It queries sbl-xbl.spamhaus.org, taking advantage of the Spamhaus Block List (SBL) and the Exploits Block List (XBL).

1. Install the package

apt-get install libapache2-mod-spamhaus


Apache is automatically restarted and the module is enabled. If you would like to test the module you can add a line to your hosts file to make it think that your IP address is blocked (pico /etc/hosts)

127.0.0.4 1.0.168.192.sbl-xbl.spamhaus.org


Replace 1.0.168.192 with your IP address and reverse it. The IP address 192.168.0.1 should read 1.0.168.192.

By default, only POST, PUT, OPTIONS, CONNECT methods are blocked. You can add GET to the list of methods blocked in /etc/apache2/mods-enabled/mod-spamhaus.conf to block the spammers from seeing your website.

1. Download ionCube loaders

sudo wget http://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86.tar.gz


2. Extract

sudo tar zxvf ioncube_loaders_lin_x86.tar.gz


3. Move to a permanent location

sudo mv ioncube /usr/local/


4. Add reference to your php.ini file (sudo pico /etc/php5/apache2/php.ini)

zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.2.so


There are a few versions of the loader in the tar archive. Use the one that matches your PHP version.

5. Restart apache

sudo /etc/init.d/apache2 restart


1. Download a copy of Zend Optimizer / Guard from the location below and put it into /tmp

http://www.zend.com/en/products/guard/downloads


2. Extract

cd /tmp
sudo tar zxvf ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz


Replace with your actual filename

3. Create a directory to contain Zend optimizer

sudo mkdir /usr/local/lib/Zend


3. Move the Zend optimizer lib to a permanent location

sudo mv ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp/ZendOptimizer.so /usr/local/lib/Zend/


Your ZendOptimizer directory name may be different since it includes version numbers and platform. I'm using the 5_2_x_comp directory because I have PHP 5.2 installed.

4. Add reference to your php.ini file (sudo pico /etc/php5/apache2/php.ini)

zend_extension = /usr/local/lib/Zend/ZendOptimizer.so
zend_optimizer.optimization_level = 15


5. Restart apache

sudo /etc/init.d/apache2 restart


1. Install all required packages

sudo apt-get install tomcat6 tomcat6-admin tomcat6-examples


Tomcat depends on a lot of other packages and the package manager will take care of that

2. Make sure the service is responding by entering url similar to this one in a browser:

http://{ipaddress}:8080/


Replace {ipaddress} with the ip address of your server

3. Create user and roles for the manager app. Replace the contents of your current file with something like this: (sudo pico /etc/tomcat6/tomcat-users.xml)

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="manager" />
<role rolename="tomcat"/>
<user username="{username}" password="{password}" roles="tomcat,manager"/>
</tomcat-users>


Replace {username} and {password} with credentials of your choice.

4. Restart Tomcat

sudo /etc/init.d/tomcat6 restart


5. Enter the manager app with a browser

http://{ipaddress}:8080/manager/html
