Phone Home

Have all of your devices call in, and know when they were online last

Setup

1. Install deps:

yarn

2. Create some certificates. I like self-signing

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

3. Run the server

node server

Interacting with the server

Do it lazily with cURL!

Updating

curl -X POST -H "authorization: secrets don't go on github" https://SERVER_URL:5001/key/laptop -k

Retrieving All Records

curl -H "authorization: secrets don't go on github" https://SERVER_URL:5001/all -k

Running on Startup

Create a Systemd service unit:

[Unit]
Description=Phone Home Service

[Service]
ExecStart=/path/to/curl_script

[Install]
WantedBy=multi-user.target

• Save it under /etc/systemd/system/phone-home.service
• Start the service sudo systemctl start phone-home.service
• Enable it! sudo systemctl enable phone-home.service
