13.1. Kernel configuration

커널 설정은 버전에 따라 다른것 같다. Kernel 2.6.20을 사용하여 테스트 하였다.

# rc-update add ipw3945d default

13.3. Configuration

인증 방식에 따라 설정방법이 틀린다.

(1) 일반적으로 공개된 무선랜 환경일 경우

# vi /etc/conf.d/net

config_eth0=( "dhcp" )   ### Wired LAN

modules=( "wpa_supplicant" )   ### Wireless LAN

wpa_supplicant_eth1="-Dwext"

config_eth1=( "dhcp" )

dhcp_eth1="nontp nonis"

depend_eth1() {

        need ipw3945d

}

# vi /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=wheel

update_config=0

fast_reauth=1

network={

  ssid="MySSID"

  priority=5

}

(2) 암호가 설정된 무선랜 환경일 경우

# vi /etc/conf.d/net

config_eth0=( "dhcp" )   ### Wired LAN

modules=( "iwconfig" )   ### Wireless LAN

wpa_supplicant_eth1="-Dwext"

config_eth1=( "dhcp" )

dhcp_eth1="nontp nonis"

depend_eth1() {

        need ipw3945d

}

# vi /etc/conf.d/wireless

key_MySSID="s:MyPassword enc open"

preferred_aps=( "MySSID" )

# vi /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=wheel

eapol_version=1

update_config=0

ap_scan=1

network={

  ssid="MySSID"

  key_mgmt=NONE

  auth_alg=SHARED

  priority=5

}

(3) EAP 인증방식을 지원하는 무선랜 환경일 경우

# vi /etc/conf.d/net

config_eth0=( "dhcp" )   ### Wired LAN

modules=( "wpa_supplicant" )   ### Wireless LAN

wpa_supplicant_eth1="-Dwext"

config_eth1=( "dhcp" )

dhcp_eth1="nontp nonis"

depend_eth1() {

        need ipw3945d

}

# vi /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=wheel

eapol_version=1

update_config=0

ap_scan=1

fast_reauth=1

network={

  ssid="KNET"

  key_mgmt=WPA_EAP

  eap=TTLS

  identity="MyID"

  password="MyPW"

  pairwise=TKIP

  group=TKIP

  auth_alg=LEAP

  priority=5

}

13.4. Init script

# ln -s /etc/init.d/net.lo /etc/init.d/net.eth1

# rc-update add net.eth1 default

13.5. Rebooting

# reboot
