What's that smell? It's Packets!

A detailed look at the Wireshark protocol analyzer

Greetings, In this article I want to discuss the other powerful tool a systems administrator should know about. It is called Wireshark (from Wireshark.org). Wireshark is in essence a sniffer, in that it can listen in on the packets on the wire and tell you whats what. Officially its called a protocol analyzer which is more true to its mission. In this article I want to share with you a few items of value about Wireshark, and why you should get to know this tool better.

I think that as technical people we get lulled into a dull sense of safety with tools, for example a reliance on a control panel tool that identifies bad guys by their actions and blocks their IP's. This is for sure a good thing, but it is not the only thing. With tools like Wireshark, we can peer into the activity of our server and see what is going on at the packet level. A client some months ago came to JoomlaRescue.com and was having a problem with continually being hacked. We tracked it down to a compromised (vulnerable) FTP software that had allowed them in. However we found they were using FTP through the use of Wireshark.

This is important because if you were unfortunate enough to have a bad guy insert this INTO your network he could eavesdrop on everything you do. However - in this use case, it is being demonstrated as diagnostic tool.

For the purposes of this article I ran Wireshark on MY personal machine only. It was never allowed outside my network, so in other words, everything you see here came to my machine using normal, everyday browsing techniques.

How to Add CSS/Javascript to Your Joomla Extension

This article applies to Joomla! 1.5 development. This information is subject to change in Joomla! 1.6.

When writing your custom component or module, more often than not, you will want to include your own CSS or Javascript code. If Joomla! did not provide an easy way to do this, you would be forced to use script tags throughout your code. While this approach would technically work, the best practice is to put all scripts inside the head tag of your page. How is that possible when the of your page is only seen on your template index.php file and you're developing a new module or component? The JDocument class is the answer. Let's look at the easiest way to go about doing this.

Joomlashack University Reopens Today

In October 2009 the new Joomla training course - Joomlashack University opened its door to its first class of 100 students. For the last 4 weeks, these students have been learning how to Joomla with our rich video screencasts and tutorials and asking questions and networking in our forums.

Before launching Shack U, we knew we had a great product to offer. We gave leading Joomla figures a sneak look at the content and, as you can read yourself, they loved it.

As well as teaching insider Joomla tips and tricks to our first students, we have been taking feedback and improving the course. We have streamlined the student path through the learning content and added more courses.

After 4 weeks, we are ready to open our doors again.
