Rkhunter Installation

Download from

http://kent.dl.sourceforge.net/project/rkhunter/rkhunter/1.3.4/rkhunter-1.3.4.tar.gz

Rootkit Hunter (RKH) is an easy-to-use tool which checks computers running UNIX (clones) for the presence of rootkits and other unwanted tools.

What are rootkits? Most times they are self-hiding toolkits used by blackhats, crackers and scriptkiddies, to avoid the eye of the sysadmin.

Unpacking the tar file should produce a single directory called ‘rkhunter-’. Where ” is the version number of rkhunter being installed. For example, the rkhunter-1.3.0.tar.gz tar file will produce the ‘rkhunter-1.3.0′ directory when unpacked. Within this directory is the installation script called ‘installer.sh’.

To perform a default installation of RKH simply unpack the tarball and, as root, run the installation script:

RKH installation supports custom layouts. To show some examples run:

As an another example, to install all files beneath /opt, run:

The default installation process will install a configuration file, called ‘rkhunter.conf’, into the ‘/etc’ directory.

To run RKH, as root, simply enter the following command:

By default, the log file ‘/var/log/rkhunter.log’ will be created. It will contain the results of the checks made by RKH.

To see what other options can be used with rkhunter, enter:

DirectAdmin Installation

Control panel for web hosting companies running Red Hat 7.x, 8.x, 9.x, Red Hat Enterprise and FreeBSD.

Requirements

- Clean OS install
- At least one external IP address (NAT/LAN-based systems will NOT work)
- SSH installed, gcc and g++ installed
- Client account at https://www.directadmin.com/clients

Installation!

You *have* to add “AllowUsers username” to /etc/ssh/sshd_config before you log out from root or you’ll lose root on the server forever, and you’ll have to format.

Login as root and download the setup.sh file

Use “fetch” instead of “wget” on FreeBSD systems.

Change permissions on the setup.sh file

Run the setup script!

You will be prompted for a client ID number, license ID number, and hostname.

Important: The hostname should not be the same as the primary domain name. e.g. example.com is not a good hostname, where server.example.com is. Having the same host/main domain name will cause e-mail and FTP problems. Also, please make sure the hostname resolves once you setup DNS.
