Add hidden SSID support about device-init

[Govinda-Fichtner]

It looks like the configuration is still missing one line:

auto wlan0
iface wlan0 inet dhcp
  wpa-ssid MyNetwork
  wpa-ap-scan 1
  wpa-scan-ssid 1
  wpa-psk generated_psk

At least according to:

http://unix.stackexchange.com/questions/48431/connect-to-hidden-wifi-ap-with-wpa-supplicant

As supporting a hidden access point needs to parameters I wonder if 'hidden-accesspoint' setting with 'true|false| would be the best way of implementing it.

As a default it would be 'false'. If set to true it would add those two additional lines to the configuration.

@StefanScherer WDYT?

What about adding the wpa-ap-scan like this? Is wpa-psk = password in yml?

wifi:
  interfaces:
    wlan0:
      ssid: "MyNetwork"
      scan-ssid: 1
      ap-scan: 1
      password: "secret_password"

After some discussion Stefan and I thought it might be best if we rename the existing config settings for Wifi to the corresponding wpa config settings and just pass through all settings starting with "wpa-":

wifi:
  interfaces:
    wlan0:
      wpa-ap-scan: 1
      wpa-scan-ssid: 1
      wpa-ssid: "MyNetwork"
      wpa-proto: "RSN"
      wpa-pairwise: "CCMP"
      wpa-key-mgmt "WPA-PSK"
      wpa-psk "secret_password"

This way it is easy to lookup all the wpa-supplicant options and use them as needed.

That seems nice to me. Will it be implemented in the next release?

Hi there, have these changes (wpa-psk pass through) been implemented already? Maybe I should test it before I ask ... ;)

Closing as we switch over to cloud-init/cloud-config's user-data file.
There should be a scriptable way to do this in a user-data script
