Fun With Wireshark: Introduction!



I haven't used Wireshark in quite some time, so now I had a bit of a re-affilation curve to deal with. How do I know if I'm capturing from my Eth0 interface?

So I pulled up my Network Utility and told it, "Hey, ping my website until I tell you stop."





And it did, and you can see a transcript of the conversation below.




"Hello?" "Hello!"

Step one, complete.

Now, can I be a passive observer on a network and spy on others? Let's see. I joined a hotspot I set up on my LG Stylo called Broadcasting. It's only this Macbook and my iPhone (Remember that?)


Now I try to sniff packets between my iPhone and my Stylo from my Macbook. I keep not getting anything. This page tells me that we should be able to, but I can't seem to snipe it from the air, even being in promiscuous mode.


It's very adamant about having the correct time right now.

I'm going to check out David Bombal's Wireshark course on Udemy.

EDIT 07/12 - I should see if the Xfinity L3 Switch has port mirroring capabilities.


EMPLOYERS: This is me using a variety of technologies (LG with Android, iPhone 8 with iOS, Macbook with OSX (Mojave)) to test network connectivity.

Making KPI Dashboards with PowerBI

 While this is the free tier, I cannot share or collaborate with others, nor can I publish content to other people's workspaces, but they will not stop me from screenshooting and recording these self-taught adventures,so! I'm doing this because I idly searched "Mattel careers" and "Information Technology", and seeing a bulletpoint saying the following: Analytical and reporting skills such as creating dashboards and establishing KPIs such as experience with PowerBI, Cognos, Tableau, and Google Data Lake/AWS is preferred And thought "Well, I've used Tableau, and I've heard about PowerBI,  even if its in-demandness is questionable , so how similar is it? And can I write about it?"  First, PowerBI (PIB) does have a downloadable, local version, but apparently Windows-only. I could download the .exe but I couldn't run it / drag it to applications on my MacBook.  Not a problem, we'll use the online SaaS version, and a dataset found here, ...

Recon and SSID - Mapping With VisiWave Site Survey

My laptop is refurbished. I've written about how there are a few ... quirks. Being a technology professional, I felt okay with adopting an older machine, knowing I had the skill to fix moderate issues. From dying drivers to monitor massacres, I've ID'd, solved, and documented a lot of issues.  The newest one was my Wi-Fi adapter dropping the connection to a specific extender. While troubleshooting, I was curious about doing recon of WiFi networks and broadcasting devices anyway. That issue? A power setting. It was so determined to save power, it would disconnect. The extender is also flirting with the older end of 6 years old.  The battery needs to be replaced, but that's new to me. As a Windows laptop, there are a plethora of options to pick. How do you decide which one is safest?  I am suddenly concerned about this despite having 3 unofficial, 15$ Macbook Air chargers from eBay, and no explosions. But let's move onto the Site Survey - Where can I find the stronges...

S3 Event Notifications Using Lambda

I earned my AWS Solutions Architect Certification in Feb 2026 (🎊) but Like Smash Mouth said, "So much to do...so much to see."  I've used Lambdas that, when an object was uploaded to a bucket, sent a notification to Eventbridge, and then sent me a text and email via SNS. Now, thanks to the free project on Adrian Cantrill's GitHub , I'm going to make a small image processing eventflow. (Emoji use is for fun; Everything here written by a human being.)  What's Happening: Images uploaded to an S3 bucket are made into 5 thumbnail variations thanks to the power of Lambdas and inserted into an output bucket.   Business Use case; If you want to get quick thumbnails.  Maybe this can be scaled out to do file conversion, like .txt to .pdf.  Materials: 2 S3 buckets - one for input, one for processed output. Lambda An image!  Step 1: Bucket Creation  🪣 I made one bucket (runtcpip-source, for images to go in) and copied the settings from it to make the second...
