• Windows backups to VM Esxi

  - by Martyn

  I'm very new to ESXi, so apologies if this is a silly question. I have ESXi 5.1 running running on HP Proliant Microserver with internal LUNs RAIDed with HP P410 Smart Array card. I have 2 Windows Server 2012 VMs running as Domain controllers. These are being backed-up up with GhettoVCB to a dedicated datastore hosted on LUNs on a eSata external device. I have several Windows 8 & 7 PC's connected to this domain. I want to back up these Windows PCs, via the built in backup software, ideally to the external eSata device as well. What do I need to do to have the Windows PC's see the datastore? I assume I could create a VM for FreeNas or something, or share out the datastore via one of the Windows Server 2012 VMs. Both those options seem a little bit of an over kill?

• Iptables port mapping from two PCs to one

  - by Anton

  We have 3 PCs, two of it are connected to internet (both of it have 2 NIC) PC1: eth0 - 1.0.0.1 (external IP) eth1 - 172.16.0.1 (internal IP) PC2: eth0 - 1.0.0.2 (external IP) eth1 - 172.16.0.2 (internal IP) PC3: eth0 - 172.16.0.3 (internal IP) Now we want to map port 80 from PC1 and PC2 to PC3. But there is the problem: iptables port forwarding works well from PC1 or PC2, but only in case if PC3 have PC1 or PC2 as gateway. So, question is: can we have port mapping from both PC1 and PC2 regardless of gateway settings on PC3? Thank you in advance.

• Use 2 wireless adapters to connect to 2 WIFI networks (local and internet) simultaneously?

  - by Mouad

  On my HP Compaq 6710b there's an internal WIFI network adapter. Attached to the same laptop there's also an external USB Alfa WIFI adapter. I live near campus and can pick it's WIFI signal. The problem is that when I am connected to the Internet Wifi using the internal adapter, and then connect to the home (non-internet) Wifi network's router, I lose the connection to the internet (it stays connected, but there's no actual connection). So how can I use the two adapters to connect to both networks successfully ? The router is Belkin N150 Enhanced Router Model F6D4230-4 V1 The external adapter is: ALFA AWUS 036NHR

• How to expand Raid 5 on ICH10 - Gigabyte ex58-ds4?

  - by NeverEatAlone

  I was wondering if there is a relatively simple way to expand my HD space. My setup is 4 x 640 GB drives. Motherboard has 4 ports on 1 controller and 2 ports on another controller, however they cant be joined. I would like to somehow get more store space in raid configuration. One scenario that I can see working is replacing one 640 drive for a 2TB drive. Waiting for Raid to rebuild. Rinse and repeat. However, I have no idea if I would be able to even see/access the new space. All alternatives / ideas are welcome. Thank you

• Rescue data from damaged hard disk

  - by Lexsys

  Hello. I have a 500 GB hard drive with one NTFS-partition on it. I can mount it with Ubuntu and view the contents. But when I try to copy something, I get an I/O error. Ok, I tried to make its image with dd. I/O error as soon as it starts. I have installed ddrescue, but its manual page says not to use it with drives, failing on I/O. Can I manage to get some information from this drive and how to do this?

• Windows 8: Multiple monitors with varying DPI? [closed]

  - by Sid

  Possible Duplicate: Dual monitors on Windows - How do I set a different DPI or text size on each monitor? I'm running Windows 8 on my Macbook Pro Retina (220dpi) which has an external 24" monitor (~96 dpi). In Mac OS 10.8.2, the display settings seem ok and I can actually use both displays without usability issues. I don't know what scaling settings etc it uses but it looks fine. On Windows 8, however when I boost the DPI settings to take advantage of the retina display, it blows up the display on the external monitor - text is giant sized. How can I tell Windows 8 to use the real DPI settings of each monitor? NOTE: I'm not asking for Windows 7.

• How to meet Windows 8 upgrade's 20 GB requirement on a 40 GB SSD with a 22 GB Windows 7 install?

  - by deryus

  A PC I have has Windows 7 installed on a 40 GB SSD, and I bought a Windows 8 upgrade for it. The current Windows folder on it however is 22 GB, that's after removing hibernation, turning off the pagefile and removing all extra programs/features. So even if I purge every other file and folder, the Windows folder itself takes more than half the disk. The PC also has a 1 TB HDD, but the upgrade installer didn't give me any options about choosing another drive. So, is my only option to reinstall Windows 7 on a larger drive, then proceed with the Windows 8 upgrade? Or is there anything I can remove from the Windows folder that while might be dangerous for long term usage, is fine for the few minutes I need to get Windows 8 installing?

