  • "Dictionary problem." Error with VMPlayer

    - by George Mauer
    I'm pretty new to using vmware virtualization (been a virtualbox user) so I'm hoping you guys can help me out. I recently got an external usb disk containing a vm for a client, downloaded vmplayer, set it up with "Open a Virtual Machine", ran it, easy as pie. After working with it a bit this morning, I shut the VM down and now trying to start it back up again I get this: I tried removing the vm from my library, now it happens whenever I try to add it back in. In the meantime, I can still access other virtual machines so it seems like the problem might be with the virtual disk. So two questions: This is obviously not a very helpful error message. Where can I go to get more information? My Application EventLog doesn't contain anything from VMWare. What steps can I take to fix the problem? Edit: A couple more pieces of information. I did not take any snapshots. I don't think VM Player even has that ability. I have a zip file of (what I assume) is the state of the VM when it was sent to me. I cannot unzip it as it is huge and simply requires more HD space than I have available but I did extract the vmx file and examine it. Other than the UUIDs and the fact that mine reads cleanShutdown = "FALSE" they are identical. The log contains the following lines Jun 23 10:11:18.080: vmx| SNAPSHOT: SnapshotConfigInfoRead: Unable to load dict from 'E:....\MachineName.vmsd'. Jun 23 10:11:18.080: vmx| SNAPSHOT: SnapshotConfigInfoRead failed for file 'E:....\MachineName.vmx': Dictionary problem (6) Jun 23 10:11:18.082: vmx| SNAPSHOT: Snapshot_TimeStampTiers failed: Dictionary problem (6)

  • Why does BitLocker need a minimum volume size of 64 MB?

    - by Iszi
    Since the future of TrueCrypt appears to be still unclear, I figured I'd try to get my stuff migrated into BitLocker at least for the time being. I nearly never have to access my encrypted data from anything that's not BitLocker-capable, so cross-platform compatibility isn't a big deal to me at this time. However, I am having a bit of an issue understanding the minimum requirement of a 64 MB volume. With TrueCrypt, I was able to protect small files (and most of my protected files are fairly small) in containers down to 300 KB or even less. When I finally created a VHD of an appropriate size last night (100 MB), it seemed the file system itself only took up about 3 MB and encrypting it with BitLocker didn't appear to take up any more. While 3 MB is still an order of magnitude larger than the smallest volume I could make with TrueCrypt, it's still relatively reasonable in comparison to 64 MB. This is an especially large amount of overhead (and largely wasted at that, since it's mostly empty space for now) when I consider that some of these volumes will be stored and synced in the cloud. What possible reasons could BitLocker have for needing volumes to be 64 MB large, when it's not even appearing to use that space? BitLocker FAQ on TechNet

  • Can't mount Linux usb disk. It just create /dev/sg device but no /dev/sd

    - by MTilsted
    I have a Corsair R60 ssd disk which is a disk with both sata and usb connectors. But the usb thing seems to be a bit non-standard, or maybe its just my fedora linux. When I insert the disk using a usb cabel to a running Fedora 14 linux system, a device called /dev/sg3 is added but that is all. No new /dev/sd* device is created so I can't mount the disk. If I look at cat /proc/scsi/sg/device_strs I get ATA Hitachi HTS54321 FB2O HL-DT-ST DVDRAM GSA-T50N RP05 Seagate Desktop 0130 Corsair CSSD-R60GB2 So the disk is there. (The last entry) but my linux will for some reason not see it as a usb hard disk. When I insert other usb disks they work fine. It is only this specific disk which causes problems. I have tried on 3 different computers with the same result. A hint to the problem may be that if I add the disk to a windows system(With usb) the disk is called "A fixed disk" and not a portable disk as expected. The disk works fine with linux If i connect it with the sata cabel, but I would really like to have it working with usb too. (To mount it on computers without sata). Added: I did try to mount /dev/sg3 but mount say that its not a block device. (File say Its a character special device). Added output from dmesg: [ 97.454073] usb 7-1: USB disconnect, address 2 [ 105.913055] hub 2-0:1.0: unable to enumerate USB device on port 3 [ 107.048054] usb 2-3: new high speed USB device using ehci_hcd and address 5 [ 107.162900] usb 2-3: New USB device found, idVendor=1b1c, idProduct=1ab8 [ 107.162903] usb 2-3: New USB device strings: Mfr=1, Product=2, SerialNumber=5 [ 107.162906] usb 2-3: Product: CSSD-R60GB2 [ 107.162908] usb 2-3: Manufacturer: Corsair [ 107.162910] usb 2-3: SerialNumber: 10111441000000990069 [ 107.167651] scsi7 : usb-storage 2-3:1.0 [ 108.195543] scsi 7:0:0:0: Direct-Access Corsair CSSD-R60GB2 PQ: 1 ANSI: 0 [ 108.197732] scsi 7:0:0:0: Attached scsi generic sg3 type 0

  • Where do these mysterious DNS lookups come from and why are they slow?

