  • Server 2012 file server security - File access through software only?

    - by user1607914
    I have just setup a server 2012 essentials R2 box as a test bed for my small business. Its running Essentials R2 as a VM on a Essentials R2 host. I have set it up to be the DC and DHCP server and joined a client. My next task is to use it as a file server but I am not quite sure how to set it up. All the client interactions with the file server will be through client side software. I therefore do not want any access to the files apart from through the software. I have looked at the ntfs permissions and there is a permission called "List Folder/Read Data" however I am unsure this will do what I want. Is it possible to give access to the files but not allow access through the windows explorer / command line?

  • Server 2008 R2 file access permissions

    - by Napster100
    I'm finding it awkward to sort out permissions for file sharing and access on my LAN. I've created an account on the server node (as a normal user) and shared a drive that has 2 folders at the root, one is for personal file storage and the other shared files, if I connect to the shared area from a workstation running windows 7 and log-in using the account I created on the server, I can look through directories but can't look in some (which I wanted as I changed the permissions for that to happen), but my problem is although the permissions are set for this user account to have full control of the specific folder I can't create a folder in that area or upload files to that folder. Could someone explain why this is? Thanks in advanced

  • close file with fclose() but file still in use

    - by Marco
    Hi all, I've got a problem with deleting/overwriting a file using my program which is also being used(read) by my program. The problem seems to be that because of the fact my program is reading data from the file (output.txt) it puts the file in a 'in use' state which makes it impossible to delete or overwrite the file. I don't understand why the file stays 'in use' because I close the file after use with fclose(); this is my code: bool bBool = true while(bBool){ //Run myprogram.exe tot generate (a new) output.txt //Create file pointer and open file FILE* pInputFile = NULL; pInputFile = fopen("output.txt", "r"); // //then I do some reading using fscanf() // //And when I'm done reading I close the file using fclose() fclose(pInputFile); //The next step is deleting the output.txt if( remove( "output.txt" ) == -1 ){ //ERROR }else{ //Succesfull } } I use fclose() to close the file but the file remains in use by my program until my program is totally shut down. What is the solution to free the file so it can be deleted/overwrited? In reality my code isn't a loop without an end ; ) Thanks in advance! Marco Update Like ask a part of my code which also generates the file 'in use'. This is not a loop and this function is being called from the main(); Here is a piece of code: int iShapeNr = 0; void firstRun() { //Run program that generates output.txt runProgram(); //Open Shape data file FILE* pInputFile = NULL; int iNumber = 0; pInputFile = fopen("output.txt", "r"); //Put all orientations of al detected shapes in an array int iShapeNr = 0; int iRotationBuffer[1024];//1024 is maximum detectable shapes, can be changed in RoboRealm int iXMinBuffer[1024]; int iXMaxBuffer[1024]; int iYMinBuffer[1024]; int iYMaxBuffer[1024]; while(feof(pInputFile) == 0){ for(int i=0;i<9;i++){ fscanf(pInputFile, "%d", &iNumber); fscanf(pInputFile, ","); if(i == 1) { iRotationBuffer[iShapeNr] = iNumber; } if(i == 3){//xmin iXMinBuffer[iShapeNr] = iNumber; } if(i == 4){//xmax iXMaxBuffer[iShapeNr] = iNumber; } if(i == 5){//ymin iYMinBuffer[iShapeNr] = iNumber; } if(i == 6){//ymax iYMaxBuffer[iShapeNr] = iNumber; } } iShapeNr++; } fflush(pInputFile); fclose(pInputFile); } The while loop parses the file. The output.txt contains sets of 9 variables, the number of sets is unknown but always in sets of 9. output.txt could contain for example: 0,1,2,3,4,5,6,7,8,8,7,6,5,4,1,2,3,0

