    1818Log onto the proxy node and use the command: `sudo /proj/DeterTest/runme.proxy` this will run a script which installs and sets up [https://banu.com/tinyproxy/ tinyproxy] on the node. The proxy is now set up!  We'll get to using it in a little while.

     20== Step 2 Generating and Listening to Network Traffic ==
    2121We are now ready to begin learning!  One person needs to connect to either Alice while another person logs into the server1 node (or server2 if you choose).   From the server node type the command `ifconfig` This will show the ethernet links that the node is using.

    2525Find the one that shows an inet address of 10.x.x.x In the example above it is eth0. Yours may be different, but that is still ok.
    26 Then type the command `sudo tcpdump -i eth0 -s 0 -x -w /tmp/tcpdump.pcap` This will begin listening to the traffic that comes through this node and that specific ethernet link, eth0 in the example, and write the data out to the file tcpdump.pcap in the tmp diretory.  At this time, the person connected to Alice will enter the command `wget http://server1/cgi-bin/ip.cgi`  This saves a local copy of the web page set up on the server, and by doing so generates HTTP traffic to examine.

We were able to listen in on this traffic thanks to the tcpdump command.
