M1210 CentOS 2 無線LANデバイスの認識

日付:
ubuntuからCentOSになっても便所サーバが目的なことにはかわらないこのマシン。
さすがにデフォルトで無線LANが接続できていたりはしないのでいろいろやる必要がありそう。

とりあえずハードウェアを認識しているのかどうか確認するために↓

# lspci | grep etwork
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

どうやら認識している様子。インテルの3945ABGというやつらしい。
↓ココを参考にさせてもらって設定。

CentOS5.1で無線LANを使う

まずyumにATrpmsリポジトリを追加

#vi /etc/yum.repos.d/atrpms.repo
[atrpms]
name=Redhat Enterprise Linux $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/stable
enabled=0
gpgcheck=1
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms

普段はこのリポジトリは使わないようにしておくので、enabled=0にておく。
ATrpmsを使う時はyumのオプションで--enablerepo=atrpmsをつける。
さっそくyum実行。

# yum --enablerepo=atrpms  list  ipw3945*

どれが正しいのか分からないのでなんとなくipw3945.i386にしてみる。

キーをインポートするよといっているのでy yとやる。

入りました。次はモジュール組み込み。
eth0は有線が使っているのでeth1にする。

# echo "alias eth1 ipw3945" >> /etc/modprobe.conf

ipw3945dの自動起動設定して再起動

# echo "/sbin/ipw3945d --quiet > /dev/null 2>&1" >> /etc/rc.loca
#reboot

起動が終わったら確認してみる。

すでにはいっているといわれた。エラーになったログをみてみると、確かに最初にインストールしているっぽい。
ということはplusっていらないのかも。とりあえずコレで動くかもしれないので再起動してみる。
起動し終わったのでログをみてみる。

追加したものを削除するために編集。

# vi modprobe.conf

最終行の↓を削除。

alias eth1 ipw3945

こっちも同様に

# vi /etc/rc.local

最終行削除

/sbin/ipw3945d --quiet > /dev/null 2>&1

そして再起動

# reboot

よくみるとこんなものが↓。名前からしてどう見ても無線LAN用のものにしか思えない。

-rw-r--r--  1 root root   131 10月  9 05:25 ifcfg-wlan0

中をみてみる。

# more ifcfg-wlan0

# Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection
DEVICE=wlan0
BOOTPROTO=dhcp
ONBOOT=no
HWADDR=00:19:d2:90:53:96

正しそうなことが書いてある。ファイルの作成日時をみてもeth0と7分しか変わらない。
自分でなにかドライバとかをいれたりした時に生成されたのであれば日付も違うはずなので最初から認識していたのでは？
と思ってモジュール設定を見てみるとちゃんと3行目にいました。

# more /etc/modprobe.conf
alias eth0 b44
alias scsi_hostadapter ata_piix
alias wlan0 iwl3945
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel

なのでモジュール一覧をみるとちゃんといました。
