Byobu (over SSH) Cheat Sheet

I often find myself using Byobu on a Linux machine when connected to it over SSH. In doing so, I've noticed that many of the documented keyboard shortcuts don't work. This can be due to the native PC's OS intercepting certain keys, or possibly other reasons.

Below is a cheatsheet with Byobu features I have found usually work when run over a SSH connection.

Action	Windows + Putty to Ubuntu	MacOS + Terminal to Ubuntu
Help menu	BASH: byobu-config	FN-F1
Create new window	CTRL-a c	CTRL-a c or FN-F2

OAuth 2.0 Token Introspection with NGINX and njs

This configuration enables NGINX to validate an authentication token against an authorization server by using OAuth 2.0 Token Introspection (RFC 7662). This solution uses the auth_request module and the NGINX JavaScript module to require authentication and perform the token introspection request.

By default, the client's authentication token is expected as a bearer token supplied in the Authorization header. If supplied elsewhere in the HTTP request, the $access_token variable must be configured to specify where to obtain the token.

Token introspection requests are authenticated. By default, the $oauth_client_id and $oauth_client_secret variables are used to perform HTTP Basic authentication with the Authorization Server. If only the $oauth_client_secret variable is specified then that value is used

The Digilent JTag uses FT2232, but its configuration EEPROM contains secrete data needed to be recoginzed by Xilinx ISE/Vivado. The following method only works on linux (tested on Ubuntu16.04), but the patched FT2232 doggle also works on Windows. Since WSL1 does not provide USB device access, the following method will not work for WSL1.

DONT use FT_Prog on offical Digilent cable, as it can trash the firmware! The offical eeprom contains secrete data that cannot be handled correctly by FT_Prog.

Here are steps to create a Digilent-like Jtag that can be used in Xilinx ISE and Vivado

Install softwares: sudo apt-get install libftdi1 ftdi-eeprom
Create a file "flash_digilent.conf" with the following content:
