Moving My Desktop on to the Cloud

By admin, August 13, 2011 11:00 pm

I have been planning to move my desktop on to the cloud for years, now it’s the right time as cloud technology has finally matured.

There has always been a need for me to print documents via Remote Desktop on my locally attached laser printer. Today, I finally got time to try this out, I thought it was as simple as enabling the Printer in Local Resources under Remote Desktop options, but it turns out no printer was found in the RDP session PC. In additional, Windows 7 or W2K8 doesn’t have this problem as printer drivers were loaded by default, only Windows XP or W2K3 needs to install printer drivers.

After Google a bit, I was able to locate the answer that all you need is to install the printer driver on the remote PC as well. Soon after I’ve done that, the remote printer showed up magically. Besides, I was also able to tested out the local drive letters and USB disks on demand, they all worked flawlessly, so no need to use VPN and Shared Folder function any more. Worried about RDP’s security? It’s encrypted, if you need much higher level, then use Windows 7 or Windows Server 2008 R2 will do the trick.

Now it’s time for me to Acronis my 13 years old desktop (Dual PIII 850Mhz,1GB Ram and 120GB IDE, amazingly it’s still running and can play HD MKV!) and send it to the cloud by using vCenter Converter, then I can connect with any thin client (e.g., iPhone) as long as it has Remote Desktop, I can finally open my huge Excel way faster now! Yeah!

DDOS Attack Brought Down HK Stock Exchange Web Site to Its Knees

By admin, August 12, 2011 5:27 pm

It shouldn’t be classified as hack-in incidence at all, as the hacker didn’t break into their system but rather jammed HKSE’s pipe. Btw, no body dares to say the truth that there is no way to prevent bandwidth type of DDOS attack, as bandwidth is limited, but DDOS bot is unlimited, so even the biggest gun will be brought down to its knee including FBI site last year. That’s why HKSE senior is so afraid to disclosure the bandwidth they had.

and Guess Who’s that security expert in DDOS from Iseral? Well, there is only one, my guess is Radware!

【明報專訊】本報獲悉,前日令港交所「披露易」網站癱瘓導致7隻股票停牌、連累股民帳面損失逾2000萬元的海外黑客攻擊,相信源自中國大陸、韓國、印度及俄羅斯等多國數以百計的「傀儡電腦」,但警方仍未確認誰是幕後主腦。而黑客昨日再度攻擊披露易網站,但因港交所按警方建議及時加裝「過濾裝置」,成功阻截攻擊。為防再遭黑客癱瘓網站引發停牌,港交所引入5項新措施。

分散披露通告 業績名單登報

港交所行政總裁李小加指出,今日起會引入的5項新措施,包括把上市公司通告由過往的中央(披露易)發放,改為分散披露,增加黑客攻擊的困難。港交所亦會每日以報刊廣告及電郵等形式,把公布板的上市公司消息告知小投資者及證券商(詳見圖)。

李小加昨日又證實,黑客是以「分散式阻截服務攻擊(DDoS)」癱瘓披露易,電腦專家指這種襲擊很難追查出誰是幕後黑客(見另稿),但建議港交所日後多做「滲透式」測試,即以黑客角色嘗試攻擊自己網站,以找出保安漏洞。

警或聯同國際刑警緝兇

警方商業罪案調查科科技罪案組則指出,前日接獲港交所舉報指披露易網站被干擾,以及介入調查後,已把案件列作「有犯罪或不誠實意圖而取用電腦(此罪最多可判監5年)」處理,暫時未有人被捕;據悉,警方不排除會聯絡國際刑警追查幕後黑客主腦。

李小加則再以為免影響警方調查為由,未肯披露黑客來自哪些海外國家,並強調事前未接過恐嚇。但本報獲悉,前日一浪接一浪的黑客攻擊,是來自中國大陸、韓國、俄羅斯、印度等多國至少數以百計的傀儡電腦,由於攻擊頻率高兼技巧多變,料是高級黑客所為,警方前晚遂已即時建議港交所加裝過濾裝置,阻截攻擊,結果獲接納,並由港交所聘用的供應商,包括以色列專家在內人員,成功於前晚裝好過濾裝置,故黑客昨日再襲擊披露易網站時,網站未有癱瘓,只是一度反應遲鈍。

股民促賠償 李小加稱停牌正確

披露易癱瘓,令7公司股票(港交所、匯控、國泰、中國電力、華潤微電子、大新銀行及大新金融)及419隻衍生工具前日停牌半天,料令大批原看好的投資者昨蒙受損失,不少人怒吼指港交所應賠償。李小加昨就會否賠償一事未有正面回應,只是強調對部分投資者因不能買賣股票而損失感到遺憾,又形容要7隻股票停牌是「痛苦決定」,但兩害取其輕下,堅持停牌是正確決定,因為不能讓小投資者在得不到公平資訊情下買賣股票。

