Dependency Walker 2.2(深看程式背後運作)

Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.

Dependency Walker is also very useful for troubleshooting system errors related to loading and executing modules. Dependency Walker detects many common application problems such as missing modules, invalid modules, import/export mismatches, circular dependency errors, mismatched machine types of modules, and module initialization failures.

Dependency Walker runs on Windows 95, 98, Me, NT, 2000, XP, 2003, and Vista. It can process any 32-bit or 64-bit Windows module, including ones designed for Windows CE. It can be run as graphical application or as a console application. Dependency Walker handles all types of module dependencies, including implicit, explicit (dynamic / runtime), forwarded, delay-loaded, and injected. A detailed help is included.

Dependency Walker is completely free to use. However, you may not profit from the distribution of it, nor may you bundle it with another product.

Speccy

System Information

SpeccySpeccy is an advanced System Information tool for your PC. We're still bug fixing, but have just released a Public BETA version for you to download!


Speccy1.png

Overview

What's in your computer?  If you're like most of us, you can probably name the processor (Intel or AMD, Celeron or Pentium), maybe how much RAM it has, and maybe how big the hard drive is.
When you go to a computer store and see all the bright shiny PCs laid out next to each other, most will have tags or stickers indicating the:
  • Processor brand and model
  • Hard drive size and speed
  • Amount of memory (RAM)
  • Graphics card
  • Operating system
Two or three years later, when it comes time to upgrade your computer, that tag or sticker may be long gone. Speccy was designed as a free electronic "what's inside" sticker for your PC.
Isn't this information in Windows?
Yes and no. Some of the basic information can be found by right-clicking My Computer and then clicking Properties. The General tab lists some statistics, and the Device Manager on the Hardware tab lists all of the hardware you've got installed. But it misses out lots of information that you need.
Speccy will give you detailed statistics on every piece of hardware in your computer. Including CPU, Motherboard, RAM, Graphics Cards, Hard Disks, Optical Drives, Audio support. Additionally Speccy adds the temperatures of your different components, so you can easily see if there's a problem!
Why do I need Speccy?
At first glance, Speccy may seem like an application for system administrators and power users. It certainly is, but Speccy can also help normal users, in everyday computing life.
If you need to add more memory to your system, for example, you can check how many memory slots your computer has and what memory's already installed. Then you can go out and buy the right type of memory to add on or replace what you've already got.
If you're going to be selling your PC, you can use Speccy to quickly list out the components. Or, if you're buying a PC, you can use Speccy to check that the computer has what the label says it has.
Also, Speccy comes in handy for support. If you're on the phone with technical support and they want to know what video card you have installed, there's no need to hunt around Windows. Speccy has all the information on one easy-to-understand screen.

Download

Please note this is a beta version of Speccy and should only be used by advanced users on test machines. We recommend you wait for a final release version before downloading.

SSH設定特定使用者帳號可以登入(轉自Jerry_IT資訊技術手札)

SSH設定特定使用者帳號可以登入

使用SSH如果要高點安全性的話,可以嘗試將特定使用者加入可以連線SSH的帳號,其他就不可以登入

編輯ssh設定檔,sshd_config,輸入vi /etc/ssh/sshd_config


在設定檔的最後一行輸入AllowUsers 帳號,此行預設是沒有的,下列的root及tom就是可以連線SSH的帳號,除了這兩個帳號,系統其他的帳號就不可以SSH登入,不過建議不要使用root可以SSH,畢竟安全性考量,用其他帳號登入後再su切過去


存檔後,請重新啟動SSH。


那測試一下,將不在允許名單的帳號jerry,登入就會出現密碼驗證過不去,再去試看看可以登入的帳號,如果都OK,代表就設定成功


不過用可以登入的帳號後,還是可以su切過去不可以登入的帳號做使用。

RAW拍攝轉換

Digital Negative (DNG)

