  • TrueCrypt with blank password

    - by TheSavo
    This might sound like an odd question, but please hear me out. I want to setup my laptop to use TrueCrypt, but without a password. My wife doesn't travel much with her notebook. There are occasions where we will have to travel and bring the notebook with us. This is when we would like the have the encryption. The time it takes to to change the unlock pass-phrase is considerably less than it takes to encrypt the drive. My thoughts are to leave the disk encrypted but with no password. Then when it's time to pack for a trip and bring the laptop, we would then change the pass-phrase and create a rescue disk.

  • Hyper-V stuck restoring VM

    - by Blax
    I have a hyper-v server that runs 5 virtual machines. I believe the physical box rebooted last night which is usually not a problem but this morning one of the virual machines is stuck at "restoring 0%". I have rebooted the physical machine and same thing, 4 virtual machines come up fine the 5th gets stuck at "restoring 0%". I right-clicked the VM in hyper-v manager and selected "Cancel restore" and nothing happens. I was able to copy the VHD to another hyper-v box and light it up there so I know the VHD is good. Any ideas on what to look at next? If I can I would like to just dump the saved state and move on, or if there is a better way to handle it I'm all ears. TIA!!

  • Super slow time machine backup on my mac

    - by lowellk
    I just got a new 2TB drive which I'm trying to use as a time machine drive for my mac which has a 1TB drive. On my first time trying to back it up, I'm getting terrible throughput, not even 1GB per day (it's been running for 36 hours now). I erased the disk and tried to copy a large file to it and got the same slow speed. What can I do to diagnose this? Are there any tools which can inspect the disk and tell me if it's messed up? Thanks!

  • Small footprint on a Laptop

    - by sqldebacle
    I am trying to find a solution where I can do the following: 1) Run a small footprint on my laptop 2) Run virtual instances of OS w/ no primary OS installed. All the OS that I will ever use will be all virtualized. I tried playing around with the VMware Esxi, and got it to boot it from the flash drive, etc. But this just runs the server. I cannot actually run my virtual instances from there. Anyone has done this? Something similar implemented with VMWare products without needing 2 computers will be great. Thanks, -Subhash

  • Mac webcam photo application with access to camera settings (resolution, camera selection, color balance, focus)

    - by Pascal T.
    Does anyone know about a webcam photo application (ie an alternative to photo booth) with would allow to change the settings on the camera, such as : Select camera (I.e I want to use an external webcam) Change camera resolution (with photobooth change camera settings (I.e autofocus, aperture, color balance, etc..) I did a lot of research on the internet with no success. I am looking for a very simple app (such as wmcap.exe on Windows) What I tried so far: photo booth: it works with an external camera, however there is no way to change the resolution, or the color/focus settings manycam : a virtual webcam driver. you can add special effects to your camera and transfer those effects to any app, but not change your camera settings... iGlasses : enables you to change the camera settings inside photo booth and other apps. However you cannot control the focus, nor the video resolution macam (did not work on my Mac book Pro) Does anyone know better than me? Note : my only solution now is to launch a virtual machine (with parallels desktop) and take the pictures from there!

  • It's the ethernet 10/100 in LAN transfer faster than USB 1.0?

    - by dag729
    I have an old laptop (PIII 800MHz, with 256 RAM) that I wish to use as my home server: it'll have to serve just two people, so I think that I'll be more than ok as for the RAM and the CPU. The issue is about data, because the internal hard disk is a 12GB, that is...ridicolous! I have more than 60GB of mixed storage and counting (images, videos and music) in an external usb hd. I could put the hd in my desktop pc just to serve the big files through ethernet or let it inside its usb box attached to the laptop. The question is: which of these solutions will be the fastest? USB 1.0 attached to the server (laptop) or internal hard disk serving files via 10/100 ethernet to the laptop on demand?

  • Windows screen resolution change: lengthen timeout

    - by Jonathan J
    Occasionally I need to change the screen resolution of the console of a Windows virtual machine using XenCenter. When you attempt this change, Windows will revert if you don't accept the changed resolution within 15 seconds of clicking 'apply.' (Normally, this is a good thing.) The problem is that if I have a slow connection between XenCenter and the Xen hypervisor, the virtual console display may not refresh quickly enough to allow me to respond within 15 seconds. As a result, I can't change the resolution, even though the new resolution is valid. Is there a way to increase the timeout before reverting to the original display resolution?

