2. USB Hub (with power)
充足電力 Power Supply - 最好使用帶電 USB 2.0 Hub
建議使用呢款 USB 3.0 Hub，完全解決電力不足 reboot 的情況。
3. 支援  USB 3G 手指，例如華為 E180
4. USB Wifi 手指，例如 TP-Link WN823N

軟件要求

1. SSH - Client Putty
2. File Manager - WinSCP
3. VOIP - Soft client - 如 Zoiper
4. Windows VNC Clients - Tight VNC Viewer  &  Ultra VNC Viewer

ckleea

下載、準備、啟動

下載及基本安裝程序：

1. 下載 最新版本
2. 用 Winzip 或 7-zip 打開和放出 RASPASTDON-XXXXXXXX.img
3. 使用 Win32DiskImager  打開 RASPASTDON-XXXXXXXX.img， 寫入一張有 8GB或以上的 SD Card
4. 將 SD Card 放入，並起動 Raspberry Pi；如果有 HMDI 出 Mon 或 電視，可以看到Raspberry Pi系統起動資訊
5. 正常的話，Raspberry Pi系統應該可以從 Router DHCP 取得網內 IP
6. 使用 putty 登入 raspberrypi, root password is raspberrypi

ckleea

系統和網絡設定

由於部份設定要經 linux command line 進行，請先掌握基本指令使用 putty和 winscp
參考網頁
http://www.bu.edu/tech/support/desktop/software/windows/gsputty/
http://www.bu.edu/tech/support/desktop/software/windows/winscp/

系統設定
(一) 更改 root password

• 用 putty 進入系統 as root
  
• 輸入passwd 更改 your root password
  

2. 更改 pi user password

• login as pi; default password - raspberry
  
• 輸入passwd 更改 your password
  

(二) 網絡設定
基本設定為經 wired ethernet 上網，從router 路由器 DHCP 取得內聯網 Lan IP。
初階使用方法

• 在wired ethernet 上，使用固定 Lan IP
  用 putty 進入系統 as root
  更改 /etc/network/interfaces
  [attach]3002[/attach]
  改為
  [attach]3003[/attach]
  例如 網友的網絡設定為
  <ip-address> = 192.168.1.10
  <netmask address> = 255.255.255.0
  <gateway address> = 192.168.1.1
  
  [attach]3004[/attach]
  儲存檔案，然後
  /etc/init.d/networking reload
  or
  reboot
  
  參考網頁：http://elinux.org/RPi_Setting_up_a_static_IP_in_Debian
  
  
• 經 wireless adaptor 到router 路由器取DHCP派的Lan IP
  

進階使用方法

• 經USB 3G 手指上網
  
• 將wireless adaptor變成 hotspot，經wired ethernet  上網

設定 Asterisk 功能 - 1o

The Asterisk server has been compiled with most common options and has almost all modules available. However, the configuration files are changed to a simpler and cleaner version. All the default configuration files are moved to other directory for backup  (/etc/asterisk.samples/)

By default, Asterisk GUI Management IP is http://your_raspberrypi:8088/

設定 VPN - 1

Softether VPN is installed by default and started when Raspberry Pi is up. All you need is to open the appropriate TCP/UDP ports of your router for VPN connections (SSTP, OpenVPN, IPSec). PPTP will be discussed in next thread.

To manage the Softether VPN server, you need to install the Softether VPN server admin tools for Windows.
At the linux command line, 2 commands are available
- "service VPN status" to check whether the VPN server is running
- "service vpnserver restart" to restart the VPN service.