    - by Hongli
    I have recently obtained a new dedicated server which I'm now setting up. It's running on 64-bit Debian 6.0. I have cloned a fairly large git repository (177 MB including working files) onto this server. Switching to a different branch is very very slow. On my laptop it takes 1-2 seconds, on this server it can take half a minute. After some investigation it turns out to be some kind of DNS timeout. Here's an exhibit from strace -s 128 git checkout release: stat("/etc/resolv.conf", {st_mode=S_IFREG|0644, st_size=132, ...}) = 0 socket(PF_INET, SOCK_DGRAM|SOCK_NONBLOCK, IPPROTO_IP) = 5 connect(5, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("213.133.99.99")}, 16) = 0 poll([{fd=5, events=POLLOUT}], 1, 0) = 1 ([{fd=5, revents=POLLOUT}]) sendto(5, "\235\333\1\0\0\1\0\0\0\0\0\0\35Debian-60-squeeze-64-minimal\n\17happyponies\3com\0\0\1\0\1", 67, MSG_NOSIGNAL, NULL, 0) = 67 poll([{fd=5, events=POLLIN}], 1, 5000) = 0 (Timeout) This snippet repeats several times per 'git checkout' call. My server's hostname was originally Debian-60-squeeze-64-minimal. I had changed it to shell.happyponies.com by running hostname shell.happyponies.com, editing /etc/hostname and rebooting the server. I don't understand the DNS protocol, but it looks like Git is trying to lookup the IP for Debian-60-squeeze-64-minimal as well as for happyponies.com. Why does Debian-60-squeeze-64-minimal come back even though I've already changed the host name? Why does Git perform DNS lookups at all? Why are these lookups so slow? I've already verified that all DNS servers in /etc/resolv.conf are up and responding slowly, yet Git's own lookups time out. Changing the host name back to Debian-60-squeeze-64-minimal seems to fix the slowness. Basically I just want to fix whatever DNS issues my server has because I'm sure they will cause more problems that just slowing down git checkout. But I'm not sure sure what the problem exactly is and what these symptoms mean.

  • nginx hackery : change image file every X request

    - by Vangel
    Let me describe what I am trying to do first. I have a bunch of pictures in a directory called /images/*.(jpg|gif|png|blah blah|) Now say these images are embedded in an html page and I dont really care which image or where its embedded. For every 10th request for the same picture file (if possible) or for any picture I want to display a fixed image (e.g. trollface.jpg). thats it! I have searched around a bit but i am not even sure what I am looking for. Rewrite might help but then its a permanent thing. this has got to do something with requests. I have heard perl scripts can be used with nginx. I can't write an nginx module (though I did bravely lookup the docs and then gave up) Before you ask "But why don't you do it in application, noob?". This is a static files only server. The point is to not execute any binary at all.

  • What is the best private cloud storage setup

    - by vdrmrt
    I need to create a private cloud and I'm searching for the best setup. These are my 2 most important requirements 1. Disk and system redundant 2. Price / GB as low as possible The system is going to be used as backup setup which will receive data 24/7 over SFTP and rsync. High throughput is not that important. I'm planning to use glusterfs and consumer grade 4TB hard-drives. I have worked out 3 possible setups 3 servers with 11 4TB HDD Setup up a replica 3 glusterfs and setup each hard drive as a separate ext4 brick. Total capacity: 44TB HDD / TB ratio of 0.75 (33HDD / 44TB) 2 servers with 11 4TB HDD The 11 hard-drives are combined in a RAIDZ3 ZFS storage pool. With a replica 2 gluster setup. Total capacity: 32TB (+ zfs compression) HDD / TB ratio of 0.68 (22HDD / 32TB) 3 servers with 11 4TB consumer hard-drives Setup up a replica 3 glusterfs and setup each hard-drive as a separate zfs storage pool and export each pool as a brick. Total capacity: 32TB (+ zfs compression) HDD / TB ratio of 0.68 (22HDD / 32TB) (Cheapest) My remarks and concerns: If a hard drive fails which setup will recover the quickest? In my opinion setup 1 and 3 because there only the contents of 1 hard-drive needs to be copied over the network. Instead of setup 2 were the hard-drive needs te be reconstructed by reading the parity of all the other harddrives in the system. Will a zfs pool on 1 harddrive give me extra protection against for example bit rot? With setup 1 and 3 I can loose 2 systems and still be up and running with setup 2 I can only loose 1 system. When I use ZFS I can enable compression which will give me some extra storage.