Digital Negative

The public, archival format for digital camera raw data

Raw file formats are becoming extremely popular in digital photography workflows because they offer creative professionals greater creative control. However, cameras can use many different raw formats — the specifications for which are not publicly available — which means that not every raw file can be read by a variety of software applications. As a result, the use of these proprietary raw files as a long-term archival solution carries risk, and sharing these files across complex workflows is even more challenging.
The solution to this growing problem? The Digital Negative (DNG), a publicly available archival format for the raw files generated by digital cameras. By addressing the lack of an open standard for the raw files created by individual camera models, DNG helps ensure that photographers will be able to access their files in the future.
Within a year of its introduction, several dozen software manufacturers such as Extensis, Canto, Apple, and iView have developed support for DNG. And respected camera manufacturers such as Hasselblad, Leica, Casio, Ricoh, and Samsung have introduced cameras that provide direct DNG support. Learn more

Windows 7 USB/DVD Download Tool

Overview

When you purchase Windows 7 from Microsoft Store, you have the option to download an ISO file or compressed files. The Windows 7 USB/DVD Download tool allows you to create a copy of your Windows 7 ISO file on a USB flash drive or a DVD. To create a bootable DVD or USB flash drive, download the ISO file and then run the Windows 7 USB/DVD Download tool. Once this is done, you can install Windows 7 directly from the USB flash drive or DVD.

The ISO file contains all the Windows 7 installation files combined into a single uncompressed file. When you download the ISO file, you need to copy it to some medium in order to install Windows 7. This tool allows you to create a copy of the ISO file to a USB flash drive or a DVD. To install Windows 7 from your USB flash drive or DVD, all you need to do is insert the USB flash drive into your USB port or insert your DVD into your DVD drive and run Setup.exe from the root folder on the drive.

Exchange 2003: Using the Mailbox Manager

One of the new features that was implemented in Exchange 2000 SP1 is the Mailbox Manager.  With the Mailbox Manager an Exchange Administrator has the ability to control the content of a user’s mailboxes.


Creating a Mailbox Manager Policy

1.       Open the Exchange System Manager.
2.       Navigate to the Recipient Policies container (Fig. 1).



Figure 1
      3.       Right click over Recipient Policies and select New > Recipient Policy.
    
 4.       In the New Policy dialogue box (Fig. 2), select Mailbox Manager Settings and click OK.

Figure 2

      5.       In the Properties dialogue box (Fig. 3), enter a meaningful name.
 

Here you can also apply a filter to the policy so that it only affects a subset of your users.  If you do not modify the filter it will apply to all users.


Figure 3

     
  1. Click on the Mailbox Manager Settings tab (Fig.4).  It is here that we will set the criteria that a message must meet in order for the policy to process it. 


Figure 4


With the options in the When Processing a Mailbox: dropdown list, we have the ability to select what action you would like Exchange to take.  The options available to us are:

·          Generate Report Only
·          Move to Deleted Items Folder
·          Move to System Cleanup Folders
·          Delete Immediately

We then have the ability to specify the type of messages that this policy will effect, the age of the item and or the message size (the size the message must be over).

Our policy is going to be set to Move to System Cleanup, for Inbox and Sent Items older than 2 days (Fig. 5).



Figure 5

We want the user to be sent a mail notification of the action taken, so if we select the checkbox Send Notification Mail to User After Processing (Fig. 6), we can also customize the message that the user will see but clicking on the Message button (Fig. 7).

 

Figure 6
 





Figure 7

  
OK, so once we have set the options for our policy the next step is to configure when the server will actually process the policy.

7.       Right click on the server in Exchange System Manager and select Properties, select the Mailbox Management tab (Fig. 8)



Figure 8



From here we can select when the Mailbox Management Process will run, what level of reporting we would like to produce and who is designated as the administrator.

When selecting the schedule that you would like the Mailbox Management Process to use, the interval that you specify will directly impact the performance of your server.

That pretty much covers the Mailbox Manager in Exchange 2000, and this neat feature will give administrators the ability to control their user’s mailboxes.

