Filter Like a Pro: How Wireshark Display Filters Save You Hours of Headaches

 If you’ve ever opened Wireshark and stared at the endless flood of packets flying across your screen, you know it can feel like trying to find one drop of water in a waterfall. That’s where display filters come in. Learning how to use Wireshark display filters — especially for things like narrowing traffic down to a specific IP subnet — is like flipping on a spotlight in a dark room. Instead of drowning in packets, you can instantly zero in on exactly what matters.

In my latest video, I walk through how to create and use a display filter for an IP subnet. This simple trick saves tons of time when troubleshooting network issues. Instead of scrolling endlessly or exporting data to another tool, you can just type something like ip.addr == 8.8.8.0/24 and immediately see all the relevant packets for that network. It’s fast, it’s clean, and it keeps you focused on solving the problem instead of searching for it.

The more you get comfortable with display filters, the more powerful Wireshark becomes. You can combine filters, exclude noisy traffic, or even isolate specific conversations between devices. Once you start using them, you’ll wonder how you ever managed without them — it’s like going from a shovel to a laser scalpel for your packet analysis.

So, if you’re looking to save time and actually enjoy using Wireshark, start learning display filters today. They turn what could be hours of frustration into minutes of precision. Check out my video to see exactly how I use an IP subnet filter in action — and you’ll never go back to staring at unfiltered chaos again.

Nailed it.. ;) - an Exercise in supporting our colleagues

 An excited reader sent this photo.

Since he is new to the field, i had to politely and constructive explain all the ways to 'make this install better'.

after an email or two, i could se that he was pretty laid back and i casually said "other than that one grey cable, you nailed it" and we have a good chuckle..

I also mentioned that no matter what, you can never have enough documentation and labels.

I finished off by saying "put yourself into troubleshooting mode, and ask yourself how easy it would be to trace a cable" ,  "then put yourself into installation mode and ask yourself how easy is it to install a new piece of equipment".

He thanked me for being an "awesome mentor".

I replied that I dont consider myself much of a mentor but appreciated the kind words.

And then he mentioned something that was a bit disturbing to me.  He said that he reached to about half a dozen people who post on Linkedin/Youtube and I was the only one who responded.

C'mon folks, we can do better.  I know we are all busy..  But it doesn't take much for a quick response, even if its "I don't know, but try this".  this email exchange took about 10 min of my day.

From the net: How to Simulate Network Outages

Simulating network outages is an important step in validating highly available and/or redundant network configurations. Along with validation, another use case for simulating network outages is to test the resiliency of mission-critical systems and applications. The simplest example of a test-driven network outage is to turn off the primary uplink connection of a dual-homed router and analyze the results. With appropriate tools, you can verify that the network traffic quickly re-converges to the secondary link with minimal packet loss. In more complex scenarios, the network simulation may need to introduce packet loss, increase in round-trip time, bandwidth saturation, DNS and DHCP failures. To implement these failure scenarios there are different tools that can do the job. I’ll briefly review some of them, particularly the open source solutions.

Why Every IT Troubleshooter Should Carry a Portable LCD Display

 

When you’re deep in the field troubleshooting hardware or network equipment, one tool that often goes underappreciated—but can save the day—is a portable LCD display. Many devices such as servers, switches, or embedded systems output critical data or BIOS messages directly to a display, and without one on hand, you might find yourself blind to what’s really happening. A compact LCD lets you instantly see console outputs, error codes, or configuration prompts without waiting for someone else to bring one or trying to guess what the LEDs are telling you.

Portability is the key advantage here. Modern LCDs are lightweight, slim, and powered through USB or battery packs, making them easy to slip into your toolkit or backpack. When you’re on-site, especially in tight server rooms or industrial areas, you don’t have the luxury of hauling a full monitor around. Having your own display means you can plug in, verify, and get results fast—whether it’s a headless system, a router with a misconfigured interface, or a piece of lab gear showing diagnostic information.

