Raspberry 使用固定ip..... pppoe

首先你要先去中華電信的網頁申請固定IP加浮動IP..... (比較便宜的方案... 但比較不穩定)

http://service.hinet.net/2004/adslstaticip.php

按下申請....不用錢....

然後他就會秀出你的固定ip.....

接下來就是在RPI那端使用pppoe的連線方式來連線....

使用 pppoeconf 套件

直接從官方套件庫安裝 PPPoE 撥接程式。
sudo apt-get -y install pppoeconf


準備設定撥接參數。
sudo pppoeconf

輸入撥接帳號。
XXXXX@ip.hinet.net

輸入撥接密碼
your_password....

如果帳號跟密碼忘了....就是跑一趟中華電信吧....像我今天就是

最後執行結果如下:

在cmd line的模式下來超頻 on raspberry

sudo vi /boot/config.txt

In this file, you’ll want to add the following two lines:

arm_freq=800
sdram_freq=500

reboot ....and check this frequency by

vcgencmd get_config arm_freq

and it should be

arm_freq=800

Maybe you could use

sudo raspi-config

Again to check it, you can type in

vcgencmd get_config arm_freq

and it should say:

arm_freq=800

You can also check more options by typing:

vcgencmd get_config int

And it should look like this:

arm_freq=800
core_freq=250
sdram_freq=500
disable_overscan=1
boot_delay=1
temp_limit=85

Enjoy!

設定 keyboard 的方法on terminal

如果當你設置keyboard後....發覺要打pi  變成不是pi  例如  60 時

這時候你就會需要用到這一招了...

用nb 遠端連線進去RPI.....


有兩種方式可以重新改變keyboard setting...

method 1:

vi  /etc/default/keyboard
內容如下:
XKBMODEL="pc105"
XKBLAYOUT="tw"
XKBVARIANT=""
XKBOPTIONS="lv3:alt_switch,terminate:ctrl_alt_bksp"

BACKSPACE="guess"

直接去修改....

method 2: 利用tool 去啟動 keyboard configuration

You can change the setting for default system keyboard hardware (e.g. "Generic 105-key keyboard"to "Generic 101-key keyboard") and also the system keyboard layout (e.g. "us-intl" to "us") with the command

sudo dpkg-reconfigure keyboard-configuration

我是選  pc 105 鍵  ->  taiwaniness  -> both....  ->  no 組合鍵

method 3 :  使用  raspi-config  -> keyboard....有時候這個怪怪的
