환경 : CentOS release 5.6 (Final)
무선랜 Adaptor : Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
인증 방법 : WPAPSK
암호화방법 : AES
1. wpa_supplicant 설치 ( 없으면 )
# yum install wpa_supplicant
2. wpa_supllicant 설정
가. 암호 설정
#wpa_passphrase [SID] [PASSWORD] > /etc/wpa_supplicant/wpa_supplicant.conf
나. 추가 항목 설치
network={
ssid=SID
psk=암호화된 PASSWORD
key_mgmt=WPA-PSK
proto=WPA WPA2
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40
}
다. 설정 확인
# wpa_supplicant -iwlan0 -Dwext -c /etc/wpa_supplicant/wpa_supplicant.conf
(wext) Device wlan0 kernel driver name: ath5k.
Device wlan0 kernel driver name: ath5k.
ioctl[SIOCSIWAUTH]: Operation not supported <- 무시. 정상 동작함.

3. IP 설정
가. DHCP
#dhclient
나. 고정 IP
#ifconfig wlan0 [IP] netmask [SUBNET MASK]
4. 자동 설정
가. wpa_supplicant 확인
INTERFACES="-i wlan0"
DRIVERS="-D wext"
나. wpa_supplicant 자동 실행 정지
# chkconfig wpa_supplicant off
# chkconfig --list |grep wpa_supplicant
wpa_supplicant 0:off 1:off 2:off 3:off 4:off 5:off 6:off
다. 무선 랜 자동 실행 및 암호 삭제
#vi /etc/sysconfig/network-scripts/ifcfg-wlan0
ONBOOT=no
# rm /etc/sysconfig/network-scripts/keys-wlan0
라. 자동 실행 rc 에 추가
#vi /etc/rc.local
/sbin/service wpa_supplicant start
/sbin/ifup wlan0
/sbin/dhclient <- DHCP 사용시
