Do You Do What You’ve Always Done?

When I was an intern at IBM twenty something years ago, my job was deploying new laptops to people. The job was easy enough. Transfer their few hundred megabytes of data to the new machine and ensure their email was all setup correctly. There was a checklist that needed to be followed in order to ensure that it was done correctly.

When I arrived for my internship, one of my friends was there finishing his. He was supposed to train me in how to do the job before he went back to school. He helped me through the first day of deploying laptops following the procedure. The next day he handed me a different sheet with some of the same information but in a different order. He said, “I realized we had too many reboots in the process and this way cuts about twenty minutes off the deployment time.” I’m all about saving time so I jumped at the chance.

Everything went smashingly for the next month or so. My friend was back at school and I used his modified procedure to be as productive as possible. One day, my mentor wanted to shadow my deployment day to see Continue reading

Imposters Among Us

Have you been playing Among Us? If you haven’t, your kids definitely have. I found out about it a few weeks ago because my children suddenly became Batman-level detectives and knew how to ask the kinds of interview questions that would make the FBI proud. In short, the game is all about finding the imposters in your midst based on their behavior and voting them out of the group to win. Sometimes you get it right. Other times you get it wrong and vote out someone who was doing legitimate tasks. It’s all a matter of perception.

Now, let’s look at another situation where we see this kind of behavior in a different light. You probably guessed where this is going already. We’re going to talk about Imposter Syndrome in our non-gaming lives and how it affects us. We may even make reference to pop culture along the way.

Where You Need To Be

I was thinking about this because something I said a few years ago at Security Field Day 1 popped back up in my feed. I was giving a speech at the beginning of the first day to the delegates and I wanted them to know that Continue reading

When Will You Need Wi-Fi 6E at Home?

The pandemic has really done a number on most of our office environments. For some, we went from being in a corporate enterprise with desks and coffee makers to being at home with a slightly different desk and perhaps a slightly better coffee maker. However, one thing that didn’t improve was our home network.

For the most part, the home network has been operating on a scale radically different from those of the average corporate environment. Taking away the discrepancies in Internet speed for a moment you would have a hard time arguing that most home wireless gear is as good or better than the equivalent enterprise solution. Most of us end up buying our equipment from the local big box store and are likely shopping as much on price as we are on features. As long as it supports our phones, gaming consoles, and the streaming box we picked up we’re happy. We don’t need QoS or rogue detection.

However, we now live in a world where the enterprise is our home. We live at work as much as we work where we live. Extended hours means we typically work past 5:00 pm or start earlier than 8:00 or Continue reading

Thoughts From Networking Field Day 23

I know I’m a little late getting this post out but Networking Field Day 23 was a jam-packed event with lots of things to digest. I wanted to share some quick thoughts about it here that should create some discussion amongst the community, hopefully.

  • If you don’t believe that wireless is the new access edge, go look at Juniper. Their campus networking division is basically EX switching and Mist. That’s it. Remember how HPE called Aruba a “reverse acquisition” years ago? And how Aruba essentially took over the networking portion of HPE? Don’t be surprised to see Juniper getting more misty sooner rather than later. And that’s a good thing for everything that isn’t a carrier or service provider router.
  • Network monitoring became telemetry and is now transforming into digital experience. What is the difference to me? Monitoring devices tells you point-in-time information. Telemetry gives you the story of those point-in-time measurements over the course of days or weeks and can help you find issues. Experience is all about how that looks to your users. Problems don’t always affect them the same way it might appear on a dashboard. Likewise, things you don’t always see in your alerts can affect Continue reading

A Decade of Blogging

Today is a milestone for me. Ten years ago I picked up a virtual notepad for the first time and committed my first blog post to the ether. It’s been a wild ride ever since. It also marks the milestone of being the job that I’ve held the longest so far in my career.

Blogging has been a huge boon for me. I’ve become a better writer in the last decade. I’ve learned how to ask the right questions and get good material for a story instead of just putting out what someone wants me to say. I’ve learned that being a pseudo-journalist is a thing you can do and have fun with.

I’ve written a ton over the years. 751 posts, as a matter of fact (counting this one). I’ve always tried to hold myself to a standard of getting something out once a week. Aside from the few times when I’ve tried to push that to twice a week I’ve held up pretty well. Yeah, I’ve slipped and the day job has gotten in the way more than once. However, keeping myself to a strict schedule has ensured that my attention stays focused on this blog and that Continue reading

Solve the Simple Problems

One thing I’ve found out over the past decade of writing is that some problems are easy enough to solve that we sometimes forget about them. Maybe it’s something you encounter once in a great while. Perhaps it’s something that needed a little extra thought or a novel reconfiguration of an existing solution. Something so minor that you didn’t even think to write it down. Until you run into the problem again.