對於有激動股民認為他應該辭職,李小加不以為然,他表示,「若做錯了當然要負責……(但停牌)已是最好的選擇」,他強調決定是具有良好目的(in good faith),並強調港交所關鍵的清算及交易系統,採高保安封閉式運作,未有受黑客攻擊。

海外黑客前日癱瘓了港交所「披露易」網站,所發動的「分散式阻截服務攻擊(DDoS, distributed denial of service attack)」攻擊法,即是在背後發出遙控指令,令全球數以百計已中電腦病毒的傀儡電腦,同時向目標網站發出大量攻擊信息,耗盡其頻寬及伺服器能力使之癱瘓,事件揭出披露易網站事發前欠缺強力保安設施,無法抵擋黑客攻擊。

昨設過濾裝置 成功擋襲擊

港交所指出,前晚被黑客攻擊後,專家引入新的過濾裝置,成功擋住黑客另一輪攻擊,即過濾掉攻擊信息。

港交所首席科技總監周騰彪昨解釋事故時,否認披露易網站不設防,因為該網站以往曾成功擋住一些簡單的黑客攻擊。但他承認,前日海外黑客發動的DDoS攻擊,技巧遠較以往成熟兼變化多,並透過百計電腦,以極高頻率發出大量攻擊信息,終癱瘓網站。對於事發後要大半天才能令披露易恢復正常,他解釋是因專家也需時分析大量攻擊信息,才能引入適用的過濾機制抵擋襲擊。

周騰彪以為免被黑客掌握虛實為由,拒透露披露易網站頻寬有多少,但港交所會檢討是否需增加頻寬,加強抵擋DDoS攻擊,為工程人員爭取時間作防禦。

電腦保安事故協調中心古煒德稱,DDoS特色是執法者極難追查背後發動攻擊者,以往黑客曾用此法攻擊微軟、阿馬遜等國際網站以示不滿,故古氏不排除今次黑客施襲,亦可能是為宣泄對港交所或一些上市公司的不滿。

今天突然發現1987年的Aston Martin V8 Vantage前臉竟然跟1967年的Mustang Shelby GT350有八分相似。難道80年代的馬丁英倫設計師也受到了60年代的美國肌肉所影響﹖實在奇妙﹗

越來越喜歡經典跑車了﹐今天在超市的雜誌架前看了許久﹐剛巧鄰居朋友經過叫我才知道原來時間已不早了﹐這才依依不舍地離開了那堆Classic Car雜誌。

Equallogic Bad Disk Kills All Your VMs and Stay Un-Alert!

By admin, August 6, 2011 9:27 pm

I noticed both the latest Equallogic firmware v5.05/v5.07 STILL contains a bug that a failed disk won’t be indicated in group manager. What’s worst is that soon you will discover all your VM starts to BSOD/Panic and thinking it’s either related to your switch/VMWare/ESX Host, until you found out  it is actually caused by Equallogic firmware. This bug causes volume corruption and excessive disk latency, killing all your VMs at the end, both scenarios have been preciously reported by actual EQL users in VMTN.

This is VERY SERIOUS! Users who bought Equallogic supposed to have a 99.999% reliability (what they called Five 9s), but a fail disk won’t show up in the error windows nor it flashes the amber light to alert you is a very scary experience and plain stupid!

I read from VMTN that a bad luck EQL users has no way to find out which drive has failed, finally he asked EQL support to WebEx into his console, spent hours to figure out the one.

Simply NOT ACCEPTABLE for this kind of high-end SAN!

Yes, that’s why I am still holding off my upgrade to v5.0.7 (currently at v5.0.2), I was told once by Dell consultant this: “DON’T UPGRADE ANY OF YOUR FIRMWARE if you are not having any problem.” I guess he meant for something by then, now I fully understood!

VMware Finally Revised the License Under Heavy Pressure!

By admin, August 4, 2011 10:34 am

After the heavy 99.9% negative comments in VMTN, VMW finally surrendered sort of! Why did you do that in the first place? Stupid $$$ driven decision! You have hurt many loyal followers heart deeply this time. Now I finally see why Monopoly is a bad thing!

Finally ESXi Free Edition is able to use 32GB compares to 8GB previously and I also found VSSP actually encourages use of the reserved ram model that allows memory over-commitment, but isn’t that contradict to what vRam model is used for enterprise? Seem VMware has confused everyone including itself.

As you are probably aware, when VMware announced our new Cloud Infrastructure Suite, we also introduced changes to the vSphere licensing based on a consumption and value-based model rather than on physical components and capacity.

