• Guacamole on KVM

  - by Siem Hermans

  I currently run a deployment where I provide virtual machines to circa 25 users through ESXi over the VMWare WSX web portal. This works, no doubt about it, it is fast, stable and reliable enough for the end users. However I stumbled across the Guacamole project (Link: http://guac-dev.org/) and the KVM project (Link: http://www.linux-kvm.org/). I must say I am no genius when it comes to Linux but I am interested in replacing the ESXi and WSX combination with a Guacamole and KVM deployment. I have seen people across the internet use ESXi in combination with Guacamole (mostly prior to the release of WSX), but I have yet to see someone use it in conjunction with KVM. Considering my amount of knowledge on Linux in general I would like to ask: Is it possible at all to combine the two?

• Windows 7 System process reading/writing like crazy

  - by Mats Ekberg

  I have a problem that my windows 7 computer sometimes starts accessing the disk like crazy for maybe 10 minutes at a time. The process in question is the "system" process. I have disabled superfetch and hibernation on my computer, if that makes any difference. I disabled those to see if they were the cause of the problems, but no change. I have 6 GB of RAM and only the web browser was started when I took the screenshot, so I don't think it was thrashing due to page faults. Any ideas on how to find the cause of this?

• CheckPoint SecuRemote / SecureClient on Vista 64

  - by cliff.meyers

  According to this page, CheckPoint's SecuRemote client is not supported on Vista 64: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit%5FdoGoviewsolutiondetails=&solutionid=sk36681 Unfortunately in working with the systems team they will not confirm if the other two clients (SSL Network Extender or Endpoint Connect) are supported by their environment. Does anyone know if it would be possible to do the following? Install VMware Workstation on my Vista 64 system (host) install a Vista 32-bit OS in a virtual machine (guest) Install SecuRemote VPN client within the guest (Vista 32) Get my Vista 64 machine (host) to use the VPN connection from the guest Any other ideas are more than welcome.

• ML 350 additional SATA RAID controller (mirror only)

  - by Nicholas

  I have a Proliant ML350 G8 with two SAS raid arrays currently set up - thereby maxing the default P420i raid controller. I need to set up a large video dump space in addition to this existing set-up (for non backed up, non-critical, temporary storage). I had planned to just add a 2TB SATA disk and plug it into the motherboard. However I it occurred to me the motherboard might have built-in mirror RAID support? Therefore I could use two SATA disks and have some semblance of redundancy. Is this possible? Or would I need to get a cheap raid card? Any recommendations?

• Fatal error on "mode 120000" file during git -> svn migration

  - by Oliver

  Following instructions from the following website: http://code.google.com/p/support/wiki/ImportingFromGit I'm trying to migrate a git repository to svn, but during the "git rebase master tmp" step it fails with the following error after apply the first few patches: $ git rebase master tmp First, rewinding head to replay your work on top of it... Applying: Imported Applying: Cleaned up the readme file Applying: fix problem with versions fatal: unable to write file foobar mode 120000 Patch failed at 0003 fix problem with versions When you have resolved this problem run "git rebase --continue". If you would prefer to skip this patch, instead run "git rebase --skip". To restore the original branch and stop rebasing run "git rebase --abort". I understand that 120000 may refer to a symlink, but Subversion has supported symlinks for a long time now. Subversion installed is 1.6.5, Git is 1.6.3.3. Running on Ubuntu Linux. The system is not running out of disk space and this operation is taking place within my home directory so permissions should not be an issue.

• Best Practices: How can admin deploy software to 100s of PC ?

  - by Gopal

  Hi ... The Environment: I am working for a college. We have a couple of labs (about 100 PCs) for students. At the end of the semester, the PCs will be full of viruses, corrupt system files, all sorts of illegal downloads etc. (everything you can expect from a student environment). At the end of the semester, we would like to wipe out all the systems and do a clean install (WindowsXP + a set of application suites) to get ready for the next batch of students. Question: Is there any free software that will enable an admin to deploy a clean disk image to all the PCs in one go?

• Unable to mount portable hard drive on Ubuntu

  - by VoY

  My portable hard drive (WD My Passport), which used to work correctly now does not automount on my Ubuntu system. It does work on a Windows machine or even when plugged into WD HD TV, which is a Linux based device. There's one NTFS partition spanning the whole drive. When I plug the disk in, I see the following in dmesg: [269259.504631] usb 1-2.2: new high speed USB device using ehci_hcd and address 20 [269259.604674] usb 1-2.2: configuration #1 chosen from 1 choice However it does not mount in GNOME and I don't see it when I type: sudo fdisk -l Any suggestions why this might be? I repaired the partition using chkdsk on Windows, so the issue is probably not filesystem related.

