ReadyNAS Duo v2 の Open-WRT化

概要

Open-WRT は 主にブロードバンドルーター向けの Linuxディストリビューション。
コミュニティの情報によればNETGEAR の NAS box ReadyNAS Duo v2 にもインストールできる。
ReadyNAS Duo v2は、製造から10年近く経過しており、すでに公式サポートも終了。
中のOSも相当古くなっているので、Open-WRTに入れ替えることで延命を図る。

イメージの入手

https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=kirkwood%2Fgeneric&id=netgear_readynas-duo-v2

上のリンクからKERNELとSYSUPGRADEをダウンロードする。

KERNEL：openwrt-kirkwood-netgear_readynas-duo-v2-initramfs-uImage
SYSUPGRADE：openwrt-kirkwood-netgear_readynas-duo-v2-squashfs-sysupgrade.bin

私のあやふやな理解

KERNEL　必要最小限の内容だけのイメージ
SYSUPGRADE　KERNELで起動した上で、sysupgrade して使うフル版のイメージ

準備

  • ReadyNASとPCをシリアル接続できるようにしておく
  • FAT32でフォーマットしたUSBメモリに KERNELイメージを保存しておく

手順

ここにざっくり書かれている

Installation by USB + serial:
- Copy initramfs image to fat32 usb drive
- Connect pendrive to USB 2.0 front socket
- Connect serial console
- Stop booting in u-boot
- Do: 

usb reset
setenv bootargs 'console=ttyS0,115200n8 earlyprintk'
setenv bootcmd 'nand read.e 0x1200000 0x200000 0x600000;bootm 0x1200000'
saveenv
fatload usb 0:1 0x1200000 openwrt-kirkwood-netgear_readynas-duo-v2-initramfs-uImage
bootm 0x1200000

- copy sysupgrade image via ssh.
- run sysupgrade

作業ログ

とりあえずインストール

手順の通りやってみる。

コンソールログ→ readynas_duo_v2_openwrt_install_log

とりあえずインストールは出来たようだが。。。

opkgコマンドがエラー
WebUIのLuciがインストールできない。
これではインストールできたはよいが、まるで何もできないぞ・・・

ネットワークに問題ある？

ping打ってみる。

opwnwrt.org　NG
google.com　NG
yahoo.co.jp　OK

IPv6のアドレスがダメってことか・・・:-?

あれ、でも他のPCからping打つと IPv4だよ・・・:?:
Windows10のWSL2のUbuntuからpingを打ったら

なんで OpenWrtなRedyNASは IPv6 になってるんだろ:-/

Luciのインストール

opkg が使えない

方針

とりあえず Open-Wrt はインストールされ、ssh接続できるようにはなった。

Webの設定画面 luci をインストールしようとしたが opkg コマンドがエラーになる。
これでは、何もパッケージがインストールできない。

はて、、、

どうやら ipv6 で接続しようとして、接続できないでいるようだ。
localhost は ipv6 でもpingが通るけど、外部のサイトは ipv6 だと pingが通らない。

接続できない原因が、うちのインターネット環境（フレッツ、OCN）にあるのか、ブロードバンドルーター（結構古いNEC ATerm）にあるのか、その両方のせいなのか、設定が悪いだけなのか、ちょっと分からない。

《追記》
我が家のインターネット環境ではIPv6接続ができていない（面倒くさくて設定していない）ことが判明した。

ipv4 なら問題なく接続できているので、安直に考えて ipv6 を無効にして ipv4で接続するようにしたい。