  • Change default profile directory per group

    - by Joel Coel
    Is it possible to force windows to create profiles for members of one active directory group in a different folder from members in another active directory group? The school here uses DeepFreeze to protect public computers. In a nutshell, DeepFreeze prevents all changes to a hard drive such that every time you restart the machine the disk is identical to it was at the time you froze it. This is a bit different than restoring to an image, in that it never really wrote changes to disk in a permanent way in the first place. This has a few advantages over images: faster recover times, and it's easy to thaw the machine for a few minutes to perform maintenance such as windows updates (which can even be automated). DeepFreeze also allows you to configure a "thawspace" partition, where changes are persistent across reboots. One of the weaknesses of DeepFreeze is that you end up needing to create a new profile every time you log in, unless your profile existed at the time the machine was frozen. And even then, any changes you make to your profile while working on a frozen machine are lost. As students have frequent legitimate needs to log in to our classroom machines, there is currently a lot of cleanup involved from time to time in removing their old profiles and changes, so I want to extend DeepFreeze to protect our classroom computers as well as public computers. The problem is that faculty have a real need to keep a stateful profile locally on these classroom computers. The solution I would like to use is to configure Windows via group policy (or even manually, if that's the way I'll have to do it) to place profile folders on the thawspace partition, but only for members of the faculty security group. Is this possible?

  • Recent DDE / file open issue with Office 2007 affecting only a few machines, is a Windows Update to blame?

    - by kafka
    All our workstations run Windows 7 Professional 64 bit. It started with one, then another, then another couple of machines having a problem accessing Word files locally and on the network. This doesn't happen on my machine though. Affected users get the error message 'There was a problem sending the command to the program'. I've Googled for solutions, but none of the answers worked. They suggested deleting certain registry keys; unregistering and reregistering the program for DDE; resetting the way that the shell opens .docx programs etc. each to no avail. As it affects local and network shares I believe the problem lies with the clients, and not the server, and I'm starting to suspect that there could have been a recent Windows Update which has caused this. I've tried comparing the updates on my working machine with an affected machine, but I can't immediately see any major differences. Has anyone else recently encountered this problem? What are the best steps to take to further isolate what could be causing this?

  • The BitLocker encrypted logical drive of my laptop is not accessible. On clicking error appears,"Application not found"

    - by Nauman Khan
    I had an important personal data that was stored in my laptop drive 'F'. My 4 year old son also uses my laptop to play games. To secure my data I used bitlocker software that was already there in my windows 7 ultimate 32 bit. I am using a Dell D 630 Core2Duo laptop. The thing worked fine for me and I have been able to access my data in drive 'F' as and when I required. But today, when I tried to open my 'F' drive, an error box appeared saying "Application not found". I right clicked and checked 'properties' of 'F' drive. It showed me Used Space = 0 bytes and Free Space = 0 bytes. I opened 'Disk Management' which showed my 'F' drive file system as 'Unknown (Bitlocker Encrypted). 'Disk Management' is also showing my 'F' drive as healthy logical drive. I opened 'Manage bitlocker' and found that my 'F' drive was being shown locked and 'Unlock Drive' was displayed against it, however, when i click on 'Unlock Drive', it does not function. I opened 'TPM Administration' and found an information that 'Compatible TPM cannot be found'. My bitlocker encryption was working fine which means that I had a compatible TPM in my laptop. Where has it gone? How can I enable it? Is my 'F' Drive lost forever and thus the data in there as well?