• Trouble loading an ISO

  - by crocyson

  I've created a boot disk and ISO image with paragon. I boot up the Virtual pc with the disk in and I get to my recovery page. When I am supposed to select an ISO image? My Virtual PC doesn't acknowledge any of my physical hard drives on my host PC. I've also tried copy/paste the files into my datastore and they do not show up. I've tried the option during the set up to start with the ISO but again I am not able to browse to my external hard drive that I have stored the ISO on. VMWare will acknowledge it and say that it is connected but I can't browse to it. Am I doing something wrong? I created the back up disk and ISO image on the external with paragon.

• Access MacZFS via network from XBMC

  - by AreusAstarte

  I have a ZFS RAID (zpool with three drives) hooked up to my Mac that I want to share in my LAN so that the XBMC client on my OUYA console hooked up to the television can read the drive and use it to stream my movies and television shows onto the television set. I've searched around for a bit but so far haven't found anything that helped me with it. I know that when connecting to the Mac with SSH I can't just access the drive due to different formatting. What do I have to do so that XBMC will be able to read it? How do I share it?

• Poor disk performance with high disk capacity usage

  - by GoldenNewby

  I've heard numerous times in the web hosting industry that using "too much" disk space on a drive is bad for performance. Is this just a myth? Can someone explain why this is an issue, even in a situation where the amount of IO done to the drive would be the same at 10% as it would be at 90%? I'm especially curious in the case of virtual servers. If I set up 10 Logical volumes as the virtual disks for some VMs, is it going to run better if I "waste" 20% of the disk space?

• DELL U2410 Monitor(Display Port) & Graphic card

  - by Anj

  I was looking for a 24" monitor and bought the Dell 24" inch ultra sharp monitor which has DisplayPort( new keyword for me) seems it is equivalent to HDMI. Now I would like to enhance the display capabilities for my laptop and desktop(both have VGA output as of now). Couple of questions in mind: Is there a single HD graphic card which i could use for both desktop and laptop? I understand it has to be external but if its costly then I would stick on internal graphic card for my desktop. Please recommend external if its cost effective else I would go for internal one(Budget is around $70 or Rs 4000. Is there a HD card which I could use for both HD video and 5.1 channel audio output? I generally use the computer for office work/ listening music and watching movies, not gaming.

• Files with illegal filenames [closed]

  - by Josh

  Possible Duplicate: How to force Windows XP to rename a file with a special character? I have a few files whose names have characters such as "?" and ":" that are forbidden by windows. I'm not sure how they managed to get there with these names, since I can't manually create files with these names. They're recovered from an HFS drive, but the tool that recovered them was running under windows and so should have been subject to the same restrictions while creating them, I would think. Anyway... now that they're here, I can open them, but I can't move, copy, rename, or delete them. I want to delete a few of them, but most I want to save and copy to another drive. How might I go about this?

• How do I delete Windows.old in Windows 7?

  - by CRK

  I used to run Windows 7 32 bit, but installed the 64 bit version because of a RAM upgrade. During the installation I got this message: The partition you selected might contain files from a previous Windows installation. If it does, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will not be able to use your previous version of Windows. The C:\ drive now has two (2) Windows folders: Windows (15.3 GB) Windows.old (15.7 GB) Don't see why I need the Windows.old taking over 15GB of space on my hard drive so I tried to delete it. It didn't work. How can I safely delete this folder?

• Can I Store MediaWiki Files on the cloud?

  - by user219048

  I recently got a chromebook, and I've been brainstorming different ways to put mediawiki on it (with localhost, not a server). One way I've read about online is to go into developer mode to download and set up LAMP. I was wondering, wouldn't I be able to store the apache, mysql, php, and mediawiki files on the cloud (google drive)? And if so, would anything prevent me from accessing my wiki on any other computer's localhost, assuming I could just log into Google Drive to access these files? Might there be any reduced performance when operating from the cloud?

• How do I open a program via the command prompt in Windows 8?

  - by Ahmadul Hoq

  Suppose I have a program named any_program.exe and my operating system drive is C:. The location of the program is D:\Any_Folder\any_program.exe How do I start/execute that program via command prompt in Windows 8? I have tried the command line START any_program.exe, but it shows me an error that Windows cannot find 'any_program.exe'. Make sure you typed the name correctly, and then try again. By the way, it worked perfectly in Windows 7. And, if I type START notepad.exe or START firefox.exe (Firefox is not installed in C: drive), it works in Windows 8.

• USB 3.0 hub; what can it power?

