• Why do I have only incoming traffic when copying from network source to network destination?

  - by mxp

  I have a VirtualBox VM that is located on a network share of my NAS. When I copy something from the VM's disk onto another of the NAS' network shares (so the data is visible outside the VM), the Windows 7 Task Manager shows only incoming network traffic (yellow graph). It's as if the data was only received but never sent over the network. I verified that the data arrives on the other network share. As I understand it, the data flow looks like this: +-NAS--------+ +-Win7 PC (VM Host)-+ | Share1(VM)-|>---->|-+ | | | | | | | Share2 <---|<----<|-+ | +------------+ +-------------------+ If it was like this, I would see incoming and outgoing traffic, right? What am I not getting here?

• Fedora Core 11 won't boot without a monitor

  - by feihtthief

  I have a P4 system that I installed Fedora 11 on. It will not boot without a monitor attached. The monitor can be off (not even have power plugged in), but must be attached. Without a monitor the hard disk thrashes around a bit like it's starting up services, but does not get to the point where I can ssh into the box. I have set the default runlevel to 3 and removed the rhgb entry from grub. Any suggestions welcome. Edit: I have already set the run-level to 3. The machine boots up fine with the monitor plugged in to the point where I can SSH into it. as soon as i unplug the monitor and reboot, it will not boot to that point.

• Raid on ICH9R chip set

  - by user500982

  Hi Im looking at buyign this MB: http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPE-HF-D525.cfm Im wondering though if the chipset will support the raid configuration I need. Im looking to configure the following arrays: raid array 1: 2 2TB Disks in Raid 0 raid array 2: 2 2TB Disks in Raid 0 raid array 3 (not actualy an array): 1 300GB Disk not in raid, to be used for OS and boot. So in total there would be 5 drives and the board supports 6. so im good when it comes to connections. However I have herd some chip sets only support one raid array (volume). so either all drives are individual, or are in the array. I must have 2 sperate raid arrays independent of each other, and a 5th drive not in any array. Anybody know if this setup will work? Thanks, -Stewart

• Do I need to retain Sharepoint usage analysis log files

  - by dunxd

  Our Sharepoint installation currently has 30Gb of Usage Analysis Log file - these date back about six months. I have configured Sharepoint to do Usage Analysis Processing every night, so I am wondering whether I need to keep these files for so long. Sharepoint doesn't seem to clean up these files automatically - I think six months ago I had to clear out logs due to disk space issues. So my question is, do I need to retain these files in order to get decent usage analysis reports, or can I delete them as soon as the usage analysis processing has completed?

• Common filesystem for servers behind a rackspace load balancer

  - by thanos panousis

  Our PHP application consists of a single web server that will receive files from clients and perform a CPU-intensive analysis on them. Right now, analysis of a single user upload can take 3sec to conclude and take 100% CPU. This makes our system capacity amount to 1/3 requests per second. My team's requirement is to increase capacity without a lot of code reengineering. A possible solution would be to set up a load balancer in front of multiple servers running the same app, connecting to a common DB. The problem is that the analysis outputs files on disk. A load balancer would increase capacity, but then files won't be available between servers so consequent client requests may fail. We are hosted on Rackspace, is there a way to configure some sort of "common" storage for all servers, without having to rewrite our file persistance code? Current code relies on simple fopens etc. What are our options?

• IE10 does not open .pdf

  - by user203298

  I can't open any PDFs in IE10 on Win7 64bit. I've tested with PDFs from Intranet / Internet / local file system, http and https. I've tested installing/uninstalling Acrobat Reader 11.0.03 and the Nitro PDF Reader. I've also tried enabling/disabling the Tools Internet Options Advanced Security Do not save encrypted pages to disk option. In Google Chrome PDFs are opened in the Acrobat Reader Plugin, but in IE10 the only thing I always get is a small cross in the top left corner of the browser. Can anybody help me?

• Windows Azure virtual machine credentials

  - by Georges

  I have created a Windows Server virtual machine, and this also automatically created a disk (VHD). Then I removed the vm, and I created a new vm from the same vhd: in this process I wasn't asked to supply any credentials. I am not able anymore to login (with rdp) to the new VM, the credentials that I supplied when creating the first machine don't work anymore. Any ideas why this happens? What credentials should I use? Thanks a lot in advance.

• Computer Locks Up Completely When Resuming From Standby

  - by kcoppock

  Okay, so I'm having a strange issue lately with my desktop, and off the top of my head I'm not sure what the problem is, so I'm hoping for some ideas on how to track down the cause. First, my PC: AMD Phenom 9600 Quad-Core 2.4 GHz 4 GB DDR2 160 GB boot HDD 1 TB & 120 GB secondary HDD Nvidia GeForce 8600 GTS Windows 7 Professional 64-bit I have my power settings as follows: Turn off the display: 10 minutes Turn off hard disk: 20 minutes Sleep after: Never After a while, I'll come back to use my computer again, wiggle the mouse, and the screen comes back on like normal, but the desktop is unresponsive. I can move the cursor, but nothing responds to clicks or keyboard entry. If I click a few times with the mouse, the computer eventually locks up completely and the mouse cursor stops moving as well. After I restart, everything works just fine. Is there a log you recommend checking or really any suggestions would be welcome at this point. Thanks!