  • How to use more than 3 virtual disks in Linux using CentOS and XenServer

    - by 010110110101
    I've attached 5 virtual disks to a Virtual Machine in Citrix XenServer. The VM has the xs-tools installed. Initially it said that it couldn't add so many disks. After I installed the xs-tools, it let me add all the disks. But /dev doesn't show all the disks. It shows these: /dev/xvda /dev/xvdb /dev/xvdc /dev/cdrom Perhaps it is bound by the limits of an IDE bus? (3 disks + CD-ROM) If so, how does one change the VM to use SCSI? Edit: According to the documentation: 2.6.3. VM Block Devices In the PV Linux case, block devices are passed through as PV devices. XenServer does not attempt to emulate SCSI or IDE, but instead provides a more suitable interface in the virtual environment in the form of xvd* devices. It is also possible to get an sd* device using the same mechanism, where the PV driver inside the VM takes over the SCSI device namespace. This is not desirable so it is best to use xvd* where possible for PV guests (this is the default for Debian and RHEL). For Windows or other fully virtualized guests, XenServer emulates an IDE bus in the form of an hd* device. When using Windows, installing the Citrix Tools for Virtual Machines installs a special PV driver that works in a similar way to Linux, except in the fully virtualized environment. Still, with 5 virtual disks attached, I don't see the other xvd devices.

  • `:Zone.Identifier` files keep on appearing in Windows XP virtual machine

    - by Jonathan Reno
    I have a Windows XP Home Edition guest and a Linux Mint 13 host. I use VirtualBox and the ~/Public directory is shared with the guest. It sometimes happens that I use IE on the guest system to download files (until I get a better Windows browser). All of the downloaded files go the the L:\ drive (the ~/Public directory). When they are finished downloading, Windows Explorer adds a :Zone.Identifier file for each file I download. When I extract a downloaded ZIP archive on the guest (on drive L:\), Windows creates a :Zone.Identifier file for every file in the extracted directory. This even occurs if I use the host to move a file to the ~/Public directory. The shared ~/Public directory is on an ext4 partition and the colon character is supposed to be illegal in file names in Windows, but not on the ext4 partition. Is there any way to stop Windows from putting all this rubbish on my filesystem? (I might have to create a shell script to clean up after Windows' act.) Here is what I see in Windows Explorer: By the way, if I were running a Mac OS X host (where colons are illegal file name characters) this would be even more horrendous.

  • Flat File Connection Manager in SSIS package shows "Valid File Name Must be Selected"

    - by Traples
    (Flat File Location) Samba Share | Windows Share (SSIS) _______________________________ | | XP 32bit | Works | Works | | 2003 Serv 32bit | Works | Works | | Vista 64bit | ERROR | Works | | Win 7 64bit | ERROR | Works | | 2008 Serv 64bit | ERROR | Works I created an SSIS package in VS 2008 that parses a flat file from a shared folder and puts the records into a SQL Server db. I recently installed Windows 7 and VS 2008 on a new workstation. When I import the package from TFS and open it, I get the error Validation error. Parse and Import Catalog Flat File: MySSISPackage: The file name "\\shared\flatfile.txt" specified in the connection was not valid. When I open the Flat File Connection Manager Editor, there is an error stating: A valid file name must be selected I can browse to and select the file from inside the editor, but I cannot change any properties, or move away from the General tab because of this error. If I go back to my laptop (Windows XP), where the package was first created, there is no error. Both workstations are on the same domain, and I'm logging in using the same credentials. Any ideas as to why I would receive this error from one workstation and not another? UPDATE: If I take the .dtsx package from the running workstation and load it into SSIS on the server, I get the following errors when it tries to run: Error: The file name "\\shared\flatfile.txt" specified in the connection was not valid. and... Error: Connection "MySSISPackage" failed validation. and... Error: The file name property is not valid. The file name is a device or contains invalid characters. UPDATE 2: a) The Shared folder I'm trying to pull the flat file from is a Samba share on a Unix box. b) If I access the file using SSIS on any 64-bit platform (Windows 7 64-bit, Vista 64-bit, Windows Server 2008) I get the error "A valid file name must be selected." c) Accessing the file using SSIS from 32-bit environments (Windows XP 32-bit, Windows Server 2003 32-bit) there is no problem. d) If I move the file to a shared folder on a Windows server, 64-bit SSIS recognizes the file.

