== Introduction
|
||||
|
||||
Hello! My name is Brent Saner, and I have a passion for technology.
|
||||
I don't mean I enjoy playing with the latest gadgets, I mean a *passion*.
|
||||
|
||||
I read RFCs and man pages for fun (so much so that
|
||||
https://git.square-r00t.net/OpTools/tree/ref/rfc.py[I wrote an RFC client^] - before I found out that the IETF already
|
||||
https://tools.ietf.org/inventory/reading-tools.shtml[has several^], oops). I have a
|
||||
https://git.square-r00t.net/[large amount of projects^] I work on in my free time. I have a VM lab (almost a necessity
|
||||
if one works from home), and my home network is segmented into five different VLANs, four different WLANs tied to a
|
||||
unique VLAN each, on-site and remote backups, PXE-bootstrapped https://ipxe.org/[iPXE^], with 10Gbps house backbone
|
||||
using 802.1X backed by RADIUS and LDAP, all with a full x86_64 Linux 1U as my border device. For a home network.
|
||||
|
||||
When I say "passion", I mean it.
|
||||
|
||||
With this, combined with my 18 years of professional Linux/UNIX experience (21 years hobbyist), I've learned a few
|
||||
tricks around the ol' rodeo. Because of my adherence to and knowledge of best practices, care for forward-thinking, and
|
||||
sheer joy I take in solving potentially difficult problems, it is my goal (and particular knack) to get your company's
|
||||
infrastructure and services smooth and stable while retaining flexibility for vast growth.

== Samples of Work
|
||||
|
||||
Since I focus more on operations/administration than development, most of my "samples" can be found via
|
||||
administration *theory*. This is expounded upon a great deal in https://sysadministrivia.com/[my podcast^].
|
||||
|
||||
Occasionally, however, I also write documentation for our demographic (mostly other Linux sysadmins). Samples of these
|
||||
can be found here:
|
||||
|
||||
* https://sysadministrivia.com/news/RSYNC[RSYNC^] (not RSYNC over SSH)
|
||||
* https://sysadministrivia.com/news/howto-podcast[Podcast hosting^] (technical details)
|
||||
* https://sysadministrivia.com/news/howto-borgserver[Deploying a backup server with privilege separation^]
|
||||
* https://sysadministrivia.com/news/howto-grubrescue[Booting a rescue ISO directly from GRUB^]
|
||||
|
||||
However, I do have a lot of Python (and some Bash) written. Examples include:
|
||||
|
||||
* https://github.com/johnnybubonic/BDisk[A liveCD/liveUSB/iPXE image creator^] (in the process of a rewrite)
|
||||
* https://github.com/johnnybubonic/aif-ng[A preseed/Kickstart-like facility for Arch Linux^] (in the process of a rewrite)

||||

|

repositories can be found https://git.square-r00t.net/[here ^].
