Raspberry Pi: SD Card to SSD Drive, part 2

Posted on 11 August 2019 by matthannan

Oh, brother, has this been a mess. I’ve certainly relearned a great deal about Linux partitions and boot sectors and a bunch of other stuff that I used to know cold, but this process has beaten me.

This morning, after about a week of doing battle with this process, and several others, I’ve thrown in the towel and I am rebuilding from scratch.… Read the rest

Source: How to use Windows 10’s built-in OpenSSH to automatically SSH into a remote Linux machine

Amazing how quickly things have changed! This is from January 2019, and it is already dated. Windows 10 now has ssh-copy-id. I am looking for a tutorial on just how to use that now, but the method used here does work.… Read the rest

From the Real World to the Web

Posted on 9 April 2019 by matthannan

Part of my quest for world domination, er, getting my Raspberry Pi to tell me about things in my basement without my having to actually go down there is just about complete.

I bought a temperature and humidity sensor from Adafruit and finally got around to wiring it up and getting the Python code written to read it.… Read the rest

rsyslog & LogAnalyzer, follow-up

Posted on 17 March 2019 by matthannan

Well, it has been a solid day watching these nagging log entries scroll by over and over again.

I just cleared up a cacti issue on Pi1 by determining that I was not actually using cacti for anything and removing it, along with the CRON job that was generating the log entry.… Read the rest

rsyslog and LogAnalyzer

Posted on 16 March 2019 by matthannan

Continuing on in the Raspberry Pi as network server journey, I now have an rsyslog server (Pi1) collecting logs from the various networky things. I am using this Log Analyzer as the frontend. It was a royal PiTA to get working, but now that it is up, it was worth it.… Read the rest

Raspberry Pi POE HAT

Posted on 12 December 2018 by matthannan

I am gearing up to return to this OpenCV project. Changing jobs and such do make hobbies a challenge.
Looking at how to power the Pi once it is installed on the oil tank is causing me some headaches.
I’d love to keep this thing running on WiFi and not have to run an Ethernet cable, but then I am left with having to run an extension cord and power the device via the USB port.… Read the rest

Exploring my Network with SNMP

Posted on 8 November 2018 by matthannan

I don’t think I’ve made mention yet on this often ignored blog, but I have a new job.

Two new jobs, actually, since the last time I think I talked about jobs here.

I left State Street/Netview back in mid-June. I took a job with a Silicon Valley-based company as a network contractor.… Read the rest

RetroPie Brain Transplant and a New Home

Posted on 26 August 2018 by matthannan

Xbox 360 controllers suddenly stopped working correctly on the new Pi3B+. Some quick Googling revealed this to be an on-going issue for the past few months that only just now filtered down to me. Performed a quick swap back to the Pi3B and everything is working fine.… Read the rest

Making the computer “see”.

Posted on 13 August 2018 by matthannan

I am currently down the OpenCV rabbit hole.
I want to velcro a Rasp Pi to my oil tank and have it “see” how much oil is in there.
I don’t want to see a picture of the meter. That would be too easy.… Read the rest
