XCP-ng USB passthrough tools

A set of command line tools and a service to make setting up passthrough USB devices easier:

add-custom-usb-policies - script to store and apply custom USB policies required for specific devices
attach-usb-devices - script and service to automatically connect USB devices to VMS when XCP-ng boots up
plug-usb - attach a physical USB device to a VM in one command
unplug-usb - remove a physical USB device from a VM in one command

To set up, copy the files onto your server and run install.sh to copy everything and set up the service.

Programming Media Keys on the Ducky One 2 Skyline

To use media keys on the Ducky One 2 Skyline, you must record a macro to bind the media function to a hotkey combination, i.e. Fn plus some key.

Example

Important: In the instructions below, "Press X+Y+Z" means press and hold key X, press and hold key Y, press and hold key Z in that order, and then release all three.

As an example, to bind Fn+PgUp to the play/pause media function:

Bash shebang

Commenting

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Alternatives to the "Atlassian Stack"

Fuller stack alternatives (replaces at least two of the Atlassian stack)

Overview

This is a bash script that will automatically turn your wifi off if you connect your computer to an ethernet connection and turn wifi back on when you unplug your ethernet cable/adapter. If you decide to turn wifi on for whatever reason, it will remember that choice. This was improvised from this mac hint to work with Yosemite, and without hard-coding the adapter names. It's supposed to support growl, but I didn't check that part. I did, however, add OSX notification center support. Feel free to fork and fix any issues you encounter.

Most the credit for these changes go to Dave Holland.