  • IBM BladeCenter S: Disk Configuration

    - by gravyface
    Have just the one storage bay right now (SAS 15K 600GB x 6) and have configured one storage pool in RAID 10 with 4 disks (and two global spares). For each blade, I've created a volume and mapped accordingly: Blade #1 400 GB Blade #2 200 GB Blade #3 100 GB Blade #4 100 GB When I boot up Blade 1 and enter into the UEFI Setup (F1) followed by the Adapters and UEFI Drivers LSI Logic Fusion MPT SAS Driver Utility, I see 4 disks: two are the on-board 73GB drives, the other two are 200GB each and assume I'm being presented with two logical disks from the volume I created and mapped to this blade. I was a bit surprised by this: I figured I would've been presented with one logical drive per volume, not two. I'm assuming I can just configure whatever RAID level I wish that supports two disks, but not really sure what the benefits/trade-offs here. Should I go with RAID 10 on top of RAID 10? RAID 0? Software RAID 0/1/10? Does it even matter? If this is "normal" to see two disks, then I'm going to likely just do some benchmarking and see if it makes a difference changing the RAID levels (my guess is no); if this is not normal, well, please let me know. :)

  • Outlook 2010 - Missing New Mail Envelope Icon

    - by sdoca
    I've seen a number of posts related to this issue, but none with a solution that works for me. I have: Windows 7 Professional 64 bit Office/Outlook 2010 "Show an envelope icon in the taskbar" checked "Hide When Minmized" selected "Show icon and notifications" selected for Outlook in my taskbar settings This used to show me the envelope icon in my notifications area. Then something happened with my user profile and the sys admins created me a new one. Since then, the envelope only displays if Outlook is not minimized. It doesn't matter if I unselect "Hide When Minmized", the icon still doesn't display when new mail arrives. If I select "Display a Desktop Alert", then the icon is displayed. However, I HATE the desktop alert as I find it too intrusive/distracting. Is there some way to just get the envelope icon working (again)? UPDATE More testing and sometimes I will and sometimes I won't get an envelope icon with the desktop alert turned on. This is driving me nuts!! UPDATE TWO I like my notification area of the taskbar to be clean. So, all icons are set to "Only show notifications" except for Outlook as noted above. I've noticed the envelope icon is being displayed in the expanded notification area when I click on the up arrow to view all icons. So, it is being added to the notification area, but not displayed. It's a rather useless feature now...

  • Discover the public ip of a network without being connected

    - by Martin Trigaux
    Let say, I'm next to a network and can see the traffic (with airodump or similar tool) but can not decipher it (because I am not connected on the network). Is it possible to discover the public ip address of the network ? I know the MAC address of the users connected on the network but do I know the one of the router ? If yes, maybe there is a way to do the matching. I know IP addresses are not forever but some addresses are static and never change. Maybe there is a database of MAC address having recorded that. Google has a database that match MAC address and geographical coordinates so why not with IP addresses ? Other idea, if I know where am I, I can maybe guess the IP range used in the city by the ISP (is it findable ?) and then try to "ping" each IP on the range (if it is a /24, it's possible, even /16 maybe). Will I get some information like the MAC of the box or see some traffic on the network ? These are two ideas I had. I don't know if they are doable, certainly not perfect. Do you think of some others ? By trying several methods, maybe I can get a guess with a bit of luck. Thank you

  • vSphere - datastore falling off a host

    - by Chadddada
    Recently we have been running the vCheck powershell script daily in order to help in monitoring our vSphere ESX 4.0 environment. One of the oddities that we have been seeing is that some of the datastores on the SAN don't always show up on every host. Our hosts are connected redundantly, via FC, to some brocade FC switches, which then connect via fiber to our EMC Ax4 SAN. While all the datastores are presented to each host we have, and they see them initially, they sometimes seem to fall off and are no longer visible. It easy enough to rescan for datastores and add them back to the hosts the hosts but this seems to be an error. Has anyone else seen this or know why it may be happening? Responses to questions: 1. Is it always the same ESX servers that lose their connection? – Scott Warren No this happens randomly on random hosts. If a VM is running on a particular host, of which the VM's disks are on a SAN datastore, then that datastore won't disappear. It seems to happen if a host doesn't touch a datastore for a bit and it just forgets about it.

