After a few frustrating weeks working with the Aruba Technical Assistance Center (TAC). I have our Aruba wireless controllers working with our Central on Premises (COP) cluster.
Aruba’s documentation consisted of a brief and incorrect work document and the instructions in the COP documentation are not clear on what exactly needs done.
So I’ve written up the instructions in a PDF document to try and save others from the same pain. See below.
Well, we all know what else happened in 2020, but I had just a couple other adventures that made 2020 a banner year.
First, in July I fell at work, and this happened:
I had two stays in the hospital and ended up having one surgery on my elbow and three on my knee (I’ll spare you the pictures of my knee, let’s just say it looked like it was stung by a jellyfish and leave it at that).
So, we’ve been living in a rental house for the last nine months (much better than a hotel), while our house was pretty much completely rebuilt. We are hoping to move back in near the end of September of 2021.
We are all doing okay, but I haven’t had much time or opportunities for hobbies 🙂 Here’s hoping your 2020 was safer, healthier, and more prosperous.
I’ve been helping my son get his 3D printer up and running.
It’s a Creality Ender 3, which is a low cost entry level printer. It has some design flaws, but most of them can be mitigated by printing additional parts.
I’m using the open source slicer Cura from Ultimaker with the addition of the Creawsome Mod.
So far I’ve added the following parts (from Thingiverse)
Thanks to the help of my friends, new radio, and plenty of BIC (Butt in Chair) time, I made the most contacts in this year’s Field Day 2019! A good time was had by all! Looking forward to next year!
I’ve been in the process of installing a new Hustler 6-BTV HF antenna I purchased from DX Engineering. It is replacing a used Cushcraft R7 that I’ve had for 7 years.
The antenna itself is up and guyed. Now I just need to install ground radials and tune it up!
I’ve been troubleshooting a Voice over IP (VoIP) issue at work, so I thought it would be a good time to try my hand at setting up a couple of Asterisk servers and linking them with SIP trunks.
Asterisk 16 now uses the PJSIP module by default and while I found plenty of examples of how to set up a trunk to a VoIP provider using PJSIP, there was nothing on how to configure the other end.
Finally after two days I figured it out, and hopefully to save others from the pain, I ‘ve documented the configuration below.