• difference between server and desktop

  - by user1241438

  I want to set up a webserver. I would like to buy a hardware for that and i am trying to understand if i should buy a desktop and host the webserver on that or do i have to buy some used server from ebay and host on it. Example is http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180986172861&ssPageName=ADME:X:RTQ:US:1123 But what is the difference in desktop and server? These days even desktops are coming with high RAM. Only other difference i see is servers have RAID HARD disk. Is there any other difference?

• How to find spyware dll launched using svchost.exe

  - by Sheen

  This weekend I found my PC was possibly infected by some virus or spyware. There is one "svchost.exe -k netsvcs" in my task manager, and it is running under my user name, rather than SYSTEM accounts. There is already another same process with same command line options under SYSTEM account. This user account svchost.exe consistently consumes 50% CPU (1 of 2 cores of my CPU). In Process Explorer, I can see it is started by explorer.exe, instead of services.exe. However, I failed to find its real service dll place in registry or disk. Does anyone know how to find this malicious program?

• Problem reinstalling GRUB

  - by DisgruntledGoat

  I have a PC that dual-boots Ubuntu and Windows Vista. I recently reinstalled Windows Vista after some problems and now the bootloader's gone. I've been trying to follow this Ubuntu community guide but it's not working. I have Grub Legacy according to the first part (I installed Ubuntu 9.04 originally then upgraded). From the 9.04 LiveCD, I ran this: sudo grub-install --root-directory=/media/disk /dev/sda5 sda5 is the Ubuntu partition. I get this output: grub-probe: error: Cannot open `/boot/grub/device.map` [: 494: =: unexpected operator Installing GRUB to /dev/sda5 as (hd0,4)... Installation finished.No errors reported. This is the contents...(etc) (hd0) /dev/sda In the bit below, when I run setup (hd0) I get an error, "Error 17: Cannot mount selected partition" Little help?

• Activating Windows 7 generates error code 0xc004F061

  - by Jon

  I got a new SSD and wanted to start over with Windows 7 on that disk. I did a clean install (my mistake) on the SSD and just went passed the activation part (left the key blank). Now that I have my system all setup, configured, files pulled back from backup, and ready to go, I'd like to activate Windows 7. However, I now get this error: The following failure occurred while trying to use the product key: Code: 0xC004F061 Description: The Software Licensing Service determined that this specified product key can only be used for upgrading, not for clean installations. Do I really need to wipe my system again, install Windows Vista, and then do the Windows 7 upgrade in order to use my upgrade key? Is there some kind of work around?

• Does ZFS cache Compressed or Uncompressed data in a ZFS file-system with compression turned on?

  - by George Bailey

  ZFS supports file-system compression and it also caches frequently or recently accessed data. If a system has lots of CPU but the underlying data storage system is slow. It is possible that ZFS would perform better with compression turned on. This can be easily tested when writing files by measuring CPU and disk usage and throughput. (of course latency may exist,, but this would not be an issue for large files). But what about cache? If data will have to be decompressed every time it is read then this is probably less of a good idea. Is the cached data compressed?. Does anybody have some information on this?

• Which built-in account is used for Anonymous Authentication in IIS 7?

  - by smwikipedia

  We know that Microsoft IIS 7.0 offer a slew of authentication methods such as Anonymous Authentication, Form Based Authentication, Digest Authentication, etc. I read from Professional IIS 7 published by Wrox that: When we use Anonymous Authentication, the end-user does not supply credentials, effectively mak- ing an anonymous request. IIS 7.0 impersonates a fixed user account when attempting to process the request (for example, to read the file off the hard disk). So, what is the fixed user account impersonated by IIS? Where can I see it? If I don't know what this account is, how could I assign proper permissions for the clients who are authenticated as anonymous users? Thanks.

• Reinstall Windows on mass computers

  - by user791022

  At work there are about 40 DELL PC's - half of them are Windows Vista and other half are Windows 7. Some of the DELL PC's are 220s and 230s model. If I want to re-install Windows then I can use a Recovery/Recovery disk on any Dell PC's (220s or 230s). It take too long to complete the setup, for example - after re installing the Windows then I need to install the drivers, update windows, install IE9, create default users account and so on. It take about 3 hour to complete setup! I am looking for a solution Where I can create an Image of windows (with driver and completed setup) and then I use same Image it on any PC's at work? If one of the PC need reinstalling - I would like to reinstall via network (LAN) by grabbing the Image? Is there something that before booting into windows - computer check something via network which can download the Image?

