マイデバイス（CCTVデコーダ）が自動的に再起動されるため、LANケーブルを使用してログインできません。 RS232ポートのみがあり、VGAおよびキーボード/USBポート（内蔵PC）はありません。
RS232クロスオーバーケーブルを接続し、Teratermを使用してセットアップモードに入りました。その中にあるすべてのファイルとディレクトリを見ることができます。 rootではファイル/フォルダを編集できません。ただし、Telnetを介して通常のデバイスをリモートで編集できます。私はその理由を知らない。
以下はログです。問題を解決するのに役立ちます。

答え1
ログには、「読み取り専用ファイルシステム」と明示的に複数回表示されます。そのため、ファイルも削除できませんroot。
答え2
ファイルシステムをfsckして再起動できます。 fsckサイレントモードの回復不能エラーのため、ファイルシステムが読み取り専用でマウントされている可能性があります。
以下を行います。
mount
これにより、マウントされたファイルシステムと対応するブロックデバイスが表示されます。次のルートファイルシステムを探します。
/dev/sda1 on / type ext4 (rw,noatime,errors=remount-ro,discard)
あなたの場合、デバイス（例：/ dev / sda1）が異なる場合があります。 /でマウントされたデバイスのファイルシステムをfsckします。
fsck -y /dev/sda1
そして再起動してください。
答え3
ソフトウェアイメージが破損しているか、ハードウェアが予期せず動作しています。私は明白な理由を見ることができません。これはインターネット経由でデバッグできる問題ではないため、直接調査する必要があります。
再起動は、次の原因で発生する可能性があります。
- ハードウェア障害
- ソフトウェアの欠陥（カーネル内にあるか、少なくともカーネルのバグが原因で発生）によって再起動が発生します。
- 欠陥のあるソフトウェア（カーネル内にあるか、少なくともカーネルの欠陥によって引き起こされた）のために監視期限を見逃す可能性があります。
ファイルシステムが読み取り専用でマウントされているため、ファイルを変更できません。考えられる理由は次のとおりです。
- ファイルシステムは読み取り専用でマウントする必要があります。 try
mount -o remount,rw /; - ファイルシステムは起動スクリプトを介して読み取り/書き込みとして再マウントする必要がありますが、起動スクリプトにエラーがあります。
- エラーが検出され、ファイルシステムが読み取り専用にリセットされました。
さらに手がかりを見るには、カーネルログ（の出力dmesg）を確認してください。
デバッグの主な方法は次のとおりです。
- ブートログを既知の良好なデバイスと比較します。
- カーネルログを確認してください。
- デバッガを使用して再起動をプロファイリングします。
問題を調査したくない場合は、既知の良好なファームウェアイメージを再度フラッシュして、もう一度お試しください。
