第5章 起動と終了

5.1. 起動

Armadillo-IoT G3に電源を接続するときUSBシリアル変換アダプタのスライドスイッチによって起動モードが変わります。 詳しくは「スライドスイッチの設定について」を参照してください。 本節では、保守モードに設定しているときの例を示します。 オートブートモードを選択した場合は、途中でコマンドを入力することなく起動が完了します。

図5.2 起動ログ


[ティップ]

Armadillo-IoTの起動状態をユーザーLEDから確認することができます。このため、Armadillo-IoTにUSBシリアル変換アダプタを接続せずに電源を投入した場合でも、Linuxの起動を確認することができます。

起動状態ユーザーLED1ユーザーLED2ユーザーLED3ユーザーLED4
ブートローダーが保守モード点灯消灯消灯消灯
Linuxの起動中点灯点灯消灯消灯
Linuxが起動完了点灯消灯消灯消灯

ユーザーLEDの位置については、図6.43「ユーザーLEDの位置」を参照してください。

5.2. ログイン

5.2.1. 新しいパスワードの準備

初めてログインしたときは、パスワードの変更を促されます。事前に新しいパスワードを用意してください。

設定するパスワードには大文字のアルファベット、小文字のアルファベット、0から9までの数字、その他(記号・句読点など)を含める事ができます。

表5.1 パスワードに設定可能な値

項目範囲
大文字のアルファベットA~Z
小文字のアルファベットa~z
数字0~9
その他(記号・句読点など)!"#$%&‘()*+,–./:;<=>?@[\]^_`{|}~

表5.1「パスワードに設定可能な値」の中から、4つの項目を全て含めた場合は、6文字以上でなければパスワードの安全性が低いためエラーとなります。 項目が3つの場合は7文字以上。項目が2つの場合は8文字以上。項目が1つの場合は9文字以上のパスワードを設定して下さい。 また、"ABCDEDCBA"など左右対称のパスワードはエラーとなるため使用しないで下さい。

[ティップ]

パスワードを自動生成するpwgenコマンドがあります。作業用 PCにpwgenをインストールして、9桁のパスワードを生成する例を次に示します。

[PC ~]$ sudo apt-get install pwgen
[PC ~]$ pwgen -y 9 1
********* # 9桁の値が生成されます。

5.2.2. 初回ログインと新しいパスワードの設定

初めてログインしたときは、パスワードを変更するようにメッセージが表示されます。以下の手順に従って、パスワードを変更してください。

  1. rootでログイン

    パスワードを変更します。

    You are required to change your password immediately (root enforced)
    Changing password for root.
    (current) UNIX password: root # 初期パスワード"root"を入力
    Enter new UNIX password: # 新しいパスワードを入力
    Retype new UNIX password: # 新しいパスワードを再入力
  2. atmarkでログイン

    パスワードを変更します。

    You are required to change your password immediately (root enforced)
    Changing password for atmark.
    (current) UNIX password: atmark # 初期パスワード"atmark"を入力
    Enter new UNIX password: # 新しいパスワードを入力
    Retype new UNIX password: # 新しいパスワードを再入力

Armadillo-IoT G3はネットワークに接続されることを前提としている機器です。 セキュリティ強度の高いパスワードに変更され、その後も適切にパスワードを運用されることを強くお勧めします。

5.3. debianのユーザーを管理する

  1. ユーザーを作成

    例としてguestというユーザーを作成します。

    [armadillo ~]# adduser guest
    Adding user `[user_name]' ...
    Adding new group `guest' (1001) ...
    Adding new user `guest' (1001) with group `guest' ...
    Creating home directory `/home/guest' ...
    Copying files from `/etc/skel' ...
    Enter new UNIX password: # パスワードを入力
    Retype new UNIX password: # 再入力
    passwd: password updated successfully
    Changing the user information for guest
    Enter the new value, or press ENTER for the default
            Full Name []: # Enterを入力
            Room Number []: # Enterを入力
            Work Phone []: # Enterを入力
            Home Phone []: # Enterを入力
            Other []: # Enterを入力
    Is the information correct? [Y/n] # Enterを入力
  2. パスワードの変更

    例としてguestユーザーのパスワードを変更します。

    [armadillo ~]# passwd guest
    Enter new UNIX password: # 新しいパスワードを入力
    Retype new UNIX password: # 再入力
  3. sudoを許可する

    例としてguestユーザーにsudoを許可します。viの使い方については、「viエディタの使用方法」を参照にしてください。

    [armadillo ~]# visudo
    ...
    # User privilege specification
    root    ALL=(ALL:ALL) ALL
    guest   ALL=(ALL:ALL) ALL # この行を追加します
    ...
  4. ユーザーを削除

    例としてguestユーザーを削除します。

    [armadillo ~]# userdel guest
    [ティップ]

    ホームディレクトリも合わせて消したいときは、"r"オプションをつけます。

    [armadillo ~]# userdel -r guest

5.4. 終了方法

安全に終了させる場合は、次のようにコマンドを実行し、「System halted.」と表示されたのを確認してから電源を切断します。
