RoganDawes / read_serial.py

Created March 3, 2016 15:50

Simple python script to read two serial ports at the same time. Good for snooping on bidirectional comms!

	#!/usr/bin/python3

	import serial, time, sys, threading
	from colorama import Fore, Style, init as colorama_init

	colorama_init()

	# lock to serialize console output
	lock = threading.Lock()

RoganDawes / masscan_bin2list

Created October 14, 2018 13:27

Convert Masscan bin files to a series of nmap invocations

	#!/bin/sh

	# Typical invocation would be:
	# masscan_bin2list masscan.bin \| parallel
	#
	# Example output from masscan_bin2list:
	# nmap -sV -Pn -vv -n -p 443,80 -oA 10.0.0.1_V 10.0.0.1
	# nmap -sV -Pn -vv -n -p 135,139,445 -oA 10.0.0.2_V 10.0.0.2

	masscan --readscan $1 -oL - \| \

RoganDawes / pre-commit-mvn.sh

Last active May 7, 2019 08:18

Run maven on a clean directory, reflecting ONLY what will be in the commit, and excluding any other files in the working directory that might affect the build

	#!/bin/bash
	echo "running pre-commit hooks"

	STAGED_FILES_CMD=`git diff --cached --name-only \| grep -E "(\.java$)\|(pom.xml)"`
	# Determine if a file list is passed
	echo "INPUT: $#"
	if [ "$#" -eq 1 ] ; then
	oIFS=$IFS
	IFS='
	'

	# /usr/share/usb_modeswitch/2001:ac01

	# Run manually if required using:
	# usb_modeswitch -v 0x2001 -p 0xac01 -c /usr/share/usb_modeswitch/2001:ac01

RoganDawes / TeensyMonitor.ino

Last active October 23, 2020 13:56

Some Quick and Dirty python code for reading from two serial ports at once. Also, a Teensy sketch for doing the same using actual simultaneous UARTs.

	#include <elapsedMillis.h>

	#define PIN_D2 2

	#define MAX_BUFFER 16
	uint8_t buffer1[MAX_BUFFER], buffer1pos = 0, buffer3[MAX_BUFFER], buffer3pos = 0;
	char buffer1prefix[] = "E> ", buffer3prefix[] = "A> ";

	elapsedMillis TimeSinceRead;

RoganDawes / currentcost.h

Created April 8, 2021 07:41

ESPHome configuration for CurrentCost Envi XML parsing and reporting. Uses the RapidXML Header-only library to parse the XML. Works on an ESP32, ESP8266 seems insufficient for the task.

	#include <string>
	#include "esphome.h"
	#include "rapidxml/rapidxml.hpp"

	static const char *TAG = "currentcost";

	class CurrentCostSensor : public Component, public UARTDevice {
	public:
	Sensor *ch1 = new Sensor();
	Sensor *ch2 = new Sensor();

RoganDawes / dnsmasq_log.pl

Last active March 29, 2025 00:48

Script to ingest operwrt syslogs, build up a map of DNS name lookups to the resulting IP address, and then replace the IP address in subsequent log entries with the corresponding name that was queried. This currently focuses specifically on log entries that match the expression "REJECT wan out", but could certainly be adjusted to work with other…

	#!/usr/bin/perl -w
	# Script to process router log file to list dnsmasq DNS lookup entries and
	# Kernel DROP entries to correlate which DNS names are being dropped by the
	# firewall.
	#
	# dnsmasq correlates multiple log entries using a random key, and these can
	# be interleaved with other log entries.
	#
	# The idea is to sort the entries according to the key, but in order of time
	#

RoganDawes / fud.c

Created June 23, 2022 07:40

C code implementing Singe's Fear Uncertainty and Doubt protocol

	#include <stdio.h>

	int main() {
	int i, n, m ;
	scanf("%d", &n);
	int o = n;
	while ( n - o < 999999999 ) {
	char c = '2';
	if ((n%3) == 0) {
	c = '0';
