How to install Chkrootkit 12 on Debian

Chkrootkit is a powerful Unix utility designed to help system administrators protect their systems from rootkits. Rootkits are a type of malware known for gaining unauthorized access to computer systems and pose a serious threat to the security of Debian Linux.

Installing Chkrootkit 12 Bookworm on Debian

Ensuring that systems are kept up to date is a fundamental best practice in system administration. Before installing new software, run the following command to update your Debian system:

sudo apt update
sudo apt upgrade

This command will update the package list for upgrades and new package installations.

Step 2. Install Chkrootkit 12.

• Method 1: Install via APT

After updating your system, you can now install Chkrootkit. Since Chkrootkit is available in Debian repositories, the installation process is very simple. Execute the following command to install Chkrootkit:

sudo apt install chkrootkit

This command will get the Chkrootkit package from the Debian repository and install it on your system.

After the installation is complete, it is a good idea to verify it. You can do this by checking the Chkrootkit version. Run the following command:

sudo chkrootkit -V

The first step is to download the Chkrootkit source code from its official FTP site. You can download files from the command line using the wget command:

wget ftp://ftp.chkrootkit.org/pub/seg/pac/chkrootkit.tar.gz

Before compiling Chkrootkit from source code, you need to install some necessary development tools. The following command will install the GCC compiler, the "make" utility, and a set of libraries and utilities called "build-essential" that are required to create executables from source code:

sudo apt install gcc make build-essential

After installing the necessary development tools, you can extract the Chkrootkit source code and compile it. Navigate to the directory where you downloaded the source code and run the following command:

tar -xzf chkrootkit.tar.gz
cd chkrootkit-*
make sense

As with the APT method, you can verify the installation by checking the Chkrootkit version:

./chkrootkit -V

After installing Chkrootkit, you can now scan your system for potential rootkits. To do this, run Chkrootkit using the following command:

sudo chkrootkit