The truth behind most of these simple problems is that the solutions aren’t always apparent. Sure, you might be a genius when it comes to fixing the network or the storage array. Maybe you figured out how to install some new software to do a thing in a way that wasn’t intended. But did you write any of it down for later use? Did you make sure to record what you’ve done so someone else can use it for reference?

Part of the reason why I started blogging was to have those written solutions to problems I couldn’t find a quick answer to. What it became was way more than I had originally intended. But the posts that I write that still get the most attention aren’t my Continue reading

A Place for Things and Things in Their Place

This morning I was going to go for a run and I needed to find a rain jacket to keep from getting completely soaked. I knew I had one in my hiking backpack but couldn’t locate it. I searched for at least ten minutes in every spot I could think of and couldn’t find it. That is, until I looked under the brain of the pack and found it right next to the pack’s rain cover. Then I remembered that my past self had put the jacket there for safe keeping because I knew that if I ever needed to use the pack rain cover I would likely need to have my rain jacket as well. Present me wasn’t as happy to find out past me was so accommodating.

I realized after this little situation that I’ve grown accustomed to keeping my bags organized in a certain way both for ease of use and ease of inspection. Whether it’s a hiking backpack or an IT sling bag full of gadgets I’ve always tried to set things up in simple, sane manner to figure out how to find the tools I need quickly and also discover if any of them are Continue reading

Fast Friday- Labor Day Eve Edition

It’s a long weekend in the US thanks to Labor Day. Which is basically signaling the end of the summer months. Or maybe the end of March depending on how you look at it. The rest of the year is packed full of more virtual Zoom calls, conferences, Tech Field Day events, and all the fun you can have looking at virtual leaves turning colors.

It’s been an interesting news week for some things. And if you take out all the speculation about who is going to end up watching TikTok you are left with not much else. So I’ve been wondering out loud about a few things that I thought I would share.

  • You need a backup video conferencing platform. If Zoom isn’t crashing on you then someone is deleting WebEx VMs. Or maybe your callers can’t get the hang of the interface. Treat it like a failing demo during a presentation: if it doesn’t work in five minutes, go to plan B. Don’t leave your people waiting for something that may not happen.
  • If you work in the backbone service provider market, you need to do two things next week. First, you need to make sure all your Continue reading

Iron Chef: Certification Edition

My friend Joshua Williams (@802DotMe) texted me today with a great quote that I wanted to share with you that made me think about certifications:

You’ve probably already thought through this extensively, and maybe even written about it, but after sitting through another 8 hour practical exam yesterday I’m more convinced than ever that expert level exams from technical companies are more analogous to a gimmicky Food Network TV show than real world application of technical acumen. They don’t care so much about my skill level as they do about what kind of meal I can prepare in 30 minutes using Tialapia, grapes, and Dr. Pepper syrup with my salt shaker taken away halfway through.

I laughed because it’s true. And then I thought about it more and realized he’s way more than right. We know for a fact that companies love to increase the level of challenge in their exams from novice to expert. It’s a way to weed out the people that aren’t committed to learning about something. However, as the questions and tasks get harder it becomes much more difficult to get a good sense of how candidates are going to perform.

Opening Up Remote Access with Opengear

Opengear OM2200

The Opengear OM2200

If you had told me last year at this time that remote management of devices would be a huge thing in 2020 I might have agreed but laughed quietly. We were traveling down the path of simultaneously removing hardware from our organizations and deploying IoT devices that could be managed easily from the cloud. We didn’t need to access stuff like we did in the past. Even if we did, it was easy to just SSH or console into the system from a jump box inside the corporate firewall. After all, who wants to work on something when you’re not in the office?

Um, yeah. Surprise, surprise.

Turns out 2020 is the Year of Having Our Hair Lit On Fire. Which is a catchy song someone should record. But it’s also the year where we have learned how to stand up 100% Work From Home VPN setups within a week, deploy architecture to the cloud and refactor on the fly to help employees stay productive, and institute massive change freezes in the corporate data center because no one can drive in to do a reboot if someone forgets to do commit confirmed or reload in 5.

Is Bandwidth A Precious Resource?

During a recent episode of the Packet Pushers Podcast, Greg and Drew talked about the fact that bandwidth just keeps increasing and we live in a world where the solution to most problems is to just increase the pipeline to the data center or to the Internet. I came into networking after the heady days of ISDN lines everywhere and trying to do traffic shaping on slow frame relay links. But I also believe that we’re going to quickly find ourselves in a pickle when it comes to bandwidth.

