• How do you passthrough native SATA drives to a guest on ESXi?

  - by John

  I have ESXi 4.0 running on an Intel DX58S0 Mothboardboard with an Intel Core i7 930 processor. VT-d is also enabled. I have three drives in the system, drive 0 is used for ESXi. Drive 1 and 2 contain data from an older machine and show up under the "Storage Adapters" section in configuration. I would like to allow a guest machine to access the data on these drives (as nativly as possible). I have enabled passthrough of the motherboard's built in SATA controller (Intel/Marvell 88SE6121 ). This controller shows up in my guest OS, but the guest shows no drives aside from the normal virtual drive. I have tried a Linux guest and Windows7. I have also configured the host machine to try IDE/RAID/ACHI modes for the SATA controller. Any ideas how I can configure one of my guests to get at the raw data on these drives?

• IIS Reverse Proxy support for multiple protocols

  - by Abraxas

  I have a server 2012 machine running IIS. It's in my DMZ and I would like to use it to do reverse proxy for several services. I can get it to route traffic on port 80 to 2 separate internal servers running web apps but there are some issues when I try to forward SSH (not port 80/443) and then when I try to forward OWA (Micrsoft exchange's 'webmail' services) to the internal mail server I run in to issues with guides (like this: http://blogs.technet.com/b/exchange/archive/2013/07/19/reverse-proxy-for-exchange-server-2013-using-iis-arr-part-1.aspx) when they say to have all traffic forwarded to the server farm created for OWA. My question for you all is this - given that there is no more Threat Management Gateway (only runs on server 2008) and ISA 2006 is also dead - is it possible to support multiple types of reverse proxies with different protocols (ftp, ssh, web, ssl-web) in IIS, or would it be better to install a different DMZ OS like a nginx server and use linux firewalls + nginx reverse proxy? Thanks for any help!

• Bootable SD card still has small memory, even after formating

  - by Inazuma

  I have an SD card which I used to run my RaspberryPi. I wanted to update the copy of raspbian on it, so I formated the card using the software from www.sdcard.com. I followed all the instructions correctly, however the size of my SD card didn't go back to it's default. It is a 4gb SD card, which after it's spell in the RaspberryPi had shrunken to 52mb, which I understand is normal. After formatting, the size rose to 3.69gb. This means that there is not enough space to install a new OS, so how can I make my SD card 4gb again? Any help would be much appreciated!

• Mono is frequently used to say "Yes, .NET is cross-platform". How valid is that claim?

  - by Thorbjørn Ravn Andersen

  In What would you choose for your project between .NET and Java at this point in time? I say that I would consider the "Will you always deploy to Windows?" the single most important (EDIT: technical) decision to make up front in a new web project, and if the answer is "no", I would recommend Java instead of .NET. A very common counter-argument is that "If we ever want to run on Linux/OS X/Whatever, we'll just run Mono", which is a very compelling argument on the surface, but I don't agree for several reasons. OpenJDK and all the vendor supplied JVM's have passed the official Sun TCK ensuring things work correctly. I am not aware of Mono passing a Microsoft TCK. Mono trails the .NET releases. What .NET-level is currently fully supported? Does all GUI elements (WinForms?) work correctly in Mono? Businesses may not want to depend on Open Source frameworks as the official plan B. I am aware that with the new governance of Java by Oracle, the future is unsafe, but e.g. IBM provides JDK's for many platforms, including Linux. They are just not open sourced. So, under which circumstances is Mono a valid business strategy for .NET-applications? Edit: Mark H summarized it as: "If the claim is that "I have a windows application written in .NET, it should run on mono", then not, it's not a valid claim - but Mono has made efforts to make porting such applications simpler.".

• CentOS Vs Windows Server 2008

  - by Steve

  Hi, Apologies if the question appears ambiguous, I have little experience in this area and was after some informed opinions. I am deploying a test scenario of a server/client network and need to make some choices for Server. The client will be a Windows system as it meets the requirements for the client, the server choice has more room for selection. From my experience with Linux in general and the appealing nature of open source for low cost, security etc and the availability and performance of database and web server programs I have been considering CentOS as a server choice. I have the ability to make most of the choices of what software / server packages I wish to install. This includes Active Directory (something I have no experience with). How well does this operate with Windows clients? Am I being too selective and creating unnecessary complication by setting out not to use a Windows Server OS?