Carrying your own display also means independence and preparedness. You’re not relying on the client’s equipment or waiting for someone to find a monitor in a dusty back room. You can confirm system states, troubleshoot POST issues, and even make quick BIOS or bootloader changes on your own terms. It’s a small investment that pays off big in time saved and professionalism demonstrated.

In short, a portable LCD display transforms how you handle unknown or unresponsive systems. It’s like having an extra pair of eyes in your toolkit—ready whenever the situation turns unpredictable. Whether you’re configuring switches, diagnosing embedded devices, or recovering from boot failures, this one tool keeps you in control and keeps your troubleshooting momentum going strong.

blast from the past: The IBM 3800 Laser Printer

 

The IBM 3800 Printing System, introduced in 1976, was a landmark in computer printing technology and is often regarded as the world’s first commercial laser printer. Designed primarily for high-volume data centers, the 3800 combined a laser imaging system with electrophotographic technology (similar to photocopying) and continuous-form paper feeding. It could print at an impressive rate of 20,000 lines per minute—roughly equivalent to 110 pages per minute—making it a revolution in automated document generation for large organizations like banks, insurance companies, and government agencies.

When it first launched, the IBM 3800 came with a hefty price tag. Depending on configuration and options, the system cost between **$250,000 and $500,000 USD** (equivalent to over $1 million today). However, IBM typically leased such machines to clients rather than selling them outright. This business model made sense for large-scale enterprise operations that required regular maintenance, consumables, and software integration. The printer’s cost was justified by its efficiency—it could replace multiple impact line printers and drastically reduce downtime and operating costs in large-scale print operations.

The 3800 also introduced several important innovations in digital printing. It was the first printer to take input directly from digital computer data, rather than relying on preformatted line print files, allowing for dynamic page layout and improved typographic control. The printer supported fonts and graphics stored in memory, a feature that paved the way for later desktop laser printers in the 1980s. Its use of continuous-form paper and integrated fuser technology made it highly reliable for round-the-clock operation, which was essential for industries producing daily billing statements or reports.

As for trivia, the IBM 3800 was so large it required its own dedicated room and environmental controls—it resembled more of a small car than a modern printer. It was also one of the first machines to use a **laser beam controlled by computer logic** to create images on a photoconductor drum, a concept that later became standard in laser printing. IBM continued developing the series through the 1980s, leading to successors like the 3800 Model 3, which improved resolution and reliability. Interestingly, some units remained in use well into the 1990s, a testament to their engineering quality and durability. The IBM 3800 is now remembered as the ancestor of modern laser and page printers, marking a major milestone in the evolution of digital printing technology.

Passive Discovery with Wireshark: Finding Devices the Safe, Quiet Way

Wireshark is an ideal tool for passive device discovery because it listens without touching the network — no probes, no ARP scans, no extra traffic that could disturb production systems. When you capture traffic at a mirror/span port or on an access point, Wireshark reveals the network “chatter” devices already send: discovery protocols (CDP/LLDP), DHCP exchanges, ARP, mDNS, and more. In your example, capturing a CDP packet from a Cisco switch instantly gave you device-identifying information (device ID, platform, capabilities) and the management IP address advertised in the CDP Address TLV — all without logging into the device or changing network state. That makes passive discovery low-risk and stealthy, especially useful in sensitive or stable environments where active scanning is unacceptable.

Beyond safety, passive captures give richer context than simple ping sweeps. A single CDP/LLDP frame can include the switch model, root/neighbor relationships, VLAN and port identifiers, and the management address — data that helps you map topology precisely. Wireshark’s decoders present those TLVs in human-readable form and you can quickly build an inventory: which switches are where, which devices advertise PoE capabilities, and which ports connect to what. Because you observe real traffic, you also learn about timing and frequency (how often devices advertise themselves), and you can correlate discovery with DHCP or ARP to see which IPs correspond to which MACs and which clients are actually active.

