What is this for?

I needed a tool to track user actions while testing new equipment and configurations.

This tool allows me to inject notes into the local network traffic, which I monitor with TCPdump or Wireshark. By filtering the notes from the traffic, I can create correlation between actions I took as a user and resulting changes in the network traffic

Example messages I often send with this tool are something like "Started registration" or "Rebooted device"

How to see the notes in network traffic?

sudo tcpdump -i [network device] -A | grep -a "netnote_message"

How it works?

By default, this form sends the contents to `example.fi`, but you can change the address to anything you wish, or select "random" to randomize the domain each time the message is sent.

Start by monitoring your network traffic, for example using TCPdump. Then type something to the input field and press "Send" to send it.

Is it safe?

This site has no tracking, cookies, or any other form of user monitoring. All messages are sent by your browser, so apart from the server you selected, there is no servers or backend to store or collect the messages.

There is no encryption applied on the sent message. This means that everything you type is sent in plain text. This is a security risk, as anyone can read the messages you send.

However, this is a feature, not a bug. The purpose of this tool is to allow users to append text messages to their network traffic. Encrypting this traffic would be counterproductive.