  • USB seems to pause system

    - by Marco van de Voort
    I've an application that does some simple measuring, for which it polls a few 100kbs several times a second (8-25 times) The behaviour is not really dependant on chipset (happens on several mobo's intel 965- P55) and OSes (XPsp3 and win7). Also the make of the USB keyboard doesn't seem to matter. I notice that sometimes when an USB kbd is plugged in, the system pauses for say 500-1000ms. (about 900-1000ms on disconnect, and 400-500 on the subsequent connect) It also happens for other USB devices (most notably mice and massstorage devices), but only the first time such device is connected to an installation. This disrupts the measurement and I really would like to get rid on this. I already tried to disable as much as possible. (powersave, teletubby mode (*) etc), and while this helped with the non-USB related disruptions of the measurement, it doesn't help with the USB related ones. (*) fyi, turning off themes (to resp. classic/non-aero), and turning off effects in system solved problems that occured when minimizing/maximizing the app. Any pointers to look into? I'm a bit stuck with this.

  • Safe use of Update-FormatData?

    - by Steve B
    In a custom PowerShell module, I have at the top of my module definition this code: Update-FormatData -AppendPath (Join-Path $psscriptroot "*.ps1xml") This is working fine as all .ps1xml files are loaded. However, the module is sometimes loaded using Import-Module MyModule -Force (actually, this is in the install script of the module). In this case, the call to Update-FormatData fails with this error : Update-FormatData : There were errors in loading the format data file: Microsoft.PowerShell, c:\pathto\myfile.Types.ext.ps1xml : File skipped because it was already present from "Microsoft.PowerShell". At line:1 char:18 + Update-FormatData <<<< -AppendPath "c:\pathto\myfile.Types.ext.ps1xml" + CategoryInfo : InvalidOperation: (:) [Update-FormatData], RuntimeException + FullyQualifiedErrorId : FormatXmlUpateException,Microsoft.PowerShell.Commands.UpdateFormatDataCommand Is there a way to safely call this command? I know I can call Update-FormatData with no parameters, and it will update any known .ps1xml file, but this would work only if the file has already been loaded. Can I list somewhere the loaded format data files? Here is a bit of background: I'm building a custom module that is installed using a script. The install script looks like : [CmdletBinding(SupportsShouldProcess=$true,ConfirmImpact="High")] param() process { $target = Join-Path $PSHOME "Modules\MyModule" if ($pscmdlet.ShouldProcess("$target","Deploying MyModule module")) { if(!(Test-Path $target)) { new-Item -ItemType Directory -Path $target | Out-Null } get-ChildItem -Path (Split-Path ((Get-Variable MyInvocation -Scope 0).Value).MyCommand.Path) | copy-Item -Destination $target -Force Write-Host -ForegroundColorWhite @" The module has been installed. You can import it using : Import-Module MyModule Or you can add it in your profile ($profile) "@ Write-Warning "To refresh any open PowerShell session, you should run ""Import-Module MyModule -Force"" to reload the module" Import-Module MyModule -Force Write-Warning "This session has been refreshed." } } MyModule defines, as first statement, this line : Update-FormatData -AppendPath (Join-Path $psscriptroot "*.ps1xml") As I updated my $profile to always load this module, the Update-Path command has been called when I run the install script. In the install script, I force import the module, which be fire again the module, and then, the Update-Path call

  • CPU operating temperature ranges

    - by osij2is
    I have an AMD Phenom II 960T with 2 cores unlocked for a total of 6 cores. I don't overclock at all. I have a Arctic Cooling ACALP64 Heatsink/Fan installed. I'm currently running ESXi 5.0 so I have to go into the BIOS to read the CPU temperatures, which at idle seem to be in the 71-74C range. To me, this is pretty high, but I cannot find any official temperature ranges that AMD says the CPU can work well within. There seems to be a lot of questions on superuser and numerous forums around CPU temperatures but no one seems to have a clear consensus as to what the manufacturer temperature ranges are for specific CPUs. I've tried searching through AMDs site to no avail. At this point, I'd be willing to shut off the 2 extra cores if it keeps the heat down but until I get some sort of tolerance or range for temperature, I have no idea if the CPU is being damaged or not. Can anyone point to a direct source, article, FAQ from AMD that specifically states their CPUs temperature range? Or are CPU temperature ranges so varying that there's no possible baseline? Am I being too paranoid about this? To me, anything over 65C is a bit much and if I'm in the low-mid 70s range with NO VMs running, what can I expect if I have several VMs running?

