wireless setup (wpa) の メモ

Memo Arch Linux

前置き

WPAだと，iwconfigだけでは接続できなくて，wpa_suppliantが必要だった．
手間取ったので，メモを残しておく．

参考

WPA supplicant - ArchWiki

やったことなど．

無線LANの機械には
WPA-PSK(AES)
と書いてあった．

設定ファイルの作成．

# mv /etc/wpa_supplicant.conf /etc/wpa_supplicant.conf.original
# wpa_passphrase <essid> <password> > /etc/wpa_supplicant.conf

/etc/wpa_supplicant.conf に以下を追加．

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=network

無線を有効にする．

# ifconfig wlan0 up
# iwconfig wlan0 essid <ssid>
# wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf 
# dhcpd wlan0
dhcpcd: version 5.1.4 starting
dhcpcd: wlan0: broadcasting for a lease
dhcpcd: wlan0: offered 192.168.0.10 from 192.168.0.1
dhcpcd: wlan0: acknowledged 192.168.0.10 from 192.168.0.1
dhcpcd: wlan0: checking for 192.168.0.10
dhcpcd: wlan0: leased 192.168.0.10 for 86400 seconds
dhcpcd: forking to background

確認．

# ifconfig wlan0
