Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

EdgeRouter Lite + OpenBSD + Goal Zero Yeti solar power pack

Posted 08-10-2017 at 02:23 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

A lot has changed in my home network since I last wrote here on LQ. I moved to a new rental and during the course of re-arranging everything on my network countless times, I started to get a bit irritated with having to constantly shutdown/startup my new firewall. The new firewall, speaking of, is an octeon low-power box, specifically the EdgeRouter Lite, running OpenBSD. Rebooting it is relatively painless, unless you include the speed at which my kids report internet issues (It's an entirely...

Challenge Accepted - Part 1

Posted 07-29-2016 at 08:24 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I'm going to write a short off-topic series on a challenge my wife issued to me the other night. We have two turtles in a 55 gallon aquarium, and I can't seem to keep up with the filter cleaning (turtles are like Oscars and Plecos in terms of waste generation, only 1000x worse...well, ok, Oscars are pretty messy, too). I was complaining about the constant filter maintenance, and my wife asked me why I didn't just build out an aquaponics system on top of the aquarium.

This is pretty...

Another funny network "problem"

Posted 04-23-2016 at 01:33 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I work on the network devices support team at AWS. We provide troubleshooting support for various network-related devices, such as Cisco ISR/ASR/ASA, Juniper SSG/ISG, Fortigate, etc... most of the troubleshooting revolves around AWS Direct Connect and IPSec.

We have a few network labs at AWS that contain many of the devices we support, however, I've always been more of a "hands-on" kind of guy, so I recently purchased a Cisco ISR and a Cisco ASA (2801 and 5505, respectively)....

I have ESP

Posted 04-10-2016 at 10:47 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

Customer calls in, stating he can't get BGP to come up across an IPSec link from a VyOS instance to another region. He explains that this is his first time messing with BGP, and that the session won't establish. We review his configuration, and for a first-timer, I'm really impressed with his understanding of BGP. Clearly this guy has done his homework, as everything, including odd little quirks of BGP, are all accounted for.

"Well, let's sledgehammer the problem. Ping the...

2 != 3, even for very large values of 2

Posted 04-04-2016 at 06:00 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

Spent the past 20 minutes troubleshooting an OpenVPN issue.

Problem: OpenVPN client connects, pulls an IPv4 address, but does not get route information. Manually added routes don't allow ping.

Solution: tap devices cannot talk to tun devices, at least not directly/natively. tap devices are layer 2. tun devices are layer 3. 2, no matter how close it gets to 3, is simply not 3. (ARP tries hard to prove otherwise, but as there is no such thing as a L3 header in...
