About LimitIPConn
This is the distribution page for the Apache module mod_limitipconn.c, which allows web server administrators to limit the number of simultaneous downloads permitted from a single IP address

Official site: http://dominia.org/djao/limitipconn.html

well does this thing work with Cpanel ?
Answer :: Yes, it does.

Installing mod_limitipconn.c

Installing this was quick and easy. Login to your server through shell as the root user.

# wget http://dominia.org/djao/limit/mod_limitipconn-0.22.tar.gz
# tar -xzvf mod_limitipconn-0.22.tar.gz
# cd mod_limitipconn-0.22
# nano Makefile
Find
APXS = apxs
CHANGE TO:
APXS = /usr/local/apache/bin/apxs
Save

#make
#make install

This adds the module to httpd.conf and backs up the old configuration from httpd.conf.new

# vi /usr/local/apache/conf/httpd.conf
It should have added the following:

LoadModule limitipconn_module libexec/mod_limitipconn.so
and
AddModule mod_limitipconn.c

Now we need to setup the configuration for the site you want to add the limits to. Search the domain you want and go to the configuration for it in httpd.conf

You should be at the part like this:


ServerAlias www.domain.com domain.com

Add the following configuration that you want, this restricts 2 directories I have on my site to prevent users from downloading more than 1 video at a time, I have 2 separate rules.



MaxConnPerIP 1
# In this case, all MIME types other than audio/mpeg and video*
# are exempt from the limit check
OnlyIPLimit audio/mpeg video



MaxConnPerIP 1
# In this case, all MIME types other than audio/mpeg and video*
# are exempt from the limit check
OnlyIPLimit audio/mpeg video





So my whole entry for the domain looks like this:


ServerAlias www.domain.com domain.com
ServerAdmin webmaster@domain.com
DocumentRoot /home/domain/public_html
BytesLog domlogs/domain.com-bytes_log
ServerName www.domain.com

php_admin_value open_basedir "/home/domain:/usr/lib/php:/usr/local/lib/php:/tmp"



MaxConnPerIP 1
# In this case, all MIME types other than audio/mpeg and video*
# are exempt from the limit check
OnlyIPLimit audio/mpeg video



MaxConnPerIP 1
# In this case, all MIME types other than audio/mpeg and video*
# are exempt from the limit check
OnlyIPLimit audio/mpeg video



User domain
Group domain
CustomLog domlogs/domain.com combined
ScriptAlias /cgi-bin/ /home/domain/public_html/cgi-bin/



Save httpd.conf


Test Apache Configuration
# apachectl configtest start
Make sure it comes back ok without errors

# /scripts/restartsrv_httpd

Apache will restart. Try it out. Go to your limited directory and try to download 2 things (2 depends on your IP limit you set). You should get forwarded to a 503 Temporary Service page. We can customize that as well.

Any suggestions or questions are welcome.