• VMWare Server lck file keeps coming back

  - by muncherelli

  I am running VMWare Server 2.0 on a Debian Lenny system as a host OS. I am getting this error when I try to start a Virtual Machine Cannot open the disk '/var/lib/vmware/Virtual Machines//.vmdk' or one of the snapshot disks it depends on. Reason: Failed to lock the file. So I looked around on the web and found that I need to delete the .lck folder and file in order to get this error This seems to happen any time I reboot my Debian Server. The Virtual Machines sometimes do not recover and this lck file is causing problems. Should I create a cron script that does a rm *.lck on each of my machines on reboot? Looking for any direction on how to resolve this. It seems when i do a "reboot" command it is maybe not gracefully shutting down the VMware containers so the lock files are still intact?

• When did Apple stop using the name "Macintosh" in favor of "Mac", and does anyone know why?

  - by schnapple

  As of a few months ago I finally joined the ranks of Macintosh owners. Except "Macintosh" doesn't seem to exist anymore for some reason. I noticed everything was "Mac", i.e. Mac OS X, MacBook, Mac mini, Mac Pro, etc. I didn't pay a whole lot of attention, but I always thought everyone was using shorthand. I mean "MacBook" is the real name of the computer, as is "iMac", but I always thought when people said "Mac Pro" they were just shortening the real name, "Macintosh Pro". And yet now when you go to the Apple site, a search for "Macintosh" turns up several instances of the name being used on various things (system requirements for old versions of QuickTime, the occasional piece of software with "for the Macintosh" in the name) but nothing from the main Mac pages. Near as I can tell they're really no longer called "Macintoshes" they're just "Macs" When did this happen, and does anyone know why Apple ditched the term "Macintosh"?

• Sata drive overiding IDE?

  - by Aznbinladen

  I recently just bought a Sata Hard drive and hooked it up and installed a OS. I am making it my Primary hard drive. What I had before that though was 2 IDE hard drives that I used. One of them was my Prime and the other one was just a second to keep stuff on. My problem is that now since I hooked up the Sata drive, my IDE drives are not being detected at all. I even tried to remove the Sata drive completely and use my IDE drives, but it couldn't be detected. What should I do? Am I connecting them wrong?

• Virtual Machine files on ramdisk doesn't run faster than on physical disk

  - by Landy

  I installed total 36G memory (4x8G + 2x2G) in the host (Windows 7) and I used ImDisk to create a 32G ramdisk and format it to NTFS file system. Then I copied the virtual machine (in VMware Workstation format) folder, including vmx, vmdk, etc... to the new created ram disk. Then I tried to power on it in VMware Workstation. What made me surprised is that the performance is not better than before. It cost almost the same time to power on the Windows 7 VM. I check the Resource Monitor in the Windows 7 host, and the statistics of CPU, disk, network are rather normal. The memory has reported 3000+ hard fault/sec when guest OS boot then drop to 0 after the guest powered on. Any idea about this issue? I had thought the performance of ramdisk will be better than physical disk in this case. Am I wrong? Thanks.

• Installed Windows 8 Upgrade AFTER Formatting HD - any way to activate?

  - by Brandon Vogel

  I had an XP system - formatted the HD then ran Windows 8 Upgrade install. Install was fine. It cannot activate and gives me the 'this is an upgrade' error. Is there ANY way to fix this (MS Support call or something?) before I scrap the entire Windows 8 install, Reinstall XP, then upgrade to Windows 8 the proper way? I hate to waste the day's worth of config-the-new-os time if not absolutely necessary. Error was the 0XC004F061 from Windows 8.

• How is the Ubuntu installation supposed to work?

  - by Bob D

  I have given up on installing Ubuntu 12.04.01 for the sixth time. I finally got Windows XP to work again. So I blitzted the Ubuntu partition and the swap partition and was about to install the sixth try when it occurred to me that ought to ask how is is "supposed" to go. My installer will install Ubuntu on the Linus ext4 partition I created by hand in Windows on my C drive. But the installer keeps insisting on installing the OS on my D drive unless I intervene. So if I choose "do something else" it will accept installing Ubuntu on the C drive in the partition I previously created, but it insists on putting the "Device for boot loader installation" on the D drive. I can select a different drive at this point (where I could not with the "along side windows choice) but what drive to I choose??? It lists sda, sda1, sda5, sdb and sdb1. The five times before this all ended in disaster letting the installer choose. So I need human intervention. Where is the safe place to do this. The results from the previous attempts left me with only the Ubuntu that would boot, the boot to windows from the grub menu failed every time. Is there a better version of Ubuntu I can use? Is V12.04.01 messed up? My goal is still to use Wine on it to run PC programs. I would like to find a shell or skin or something that makes it seem like windows but have the security and power of Linux under the good. I have seen this type of system and it worked very well. I know I am getting long winded but I have been though at least four of the seven rings of hell already, so I want this install to be the last.