  - by pouzzler

  I own an Asus UX31A laptop, equipped with 2 USB 3.0 ports. I would like to connect several USB devices to one of these ports, using a USB 3.0 hub. 1) Am I correct in assuming the Asus "USB Charger+" commercial blurb corresponds to the USB 3.0 standard "Battery Charging Specification 1.2", and furthermore inferring that the laptop can deliver 1.5A through a USB port? 2) Does a powered external USB 3.0 hard drive draw on the USB power lines? 3) I would like to connect the aforementionned drive, an android phone, and a 200mA rated optical mouse to an unpowered USB 3.0 hub, itself plugged into the laptop. Should my above assumptions be false, would this setup be able to power all three devices? Thanks to the usb guru who'll settle my fears to rest. Best regards, Sébastien

• make a folder/partition on one computer appear as a mass storage device to another?

  - by user137560

  Is there anyway to make a folder or a partition on a computer (Linux or Windows) act like a mass storage device to other computers or devices when connected with a Male-Male USB cable? For example, I have a Windows 7 computer with 2 partitions, C and D. I would then connect that computer to another computer or a Smart TV using a Male-Male USB cable, and the other computer or device recognizes a folder/partition on current computer as a mass storage device. Is this possible? If not, is there any USB switch that can connect an external hard drive or flash drive to both a computer and TV without the need to manually switch them? (I know about some USB switches, but they only support automatic switching with some certain types of printers, not with mass storage)

• Creating image of NTFS partition in Ubuntu

  - by Pappai

  Hi, I have a system that has to be formatted often because of the specific use of it (Use it in internet cafe). I have to install the drivers and apps each time. That is a time consuming and cumbersom task for me. I want to install windows, drivers, apps etc. once and create a backup of the entire C:\ drive, and keep it in a linux partition so that I can restore the OS with all the apps & drivers ready to go! I have ubuntu live CD with me and I have created a linux partition (ext4) in the HDD. My question is: How can I create an image of the C:\ drive (ntfs disk) in Ubuntu and store it in the linux partition?

• Resize a new database to predicted maximum size

  - by John Oxley

  Currently I have a SQL Server database which is about 2 Gb. I know over the next year it's going to grow to a maximum of about 10Gb. Hard drive space is not an issue in the slightest. Is there a down side to resizing the datafile to 20Gb now, then defragmenting the hard drive? Should I resize the log file to 1Gb as well? Something ridiculously large so that fragmentation doesn't happen there either. With this question I would like to avoid the datafile becoming fragmented on the disk itself, but I don't want to negatively impact performance.

• Will readyboost speed up a secondary partion or harddrive?

  - by Sebastian

  I'm building a new computer and plan on using a few spare USB sticks with readyboost to cache disk writes. I'll be running Windows 7 Enterprise SP1 x64 I have a single 2 TB disk, and plan to make a partition for windows (100 GB) and use the rest for data. I know Readyboost will work nicely for the C drive, but am unable to find any information on whether it will accelerate a second drive or partition. Just to clarify, I'm NOT trying to use the harddrive instead of the usb sticks. I'm trying to speed up the second partition using the USB sticks So, will readyboost work for a secondary partion or harddrive?

• When using Windows 2003 DNS Server, how do I configure it to resolve a particular FQDN but rely on e

  - by Corey

  Let's say I have a web-server on my internal network which is behind a NAT router. I have my external DNS for the “xyz.com” domain configured with an A record for “foo” that points to my router's public address. I want my internal network clients to resolve foo.xyz.com to the internal address. However, this is the only xyz.com record that should point to an internal address. Do I need to create a primary zone for xyz.com and mirror all the records from my external zone with the exception of “foo” (this is what I am doing now), or is there a better way?

• How can I move an existing VM's files to a new directory in the same datastore?

  - by blade

  Hi, I have some VMs deployed on ESX. In vSphere 4, I want to move these VMs into another directory in the datastore. So the VM directories are under root, but I want them in root/MyNewFolder. I tried this by turning off a VM, copying the VM's file (VMDK etc) into the directory I want, deleting the hard drive from the VM's settings, adding a new hard drive and then selecting the new path to the VMDK. When I press ok on the settings dialog box, having made this modification to the settings, I get the following error: not found. What I am trying to do also does not seem to be possible when making a new VM. I can only make VMs under root.

• SMTP 25 blocked externally

  - by Jeff

  not sure how to title this question... we run an exchange server with around 80 internal users, all outgoing mail is relayed off a smart host (ISP smtp server) so nothing is actually sent to the world via our server. i wanted to check the server, locally i can telnet to port 25 with no issues and receive the esmtp service ready reply. whenever i do it from an external address (off our local network) i receive unable to connect error 10060. can this cause problems with SPF records, and reverse DNS ? should my exchange server be able to accept smtp requests, requiring authentication before i am able to send from external addresses? if so how... also the exchange server is behind a NAT (asa) device, more than likely thinking that the nat is not configured to route the smtp 25 request to the exchange server.. thanks