ESXi 4.0 SSH連線設定步驟 (轉自Jerry_IT資訊技術手札)

ESXi 4.0 SSH連線設定步驟

ESXi某些情況需使用SSH才可以開啟設定,SSH預設是關閉的,所以必須要手動開啟。


一開始先在ESXi主機,按下ALT+F2,進入文字編輯模式


在此畫面輸入unsupported,輸入時看不到任何字,輸入完後,按下Enter,如果輸入正確,你會進入輸入密碼的畫面,如果入錯誤,請按下ALT+F1,回到ESXi預設管理介面,再按一次ALT+F2到文字模式輸入。注意ESXi 3.5或3.0畫面有可能不太一樣,做法都一樣。


輸入root密碼。


下圖為正確進入文字介面


開啟SSH就要編輯inetd.conf檔案,輸入vi /etc/inetd.conf


inetd.conf檔案內有下列幾行文字


因為目前IP為IP V4,所以將tcp那行的SSH的#號取消掉,然後存檔


關機就要按回預設管理介面,輸入ALT+F1,再按下F12,進行關機


關機前必須確認密碼才可以關機。


選擇F2,進行關機


重開機好後,使用putty或PieTTY進行SSH連線


出現下圖代表可以正常連線




ESXi內建就有圖形的遠端管理工具VMware vSphere Client,在開啟SSH後,在瀏覽器輸入該主機IP,就可以進入下載VMware vSphere Client,進入前按下確定憑證。


按下繼續瀏覽此網站


按下Download vSphere Client,下載工具,並進行安裝。

OS FreeNAS

仲想自己寫,不過人家比我寫得更好,還是轉貼把Orz:

轉自http://tw.network01.net/modules/newbb/viewtopic.php?topic_id=94&forum=8

打造免費的全能型NAS - 安裝教學

筆者在很久之前就試用過一套免費的Open Source軟體-FreeNAS來 架設一台NAS網路存儲伺服器。無奈當時FreeNAS才發展到0.1X的版本,功能少又不穩定,再加上設定不人性化,所以已很久沒去碰它了!但在今日各 家廠商所推出的NAS功能越來越多,速度又能越來越快的時候,筆者心裡想著是否有辦法可以手動打造一台免費的NAS來跟"要花錢買"的NAS比美呢? 結果在網路上搜尋了一下後,又回到了FreeNAS的懷抱。至於為什麼這次筆者又相中了FreeNAS呢,因為它目前的功能已發展到可以跟主流NAS廠商 的產品比美的地步了(支援PHP網頁伺服服器,加密型FTP,BT下載,UPNP,iTune等等),甚至有部份只出現在企業用高階產品的功能(如 iSCSI),FreeNAS都已包含其中,所以筆者不得不好好的再重新對FreeNAS來一次大評測!



不 過,雖然說現在FreeNAS已不是當年的陽春玩具,而且主要功能都專精在企業NAS的應用上,但是卻甚少看到真正有企業把FreeNAS應用到 Production Site上,頂多就是個別部門自己使用而已,歸根究底,還是一個"責任"問題!原則上,NAS是歸IT部門管理的,但是IT部門的價值在台灣並沒有被認真 的看待,一般老板的認知就是公司IT相關的東西不出任何問題是應該的(老板大都不理解一個穩定的系統是MIS或IT花了多少心血在上面),一但出現任何問 題就把問題怪在MIS或IT人員的頭上,IT部門可以說在很多企業中是個吃力不討好的部門。這也就造成了這樣一個局面︰雖然很多免費的Open Source防火牆,NAS,路由器等功能及穩定性都不錯,但是都沒有被應用在企業環境中!原因無它,如果您是IT人員,用免費的東西,不出事的話老板通 常是不會感謝您為公司節省了開支,但是一出事,鐵定就是您"貪小便宜"的錯!而且...花錢買廠商昂貴的設備也不是花您自己口袋裡的錢,反正是花公司的, 而且出了事只要一通電話叫廠商或SI過來處理就好,何樂而不為呢~ 最後,就是這樣造成了空有好的Open Source產品卻無法普及的情況~

好吧~ 吐了一些IT人的心聲後,開始切入正題,要想自己打造一台全功能的NAS系統,第一件事就是找一台電腦,要真正使用的話建議找台新的電腦,不然一般的中古舊電腦也就可以勝任了!
筆者找了一下,在牆角處發現了一台已退役的準系統~ 好吧,外型也蠻像一台專業的NAS設備,就選它吧~



看起來好像很新的樣子,方方正正



原來都已生銹了~ 要先好好打開檢查一下還能不能用



如 果只是想試玩一下FreeNAS,其實用VMware等虛擬機器軟體就可以了,如果真的要找台電腦把它變成NAS使用,最好就像筆者一樣先打開來看看主機 板上的電容有沒有"爆漿"(看電容的頂端有沒有裂開或流出爆狀液體)! 如果發現主機板上有"爆漿"的電容就代表你的電腦能打開也不一定會穩定工作了,用這樣的電腦當NAS,無疑就是跟儲存在上面的資料"過不去",而且如果你 還跑RAID,很可能在某一次當機重開後就甚麼都消失了~



這台電腦果真舊,上面還插了一張10Mbps的網卡 >.<



好多灰塵喔~ 還是先清一清比較好,電容倒是都好好的,沒有找到"爆漿"電容!



