NetBeez Quickstart (by Tony Fortunato)

There is no shortage of utilities, applications and full blown network troubleshooting systems out there.  Some are free, and some cost a pretty penny.  Spoiler alert, they ALL have their place in the analysts’ toolbox.

When I present or work with a client, I explain the tools only accounts to 50% of the equation to successfully fixing a problem.  The other 50% is split between knowledge and practice. Think about it for a moment, anyone can buy a pocket knife, but only a few of us can carve something recognizable out of a block of wood.

NetBeez provides a very helpful free version of its product so you can get a feel of what it can do and where it might fit into your specific environment.  In the past I would have to figure out how to schedule, report results and then compile them for a report. Any one of those challenges would immediately turn off most analysts since we have plenty on our plates already.

Look at good old ping for a moment. Sure anyone can ping something

I tested the free virtual appliance, which you can find here https://netbeez.net/product/plans/netbeez-free. The free version supports; one agent, three targets, 1 user, Cloud server account, SMTP alerts, 1 and week data storage which is plenty for me and some of my clients who tried it.

Setup is pretty simple, go to NetBeez and create a cloud account and download their ova file. I used VMWARE workstation with no issues.

Some of the measurements that I tested are:

  • PING, Packet Loss, Round-Trip Time,
  • TCP-based PING test, Round-Trip Time, Packet Loss, Custom port numbers

Venus, Mars and the Frontal Lobe (by Paul W. Smith)

Lobes of Human Brain

Men and women are different.  Whether this is obvious or controversial depends on your point of view, but it’s just true.  Most of us can accept this based on personal observations.  One of my favorites is the Cocktail Party Test.  When two women meet at a party, the first question will nearly always be “Do you have any kids?”  For men, it will be something like “Did you see the Broncos game last night?”  There are plenty of other ways to separate men and women, but this one is bulletproof. 

By the time my wife and I passed our tenth wedding anniversary, I was starting to grasp some of those other ways.  This was around the time that John Gray’s bestseller, Men are from Mars, Women are from Venus started its run to becoming a bestseller.   The national conversation turned to differences in thinking and communications styles that divide the sexes.  Many will be familiar.  Take personal care for example; women search for a hair product with protein, aloe extract, volumizers, vitamins, minerals and liquid keratin.  Men look for a bottle that says “shampoo.” 

For some reason, scientists weren’t willing to settle for cocktail parties and shampoo.  SPECT (Single Photon Emission Computed Tomography) is one of their many brain imaging technologies that can monitor blood flow and activity under various stimuli.  A recent study using this approach looked at 46,000 images of healthy men and women as well as some folks with an assortment of psychiatric conditions.  The researchers were surprised to find that men and women really are different.

Wireshark Dropped Packet Counter (by Tony Fortunato)

I'm keeping this one nice and short.  shorter than my regular short posts  ;)

For those of you who read my material regularly, I’m sure you will remember me referring to ‘baselines’ and ‘tool calibration’ exercises. 

The point is for you to take a closer look at your tools or applications and understand how they behave and in some cases what changes version changes may bring.

In this specific example I was working with Wireshark and noticed the ‘dropped’ packet counter is missing from the status bar and found it elsewhere.
