Logs which devices are in your local network and draws graphs

Screenshot:

1. Clone this repository and checkout the precompiled branch

   git clone https://github.com/phiresky/nmap-log-parse
   cd nmap-log-parse
   git checkout gh-pages

2. Add this line to your root crontab on your raspberry pi (or other device that is always on):

   */10 * * * * nmap -sn '192.168.178.*' -oX - >> /var/www/nmap-logs/$(date -I).xml

   You can edit the root crontab by running something like sudo EDITOR=nano crontab -e

   Replace '192.168.178.*' with your network range and /var/www/nmap-logs/ with the target location.

   This takes about ~10MB of storage per month.

   The above command must be put into the root crontab! Otherwise, nmap can't read mac-addresses and the output will be wrong.

3. create a config.json file in the same folder as the built index.html is in (dist), overriding any of the values in the default config.

   for example:

   config.json

   {
   	"logFilesPath": "/nmap/logs/",
   	"staticLogFiles": ["logs/oldlogs"],
   	"deviceNames": {
   		"AB:CD:EF:01:23": "John's PC"
   	}
   }

   Use staticLogFiles only if you have an undated log file from an older version.

   The logFilesPath is either relative to the root dirctory of the server (if starting with /) or the built index.html file (otherwise)

4. Wait more than an hour. Make sure the first log file (in the form 2019-06-29.xml) exists and contains XML documents.

5. Open index.html in a browser. Open it from a server (like a minimal python3 -m http.server) instead of from the filesystem because of Cross-Domain security.

Made with React, the Dexie.js database and Highcharts.

Get the dependencies using yarn install, then run yarn build to build the JS into the /dist directory. For development, run yarn dev to start the dev server.

This project is written in TypeScript, which is basically JavaScript (ES6), but strongly typed. I can recommend Visual Studio Code (on linux) for IntelliSense and Refactoring support.

If you have ideas to make this better please open an issue, or even better, send a pull request.
