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.

Contactless Tech’s Role in the New Guest Experience ft. Intelity and The George

 Contactless hospitality technology is growing. You want to get away, and you'll be damned if a little thing like a deadly virus will stop you! But you still don't want to touch things. Ew. During the chat between INTELITY CEO Robert Stevenson and THE GEORGE Director of Operations Kerrie Hunter, you’ll learn how the historic boutique hotel has adapted a mobile-first guest experience in the wake of COVID-19—and how they see contactless technology affecting the future of hospitality. I don't remember how I found INTELITY (probably hoping to score a position with them), but I liked them enough to stay on the e-mail lists.
