ConMon

This is a Elixir Nerves application to monitor and log Internet downtime by pinging a list of hosts.

Prerequisites

• Elixir
• Nerves

Targets

Nerves applications produce images for hardware targets based on the MIX_TARGET environment variable. If MIX_TARGET is unset, mix builds an image that runs on the host (e.g., your laptop). This is useful for executing logic tests, running utilities, and debugging. Other targets are represented by a short name like rpi3 that maps to a Nerves system image for that platform. All of this logic is in the generated mix.exs and may be customized. For more information about targets see:

https://hexdocs.pm/nerves/targets.html#content

Getting Started

• Clone repository

• To start your Nerves app:

  • export MIX_TARGET=my_target or prefix every command with MIX_TARGET=my_target. For example, MIX_TARGET=rpi3
  • Install dependencies with mix deps.get
  • Create firmware with mix firmware
  • Burn to an SD card with mix firmware.burn
  • OR run on host with iex -S mix

• To ssh to the pi and access console on your local network you can run: ssh con_mon.local

• To check logs: Run ConMon.StateServer.get_state in the iex console

Note

After ssh use this to auth pi with firewall

a = "{\"user\":\"USERNAME\",\"submit\":\"Login\",\"passwd\":\"PASSWORD\",\"actualUrl\":\"8.8.8.8\"}"
:hackney.post("http://172.16.1.254/userSense", [], a, [])

After update this is the new way to auth:

headers = [
  {"Host", "172.16.1.254"},
  {"Connection", "keep-alive"},
  {"Content-Length", "76"},
  {"Cache-Control", "max-age=0"},
  {"Origin", "http://8.8.8.8"},
  {"Upgrade-Insecure-Requests", "1"},
  {"Content-Type", "application/x-www-form-urlencoded"},
  {"User-Agent",
   "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36"},
  {"Accept",
   "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3"},
  {"Referer", "http://8.8.8.8/"},
  {"Accept-Encoding", "gzip, deflate"},
  {"Accept-Language", "en-US,en;q=0.9"}
]
url= "http://172.16.1.254/userSense?user=USERNAME&passwd=PASSWORD&otp=&submit=Login&actualurl=http%3A%2F%2F8.8.8.8%2F"
:hackney.post(url, headers, [], [])
