ldap connect AD

開始:
1. 建立 IIS SSL
2. 將 CA Certificate 加入至 jre keystore 裡
3. JNDI 連 AD

1. 建立 IIS SSL:
Install Windows 2003 Server:

Install AD:
Start -> Run -> dcpromote
domain name : joeyta-DOT-local
NT domain name : joeytaserver
即 Fully Qualified Domain Name (FQDN) 為 joeytaserver.joeyta-DOT-local

先安裝 IIS , 再安裝 CA.

Install IIS:
Start -> Programs -> Administrative Tools -> Configure Your Server Wizard
->> Next -> Next -> Application server (IIS, ASP.NET) -> Next

進入 http://joeyserver.joeyta.local/postinfo.html 表示安裝成功.

Install CA:
Start -> Settings -> Control Panel -> Add or Remove Programs
->> Add/Remove Windows Components
選擇 Certificate Services -> Next
選擇 Enterprise root CA -> Next
Common name for this CA: testca -> Next

進入 http://joeyserver.joeyta.local/CertSrv 表示安裝成功.


Generating a Certificate Signing Request:
Start -> Programs -> Administrative Tools -> Internet Information Services (IIS) Manager
->> Internet Information Services -> (local computer) -> Web Sites
-> > 右鍵點選 Default Web Site -> Properties
選擇 "Directory Security" -> Server Certificate
->> Create a new certificate -> Prepare the request now, but send it later
一直按 Next , 需要注意的是 Common name 必須為 joeyserver.joeyta.local, 這是給使用者連 ssl 的 website.
最後產生 certificate request file , 預設為 c:\certreq.txt


Request a certificate on CA:
進入 http://joeyserver.joeyta.local/CertSrv
按 Request a certificate -> advanced certificate request
-> Submit a certificate request by using a base-64-encoded CMC or PKCS#10 file, or submit a renewal request by using a base-64-encoded PKCS#7 file
使用 notepad 打開 c:\certreq.txt , copy c:\certreq.txt 內容貼至 Saved Request:
Certificate Template 選擇 Web Server, 按 Submit
然後點選 Download certificate , 將 certnew.cer 儲存至 c:\certnew.cer


Installing a Certificate:
Start -> Programs -> Administrative Tools -> Internet Information Services (IIS) Manager
->> Internet Information Services -> (local computer) -> Web Sites
-> > 右鍵點選 Default Web Site -> Properties
選擇 "Directory Security" -> Server Certificate
->> Process the pending request and install the certificate -> Next
Path and file name: c:\certnew.cer -> Next
SSL port this web site should use: 443 -> Next -> Next -> Finish


2. 將 CA Certificate 加入至 jre keystore 裡:
進入 http://joeyserver.joeyta.local/CertSrv
點選 Download a CA certificate, certificate chain, or CRL
點選 Download CA certificate , 然後下載並改名為 c:\testca_cert.cer

然後執行 command:
c:\temp>keytool -import -alias testca_cert -file "/testca_cert.cer" -keystore "/jdk1.5.0_09/jre/lib/security/cacerts" -storepass "changeit"

出現 Trusted this certificate? 按 "y" 即新增成功.


3. JNDI 連 AD:

cctg: Using ldap api to connect MS Active Directory

Ubuntu 好用軟體

edonkey - aMule

sudo apt-get install aMule

不用說了吧，反正就是那回事，中文，日文都 ok 的啦

IM - Gaim(Pidgin)

萬用 Instant Messager，Ubuntu內建，新版改名叫 Pidgin，變得漂亮多了

BBS - PCManX

sudo apt-get install pcmanx-gtk2

好用的 BBS client，記得要換字型比較好看

Packet Sniffer - Ethereal

sudo apt-get install ethereal

看封包內容的軟體，功能強大，不過我只拿來 debug http 的 resquest/response

BT - Deluge

sudo apt-get install deluge-torrent

就是 BT，gnome 是有內建，但是那個太陽春了，換這個 python 寫的吧

看漫畫 - Comix

sudo apt-get install comix

這個超讚，用電腦看漫畫必備！可以設定左右兩頁合併成一頁，也支援右頁翻到左頁 (漫畫都是右到左)。當然你要拿來瀏覽一般圖片也行，速度很快。

向量繪圖 - Inkscape

sudo apt-get install inkscape

雖然我不會美工，但有時候還是得改一些 icon，或是做一些簡單的 logo。inkscape 用起來挺直覺的，連我這個繪圖白吃都玩的起~

安裝外部軟體 - Automatix

sudo apt-get install automatix2

Skype, Adobe Reader, Windows codec, 讀寫 NTFS 等等涉及版權的軟體安裝起來都超麻煩的，這時 Automatix 就派上用場了，點幾下那些難纏的軟體通通裝好設定完全。爽~

錄音 - Audacity

sudo apt-get install audacity

多軌錄音軟體，介面很醜... 不過夠我錄音樂用了。

看影片 - vlc

sudo apt-get install vlc

你什麼 codec 都可以不裝，就是不能漏掉這個 vlc，連 wmv9 都可以看，真是天賜啊

字典 - 星際譯王

sudo apt-get install stardict

沒有這個字典活不下去

virtual machine - VirtualBox

sudo apt-get install virtualbox

我已經放棄 vmware 了，vmware player 太陽春，vmware workstation 要錢，vmware server 安裝太麻煩。每次 kernel 升級 vmware 就要重新 compile... etc 真是煩死了。一氣之下轉換到 virtualbox，從此過著幸福快樂的日子。還死守在 vmware 的同胞們快點換吧~

screen action - brightside

sudo apt-get install brightside

裝了這個就可以設定滑鼠碰觸畫面角落，開啟特定程式或是顯示桌面，我用慣 mac 的滑鼠顯示桌面了，所以裝這個來模擬。

Palm - J-Pilot

sudo apt-get install jpilot

如果你跟我一樣還在用那個不上道的 palm (treo650)，這個可以解決 sync 的問題，Big5 中文也通喔！(如果弄得到 iphone 我就把 treo 給丟了)

nVidia - envy

sudo apt-get install envy

nVidia 的用戶，一定得安裝 envy。這個軟體可以解決所有有關 nVidia 的問題，XWindow 裝不起來嗎？beryl 特效弄不出來嗎？想裝 nVidia 官方的 driver 嗎？裝 envy 就對了。我的 LCD 是 LED 背光，因此顏色是偏藍的，這時就得靠 nVidia 官方的 nvidia-setting 這個工具來微調了。用 envy 安裝官方 driver 後，輕輕鬆鬆搞定！

Google Desktop

http://desktop.google.com/linux

google 最新推出的 linux 版桌面搜尋，安裝後 ctrl 兩下就能搜尋囉，還蠻好用地，算是補足 linux 一直欠缺的功能。啥？你說之前已經有 beagle 了？拜託，那是用 mono 寫得耶，好不容易轉到 linux 了，幹嘛還被 ms 套牢？

中文字型 OpenDesktop Font

http://www.opendesktop.org.tw/modules/news/article.php?storyid=106

經由 OpenDesktop 團隊的努力，我們有全世界最漂亮、最清楚的中文字型囉。Mac上字型透過獨家的 render 技術產生的字型很棒，但就算 render 技術再強，永遠也比不上一個個精雕細啄的點陣字啊！

其他太基本的 gcin, java, eclipse, gimp, remote desktop 等等就不提了