一切都檢查好沒有問題後,就可以去官網下載程式回來了! http://www.freenas.org



直接"殺"它的最新版LiveCD,V0.69b4



點擊Download後就會被導到SOUCEFORGE.NET開始下載



下載完成後是一個ISO,當然就是要把它燒錄到一片CD上~



燒錄中,一下子時間就好了~



燒好後就拿它來開機就可以了(如果沒辦法用光碟開機,可以先進BIOS確定有優先從光碟機開機,再來看看是不是燒錄失敗了)



開機到一半後會進入一個選單,這裡直接選1或甚麼都不動,等10秒它也會自動選1繼續跑下去的~



開機完成後就會停在這個畫面,因為是第一次安裝,所以選9 (Install...)



安裝的方式有分3大類,可以把系統裝在CF或USB Disk上,也可以把它直接安裝在第一顆硬碟中,然後在同一顆硬碟中再切一個分割區來當NAS的資料儲存區使用,這裡選擇3就是這種安裝方式~



它會警告您說這樣做的話硬碟上原本的資料就會被清掉...



接下來會要求您選擇從哪一台光碟機來進行安裝,現在一般每台電腦應該都只有一台光碟機了~ 所以就是它...不用選了



選擇安裝到那個硬碟,筆者的這台電腦也只有一顆IBM的20G硬碟,所以也就是它!



這邊就用預設的128MB便可~



接下來又會回到黑黑的畫面中開始進行安裝,過程中會要求你按一下"Enter"



完成後就點"Exit"離開安裝程式



最後選7,重新開機就可以了!這時候也可以把安裝光碟退出來了!



確認重開~



筆者特別把以上整個的過程錄成一段Video給大家參考用~



重新開機後,這次就算沒放安裝光碟進去,也可以正常開機並進入這個選單畫面了!這次也是一樣,選1或等10秒



等到系統停在這個選單畫面時,其實已開機完成!除非你的電腦有多於1張網卡或想改掉預設的IP位置(選擇1跟2設定),否則現在就可以透過同網段中的其它電腦連上它的網頁管理介面(WebGUI)做設定了!



先以另一台電腦PING PING看看預設的192.168.1.250通不通~



確定192.168.1.250有通後,就可以打開瀏覽器輸入 http://192.168.1.250 ,並輸入預設的使用者名稱及密碼(admin/freenas)



一切正常的話您就可以看到新的FreeNAS設定介面了!(以前舊的介面是用M0N0的,比較不好用)



FreeNAS有支援多國語言,不管正體中文或簡體中文均在支援之列!不過接下來的教學及評測我們仍然使用英文介面,順便可以學學英文嘛~ 哈哈



這是目前FreeNAS有支援到的功能!很多不同需求的功能也均在支援之列了!不錯吧~


接下來的下一篇文章,我們會測試它的iSCSI功能,也會跟SAMBA比較一下看看各自的效能表現如何~

SCSI(Small Computer System Interface)大家可能以前已聽過,回想當年是民用IDE,企業用SCSI的時代,那條排線就硬是比人家的IDE寬很多,速度又快!SCSI的相關 產品可是當年很多人流口水想要玩玩的東西。不過這回我們不是要研究SCSI,而是要試試iSCSI,一種技術及通訊協定把SCSI指令包在IP封包中來傳 送資料。iSCSI(又稱為IP-SAN)簡單來說可以想成以一般的網路線來當成SCSI的傳輸線傳資料~

(圖片出處: 鳥哥的Linux網站)


透 過這種神奇的東西~ 一台iSCSI伺服器上的硬碟可以被作業系統"誤認"為本機硬碟!利害吧~ 被"誤認"為本機硬碟後,您可以對它做的事就多了,設定權限,把它格式化成不同的檔案系統,壓縮硬碟,或作為了資料庫的儲存裝置等等)...這都是 SAMBA把一個分享(Share)掛載(Mount)成一個Driver所無法提供的優點。

