[MIS] 計算SubnetMask - 程式設計筆記byChris- 點部落

[MIS] 計算SubnetMask

一.為何要使用subnet mask


在IPv4的協定下,IP位址是由4個8位元組成的數字來表達,如200.1.1.130。

一個IP位址分為網路位址(Network Address)+主機位址(Host Address),依網路位址所佔的位元數不同而分為A/B/C/D級網路。

IP數字的0及255是預設的主機及廣播位址無法使用,所以每個數字可用的IP位址變化只有254個(256-2),這也就是一般C級網段的Gateway IP都預設x.x.x.254的緣故。...

Noob Wireless Share v4:把Win7、Win8當成無線基地台來分享網路 | Noob's Space

當你需要分享無線網路、身邊剛好又沒有基地台怎麼辦?這時候本來就帶有 Wi-Fi 存取功能的筆電就派上用場了。用筆電充當基地台,其實並不新奇,早在 XP 時代就能透過 Ad Hoc 的方式來建立多台電腦之間的點對點網路,不但能夠分享網路訊號、也讓無線對傳資料更方便。不過要用什麼方法來分享網路呢? 也許有人會想到要用 Connectify 來分享,不過有些電腦裝上 Connectify 卻有許多問題,或是像之前的Bug。也許也有人會想到要用 netsh 指令來分享網路,不過也有人不習慣命令提示字元那黑底白字的視窗。 這時,本文的 Noob Wireless Share 就可以解決問題啦。

Windows 8筆記型電腦設定為無線基地台

家中或工作場所,臨時有多台筆記型電腦、平板電腦、智慧型手機等無線裝置需要上網,卻沒有無線基地台或無線IP分享器可用,怎麼辦呢?沒關係!只要有一台筆記型電腦,加上一個可連上Internet的有線網路,利用Windows 8內建的功能,只要幾個步驟,就能夠將安裝Windows 8的筆記型電腦設定為無線基地台,提供給其他無線裝置使用,詳細的做法說明如下:〈Windows 7筆電設定的方法詳見:Windows 7筆記型電腦設定為無線基地台http://blog.xuite.net/yh96301/blog/69378815-Windows+8筆記型電腦設定為無線基地台

大台北美食推薦懶人包(置頂並持續更新,上次更新日期為2013年8月)
鑑於時常有人詢問我什麼東西要去哪裡吃,或什麼樣的聚餐得去哪邊吃,乾脆我用一篇來寫下我在台北所推薦的食物,方便大家搜尋。

再次的強調美食是很主觀的,合我胃口的食物不一定會合你/妳的胃口,而我會隨著寫過的店家來持續更新這個懶人包。

另外,以食物分類區內的店家有可能是推薦但不是最推薦的,意思是可能我吃過更棒的,但只是最近還沒去過並貼出來。

最後,我記錄的是當時去用餐的體驗。如果隔了一陣子去,餐廳有進步或退步,這並非我能掌控。

剛學物件導向程式設計的人常常把Overriding與Overloading兩個詞搞混,不僅是因為這兩個單字看起來很像,連使用方式都很類似。於是愛用國貨的中文書市場為了造福國內廣大英文辨識力不良族群,推出了以下絕妙的通俗翻譯:
  • Overloading=多載。

Outlook express 收件匣爆掉而無法收信 - NCUCCWiki

Outlook express 收件匣爆掉而無法收信 - NCUCCWiki:


解決方法

重建outlook express的index

執行前確認工作:
這個方法主要用在修復 outlook express 的 index, 也就是如果你的收件匣其實只有 50封信(你預估只會佔 100M), 但是實際郤佔了1G 以上的空間時, 表示你的 index 已經亂了, 需要修復, 請依照下列的方法執行, 當重新匯入時, 就會重新 index
基本上每一個資料匣都不能超過 2G , 常出問題的包括收件匣及寄件備份
開啟outlook express,如果信件還在,請把信件依年度或依人分類移動到不同的資料匣中。(此時,寄件備份也要整理,同時設定不要「每幾分自動收信」 , 不要「進入outlook express,就馬上收信」。)離開 outlook express,去檔案總管看file size,如果即使已經完成上述動作,file size仍然很大,表示必須重建index。

超大 PST 和 OST 檔案的剪裁工具:
當您啟動 Microsoft Outlook 或嘗試開啟個人資料夾 (.pst) 檔案或離線資料夾 (.ost) 檔案時,可能會收到下列錯誤訊息:
在檔案  中找到錯誤。請關閉所有具有郵件功能的應用程式,然後再使用電子郵件信箱修復工具更正錯誤。
其中  是 .pst 檔案的路徑。

即使執行了「電子郵件信箱修復工具」(Scanpst.exe),該檔案的問題還是無法解決。

SSL/TLS Strong Encryption: FAQ

SSL/TLS Strong Encryption: FAQ
How can I get rid of the pass-phrase dialog at Apache startup time?
The reason this dialog pops up at startup and every re-start is that the RSA private key inside your server.key file is stored in encrypted format for security reasons. The pass-phrase is needed decrypt this file, so it can be read and parsed. Removing the pass-phrase removes a layer of security from your server - proceed with caution!

Remove the encryption from the RSA private key (while keeping a backup copy of the original file):

$ cp server.key server.key.org
$ openssl rsa -in server.key.org -out server.key


Make sure the server.key file is only readable by root:

$ chmod 400 server.key


Now server.key contains an unencrypted copy of the key. If you point your server at this file, it will not prompt you for a pass-phrase. HOWEVER, if anyone gets this key they will be able to impersonate you on the net. PLEASE make sure that the permissions on this file are such that only root or the web server user can read it (preferably get your web server to start as root but run as another user, and have the key readable only by root).

As an alternative approach you can use the ``SSLPassPhraseDialog exec:/path/to/program'' facility. Bear in mind that this is neither more nor less secure, of course.

It also develops, maintains, and makes available at no cost, the largest collection of research documents about various aspects of information security, and it operates the Internet's early warning system - Internet Storm Center. The SANS (SysAdmin, Audit, Network, Security) Institute was established in 1989 as a cooperative research and education organization. Its programs now reach more than 165,000 security professionals, auditors, system administrators, network administrators, chief information security officers, and CIOs who share the lessons they are learning and jointly find solutions to the challenges they face. At the heart of SANS are the many security practitioners in government agencies, corporations, and universities around the world who invest hundreds of hours each year in research and teaching to help the entire information security community.
