How do I learn using both the TUI and the Web GUI?

Clone https://github.com/1nc0gn30/30-days-of-Linux-Fundamentals and run ./control-panel for the native C terminal TUI (with built-in Markdown reader, Flashcard Arena, and /tmp sandbox shells), or use the Astro Web GUI for browser command drills, XP tracking, and visual chmod/FHS calculators.

Is 30 Days of Linux Fundamentals completely free?

Yes, 100% of the 30 days, 90 study guides, C TUI drills, and web tools are open-source and unlocked by default with zero paywalls.

Overview

In this session, we'll dive into Networking Basics. We'll explore essential networking commands and concepts.

Lessons

Viewing Network Configuration (`ifconfig`)

The ifconfig command displays or configures network interfaces.

Examples:

ifconfig : Display all active interfaces

ifconfig eth0 : Show configuration of 'eth0' interface

ifconfig eth0 up : Activate the 'eth0' interface

ifconfig eth0 down : Deactivate the 'eth0' interface

Pinging a Host (`ping`)

The ping command sends ICMP ECHO_REQUEST packets to network hosts.

Examples:

ping google.com : Ping Google to check connectivity

ping -c 4 google.com : Send 4 ping requests to Google

ping -i 0.5 google.com : Set interval to 0.5 seconds between requests

Traceroute to a Host (`traceroute`)

The traceroute command shows the path packets take to reach a network host.

Examples:

traceroute google.com : Trace route to Google

traceroute -n google.com : Trace route without resolving hostnames

Displaying Network Statistics (`netstat`)

The netstat command displays network connections, routing tables, and interface statistics.

Examples:

netstat : Show all active connections

netstat -r : Display routing table

netstat -i : Show network interfaces

Testing Port Connectivity (`nc` or `netcat`)

The nc command is a versatile networking tool for reading from and writing to network connections.

Examples:

nc -zv google.com 80 : Check if port 80 is open on Google

nc -l 1234 : Listen on port 1234 for incoming connections

nc google.com 80 : Connect to port 80 on Google

Quiz Questions

1. Question: What command would you use to view the configuration of all active network interfaces?
- Answer: ifconfig

2. Question: Which command would you use to send 4 ICMP ECHO_REQUEST packets to google.com?
- Answer: ping -c 4 google.com