Too Depressing

My grandparents were alive during the Great Depression. They remember what it was like to have to struggle to find food or make ends meet. That one singular experience transformed the way they lived their lives. If you have a relative or know of someone that lived through that time, you probably have noticed they have some interesting habits. They may keep lots of cash on hand stored in various places around the house. They may do things like peel labels from jelly jars and use them as cups. They may even go to great lengths to preserve as much as they can for reuse later “just in Continue reading

Appreciation Society

Given how crazy everything is right now, it’s important to try and stay sane. And that’s harder than it sounds to be honest. Our mental health is being degraded by the day. Work stress, personal stress, and family stress are all contributing to a huge amount of problems for all of us. I can freely admit that I’m there myself. My mental state has been challenged as of late with a lot of things and I’m hoping that I’m going to pull myself out of this funk soon with the help of my wife @MrsNetwrkngnerd and some other things to make me happier.

One of the things that I wanted to share with you all today was one of the things I’ve been trying to be mindful about over the course of the last few months. It’s about appreciation. We show appreciation all the time for people. It’s nothing new, really. But I want you to think about the last time you said “thank you” to someone. Was it a simple exchange for a service? Was it just a reflex to some action? Kind of like saying “you’re welcome” afterwards? I’d be willing to bet that most of the people Continue reading

Fast Friday – Mobility Field Day 5 Edition

I’ve been in the middle of Mobility Field Day 5 this week with a great group of friends and presenters. There’s a lot to unpack. I wanted to share some quick thoughts around wireless technologies and where we’re headed with it.

  • Wireless isn’t magic. We know that because it’s damned hard to build a deployment plan and figure out where to put APs. We’ve built tools that help us immensely. We’ve worked on a variety of great things that enable us to make it happen easier than it’s been before. But remember that the work still has to happen and we still have to understand it. As soon as someone says, “You don’t need to do the work, our tool just makes it happen” my defenses go up. How does the tool understand nuance? Who is double-checking it? What happens when you can’t feed it all the info it needs? Don’t assume that taking a human out of the loop is always good thing. Accrued knowledge is more important than you realize.
  • Analytics give you a good picture of what you want, but they don’t turn wrenches. All the data in the world won’t replace a keyboard. You need to Continue reading

Video Meetings and Learning Styles

Have you noticed that every meeting needs to be on video now? Of course, that’s a rhetorical question. It’s one of the first and most constant things that is brought up in the pandemic-influenced tech community of today. Meetings that used to be telephone-only or even wordy emails are now video chats that take half an hour or more. People complain that they are spending time and money to spruce up their office to look presentable at 720p to people that likely aren’t paying attention anyway. It’s a common complaint. But have you ever thought about why?

Listening and Looking to Learn

There are three major styles of learning that get brought up in academic courses.

  • Physical, or kinesthetic, learners learn best from touching things. They want to manipulate and feel things as they learn. They like to gesture when they talk. They also get bored quickly when things are taking too long or they have to sit still too much.
  • Visual learners learn best from seeing things. They like to look around and tend to think in pictures. They would rather see something instead of hearing someone speak.
  • Auditory learners like to hear things being spoken. They want to Continue reading

The Silver (Peak) Lining For HPE and Cloud

You no doubt saw the news this week that HPE announced that they’re buying Silver Peak for just shy of $1 billion dollars. It’s a good exit for Silver Peak and should provide some great benefits for both companies. There was a bit of interesting discussion around where this fits in the bigger picture for HPE, Aruba, and the cloud. I figured I’d throw my hat in the ring and take a turn discussing it.

Counting Your Chickens

First and foremost, let’s discuss where this acquisition is headed. HPE announced it and they’re the ones holding the purse strings. But the acquisition post was courtesy of Keerti Melkote, who runs the Aruba, a Hewlett Packard Enterprise Company (Aruba) side of the house. Why is that? It’s because HPE “reverse acquired” Aruba and sent all their networking expertise and hardware down to the Arubans to get things done.

I would venture to say that Aruba’s acquisition was the best decision HPE could have made. It gave them immediate expertise in an area they sorely needed help. It gave Aruba a platform to build on and innovate from. And it ultimately allowed HPE to shore up their campus networking story while trying Continue reading

Fast Friday Random Thoughts

It’s Friday and we’re technically halfway into the year now. Which means things should be going smoother soon, right? Here’s hoping, at least.

