Use Wireshark to inspect packets on your network. Scott Reeves illustrates how you can use Wireshark to inspect packets, looking specifically at various points in the OSI layer, to troubleshoot network issues.
I've been using Wireshark in a number of my posts to show aspects of network performance and to illustrate areas of TCP/IP such as the three way TCP handshake. This week, I thought I'd delve a little more into Wireshark itself and illustrate how the OSI layer works. Two previous posts have shown the TCP three-way handshake (see, for example, my previous post "Using jperf and Wireshark for troubleshooting network issues"), so I will omit covering it in this post.

This is the first in a three-part series on color theory. Warm Colors Link Warm colors include red, orange, and yellow, and variations of those three colors. Red and yellow are both primary colors, with orange falling in the middle, which means warm colors are all truly warm and aren’t created by combining a warm color with a cool color.
Red (Primary Color) Link Red is a very hot color. Red can be associated with anger, but is also associated with importance (think of the red carpet at awards shows and celebrity events). Outside the western world, red has different associations. Examples. Anti-spam Email Link Obfuscator - Mailto: encryption.

This tool was originally conceived and written by Tim Williams of The University of Arizona. The code to randomly generate a different encryption key each time the tool is used was written by Andrew Moulden of Site Engineering Ltd. Ross Killen of Celtic Productions Ltd has also created a PHP version to enable use of this technique in web applications. This code is distributed as freeware, provided the authors' credits etc remain exactly as shown.
Wireshark · Go deep. Ninety Two Years Old and Still Partying! Ninety two years old and still partying! That’s one of the best ways we can describe our friend, Fiorella, whom we have just spent a week ‘partying’ with. So what – you say! What has that got to do with internet marketing?