  • Slow connection to Linux MySQL from Windows only (XAMPP)

    - by Josh
    I'm having a problem with a PHP project (using Kohana 3.2 framework) on my Windows 7 64-bit machine connecting to the database. The development database is stored on a Ubuntu Linux server on the local network. Other development machines running OSX and Linux are connecting fine. There are no other Windows development machines to test with. I can access MySQL fine using MySQL Workbench, and other projects (which I believe to be less database heavy) run mostly ok, only occasionally getting timeout messages. I'm constantly getting Maximum execution time of 30 seconds exceeded when functions such as mysql_query() are run in this particular project. Specifically, the Kohana file where the timeout occurs is MODPATH\database\classes\kohana\database\mysql.php [ 186 ]. My local set-up is: Windows 7 Professional 64bit XAMPP 1.7.7 (PHP 5.3.8) The output of uname -a of the Linux server is: Linux peach 2.6.38-11-server #50-Ubuntu SMP Mon Sep 12 21:34:27 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I've tried the following, with no success: Disabling Windows firewall Switching between using a persistant and normal connection In my.cnf, adding skip-name-resolve Increasing wait_timeout Enabling bind-address I've run out of ideas now, and have no idea how to debug an odd issue like this. Has anyone come across this before, or have any idea how I could find the root of the issue, or what might be the problem?

  • PCI Tv Tuner not receiving signal

    - by C-dizzle
    I inherited an Angel II PCI Dual TV Tuner card, popped it into my computer's PCI slot, plugged in my coax cable, but am having trouble getting any type of signal to it. The computer I am using is Windows 7 Ultimate 32 bit, I know the card works because the computer recognizes it and installs the drivers, or at least I assume it works because of that. I'm trying to use Windows Media Center to watch/record tv. Here are a few things I have tried to get it working: Uninstalled/Reinstalled the newest drivers Tried hooking up an antenna to the coax input instead of my cable Instead of using cable splitter, went directly from wall output into card with coax cable Tried using different output on splitter in case the out port was bad I haven't tried a different coax cable yet, it should be fine since it's pretty new. Since this is my first time setting up a TV Tuner card, is there anything specific that I need to do with it? Is there any configuration that needs to be done on it? Do I need to have a digial receiver? I was getting pretty frustrated with it so I wanted to turn here to the experts, I'm sure someone can help me figure it out.

  • What methods are available for updating a non-Internet-connected VMWare ESXi host?

    - by romandas
    I have a stand-alone installation of VMWare vSphere Essentials, with a vCenter Server and 3 ESXi 4.0 host servers. The environment is intended to remain as a stand-alone network, with the exception that I can "float" a workstation or server between the 'Net and the VMWare network for patches and maintenance. With other installations, where the Internet is available, I've used the vSphere Host Update utility to connect to VMWare and then apply the patches to the ESXi hosts. My problem is that this utility does not seem to function if it cannot connect to both VMWare and the ESXi host at the same time, as the scan for patches function will not scan the server without connecting to VMWare's site to sync its repository first. Even if I sync it, disconnect from the 'Net and connect to the VMWare network, it still won't scan hosts for required patches -- it will prompt for syncing with VMWare and if you click No to syncing, the scan does not occur. Does anyone know of other options for updating the ESXi hosts in some automated fashion? I believe I can manually pull down required patches and apply them, but this will not scale well, and in the future I'm sure I'll want something a bit more scalable.

  • Ubuntu 12.04 Very slow especially with Android Studio

    - by Nada
    I have an old laptop with the following specification: Memory: 485 MiB, Processor: Genuine intel CPU T2300 @ 1.66 GHz ×2, OS Type: 32 bit, Disk: 78.1 GB, I installed on it Ubuntu 12.04 LTS and I noticed that the overall system is very slow in responding. I tried to search about that in the internet and I found some articles talking about how to make Ubuntu 12.04 LTS run fast I applied all what they said including download LXDE desktop environment and then nothing different in the system response time. Then I need to develop some android applications so, I download Android Studio (Beta) 0.8.6. The problem became worse than before whenever I tried to open the Android Studio the screen is frozen for some minutes then it took time to download the projects and initialize the work space also, when I tried to move the cursor he is move very slowly. When I tried to run my first application on the AVD it took three hours and still not run yet. I delete the Android Studio and install it again several times, I was trying to solve the problem but still nothing change. Please if you have any suggestions that may help me make my laptop and Android Studio work faster I will appreciate it for you. Thank you in advance.