  • I posted a new episode of Tomversations yesterday. This one is about end-to-end encryption. Here’s hoping the Department of Justice doesn’t find a way to screw this up. And here’s hoping the Senate stops helping.
  • I saw a post that posits VMware may be looking to buy BitGlass. I know VMware’s NSX team pretty well. I also talked to the BitGlass team at RSA this year. I think this is something that VMware needs to pick up to be honest. They need to round out their SASE portfolio with a CASB. BitGlass is the best one out there to make that happen. I think we’re going to see a move here before we know it.
  • There are a lot of other acquisitions going on in the market. VMware bought Datrium. Uber bought Postmates. It’s typical to see these kinds of acquisitions during downturns because it becomes way cheaper to snap up your competition. I expect Q3 is going to be full of consolidation in the networking space. Cisco won’t start doing anything until August at the earliest, Continue reading

Podcasts I’m Playing in 2020

Since I seem to have a lot more time on my hands without travel thanks to current…things, I’ve been consuming podcasts more and more during my morning workouts. I’ve got a decent list going now and I wanted to share it with you. Here are my favorite podcasts (not including the one that I do for Gestalt IT, the On-Premise IT Roundtable:

  • Packet Pushers – The oldest and best is still my go-to for listening. I started back at Episode 3 or 4. i can remember the intro music. And I’ve been a guest and a participant more times than I can count. Greg, Ethan, and Drew do an amazing job of collecting all the info about the networking world and pushing it to my ears daily. When you through in their news feed (Network Break), cloud (Day Two Cloud), DevOps (Full Stack Journey), IPv6 (IPv6 Buzz), and one-off stuff (Briefings in Brief) there’s a lot to consume aside from their Heavy Networking “main” feed. You can sub to any or all of these if you want. And stay tuned because you might hear me from time to time.
  • Network Collective – Jordan is one of my old and Continue reading

Data Is The New Solar Energy

You’ve probably been hearing a lot about analytics and artificial intelligence in the past couple of years. Every software platform under the sun is looking to increase their visibility into the way that networks and systems behave. They can then take that data and plug it into a model and make recommendations about the way things need to be configured or designed.

Using analytics to aid troubleshooting is nothing new. We used to be able to tell when hard disks were about to go bad because of SMART reporting. Today we can use predictive analysis to determine when the disk has passed the point of no return and should be replaced well ahead of the actual failure. We can even plug that data into an AI algorithm to determine which drives on which devices need to be examined first based on a chart of performance data.

The power of this kind of data-driven network and systems operation does help our beleaguered IT departments feel as though they have a handle on things. And the power that data can offer to us has it being tracked like a precious natural resource. More than a few times I’ve heard data referred to Continue reading

The Conundrum of Virtual Conferences

Okay, the world is indeed crazy. We can’t hide from it or hope that it just blows over sooner or later. We’re dealing with it now and that means it’s impacting our work, our family lives, and even our sanity from time to time. One of the stalwart things that has been impacted by this is the summer conference schedule. We’ve had Aruba Atmosphere, Cisco Live, VMworld, and even Microsoft Ignite transition from being held in-person to a virtual format complete with shortened schedules and pre-recorded sessions. I’ve attended a couple of these so far for work and as an analyst, and I think I’ve figured it out.

If you come to a conference for content and sessions, you’ll love virtual events. If you come for any other reason, virtual isn’t going to work for you.

Let’s break this down because there’s a lot to unpack.

Information Ingestion

Conferences are first and foremost about disseminating information. Want to learn what new solutions and technologies have been launched? It’s probably going to be announced either right before or during the conference. Want to learn the ins-and-outs of this specific protocol? There’s probably a session on it or a chance to ask Continue reading

Security and Salt

One of the things I picked up during the quarantine is a new-found interest in cooking. I’ve been spending more time researching recipes and trying to understand how my previous efforts to be a four-star chef have fallen flat. Thankfully, practice does indeed make perfect. I’m slowly getting better , which is to say that my family will actually eat my cooking now instead of just deciding that pizza for the fourth night in a row is a good choice.

One of the things I learned as I went on was about salt. Sodium Chloride is a magical substance. Someone once told me that if you taste a dish and you know it needs something but you’re not quite sure what that something is, the answer is probably salt. It does a lot to tie flavors together. But it’s also a fickle substance. It has the power to make or break a dish in very small amounts. It can be the difference between perfection and disaster. As it turns out, it’s a lot like security too.

Too Much is Exactly Enough

Security and salt are alike in the first way because you need the right amount to make things work. Continue reading
