5.1. 起動

Armadillo-IoT G3L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。 USBシリアル変換アダプタを接続せずにArmadillo-IoT G3Lに電源を接続した場合、オートブートモードで起動します。

図5.3 起動ログ

5.2. ログイン

起動が完了するとログインプロンプトが表示されます。表5.1「シリアルコンソールログイン時のユーザ名とパスワード」に示すユーザでログインすることができます。

表5.1 シリアルコンソールログイン時のユーザ名とパスワード

ユーザ名	パスワード	権限
root	root	rootユーザ
atmark	atmark	一般ユーザ

初めて機器を接続したときは、必ず以下の手順に従って、初期パスワードを変更してください。

rootでログイン

初期パスワードを変更します。

[armadillo ~]# passwd
Enter new UNIX password: # 新しいパスワードを入力
Retype new UNIX password: # 再入力

atmarkでログイン

初期パスワードを変更します。

[armadillo ~]$ passwd
(current) UNIX password: # 現在のパスワードを入力
Enter new UNIX password: # 新しいパスワードを入力
Retype new UNIX password: # 再入力
[armadillo ~]$


	Armadillo-IoT G3L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ので、初期パスワードのままご利用になるとセキュリティリスクが非常に高まります。セキュリティ強度の高いパスワードに変更し、その後も適切なパスワード運用を行うことを強くお勧めします。

5.3. 時刻の設定

Linuxの時刻には、Linuxカーネルが管理するシステムクロックと、RTCが管理するハードウェアクロックの2種類があります。システムクロックが正しく設定されていない場合、SSL通信が行えないなどの問題が発生します。

システムクロックは、dateコマンドを用いて設定します。dateコマンドの引数には、設定する時刻を[MMDDhhmmYYYY.ss]というフォーマットで指定します。時刻フォーマットの各フィールドの意味を次に示します。

表5.2 時刻フォーマットのフィールド

フィールド	意味
MM	月
DD	日(月内通算)
hh	時
mm	分
YYYY	年(省略可)
ss	秒(省略可)

2015年6月2日12時34分56秒に設定する例を次に示します。

[armadillo ~]# date 
Sat Jan  1 09:00:00 JST 2000
[armadillo ~]# date 060212342015.56 
Tue Jun  2 12:34:56 JST 2015
[armadillo ~]# date 
Tue Jun  2 12:34:57 JST 2015

	現在のシステムクロックを表示します。
	システムクロックを設定します。
	システムクロックが正しく設定されていることを確認します。

図5.4 システムクロックを設定


	Armadillo-IoTが接続しているネットワーク内にタイムサーバーがある場合は、NTP(Network Time Protocol)クライアントを利用してシステムクロックを設定することができます。 `[armadillo ~]#` `ntpdate [NTP SERVER]` 2 Jun 12:34:56 ntpdate[742]: adjust time server x.x.x.x offset 0.004883 sec `[armadillo ~]#` `date` Tue Jun 2 12:34:57 JST 2015

5.4. debianのユーザを管理する

ユーザを作成

例としてguestというユーザを作成します。

[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

パスワードの変更

例としてguestユーザ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

sudoを許可する
例としてguestユーザに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
...
```
ユーザを削除
例としてguestユーザを削除します。
```
[armadillo ~]# userdel guest
```
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

5.5. 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、「Power down」と表示され、ユーザーLED3、ユーザーLED4、ユーザーLED5全てが消灯したことを確認してから電源を切断します。ユーザーLEDの位置については、図7.44「ユーザーLEDの位置」を参照してください

また、SW2を10秒間長押しすることで、終了することも可能です。
