• How to run Hyper-V Virtual Machine Management Service using a domain account

  - by Selhoum

  I have an Domain account with admin priviliges and I need to use that account to run the Hyper-v Machine Management Service. my goal is to use that domain account to create VMs using ISO files that are in a different server within the same domain. I was told that if I use the local account to do this things may not work. How do I run the Hyper-V Virtual Machine Management Service under a domain account?

• How to wipe free disk space in Linux?

  - by Alex B

  When a file is deleted, its contents may still be left in the filesystem, unless explicitly overwritten with something else. "wipe" can securely erase files, but does not seem to allow erasing free disk space not used by any files. What should I use to achieve this?

• WINAPI window management question

  - by gekod

  I'm learning to develop windows applications using WINAPI and plain C. Now I got a bit confused with all those handles and would like to ask if you guys could teach me some good practices to structure and handle controls and windows. Here's where I get confused: Using the IDs declared in the resources for each object, we can get their handles using GetDlgItem(). Now what if we don't know their parent, which is needed by this function. One example: We have the main window created at launch. Then we register two new window classes and create a window for each new class and we create a message function for each too. Now if inside one of the children windows I create a button and inside the other child window I create a text label. Now when we click the button inside of child window A the label in child window B shall be modified to whatever. The WM_COMMAND for the button is interpreted inside the message loop for child window A. Now what would be the best and more elegant way to access the text label inside the child window B? I am in the process of learning the WINAPI and just want to learn it right from the start instead of producing Hacked code that someday becomes unreadable and to later have to adapt to a new way of programing.

• Recovering damaged external hard disk by installing internally

  - by nfarshchi

  I had a 1TB Western Digital (My book series) 3.5" USB3. One day, the SATA to USB3 converter board was damaged and has not worked since. I decided to open the cover and use the HDD as an internal HDD. When I attached the HDD to my PC and booted up in Windows, it asked me which type of ????? I want to use "MBR or GBR" (I dont remember the exact question) I chose MBR and Windows gave me a 1TB empty Hard drive. I tried to recover with recover my files and some other recovery programs but no success. Some one told me that you should choosed GBR instead of MBR . How can I do that now? Another guy told me that the SATA to USB3 converter board is coded to save data on HDD and you can not use them internally without losing data, and I should find another SATA to USB3 board (exact same). It is impossible to find because they are not produced any more. Please help me to find a solution to bring back my data. UPDATE I have 1TB WD "Mybook" USB 3. the board that convert sata to usb3 was damaged. so when the HDD was in the box computer did not recognize it. I opened the box and remove HDD to use it internal. after connecting to my PC windows showed me one massage that I had two choice MBR or GPT I choosed MBR one and windows gave me 1TB empty new volume. I tried many recovery software to recover my data but no success. I brought it to one expert recovery company and they told me the converter board (SATA to USB3) make some encryption on data and with out that board you cannot recover any thing. so I bought another empty WD box and put the HDD inside but even after that also there is no file. I tried to recover again in this state but no success. so I have some unanswered question. does this converted boards make any password or encryption? if yes how can I solve it? does using many recovery programs affected my data? any suggestion or solution for bring back my data? I had use recovery programs such as : recover my files , EaseUS data recovery, easy recovery, test disk, Ontrack easy recovery . Note: when I was using test disk it asked me to choose which partition table I want to use. as it was I choose NTFS, does this made any change on data?

• CLI Shared Hosting Management (scripts to manage web users and hosts) [on hold]

  - by aularon

  I am currently administrating two servers: first one has no control panel, I am creating directory structure, setting permission, configuring different aspects (users/php-fpm pools, nginx hosts..) for each of sites. With more clients, I sat up ISPConfig on my second server, everything is easily handled by ISPConfig Web Interface. However, I am searching for a CLI based solution, i.e. a set of scripts to create and manage hosts. Basically, a method to control ISPConfig from the command line (so I can use it over SSH) would be a good start. Does anybody know of such effort? I searched but all I got was web based solutions. Thanks.

  Now that I can turn off the annoying Reload popups, I would like a quick way to manually reload the file I am working on in NotePad++ via the keyboard. Looking at the File menu, Reload from Disk does not have a shortcut. Is there a hidden shortcut that you know of or someway to map one built-in?

• External Hard Drive Won't Mount - MAC OSX

  - by dtj

  I have a Western Digital hard drive that's about 4 or 5 years old. It's 500 GB, USB. I use it to backup my Mac every so often. I had it partitioned: 1 side for full backups, and the other side for general storage of music, installers, etc. I decided to get rid of the partition today and dump all the data. So I opened disk utility, and hit 'erase'. It started thinking and then disk utility crashed. After the crash, the hard drive won't mount, however disk utility still sees the drive, but not the individual volume within. I tried booting up Disk Warrior and no luck there either. It has the drive as an "unknown drive". When I hit rebuild, it goes through all it steps and then stops cause of this error: The drive "unknown" is severely damaged and DiskWarrior is unable to determine its case sensitivity What can I do at this point? There isn't any physical damage to the drive. Never been dropped or anything.

