檢查是否有載入無線網路模組
# lsmod | grep bcmdhd

如果沒有的話
# echo bcmdhd >> /etc/modules-load.d/cubie.conf

建立無線網路設定檔
# cp /etc/netctl/examples/wireless-wpa /etc/netctl/wlan0[@more@]

在 Fedora / CentOS Linux 可以在 /etc/rc.d/rc.local，在 Debian / Ubuntu Linux 可以在 /etc/rc.local 中設定開機要執行的一些功能，如：防火牆的設定之類的功能，不過在 Arch Linux 中似乎沒有這一個檔案的存在，但可以用替代的方式，達到這種功能。

原本看到在 Cubie Truck 下載區有 Ubuntu 14.04 非常高興，馬上下載下來使用！
下載網址：http://dl.cubieboard.org/software/a20-cubietruck/ubuntu-14.04/

預設登入的帳號及密碼：root / cubie
不過開機完成後，發現進入的是文字介面，這也還好，反正可以透過網路加裝其它套件，然後發現竟然連 eth0 也沒抓到，這真的是給 Cubie Truck 用的版本嗎？

預設的 Ubuntu Desktop 是英文版的介面

底下是中文化的過程
[@more@]$ sudo locale-gen zh_TW.UTF-8
Generating locales…
  zh_TW.UTF-8… done

$ sudo update-locale LANG=zh_TW.UTF-8
$ sudo update-locale LANGUAGE=zh_TW.UTF-8

$ sudo apt-get install fonts-arphic-uming ttf-arphic-ukai language-pack-zh-hant firefox-locale-zh-hant poppler-data language-pack-gnome-zh-hant cmap-adobe-cns1

安裝中文輸入法 gcin
$ sudo apt-get install gcin

重新登出登入後，介面就中文的了！

但 gcin 的圖示無法出現在工作列上，參考下面的連結
http://www.ubuntu-tw.org/modules/newbb/viewtopic.php?post_id=217464#forumpost217464

在上面的狀態列上按著「Win」+「Alt」再加上「滑鼠右鍵」，
接著按下「加入面板」就會跳出加入面板的視窗，
這時向下找到「程式狀態通知區」後選擇它並加入，
這樣就會看到 gcin 狀態列了！

但出現圖示之後，發現並不是所有的程式都能使用，試了幾個程式，發現 firefox / leafpad 可以，但 terminal / gedit 則不行，這是…..

所以決定先放棄這一個版本。

因為 Ubuntu root 分割區的大小實在有些小，稍微安裝一下套件就快滿了！
$ df -h

安裝 Ubuntu Desktop 傳統介面，因為不習慣使用新的介面，並不是 Unity 新的介面有什麼不好，就像 Windows 8 / 8.1 把開始功能表移除一樣
$ sudo apt-get install gnome-session-fallback

改成傳統介面

安裝方式：
$ sudo apt-get install samba tdb-tools

修改設定檔 /etc/samba/smb.conf
$ grep -E -v ‘^$|^#|^;’ /etc/samba/smb.conf
[@more@]
建立使用者的 Samba 帳號及密碼
$ sudo /usr/bin/pdbedit -a linaro

啟動 Samba Server
$ sudo /etc/init.d/nmbd start
$ sudo /etc/init.d/smbd start

在 Windows 7 上測試
在檔案總管上方列輸入 IPUsername

輸入帳號及密碼

應該可以瀏覽使用者的家目錄

因為之前的做法是無線網路連線時，不用輸入金鑰，任何人都可以連線，存在安全性上的問題，所以在這一篇做修正。

可以使用 
wpa_psk=ee07bee15c9c33bf7bcc53d84aac17e2b83f82476f96e32efcd03d716d99a4d2
或
wpa_passphrase=123456789
# cat /etc/hostapd/hostapd.conf
interface=wlan0
driver=nl80211
ssid=CubieTruck
channel=11
hw_mode=g
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_psk=ee07bee15c9c33bf7bcc53d84aac17e2b83f82476f96e32efcd03d716d99a4d2
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP[@more@]但在使用 Lubuntu 內建的 hostapd 套件時
執行之後，使用者連線之後會出現許多錯誤訊息

