The importance of designing things the right way the first time - and the problems that pop up if you don't.
The things they don't teach you in school, but are necessary for the job - and the lessons I've learned.
You can never stop learning - A bit on certification studies and random new technologies.
A little about the magic that happens in the background - and sometimes saves the day.
Over the past few years of my Juniper SRX adventures, I’ve run into a few cases where the Routing Engine (RE) CPU is pegged at 100%. From what I’ve seen so far, this is typically one of three causes: high traffic (spike in IPS inspection), logging using event mode, or a stuck web management session. In a few occasional cases,
It’s August of 2017 – which means it’s been a long ten years since I originally obtained by CCNA certification in 2007. I figured it might be a good time to take a minute and look at what that has meant for me, and how the last ten years of my career have gone. When I got my CCNA certification,
I ran into an interesting issue recently, which was caused by use of the switchport protected command…. So I use a pair of Cisco 2960-8TC-L switches at home, for both my home network and lab. A few months back I ran a bunch of ethernet cabling within my house, which all terminated in a patch panel in the basement. I was able
In last weeks post, we took a look at how to set up a chassis cluster on a Juniper SRX Firewall. So now that we have a basic cluster setup – Let’s explore some of the additional options and configuration items. Redundant Ethernet Interfaces So first thing is first – Once you have a cluster configured, you’ll probably want to
So you just unboxed a brand new pair of Juniper SRX firewalls – now what? Well, the first thing you’re likely going to want to do is get the two devices hooked up and clustered together. That should be pretty simple, right? Yeah, mostly – though there are a few variations between device models, and there are a few fine-print

Part 1 – Initial Thoughts Part 2 – Leaning Django Part 3 – Creating the Dashboard Alright – We’re finally at the last step to this project. We already have Django running with a somewhat decent-looking web dashboard. Now the only
This is a multi-part series – If you just hit this page, please check out the prior posts first! Part 1 – Initial Thoughts Part 2 – Leaning Django In the last post, we got Django working well enough to start serving up web requests. That’s a great start – So now it’s on to actually building the project. We’re
I’ve really been meaning to write this out for a while – but since I’ve been doing a lot of interviewing recently, I figured it’s about time. I’ll be completely honest here, the first few iterations of my resume absolutely sucked. I had a family member help me put one together, and I slowly modified it from there – but
This is a multi-part series – If you just hit this page, please check out the prior posts first! Part 1 – Initial Thoughts Once I figured out the overall idea behind what I wanted to do – the next big part was figuring out where to start. As I mentioned in part 1, I had never used Django before
So maybe you’re like me – you’ve done a bit of everything in the past, but now you’ve specialized on something (like networking). Know what the best part of that is? Using all that knowledge and experience to make things happen. In this case, I’m talking about some of my prior experiences in scripting in automation, paired with some pretty
