LinuxQuestions.org - Musings on technology, philosophy, and life in the corporate world

Hi. I'm jon.404, a Unix/Linux/Database/Openstack/Kubernetes Administrator, AWS/GCP/Azure Engineer, 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: *nix.

"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

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 04:36 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 10:25 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...

This...this should never happen

user@host:~$ sudo reboot
[sudo] password for user:
Failed to start reboot.target: Connection timed out
See system logs and 'systemctl status reboot.target' for details.

Words cannot express how infuriating and depressing that error message is. Just turn the &$(&%^Y(#@ computer off!

Edit: It gets ever more obnoxious:

Failed to get properties: Connection timed out
