Non-Linux FOSS: Dive Deep with Wireshark
Before you say anything, yes, I know Wireshark is available for Linux. This time, however, Windows and OS X users get to play too. Wireshark is an open-source network analyzation tool that is really an amazing tool for troubleshooting a network.
Running Wireshark on OS X does require an X11 server (see my Non-Linux FOSS article in the December 2012 issue of LJ on XQuartz.) It also looks a bit dated once it's up and running, but rest assured, the latest version is functioning behind the scenes. If you're thinking this program looks a lot like Ethereal, you're absolutely correct. It's the same program, but six or so years ago the name changed.
Wireshark is strictly a wired-ethernet inspection tool, but if you're trying to solve a network issue, it's the de facto standard tool. It's not a new tool by any means, but if you're on a foreign operating system (that is, not Linux), it's nice to know some old standbys are available. Check it out today at http://www.wireshark.org.
UPDATE: Shawn comments HERE regarding reader frustration/feedback.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy
Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

It appears I may be wrong. I
It appears I may be wrong. I tried for years to get anything useful from a wireless interface with Ethereal, but was never successful. Then a product for wireless ("airshark" I think it was called) was available, so I wrongly assumed wireless just wasn't in Ethereal's bag of tricks.
Cut Shawn some slack!
To everybody bashing this article:
The section "Non-Linux FOSS" has had short articles in the past. Nothing new.
And do you remember when you were a rookie at Linux? I do, and that was 2 years ago. I've known about wireshark before I started using Linux, but maybe somebody else is just starting out and never knew about Wireshark until reading Shawn's article. By him even 'mentioning' these programs can help people find what's out there in the real world to help them. Shawn has helped me TREMENDOUSLY with his articles ever since I've used linux, and it's nice to know that these programs also exist for other O.S.'s too. He may have been wrong about the wireless part, but we all make mistakes. Give him a break!
Shawn, keep up the great work! As always, your articles kick ass!

Hasn't Wireshark been
Good post and thanks for sharing this!
Carlie is sure nice to look
Carlie is sure nice to look at!
Shawn busts his ass writing
Shawn busts his ass writing articles for lj. Simmer down, trolls.
yeah Shawn
And your hair is funny looking too.

So...
I've apparently poked the bee's nest here...
1) "Dive Deep" is a play on the word "Shark" -- perhaps it was misleading, but the intent was nothing more than to play off the product name.
2) The point of the "Non-Linux FOSS" posts is to give Windows/Mac users a little glimpse into the world of Open Source. Sometimes I pick Windows-only programs, sometimes I pick something available cross-platform.
3) When I say it's a wired-only, I meant as opposed to wireless, which is the most common question I get about Ethereal (Wireshark). Perhaps I should have clarified my meaning better, my bad.
4) If I "dove deep" with an article intended for a Windows audience (again, refer to point 2), I'd get tarred and feathered.
All that said, thanks for the feedback. My intent wasn't to bamboozle anyone. :)

So 802.11 wireless is not wireless?
"3) When I say it's a wired-only, I meant as opposed to wireless, which is the most common question I get about Ethereal (Wireshark). Perhaps I should have clarified my meaning better, my bad."
Since, according to the webpage posted, Wireshark on Linux, Windows, and Mac OSX supports sniffing 802.11 Wireless LAN, how is that possibly "wired-only?"
I may be absolutely wrong here...

So while it appears I was incorrect, I can say, "I've only ever had luck using it as a wired-ethernet tool, YMMV."

deep dive ?
as everyone else i totally agree on this... what a joke !
hey, today is april 1st and no one told me :(
Seriously? Is this, like, a
Seriously?
Is this, like, a placeholder for an *actual* article on Wireshark?
HEY EVERYONE!!! Here's a "deep dive" on Ubuntu:

Check it out at www.ubuntu.com
Wireshark: "Deep Dive"??
Shawn, Shawn, Shawn . . . I'm surprised & disappointed!! Even I, a 62-yr. old 'hacker-wanna-be' (can't be...time constraints: got 2 ea. teenagers!!) know *better* than this!! Next time you've had one too many, or simply need time off --- take the day off!! Even I know wireshark is capable of more than "strictly a wired-ethernet inspection tool..." I've been reading your pieces since about the mid-1990's and you are more resourceful than this!! Re-make this sandwich, and put some meat on it!
Take Care. Have A Healthy, Prosperous Day!!

the thing is that i expected
the thing is that i expected too something more about this program. I am sure that there's more of this kind if you google it.
What a waste of a mouse click...
I agree with most of the posters - I was hoping to see something about filters and all the other protocols it supports - even RTP recording! No mention of any of this. Stop sending SPAM to increase mouse clicks to your site...
Lost in translation ...
Got this from my RSS feed and was expecting a "a dive deep" review of wireshark but all I've got was:
1. A screenshot
2. A link to wireshark website
Thanks to Linux Journal for wasting our time ...oh btw: my niece can do a much better job if this kind of quality goes into LJ. where the heck is the editor anyway ?
It's for more than just wired ethernet
From http://wiki.wireshark.org/CaptureSetup/NetworkMedia, Wireshark on both OSX and Windows supports Ethernet, PPP, 802.11 Wireless LAN, and VLAN. On Mac it supports loopback (Windows does not have), and on Windows it supports Tokenring.
Of course, on Linux, it supports ATM, Bluetooth, CiscoHDLC, Ethernet, FDDI, FrameRelay, IrDA, PPP, TokenRing, USB, 802.11 Wireless LAN, Loopback, VLAN Tags
So it is NOT "strictly a wired-ethernet inspection tool" - not by a longshot.
misleading title
Why is this titled "Dive Deep...". I came here expecting some cool things you could do with wireshark. Filters and such. This is worthless.
Hasn't Wireshark been
Hasn't Wireshark been available for Windows for years?
Yes. Yes it has.
Yes. Yes it has.
I thought so, I recall
I thought so, I recall experimenting with it.
This article makes no sense at all, I think someone accidentally posted a draft article.
really?
Thanks for spending 5 minutes posting a screenshot and URL for Wireshark, that was really worthwhile.
