About You

• hello 👋

How the Workshops Work

• choose your level of interaction based on your energy - camera off / muted is totally OK
• if you are usually quiet in workshops, please feel free to take up space here
• if you are usually confident in workshops, please consider making space for others
• interactive “lectures” about a particular topic
• prepared lab tasks
  • build a network to a spec
  • troubleshoot a pre-built network
• learning networking isn’t linear - we will sometimes venture into uncharted territory, and then come back to talk about what we discovered.
• tech stack:
  • containerlab - orchestration tool
  • containerlab discord: https://discord.gg/fbcMCrQ4
  • hetzner - linux VMs
  • diagrams.net - diagrams

How Much the Workshops Cost

• if you have no income, please don’t pay anything
• if you have an income, please help me to cover costs
  • there is a donation link at the top of the workshops page that looks like this -> 💜 donate 🙏
• if your company will help cover your cost, I can send you a formal invoice (I am an Einzelunternehmer with a VAT ID)

Roadmap

• this roadmap is negotiable
• Season 1 was fast and wide, Season 2 will be slower and more “linux”-y
• it’s hard to learn networking in a linear fashion
• so we will jump around from topic to topic, getting deeper each time

Roadmap

• Layer 2 and Layer 3
  • tcpdump
  • MAC addresses and IP addresses (IPv4 and IPv6)
  • Packet formats, headers, shims
• TCP vs UDP
  • Connection-based vs Connectionless
  • the Three-Way Handshake
  • TCP windowing for flow control
• Firewalls and Access Control Lists (ACLs)
  • block ur friends
  • ufw vs iptables vs Appliances
  • faking your source IP
• Networking in Linux
  • the ip command
  • network namespaces
  • docker
• Network Programming
  • writing your own network utilities
• Encapsulation
  • VPNs and Tunneling
  • Onion Ring
  • GRE, IPSec, SSH tunnels

That’s it

Please enjoy :-)
