Wireless Diagnostics on Mac OS; Packet Sniffing on a WLAN


There's a post sitting in my drafts about Wireshark and how to sniff packets out of the air that was going to be about sniffing for authentication packets for Wi-Fi hotspots that aren't broadcasting SSID (Which you shouldn't do apparently! It's still not safe).

I was watching this video to find a little more information about how to properly use Monitoring mode on my Macbook to sniff for WLAN packets on the network.


So when he said "Just open up Wireless Diagnostics and sniff your network (check your width and channel)." It was shocking to me.




Lo and Behold;


If you want this wallpaper, here you go.


The one thing I didn't recognize was Pegatron.

Despite using Wireless Diagnostics, we have to open up Wireshark to actually read the output.


Hewlett Packard - The printer on our WiFi network.
Netgear - The Wi-Fi extender.
ArrisGro - The Xfinity router.

 I looked it up;

Pegatron Corporation is a Taiwanese electronics manufacturing company that develops mainly computing, communications and consumer electronics to branded vendors, but also engages in the development, design and manufacturing of computer peripherals and components. Pegatron's primary products include notebooks, netbook computers, desktop computers, game consoles, handheld devices, motherboards, video cards, LCD TVs, as well as broadband communication products such as smartphones, set-top boxes and cable modems.
My best guess? Pegatron made the wireless component for the Nintendo Switch, which I was playing online for packet research. 

I'll definitely do more work with Wireless Diagnostics in the future.

EMPLOYERS: This shows that I have no problem finding and using utilities already installed, including on Mac OSX (Mojave), to better monitor the business or guest networks I use.

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.

Securing Terraform and You Part 1 -- rego, Tfsec, and Terrascan

9/20: The open source version of Terraform is now  OpenTofu     Sometimes, I write articles even when things don't work. It's about showing a learning process.  Using IaC means consistency, and one thing you don't want to do is have 5 open S3 buckets on AWS that anyone on the internet can reach.  That's where tools such as Terrascan and Tfsec come in, where we can make our own policies and rules to be checked against our code before we init.  As this was contract work, I can't show you the exact code used, but I can tell you that this blog post by Cesar Rodriguez of Cloud Security Musings was quite helpful, as well as this one by Chris Ayers . The issue is using Rego; I found a cool VS Code Extension; Terrascan Rego Editor , as well as several courses on Styra Academy; Policy Authoring and Policy Essentials . The big issue was figuring out how to tell Terrascan to follow a certain policy; I made it, put it in a directory, and ran the program while in that ...