(圖片出處: IBM網站)


而 且最重要的是,用SAMBA來傳檔其實是不太穩定,如果你傳的東西又多又小,那十之八九會傳送到一半的時候跟你說出現問題中斷。其中原因,就是因為 SAMBA是以File level來運作,而iSCSI卻是以Block Level來運作!效能上也會比SAMBA來得好!所以,iSCSI其實是常見於大型企業的環境中,iSCSI在個人或中小企業的環境中是甚少會發現的, 除非是一些動畫設計的中小企業,否則一般是沒有需要用到iSCSI這個東西的!iSCSI的目的就是要為X貴的FC-SAN (Fibre Channel - Storage Area Network)提供另一種相對便宜的選擇,現在除了速度跟穩定性方面還未能追上FC-SAN以外,其實IP-SAN是非常有優勢的!

iSCSI的導入成本相比FC-SAN真的是非常的便宜,首先是可以省掉一張上萬元的HBA(Host Bus Adapters)卡

(圖片出處: adaptec網站)


又 不用特別的SAN Switch,一堆光纖線跟不便宜的Tranceiver也可以省下來!簡單使用iSCSI的話其實只要有乙太網路交換機(Ethernet Switch)、網路線跟電腦上的網卡就可以了,而且現在新的伺服器作業系統大多已內建了iSCSI的驅動程式(iscsi initialator),使用上可以說比FC-SAN方便多了,技術門檻也比較低!

現在要開始設定了,回到 FreeNAS的Web GUI中。因為在上一篇文章-打造免費的全能型NAS - 安裝教學安裝好系統時,並沒有完成相關硬碟設定的作業,所以接下來就是先把我們的硬碟及儲存空間準備好給FreeNAS使用!先點一下"Disks",再點一下"Management"就可以進入到硬碟管理頁面~



再來點一下圖中的"+"號新增硬碟給系統使用



因為筆者的電腦只安裝了一顆IBM的20G硬碟,所以在DISK的地方也只偵測到一顆硬碟,這裡有一個地方要注意的是"Preformatted File System"要選UFS!,其他設定依您個人需求就可以了~



這邊的設定方式還是跟FreeNAS的前身M0N0防火牆一樣,設定後都要點一下"Apply Changes"來讓設定生效!



完成後就可以看到上一張畫右下角的狀態(Status)已從"Initializing"變成"ONLINE"了,這樣這一步設定就代表成功了!



硬碟準備好後,接下來就是要把儲存區掛載到系統上去,這時候點Disks->Mount Point



也是一樣,點一下圖中的"+"號來新增一個掛載區



因為我們之前是選擇系統及資料分割區存在同一顆硬碟上,所以記得設定"Partition"的地方要選2,也順便把這個掛載區設一個SHARE名稱



最後設定完成點了"Apply Changes"後看看Status的地方是不是顯示"OK","OK"就代表這一步也成功了!



為了可以突顯iSCSI優勝的地方,就必須要有比較,這就來跟我們常用的SAMBA比比看。所以要來這邊先把SAMBA設好,點"Service"->"CIFS/SMB"



由於只是要測測效能而不是要真實使用,所以認證(Authentication)的部份就設成"Anonymous",也就是不需認証,連上就可以用。還有右上角的"Enable"別忘了打勾喔~



SAMBA被起用後,就可以來設定網路分享資料夾了,也是點一下"+"新增



這半年來很多NAS廠商都新增了網路分享資料夾的"資源回收筒"功能(Recycle Bin),當然在FreeNAS上也沒有缺席~



設定完成!(記得有"Apply Changes"時都要點下去喔)



現 在就打開另一台電腦,透過"網路芳鄰"的方式來連看看FreeNAS的SAMBA伺服器,方式很簡單,打開檔案總管後輸入\\192.168.1.250 便可!(如果您的FreeNAS沒在用預設的IP 192.168.1.250,就輸入"\\您FreeNAS所設定的IP"),完成後就會看到我們剛剛新增的網路分享資料夾"N01Share"



這台老電腦的CPU為AMD Authlon 1600+ (1.4G),內建一張100M的網卡,測試一下,傳個大檔案上去FreeNAS,結果表現算是不過不失,平均都有超過10MB/s (100Mbps網路的理論極速為12.5MB/s)



而CPU使用率方面,果真也用不光,平均在30%~50%間跳動!筆者相信如果改成一張1G的網卡,效能上還有不少的成長空間!



