Edgerouter X Radius Server Authentication
What the heck is RADIUS? RADIUS (Remote Authentication Dial-In User Service) is a protocol used to manage and secure network access. In simple terms, it's a system that helps ensure that only authorized users can connect to a network. Think of is as a server that network devices
To Bot or Not to Bot?
The debate over AI is far from settled. Competing views on appropriate use of generative AI chatbots range from allowing full, unfettered implementation to blocking their use altogether. Some advocate age restrictions. I wrote on the topic of AI in this post and have not been persuaded into a changed
Itching for Answers
Ah, spring! The season of renewal, blooming flowers, and... allergy-itchy skin and eyes? Yes, you read that right. I find myself battling not with the complexities of network configurations but with the irritating discomfort of dry skin and a bit of python code. At least pythons don’t bite, am
Analog to VoIP
Well, it’s March again, and that means at least one thing: it’s time to revisit my phone situation. For anyone who doesn’t know, life abroad comes with a slew of challenges, not least among them being telephony. It was two years ago when I came across an
Chase Away Winter with Ghost
February is finally over. I am all about the love and romance and kitsch of Valentine's Day, but even still, I am always thrilled for February to wind down as the winds of March guster and bluster through the streets, whipping up whatever duster they can muster—you

Docker Networks
It’s a bit surprising I haven’t mentioned Docker more often on this site yet. Docker is such a great platform for containerization. To be fair, I have mentioned and even demonstrated LXC containers a few times, but Docker as a container engine has been notably absent form this
Fabric for Your Inner Foodie
Yesterday, my wife, daughter, and I made the trek to 종로 (Jongno, Seoul’s central district) to buy some fabric to make 한복 (hanbok, traditional Korean attire); my wife is the crafty one, so the sewing will be her job. The plan was to buy some fabric and then head
Dynamic VLAN assignment with RADIUS
Just some of the benefits of using WPA3-Enterprise authentication. 1. You can use the same SSID (Wi-Fi name) for different networks. 2. Users are authenticated and authorization is grated with per-group permissions. 3. Users are dropped into the VLANs their user group is authorized for. 4. Admins can change access
Finish Lines
Finish lines in IT seldom have trophies or uproarious applause. Satisfaction in a job done well is a reward in itself. However, there is little praise for solving an unnoticed problem no matter the improvement to quality of life it brings. An obvious solution would be to announce, with much
Destination UniFi
The Cult of Cool called UniFi has long since laid out its Kool-aid and cookies for guys like me. I’ve resisted them (the cookies and UniFi) as long as I could. But while you were tucked up in you bed all snug, warm, and waiting for Jolly-ol’ St. Nic

Deploy VMs like never before
As a student of the dark arts of networking, my journey in the wonderful world of technology has taken an unexpected turn. While I typically delve into the intricacies of the TCP/IP stack, VLANs, or spanning tree protocol, recent events in my homelab prompted me to explore a different
Multiple VLAN DHCP in 10 Minutes
Defining Some Terms VLAN: Virtual Local Area Network. I've discussed VLANs extensively before. They are a way to keep traffic separated on different networks. In order for a host on one VLAN to communicate with hosts in another VLAN (and thus another network), there needs to be a
Happy birthday to me
Well, I don’t think I can really do the day justice in a fitting description or recounting of it, but it was recently my birthday. the day was full and rich. Upon arriving home from dropping my daughter off at kindergarten where she was especially sweet to me in
