08 Aero Network and System Administration

SysAdmin: Ubuntu Installation

Ubuntu is not supported by Intel on Aero. We are providing a Yocto based image.

But you can install it yourself. You can expect an easy installation (boot, wifi, video, storage, USB OTG work).

Some features, like the USB3 or RealSense connector, are not currently working with the default Ubuntu installation.

Networking: Access Point Wifi

By default, Intel's Yocto for Aero is broadcasting a WiFi access point called 'Aero-' and Wi-Fi password is 1234567890.

The IP of Aero is 192.168.8.1 (newer releases) or 192.168.1.1 (older releases). Login is root, no password.

Launch a terminal and connect to aero via ssh.

ssh [email protected]
# or ssh [email protected] for older releases

On Linux it's possible to use the link-local name rather than fixed IP. Refer to the documentaiton of your distro on how to enable it; it's enabled by default on Fedora and Archlinux's documentation work on several distros:

ssh [email protected]

Networking: Internet Access

In order to have internet access on Aero board it's possible to switch it to client mode so it connects to your Access Point instead of being an Access Point itself.

To change the wifi configuration, connect locally to Aero (with keybaord and screen, or direct USB cable).

• To switch to Wifi client mode use the command:

  /etc/init.d/autostart-supplicant.sh start

• Open the command line Wifi tool:

  wpa_cli –iwlan0

• Scan Wifi networks, show results, add a network config, select it, set the password, enable and select it, save:

  scan
  scan_res
  add_net
  # will return a number, ex: 1
  set_net 1 ssid "my_ssid"
  # note : if your network has spaces, use the mac adress instead
  set_net 1 bssid "xx:xx:xx:xx:xx:xx"
  set_net 1 psk "my_password"
  enable_net 1
  select_net 1
  save_config
  # it will write the config in /etc/wpa_supplicant.conf
  quit
  ifconfig wlan0

  The result of ifconfig will give your IP address. Or you can ask your router-dhcp server what IP was assignated to Intel Aero.

• With this method, your PC and Aero both have internet access and you can ssh to Aero. The SSID and password are saved in a file between reboots. But the board will reboot with the AP mode by default. To set the client mode as default after future reboots, type:

  update-rc.d -f autostart-hostapd.sh remove
  update-rc.d -f autostart-supplicant.sh defaults
  reboot

• If you want to switch back to AP mode by default at boot type:

  update-rc.d -f autostart-supplicant.sh remove
  update-rc.d -f autostart-hostapd.sh defaults
  reboot
