An Exercise in Anonymity

Step 1 Setting Up the Network

Swap in the Experiment using this NS file​

Then log in to users.isi.deterlab.net through ​Putty. For help on logging onto Putty check out this tutorial.

Setting up apache

We need to generate traffic in our network and one of the easiest ways to do that is with HTTP traffic, so we need to set up a server and a web page. Connect to Server 1 and use the command: sudo /proj/DeterTest/runme.nodeA This will run a script with Apache 2 which sets up the server and web page and displays the users IP address on the Server 1 node. When prompted "Do you want to continue [Y/n]?" select Y Once the script is done running, the server is now set up and we can generate traffic! You can check this by typing w3m http://localhost/cgi-bin/ip.cgi which should display your IP address.

It should look like this. Repeat this process on Server 2

Deciding which node you will be using

  1. To begin one person always needs to connect to Server1
    1. In order to connect use the command ssh <node>.<experiment>.<group> for example ssh Server1.cadet-test2.DeterTest
    2. If this is your first time connecting to the node you will be asked to accept the fingerprint, just type yes and you will be connected
  2. If there are multiple users this is the order they should connect to:
    1. Proxy node
    2. Alice
    3. Server2
    4. Bob
    5. TorRelay1
    6. TorRelay2
    7. TorRelay3

Setting up the proxy node

  1. From Proxy use the command: sudo /proj/DeterTest/runme.proxy
  2. The proxy is now set up!! We'll get to using it in a little while.

Viewing Network Traffic ==

We are now ready to begin learning! One person SSH into either Alice or Bob while another person logs into the server node. From the server node type the command CHASE I DON'T KNOW THE TCPDUMP COMMAND this will begin listening to the traffic that comes through this node. From Alice type w3m http://server1/cgi-bin/ip.cgi This is how Alice is attempting to view the web page set up on the server, generating traffic we can see.
