BBルータ解剖

NTTE/NTTW Web Caster V100

個人的な雑感
NTT東日本/NTT西日本のルータですので、電話に関する機能が豊富のようです。 IP電話に対応し、ナンバーディスプレイやキャッチホンなども使えます。ただ、個人的な感想を言うと、デザインが少々古臭い感じがします。スループットが 30Mbps の製品なので、ADSL向けだと思うのですが、電話回線を接続すると、スプリッタで分けた信号の両方を接続することになり、少し変な感じがするのは、私だけでしょうか。2004.6.25

CPU と OS
ファームウェアから、 CPU は MIPS 系の CPU だと思われます。同じく、 OS は Linux version 2.4.2_hhl20 (kitagawa@ivgw055) (gcc version 2.95.3 20010315 (release/MontaVista)) #3 2004年 4月 7日水曜日 13:42:34 JST のようです。 MontaVista ベースみたいです。この kitagawa さんというのは、開発チームの人の名前のようで、バイナリの中に /jordan/matrix/team-kita/V100_V22/rgw/OS/ という記述が散見されます。

アップデートファームの取り出し
確認ファーム Version : 2.2.0
NTT東日本から (もしくは西日本のページから) Ver 2.2.0 のファームウェアファイルをダウンロードします。ダウンロードしたファイルは tar + gzip 形式のファイルですので、 tar や zcat + tar などで、解凍します。解凍すると、４つのファイルが得られます。 CALLTBL.DEF FILEINFO.TXT KERNEL.BIN ROOTIMG.BIN このうち、 CALLTBL.DEF と FILEINFO.TXT は制御／情報用のサイズの小さなファイルです。 KERNEL.BIN ファイルはその名の通り、 kernel を含んでいます。以下のコマンドで gzip 形式の部分だけを取り出します。 dd if=KERNEL.BIN of=image bs=1 skip=11992 count=575223 この count 値は間違っているかもしれません。この取り出したファイルは gzip 形式で圧縮されているのですが、 count 値が正しくないかもしれないので、解凍ツールによってはエラーが発生するかもしれません。このファイルを解凍すると zImage ファイルが取り出すことができます。 ROOTIMG.BIN ファイルは、 jffs2 イメージで出来ていますので、中身を取り出すには、 mtd のツールなどを使わないと取り出せません。以下は、 ROOTIMG.BIN ファイルの中身です。 drwxrwxr-x 1 0 0 0 Apr 7 12:55 /dev/ drwxrwxr-x 1 0 0 0 Apr 7 12:55 /dev/pts/ crw-r--r-- 1 0 0 202, 1 Mar 14 2003 /dev/vodspa1 crw-r--r-- 1 0 0 201, 7

アップデートファームの取り出し

確認ファーム Version : 2.2.0

NTT東日本から (もしくは西日本のページから) Ver 2.2.0 のファームウェアファイルをダウンロードします。ダウンロードしたファイルは tar + gzip 形式のファイルですので、 tar や zcat + tar などで、解凍します。解凍すると、４つのファイルが得られます。

CALLTBL.DEF
FILEINFO.TXT
KERNEL.BIN
ROOTIMG.BIN

このうち、 CALLTBL.DEF と FILEINFO.TXT は制御／情報用のサイズの小さなファイルです。 KERNEL.BIN ファイルはその名の通り、 kernel を含んでいます。以下のコマンドで gzip 形式の部分だけを取り出します。

dd if=KERNEL.BIN of=image bs=1 skip=11992 count=575223

この count 値は間違っているかもしれません。この取り出したファイルは gzip 形式で圧縮されているのですが、 count 値が正しくないかもしれないので、解凍ツールによってはエラーが発生するかもしれません。このファイルを解凍すると zImage ファイルが取り出すことができます。

ROOTIMG.BIN ファイルは、 jffs2 イメージで出来ていますので、中身を取り出すには、 mtd のツールなどを使わないと取り出せません。
以下は、 ROOTIMG.BIN ファイルの中身です。