SAMBA 的簡單測試結果有了,接下來就要開始設定iSCSI了~ 因為Windows Vista已直接內建了iSCSI的驅動程式(iscsi initialator),所以Vista要使用iSCSI是非常方便的,而XP卻要自己另外安裝iscsi initialator,不過微軟也有兔費提供下載!
要啟用Vista的iSCSI服務,要先進入控制台後點左下角的"設定iSCSI啟動器",接下來選"是"就可以了~



接下來就會自動進入到設定的頁面!啟動器名稱會由系統自動產生,它是一個唯一(unique)的名稱



接 下來就可以回到FreeNAS的GUI中,進入"Services"->"iSCSI"後需要先新增一個"Extent",而"Extent"可以 直接找一台硬碟以1:1對應的方法或建立一個虛擬檔案的方式來達成!筆者這次就以虛擬檔案的方式來建立一個5G的"Extent",虛擬檔案的好處就是應 用彈性比較高,但是CPU使用率也會來得相對高一些~



建完"Extent"後還需要新增一個"target"(使用剛才建立好的extent0),這邊也可以設定"只允許"那一個subnet可以使用這台iSCSI伺服器



當Extent跟Target均設定完成後,記得要打勾右上角的"Enable"後點"Save and Restart"套用!不過要注意使用iSCSI的話你的"舊"電腦必須至少要有256MB的RAM或以上~



到目前為止FreeNAS上iSCSI的設定都已完成,接下來就可以開始試看看把那台Vista的電腦連上我們的FreeNAS iSCSI伺服器!回到之前iSCSI啟動器的那個設定畫面,上面點選"探索"後點"新增入口",然後輸入iSCSI伺服器的IP



輸入完成後從上面的"探索"切到旁邊的"目標",就會發現已出現了一個iSCSI伺服器目標,但是狀態還是在"非使用中",所以需要作"登入"的動作



點一下"登入"後狀態就會變成"已經連線",代表一切順利



現在可以打開"電腦管理",您就會發現您的電腦多了一台5G左右的不明磁碟,其實這就是iSCSI連上的那個5G的target,現在已變成好像本機的一台硬碟了~



想用這顆虛擬硬碟,我們必須要先用滑鼠右鍵點一下"不明磁碟1",再點一下"初始化磁碟"進行初始化



完成初始化後這顆5G的"硬碟"就可以使用了~ 筆者把它設為Z:



它就像一台本機的磁碟機一樣,也可以進行重組



也可以自由設定相關的windows權限~



在"裝置管理員"中也可以看到這顆磁碟機,弄得好像跟真的一樣~



不過事實上這個硬碟是由FreeNAS上一個檔案(extent0)所模擬出來的~



接下來我們就試試看iSCSI的表現,傳一個大檔到Z:上,由於筆者的舊電腦(FreeNAS)是在用一張100Mbps的網卡,所以極速會被限在100Mbps(12.5MB/s)上。而FreeNAS上CPU的使用率的確也比使用SAMBA時高,現在平均約為50%



傳大檔一般是測極速用,測又多又密的小檔時效能可能就會掉很多了~ 現在來看看以Block Level來運作會不會受到多大的影響?果然,複製11307個檔案上去(約98MB),平均的速度就只剩1MB/s左右了!不過相對的,CPU使用率也降低很多~



覺 得iSCSI在傳送小檔的表現慢很多嗎 ?其實這算還好,請大家再看看複製相同的東西時SAMBA的表現~ iSCSI一分多鐘就傳完的東西,SAMBA要花上十幾分鐘才有機會傳完,平均速度只有220KB/s,而且網路如果有一點點不穩,很可能會傳到一半就死 掉~ 這也是SAMBA多年來為人詬病的地方!(大家如果有經驗透過VPN來使用SAMBA或"網路上的芳鄰"來傳東西就知道了,通常都是到一半就傳送失敗)



