Migrating IP Addressing Schemes

Matt/ May 24, 2017

Back a few months ago, I wrote a bit about why it is important to have a good design for IP addressing schemes (part 1 and part 2). As a brief refresher, the situation I found myself in was an environment where practically everything was assigned a 10.x.x.x/16 subnet – even if we only needed a handful of hosts. When

How to: Synology Backups with CrashPlan

Matt/ May 16, 2017

As part of my home lab, I have an older Synology DS411 that I picked up in early 2012. I’ve been using the device since then with 4x 3TB drives as an iSCSI backend to my ESX host.

Alright – Now What?

Matt/ May 11, 2017

So it’s now been over two months since I finished college and obtained my magical piece of paper. It has been interesting to finally have some free time to do things that I want to do, and not having to constantly balance my time between school and work.

A while back I wrote some basic information on how to get started implementing multi-homed internet using BGP.

Tracking Latency and Packet Loss with SmokePing

Matt/ April 25, 2017

“The network is slow” – Sound like something you’ve heard before? What does ‘slow’ mean anyway? And is it different from yesterday? Sometimes tracking down network ‘slowness’ can be pretty difficult, especially when you don’t have a good baseline of what is normal. This kind of goes back to one of the tips I shared earlier in ‘A Little Bit of

Juniper SRX VPN Issues

Matt/ April 18, 2017

Last year we began migrating from our old Juniper SSG firewalls to the new SRX line. After a few months, I’ve honestly really started to enjoy working with them – so much that we’ve decided to start standardizing our firewall platforms by ditching everything else. So far I’ve had the opportunity to install ten SRX 1500s, six SRX 345s, and one

Guilty Until Proven Innocent: How to Prove It’s Not the Network

Matt/ April 11, 2017

If there is one thing you learn very quickly in networking, it’s that everything is always the fault of the network. Two systems cannot communicate? Yeah, that’s always a network problem. Something is inaccessible? Probably the network. What about that broken toaster? Definitely a network issue. Starting off as a less experienced network engineer, this can easily get overwhelming. A

Matt/ March 28, 2017

As of the beginning of this month, I have officially completed my four years of trying to balance working full time and going back to school. I finished up my last college classes and now I can sit back and appreciate having some free time to myself again. I’ve never been really into the concept of school, but ultimately I went back because

Why Have a Home Lab?

Matt/ March 21, 2017

If you really want to become great at something, you practice it a ton, right? Well networking and IT work exactly the same. You’re not going to become an expect by just reading a ton of tech books and blogs. While those certainly help, there is nothing better than simply getting your hands dirty.
