When it comes to money, I don’t like to spend it. Furthermore, one of the key tenets to writing is ‘write what you know’ or so says a few people anyways. So here we are. There is a lot of training out there so in the following I hope to provide stuff that’s not onlyContinue reading ““FREE” IT/Cyber Training for Air Force People”

Basic NBA Data Parsing with Python
About eight weeks ago I saw John Capobianco and Tim Bert were holding an online meeting about trying to pull down some NCAA football data using an API. I, myself, finally finished up the last certification exam I’ve had on my plate shortly thereafter. Since then, I’ve taken to doing a little bit of DataCampContinue reading “Basic NBA Data Parsing with Python”
Making Meaningful Connections Online
You can’t spread yourself too thin on a whole bunch of different social apps if you want to have meaningful online relationships.
TSHOOT – Linux Networking Style
When I got restarted in networking circa 2018-19 everyone on my timeline would always profess how much they loved Cisco’s TSHOOT exam. People had tickets to do and felt like they were showing off what they knew, their experience, rather than answering trivia questions. “I always recert my CCNP with the TSHOOT exam…” or soContinue reading “TSHOOT – Linux Networking Style”
zeek-cut vs jq
Last week I wrote a quick little tutorial so that one could get started using tshark. In this post I want to look at different ways of viewing the same data using a tool called zeek. Zeek is often referred to as a packet examination ‘framework’ as it allows you to see what is happening,Continue reading “zeek-cut vs jq”
tshark the best?!
I wrote a quick intro to tcpdump some months ago as I was learning about the tool and I thought it was just the best. You only love what you know right?! Well last week I embarked on a quest to find some flags on Cisco’s CTF 2021 using tshark. I mean, I originally triedContinue reading “tshark the best?!”
Gitlab + Hugo = Website Magic Happy Time
I should let you know right off the top, this is not a ‘how-to’ from an expert. Instead, this is a how I was able to do something cool for the first time, article. The reason for this post is that I had to use multiple different how-to sites and was still left to troubleshootContinue reading “Gitlab + Hugo = Website Magic Happy Time”
Network Troubleshooting Tip – Model Driven
No matter what the specific role, as an IT professional, you are going to be tasked to solve problems. Whether you are in a direct support role, part of an escalation team, or on the architecture/engineering team, you are potentially seen as someone who “fixes all the things”. Sometimes though, I think it can beContinue reading “Network Troubleshooting Tip – Model Driven”
Starting the GIAC Certification Process
So I’ve made it through just about all of the SANS SEC503 material. That’s no small accomplishment in it of itself and I already feel like I’ve leveled up a bit. I now know some of the secrets about the TCP handshake, checksums and window size 🙂 If you’ve followed me through my first threeContinue reading “Starting the GIAC Certification Process”
Simple Cisco Text File Changes
As we are busy diving into the world of programming and automation, I’d like to remind everyone of a way to make simple config changes to a Cisco switch or router using a text file. This might not be a breakthrough, but it helps when making changes to switches or routers when those changes can possibly disconnect you from the device. Imagine working on a re-IP of a switch or even a point to point link. You have your notepad ready to go. There is a new IP and default route and all you have to do is copy/paste. You paste in the IP and lose connection. Your default route change never actually pasted because you lost connection right after the IP change. You can no longer connect to the device; panic ensues. What might be a better way to make this change and avoid the “Uh oh!” moment?