Finally, passive discovery with Wireshark aids troubleshooting, security and forensics. If a new, unexpected device appears on the network you can inspect the capture to see how it identified itself (hostname, vendor OUI in the MAC, CDP/LLDP info), whether it requested an IP via DHCP, and what services it announced. That speeds incident response and root-cause analysis. A short practical tip: apply display filters like `cdp` or `lldp` to quickly find discovery protocol frames, and expand the Address/Device-ID TLVs in the packet details pane to copy the management IP shown in the CDP packet. Always remember to capture only where you’re authorized to and respect privacy and policy when monitoring networks.

I LOVE Network Testing Ep 8 - Beyond Wire Map Testing. Understanding Qual, Cert, & Bit Rate Testing for Copper Networks

Trust, But Verify

 No matter how clear your instructions are, there’s no substitute for being physically onsite when IT work is being performed. In this case, even after repeatedly confirming with the vendor that the switch they were to connect to was PoE+ capable, they still went ahead and installed multiple PoE injectors—consuming valuable rack space and unnecessary AC outlets.. This kind of oversight highlights a simple truth: communication alone isn’t enough when it comes to critical infrastructure. Seeing the work firsthand ensures what’s being implemented aligns exactly with what was planned.

Being onsite gives you the opportunity to catch issues in real time before they become embedded problems. A quick glance at the rack would have immediately revealed that injectors were being installed, allowing for an instant correction instead of discovering it later.

37 INSANE Linux Commands you NEED to Know in 2025

Communicating - Paul W Smith

 

I know you think you understand what you thought I said, but what you heard is not what I meant.

This phrase, sometimes attributed to former Fed Chairman Alan Greenspan, nicely captures the problem we often have in communicating. Getting our ideas across to another goes far beyond just articulating them clearly - it involves a subtle combination of body language, volume, emphasis, cadence and inflection. It benefits tremendously from continuous feedback. As text messaging and social media become more frequent communication channels, it’s easy to see how we might have trouble understanding one another.

When my wife and I travel internationally, we try our best to learn a few basic phrases in the local language. At the very least, it’s a polite way of acknowledging that we are on their turf. It is usually met with a genuine effort to find some common ground for exchanging information. I am embarrassed by the number of people around the world who speak functional English, while my foreign language skills are minimal at best. In these conversations, facial expressions and gestures are a critical element of success. This approach, however, isn’t always enough.

Recently, we were in Budapest and my attempts to learn a few words in the Hungarian language were a complete failure. When a store clerk, who had just been speaking fluent Hungarian to his colleague, thanked me for my purchase in nearly perfect English, I asked him to teach me to say “Thank you” in Hungarian. After about 5 attempts, I gave up, apologized, and walked away in defeat. Several days of study and practice later, I tried out my new language skill on a local tour guide (who BTW also spoke excellent English). “Köszönöm,” I said. After giving me a quizzical look, she finally replied “I think you are trying to say, “Thank you”?

Sensing my frustration, she added that Hungarian is considered one of the most challenging languages to learn. While she didn’t say how long it had taken her to learn English, she did point out that there are many different dialects in the US, making it difficult when speaking with tourists from different regions. But even when speaking the same language with someone from the same region, we still find it difficult to communicate. As if that isn’t enough, even those troublesome dialects shift with time.

If you are a “Swiftie”, you will recognize the picture above. If not, you do now. Tay-Tay fans will also know that she began her career at age 15 when she signed a deal with Big Machine Records. At the age of 16, she played a concert ($20/ticket) at Athens Drive High School to an audience of about 150 students. Whether you're a Swiftie or not, you've likely heard about her recent Eras Tour, which began at State Farm Stadium in Glendale, Arizona. The sold-out stadium held 69,000 people. The average ticket price for the Eras tour was $1600.

