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 {{:nas:pasted:20220521-181959.png}} #### 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](https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=4e46ae1f69b5ff1cf09b2e2eee69a7c38a00202d)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→ [[nas:readynas_duo_v2_openwrt_install_log|]] {{:nas:pasted:20220521-221746.png}} とりあえずインストールは出来たようだが。。。 ``` BusyBox v1.35.0 (2022-05-20 19:00:24 UTC) built-in shell

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。 {{:nas:pasted:20220522-144537.png}} 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。 ``` BusyBox v1.35.0 (2022-05-20 19:00:24 UTC) built-in
