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.

Connecting IoT Devices to a Registration Server (Packet Tracer, Cisco)

 If you're seeing this post, I'm helping you, and you probably have LI presence: React and share this post to help me in return.   In Packet Tracer, a demo software made by Cisco Systems. It certainly has changed a lot since 2016. It's almost an Olympic feat to even get started with it now, but it does look snazzy. This is for the new CCNA, that integrates, among other things, IoT and Automation, which I've worked on here before. Instructions here . I don't know if this is an aspect of "Let's make sure people are paying attention and not simply following blindly", or an oversight - The instructions indicate a Meraki Server, when a regular one is the working option here. I have to enable the IoT service on this server. Also, we assign the server an IPv4 address from a DHCP pool instead of giving it a static one. For something that handles our IoT business, perhaps that's safer; Getting a new IPv4 address every week or so is a minimal step against an...

Create a Simple Network (Packet Tracer) + A Walkthrough

Again; I've done this, but now there's so many new things, I'm doing it again. The truly new portions were...everything on the right side of this diagram; The cloud needed a coax connector and a copper Ethernet connector. It's all easy to install, turn off the cloud (Weird), install the modules. Getting the Cable section of Connections was an unusual struggle - The other drop down menu had nothing within. It required going into the Ethernet options and setting the Provider Network to 'cable', which is the next step AFTER the drop-downs. The rest was typical DHCP and DNS setups, mainly on the Cisco server down there. The post is rather short - How about adding a video to it? Find out what A Record means - This site says 'Maps a name to an IP address', which is DNS. So it's another name for DNS? You can change them (presumably in a local context) to associate an IP address to another name.

Review: Samsung Galaxy Buds 2 True Wireless Bluetooth Earbuds

  Ah yes, almost 3 years ago, I wrote this review (Despite getting the earbuds for Christmas, I wanted to use them for a few months before writing). And in December of 2023, the right one began to get dull regarding sound. I always make sure they're clean - Ear infections are no joke, clean your earbuds - so that wasn't it, I never got the verification code from Samsung to make an account for them to be repaired, and Samsung Support through chat told me to go to my local approved dealer, a random shop 50 miles away that wouldn't actually give me an estimate. I'd much rather repair than replace, especially if it's a gift. I'll open (or attempt to) the faulty one and look around and still use the other one. So here, let's get some new ones on sale, using a combination of giftcards and luck. I was torn between the colors, but I have, more than once, misplaced the black case and was unable to discern it because...most of my stuff is black. I need a case for thi...
