[plamo:28292] Re: Note PC のネットワーク設定

[KATOH Yasufumi]

加藤泰文です．

もうちとちゃんとテストしてみてます．が，長くなったので，最初に質問を．

やりたいことは
  - 常に同じ名前が同じデバイスに割りあたる
  - 有線がつながっていたら，有線 LAN は有効に．
  - 無線は手動でオンにするので OK．
ってな感じで，後ふたつは普通に Planet を使うときの例として載っているも
のかと．

  『どう設定すれば，このようになるでしょう?』 (^_^;)

--------
以下に状況を．
  http://tara.harp.gr.jp/~kato/plamo/index.php?X30
にもう少し詳しい情報を (ただし有用な情報かどうかは謎)．

PC のスペックについては，
  http://wuw.stusta.mhn.de/~u002149a/thinkpad/
が参考になるかな．とりあえず
  有線 LAN: Intel EtherExpressPro/100
  無線 LAN: Prism 2.5 Wavelan
の模様．

とりあえず，先の udev の設定はなしで．modprobe.conf にはそれらしい設定
をしてやってます (効いてないような)．有線 LAN はつないだ状態でテストし
てます．Planet は，eth0, eth1 共に，リンクしていれば有効にする設定 (どっ
ちに有線が割りあたるかわからないので)．

# alias eth0 e100
# alias eth1 orinoco_pci
# と modules.conf に書いて，generate-modprobe.conf を実行．
# 全部コレでやったかは覚えてない部分もありますが，名前が設定と逆になっ
# ていたのは覚えてます．

ネットワークは Planet を使用する，としています．

結論から言うと，planet でちゃんとネットワークが有効になるところまでは
なったりならなかったりなんですが，手動で必要な操作をやれば，使えるよう
になる，という気がしています．ただし，起動するたびに，状況が違うので，
絶対 OK なのかというとわかりません．


------------

以下に状況を．起動するたびに状況は違います．以下，パターンごとに

(1) 無線 LAN のみ OK な状況．
# これは modprobe.conf 書いてなかったかも?

e100 も orinoco_pci も eth0 って出力があるけど，udevinfo で見ると，違
う．

udevinfo

bash-3.00# udevinfo -a -p /sys/class/net/eth0
   : (snip)
 looking at device '/class/net/eth0':
   KERNEL=="eth0"
   SUBSYSTEM=="net"
   : (snip)

bash-3.00# udevinfo -a -p /sys/class/net/eth1
   : (snip)

   DRIVER=="e100"
   : (snip)

で，無事無線 LAN 経由でアドレスが割り当たり，通信出来てます．

(2) 有線のみ OK

e100 は eth0 に，orinoco_pci は eth1 に，planet では eth0 が有効になり，
アドレスも割り当たり，通信可能．

もしかしたら，eth1 も自分で iwconfig で設定して，dhclient 実行したらい
けていたかも? (未調査)

udevinfo は dmesg と矛盾なく，情報が表示されていました．

(3) 有線，無線とも OK

有線，無線とも Ok のパターン．

(4) 両方ダメ

両方ダメなパターン．ただし，後で手動で設定したら，通信可能だったので，
デバイスの認識には問題がないもよう．
