Why? I have several headless Raspberry Pi's doing things and I wanted a simple cross platform way to see what they are up too.
The preferred way is to use pip with pypi.org
pip install hostinfo
For development you can also do:
git clone https://github.com/walchko/hostinfo.git cd hostinfo pip install -r requirements.txt pip install -e .
Now in order to determine your ip and mac address, you need to supply an interface. You can also supply a port to serve up the webpage.
kevin@Logan hostinfo $ bin/hostinfoserver.py -h
usage: hostinfoserver.py [-h] [-e ETHERNET] [-p PORT] [-i IP] [--version]
Launches a server that reports host information via a static web page. Example:
hostinfoserver.py -p 8800 -e en0 -h logan.local
optional arguments:
-h, --help show this help message and exit
-e ETHERNET, --ethernet ETHERNET
ethernet interface, default is eth0
-p PORT, --port PORT port, default is 9000
-i IP, --ip IP host ip address, default is 0.0.0.0
--version show program's version number and exit
Now typically for the --ethernet option, I use:
- en0: on macOS for wifi
- en1: on macOS for wired ethernet
- eth0: on Raspberry Pi 2/3 for wired ethernet
- usb0: on Raspberry Pi Zero for usb RNDIS/Ethernet Gadet
- wlan0: on Raspberry Pi 2/3/Zero for wireless
Now you can create a service that will always start up when the computer boots:
pi@bender hostinfo $ more /etc/systemd/system/hostinfo.service [Service] ExecStart=/usr/local/bin/hostinfoserver.py -p 8080 -e eth0 Restart=always StandardOutput=syslog StandardError=syslog SyslogIdentifier=hostinfo User=pi Group=pi Environment=NODE_ENV=production [Install] WantedBy=multi-user.target
Change the port, ethernet interface, and desire to generate a QR code to your liking. Once you create this file, you need to do:
pi@bender hostinfo $ sudo systemctl enable hostinfo
Created symlink from /etc/systemd/system/multi-user.target.wants/hostinfo.service to /etc/systemd/system/hostinfo.service.
pi@bender hostinfo $ sudo service hostinfo start
pi@bender hostinfo $ sudo service hostinfo status
● hostinfo.service
Loaded: loaded (/etc/systemd/system/hostinfo.service; enabled)
Active: active (running) since Sun 2017-01-22 13:14:26 MST; 7s ago
Main PID: 28533 (infoserver.py)

Jan 22 13:14:26 bender systemd[1]: Started hostinfo.service.
Now that the server is up and running, just launch a browser and connect
to computer:port. For example, bender.local:8080 because that is
what I set it too above.
