Olayı abartmamak lazım tabi:

VMware vCenter Server 6 installation low memory workaround

I was installing VMware vCenter Server 6 Update 2 with Embedded Platform Services Controller on a Windows lab server with 8GB RAM. I got the following error:

VMware vCenter Server detected 8160MB of memory. 8176MB of memory is required for the selected deployment type.

You can easily skip this error with initiating the following in command line:

VMware-vCenter-Server.exe SKIP_HARDWARE_CHECKS=1


Nilgün ve Ferhan


Ferhan : Ne var bu gülümseyişin altında?
Nilgün : Sen varsın.
Ferhan : Anlamadım?
Nilgün : Sen varsın dedim ya. Ya ben az önce evde oturuyodum, kendi kendime dedim ki çok şükür Ferhan var dedim. Çok şükür dedim.
Ferhan : Yani sırf bunu söylemek için mi geldin?
Nilgün : Değmez mi?
Ferhan : Ne münasebet. Yanında başka bir mazeretin daha olsaydı mesela manava da gidiyor olsaydın bu kadar değerli olmazdı.

the lying detective

Sherlock : Are you OK?
John : [laughs] What, am I…? No, no, I’m not OK. I’m never going to be OK. And we’ll just have to accept that. It is what it is, and what it is is… shit.
Mary : John, do better.
John : You didn’t kill Mary. Mary died saving your life. It was her choice, no-one made her do it. No-one could ever make her do anything. The point is, you did not kill her.
Sherlock : In saving my life, she conferred a value on it. It is a currency I do not know how to spend.
John : It is what it is. I’m tomorrow, six till ten. I’ll see you then.
Sherlock : Looking forward to it.
John : Yeah.

Errors in NTP Auth configuration using autokey

During latest leap second test activities, I was tinkering with my test NTP server and I encountered an error: "RAND_load_file /root/.rnd not found or empty"

There is not much help on internet. You just need to seed with the following command:
dd if=/dev/urandom of=/root/.rnd bs=512 count=1

And if you have an error: "crypto_setup: random seed file not found error:"
Add “crypto randfile /dev/urandom” entry to /etc/ntp.conf without the quotes.

about being human

Bernard : Lifelike, but not alive. Pain always exists in the mind; it’s always imagined. So what’s the difference between my pain and yours, between you and me?

Ford : This was the very question that consumed Arnold, filled him with guilt, eventually drove him mad. The answer always seemed obvious to me. There is no threshold that makes us greater than the sum of our parts, no inflection point at which we become fully alive. We can’t define consciousness because consciousness does not exist. Humans fancy that there’s something special about the way we perceive the world, and yet we live in loops, as tight and as closed as the hosts do, seldom questioning our choices, content, for the most part, to be told what to do next. No, my friend, you’re not missing anything at all.


Ford : I’ve told you, Bernard, never place your trust in us. We’re only human. Inevitably, we’ll only disappoint you. Goodbye my friend.


Felix : Are you sure you’re gonna be okay?
Maeve : Oh, Felix. You really do make a terrible human being. And I mean that as a compliment.

HP Smart Array B140i SATA RAID controller OS boot problem

Recently I installed VMware ESXi on a HP DL160 Gen9 server and couldn’t boot afterwards. After a short investigation I found out that the default configuration of the controller prevents booting. The controller should be configured and enabled to support SATA AHCI mode. Actually it is necessary to configure it for all servers carrying HP Smart Array B110i, B120i, B140i and B320i RAID controllers.

To do that:

1) In BIOS/UEFI, go into “System Options”
2) Go to SATA Controller Options -> Embedded SATA Configuration
3) Select “Enable SATA AHCI Support”

For a similar case in RedHat:

WWN / MAC Formatter

Since I first dealt with SANs and WWNs years ago, I thought there should be a more practical way to edit WWNs, most of the time to add colons between characters. I could not find an online tool to do this. One can and possibly does use a little more advanced text editor to do block editing or some custom scripting to do this task. I wanted to make it easier and also share with others so I decided to build a php tool here. With adding some features and extending the idea to MACs, this came out:

WWN/MAC Formatter

I hope it helps other system administrators.

Exporting images from headers or footers in Excel 2007 and 2010

If you don’t have the original file of an image used in a Excel file header or footer and you need it, here is a solution: All Office 2007, 2010… files are actually zipped files. If you have an older version, Excel 97-2003 (.xls), just save it as Excel 2007-2010 workbook (with extension .xlsx). Just renaming does not work. If you open .xlsx file with a program that can open .zip (7Zip, WinRAR or WinZip) you will see some folders. The files you are looking for are in folder “xl\media” and you can easily extract them from there. You may copy the file and work on the copy if you want to be on the safe side.

ölmeyen adam

“Bu hayatta herkesin bir derdi var Cemal. Benimki de bu. Ölemiyom be ..ına koyayım. Eyi bi şey sanıyon bunu demi? Herkesler öyle sanıyor ama gel bir de bana sor. En berbat tarafı ne biliyon mu? Hiç kimseden hiçbir şeyden korkun kalmıyor. Ar damarı çatlıyor adamın. Doğru ne yanlış ne her şey karışıyor kafanda. Bu ..ına koduklarımın 100 sene önce neye inandıklarını görsen çok gülersin. Ben biliyom mesela. 100 sene sonra neye inanacaklar onu da biliyo olcem. Ya her şeyleri biliyom ben Cemal. Hee her şeyleri bilmekle hiçbir şey bilmemek aynı şey. Odun gibi oluyon işte. Onun için çok fazla kurcalamicen meseleleri. Eninde sonunda ölcek olan birisinin bu dünyanın derdini çözmesine imkan yok.”
