---

Networkを Swハブのように動作させるため brctlを組み込むのに sourceから kernelを再構築する必要がありました。

作業的には、以下の方法で進めます。

(1) kernelオプションの確認
(2) ソースの展開
(3) コンパイル

うまくいけば、時間がかかるだけで手順的には難しくありません。

kernelオプション確認

今回は brctlというネットワークをブリッジ接続する為に kernelを再コンパイルしたのですが、
以下のオプションを確認(変更)する必要がありました。

802.1d Ethernet Bridging
Network packet filtering debugging

それぞれを、Enable,Disableであることを以下の方法で確認できます。

/usr/src/linux/make menuconfigを実行
以下のメニューが表示されるので、Networking optionsにカーソル合わせてエンター

Network packet filtering debuggingが有効のままで brctlを機能させると、以下のようなメッセージが
/var/log/messagesへ鬼のように書き込まれます。
messagesって、殆ど何も書き込まれないログファイルなのですが、数十分で 10Mbyteぐらいのログが出来上がってびっくりしました。

/var/log/messages

kernel sourceからの make

アットマーク・アイティのサイトを参考にさせていただきました。

以下の所から kernel sourceを rpmします。

rpm -ivh http://www.dnsbalance.ring.gr.jp/archives/linux/Vine/Vine-2.6/updates/RPMS/i386/kernel-source-2.4.22-0vl2.19.i386.rpm

/usr/src/linux下に展開されるようなので、以下のコマンドを実行

cd /usr/src/linux make menuconfig

詳しくは brctlのページを参照

make dep make clean make bzImage make modules make modules_install

これから先は、エイヤ！でやってしまったので記録が残っていません。
次やるときに更新しようと思います。

一応メモ

以下のファイルが出来上がります。

/usr/src/linux/arch/i386/boot/bzImage /usr/src/linux/System.map

これを /bootディレクトリーへコピー
自分の好きな名前でよいです。

cp /usr/src/linux/arch/i386/boot/bzImage /boot/bzImage-200506 cp /usr/src/linux/System.map /boot/System.map-200506