• Updating from OSX Lion 10.7.2 to 10.7.4

  - by Ozair Kafray

  I just got my Mac upgraded to 10.7.2, just to be able to install Xcode 4.3.3. However, when I try to install Xcode 4.3.3, it says that it requires a minimum of OSX 10.7.3. Then using the "Software Upgrade" tool it detects successfully for me that a combined upgrade to 10.7.4 is available. As I select Install Item, the download starts however, it fails after complete download (taking two hours) saying something like "the update cannot be saved". I have done this twice already, and followed it up until 5 minutes were left. I have also checked that there is enough space (60 GB) available on my hard disk, while the update requires around 1.5 GB. The question is what is causing the problem mentioned in bold above.

• Windows 7 backup to 3TB Seagate external drive got 0x8078002A error [migrated]

  - by Zhang18

  I'm using the Windows 7 backup and restore utility to create a system image and personal file backup to an external Seagate GoFlex 3TB disk. I got the following error: One of the backup files could not be created. Details: The request could not be performed because of an I/O device error. Error code: 0x8078002A I searched all over the internet and found these two related discussions (discussion 1 and discussion 2). Note the 1st discussion is for a Western Digital drive, which seem to have a solution with the WD Quick Formatter tool. But I downloaded that software and it cannot detect my Seagate drive. The 2nd discussion is directly relevant but it does not offer a solution. I've spent days on this and am at a loss... Please help if you know what to do to make it work! Thank you!

• OSX Reset Home Permissions and ACLs - how long should it take?

  - by andyface

  Having screwwed up my permissions by trying to have two users accessing one home folder I'm now going through the process of reseting my main user home permissions via the OSX install disk utilities, which seems to be taking a while. Does this process take a while to do, though I assume it depends on how many files I have in the folder, which in my case is a good few 100 GBs. At what point should I be concerned that it may have got stuck and thus reset my computer and try again? I assume, though not sure that if the little circle indicator is still moving then it's not completely frozen, but as there's no progress bar or details I'm not sure how true that is.

• Partitions on Linux and their CHS dependance

  - by FractalizeR

  Hello. Recently I came into a problem with partitioning WD20EARS disk (with 4k sectors). I needed partitions to be aligned correctly so I just used parted in "unit s" mode and started all partitions at mod8 sector (drive itself reports, that sector is 512b) and ended all of them at mod8-1 sector. But then I thought, that may be I should take into account also the cylinder boundaries (I've seen some posts on the net where fdisk complains about partitions not to start/end on cylinder boundary). And then... I thought, that if drive lies about it's sector size, may be it's lying about the whole geometry? Should I care about partitions to be aligned against cylinder boundaries? If so, how do I find these boundaries? I guess each drive model can contain different sectors per track/cylinder... Or sector alignment is all I should take care of?

• Accessing a website's directory in IIS from File Zilla

  - by Cdeez

  I have my Asp.net website deployed in my IIS's Virtual directory. Usually a FTP software like File Zilla is used to upload files to a website's directory from a remote system. File Zilla asks for a Host name, Username, password to connect to the remote server. Now all I want is my users in LAN should be able to access this directory from their system using FTP software like FileZilla. So how can I provide the Host name, username and password to my website's directory. I tried to find it on google but no help. Detailed steps please. Its IIS 5.1 version.

• Manual Duplex for Mac (and/or Linux)

  - by chris_l

  Hi, my printers don't support automatic duplex printing. I'm looking for a solution for my Mac (BTW, also for Linux) that I've seen with most Windows printer drivers: Check "Manual duplex" in the printer screen Printer starts printing one side A dialog appears, asking me to flip the pages Printer prints the other side. One thing I can do, is "print odd pages", then reopen the dialog and "print even pages", but this is very inconvenient, especially when I only want to print a certain page range of the document (the Mac dialog forgets my previous page range every time). It gets even more inconvenient, when printing 2-up double sided, or when changing additional settings for this one printout. So is there maybe some tool, that can do this? Or maybe a "virtual printer driver" that can sit somewhere between the dialog and the actual printer driver, which manages these steps? (The Windows tool http://en.wikipedia.org/wiki/FinePrint can do something like that, but I don't need all of its features - and I need it on Mac/Linux) Thanks, Chris

• Cheapest server per gigabit throughput [closed]

  - by nethgirb

  I'm looking for a set of servers for performance testing a network, and secondarily testing some applications on the servers. Their most important task is simply to pump out data: from an application like memcached or just dumped from a large file in memory into a TCP flow (i.e., disk performance doesn't matter). This should happen over one or more 1 gigabit Ethernet ports, and the machines should run Linux (ideally), or perhaps Mac OS X or some other *nix. Other than that, there are few constraints (e.g., even something ARM-based could be fine). So here's the question: What's the cheapest server per gigabit? Price and power are both considerations.