  • Windows 2008 Server on VMWare (hardware)

    - by Bill
    I want to setup a single server to run a few virtual servers for our datacenter. I do not have a lot of money to spend so I am trying to gain bang for the buck. My budget is around $2,000. So I was thinking about building the following as the VMWare physical server: Intel iCore 7 950 (LGA1366, 4 cores,8 threads) Gigabyte GA-X58-USB3 LGA 1366 X58 ATX Intel Motherboard 24 GB of Viper II Series, Sector 7 Edition, Extreme Performance DDR3-1600 (PC3-12800) CL9 Triple Channel Memory VelociRaptor 300GB 10,000 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive I am planning on running the newest version of VMWare ESXi (64-bit). On these I am planning on running a few various servers: Windows 2008 Server R2 w/ IIS (several custom built ASP.NET Apps) Windows 2008 Server R2 w/ MS SQL 2008 Database Server Linux Web Server w/ Several WordPress Blogs (XAMPP?) Windows 2008 Server R2 w/ IIS (DEV ENVIRONMENT) Windows 2008 Server R2 w/ MS SQL 2008 Database Server (DEV ENVIRONMENT) In your opinion, will this hardware be sufficient to run the above load with room for possible 2-3 more virtual machines (probably lightweight web servers)?

  • PostgreSQL 9.0 HA load balancing between servers

    - by Vijay Ramachandran
    Hey folks, I'm bashing my head to configure load balancing stuff between two database servers. I have no clue whether, I can find any mechanism to implement this. I already tried to implement Heart beat clustering but it requires virtual Ip wherein I can't create virtual IP or assign my own IP address in amazon EC2. Is there a way to configure PostgreSQL database servers in similar to Amazon load balancing kind of thing ? If so, please suggest the solution. Thanks in advance.

  • Would there be any problems with DEP turned off?

    - by IneedHelp
    I recently moved to a fresh Windows 8 x64 system and I learned that my favourite firewall (JPF - Jetico Personal Firewall) doesn't get along with Win8x64 (CRITICAL_STRUCTURE_CORRUPTION errors), but I can not do without JPF, so I kind of tried everything I could think of (test mode, debugging, various system changes), but I was still getting blue screens because of the firewall driver/software. I know for sure that it is the firewall that is causing the problems because I get blue screens as soon as I install it and they stop when I uninstall it. I Also tested it thoroughly on virtual computers. Anyway, I have discovered that by completely turning DEP off by using this command: bcdedit.exe /set {current} nx AlwaysOff the firewall would not cause blue screens anymore. So my question is, what could go wrong with DEP completely turned off? Note: I do not care much about hardware/windows security, I keep myself secured by using sandboxes and virtual computers (and I also have backups), so I'm not concerned with viruses and root kits or whatever people are freaking out about.

  • What router hardware or software should be used when multiple public IPs are routed into the same LAN?

    - by lcbrevard
    I am looking for recommendations to replace a set of consumer grade (Linksys, Netgear, Belkin) routers with something that can handle more traffic while routing more than one static public IP into the same LAN address space. We have a block of static public IPs, 5 usable, with Comcast Business. Currently four of them are in use for: General office access Web server Mail and DNS servers Download and backup web server for separate business All systems (a mixture of physical and virtual) are in the same LAN address space (10.x.y.0/24) to enable easy access between them inside the office. There are 30 or more systems in use depending on which virtual machines are currently active. We have a mixture of Windows, Linux, FreeBSD, and Solaris. Currently a separate consumer grade router is used for each of the four static addresses, with its WAN address set to the specific static address and a different gateway address for each: uses 10.x.y.1 - various ports are forwarded to various LAN IPs on systems with gateway 10.x.y.1 uses 10.x.y.254 - port 80 is forwarded to a server with gateway 10.x.y.254 uses 10.x.y.253 - ports for mail and dns are forwarded to a server with gateway 10.x.y.253 uses 10.x.y.252 - ports as needed are forwarded to server with gateway 10.x.y.252 Only router 1. is allowed to serve DHCP and address reservation based on the MAC is used for most of the internal "server" IP addresses so they are at fixed values. [Some are set static due to limitations in the address reservation capabilities of router 1.] And, yes, this really does work! But... I am looking for: better DHCP with more capable address reservation higher capacity so I don't have to periodically power cycle the routers One obvious improvement would be to have a real DHCP server and not use a consumer grade router for that purpose. I am torn between buying a "professional" router such as Cisco or Juniper or Sonic Wall verus learning to configure some spare hardware to perform this function. The price goes up extremely rapidly with capabilities for commercial routers! Worse, some routers require licensing based on the number of clients - a disaster in our environment with so many virtual machines. Sorry for such a long posting but I am getting tired of having to power cycle routers and deal with shifting IP addresses afterwards!

