Free Protocol Inspector
Objective:
You will find here instructions on how and where to download a free protocol inspector.
It’s not real pretty but it works…and it’s free. I use it through out this book.
Step-By-Step Instructions:
1. Go to www.ethereal.com (note: only one “r” the site—figure 1-- with two “rr’s” is a
magazine…you will know you are at the wrong page if you see something in
French—figure 2).
Figure 1—The “right” site.
Figure 2—The “wrong site.”
2. On the left-hand side of the “Information” window click on “Download.”
3. Scroll down until you find the link for the windows operating system (see figure 3).
4. Click on the link for “local archive” (see figure 3).
Figure 3—Click on “local archive.”
Figure 4—Click on Winpcap.
5. You need a driver library to make this work. Click on the Winpcap packet driver
library link (see figure 4).
6. Click on “downloads” on the left side tool bar (see figure 5).
