BBルータ解剖
　
LINKSYS RV082-JP
個人的な雑感

VPN を売りにしたルータで、 CPU は IXP425 533MHz とあります。 このページを表示している web サーバ兼メールサーバよりも、ずっと高性能です。 VPN をするからだと思いますが、すごいな、と思います。デザインは、 SOHO 向けとしてはすっきりした感じで、シンプルで良いと思います。 LAN の口が前面にありますが、個人的には裏面にあった方が便利だと思います。 2006.1.14

CPU と OS

CPU は IXP425-533MHz を搭載しているようです。OS はファームウェアから、

Linux version 2.4.19openrg-rmk6-ds1 #2 Tue Jan 25 11:35:47 CST 2005

もしくは

Linux version 2.4.21openrg-rmk1 #1 Thu Oct 21 15:31:20 CST 2004

だと思われます。


アップデートファームの取り出し
確認ファーム Version : V2.0.0.21JP

LINKSYS のページからファームウェアをダウンロードしてきます。 ダウンロードしてきたファイル rv082-jp_20021_20050204_web.EXE を解凍します。 解凍すると

rv082-jp_release_note.txt
rv082-jp_upgrade_guide.pdf
upgrade.exe

の３つのファイルが取り出せます。 この中の upgrade.exe の中に、ファームウェアの中身が格納されています。
この実行ファイル、中を見ると、 web サーバと通信しているようなところがあって、 面白いです。ちょっとだけ通信内容を見てみたのですが、 telnet を開こうと したりしています。そのときに、良いのか悪いのか http の Basic 認証の パスワードが見えてしまっているので、バックドアじゃなきゃ良いのだけど、 とちょっと心配です。
予想では RV082_2.0.0.21-jp_050125.rmt というファイルを送信しているの ですが、どこが区切りかわからなかったので、バラバラに取り出します。

[toyota@kashyyyk]% 1f8b upgrade.exe

upgrade.exe file size:6565888
upgrade.exe 000cadc9( 830921) 2e 0a 00-1f 8b 08 00 a4 be f5 41
upgrade.exe 0054dd84( 5561732) 2e 0a 00-1f 8b 08 00 72 66 77 41
upgrade.exe 005bb29c( 6009500) 00 20 00-1f 8b 08 08 c2 65 77 41 rd.img

とのことですので、３つのファイルは取り出せそうです。さっそくやってみます。

[toyota@kashyyyk]% dd if=upgrade.exe of=image0.gz bs=1 skip=830921 count=4679997
[toyota@kashyyyk]% dd if=upgrade.exe of=image1.gz bs=1 skip=5561732 count=447293
[toyota@kashyyyk]% dd if=upgrade.exe of=rd.img.gz bs=1 skip=6009500 count=394386

最初のファイル image0.gz を解凍すると image0 というファイルになると 思います。このファイルの先頭は kernel のようです。バージョンは 以下のものです。

Linux version 2.4.19openrg-rmk6-ds1 #2 Tue Jan 25 11:35:47 CST 2005

次に rd.img というファイルが続いていますので、取り出してみます。

[toyota@kashyyyk]% dd if=image0 of=rd.img.gz bs=1 skip=1425408 count=21433

解凍して、 mount してみます。

[toyota@kashyyyk]% gunzip rd.img.gz
[root@kashyyyk]% mount -o loop rd.img /mnt

以下に rd.img の中身の tree 結果を付けます。

最後に cramfs のイメージがあります。これを取り出します。

[toyota@kashyyyk]% dd if=image0 of=image3 bs=1 skip=1449984

さらに、このファイルをマウントしてみます。

[root@kashyyyk]% mount -o loop image3 /mnt

以下に image3 の cramfs の tree 結果を付けます。

sysinfo123.htm, sysinfo124.htm あたりは隠しファイルじゃないかな、と思います。 その他のファイルはじっくり見ていないのでわかりませんが、面白いファイルが あるかもしれません。

２番目のファイルを解凍してできたファイル image1 は kernel のようです。 何故 kernel が２つあるのか不思議です。詳細なバージョンは以下のものです。

Linux version 2.4.21openrg-rmk1 #1 Thu Oct 21 15:31:20 CST 2004

最後の rd.image.gz ファイルは解凍すると ext2 形式のファイルシステムの イメージで、ちょうど 800000バイトのファイルです。解凍して、mount を してみます。

[toyota@kashyyyk]% gunzip rd.img.gz
[root@kashyyyk]% mount -o loop rd.img /mnt

以下に rd.img の中身の tree 結果を付けます。
