Many years ago, I wrote a blog post about monitoring my UPS with Splunk. Since then, I’ve moved away from Splunk to the Elastic stack. Fortunately, moving that monitoring over was pretty much a breeze. The information is still coming from upslog, which is bundled in with nut. FIrst, I configured nut to define the… Continue reading Monitor your UPS with Logstash the easy way
How to replace Unifi Network’s default TLS certificate
In this blog post, I explain how to replace the default Unifi Web certificate stored in a Java keystore with your own certificate.
Easily generate an HTTPS certificate for Kibana (with bonus AI)
As part of my upgrade to Elastic 8 and modifications to Kibana, I also decided to add a TLS certificate so I could encrypt my traffic with HTTPS. Not because I’m terribly worried about some hacker listening in on my super-secret Kibana traffic, but because these days there’s no reason not to encrypt everything. In… Continue reading Easily generate an HTTPS certificate for Kibana (with bonus AI)
How to configure Kibana behind an nginx proxy
In my previous post about upgrading to Elastic 8, I signed off with the promise of sharing how I put Kibana behind an nginx proxy. Here’s the post on how I did that, and what I did to make it work after a few hours of messing around with various settings. If you want the… Continue reading How to configure Kibana behind an nginx proxy
My almost-effortless upgrade experience (and lessons learned) with Elastic 8
I had a relatively painless upgrade from Elastic 7 to Elastic 8, and your experience can be even better if you keep a few things in mind based on my lessons learned.
Graphing CPU temps using CoreTemp and Elasticsearch
Recently I purchased a new computer case to replace the ancient giant one I bought in 2009. The various fans had stopped working, and I realized that I no longer had a large number of external drives like DVD drives and so forth, so when Newegg had that case on sale, I uncharacteristically made an… Continue reading Graphing CPU temps using CoreTemp and Elasticsearch
Adding a SAN to a certificate using OpenSSL
A long time ago, I set up an internal PKI so I could create my own TLS certificates to add to internal devices and HTTPS servers. I used this primarily for my EdgeOS router since that was the main device I would log into that would give me a warning about untrusted certificates. That was… Continue reading Adding a SAN to a certificate using OpenSSL
Investigating a WordPress Compromise
It’s been a while since I updated this blog, and this lack of attention (and falling behind a few versions in WordPress) led to this very site getting hacked! Fortunately, I was quickly alerted to it thanks to Google, and if nothing else, this presents an interesting case study in investigating what happened. Full details… Continue reading Investigating a WordPress Compromise
A few thoughts
So we’ve electioneered. And some things have happened. Unsolicited thoughts below the jump.
PKI Revisited
A little more than two years ago, I set up a PKI and did a post on it. The main goal was to get a certificate on my EdgeOS router to get proper HTTPS support without the annoying red X. When I did it, however, I didn’t do it quite right, and so I decided… Continue reading PKI Revisited
