v56 v57 29 29 30 30 === Client-to-Server Traffic through a Proxy === 31 Now we'll use a proxy to make this traffic a bit more anonymous. A proxy will mask the source and destination of the traffic from both the client and the server by working as a go between for the two nodes. Repeat the tcpdumpcommand `sudo tcpdump -i eth0 -s 0 -x -w /tmp/throughproxy.pcap` from the server node. However, now the user connected to Alice should enter the command `env http_proxy=http://proxy:8888 wget http://server/cgi-bin/ip.cgi` This command changes an environmental setting and sends the `wget` command through the proxy on port 8888. Thanks to the `tcpdump` command, we have a copy of this traffic as well.31 Now we'll use a proxy to make this traffic a bit more anonymous.

As the name suggests onion routing alters the data flow through a minimum of 3 relays, each adding another layer of anonymity, because the packets of data only know the address of the next relay and the previous relay. Repeat the `tcpdump` command `sudo tcpdump -i eth0 -s 0 -x -w /tmp/throughtor.pcap` from the server node. Now, the user on Alice should use the command `torify wget http://server/cgi-bin/ip.cgi` 36 37 37 38 38 == Step 3 Analyzing the Traffic Data ==
