EIWD [0]
________________________________________________________________________________

eiwd is iNet Wireless Daemon (iwd) without dbus. iNet Wireless Daemon aims to 
replace @/wpa_supplicant while providing the following benefits:

* Simplification of network management.
* Faster network discovery.
* Fast and reliable roaming.
* Use less system resources.
* Use features offered by the linux kernel.
* Support for enterprise security methods like EAP.
* Support for kernel asymetric key rings and trusted platform modules (TPM).
* Support for multiple clients.


Configuration
________________________________________________________________________________

Ensure that you have the following dependencies installed:

+------------------------------------------------------------------------------+
|                                                                              |
|   $ kiss b eiwd && kiss i eiwd                                               |
|   $ kiss b openresolv && kiss i openresolv                                   |
|                                                                              |
+------------------------------------------------------------------------------+

Create a new daemon configuration file:

+------------------------------------------------------------------------------+
|                                                                              |
|   $ mkdir -p /etc/iwd                                                        |
|   $ touch    /etc/iwd/main.conf                                              |
|                                                                              |
+------------------------------------------------------------------------------+

Using a preferred text editor, add the following lines to the main.conf file 
generated above:

+------------------------------------------------------------------------------+
|                                                                              |
|   [General]                                                                  |
|   EnableNetworkConfiguration=true                                            |
|                                                                              |
|   [Network]                                                                  |
|   RoutePriorityOffset=200                                                    |
|   NameResolvingService=resolvconf                                            |
|                                                                              |
+------------------------------------------------------------------------------+


Adding A Wireless Network
________________________________________________________________________________

eiwd ships with a iwd_passphrase, which can be used for generating iwd network 
files:

+------------------------------------------------------------------------------+
|                                                                              |
|   $ printf PASSWORD | iwd_passphrase BSSID                                   |
|                                                                              |
+------------------------------------------------------------------------------+

Remember to replace BSSID and PASSWORD with your respective network credentials.

Using a preferred text editor, copy the output of the command above to the 
following location: /var/lib/iwd/BSSID.psk


Managed via runsv
________________________________________________________________________________

Busybox's runsv can be used to create a new managed service with the following
command:

+------------------------------------------------------------------------------+
|                                                                              |
|   $ ln -s /etc/sv/eiwd/ /var/service                                         |
|                                                                              |
+------------------------------------------------------------------------------+

To start the new managed service, use the following command:

+------------------------------------------------------------------------------+
|                                                                              |
|   $ sv up eiwd                                                               |
|                                                                              |
+------------------------------------------------------------------------------+


Tips and Tricks
________________________________________________________________________________

* To prevent iwd from continuous scanning while not connected, add the following
  to your main.conf file:

  +----------------------------------------------------------------------------+
  |                                                                            |
  |   [Scan]                                                                   |
  |   DisablePeriodicScan=true                                                 |
  |                                                                            |
  +----------------------------------------------------------------------------+

* To prevent iwd from destroying / recreating wireless interfaces at startup,
  add the following to your main.conf file:

  +----------------------------------------------------------------------------+
  |                                                                            |
  |   [General]                                                                |
  |   UseDefaultInterface=true                                                 |
  |                                                                            |
  +----------------------------------------------------------------------------+

* If idw fails to start, check to make that you have the required kernel 
  options:
  
  CONFIG_CRYPTO_USER_API_HASH
  CONFIG_CRYPTO_USER_API_SKCIPHER
  CONFIG_KEY_DH_OPERATIONS
  CONFIG_CRYPTO_ECB
  CONFIG_CRYPTO_MD5
  CONFIG_CRYPTO_CBC
  CONFIG_CRYPTO_SHA256
  CONFIG_CRYPTO_AES
  CONFIG_CRYPTO_DES
  CONFIG_CRYPTO_CMAC
  CONFIG_CRYPTO_HMAC
  CONFIG_CRYPTO_SHA512
  CONFIG_CRYPTO_ARC4
  CONFIG_CRYPTO_SHA1
