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 / 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 / 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;