• Server hang - data loss on reboot, post mortem analysis

  - by rovangju

  A development server I'm responsible for (ext3 on raid 5 w/Debian Squeeze) froze up over the weekend and I was forced to reset it, as in unresponsive from KVM/physical keyboard access, no eth devices responding, etc. Not even the backup process ran (Figures, the one time I don't check for confirmation) So after the reset, it turns out that every trace of disk IO activity that should have happened for a period of ~24H is completely gone. The log files have a big gap in the dates and times. As if the writes were never committed to disk, no processes seemed to have run. Luckily it was a weekend and nothing of value would have been lost and I don't suspect a hack. What can I do in post mortem to this event - to prevent it from ever happening again? I've seen this happen before on a completely different machine running FreeBSD. I am rounding up the disk checking tools right now - but there must be more going on! Mount options: /dev/sda1 on / type ext3 (rw,errors=remount-ro) Kernel: Linux dev 2.6.32-5-686-bigmem Disk/Inodes: 13%/3%

• Migrating from one linux install to another: How to keep the second disk around?

  - by Jim Miller

  I've got a linux box running Fedora 19 that I want to move to CentOS 6.4. Rather than trying to do something fancy with the current disk (which has also accumulated a lot of sludge over the years), I'm going to get a new disk, put CentOS on that, and then move the to-be-preserved bits of stuff from the old disk to the new one. I haven't done this yet, but I presume it should be semi-straightforward -- do the CentOS install on the new disk, mount the old disk on /olddisk or somesuch, and start copying. However, I'm not sure how to handle getting the machine to recognize the new empty disk as the target of the CentOS install (I suppose I can just pull the old disk during the installation), remember that this is the intended boot disk once the install has happened), and tweak /etc/fstab (right?) to set up the old disk on the desired mount point. (Both disks are, or will be, SATA.) I could probably hack it together without losing too much hair or doing too much damage, but could anyone offer some advice that would get/keep me on the right track? Thanks!

• Would a PHP application benefit from being served from a RAM drive?

  - by Tom Marthenal

  I am in charge of hosting a PHP application that is large and slow, but easy to scale. The application is entirely static, with writable disk storage needed. We've profiled the application, and the main bottleneck appears to come from loading the application and not the work the application does. The application is not CPU-intensive, although it does use a fair amount of memory (think Magento). Currently we distribute it by having a series of servers with the same PHP files on their hard drive and a load balancer in front of them. Easy but expensive. I've been reading about RAM disks and the IO benefits they offer, and was wondering if they would be well-suited to PHP applications. Since PHP applications are loaded from disk for every request and often involve lots of different files (as opposed to being kept in memory like with a Java application), I would figure that disk performance can be a severe bottleneck. Would placing the PHP files on a RAM disk and using the mount point as Apache's document root offer performance benefits? A startup script could create the RAM drive and then copy the files (which are plain-text and small) from a permanent location to the temporary RAM drive. Does this make sense, or should I just trust the linux kernel to cache the appropriate files in memory by itself?

• Take a regular Windows 7 clone with clonezilla (device-to-image)

  - by Mario De Schaepmeester

  I am unexperienced with cloning software and I've decided to use Clonezilla as it seemed best as freeware. I chose device image and left most options standard. I chose expert mode anyway to see what I could configure, and decided to try the lzop algorithm instead of the default one for compression. The rest was left at default. When Clonezilla asked me which partitions to clone (I chose parts to image), I chose the C:\ drive but Windows 7 also creates a 100MB partition on setup for system files (the actual boot partition?). I copied that into the image as well. The reason I didn't choose disk to image is that I also have a data partition that needs to stay intact. Now I'm simply not sure that this is the way to go, should I ever need to restore my disk image. Will Clonezilla know what to do with both partitions and will Windows 7 work perfectly after restoring? Edit: apparantly a similar question has been asked before. The link to the first article in the answer is not relevant to me since it covers a device-to-device clone. It appears the windows installation disk can repair the 100MB partition. As for Clonezilla, it copies "hidden data after the MBR" by default too. I don't know, I feel I'll be allright whether by restoring the partition with Clonezilla or repairing it with the Windows 7 disk.

• Monitoring disk performance with MRTG

  - by Ghostrider

  I use MRTG to monitor vital stats on my servers like disk space, CPU load, memory usage, temperatures etc. It all works fine and well for parameters that don't change rapidly. By running small VB script I can also get any Performance Counter. However these scripts are called by MRTG every 5 minutes while performance counters like physical disk idle time return a snapshot value from previous few seconds so a lot or data is missed. Surely I could write a service that would poll all required counters in background and store average values somewhere on disk where MRTG would pick them up. However before I do so I would like to find out if there is some ready solution that would allow me to get average value of some counter for the last 5 minutes as opposed to immediate snapshot.

• SATA hard disk for laptop on Desktop PC

  - by Lawliet

  I know that this forum is for programming-related questions only, but I'm having this dilemma so here I go. Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected? I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V) Thanks in advance
