[ssh] 如果指定 ssh 的 port 和 username

由 A主機透過 ssh 連線至 B主機，預設的 port 是走 port 22，直接以目前A主機的帳號為 ssh 的登入帳號。

由於預設值是無法變更帳號，所以可以利用 .ssh/config 這個檔案來指定 ssh 登入遠端 ssh server 的port 和登入帳號。例：

Host *.tpc.edu.tw
User myadmin
Port 2288

Host mail
User mailadmin
Port 2288

Ubuntu 安裝Chromium

以下操作以Ubuntu 9.10環境為主，如果使用 9.04或其它版本的話，請將步驟1內的紅色文字以符合版本的CodeName來代替：

1. 將下列套件庫加入 /etc/apt/source.list

sudo echo "deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu karmic main" >> /etc/apt/source.list

2. 加入GPG金鑰

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xfbef0d696de1c72ba5a835fe5a9bf3bb4e5e17b5

3.更新套件庫

sudo apt-get update

4.安裝Chromium

sudo apt-get install chromium-browser

[網管教程] 大綱準備中

最近突然覺得單位網管能力有急速下降的趨勢，這似乎是一件令人十分擔憂的現象，小弟的能力雖然不足，不過，準備一下大綱應該還可以，希望內容也能夠逐步來完善它。

一、伺服器系統安裝

1. FreeBSD
2. Ubuntu Server
3. Windows Server 2003(2008) x32(x64) (R2)
   

二、各項服務架設

1. DNS - Bind
2. MAIL - Postfix
   
3. WEB - Apache
4. DHCP
   
5. MRTG
   
6. Database - MySQL

三、虛擬化系統環境

1. VMWare Server (VirtualBox)
   
2. VMWare ESXi 4 (vShere)
3. XEN 5.5
4. Microsoft Hyper-V
   

四、雜項

1. i-Chip 主機管理
   
2. putty 操作(ssh client)
   
3. vi 文字編輯器
4. 其它常用命令列指令

• find, locate, whereis
• df, du
• /etc/init.d/ (linux) , /etc/rc.d (freebsd)
  

[網管] 利用 nmap 取得各個機器的 ip 及網卡號碼

1. 先安裝 nmap 工具

sudo apt-get install nmap

2. 以root 權限執行下列指令 (紅色部分請依自己的網路情況調整)

sudo nmap -v -sP 10.xxx.141.0/24 |grep -v "down"

如果希望每次執行完的結果存成不同檔案，可以把步驟2修改如下：

nmap -v -sP 10.xxx.141.0/24 |grep -v "down" > ~/mylan_`date +%Y%m%d%H%M%S`.txt

上列指令會將結果存至家目錄。

[Develop] 教職員基本資料不顯示已停權的人員

在mysql 建立 "teacher_online"

CREATE
    /*[ALGORITHM = {UNDEFINED | MERGE | TEMPTABLE}]
    [DEFINER = { user | CURRENT_USER }]
    [SQL SECURITY { DEFINER | INVOKER }]*/
    VIEW `school`.`teacher_online`
    AS
    (
    select teacher.*
    from
    userights
    inner join
    teacher
    on userights.account = teacher.account
    WHERE
    userights.pause=0
    )

修改檔案：
school/basic/index_intro.php
school/basic/index_intro_area.php

修改內容：
將所有的 SQL 指令中的 " from teacher " ==> " from teacher_online "
