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
Netflow and Splunk
Yesterday, I told the tale of getting netflow data out of my EdgeOS router. Once I started actually receiving data, I wanted to get it into Splunk. I figured that I would have to set up a directory for netflow log data from nfdump, then set up a reader to have Splunk ingest the data.… Continue reading Netflow and Splunk
EdgeOS and Netflow
Update: Since I wrote this blog post in 2016, I’ve turned off netflow on my router. Why? Because I upgraded to gigabit fiber, and when netflow is enabled, it throttled my speed to 150 Mb/s or so. Not good! Giving up netflow is a small price to pay for full gigabit speeds. If you do… Continue reading EdgeOS and Netflow
