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
2015 Tax Incidence
Hey, it’s tax time again!
Encrypt All The Things
I am a security guy, and my profession is to protect the good guys – all of you – from the bad guys. Although the world is not full of bad guys, there are a lot of them, and the funny thing about information security is that the most poorly-skilled bad guy out there only… Continue reading Encrypt All The Things
Flat ain’t simple
Long time no blog, eh? There’s been a lot of politicking going on lately, what with the presidential campaigns and debates and all, and lots of talk about tax plans. A favorite talking point about a tax plan is the argument that a flat tax will make taxes simpler. A flat tax is many things,… Continue reading Flat ain’t simple
New Sonja Pictures
I don’t always post when I upload new Sonja pictures, but I will in this case. I just uploaded a bunch of pictures from this weekend when we were in Wisconsin with my brother and his girlfriend. They are located here.
EdgeOS and IPv6 Revisited
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