  • Configuring bridged network connection --- Windows 7 host, Ubuntu 10.04 guest --- VMWare Workstation 8

    - by H3br3wHamm3r81
    Here is my IPCONFIG /ALL from the host (Windows 7 64-bit): Here is my IFCONFIG from the guest (Ubuntu 10.04): To be honest, I don't have experience configuring a network between a host and a guest in VMWare (a virtual machine). I've searched high and low on the internet, but I haven't seen anything that can help. Perhaps I'm just not using the right keywords when I search. Nevertheless, does anyone here have any experience with establishing a network connection? Edit: One important note. I don't use DHCP to provide private addresses to the hosts on my LAN. I use "static" IP addresses on my internal network by configuring each IP address manually in the host's network configuration utility (I have TV's, XBOX 360, and a few PC's). I would like to configure the IP on the virtual machine guest manually as well. The reason is because my XBOX 360 only works properly using a static IP address. It will kick me off XBOX Live if it has one given by the router (via DHCP).

  • Network Path not found while joining Active Directory

    - by Chiggins
    So I have an Amazon EC2 box running Windows Server 2008 with Active Directory installed on it. I also have a Windows 7 virtual machine, which is set to use the Active Directory box as its DNS and WINS server. I'm trying to join the virtual machine to the domain, and I'm asked for authentication. I give authentication, wait a minute, and I get an error saying: The following error occurred attempting to join the domain "ad.chigs.me": The network path was not found. How can I fix this so that I'll be able to join the domain? Thanks!

  • Installing Solaris 10 on sunT5220 - ZFS/UFS raid 10?

    - by Matthew
    I am in a bit of a time crunch, and need to get two T5220's built. We were very happy to see two boxes in our aged inventory which had 8 HDD's each, but didn't think to check if they were running hardware RAID or not. Turns out that they aren't. When we install, we are given the option to use UFS or ZFS, but when we select a place to install we're only given the option of installing on one single disk. Is it possible to create a software raid 10 across all of the disks and install the OS on that? Sorry if any lingo is wrong, I'm not really a Sun guy and our guru is out of town right now. Any help would be really appreciated! Note: Most of the guides I've found on google entail installing the OS on a single disk, and then creating a separate RAID 10 on other disks. We would actually like the OS to reside on the RAID 10. Hope that clarifies things.

  • Robocopy to copy only new folders and files

    - by Valery Shampal
    A task: To find all new files and subfolders under some root folder (let us say Documents) and to copy them to other disk (j: in this case) Command line used: robocopy c:\users\valery\documents j:\robocopy /XO /E /MAXAGE:20131030 /XD Result: A full folders tree created. Only new files copyed, as supposed. It's good A point is, that I do not want to create all subfolders on a target disk, if there are no new files in them. Results are exeptable, but there is a lot of work to go through all folders and to find new files, as well, as to understand, what subfolders are a new ones Regards, Valery

  • Hyper-V Ubuntu Networking Problems Copying Large Amounts of Data

    - by Anonymous
    I am trying to copy a large amount (about 50 GB) of data over my network from a Hyper-V-hosted virtual machine running Ubuntu 11.04 (Natty Narwhal) to another (non-virtual) Ubuntu host that I plan to use for testing upgrades to one of our web applications. The problem I am having is with the virtual machine, which I shall refer to in what follows as "source.host". This machine is running 64-bit Ubuntu Server with the 2.6.38-8-server kernel and the Microsoft Linux Integration Components for Hyper-V kernel modules (hv_utils, hv_timesource, hv_netvsc, hv_blkvsc, hv_storvsc, and hv_vmbus) loaded. It uses a Hyper-V "synthetic network adapter" for its networking interface. To do the copy, I log on to the machine with the data and run the following commands (Call the remote machine "destination.host".): $ cd /path/to/data $ tar -cvf - datafolder/ | ssh [email protected] "cat > ~/data.tar" This runs for a while and then suddenly stops after transferring somewhere from 2-6 GB. The terminal on the source.host machine displays a Write failed: broken pipe error. The odd part is this: after this occurs, the "source.host" machine is no longer able to talk to the rest of the network. I cannot ping any other hosts on the network from the "source.host" machine, and I cannot ping the "source.host" machine from any other host on the network. I am equally unable to access the any of the web services hosted on "source.host". Running ifconfig on "source.host" shows the network adapter to be up and running as usual with the correct IP address and everything. I tried restarting the networking service with $ /etc/init.d/networking restart but the problem does not go away. Restarting the machine makes it capable of talking to the network again -- it can ping and be pinged by other hosts, and the web services are also accessible and usable as normal -- but attempting the copy operation again results in the same failure, requiring another restart. As an experiment, I tried replacing the tar -- ssh pipeline above with a straight scp: $ scp -r datafolder/ [email protected]:~ but to no avail Thinking that the issue might have to do with the kernel packet-send buffers filling up, I tried increasing the buffer size to 12 MB (up from the 128 KB default) with # echo 12582911 > /proc/sys/net/core/wmem_max but this also had no effect. I'm guessing at this point that it might be a problem with the Microsoft synthetic network driver, but I don't really know. Does anyone have any suggestions? Thank you very much in advance!

