Network Configuration

iwd

• Required for DHCP: systemd-resolved or dhcpcd (recommended)

Connection

• Start the DHCPCD daemon from root

  sudo systemctl enable dhcpcd.service
  sudo systemctl start dhcpcd.service
  # sudo dhcpcd
  

• Start the IWD service

  sudo systemctl enable iwd.service
  sudo systemctl start iwd.service
  

802.1x networks

• You must create a config file in /var/lib/iwd/ that ends with “ssid.8021x”
• If the file has special character (dot, comman, at sign, etc.), the config file name must be hex encoded

For example, wpa.mcgill.ca

Encoding:

echo -n "wpa.mcgill.ca" | od -A n -t x1 | sed 's/ *//g'
# should return 7770612e6d6367696c6c2e6361

Create a config file

sudo cd /var/lib/iwd/ sudo touch =7770612e6d6367696c6c2e6361.8021x

Edit the file

- To configurate the network using EAP-PEAP and MsCHAPv2: (for example, as a McGill Student)

[Security] EAP-Method=PEAP EAP-Identity=anonymous EAP-PEAP-Phase2-Method=MSCHAPV2 EAP-PEAP-Phase2-Identity=your.email@mail.mcgill.ca EAP-PEAP-Phase2-Password=yourpassword

[Settings] AutoConnect=true ```