• Should you disable page file with SSD?

  - by Pyrolistical

  I've been reading http://serverfault.com/questions/23621/any-benefit-or-detriment-from-removing-a-pagefile-on-an-8gb-ram-machine, and it has a lot of great information. But assuming you have more than enough ram, I think page file should be disabled on SSD to extend the life time. I know you would lose the core dump on crash, but not many people need that information. From my understand without a page file as you reach the limit of your ram that might trigger thrashing on disk. But for SSDs there is no concept of thrashing, reads are fast. What do you guys think?

• Loggon to Internet Hotspot from within Linux Terminal

  - by Saif Bechan

  For internet I use a local Hotspot service. I have internet when I start my browser and fill in my username and password. This stays as long as I do not shut down my PC for a while. I run some virtual machines, centos, debian, from the command line. I run these just for small test purposes, nothing special, and security is not an issue for me at all. I want to have these VM's connect directly to the hotspot if this is possible. So they each have there own IP. I have enough hotspot accounts to do so. I can do this with a bridged connection in VMware which works find with a GUI. But I run these OS's from the command line. I only need to know a way how to get the hotspot to validate my credentials. Is there a way of doing this without having a gui.

• Is Hyper-V Server 2008 working on Intel's Atom platform

  - by Josip Medved

  Did anybody try to install Hyper-V on Intel Atom platform? Hyper-V requires: x64 compatible processor with Intel VT or AMD-V technology enabled Hardware Data Execution Prevention (DEP) It seems that both requirements are satisfied with Atom as processor. However, I wonder whether there is some blocking issue (e.g. BIOS that does not support it) since all Atom motherboards I checked had quite old north/south-bridge. My intentions are to run two low-requirements virtual machines (embedded Linux), so performance should not be an issue.

• White Screen of Death

  - by cust0s

  The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

• Mac OS X: pushing all traffic through a VMWare VM [closed]

  - by bj99

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• Troubleshooting Windows Server 2012 storage spaces

  - by Iravanchi

  I'm trying the new "Storage Pools" feature on Windows Server 2012, and I've created several disks on the pool. When I restart the server, some of the disks (two, out of four) do not attach automatically, and don't show up in the list of disks. I can go to Server Manager File and Storage Services Storage Pools, and the faulty disks are listed with a yellow triangle beside them. The drive health in the properties are "unknown". But if I right-click and choose attach, the disk comes online, with all the content on it intact. But after another restart, it's the same story. I didn't find any relevant event in the event log, how can I find out why the drives are not attaching?

• IIS Logs not getting created

  - by Chris

  Hi I have a site running on IIS 6. I have turned on logging on the website tab of IIS and specified a directory for it to write to. Set it to an hourly schedule. However no logs are ever created. Have reset iis. checked disk space and permissions on the directory it is writing to but no logs are ever created. I can see this did work once, as there are logs created in the system32/logfiles directory from about a year ago. Even if I specify that directory nothing new gets created This is on a hosted service What else can I check? Is there any place that errors would be written to that might give me a clue as to what is going on? Have tried event viewer but nothing untoward in there Would appreciate any pointers on this

• Only three primary partitions?

  - by ctype.h

  As everyone probably knows, Windows allows a drive to have four primary partitions, one of which may be active. However, I have only three primary partitions. I shrunk one and created a fourth partition so I could install Windows 8 on it, but Disk Management only allows it to be a logical partition. Why might this be the case? If I cannot convert it to a primary partition, is it advisable to install Windows on a logical partition? If so, is hibernation supported?

• few questions on making a flash drive to a hard drive

  - by user23950

  I've found a tutorial here on how to trick the operating system to see a flash drive as a hard drive. http://www.getusb.info/usb-hack-turn-a-usb-stick-into-a-hard-drive-or-local-disk/ But I have a few questions: This trick will only work on the os wherein you updated the flash drive driver. Is there a trick that will work like this one, but if you plug in the flash drive to another computer it will still be treated as hard drive? How do I convert it back to a flash drive?
