If you checked in with me earlier, you saw the following placeholder text, but I thought I would leave it here, so you can get a flavour for how excited I was to bust out something--anything--on this topic. "I’m out and about with my beautiful bride at the
I need to catch you up on my training journey. Last I mentioned anything about next steps and what to do after passing CCNA, I announced that the next dedicated study would be the Cisco ENAUTO. Well, that was three weeks ago, and I have finished the last of the
Programming has become an essential skill to automate and manage network infrastructure effectively. Python, with its simplicity and versatility, is the go-to programming language of choice in the networking domain. In a previous blog post, I attempted to explain a Python script that I had learned how to build earlier
Netmiko is a multi-vendor library in Python that simplifies the process of interacting with network devices, such as routers and switches, through SSH and Telnet connections. It provides a consistent and programmatic interface for automating network device configuration and management tasks. Netmiko allows you to use Python on devices that
Dad jokes aside, this post is just a short video about restconf. Restconf, for the unfamiliar, is a protocol for programatically interacting with a network appliance. It allows you to leverage the power of a programming language called Python to configure and monitor fleets of routers and switches with a
Why VLANs? Computer networks are vital for our connected world, enabling communication and data transfer. One important concept within these networks is Virtual Local Area Networks (VLANs). In simple terms, VLANs help organize devices, improve security, boost performance, and make network management easier. Let's dive into VLANs and
Cisco VTP (VLAN Trunking Protocol) is a proprietary protocol used in Cisco networking devices to manage and propagate VLAN (Virtual Local Area Network) configurations across a switched network. VTP allows network administrators to create, delete, and modify VLANs on a central switch, known as the VTP server, and have those
After receiving my CCNA and following up with the JNCIA certification, the next steps in my professional development as a network engineer have been anything but clear. In that I immensely enjoyed my Juniper studies, I initially thought the most natural next focus should be the JNCIS-ENT. But then there
Before I really get into this post, I need to say thank you to my wife’s cousin’s fiancé. Without him, this post would not have happened. He and his wife-to-be came to visit our home for lunch one Sunday afternoon. He said his English was not that great,
There are many tools network administrators and security professionals rely on to provide insights into network traffic and vulnerabilities. We’ll take a look at two of my favorite tools today, Wireshark and Nmap. That and I thought this topic dovetailed nicely with the post about enabling SSH on a
I really wanted to be lazy and just post the video I shot for this post instead of just typing it out, but the upload failed twice already—too much work! Anyway, what I wanted to talk about was the Juniper JNCIA-Junos Exam I took yesterday—and passed (hooray)! Juniper
Getting ready for the upcoming exam, I realize this will be much more than just a prayer and crossed fingers in the hopes of passing. The Juniper JNCIA-JUNOS exam is rumored to be much easier than the Cisco CCNA exam, but I won't let that notion lull me
rain fell in torrents umbrellas fought tsunamis I went back to bed
I stepped out into the rainy-wet streets to start my day with a quick run this morning, it dawned on me as I struggled to get moving that, though I've maybe expressed this thought in a number of variant ways in the past and to a handful of
I’m amazed at how even just a little bit of travel hits the reset button on the creative flow. It is as though the hum-drum of everyday life droning on drowns out the whispers of inspiration. But when you venture out into the unknown, whether it's to
Your mom doesn't work here—clean up after yourself! Descending into the smoggy haze that calls itself home after a reprieve with a clean-sky week abroad, I was reminded of just how much filth we subject each other to in Seoul. The first place I headed after getting