• Ubuntu 13.04 to 13.10: Filesystem check or mount failed

  - by SamHuckaby

  I attempted to upgrade from Ubuntu 13.04 to 13.10 today, and mid upgrade the system started flaking out, and eventually locked up entirely. I was forced to restart the computer, and am now unable to get the computer to boot up at all. When I boot currently, it takes me to the GRUB menu, and I can choose to boot normally, or boot in an older version. I have tried several things, which I list below, but no matter what, when I try to finish booting into Ubuntu, I receive the following error: Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further errors will be ignored root@ubuntu-computername:~# I have fun fsck -f and everything appears correct, no errors are reported. and it passes all 5 checks. If I run fdisk -l then I get the following information: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes Disk identifier: 0x00010824 Device Boot Start End Blocks Id System /dev/sda1 * 2048 608456703 304227328 83 Linux /dev/sda2 608458750 625141759 8341505 5 Extended Partition 2 does not start on physical sector boundary. /dev/sda5 608458752 625141759 8341504 82 Linux swap / Solaris Disk /dev/sdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0fb4b7e8 Device Boot Start End Blocks Id System /dev/sdb1 8192 625139711 312565760 7 HPFS/NTFS/exFAT I am considering just installing a new OS on the other disk, that currently has nothing on it, and then just attempting to scrape my data off the old disk (thankfully I didn't encrypt the files).

• What emulator / VM software can I use to create a Win32-portable Linux Guest?

  - by Jotham

  Hi, I want to create a portable VM setup so that I can boot a Linux install regardless of which Windows XP / Windows 7 host machine I am on. I was looking at Qemu but it doesn't appear to have a relatively safe win32 build. Other things like VirtualBox require complete install on the host OS for performance reasons. I'm not so concerned about performance, I just want to run a few curses based applications. My ideal end goal would be a a memory stick of some size with a VM/Emulator I can boot on most WinXP/Windows 7 machines and access my own curses based applications (probably archlinux or debian). Any help would be appreciated. Regards,

I've created a Live USB of Windows 8 using Windows 7 USB/DVD Download Tool - Yes, I know it says Windows 7 but I've been doing research and I am hearing from everywhere that it also works for Windows 8. The ISO was loaded on just fine (AFAIK) Computer came with Windows 8 pre-installed I have Safe boot and Fast boot disabled in the BIOS Settings I have USB as my first boot option I have tried both the USB 2.0 and 3.0 ports Yet, Mint is all that will boot up. Anybody have a similar issue? If it helps, the computer is a Toshiba Satellite S855D Laptop with an AMD APU quad-core processor (3 CPU, 1 GPU)

• Can you run Android 2.2 Froyo or 2.3 Gingerbread in a VM?

  - by Josh B

  I came across a how-to guide for running Android 1.7 in a virtual machine (VirtualBox), but 1.7 is old. I haven't been able to find a Android 2.2 or 2.3 image anywhere, does anyone have any ideas on how to virtualize newer Android OS's? Preferably a free virtualization solution like VirtualBox. Here is the link about virtualizing 1.7: http://osxdaily.com/2010/12/14/run-android-using-a-virtual-machine-on-a-mac-or-windows-pc/ They send you to here to download Android disk images: http://virtualboxes.org/images/android-x86/ But I can't find anything newer than 1.7, anyone have any ideas? Is this considered illegal or piracy is that why there are no images available? Thanks for help!

• Why does iChat Server keep connecting to proxy.eu.jabber.org?

  - by Tom Hamming

  I have OS X Server 10.6.5 running on a new Mac Mini (server model), serving several functions among which is iChat Server (iChat and Pidgin on Windows as clients). In the iChat log in Server Admin, I kept seeing entries about connecting to proxy.eu.jabber.org. It's for our office network and I wasn't excited about external access to it, so I disabled server-to-server XMPP federation and now the connections just time out. But why is it doing that in the first place? Sample log entry: (datetime) (servername)jabberd/resolver[portnum]: [xmpp-server._tcp.proxy.eu.jabber.org resolved to 208.68.163.220:5269 (300 seconds to live) then: sending dialback auth request for route '(full server hostname)/proxy.eu.jabber.org' A couple minutes later, it comes back with: dialback for outgoing route '(full server hostname)/proxy.eu.jabber.org' timed out

• stdout and key press

  - by Jack

  Hi, when in console, if I press a key, some interrupt controller sends code of that key to CPU, which looks into some table and than represent that keypress by printing some charracter to stdout. But, is keyboard sending an ASCII code of that key, or just some standardised code? Since there is so many languages and extra characters, OS must further translate its code into some character according to user selected scheme, I guess. I ask, becouse I am from Czech Republic, and we use some characters that do not exists in standart ASCII code. So I was thinking, if I enter this character into a console, and then print it, lets say in C++ using cin and cout, and I have set locale to Czech, stdin must actually send some non-ASCII code of the character I pressed to input stream. Am I right?