在網路上搜尋的結論是，Cubie Truck Lubuntu 內建的 hostapd 版本過舊，不支援 wpa 的方式連線

解決方式：
移除原先安裝的 hostapd
# apt-get remove hostapd

下載已經編譯好的版本
# wget https://github.com/igorpecovnik/Cubietruck-Debian/raw/master/bin/hostapd21.tgz

解壓縮
# tar xvzf hostapd21.tgz

複製解壓縮完成的檔案到 /usr/sbin
# cp hostapd hostapd_cli /usr/sbin

檢查版本
# hostapd -v
hostapd v2.1
User space daemon for IEEE 802.11 AP management,
IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator
Copyright (c) 2002-2014, Jouni Malinen <j@w1.fi> and contributors

再執行一次，使用者連線時便不會出現錯誤訊息
# hostapd /etc/hostapd/hostapd.conf

以 Windows 7 測試連線時，也會出現要輸入 網路安全性金鑰 的畫面

因為 Cubie Truck 內建有無線網路卡，之前有試著把 Raspberry Pi 做成無線 AP，也在網路上找了一下相關的資料。
參考網站：

底下的做法是不用做認證即可上網，比較不安全
安裝 hostapd 
$ su –
# apt-get install hostapd [@more@]
建立設定檔
# vim /etc/hostapd/hostapd.conf
interface=wlan0
driver=nl80211
ssid=CubieTruck
channel=11
hw_mode=g
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0

安裝 DHCP Server
# apt-get install isc-dhcp-server

設定由 wlan0 介面來發送 IP
# sed -i ‘s/INTERFACES=””/INTERFACES=”wlan0″/’ /etc/default/isc-dhcp-server

設定 DHCP Server
# grep -v ^# /etc/dhcp/dhcpd.conf | grep -v ^$
ddns-update-style none;
option domain-name “example.org”;
option domain-name-servers ns1.example.org, ns2.example.org;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet 172.16.0.0 netmask 255.255.255.0 {
    range 172.16.0.1 172.16.0.10;
    option domain-name-servers 168.95.1.1;
    option domain-name-servers 8.8.8.8;
    option routers 172.16.0.254;
}

設定無線網路卡網路組態
# vim /etc/network/interfaces
auto wlan0
iface wlan0 inet static
        address 172.16.0.254
        netmask 255.255.255.0
        network 172.16.0.0
        broadcast 172.16.0.255

重新啟動網路
# /etc/init.d/networking restart

重新啟動 DHCP Server
# /etc/init.d/isc-dhcp-server restart

設定防火牆
# vim /etc/firewall.wifiap
#!/bin/bash
IPTABLES=/sbin/iptables
$IPTABLES -F
$IPTABLES -F -t nat
$IPTABLES -X

$IPTABLES -P INPUT ACCEPT
$IPTABLES -P OUTPUT ACCEPT
$IPTABLES -P FORWARD ACCEPT

modprobe ip_conntrack
modprobe iptable_nat
modprobe ip_conntrack_ftp
modprobe ip_nat_ftp

echo 1 > /proc/sys/net/ipv4/ip_forward
$IPTABLES -t nat -A POSTROUTING -j MASQUERADE

執行防火牆規則
# sh /etc/firewall.wifiap

執行 hostapd 開啟熱點功能
# hostapd -B /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
Failed to create interface mon.wlan0: -95 (Operation not supported)
Using interface wlan0 with hwaddr 02:1a:11:fe:c0:3d and ssid ‘CubieTruck’

設定開機時立即執行 
# sed -i ‘/^exit 0/ish /etc/firewall.wifiap’ /etc/rc.local
# sed -i ‘/^exit 0/i/usr/sbin/hostapd -B /etc/hostapd/hostapd.conf’ /etc/rc.local

使用 Windows 7 來做測試
選擇 CubieTruck 無線網路

選擇  連線

在  命令提示字元輸入 ipconfig 查看取得的 IP
C:> ipconfig

測試是否可以正常 Ping 到外部網路

DNS 查詢也沒有問題
