This will become a short tutorial on how to achieve higher bandwidth on a residential (german) Vodafone DOCSIS internet connection.

A flaw in Vodafone's modem activation process allows for simultanous operation of two modems on one contract:

Vodafone-owned CPE (e.g. "Vodafone Station")
Customer CPE (TC4400, Fritz?!Box 6660, etc.)

On a low-loaded DOCSIS 3.1 segment, I am able to achieve 1900 MBit/s download and 95 MBits/ upload bitrate by bundling both modems using MPTCP

Use non local IPv6 with GoLang (e.g. to bypass Ratelimit)

You need:

IPv6 addresses (and a static route)
A "to local" route
The address range configured on the loopback interface
net.ipv6.ip_nonlocal_bind=1

Use Adobe Acrobat or Okular to view the PDF. pdf.js does not work.

Steps to reproduce

# Download some gif
curl 'https://media4.giphy.com/media/mCCpMOJCiiLbdBWuv3/giphy.gif' > some.gif

# Split into single frames
mkdir output
convert -coalesce +adjoin some.gif output/tmp.png

	#!/bin/bash

	# Database parameters
	HOST="crt.sh"
	PORT="5432"
	USER="guest"
	DB="certwatch"

	# File to store the data
	OUTPUT_FILE="certificates.csv"

	#!/bin/bash

	if ! command -v curl &> /dev/null; then
	echo "This script needs curl. Please install curl."
	exit -1
	fi

	if ! command -v jq &> /dev/null; then
	echo "This script needs jq. Please install jq."
	exit -1
