Mercury Reader For When you Need To Read (by Tony Fortunato)

I find myself constantly reading, referencing and searching for information for all sorts of reasons.

It can get difficult to focus on the information when you have advertisements blinking and videos playing. Then then are those websites that provide good information but their download button downloads the entire document, not just the article you were reading.

This is where Mercury Reader comes in. This is a free Chrome extension that will render and reformat the page in a much easier to read format.

In this video I cover what happens if you try to use Mercury Reader on a page that does not have an article on it as well as when it works well. As I mentioned in the video, double check that Mercury Reader gets everything the first time you use it. After you render the page, you can print to your printers or to PDF if you want to save it for later reference.

Layer 1 Troubleshooting Scenario (by Tony Fortunato)

In this article I wanted to review a current troubleshooting scenario that I thought you would benefit from.  The point of the article is that you should never overlook the basics.

While working onsite, I overheard a group of technicians discussing a current issue with a WiFi radio on a tower. Their management system reported that the radio was down and probably had to be replaced. One of the issues is that they have to get a hold of someone to climb the tower which means that the outage only gets longer. After they located someone I asked what was going on.

The senior analyst explained that his happens every so often and the radio just needs to be replaced with a new one.  I then asked if they would mind showing me around since we were just waiting for the contractor and they said no problem.

We walked over to the bottom of the tower, opened the enclosure and noticed that smell of burnt popcorn. There obviously wasn’t any popcorn there, that’s just my way of describing the smell of burnt cable or electronics. After some poking around, I determined that they needed to replace a lot more than just the radio.  In the video, I explain what I looked for, what I found and what I suggested. 

While waiting for the contractor, i also suggested that we review their grounding.

Testing POE with Pockethernet (by Tony Fortunato)

Its important for analysts to have basic tool to test their equipment and cables.

The other day I needed to replace a POE injector on a roof and wanted to make sure that the one I found in my box of goodies actually works.

I’ve been in many situations where the equipment or cables I find in a box is there because it doesn’t work.

So I used me pockethernet (www.pockethernet.com) to test the link, poe and network connectivity and thought I would share.

Having layer 1 test tools is not optional for me since I cant tell you how many issues I resolved that were at layer one.

Using Microsoft’s clip (by Tony Fortunato)

In this video I demonstrate an oldie but a goodie, how to redirect output that normally appears on your screen to a file. I take it a step further and show you how to append to the file as well.

These are great tips if you want to put ping, tracert and other commands into a batch file and schedule some testing after hours.

The only disadvantage to this is that you may end up deleting several files if all you do is put those contents into another file.

In this case you can use Microsoft’s clip command to put your output directly into the clipboard, so all you have to do is paste the contents into your document.

Real straight forward tip that will save you some time when you’re troubleshooting at the command prompt.

ProfiTap's Network Superheroes (by Tony Fortunato)

ProfiTap contacted 12 network analysts and had them put their ProfiShark product through its paces. Then the analysts wrote about their specific experiences, feedback and general thoughts.

I read through the pdf's and was intrigued as to what people wrote about and enjoyed hearing from different perspectives.

I personally think the end result was a great mix of articles that i think you would enjoy.

Here's a very brief summary along with the links:

Mike Pennacchi “Measuring Device Latency with the ProfiShark”

  • Mike shows us how to use the SPAN mode of the ProfiShark while determining and comparing the latency introduced by a Microtik configured to use NAT.
  • Very cool to see Mike sharing the methodology behind his testing.

Stuart “Thor” Kendrick In-line Tapping in the Data Center”

  • Stuart takes us through his trials and tribulations while adding another VLAN to an ISILSON cluster.
  • Impressed with the level of detail and photos Stuart provides walking me through ProfiShark Manager and his specific connects.
  • Liked that Stuart used another tool ‘mass-ping’ for his troubleshooting.
