Sniff Smarter, Not Harder: Why Wireshark Preferences Are Your Secret Weapon

Before you even think about hitting that capture button in Wireshark, spending time in Edit → Preferences is one of the smartest moves you can make. Out of the box, Wireshark is powerful—but it’s also generic. Every network is different, every investigation has a purpose, and default settings rarely align perfectly with your environment. By configuring preferences first, you’re essentially tuning Wireshark to your network, which means cleaner captures, better visibility, and less time wasted digging through irrelevant data.

One of the biggest advantages of tweaking preferences early is improved capture and file management. Wireshark relies heavily on heuristics and default port assumptions to identify traffic. 

Making the most of Lab work

 One of the biggest challenges technical staff face is trying to get the 'ok' to do lab work.  And in managements defense, (and from I've observed in my career,) staff rarely properly document why they need lab time and what the benefits are.

Management imagine technicians tossing paper balls into the trash can, gaming and generally goofing off during this time. I should know because I was in management and have actually seen this exact scenario play out. It only takes one time to ruin for everyone asking after you.

Do yourself and your boss a favor and try to take a more organized approach to requesting and reporting on your lab work.

Now for a little fun.. lovemytool is alive!!

 

Big news in the lab, folks: the legendary LoveMyTool name is back in action! After years of living under the slightly more buttoned-up banner of The Tech Firm Blog, we’ve decided it was time to bring back a name with a little more personality… and let’s be honest, a lot more attitude. Because nothing says “serious technical insights” quite like a name that also sounds like it belongs on a novelty coffee mug.

This revival wouldn’t have happened without the generosity of Tim O’Neil, who kindly handed over the lovemytool.com name so it could live again. That means if you punch in www.lovemytool.com , you’ll land right here at https://thetechfirmblog.blogspot.com great content, same questionable humor, just with a name that feels like it’s wearing a Hawaiian shirt instead of a suit and tie.

For longtime readers, this is a bit of a homecoming. The original LoveMyTool blog built its reputation on mixing solid technical know-how with a wink and a nudge, and plenty of you have made it clear that the name was half the fun. So consider this the best of both worlds: the same blog you’ve been reading, now rebranded with a name that reminds us not to take ourselves too seriously—even when we’re deep in packet captures or arguing with firmware. Welcome back to LoveMyTool. 

Yes, I missed it too.

What Caused the Microsoft Developer Account Lockout?

 The Microsoft developer account lockout incident described in the article highlights how several major open-source security tools—including VeraCrypt, WireGuard, and Windscribe—were suddenly cut off from distributing updates to Windows users. According to the report, developers found their accounts suspended without warning, preventing them from signing drivers or releasing patches. Because Windows requires signed drivers for installation, this effectively froze updates for tens of millions of users, leaving them potentially exposed to unpatched vulnerabilities.

The root cause appears tied to Microsoft’s Windows Hardware Program and its mandatory identity verification requirements. Developers were expected to submit government-issued identification within a set timeframe, but several affected maintainers they never received proper notification—or even completed verification without regaining access. 

How to Solve the Four Most Common Problems with PoE++ Devices (Julio Petrovitch)

In 2018, the IEEE 802.3bt (PoE++) standard for Power Over Ethernet was approved. It offered more power, allowing devices like high-powered security cameras to be run on PoE. Which is great – until the installer uses the wrong cable to connect a camera and can’t figure out why it won’t power on.

Having multiple standards makes troubleshooting PoE issues more complicated. For example, many field technicians or network engineers don’t realize that upgrading to new pan-tilt-zoom cameras or to Wi-Fi 7 access points with multiple radios will require a PoE upgrade as well. As offices and warehouses deploy more smart devices that need PoE++, testing becomes more important. This article will explain the PoE++ standard, best practices in PoE deployment and testing, and how to solve several common problems.

What is the PoE++ Standard?
