What you will do

• You create a small iLab exercise, a so-called minilab.
• You get lots of guidance and will learn a lot on successfully

communicating technical content, giving constructive feedback, receiving feedback properly, reviewing material, …

Which Topics are suitable?

• Have to be related with computer networks and distributed systems
• Also fit to the focus topics of this semester
• They are interesting, concise, explorative, have a scientific

component, ...

• They are suitable for 1-3h lab time.
• They have learning goals.
• They are not a tutorial only…

How to find a topic?

http://thehackernews.com/2016/05/openssl-vulnerability.html?m=1

Example for lab learning goals

• People doing our exercise will learn…
• What is SSL/ TLS? (Handshake, keygeneration, Zero Knowledge Proofs,

…)

• How to set up a webserver (e.g. Apache) with SSL r

i g h t .

• How to debug an SSL connection?
• How to attack an SSL connection (man-in-the-middle MITM,

Route redirects, …)

• How to detect that your connection is attacked?

http://thehackernews.com/2016/05/openssl-vulnerability.html?m=1

Example workflow for a lab preparation

• Research background on the attack.
• Rebuild the attack.
• Identify relevant learning outcome!

(VERY important: what shall the take home be?)

• Design an exercise around this outcome, e.g.
• Set a suitable topology up.
• Ask for interesting steps.
• Do some measurements. Interpret the results!

What do we expect next from you?

• What is your topic’s catchy title?
• Why did you choose this topic?
• What cool stuff do you want to communicate to those doing your

planned lab?

• What concrete theoretical background will one get?
• What could you imagine as interesting work done during the

hands-on?

vLab/CORE capabilities

• Can:
• Hosts:
• Emulate multiple (1-20+) Linux hosts
• Interact with them over the terminal
• Run (network) services (DHCP, DNS,…)
• Initially shared filesystem with vLab, after starting changes to

each host are limited to that host (Change only we did to CORE)

• Network
• Connect them arbitrary over network (IPv4/IPv6)
• Open Wireshark on any emulated Interface
• Manipulate network properties (bandwidth, loss,…)

vLab capabilities

• Depends:
• Internet Access (Possible, but not as easy as the other things)
• Use Software with GUI:
• Corefox -> Alias for Core to run firefox on a host
• CorePad -> Alias for Core to run a graphical Text editor on a host
• Not extensively tested with all kinds of software
• E.g. container based things might have issues
• -> Need to test that!

vLab capabilities

• Can’t:
• Add cabling while a setup is running (restart resets all changes)
• Emulate Cisco routers
• …? TBD
• -> This run is an experiment, CORE is very capable, but you

might run into issues!

• Talk to us, talk to your fellow students and we try to overcome

those.

Resources

• vLab Resources:
• https://ilabxp.com/vlab-the-virtual-internet-laboratory
• See Drop down of the vLab menu: Download, Install, CORE usage
• Soon: How to create your own setups
• General CORE Documentation: http://coreemu.github.io/core/
• Especially: Architecture, GUI, Node-Types, …
• Keep in mind:
• We modified it so that the hosts don’t share the filesystem after

starting a setup!
