5. Adım: Cihaz bir hizmete bağlanır
Bir politika nedeniyle, Shill, cihazın "service 0"a (hizmet 0) otomatik olarak bağlanacağını belirtir. Kullanıcı farklı bir kablosuz ağa bağlanmayı tercih ederse, farklı bir hizmet numarası seçilebilir.
Günlükler
- wpa_supplicant ağların önceliklerini belirler. Bir ağ; güvenlik politikası, sinyal gücü gibi ölçütler temelinde diğerlerine göre daha fazla tercih ediliyorsa, bu ağın öncelik değerini artırabilirsiniz. Chrome için, öncelik grubu değeri değişmez. Bu değer, günlüklerde her zaman "priority group 0" (öncelik grubu 0) olarak gösterilir.

9. Adım: Cihaz ve erişim noktası, grup anahtarı anlaşma işlemi gerçekleştirir
Cihazın, şifrelenmiş çoklu yayın almasına ve erişim noktasından mesaj yayınlamasına izin vermek için wpa_supplicant, cihazla erişim noktası arasında grup anahtarı anlaşma işlemi gerçekleştirir. AP, cihaza grup geçici anahtarı (GTK) gönderir ve cihaz da bunu onaylar.

10. Adım: Cihaz DHCP'yi yapılandırır
Ardından, DHCP yapılandırması gerçekleştirilir. Cihaz bir ağa ilk kez bağlandığında, alt ağına bir DHCP DISCOVER mesajı yayınlar. DHCP sunucusu, cihaza bir IP adresi verir. Cihaz, IP adresini resmi olarak DHCP REQUEST mesajıyla ister. Bu istek DHCP sunucusu tarafından DHCP ACKNOWLEDGE mesajıyla onaylanır. Ardından cihaz, ayarlarını bu IP bilgilerini kullanacak şekilde günceller.
Günlükler
- WiFi bağlantısı tamamlanır.
CTRL-EVENT-CONNECTEDifadesini içeren satıra bakın. - Shill hizmetinin, IP bilgilerini DHCP sunucusundan alması gerekir. Shill kablosuz bağlantı durumu, "completed" (tamamlandı) olarak değişir. Shill hizmet durumu "configuring" (yapılandırılıyor) olarak değişir.
- DHCP hizmeti, 14295 işlem numarası (pid) kullanılarak başlatılır.
- Günlüklerde, 0x63526f44 DHCP işlem no'su (xid) gösterilir.
- DHCP sunucusu, cihazın IP adresini sağlamanın yanı sıra, ağ geçidi IP adresi ve Alan Adı Sunucusu (DNS) ayrıntıları gibi ek bilgiler de sağlar. Bu ek bilgileri
Processing Keys(İşlem Anahtarları) ifadesini içeren satırlarda görebilirsiniz. - Cihaz IP adresini aldıktan sonra, bu adresi IP yönlendirme tablosundaki varsayılan ağ geçidine kaydeder. Ancak ilk olarak, ağ geçidinin MAC adresini, Adres Çözümleme Protokolü (ARP) kullanarak IP adresinden çözmesi gerekir.
