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.

Adventures in OpenBSD softraid

Posted Yesterday at 09:55 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

Hosted at one of the small-ish cloud providers I have a small VM that I recently resized. Along with a small bump in RAM (for the same price), I was able to secure a bit more storage space. Win-win, right?

I have an OpenBSD RAID volume on the server. Built within this RAID volume is a softraid crypto virtual disk. I decided to resize this crypto volume, so I've booted the server up with the ramdisk kernel. First, I resized the physical volume's layout, so a quick "fdisk...

"Are we there yet?"

Windows has this nasty habit of spamming a dhcp server with DHCPINFORM messages unless the dhcp server provides a proxy auto-configuration script. As I've not yet found a way to make Windows stop doing this, I've set up the following in my dhcpd.conf:

Code:
option autoproxy-script "http://10.42.0.11/wpad.pac";
The above is for OpenBSD dhcpd. For dnsmasq:

Code:
dhcp-option=252,http://10.42.0.11/wpad.pac
Or for ISC dhcpd:

Code:
option

Keeping Route53 updated

Posted 08-12-2018 at 01:54 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)
Updated 08-14-2018 at 06:36 PM by rocket357 (typo!)

I have dual ISP connections at home due to the uptime requirements of working from the home office. It's nice sometimes to be able to connect back to the home office when I'm out (I've found various reasons over the years heh), and memorizing two ips is, well, twice as difficult as memorizing one ip.

The problem is, both my ISP uplinks are DHCP-assigned. They tend to be stable, but they could change at a moment's notice. And if working in tech has taught me anything, it's that...

u-boot is infuriating

Posted 08-08-2018 at 05:36 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

Spent the better part of the night screwing around with installing OpenBSD on a Raspberry Pi 3 B+ (note the subtle extra character right at the end, there). It's irritating that a device can go from Version "3 B" to "3 B+" and so much changed. Spent a good bit of time goofing around with dtb files and trying to find the magic combination that would allow me to boot. Got close a few times, but the ethernet port refused to show up.

Ok, perhaps this is just an...

Architecture of a switch

Posted 07-02-2018 at 11:25 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I was setting up smokeping in a docker container on a recently-repurposed machine on my home network, as I recently downsized from a Cisco 3560 core switch to two Ubiquiti US-8s (primary reasoning: the US-8 handles vlans like a champ, and I can run them both on my battery bank with a lighter wattage impact than the 3560). Smokeping was reporting some odd numbers which illustrates a quirk about switches/routers designed for management purposes, so I thought I'd write here about the effect and what...
