Chris Sanders is offering an online Wireshark training opportunity for the rather modest cost of $100. The course will cover analyzer placement on your cabling system, performing a network baseline and troubleshooting network latency.
Are you wanting to get into OpenNMS but are struggling to get started? OpenNMS are running a series of training courses in Europe during May.
The introductory course titled “OpenNMS – A Day in the Life” will serve as an introduction to get you started with OpenNMS.
At the end of the day, you should have a firm grasp on how to get OpenNMS installed, how to discover the network, basic and some advanced OpenNMS configuration options, as well as troubleshooting skills.
The courses are being presented by the head honchos of the OpenNMS universe, so you can be assured that the course will be content packed and authoritative.

JDSU were kind enough to invite myself and Denis to a Test-Um product training day at the JDSU offices in Basingstoke. Michael, the Test-Um trainer, is extremely knowledgeable about cable testing in general (as an ex-installer himself) and about the whole Test-Um range in particular.
One heads up. The Test-Um name is going to start disappearing soon. All of the Test-Um range will be re-branded as JDSU Network and Enterprise Test.
In no particular order, the news from the Test-Um world:
- When toning, ground half of the cable pair if possible in order to increase the tone strength by around 3 times
- Measuring the distance to break using impedance or TDR is only accurate to around 3%. If there’s a break in a cable a tone will generally stop at the break pinpointing it very precisely. However with some of the more powerful toners the tone may breach the break. Using the Banjo cable breakout box, LB68, you can split out each cable and earth them one at a time to detect very precisely where the tone stops and consequently the break. Expect to see the LB68 on our site real soon.
- All of the Test-Um range of tone generators are digital, there are no analogue toners, and asymmetrical, so they do not disturb the traffic even on a live Ethernet network. Although hub flash will also work on a live network it’s sometimes hard to see the flash in among the normal network traffic. Tones are much faster and easier to pick up.
- The Wi-Net can display wireless signal level as both a percentage value and as a dB level. You can toggle between the two quite easily
- An update to the Testifier (to be called the Testifier Pro) is due in the UK in Q1 2008…features to follow closer to launch
We will be discussing a number of these items in greater detail in future posts.
Protocol analysers are difficult tools to master. Though, once mastered you’ll see the pay-off in increased productivity for the rest of your career. Many technologies come and go, but the fundamentals of how networks work changes slowly.
You can slug it out with books but structured learning will help speed things along.
If self paced learning suits you best, a series of four self study courses are available:
- Wireshark Functionality and Fundamentals
- TCP/IP Network Analysis
- Troubleshooting Network Performance
- Wireshark Network Forensics and Security
If you prefer face to face, instructor led learning, that’s available too from the Wireshark Bootcamp. Courses are scheduled worldwide including the London, Munich, Netherlands & Sweden. Courses are scheduled for October so get your skates on! 🙂
