Study Notes

Debian Overview

  • Debian is a prominent Linux distribution renowned for stability, security, and adherence to free software principles.
  • Developed since 1993, it forms the basis for many other distributions.
  • Utilized in various computing environments (desktops, servers).

Installation and Setup Guide

  • Download the Debian ISO from the official website.
  • Create a bootable USB drive (using tools like Rufus or Etcher).
  • Boot the computer from the USB drive (access boot menu via specific key like F2, F10, F12).
  • Choose language, location, keyboard layout, hostname, domain name, root password, and user details.
  • Guided partitioning is recommended for novice users.
  • Configure network settings, package surveys, and install GRUB bootloader.

Package Management

  • Core tools are dpkg (low-level, individual .deb package management) and APT (higher-level, dependency resolution, package retrieval).
  • APT handles dependencies and simplifies command syntax.
  • Maintains system stability and security by ensuring consistent package versions and dependencies.

System Requirements

  • Minimum requirements: 256 MB RAM, 2 GB disk space (basic, non-graphical install).
  • Recommended requirements: More RAM and disk space for smooth graphical desktop environments (e.g., GNOME, KDE).
  • Compatible with diverse systems (embedded devices to supercomputers).

Desktop Environments

  • GNOME: Default, modern, minimalist.
  • KDE Plasma: Customizable, feature-rich, traditional.
  • MATE: Traditional, based on GNOME 2.
  • Cinnamon: Modern take on traditional desktop.
  • Choose during installation or install later.

Debian in Server and Desktop Environments

  • IRC Channels: #debian (main), #debian-devel (development).
  • Forums: forums.debian.net
  • Documentation: on the official Debian website and wiki.

Customization and Optimization

  • Lightweight desktop environments (Xfce, LXDE) for older hardware.
  • Adjusting swappiness in /etc/sysctl.conf to improve memory management.
  • Disabling unnecessary services, regular updates, and firewall configuration for security.

Security Policies and Practices

  • Active vulnerability monitoring and security advisories via debian-security-announce.
  • Following best practices and staying updated on security updates enhances system security.

Release Branches

  • Stable: Officially released version, recommended for production, security updates only.
  • Testing: Packages for the next stable release (frequent updates, possible bugs).
  • Unstable (Sid): Active development branch (latest software, most volatile).

Advanced Networking

  • UFW (Uncomplicated Firewall) for simplifying iptables configurations (install with apt).
  • Custom port rules and IP-based restrictions for tailored security.
  • Monitoring and testing configurations are crucial.

Software Development

  • Debian provides a rich ecosystem, including essential development tools (GCC, G++, Make), and support for various languages.
  • Installation and updating of required tools is simplified via the package management system.
  • Developers can utilize backports for bleeding-edge versions or utilize containerization (Docker, Podman).

Debian Derivatives

  • Debian is the base for Ubuntu and its derivatives like Linux Mint.
  • Debian's pack format and APT are inherited but Ubuntu focuses on user-friendliness and frequent updates.
  • Linux Mint builds on Ubuntu, adding proprietary drivers and codecs.

Troubleshooting

  • Check system logs, update the system, review recent configuration changes, and verify hardware compatibility.
  • Utilize container technologies (Docker, LXC) to isolate applications.
  • Leverage the Debian community for assistance.

Upcoming Features and Roadmap

  • Debian 13 ("Trixie") is anticipated in 2025, continuing with stability, adopting Linux kernel 6.12, expanding architecture support (RISC-V).
  • Security enhancements, better support for secure boot, and advanced encryption methods are part of the roadmap.

DebianEdu

  • DebianEdu (Skolelinux): Distribution tailored for educational institutions, pre-loaded with educational software (astronomy, chemistry, programming, mathematics) and centralized terminal server management.

Cloud Platforms

  • Debian images are available on AWS (Amazon Machine Images - AMI) and Azure (cloud-init enabled images).

Minimal Installations

  • Debian Netinstall image (250 MB) for a minimal installation.
  • Allows for selection of only essential packages.
  • Consider using minimal window managers like i3 or openbox.

Multimedia and Gaming

  • Provides tools like VLC media player, GIMP, Audacity for multimedia.
  • Gaming compatibility has improved with Steam and Proton.
