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.

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:

Ubiquiti Controller: Devices listed as "Disconnected"

Had this problem after an ip change for my controller. I have an EdgeRouter Lite with 2 US-8's hanging off of eth1 and eth2, and for silly reasons I needed to move my controller laptop from one US-8 to the other. Once I did that, the US-8 it was previously attached to and the AP-AC-LR attached to the old US-8 showed up in "Disconnected" state in the controller software (eth1 and eth2 are not bridged, currently. If they were, it would have avoided this issue).

A cursory...

The little outlet that couldn't

Hey there! I haven't posted in a long while, so I thought I'd share a funny story that happened to me last night.

As some of you know, I left my job at $big_corp to head back to saner pastures. I found a really nice remote job working with Openstack. I worked from home some while at $big_corp, but the quality of power and network at home wasn't a deal breaker, given that I could easily commute to the corp office if the home office turned into a three-ring circus. Now, however,...

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...
