About a week ago I noticed that my browsing was no longer using IPv6. How, you ask? I use IPvFoo, a Chrome extension that shows you in your address bar whether you are browsing a site using IPv4 or IPv6. True, only Google and Facebook are the sites that I browse regularly that use IPv6,… Continue reading EdgeOS and IPv6 Revisited
Monitoring my UPS with Splunk
Last time, I had set up my UPS monitoring software on my CentOS logging server. But I wanted more: what good is having a UPS if I can’t monitor things like voltage, battery charge, and load on an ongoing basis? Of course, the answer to this is to log to Splunk, which is what I… Continue reading Monitoring my UPS with Splunk
Installing NUT on CentOS
Getting a UPS (Uninterruptible Power Supply) has long been on my tech wish list, so that I could keep my network and logging server up and running during transient power outages. Fortunately, aside from a brief outage right after we bought our house three years ago, power has not been a problem, unlike when I… Continue reading Installing NUT on CentOS
mDNS Update
My last update on getting Bonjour/mDNS working on my network ended with “If it ain’t broke”… Sadly, the broke state cropped up at some point between then and now. Home sharing with the Apple TV was no longer working, and nothing had changed on my end to break it. Apple may have changed things on… Continue reading mDNS Update
Minnesota Tax Incidence 2015
The 2015 Minnesota Tax Incidence study is out. Since I last posted about this two years ago, not much has changed. Details below:
Splunk Reporting: Port Scans
It’s been a while since I’ve done some Splunk work on my home network, but lately I’ve been thinking about port scans, specifically about reporting on port scans against my environment. I’m not terribly worried about people scanning my network since it is quite locked down, but why not check on it to see if anything interesting… Continue reading Splunk Reporting: Port Scans
Crypto 1
I’ve been taking my first MOOC via Coursera, Crypto 1, taught by Dan Boneh. I’ve just finished up the final, and it’s been a fantastic experience, something I’d recommend to anybody with an interest in the subject. This course is more about theory that how to implement crypto in the real world, but the theory… Continue reading Crypto 1
2014 Tax Incidence
Tax time is here, and that means it’s time to calculate our 2014 tax incidence below…
Replacing Chef’s self-signed certificates
Having gotten my home network and logging to a point where I wanted it, my next project was going to be Chef. Life intervened before I got too much involved with Chef, but now that things are approaching a sense of normalcy, I’m trying to pick up where I left off. My ultimate goal is… Continue reading Replacing Chef’s self-signed certificates
Bonjour!: mDNS and iTunes Home Sharing on EdgeOS
Ever since I’ve set up my home network, Home Sharing hasn’t worked between our Apple TV and my desktop computer. It’s been a minor annoyance that I really didn’t look into before now, but I had some time yesterday to troubleshoot it and get it working just in time to watch Little Women, which Julia… Continue reading Bonjour!: mDNS and iTunes Home Sharing on EdgeOS