相信現在大家對iSCSI的優點都已有目共睹了,有興趣的話也可以自己裝一台FreeNAS來玩玩,相信如果換成Giga網路的話會更"刺激"~

接下來,我們將對FreeNAS架站及BT下載這2個功能進行簡單的介紹~


看完上一篇 (打造免費的全能型NAS - iSCSI攻略) 這個企業級應用的iSCSI功能後,現在我再回來看看一些比較普通又比較多人想要的功能!沒錯,就是Web Server(網頁伺服器)及BT下載,這2個功能目前是沒有被FreeNAS強調,可能還在Beta的階段吧。另外FreeNAS上的網頁伺服器不是使 用我們常聽到的Apache,而是使用另一套更輕巧的lighttpd,雖然有支持PHP但還是沒有辦法直接架一些動態的網站,像討論區等等,因為目前 FreeNAS中沒有內建任何的資料庫(Database),像最常用的MySQL並沒有內建在內(但是相信高手應該有辦法自行把MySQL安裝到 FreeNAS上),所以沒有辦法架一些PHP+MySQL的網站,不過還是可以寫些php的小程式或其他不會用到資料庫的網站,或成為一個HTTP下載 中心也不錯,讓別人把FTP上或其它存在FreeNAS中的檔案透過HTTP的方式下載,方便又實用!

要啟用FreeNAS的網頁伺服 器,點Service -> Webserver,因為FreeNAS的網頁管理介面(WebGUI)已用掉標準的HTTP 80 PORT,所以這邊需要再另外指定一個PORT給Web Server(如88PORT),或您也可以把FreeNAS的網頁管理介面的PORT從80換成別的,這邊就可以使用80 PORT了!最後設定完別忘了要把右上角的"Enable"打勾,再點"Save and Restart"便可~



這邊是上一步提到,把FreeNAS的網頁管理介面的PORT從80換成別的PORT的方法,進入System -> General Setup後把圖中紅框原本的PORT 80改成別的PORT即可



為了驗證FreeNAS的Web Server可以正常跑HTML跟PHP,我們就在Web Server的資料夾中放上2個檔案,一個HTML,一個PHP,看看是否都可以被正常執行



結果HTTP的檔案可以正常透過瀏覽器顯示



PHP也可以正常透過瀏覽器正常執行並顯示結果,並發現原來這版FreeNAS上跑的PHP版本為V5.2.6



當然,有用Web Server的使用者通常都習慣以FTP來上傳網站的檔案及資料,那FreeNAS的FTP又有哪些功能呢?現在來簡單的看一下~



有支援FXP(雖然不安全,但是可以把資料從一個FTP站直接搬到另一個FTP站,這卻是十分的方便),另外FTP的安全性方面也支援SSL/TLS加密法,只是憑證的部份要自己產生,有點麻煩 >.<



最後也算是萬眾矚目的一個功能,BT下載~現在市面上大部份的NAS都已內功這個功能,就算是沒有支援,也有一堆高手針對Linux的機種提供自己DIY加裝BT的方法。
要 啟用FreeNAS上的BT功能,可以進入"Services" -> "BitTorrent",把一些基本的東西設定好後,把"Enable"打勾後點"Save and Restart"便大功告成! 但是要注意BT下載的GUI跟FreeNAS是分開的,它的預設網址是http://"您FreeNAS的IP":9091



進入BT的GUI後發現還蠻單純的~



聽說有支援BT的DHT網路,也有支援BT加密的協定



加入了一個中文的torrent後,居然看到亂碼...不過老實說...這也在預期之內,FreeNAS才加入BT的功能沒多久,不太可能一次就十分完善吧~



結果再多加入一個中文torrent後,發現原來不是完全不支援中文的torrent,而是部份有問題,部份又可以正常顯示~ 不過老實說,這對下載是完全沒有影響!點一下右上角的"Inspector"還可以看到torrent的一些資訊



也可以看到目前進度的詳細資料~



最後,就是下載速度的部份,個人覺是一般一般,不過要認真比較的話得在同一個ISP下,同時再開一台電腦來下載同樣的torrents,這樣比較起來才會比較有意義!


不過如果是組一台Intel ATOM的小電腦裝FreeNAS來當動物機(雖然目前還沒有支援eMule...),下載比電腦慢一點也可以接受啦~ 全文完,謝謝收看!
