Wireshark’s new tool – Transum (by Tony Fortunato)

I’ve been playing around with TRASUM for a year or so and got excited when it was announced that it is now included with the current Wireshark build. No more downloading, putting the files in the correct folder, etc..

Transum is a pretty helpful addon since it provides protocol various statistics in your trace file.

In the video below I provide a quick rundown of how to enable it, configure and use it. Once you get playing with it, you will see its immediate benefit.

Here’s the two links I reference in the video to make life a bit easier for you.

Wireshark Decode As Feature (By Tony Fortunato)

Wireshark does a great job Identifying, Decoding, Dissecting and presenting packets and their associated packets.

Every so often you may find that Wireshark doesn’t figure out the protocol and leaves you with a bunch of TCP or UDP packets.

In this video I show how to quickly teach Wireshark what the protocol should be.

Even if you don’t know the protocol, you might be able to look in the Bytes pane to figure out what it should be.

Enjoy.

How to Reset a Cisco 3750 To Default Factory Settings (by Tony Fortunato)

As a consultant/contractor I usually run into the following scenario where I’m given equipment to configure and it currently has a password. Even though I know the answer, I still ask if they know the password. After several tries of what it should be, I give up and ask if I can reset the device to default and start from scratch.

Over the years I have gone through the process countless times with as many vendors. Some procedures are as simple as holding a reset button and others are complicated that involve calling the vendor for a challenge/response.

Cisco has variations on their reset procedure but mainly consistent which makes it fairly easy. In this video I will show you how to rest a Cisco 3750 switch to factory settings.

Tonys bits – Simple IP Config (by Tony Fortunato)

I have been getting a lot of requests to share the software that I use in my classes and in the field, so here we go.

This one is called Simple IP Config. Pretty straightforward software where you create different network profiles that you would need in your environment.  For example you might need a static IP address to configure equipment for the first time.  Or you might need a static IP address for certain networks.

The software is free, has no ads, portable, so nothing to install and lastly, it just plain works well. You can find it here; https://sourceforge.net/projects/simpleipconfig/

Depending on your configuration, you may need to run the software as an administrator and leverage the fact that it uses plain text ini files to further customize.

Saving Specific Packets With Wireshark (by Tony Fortunato)

I’ve received a few requests to update some of the Wireshark basic skill videos since the user interface has changed in version 2.

I just got an email from a new Wireshark user asking how to save packets that result from a display filter.

In this video I cover that procedure and look forward to creating more updated videos
