How to Limit Connections per IP using mod_limitipconn on cPanel

How to limit connections per IP in a cPanel hosting server :
there is an Apache module named mod_limitipconn which will take care of it for us.
first download the latest version of mod_limitipconn from this site : http://dominia.org/djao/limitipconn2.html
decompress and install it.
at current time the latest version is 0.23.

1.wget http://dominia.org/djao/limit/mod_limitipconn-0.23.tar.bz2
2.tar jxvf mod_limitipconn-0.23.tar.bz2
3.cd mod_limitipconn-0.23
4.usr/local/apache/bin/apxs -cia mod_limitipconn.c

next step is to add the required configuration to the Apache config file , we can add this directly to the end of httpd.conf file but the problem is that if we do this , the httpd.conf will be overwritten by easyapache so we will use include files to add our config.
login into your WHM panel , and follow the following menu items :
Main >> Service Configuration >> Apache Configuration >> Include Editor
on the Post VirtualHost Include section , choose All Versions from drop down menu and add the following config into it :

1.
2.
3.MaxConnPerIP 10
4.NoIPLimit images/*
5.
6.

then click on update and restart Apache server.
