These are my notes for connecting to a meraki client vpn from ubuntu 16.04. This configuration assumes you are using a psk for the ipsec auth.

How to configure Bash Completion on Mac for Docker and Docker-Compose

Copied from the official Docker-for-mac documentation (thanks Brett for the updated doc pointer):

Install shell completion

Docker Desktop for Mac comes with scripts to enable completion for the docker, docker-machine, and docker-compose commands. The completion scripts may be found inside Docker.app, in the Contents/Resources/etc/ directory and can be installed both in Bash and Zsh.

Bash

Bash has built-in support for completion To activate completion for Docker commands, these files need to be copied or symlinked to your bash_completion.d/ directory. For example, if you installed bash via Homebrew:

	## Configure bro to write JSON logs
	mkdir -p /opt/bro/share/bro/site/scripts
	sudo tee /opt/bro/share/bro/site/scripts/json-logs.bro << EOF
	@load tuning/json-logs

	redef LogAscii::json_timestamps = JSON::TS_ISO8601;
	redef LogAscii::use_json = T;
	EOF

	sudo tee -a /opt/bro/share/bro/site/local.bro << EOF

	//Now with less jquery
	//1) go to your my-list page, and scroll to the bottom to make sure it's all loaded:
	//http://www.netflix.com/browse/my-list

	//2) Next, paste this in your developer tools console and hit enter:
	[...document.querySelectorAll('.slider [aria-label]')].map(ele => ele.getAttribute('aria-label'))
	//or use this to copy the list to your clipboard:
	copy([...document.querySelectorAll('.slider [aria-label]')].map(ele => ele.getAttribute('aria-label')))

	# Encrypt STDIN and provide a password(prompt)
	echo "message" \| openssl enc -aes-256-cbc -a

	# Decrypt STDIN and provide a password(prompt)
	echo "encrypted" \| openssl enc -aes-256-cbc -a -d
