+
+It's a breezy autumn Sunday. It is warm, the sky is clear and after this past
+week the trees are certainly showing the season. Nights have been cool and the
+forecast says the days will soon be as well. A favorite soup recipe is on the
+menu for tonight's dinner and I'd hoped to make baguettes to go with it, but
+I'll be damned if I can get dough to agree with me today. After two botched
+attempts, looks like I'll be running to the bakery before dinner.
+
+Baking foibles aside, I have had some luck lately making a [Raspberry Pi
+Zero](https://www.raspberrypi.org/products/raspberry-pi-zero-w/) into a [USB
+Ethernet Gadget](https://learn.adafruit.com/turning-your-raspberry-pi-zero-into-a-usb-gadget/ethernet-gadget)
+While I was able to do most of what I wanted following Lady Ada's instructions,
+I did encounter a few gotchas, plus I wanted to do the same thing but running
+[Kali Linux](https://www.kali.org) instead.
+
+## Why do I want this?
+
+Typically I do most of my work on my now-aging MacBook Pro, running Kali Linux
+on a virtual machine. This is a typical setup and generally works just fine.
+Where it falls down is when I'm playing with my
+[RTL-SDR](https://www.rtl-sdr.com/) software defined radio, or my Great Scott's
+[YARD Stick One](https://greatscottgadgets.com/yardstickone/). For some reason I
+just can't get the devices to behave or to stay online, a problem I haven't had
+running Linux on the metal. I've also had occasional trouble running wifi
+attacks on external hardware. While I do intend to move back to a Linux laptop
+in the foreseeable future, it would be nice to have a small, easy-to-use Kali
+machine in my pocket when the need arises. The Pi Zero also lends itself to some
+naughty use cases, what with it's super-small form factor.
+
+So, I'm going to document here exactly how I get my Pi setup and configured, up
+to and including getting [Kismet](https://www.kismetwireless.net/)set up for
+portable WiFi mischief. For the remainder of this write-up, I'm assuming you are
+running on an up-to-date version of MacOS. Linux should be similar up to a
+point, but you Window$ users are on your own.
+
+## Download and flash MicroSD
+
+First off, download the latest [Kali ARM
+image](https://www.offensive-security.com/kali-linux-arm-images/) for the
+Raspberry Pi Zero/Zero W. Before you transfer the image to your SD card, verify
+it's hash against the one presented next to the image's torrent link.
+
+```shell
+$ shasum sha256sum ~/Downloads/kali-linux-2019-3-rpi0w-nexmon-img-xz/kali-linux-2019.3-rpi0w-nexmon.img.xz
+0c06f7220f585552e57bcd62a683d4ef6a6409cfd6ea3d63ce96c39792acd918 /Users/adam/Downloads/kali-linux-2019-3-rpi0w-nexmon-img-xz/kali-linux-2019.3-rpi0w-nexmon.img.xz
+```
+
+While you can use `dd` to write the image to your SD card, I've found
+[balenaEtcher](https://www.balena.io/etcher/) to be easier and much faster doing
+basically the same thing. They must know exactly which switches to flip. In any
+case, select your verified image and target SD card and click "Flash!"
+
+## Configure USB gadget
+
+Flashing your card will take a bit, I think it took about 15 minutes to flash
+and validate on my machine, your mileage may vary. Once that's done, eject and
+re-insert the SD card. The next couple of steps will be done directly to files
+on the root of the card's filesystem. These steps are basically verbatim from
+Lady Ada's tutorial referenced above and below.
+
+### Edit config.txt & cmdline.txt
+
+My SD card mounted at `/Volumes/NO\ NAME/`.
+
+First add `dtoverlay=dwc2` to the last line of `config.txt`.
+
+```shell
+echo "dtoverlay=dwc2" >> /Volumes/NO\NAME/config.txt
+```
+
+Next open up cmdline.txt and at the end of the first line, after `rootwait` add
+`modules-load=dwc2,g_ether`.
+
+```shell
+dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2
+rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait modules-load=dwc2,g_ether
+```
+
+### Enable SSH
+
+Super easy, enable SSH into the Pi be dropping an empty file called `ssh` at the
+root of the SD card:
+
+```shell
+touch /Volumes/NO\ NAME/ssh
+```
+
+Now we should be able to boot up and ssh into our Pi. Eject your SD card from
+your host computer, insert it into your Pi, and plug a USB cable from your
+computer to the Pi. Be sure to use the port labeled "USB" and not the one
+labeled "PWR".
+
+## Enable networking
+
+## Update Kali
+
+## Install Kismet
+
+## Configure wireless device

