Changing the Webmin Port from the Command Line
Changing the port on which Webmin runs after installation is also a pretty simple process. Simply edit the file miniserv.conf in the /etc directory where your Webmin configuration files were installed (this is likely one of the following: /etc/webmin, /usr/local/webmin/etc, or /opt/webmin/etc). You’ll find a port directive. Change this to whatever port you need Webmin to listen on, and then restart the Webmin web server.
Restarting the Webmin server can be accomplished in a few different ways depending on the OS and version. Under Red Hat Linux and its derivatives, for example, you would use the standard service command:
#/sbin/service webmin stop
#/sbin/service webmin start
If your OS does not have a standardized service control tool like service, you may use the standard Webmin stop and start scripts located in the Webmin etc directory:
# /etc/webmin/stop; /etc/webmin/start
The miniserv.conf file contains many other options, but you will only need to edit a few manually. Other common problems that users run into include restricting their access by IP. This can cause them a problem if their service provider changes the IP. Simply mistyping an IP can also lead to the same trouble. The remedy for this problem is to add the correct IP to the allow= directive and then restart the Webmin server.

Installing Perl Modules.
Perl Modules can be obtained from the CPAN (Comprehensive Perl Archive Network) at http://search.cpan.org.
The easiest way to install Perl modules on Unix is to use the CPAN module. For example:
shell> perl -MCPAN -e shell
cpan> install DBI
cpan> install DBD::mysql
DBD::mysql is the Perl5 Database Interface driver for the MySQL database.
To find a particular module, use the i command, followed by an expression that you want to search for:
CPAN.pm will go out to the CPAN mirrror that you selected, download the list of modules, and tell you which ones match the search word.
To install a module, just type:
cpan> install Time::CTime
CPAN.pm takes care of the whole process. It downloads the compressed file, unpacks it, builds it, and installs it all for you, unless there is a problem with the installation process. If there are other modules on which this module relies, it will also download and install those.

The simplest way to open up port 10000 is to use one of the Webmin firewall management modules, such as Linux Firewall, BSD Firewall or IPFilter Firewall. However, to access this you’ll need to run a brower on the same system as Webmin, and access it via the URL http://localhost:10000/.
The alternative is to login as root via SSH, and manually edit the firewall configuration file. On Redhat and derived systems, this is /etc/sysconfig/iptables, while on Debian it is /var/lib/iptables. The line you need to add is :
-A INPUT -p tcp -m tcp –dport 10000 -j ACCEPT
Once this line has been added, you will need to apply the firewall configuration. This is typically done with the command
/etc/init.d/iptables restart

Rootcheck is an open source rootkit detection and system auditing software.
How to use it
Download from :
http://www.ossec.net/rootcheck/files/rootcheck-2.0.tar.gz
* rootcheck requires the Perl Modules IO::Interface.
Rootcheck is a very simple software. Just unpack, compile and execute it. It will scan the system and print if it found or not anything.
-
wget http://www.ossec.net/rootcheck/files/rootcheck-2.0.tar.gz
-
tar -zxvf rootcheck-2.0.tar.gz
-
cd rootcheck-2.0
-
make all
-
./ossec-rootcheck
Rootkit detection
Criminals (also known as hackers) want to hide their actions, but using rootkit detection you can be notified when they (or trojans, viruses, etc) change your system in this way.
Active response
Take immediate and automatic responses when something happens. Why wait for hours when you can alert your admin and block an attack right way?
How To Scan the System
RootCheck. is an extremely useful open source software for servers since it scans the server and finds any problems on it.

Installing and Configuring CSF Firewall
ConfigServer Firewall & Security. A Stateful Packet Inspection (SPI) firewall, Login/Intrusion Detection.
This article demonstrates how to install and configure the CSF (configserver) firewall. CSF can be used on a wide range of Linux systems, including those running cPanel.
cd /tmp
wget http://www.configserver.com/free/csf.tgz
tar zxf csf.tgz
cd csf
sh install.sh
To configure CSF modify the config files in /etc/csf/ - or if you are running WHM you can modify the CSF settings in there. By default CSF opens the standard cPanel ports.
If you have APF + BFD you will need to disable it, you can use the following to do so:
