Our Linux Networking course explores core concepts including TCP/IP, IPv4/IPv6, subnetting, and network troubleshooting. Ideal for IT professionals, it combines live instruction with hands-on labs using tools including Tcpdump and Wireshark to build practical, job-ready networking skills in Linux environments.
Linux Networking
Gain practical Linux network administration skills
Build essential Linux networking skills through hands-on practice with real-world configurations. You’ll focus on network design, interface setup, and protocol use, giving you the skills needed to manage real systems and preparing you for progression into advanced infrastructure, system administration or cyber security roles.
Learning objectives
- Understand Linux networking fundamentals
- Configure IPv4 and IPv6 settings
- Subnet IP ranges and manage routing
- Use Tcpdump and Wireshark for packet analysis
- Scan networks, ports and hosts
- Apply key protocols (SSH, DNS, DHCP, etc.)
- Customise and test Linux network interfaces
- Troubleshoot and monitor network performance
What you’ll learn
Gain a comprehensive understanding of Linux networking principles, tools and commands used in real-world environments. This two-day course builds your skills through hands-on tasks that simulate real network configurations, packet captures, and analysis. You’ll develop the confidence to troubleshoot, optimise and maintain Linux-based networks with clarity and precision.
Linux Network Architecture
Explore how Linux interacts with network hardware to support stable, high-performance connectivity. Learn about MAC addresses, switching, port behaviour and topologies including star and mesh. Practical labs reveal how latency, jitter and throughput affect performance, which is essential insight if you're responsible for maintaining, upgrading or designing resilient, efficient network infrastructure in Linux environments.
Dynamic Addressing and Subnet Planning
Master IP address allocation through static and dynamic methods, including CIDR-based subnetting and DHCP configuration in Linux. You’ll design and test subnet plans, configure interfaces and troubleshoot routing. These skills are vital for managing scalable, secure networks and ensuring efficient communication across expanding systems and infrastructure.
Traffic Capture and Analysis Techniques
Learn to analyse network traffic using Tcpdump and Wireshark. Capture packets, filter data and examine protocol headers to diagnose performance issues. Identify TCP, UDP, ICMP and ARP behaviours through real-world simulations, teaching you essential diagnostic skills for troubleshooting delays, detecting failures and maintaining high-performing, reliable Linux network environments.
Protocol Operation and System Services
Understand how core protocols such as DNS, DHCP, HTTP, FTP, SSH and NTP function in Linux environments. Explore client-server communication, service dependencies and diagnostic tools including systemd sockets and RPC. You'll also troubleshoot common issues like handshake failures and port conflicts, which is essential for maintaining stable, high-availability Linux network services.

FAQs
This course provides a focused overview of Linux networking essentials. You’ll explore physical and logical aspects of networks, including IP addressing, routing, and system configuration. Practical labs ensure you can apply tools and techniques confidently in real-world technical environments.
What’s the difference between Tcpdump and Wireshark, and when would I use each?
Tcpdump is ideal for quick packet captures on remote systems or minimal environments, while Wireshark provides advanced filtering and graphical decoding. You’ll use both in this course to compare outputs and select the best tool based on the scenario, giving you versatility across enterprise or constrained environments.
Will I learn to diagnose real-world issues, not just theory?
Yes. Each module includes lab-based exercises where you solve practical network problems such as unreachable hosts, incorrect IP setups, or misfiring services. These scenarios mirror challenges in operational IT environments, building your troubleshooting confidence.
How does this course support IPv6 network migration?
You’ll learn how to configure, test, and troubleshoot IPv6 networks from scratch. Topics include address allocation, auto-configuration, dual-stack support, and use of diagnostic commands. The labs ensure that you gain experience relevant to businesses modernising their network infrastructures.
Can I apply these skills to cloud-based Linux systems?
Definitely. While the course focuses on general Linux environments, the networking concepts, tools and troubleshooting methods are directly applicable to cloud platforms. You'll understand how to work with virtual interfaces, subnets, and diagnostics that are essential for supporting hybrid and cloud-native systems.
Does the course cover securing a Linux network?
Security is embedded across the course, particularly in areas like scanning, packet analysis, and service configuration. You'll learn how to identify suspicious traffic, limit open ports, and configure core services to reduce exposure. These practices form part of a wider network defence strategy.
