In my last post, I wrote about how I installed a new kernel onto my old C.H.I.P. As it turned out, not long after writing that post my C.H.I.P. died. It wouldn’t respond to anything, and the heartbeat blinking LED stopped. I didn’t bother to connect a serial port to […]
I have this C.H.I.P. from NextThingsCo lying around. It was a $9 computer, and more or less equivalent to a Raspberry Pi Zero, although it has built in flash storage and WiFi. For the price, it’s not bad. Problem is, the company went bankrupt quite a while ago now and […]
I run an unprivileged Ubuntu 20.04 container on Proxmox, and I recently needed to install snapd for some required software. Unfortunately, snapd seems to require some permissions not normally allocated and fails with the following error: error: system does not fully support snapd: cannot mount squashfs image using “squashfs”: mount: […]
Last week, I was asked to give a guest lecture to students of MECH 383 at McGill University on deep learning and machine learning. I created a slide deck for this lecture, as I could not find anything online that I liked or felt comfortable using given the requirements, which […]
Continuing the Zabbix series, there are some machines I want to monitor that are behind firewalls or NAT devices I do not control. Thus, I cannot use any passive Zabbix services, and my agent must be active only. This means that the agent connects every few minutes to the Zabbix […]
In this post, I’ll go over how to set up Zabbix for a SMTP mail server. I assume you have already followed my previous post and have a running Zabbix server. Preparation To install the Zabbix agent on a Ubuntu based system, you need to follow step 2.a. from their […]
Recently, I’ve had a number of issues with multiple servers, and decided to set up monitoring to help keep track of problems. I chose Zabbix based on the recommendation of Tom Lawrence, as being in the MSP business his recommendations are generally good to follow unless you have a very […]
I’ve been experimenting with Zabbix recently. Unfortunately, as with most things, just following the documentation to install it is a chore. I ended up at the step where I need to import data into my new MySQL database: Of course, it didn’t exist! Luckily, thanks to a post by a […]
The Problem As much as events like World IPv6 day have tried to promote IPv6 and push its adoption, there remain many sites and Internet Service Providers that either don’t support IPv6 or don’t do it well. Luckily, my ISP (Ebox) does it fairly well, but it has not been […]
Jan 2023 Update: Looks like this is no longer an option. It’s still “free”, but requires renewal every month. Before, that renewal was free, but there is now a setup fee of sorts? Not sure if this is a recurring cost, or if they’re somehow charging for the initial setup […]
