Kali Linux Essentials Training

Download, unzip, and import the Kali Linux 2024.1 pre-built VM for VMware workstation, then configure memory, network, and login to access a ready-made Kali lab.

Navigate a first-time Kali Linux login, explore the desktop, icons, and panels, open Firefox and terminal, manage workspaces, and configure network, notifications, and power settings.

Explore the Linux file system structure, where everything is a file under the root directory /, organized as an inverted tree of directories like bin, sbin, dev, lib, and var.

Enable root login on Kali Linux by installing the kali root login package and setting a new root password, enabling graphical login as root.

Explore how the Linux kernel acts as the brain of the operating system, mediating between hardware and software, managing resources, memory, processes, file systems, and device drivers.

Update and upgrade Kali Linux with apt, maintain the correct repositories for a rolling release, and learn upgrade, full-upgrade, and dist-upgrade to improve security and performance.

Explore dpkg, a low level Debian package manager used in Kali Linux to install, remove, and manage packages, and compare it with apt's automatic dependency handling.

Master Kali Linux user and group management: add or delete users, set passwords, modify accounts with user mode, and manage groups and membership with group del and group mode.

Master input output redirection in Linux by redirecting input from files, directing stdout and stderr to files, appending or overwriting, piping, and using dev null to discard output.

Explore configuring Kali Linux network interfaces using multiple methods: network manager (GUI or NM cli), the network configuration file, ifconfig replaced by ip, f config, and systemd-networkd.

Configure interfaces with ip command replaces ifconfig and route; manage ip addresses, routes, mac addresses, and neighbors with ip link, ip address, ip route, and ip neighbor show.

Configure Kali Linux network interfaces using the graphical network manager and nmcli. Create, edit, and manage wired and wireless connections, and set IPv4 addresses, gateway, and DNS.

Learn to verify and troubleshoot Kali Linux network configuration with commands like IP address, IP route, ping, traceroute, tcpdump, dig, nslookup, and nmcli, plus dhclient, host, and arp.

Learn how to use ss to inspect socket statistics, including tcp/udp sockets, ipv4/ipv6, listening and established states, with filtering by destination ip, source ip, port, and state.

Explains u-mask as the default permission for new files and folders, with normal users 002 and root 022, generating 644 files and 755 directories, and how to adjust it.