According to speech scientists, more than just Ms. Swift’s artistry, fame, and bank account have changed. Researchers Miski Mohammed and Matthew Winn at the University of Minnesota have studied years of interviews with Taylor Swift to trace the evolution of regional and socio-cultural dialects. Taylor is a very public figure, and her numerous media appearances spread over a 20-year year career provide an exceptional opportunity to chronicle dialect change for an extended period of time. Mohammed and Winn’s results were recently published in The Journal of the Acoustic Society of America.

Acoustical measurements and analysis captured changes in accent from her country phase in Nashville, through her transitional period in Philadelphia, to her New York pop era. Her Southern indicators faded as she moved to Philadelphia and New York, with her pronunciation even showing signs of hyper-correction from the preceding dialect. The change was accompanied by lowered pitch associated with authority and confidence. This was a time when Taylor was becoming more outspoken on social issues. In summary, the study suggests that speech patterns and accents are determined by a combination of geographical location, social dynamics and personal development.

Traveling in foreign countries has helped me to appreciate just how much I take communicating for granted. Learning a few words in the local language can help, but “köszönöm” won’t get you very far. It’s easy to take communication for granted here in the US, but even a common language has it’s pitfalls. Effective communication involves more than just words - it involves tone, body language and feedback. Even when speaking the same language, varying dialects and accents complicate communication. Taylor Swift’s evolving speech patterns, studied in depth by researchers, demonstrate how geographical location, social dynamics, and personal growth influence dialect change.

If we ever hope to understand what others say and mean, it’s clear that email, text messaging, teleconferencing (with postage stamp sized head shots) and other social media channels are not the answer.

Wireshark, Kali and nmap exercise

 I get quite a few emails of people asking me for troubleshooting tips and tricks as well as assistance with problems.

I wish I had a dollar every time I suggest people get familiar with their tools, play with them, and determine their limitations with specific tools. You wouldn’t troubleshoot a cabling issue with Wireshark, would you?

What would you think about a baseball player not going to the batting cage and expecting to play in the major leagues, or a hockey player who refuses to go to hockey boot camp or practice.

The funniest thing, is that you do not need a fancy lab and a lot of equipment for your exercises or to practice.  You can take most tasks that you do every day and turn it into an exercise. 

Here are some examples that I perform almost daily to keep my skills relatively sharp.:

-          just start a Wireshark capture

-          review a trace

-          ping something, trace route while capturing

-          look at my ARP table in Windows or Linux

In this video, I use Kali Linux and Wireshark and nmap to illustrate an example of a simple exercise you can perform as well.

A Breath of Fresh Air Why Blowing Out Dust Keeps Your Computer Alive Longer

Dust may seem harmless, but inside your computer, it’s a silent killer. Over time, tiny particles build up around fans, vents, and heat sinks, trapping heat and forcing components to work harder. This extra stress can lead to slower performance, random shutdowns, and even permanent hardware damage. Regularly blowing out dust from your computer prevents this buildup and helps keep your system running smoothly and quietly.

Clean airflow is one of the most important factors for maintaining ideal operating temperatures. When dust clogs the cooling system, heat lingers longer inside your case, shortening the lifespan of components like the CPU, GPU, and power supply. By using compressed air or an electric air duster, you can easily clear out debris from fans, radiators, and filters. This simple habit often results in noticeably better performance, lower fan noise, and fewer overheating issues — all without spending a dime on upgrades.

Beyond performance, cleaning your PC also contributes to better stability and energy efficiency. When components stay cool, they consume less power and run more consistently, reducing the chance of crashes or throttling during heavy workloads. For gamers, IT pros, and creative professionals alike, this means smoother frame rates, faster rendering, and longer hardware life.

Finally, dusting out your computer is quick, cheap, and surprisingly satisfying. It’s one of the easiest forms of preventive maintenance you can do — no technical skill required. A few blasts of air every couple of months can save you hundreds in future repairs or replacements. So the next time you notice your fans sounding like jet engines, grab that can of air and give your machine the breath of fresh air it deserves.