+Title: Malgranda Temoj ke Elĉerpas Mian Atenton

+
+
+Hieraŭ mi ricevis libron en la poŝto, [Ne Ekzistas Verdaj
+Steloj](http://www.esperanto.net/literaturo/novel/novlibr/neverdstel.html) per
+Liven Dek. Mi aĉetis la libron antaŭe mi vidas ĝin antaŭ tri aŭ kvar monatoj ĉe
+esperanta renkontiĝo. Mi ŝatas la mallongan aranĝon de le libro ĉar ĝi estas pli
+facile ol longaj libroj, kiam mi lernas. Dum mi legas kaj skribas sufiĉe bone,
+mi bezonas multe pli praktiko. La libro havas sesdek rakantojn, kiuj havas nur
+unu aŭ du paĝojn.
+
+Ĉar mi ne havas komunomo kun kiu praktiki paroladon, estas malfacila daŭrigi
+mian esperanton. Iun tagon, mi ricevis mesaĝon sur Amikumu de iu en la areo, ke
+li kaj iuj uloj renkontiĝis en proksima parko. Mi iris kaj trovis du junoj
+knaboj, eble dudek jaroj. Ni parolis por cirkaŭ hora kaj mi strebis plej bone
+paroli. Mi ne pensas ili plu vokos, sed ĝi estis amuze.

+## I've let a month go by...
+
+It's not that I haven't been writing, but I have had trouble finishing things
+lately. It's been easy to get caught up in the day-to-day, and maybe that's a
+good thing. I don't know if I should get caught in the industrial mindset trap
+of measuring my self worth by my productivity.
+
+I do have a couple more write-ups in the works, with a couple of minor snags
+I'll need to work out before I publish them here, perhaps in an abbreviated
+form. I tend to write down a lot of what I work on while I'm working, and
+sometimes things don't work out the way I'd intended.
+
+
+## Kali Linux Pi Zero Wifi Attack Sidecar
+
+For example, I'd been working on a Kali Linux based, Raspberry Pi Zero W USB
+Ethernet Gadget. You may have read about [turning a Pi Zero into a USB
+Gadget](https://learn.adafruit.com/turning-your-raspberry-pi-zero-into-a-usb-gadget/ethernet-gadget)
+as written by Lady Ada. This works very well on stock, light Raspbian, but I'm
+afraid that on a Kali image, even with the [re4son
+kernel](https://whitedome.com.au/re4son/download/re4son-kernel-current/),
+doesn't seem to have everything you need to do the same. This means that I
+haven't been able to connect privately via ssh over USB, which I felt made for a
+really cool, portable gadget. I also found that the Pi Zero had trouble
+delivering enough power to my external ALFA wifi adapter, which I believe is the
+cause for some pretty predictable freezes of the system any time I try to
+interact with, or even list, that device. When I can, I'll try to summarize what
+I encountered and put it up here.
+
+
+## Ĉu vi legas la Esperanton?
+
+I've started one article a translation of another into Esperanto. My study of
+the language tends to ebb and flow, and I'm ebbing right now for sure.
+Translating technical articles into Esperanto proves to be an interesting
+challenge, even with the help of [Komputeko](https://komputeko.net/). It's a fun
+process, but time consuming. I've also enjoyed trying to get my thoughts out as
+an Esperanto-first exercise. Again, put it on the to-do list. Or the drafts
+folder. Whatever.
+
+
+## Toys!
+
+I haven't been totally unproductive! Lately I've been refreshing some old
+hardware and giving existing systems some much needed updates.
+
+For the last couple of years I've been running my own, home built gateway and
+firewall based on OpenBSD and pf. It's been a pretty bare-metal setup with no
+additional packages after the initial install. I learned to configure `pf`
+myself, as well as to set up unbound as my local, caching, forwarding DNS
+server that sent requests via DNS over HTTPS to 9.9.9.9 and 1.1.1.1.