  • VirtualBox: Grub sees hard drive, Linux does not

    - by thabubble
    I installed Linux on my second hard drive. I can boot to it just fine. But when I try to boot it from a Windows 7 host using http://www.virtualbox.org/manual/ch09.html#rawdisk, grub sees it and can load vmlinuz and initramfs. Log: :: running early hook [udev] :: running hook [udev] :: Triggering uevents... :: running hook [plymouth] :: Loading plymouth...done. ... Waiting 10 seconds for device /dev/disk/by-uuid/{root UUID} ... ERROR: device 'UUID={root UUID}' not found. Skipping fsck. ERROR: Unable to find root device 'UUID={root UUID}' It then drops me into a recovery shell. I checked "/etc/fstab" and it's empty, there are also no sd* devices in dev, the only thing in /dev/disk/by-id is a VBox CD device. I'm not too good with these kinds of things so help would be greatly appriciated.

    I just bought a 48GB SSD express card for my laptop and I am trying to decide how best to use it. I will be running some sort of virtualization (prob VirtualBox) to test / learn Windows Server administration. I am running Windows 7 Ultimate 64 bit. I have 4GB of RAM and a 7200 RPM SATA hard disk. The express card will read at 115MB/s and write at 65MB/s. So how best to use this new disk? Readyboost, relocate pagefile, store VM disks, mix / match?

  • USB Format Error

    - by Dan Finan
    I'm having a real headache trying to reformat a USB drive. Initially it had a 200mb EFI partition and it caused the drive to disappear altogether. Since then I ran the CMD and wiped the disk using 'diskpart'. It took a few attempts but it finally cleaned the drive. Since then it has reappeared under (:E) however I am unable to access the drive and Windows is preventing me from reformatting it. I am just presented with 'Windows was unable to complete the format'. It's now acting like a CD drive instead of removable storage. I've tried going through Disk Management and I'm presented with the same error. I've removed the USB controllers from Device Manager - when the drive is connected again it re-installs the drivers and acts the same way. Any help given will be greatly appreciated, thank you. (Windows 7 machine)

  • Deleted All Snapshots, Now Won't Boot VM with Snapshot not found error

    - by Jharwood
    I've just tried deleting the snapshots from this virtual machine running ESXI5, so that I can grow the Thick Partition. I've now got the below error message when I try to start the VM, the VM also can't be grown above 0 MB i assume for the same reason as below. I've checked the datastore and the original VMDK is still there. Reason: The system cannot find the file specified. Cannot open the disk 'VM1-PG-000002.vmdk' or one of the snapshot disks it depends on. VMware ESX cannot find the virtual disk "VM1-PG-000002.vmdk". Verify the path is valid and try again. How do i tell ESXI5 to use the proper VMDK?

  • How can I tell if my live web-server is overloaded?

    - by Nick G
    We have a live webserver which doesn't seem to be performing all that well. It's a Dell PowerEdge machine, a few years old (dual core, 4GB) which is hosting about 20 low-traffic websites. However it doesn't seem to be as fast as it used to be. How can we determine the cause of this? If it's website traffic, I would be expecting high CPU but CPU usage is quite low and hovers around the 15-30% mark except for very brief periods. I'm wondering perhaps, if rather than CPU performance being a problem, perhaps it's disk thrashing due to the constant read/writes of all the small web files and database queries. It has 4x 7200 RPM SATA drives in RAID 5. So is there a way to check that it's not disk thrashing?

  • Using an Internal HDD as an External HDD also or an External HDD for installing SAP ?

    - by Asterix
    Is it possible and advisable to use an Internal Hard Drive as an External Hard drive also. I wanted to install SAP ECC 6 on my system which has only 250 GB but atleast 300 GB is required.I wanted to buy an External Drive first, then I heard loading SAP on an External would make it extremely slow. I'll be using it only as a beginer so even if it is a little slow i don't mind. Is it feasible to run such a big application from an External Hard disk ? So can i purchase a 500 or 1 TB Internal Hard disk and use it as an External too by fitting it with the necessary USB 3.0 Hard drive cases and cables ? or should i purchase a External and load SAP onto it ? Thank you.