• Feeding the kernels entropy source from other machines and/or increasing its maximum size

  - by David Spillett

  We have has a little trouble with a small box that acts as a VPN end-point and mail relay for our network, caused by the available entropy for /dev/random being too low (which causes TLS connection attempts by exim to fail). The machine doesn't do anything else, so the normal feed into the entropy pool (interrupt timings from things like disk access) is not enough. As a quick hack I've set a looping script that reads from /dev/hda at a couple of Mbyte/sec which keeps it topped up. Other than buying a hardware RNG, is there a clean way of piping data for entry from elsewhere, such as a copy of the data our file server uses for its entropy source? I've spotted several tips for using rng-tools to feed it from /dev/urandom on the same machine but that "feels dirty". Also, is it possible to increase the maximum pool size? It currently seems to max out at 3585.

• Downloaded chm is blocked, is there a solution?

  - by David Rutten

  CHM files that are downloaded are often tagged as potentially malicious by Windows, which effectively blocks all the html pages inside of it. There's an easy fix (just unblock the file after you download it), but I was wondering if there's a better way to provide unblocked chm files. What if I were to download the chm file (as a byte stream) from our server inside the application, then write all the data to a file on the disk. Would it still be blocked? Is there another/better way still? Edit: Yes, downloading the file using a System.Net.WebClient does solve the problem. But, is there still a better way?

• Create a web interface that starts VM's on the server side

  - by xdragonforce

  I am creating a service called TorCompute which allows for creating virtual Tor Hidden Service servers on my infrastructure (I say infrastructure, by that I mean just the 3x 32GB RAM machines waiting to be purchased). What I would like to be able to do is for users to log on, access the web interface and spin up a VM with a variable about of RAM/Disk Space. I've written the PHP for logging in and have a nice web interface, just I need the code to actually create them! How would I go about doing this? Thanks, Stewart EDIT: I will run them with VMWare Server, with vmrun

• Deleted entire harddisk. Now my laptop won't boot anything and stuck at grub rescue

  - by Jahan

  My laptop is Dell Inspiron N4030. I used to use Ubuntu 12.04 and it was on the entire hard drive. I tried to install windows 7 but my laptop couldn't install it. So, I decided to delete the entire hard drive and do a fresh install of Windows 7. But after deletion I immediately removed the gparted live usb which I was using to delete the partitions of my hard drive. And then tried booting from windows 7 cd, didn't work, tried ubuntu live cd, didn't work, tried hiren's boot cd, didn't work, tried super grub disk, didn't work. Probably I'm not doing it right. Help needed badly.

• Very slow Windows 7 on Thinkpad T61

  - by bogdanf

  I have a very strange problem with my fresh install of Windows 7 Profesional, 64bits on my Lenovo Thinkpad T61 : The overal performance is very slow, the disk is constantly spinning, even without any program running (after boot, no other programs installed). The boot process is very slow itself (4-5 minutes). I mention that the laptop was fine on XP until the upgrade. Thanks ! Additional info (as requested by the comments) : 2GB RAM Yes, I added all the manufacturer (Lenovo) drivers and updates (using the utility provided by Lenovo) Tried with both 32 and 64 bits editions. The 32 bits one is performing a little better, but not very usable either. The hdd has enough space (20 GB or so) The problem is still present on a fresh install, so no recycle bin emptying or unistall programs (there aren't any except plain 7) would help. I'm not a newbie, so no obvious causes are left unchecked

• 32 vs 64-bit software for same machine?

  - by GorillaSandwich

  What is the difference between 32 and 64-bit software? My understanding is that 64-bit can use more RAM, if it's available, because it has a larger address space for it. Is this correct? And, specifically: If I have a 64-bit operating system with lots of RAM, and I install, say, the 32-bit version of MySQL instead of the 64-bit version, will it be unable to use all the available RAM and therefore run slower than the 64-bit version might on the same machine (assuming RAM becomes the bottleneck before processing speed or disk access speed or whatever)? If I have a 32-bit operating system and I install a 64-bit piece of software on it, will it (probably) fail to run?

• Linux using the link command

  - by Xavier

  Here it goes. I have a folder that contains a not so large amount of space called /data/backup but I have been told that if I link that folder (/data/backup) to an even bigger folder area like /bigdata/backup for example, that I will be able to execute backups to the /data/backup folder because it will be just a link but the data will be seen in both folders and the latter one (/bigdata/backup) will contain the backup results but it will show on both folders and since the /bigdata/backup has far more disk space then the backup will no longer fail because of space problems in the /data/backup one. Is this true? Thanks Xav

• Problem opening password encrypted .docx file on Word 2003

  - by molecule

  Hi all, I am having a problem opening a .docx file on my Word 2003. I have installed the Compatibility pack for 2007 but when i try to open this particular file, I receive the error "Word experienced an error trying to open the file. Try these suggestions. 1. Check the file permissions for the document, 2. Make sure there is sufficient free memory and disk space, 3. Open the file with the Text Recovery converter. I do not think it is any of the errors as I am able to open it on a different PC with Word 2003 as well. I also do not have any issues opening any non-password encrypted .docx files. Has anyone experienced the same issue? Most posts on the internet relate to "open and repair" but as mentioned, I am able to open this file on another PC without any problems. Any advice is greatly appreciated. Thanks, George
