.conf

Place those lines in whatever place you want:
<IfModule mod_bandwidth.c>
BandWidthDataDir /tmp/apachebw
BandWidthModule On
</IfModule>


Step 5 - Customize Virtual Host Limitation
You may now customize each virtual host's httpd.conf located in
/usr/local/directadmin/data/user/{username}/

by adding "BandWidthModule On" (without quotes) in each <VirtualHost>, and mod_bandwidth tag like "BandWidth" inside <Directory> tag.


Step 6 - Do a safe apache restart
#service httpd restart


OK! You may now upload a huge file (enough to test) to a dummy site that you limited to test.

:)

may i know what does mod_bandwidth do and what's it's advantage over default DA bandwidth function and mod_throttle?

thanks.

[jeffery]

mod_bandwidth can limit per user/per domain bandwidth, such as 100KB/s.

For more information, refer to their website:

http://www.cohprog.com/v3/bandwidth/intro-en.html

[sander815]

if i compile this, and don't add any user, does apache work as normal, withoutany limits?

[jeffery]

The module is set to be disabled unless you add

"BandWidthModule On"
:)

[sander815]

i don't get step 5:
Step 5 - Customize Virtual Host Limitation
You may now customize each virtual host's httpd.conf located in
/usr/local/directadmin/data/user/{username}/

by adding "BandWidthModule On" (without quotes) in each <VirtualHost>, and mod_bandwidth tag like "BandWidth" inside <Directory> tag.


you mean like this:
[code]<VirtualHost 81.23.xxxx:80>

BandWidthModule On
ServerName www.xxxx.nl
ServerAlias www.xxxl dtp.fxxe.nl
ServerAdmin webmaster@xxx
DocumentRoot /home/xxx/domains/xx/public_html/dtp
ScriptAlias /cgi-bin/ /home/xxx/domains/xxxnl/public_html/$

User xxx
Group xxx
CustomLog /var/log/httpd/domains/xxx.bytes bytes
CustomLog /var/log/httpd/domains/xxx.dtp.log combined
ErrorLog /var/log/httpd/domains/xxx.nl.dtp.error.log
<Directory /home/xxxx/domains/xxx.nl/public_html/dtp>
Options +Includes -Indexes
BandWidth
php_admin_flag engine ON
php_admin_flag safe_mode OFF
</Directory>



#php_admin_value open_basedir /home/xxx/:/tmp/:/var/www/:/usr/loc$

</VirtualHost>

and where do i set f.i. 300 kb/s?

[jeffery]

Yes.

You may set

BandWidth all 1024


where the unit of 1024 is "Bytes/s".

[sander815]

is this step from the docs for mod_bandwidth not neccessary?:

* Add the following lines to your httpd.conf file :
LoadModule bandwidth_module libexec/mod_bandwidth.so
AddModule mod_bandwidth.c

Those directives should be placed at the begining of the list so that
the module will be given the lowest priority and be executed after others modules.

[sander815]

so this should do it:
<VirtualHost 81.23.xxxx:80>

BandWidthModule On
ServerName www.xxxx.nl
ServerAlias www.xxxl dtp.fxxe.nl
ServerAdmin webmaster@xxx
DocumentRoot /home/xxx/domains/xx/public_html/dtp
ScriptAlias /cgi-bin/ /home/xxx/domains/xxxnl/public_html/$

User xxx
Group xxx
CustomLog /var/log/httpd/domains/xxx.bytes bytes
CustomLog /var/log/httpd/domains/xxx.dtp.log combined
ErrorLog /var/log/httpd/domains/xxx.nl.dtp.error.log
<Directory /home/xxxx/domains/xxx.nl/public_html/dtp>
Options +Includes -Indexes
BandWidth all 25600
php_admin_flag engine ON
php_admin_flag safe_mode OFF
</Directory>



#php_admin_value open_basedir /home/xxx/:/tmp/:/var/www/:/usr/loc$

</VirtualHost>

this sets the bandwidth cap to all directories under public_html? also subdomains?

Those lines are added by DA, but they are not loaded because mod_bandwidth is not loaded.




so this should do it:

ErrorLog /var/log/httpd/domains/xxx.nl.dtp.error.log
<Directory /home/xxxx/domains/xxx.nl/public_html/dtp>
Options +Includes -Indexes
BandWidth all 25600
php_admin_flag engine ON
php_admin_flag safe_mode OFF
</Directory>



#php_admin_value open_basedir /home/xxx/:/tmp/:/var/www/:/usr/loc$

</VirtualHost>


When you put "bandwidth" in <directory>, that means this directory and its sub-directories are limited.

its limiting indeed, on my testdomain, but it seems like i can't get more then 100 kb/s dlspeed, i am at BandWidth all 1024000, but still, 100 kb/s is max dl speed. I would like to limit at around 300 kb/s, 100 is a bit too low

[jlasman]

What bandwidth to you seem to get for your test site when you turn limiting off?

Jeff

[sander815]

when i put ''bandwith all 0'' i get full speed, 100%[====================================>] 29,902,848 7.70M/s ETA 00:00


when i put ''bandwith all 262144'' i get 12% [===> ] 3,660,624 88.96K/s ETA 04:48, that should be around 256 kb/s, if i calculate right. Higher numbers produce same speed of around 90 kb/s

[jlasman]

Well, then forget my idea... it's been disproved.

