Explore RAID levels 0, 1, 5, 6, and 10, including striping, mirroring, and parity, to boost performance and fault tolerance. Learn each level's advantages, disadvantages, ideal uses, and rebuild considerations.

Learn how to practically implement raid 10 on ubuntu by creating an md array from four drives, monitoring rebuild progress, and preparing for drive replacement.

Learn to configure linux network interfaces, including ipv4 address classes, private vs public addresses, subnet masks, and mtu, using ifconfig to set ip, netmask, and broadcast.

Set up a static IP address on Ubuntu by manually configuring IP, network address, gateway, and DNS in the config file, restart, and verify with ping.

Configure a static IP on the 2023 Ubuntu server by locating the default gateway, editing netplan YAML to disable DHCP, set IP, name servers, routes, and applying netplan.

Monitor linux network services using commands to view connections, listening ports, and tcp/udp protocols. Capture packets with tcpdump, inspect routing and interfaces, and block hosts or networks as needed.

Learn to administer an Ubuntu Linux server remotely from Windows using OpenSSH server and PuTTY. Install the server and client, configure IPs, and securely transfer files and run commands.

Install and configure the Apache web server on Linux, explore main configuration files and sites-available and sites-enabled, and review access and error logs for basic site management.

Secure an apache web server against hacker attacks by hiding server name and version, toggling signature visibility, disabling directory browsing with -Indexes, and limiting requests to mitigate DDoS attacks.

Restrict access to specific directories by adding configuration lines, set options none and deny from all, and disable following symbolic links to defend the web server against hacker attacks.

Learn how to install and configure your own e-mail server, and explore how email flows between user agents, mail transfer agents, local domains, and DNS to deliver messages.

Learn how dns servers resolve a domain to an ip address, from local dns to root and tld, and how records like a, aaaa, mx, ns, and soa organize zones.