Trim the Fat: Maximizing Efficiency with Wireshark’s Editcap Utility

Wireshark’s Editcap utility is an unsung hero for network analysts dealing with massive packet captures. When troubleshooting complex networks or long-running sessions, trace files can balloon into gigabytes, making them difficult to open, share, or analyze efficiently. Editcap solves this by allowing users to reduce capture file size without losing the essence of the data. By trimming unnecessary packets or narrowing the capture window to a specific timeframe, engineers can focus their analysis on the most relevant portions of traffic — saving both time and system resources.

Another major advantage of Editcap is its ability to filter and split trace files for targeted analysis. For example, you can easily segment a huge multi-hour capture into smaller, manageable files or isolate traffic related to a single host or protocol. This feature is especially useful when sharing data with colleagues or vendors who only need a specific slice of the network conversation. Smaller, more focused traces mean faster load times and easier collaboration, all while maintaining the integrity of the analysis.

Editcap also helps improve performance and stability during packet analysis. Wireshark, while powerful, can struggle with extremely large captures — causing lag, high memory consumption, or even crashes. By pre-processing the data with Editcap, you ensure Wireshark loads only what’s necessary, resulting in a smoother and faster workflow. It’s the digital equivalent of decluttering your workspace: you retain the essentials while removing the noise that slows you down.

Finally, Editcap brings automation and precision to the network analysis process. With simple command-line syntax, it integrates seamlessly into scripts or automated workflows, making it ideal for continuous monitoring environments. Whether you’re capturing data for compliance, performance testing, or troubleshooting, Editcap helps you keep trace files lean, focused, and ready for rapid insight. In short, it’s not just a file reduction tool — it’s a force multiplier for anyone serious about efficient packet analysis.

Is it time to change your Google password

I suggested to a long time client that they change their google password and was surprised when i saw the date of the last password change..

If you haven’t changed your Google password since the last major data breach, now’s the time to do it. Even if your account wasn’t directly affected, breaches often expose login credentials that hackers later sell or reuse across other services. Since many people reuse passwords (even slightly modified ones), a compromised database from any site could put your Google account at risk. Changing your password helps reset that exposure and ensures that anyone who may have obtained your old credentials can’t get in.

Beyond your emails, your Google account is the key to a lot more—Drive files, Photos, Maps history, and even linked third-party apps. A single unauthorized login could expose personal or professional information, and attackers can move fast once they’re in. Updating your password acts like changing the locks on your digital home after hearing someone’s been picking doors in the neighborhood. It’s a small action that greatly reduces your vulnerability.

When you change your password, it’s also a good moment to strengthen your security overall. Choose a strong, unique password (or use a password manager), and make sure two-factor authentication is turned on. This way, even if your credentials ever leak again, that extra verification step will protect you. Staying proactive with password hygiene isn’t paranoia—it’s digital self-defense in an age where breaches are more common than ever.

  what do you think.  ;)

Cracking the MTU Mystery: How Wireshark Uncovers Hidden Network Bottlenecks

When troubleshooting network performance issues, especially when tools like iperf3 show inconsistent throughput between two devices, one of the most overlooked culprits is an MTU (Maximum Transmission Unit) mismatch or mismatch with an intermediate network device. MTU defines the largest size of a packet that can be transmitted without fragmentation. If two devices are operating with incompatible MTU settings, packets may be fragmented, dropped, or delayed—leading to unpredictable performance results. This is where Wireshark, a powerful packet capture and analysis tool, becomes indispensable.

Wireshark allows you to see exactly what’s happening at the packet level. By capturing and analyzing traffic during an iperf3 test, you can identify telltale signs of MTU problems—such as fragmented packets, “Fragmented IP Protocol” warnings, or ICMP “Fragmentation Needed” messages. These insights go far beyond what iperf3 alone can reveal, turning Wireshark into a digital microscope for your network. Instead of guessing where the problem lies, you can pinpoint the exact source of inefficiency.

