Assume the following:

include "range.h"

using namespace mepcotterell;

Then you can do cool stuff like this:

mepcotterell

*.class

Fun with tcpdump and hexdump

Here is some information that I've found/discovered from playing around with packets. The following is presented in an adhoc tutorial style. Hopepully you find it interesting.

Something that I found useful was the ability to actually capture the raw UDP packet using tcpdump utility. In the following example, we'll capture a DNS query packet and save it to a file.

Open up two terminal windows. In one window, type the following:

#!/usr/bin/env python3
