This document provides a comprehensive guide on setting up a Linux server without a graphical user interface (GUI) to run multiple services including DHCP, DNS, a web server with MariaDB for database management, and GLPI for internal resource management. It also covers the setup for remote server management via SSH and includes additional software installations.

• DHCP Server Configuration
• DNS Server Configuration
• Web Server and MariaDB Setup
• Remote Management via SSH
• Additional Software
• Weekly Backup Configuration
• Conclusion

For the project, we've set up two virtual machines (VMs) to create a controlled and isolated environment:

Client VM running Kali Linux: Chosen for its comprehensive suite of security and penetration testing tools, allowing us to assess and ensure the security of our server setup.

Server VM running Ubuntu: Hosts our core services including DHCP, DNS, Apache with MariaDB, and GLPI, providing a stable and widely-used platform for server-side configurations.

sudo apt-get update
sudo apt-get install isc-dhcp-server

• File Location: /etc/dhcp/dhcpd.conf
• Scope Definition: Define a subnet with a range of IP addresses to be dynamically allocated to clients.

subnet 192.168.64.0 netmask 255.255.255.0 {
  range 192.168.64.10 192.168.64.100;
  option domain-name-servers 192.168.64.5;
  option routers 192.168.64.1;
}

Service Management: Start and enable the DHCP service.

sudo systemctl start isc-dhcp-server
sudo systemctl enable isc-dhcp-server

sudo apt-get install bind9

• File Location: /etc/bind/named.conf
• Zone Files: Located in /etc/bind/zones/(if you organize your zones in a separate directory).
• Scope Definition: Define a subnet with a range of IP addresses to be dynamically allocated to clients.

Example zone definition :

zone "local.becode" IN {
    type master;
    file "/etc/bind/zones/db.local.becode";
};

sudo systemctl start bind9
sudo systemctl enable bind9

sudo apt-get install apache2

sudo apt-get install mariadb-server

• Download GLPI and extract it to the web server's root directory.
• Create a MariaDB database for GLPI.
• Access https://192.168.64.6/glpi to run the web installer.

• Ensure SSH is installed (openssh-server package).
• Edit /etc/ssh/sshd_config for any specific configurations.
• Restart SSH service to apply changes.

• LibreOffice: For office productivity tools.
• GIMP: For image editing.
• Mullvad VPN: For secure internet access. Note: Install the VPN client as per the official documentation.

Set up a cron job to back up configuration files weekly.

• Edit the crontab with sudo crontab -e.

• Add a line for the backup script, e.g., 0 3 * * 0 /path/to/backup_script.sh, to run it weekly.

sudo systemctl status isc-dhcp-server
sudo systemctl status bind9
sudo systemctl status apache2
sudo systemctl status httpd
sudo systemctl status mariadb
sudo systemctl status mysql
sudo systemctl status ssh

Conclusion This server setup provides a solid foundation for managing network services and hosting internal resources. Regular backups ensure configuration persistence and disaster recovery capability