Another key advantage of using Wireshark in MTU troubleshooting is its ability to visualize the packet flow and timing in real time. Engineers can track how packets traverse the network path, detect retransmissions, and confirm whether packets are being dropped due to size constraints. With its advanced filtering capabilities, Wireshark lets you isolate just the traffic between your two iperf3 endpoints, simplifying analysis and helping you focus on what matters most.

Ultimately, using Wireshark to investigate MTU issues transforms guesswork into data-driven problem solving. Instead of applying random fixes—like adjusting MTU values on routers or host NICs—you can make precise, evidence-based changes. The combination of iperf3 for performance testing and Wireshark for deep packet inspection provides a complete view of the network’s behavior. Together, they empower you to eliminate performance bottlenecks, ensure optimal throughput, and maintain a smooth, efficient connection between your devices.

See, sometimes “The Network” can be the problem.

Keysight: How to Overcome the Darkside of Moving Apps to the Cloud

First up, the paper kicks off by acknowledging the big promise of public cloud platforms: faster time-to-market, flexibility, scalable business apps, and so on. But it quickly pulls back the curtain and warns that many organizations hit a “dark side” — unexpected performance issues, runaway costs, downtime, and diminished ROI. In fact, the data shows a hefty chunk of companies are already pulling workloads back on-premises because the cloud move didn’t go as expected.

Then, it digs into the root of the issues. A big culprit: organizations leap into the cloud without a clear strategy for which apps should move and why. That can lead to costly cycles of move → undo → re-move. It also lists core problem areas: security concerns, performance degradation, vendor lock-in, multi-cloud complexity, and hidden costs. The paper emphasizes that the cloud isn’t automatically better just because “cloud” sounds good — you still need to plan thoughtfully.

The next part of the paper deals with getting visibility and monitoring in place. If you move apps to the cloud (or mix cloud + on-premises), you must still see what’s going on: traffic, latency, application performance, security anomalies. Without that visibility you’re flying blind and can’t detect problems or validate that your cloud provider is delivering. It talks about building a three-layer visibility architecture (data access, control plane, monitoring layer) plus active monitoring tools and synthetic tests to stress applications and ensure SLAs really hold up.

Finally, the paper offers a pragmatic conclusion: there’s no one-size-fits-all answer. If cloud doesn’t make sense for some workloads, moving them back on-premises or using a hybrid model might be the best move. The goal is to pick the right tool for the right job, not just chase hype. It emphasizes that visibility isn’t optional — you must have a scalable architecture for it — and that a hybrid approach may give you the flexibility to harness cloud benefits when they work, and keep control when they don’t.

Adding a Wireshark icon on your Kali Linux desktop

 Having a Wireshark icon right on your Kali Linux desktop might seem like a small convenience, but it can make a big difference in efficiency. Instead of navigating through menus or typing commands to launch the tool, one click instantly opens Wireshark, getting you straight to packet analysis. When working in fast-paced environments like penetration testing or incident response, that quick access can be the difference between catching a critical packet and missing it.

A desktop icon also serves as a constant reminder of one of the most powerful tools in your cybersecurity toolkit. Wireshark is essential for inspecting traffic, identifying anomalies, and diagnosing network issues. By keeping it visible and easily accessible, you’re more likely to use it frequently — reinforcing good habits and encouraging continuous network monitoring rather than waiting until something breaks.

Finally, a Wireshark desktop shortcut simplifies multitasking and experimentation. Kali users often juggle multiple tools and terminal windows, so launching Wireshark with a single click keeps workflows smooth and organized. Whether you’re capturing live traffic, replaying saved traces, or analyzing suspicious packets, that quick-start icon saves time and helps maintain focus — a subtle yet effective way to boost productivity in your cybersecurity operations.