Don't know.

:(

Jeff

[jeffery]

You have to use

"BandWidthPulse"

according to the author.

But I haven't test it yet! :)

[sander815]

any1 solved this problem?

when do you have time to test this?

[sander815]

finally found a working soplution:
add into the global httpd.conf:
BandWidthPulse 500000

so, like this:
<IfModule mod_bandwidth.c>
BandWidthDataDir /tmp/apachebw
BandWidthModule On
BandWidthPulse 500000
</IfModule>

that worked for me

[BadSpeed]

I'm using this mod.
And everytime there is an update of DA, the directory in /tmp/apachebw gets deleted and I have to recreate before rerunning httpd.
Is there a way to recreate those directories after an update to avoid down time :s

[TMC]

Hi, please could someone update this thread, especially the following question?Originally posted by BadSpeed
everytime there is an update of DA, the directory in /tmp/apachebw gets deletedAlso, what is the meaning of "BandWidthPulse", what does its value represent, and how does the value of "BandWidthPulse" relate to the value of "BandWidth"?

TIA!

[BadSpeed]

The pulse is the latence that use the module in order to limit the bandwidth ... from what I understand :P

For my problem I have found a way that prevent this error. Simply move those directory to a new spot ... like /apachebw
Just make sure to make the changes in your httpd.conf :P

[redeye]

I have:

httpd.conf:

<IfDefine HAVE_BANDWIDTH>
LoadModule bandwidth_module modules/mod_bandwidth.so
</IfDefine>

<IfDefine HAVE_BANDWIDTH>
AddModule mod_bandwidth.c
</IfDefine>

<IfModule mod_bandwidth.c>
BandWidthDataDir /tmp/apachebw
BandWidthModule On
BandWidthPulse 500000
</IfModule>


/usr/local/directadmin/data/user/{username}/httpd.conf

#php_admin_value open_basedir /home/xyz/:/tmp/:/var/www/:/usr/local/lib/php/:/etc/virtual/

</VirtualHost>

after service httpd restart i get:
Syntax error on line 13 of /usr/local/directadmin/data/users/xyz/httpd.conf:
Invalid command 'BandWidthModule', perhaps mis-spelled or defined by a module not included in the server configuration
[FAILED]

I've checked the directory:
ll /etc/httpd/modules/mod_bandwidth.so
ls: /etc/httpd/modules/mod_bandwidth.so: No such file or directory

So is it not default installed??? If so, how do I get it installed?

[BadSpeed]

read the first port of this topic :p

[redeye]

done that allready, and it's working. I got confused by the remarks that DA included this mod by default. :D

Thx anyhow

[nbhosting]

Seting a value with "BandWidthPulse", will change the algorithm so that the server will always wait the same amount of time between sending packets but the size of the packets will change. The value is in microseconds. For example, if you set "BandWidthPulse 1000000" (1 sec) and the bandwidth available is of 512B, the sever will transmit 512B, wait 1 second, transmit 512B and so on.

[@how@]

thanks, work fine :D

[duock]

hi guy

i got a question is

is BandWidth all 25600 mean one ip bandwidth or the whole ip bandwidth?

[milan]

no bandwidth per user

[Aspegic]

I wish someone would write a DA plugin for mod_bandwidth, with options for:

1. install mod_bandwidth
2. uninstall mod_bandwidth
3. modify bandwidth settings for all users
4. modify bandwidth settings per user
5. list all users with their bandwidth settings

In case you're reading this jon, maybe an idea for jtbox? ;)

[Alliance1911]

is it possible with this to have it work with a certain process? such as shoutcast, so lets say i have a shoutcast plan set got 64kbps and want to have it at that speed but also maintaining 100mbps on web browsing on the site for 1 certain account??

[rusel]

Hi, I`ve got everything on place, mod_bandwidth.so is in modules etc, and it is loaded, but I`m getting this
Syntax error on line 12 of /usr/local/directadmin/data/users/download/httpd.conf:
Invalid command 'BandWidthModule', perhaps mis-spelled or defined by a module not included in the server configuration
master:/etc/httpd# mcedit /usr/local/directadmin/data/users/download/httpd.conf

when I add after
<VirtualHost 80.86.84.29:80>
BandWidthModule On

.... everything is set ok... I have to add <ifmodule mod_bandwidth.c> to havent errors, but then bandwidth does not work :/ have u got any ideas? apache 1.3.

[works]

I have followed all the instructions on first post and if I place the code below in httpd.conf any where as mentioned by the author of this thread I was not able to get mod_bandwidth to work.

I have got it working on when I placed the code as below above <IfModule mod_userdir.c>

<IfModule mod_bandwidth.c>
BandWidthDataDir /tmp/apachebw
BandWidthModule On
BandWidth all 25600
</IfModule>

<IfModule mod_userdir.c>
#UserDir public_html
UserDir disabled
</IfModule>

I am not sure why, may be some conflict in order or something when placed anywhere. But placing the mod_bandwidth code as shown above worked for me.
