Office War 3 - Nerf Armageddon

This is one of those video's that you watch on Saturday, but can't wait for it to be Monday to show everyone in the office. I'm not sure that there will ever be a more amazing NERF War ever recorded (however I won't be disappointed if I'm wrong).

Windows Window Management or Eazy Resizing

Recently I was lucky enough to come across a great deal on a 24" monitor that I could use for all of the network design work (Visio deserves at least 24") that I have been doing recently. In addition, I wanted the screen real estate so that I could have numerous terminal sessions open as I am usually logged into 4-8 devices at a time. However, resizing windows to take advantage of all of this space is time consuming, boring, and inaccurate. I found a tool called Ponderosa in my previous searches that would allow for me to have multiple sessions open and resize them individually however it didn't quite have everything I wanted in a terminal program (I like SecureCRT or Putty) and it couldn't allow me to resize other applications.

Lucky for me there is such a FREE tool out there and it is called WinSplit Revolution. It is an amazing tool and has easy quickset keys based on the number pad that allow you to resize or maximize windows individually and tile them however you want. As if this wasn't enough, it even support for multiple monitors so you can quickly send an application to another window.

I highly recommend this program if you have lots of screen to put to use or have lots of applications open that you want to tile.

Cisco Discovery Protocol (CDP) for your PC

At my previous job I once saw an Engineer walk around with a Cisco 2500 router when he would go out to work on an end users network port. He used this to identify which switch and port that user was connected to by doing a show cdp neighbors. After that I remembered that I had seen a Linux module that allowed you to capture and decode CDP messages however not everyone runs Linux and Windows is much more common. To that end here is an open source project that runs not only on Linux, but on Windows as well.

You can find it on SourceForge here: http://sourceforge.net/projects/cdpr

It runs from the Windows Command prompt and when invoked lists your Network Adapters so that you can select which interface you would like to monitor for CDP messages. When a CDP message is recieved (and remember the default for CDP is 60 seconds so you may have to wait a bit) it will decode the message and display the neighbor information.

This is a great tool which sure beats having to go out and get a MAC address and track it down through several different switches.

Juniper Enterprise Switching Certification - FREE!

Last year Juniper started a program called FastTrack to help people who had certifications from other vendors (read Cisco) obtain the equivalent Juniper certification. The first test was the Juniper Networks Certified Network Associate - M/T series (JNCIA-M). The only catch is that you first have to pass (70%) an assessment test which you can take as many times as you want. After you pass the assessment they email you a voucher for the real exam. Once you pass the real exam, you can take the assessment for the JNCIS-M. Additionally when they launched their Enterprise Routing Certifications the same process applied. When the test first launches the vouchers are for 100% of the cost and a few months later they change them to 50% off which is still a great deal. Additionally, they give you all of the coursework that you would get as if you were taking the instructor led classes so you have study material to help you pass the tests.

NOTE: The voucher program for the JNCIA/S M/T series is no longer available

Recently, Juniper launched their new series of Mulitlayer Ethernet Switches and are now offering the Enterprise Switching as part of the FastTrack series. The voucher is good for 100% of the cost of the test if you pass the assessment by August 31st.

You can read more about the FastTrack program here:

You will need an access card to register which you can get here:

Special Thanks to BJ Hoskins for pointing out this new addition to the program.
