That's all! At this point you may (optionally) unplug the keyboard, the mouse and the monitor and let the WHP measure the performance of your wireless network!
Security Issues
We suggest that you take additional efforts to safeguard the security of your probes:
- Set the password for the "pi" user and the "root" user of the WiFiMon Hardware Probe.
- Disable auto-login to the WiFiMon Hardware Probe. Open the terminal and type "sudo raspi-config". Then, from the third line "Boot Options", select "B1. Desktop / CLI" and then "B3. Desktop".
- When connecting to your Wi-Fi network, your password will be stored as plaintext to the file "/etc/wpa_supplicant/wpa_supplicant.conf. Use the following commands to hash your ESSID and password:
| Code Block | ||
|---|---|---|
| ||
set +o history
wpa_passphrase YOUR_ESSID YOUR_PASSWORD
set -o history |
A "psk=....." line will be generated. Add this line in /etc/wpa_supplicant/wpa_supplicant.conf under your ESSID and delete the plaintext password.
- Default user "pi" comes with sudo privileges. You can remove them with the following commands from the "root" user:
| Code Block | ||
|---|---|---|
| ||
delgroup pi sudo
rm /etc/sudoers.d/010_pi-nopasswd |
- Convert the privileges of the "/etc/wpa_supplicant/wpa_supplicant.conf" to "600".
- You may configure a firewall to further protect your device.
