wireless setup (wpa) の メモ

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

wlan0 Link encap:Ethernet HWaddr 00:1F:E1:5C:59:0E inet addr:192.168.0.10 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1771 errors:0 dropped:0 overruns:0 frame:0 TX packets:1924 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:613480 (599.1 Kb) TX bytes:380595 (371.6 Kb)