While we believe this model is the right long-term strategy as we move into the cloud-computing era, the announcement generated a great deal of passionate feedback from partners and customers that led us to examine the impact of the new licensing model on every possible use case and scenario – and equally importantly, taking into consideration our partners’ and customers’ desire to broadly standardize on VMware. We’ve listened to your ideas and advice, and we are taking action with the following three updates to the vSphere 5 licensing model:

•We’ve increased vRAM entitlements for all vSphere editions, including the doubling of the entitlements for vSphere Enterprise and Enterprise Plus. Below is a comparison of the previously announced and the new vSphere 5 vRAM entitlements per vSphere edition:

1

•We’ve capped the amount of vRAM we count in any given VM, so that no VM, not even the “monster” 1TB vRAM VM, would cost more than one vSphere Enterprise Plus license. This change also aligns with our goal to make vSphere 5 the best platform for running Tier 1 applications.

•We’ve adjusted our model to be much more flexible around transient workloads, and short-term spikes that are typical in test & development environments for example. We will now calculate a 12-month average of consumed vRAM to rather than tracking the high water mark of vRAM.

Finally, we introduced the vSphere Desktop Edition to address vSphere licensing in a desktop environment. vSphere Desktop is licensed on the total number of Powered On Desktop Virtual Machines allowing  customers to purchase vSphere for VDI use case on per user basis.  Our price books are being updated and will be available on Partner Central shortly.

Update Sep-14

There is an interesting article about how enterprises in Taiwan responded to the vRam change, it seemed 99% are still against the change.

Hot-add: A Different Term in Veeam B&R

By admin, August 4, 2011 9:06 am

I always wonder what Hot-add means in Veeam’s term as it’s always mentioned in their forum, now I understand after reading the blog post, but again I never use virtual appliance mode as it’s for small enviornment say if you have 30 or less VM to backup.

Hot-add – This is frequently used when referring to virtual appliance mode backups within Veeam Backup & Replication. Basically, once the virtual machine backup is underway; the associated VMDK files are added dynamically to the Veeam backup server. This dynamic procedure can only happen when the virtual machine has a snapshot in place, and then the VMDK files of the source virtual machine are disconnected from the Veeam backup server once the backup steps are completed. Further, this option is only available when Veeam Backup & Replication is installed on a virtual machine. Veeam Backup & Replication has supported Hot-add mode since version 4, released in 2009.

賽道極速GT﹕法拉利 FXX EVO

By admin, August 2, 2011 3:27 pm

2005年標誌著法拉利的一個新的歷程碑﹐法拉利在推出其21世紀的新產品ENZO後的第三年﹐一台擁有幾乎跟ENZO完全一樣車身設計的加強版FXX面世了﹗其實任何擁有FXX的型號現在已經可以理解成那個車款的限量升級版。

法拉利只限量的製造了29台FXX給其指定的車主﹐簡單來說就是有錢也沒得買﹐完全是小圈子的游戲。其實後來那額外的第30台是法拉利送給車神Michael Schumacher的榮休禮物﹐記得兩年前車神以Stig的身份駕駛這他那台與眾不同的黑色#30 FXX在Top Gear節目裡榮登賽道速度首位﹗

FXX基本上採用了ENZO的很多部件﹐但主要還是引擎功能上提昇了百分之20到達了驚人的800馬力﹐另外齒輪箱也集成了很多最先進的法拉利F1技術。整台車可以說是一台跨時代的電腦與機械結合的超級GT產物﹐並且電腦把所有的賽道表現數據都給準確地紀錄了下來以提供給法拉利改良他們以後的超跑技術。要知道FXX並不允許在普通的公路上行駛﹐而是要法拉利指定的跑道和日子才能盡情兜圈﹐花那麼多的錢還要受那麼多的限制﹐而且給這麼多錢還要給別人當白老鼠﹐法拉利的洗腦功力可真不可小看﹐真不明白那些車主是怎麼想的。

FXX經過了兩年多的實地測試後﹐法拉利終于把全部29台收集得來的數据進行了詳細的分析後(很明顯老舒的數據絕對不能做準﹐所有一定要撇除)﹐推出了其終極版的FXX﹐名為FXX EVOLUZIONE﹐馬力加大到難以想像的860匹﹐最快理論值達400 km/h﹐0–100 km/h為2.5秒﹗

我一早就聽說Hotweels Super Elite的那台車神Michael Schumache的黑色#30 FXX(編號L7126)做工超群﹐但從來也沒有在本地車模店或拍賣場見過﹐當然普通Elite版(編號N2061)的也有﹐但自己始終比較喜歡沒拉花的普通街車版。今天經過車模鋪特別問老闆這台黑色的FXX EVO是否有紅色的座椅內飾﹐果然是而且又有特價﹐這下好了﹐終于可以跟我好久以前買的那台紅色EVO配對了。

最後就是關於紅色FXX EVO版本的問題﹐據我了解﹐2008年尾我收的那台FXX EVO編號是N2056﹐後來2010年再版的則變成了的T6247 ﹐看似一樣﹐其實不同﹐最大的分別是N2056 FXX Evoluzione 2007 Rosso Scuderia Elite是橙紅色的Presentation版本﹐而再版的T6247 FXX Evoluzione 2009 Rosso Corsa Elite則是一貫的法拉利紅色﹐而且是2009年版本。
