Books Read: 2018

Using my (now aged) Kindle, I do a fair bit of reading. For some reason, whenever I finish a book I put it into a folder on my Kindle named for the current year. These folders exist only on the Kindle itself, so I thought I might start to keep track of them here on the blog.

At the end of 2017 I was reading a lot of memoirs of people who moved into the wilderness, both in recent years and in centuries past. That continued into 2018 and the first book I read was:

Winds of Skilak, by Bonnie Ward
This was an excellent book, written by Bonnie, about her and her husband’s journey leaving Ohio and moving to an isolated island on Skilak Lake in Alaska.… Click here to read more!

Setting Up Nagios – Working with Cisco’s CIMC

This was far more challenging than it needed to be. Cisco makes some SDK’s available for use with Nagios but I was totally unable to make the system see them. They are just Python packages so I didn’t expect much trouble, but I was totally at a loss. I thought, initially, that the issue was that the installer dumped the files into /usr/lib/python/site-packages/ instead of the 64bit path /usr/lib64/python/site-packages/ but no amount of copying and permissions changes made the system able to see the dependencies. For those interested, here is a link to the Cisco Nagios tools (from 09/2017) Nagios Plug-Ins for Cisco UCS.… Click here to read more!

Setting Up Nagios – Installing on Centos 7

Long story short, I changed jobs about 6 months ago and found myself in a new position without any appreciable monitoring of the hardware for which I’m responsible. That needed to change as soon as I started to have time to put some hours into it. I did a little testing and poking around with some other monitoring tools but kept coming back to Nagios as the right choice, despite the mountain of work involved in setting it up. There is such a large community of help and plugins available for it, plus it’s a tool I’ve used at other jobs for many years.… Click here to read more!

Libresonic on Centos 7 with SSL

I’ve been a happy iTunes Match user since the service was introduced. I have a large music collection and I don’t always want to dedicate the required amount of iPhone and computer storage to keeping it available all the time on all my devices. iTunes Match lets Apple deal with storing the whole thing and allows me to just download what I want on a given device or stream music I own to any device I’d like. It’s been $25/year well spent.

That being said, with streaming music plans taking over the market, I can’t imagine Apple’s going to want to offer this service forever, plus I prefer to self-host as much of my digital needs as possible.… Click here to read more!

When the Photo Bug Bites

I remember the first time I saw a moment that I knew I had to photograph. I wonder if other photographers are the same.

I was in Maine, spending a weekend with a friend at his lake side cabin. I woke up on a cool late autumn morning and the whole lake was covered in rising mist. The water was much warmer than the cool dry air and up came the moisture.

My only camera was a 3 megapixel ‘Kodak Easy Share’ I had gotten for Christmas a few years before. This was turn of the century, inexpensive, pocket camera technology at its most average.… Click here to read more!

Automated Backups of OpnSense

I use rsnapshot, on Centos 7, to manage the vast majority of my backups across a myriad of linux servers both within my network and across the globe. I’ve never blogged about the entirety of that process, but I wanted to post a quick note about how I use rsnapshot to also backup the configuration of my router.

Until recently, I had been using this process to backup my pfSense routers. With my switch to OPNsense though, I was pleased to see the process is the same.

Basically, we just need to make a copy of a single folder on the machine, ‘/conf’, which is located right off of the root on both pfSense an OpnSense.… Click here to read more!

Cleaning up old Logs on Centos 7

As often happens with computers of all types, log files build up over time. Generally speaking, the operating system will rotate these logs, which means it breaks them up into chunks, but it isn’t usually set to remove the old chunks. Over time, those log files can start to add up.

I am giving some thought to changing the provider of the VPS that hosts this web page, since performance is not consistent and the VPS is not very reliable, and I was curious to know how much disk space I needed for the system to run well. After doing some light clean up on the system I did a check to see where on the disk I was using the most space.… Click here to read more!

Interesting Failure Modes – SD Card Arching

I’ve been using Raspberry Pi computers for several years. A few months ago the Raspberry Pi B I had hooked up to my TV and running OpenElec, stopped working. The Pi was locked up and then wouldn’t reboot when I pulled the power cord.

It’s an original B model, with just two USB ports, so I didn’t think much of it. I prepped and put in place a replacement Pi, also running OpenElec, and threw the Pi into a drawer for further inspection..later. I got 4 years faithful service from a $35 computer so I wasn’t complaining.

Some weeks later, I had an idea that I wanted to use a Raspberry Pi for so I grabbed the questionable unit and got to work.… Click here to read more!

How To: A Clean install of Windows 7 in 2016

Maybe I’m alone here, but I still have occasion to install Windows 7 from time to time. For a while, that was no big deal; Install the OS, update, update, update and you’re good to go. Lately though, the process has become far more cumbersome. Not only does the process take ages to complete, but when you’re done its always nagging you to update to Windows 10. What follows is my process for getting this done without too much hassle.

Firstly, I’ve not created anything new here. I’ve simply found a series of tools and bit of information online that helped me along the way so I’m compiling it here for my future benefit.… Click here to read more!

Install Centos 6 on a Non-PAE Machine

I have a Thecus N5200 that was modified to have a VGA port. Though the machine will run a variety of current Linux distributions, I wanted it to run Centos 6. Unfortunately, the N5200 doesn’t support PAE, which Centos 6 requires.

The first major problem is that a Non-PAE machine won’t even boot the Centos installer CD/DVD. You have to find some way around that. There are several ways to get around that but they are all quite complex and time-consuming. Plus, as time goes on they work less and less. The old software needed is harder and harder to find.… Click here to read more!