  • Troubleshooting my internet connection

    - by Simon Verbeke
    While I was out of the house, my father rearranged the network cables a bit. I don't know what he has done exactly - He says nothing more then pulling and untangling. When I came back home, my internet connection changed its IP from 192.168.0.205 to 169.254.197.233. The speed changed from 1Gbps to 10Mbps. It has also been at 100Mbps for a while. My subnetmask changed from 255.255.255.0 to 255.255.0.0. The standard gateway changed from 192.168.0.1 to no standard gateway. My DNS servers remain the same. I have checked the lights of the UTP ports, and it looks like it's only sending a heartbeat every few seconds. A sketch of the (relevant part of) the network: My PC ----- extender ----- modem ^ ^ ^ Wired | Wired | This thing connects two cables to each other All the cabling is gigabit, my network card is a Realtek RTL8168C(P)/8111(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20). THe modem is a CBN SVG6540E I have no idea what is going on here and I don't know how to find out either. Any help is welcome! If you need any more info, please ask.

  • Windows Vista/7 dropping Mac Server share points

    - by Hooligancat
    My Windows Vista and Windows 7 clients are having problems maintaining access to SMB shares on a Mac server. The initial connection to the server appears to be OK, as the Windows clients can see all of the server share points. However, the client randomly drops a couple of the server share points although the clients can still see the server. For example. If I have the following share points on the Mac server: Share A Share B Share C Share D Share E The Windows client can see these shares most of the time and can access them most of the time. But randomly a couple of the shares will just get dropped or go missing from the Windows client's ability to view them so I end up with something like: Share B Share D Share E All the share points are established int the same way with the same permission settings. My Mac OSX Server is set up with the following for SMB: SMB sharing enabled Standalone Server Workgroup of `CORPORATE` Allow Guest Access = YES Client connections limit = 100 Authentication: NTLMv2 & Kerberos and NTLM Code Page is Latin US (437) This is a workgroup master browser WINS registration is set to Enable WINS server (tried with setting off) Enable virtual share points for homes YES I noticed in my SMB file service log that the clients appear to connect OK, but I get the following error which implies a reset by either the server or the client: /SourceCache/samba/samba-187.9/samba/source/lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.0.99. = Connection reset by peer I am a bit stumped as to a direction to turn to try and get this to resolve. Continued attempts to access the server from the client will reconnect to the share points, but they inevitably get dropped again in the near future. Any and all help much appreciated.

  • How to setup ping between XP guest from Win8 Host using Hyper-V virtual swtich

    - by rism
    Hyper-V client is installed on a Win8 Pro 64 bit box and a VM running XP has been created within that with an internal virtual swtich. The VM can be booted and accessed and there is a default virtual NIC within it with dynamic IP of 169.254.x.x which i have changed to be a static IP of 192.168.0.12/255.255.255.0 confirmed via ipconfig on the XP guest. The Host has IP of 192.168.0.7/255.255.255.0. Both host and guest have their firewalls disabled for simplicity. I cant ping guest from host nor host from guest. TTL timeout. And with regard to Hyper-V and VMs I dont know what to do next. Both are in same workgroup (as per name) but since they cant ping I guess that means nothing. .... My objective is to share a folder on VM so I can install a 32bit accountancy app that wont run on Win8/7 so if there is a more simplistic way then Im all ears but typically a peer to peer is very simple.

  • Ubuntu server apt-get says "(-5 - No address associated with hostname)"

    - by Srini
    I have a ubuntu 12.04 server. Running sudo apt-get update on it produces errors like this: W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/precise-backports/main/binary-i386/Packages Something wicked happened resolving 'au.archive.ubuntu.com:http' (-5 - No address associated with hostname) I am able to ping all the other hosts on the network and also Google's DNS 8.8.8.8. But am unable to ping www.google.com. So, I'm guessing something is wrong with my DNS setup, but not sure what. I use static IP and my /etc/network/interfaces looks like this: auto eth0 iface eth0 inet static address 192.168.1.50 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.0.255 gateway 192.168.1.1 #dns-nameserver 203.12.160.35 203.12.160.36 #nameserver 203.12.160.35 203.12.160.36 My /etc/resolv.conf and /etc/resolvconf/resolv.conf.d/base are both empty and my /etc/resolvconf/resolv.conf.d/original says: nameserver 192.168.1.1 Any help would be greatly appreciated. P.S. I've googled it a bit and the common resolution is to switch to DHCP which I don't want to do since this is my home server. Thanks Srini