• Everytime I click on a link from within Mac, parallels boots up my Windows VM and opens the link there

  - by Christoph

  Everytime I click on a link from within Mac, parallels boots up my Windows VM and opens the link there. That's super annoying and I haven't found a configuration to change it. In the settings of my Windows VM there is an option where to launch the webbrowser. However that seems to only affect links that I open from within my Windows session. UPDATE I just stumbled across this answer: How to disassociate a file type with an application in Mac OS So I disabled "share windows apps with mac" completely. Also this seems to be overly protective it at least does the trick. I think it also deactivates that running windows apps show up in the dock but I don't care that much about that anyway.

• Route an IP from WAN to a host on LAN on OpenWRT

  - by Zsub

  EDIT: I know how to use NAT, I specifically want the server to be reachable on two IP's, one private, one public, with the firewall of the OpenWRT in between, if feasible. At the office we have recieved a /29 from our ISP. The first address is reserved for their endpoint, so I'm free to use five addresses. We run a local network, so of course there is a router in between running OpenWRT to provide all hosts with (W)LAN (dhcp from a private range). However, we also have a server running OS X Server 10.6 (Snow Leopard) and I'd like that server to be accessible both from the LAN using a private IP as well as from the WAN on it's own public IP. Point of note is that the server only has one network port, so multiple NICs is not an option, unfortunately. How would I go about doing this?

• Macvim lags while Vim on terminal is buttery smooth

  - by SaamJB

  I am running OS X Lion 10.7.3 and Macvim runs significantly slower than vim on the terminal for me. All movement commands in Macvim are much slower. Moving up and down in visual mode is equally as laggy. I see none of this lag when using vim from the terminal. Does anyone know what the reasons may be? I am running NERDtree on every open tab, and I know this contributes some memory overhead and potentially some slow down; but even when I don't run NERDtree Macvim runs much slower than vim from the terminal. Any help in solving this would be greatly appreciated.

• MacBook Refuses to Boot

  I have a MacBook that has unfortunately died on me. I randomly got a pop up message that said I needed to restart my computer, and once I did, I was greeted with the blinking folder question mark start up screen. I've tried everything, including running Disk Utility repair and reformatting the hard drive and reinstalling OS X. All of my data is backed up and safe, I just need my computer to start again. Before I go off and buy a new hard drive, I wanted to see if there is anything I might have forgotten.

• replace windows xp with ubuntu no usb boot option and no cd?

  - by kristian nissen

  I have an old laptop running windows xp, I want to replace it with the latest version of ubuntu. The problem is that the laptop does not support boot from usb - I checked the BIOS but the option is not working, I tried http://www.pendrivelinux.com/testing-your-system-for-usb-boot-compatibility/ but with no luck. I also tried burning the iso on a dvd but the burn process keeps failing. What options do I have? Isn't it possible to install ubuntu somehow by downloading it and replacing it with the current OS?

• I'm running Ubuntu notebook on a USB drive with 1GB persistence. Where are my XAMPP files?

  - by CDeanMartin

  I just began running Ubuntu Notebook on my 2GB USB stick, with 1GB persistence. After I installed XAMPP, I rebooted to make sure the persistence was working. It worked! My XAMPP installation worked, and it comes up when I type localhost into the browser. The sample apps work, including the ones using MySQL. But I can't find the application files! I am used to the vast labyrinth of files in Windows Explorer, and looking through 'Files and Folders' in GNOME, there seem to only be 7 or 8 folders in the entire OS? What is really going on here? I looked through them all and where is XAMPP? When I code PHP with a WAMP stack, all the .php files go in the 'WWW folder' What is the Linux equivalent of the WWW folder?

• Anti Aliasing dead

  - by Gazoza

  I have a problem with anti-aliasing. No matter the software settings, it seems to be gone. I tried driver updating and reinstalling, cleaning of the hardware, different monitor with different cablies, OS reinstalling and changing, none of which helped. I decided to change the graphic card, but that didn't work either. Moreover, I have a distinct impression that the jagged edges are worsening as time goes by. I think this is a hardware-related issue, but I don't know exactly what to do. If anyone here had similar troubles, and/or has an idea how to cope with them, I'd be very grateful. My current card is a nVidia GT610.