  • Virtual PC on Windows 7 - Hardware-assisted virtualization is disabled

    - by DLux
    I am running a Lenovo Thinkpad T61 with an Intel Core 2 Duo T7300 processor. When I run Virtual PC in Windows 7, I get the following error: Unable to start Windows Virtual PC because hardware-assisted virtualization is disabled. When running the Hardware-Assisted Virtualization Detection Tool from Microsoft says: Hardware-assited virtualization is not enabled on this computer. Now, in the BIOS, I do have virtualization enabled and according to Intel this processor supports Intel-VT. What am I missing here?

  • IIS6 Virtual Directory 500 Error on Remote Share

    - by David
    We have our servers at the server farm in a domain. Let's call it LIVE. Our developer computers live in a completely separate corporate domain, miles and miles away. Let's call it CORP. We have a large central storage unit (unix) that houses images and other media needed by many webservers in the server farm. The IIS application pools run as (let's say) LIVE\MediaUser and use those credentials to connect to a central storage share as a virtual directory, retrieve the images, and serve them as if they were local on each server. The problem is in development. On my development machine. I log in as CORP\MyName. My IIS 6 application pool runs as Network Service. I can't run it as a user from the LIVE domain because my machine isn't (and can not be) joined to that domain. I try to create a virtual directory, point it to the same network directory, click Connect As, uncheck the "Always use the authenticated user's credentials when validating access to the network directory" checkbox so that I can enter the login info, enter the credentails for LIVE\MediaUser, click OK, verify the password, etc. This doesn't work. I get "HTTP Error 500 - Internal server error" from IIS. The IIS log file reports sc-status = 500, sc-substatus = 16, and sc-win32-status = 1326. The documentation says this means "UNC authorization credentials are incorrect" and the Win32 status means "Logon failure: unknown user name or bad password." This would be all and good if it were anywhere close to accurate. I double- and trouble-checked it. Tried multiple known good logins. The IIS manager allows me to view the file tree in its window, it's only the browser that kicks me out. I even tried going to the virtual directory's Directory Security tab, and under Authentication and Access Control, I tried using the same LIVE domain username for the anonymous access credential. No luck. I'm not trying to run any ASP, ASP.NET, or other dynamic anything out of the virtual directory. I just want IIS to be able to load static images, css, and js files. If anyone has some bright ideas I would be most appreciative!

  • How to specify file permission when putting a file using OpenSSH sftp command

    - by Adi Roiban
    I am using various SFTP clients for uploading files to an SFTP server and I have a problem with default permission used when putting files. When requesting to put a file, SFTP client like WinSCP or Filezilla will send the SSH_OPEN command without requesting any explicit file permission. On the other side, it looks like the OpenSSH sftp command on Linux (Red Hat and Ubuntu) is pending the SSH_OPEN command together with the '640' mode. How can I configure the OpenSSH command to not explictly set the file mode or how can I configure it to send a mode, other than 640? Many thanks! Update: I checked the OpenSSH sftp client source code and it looks like OpenSSH sftp will always tries to preserve file mode even if -P is not set: http://www.koders.com/c/fidD3B20680F615B33ACCB42398FAAFEE1C007DF942.aspx?s=rsa#L986 To solve this problem I used Putty SFTP client.

  • virtual appliance resources

    - by user11457
    I'm fairly new to appliances but have become a big fan of virtualization. Are there any other resources where I can find and download virtual appliances outside of vmware's website? Or do I just need to scour the web looking them? I'm sure there is a central site that lists all the virtual appliances available, if there isn't I'm going to write one.

  • Can GPU capabilities impact virtual machine performance?

    - by Dave White
    While this many not seem like a programming question directly, it impacts my development activities and so it seems like it belongs here. It seems that more and more developers are turning to virtual environments for development activities on their computers, SharePoint development being a prime example. Also, as a trainer, I have virtual training environments for all of the classes that I teach. I recently purchased a new Dell E6510 to travel around with. It has the i7 620M (Dual core, HyperThreaded cpu running at 2.66GHz) and 8 GB of memory. Reading the spec sheet, it sounded like it would be a great laptop to carry around and run virtual machines on. Getting the laptop though, I've been pretty disappointed with the user experience of developing in a virtual machine. Giving the Virtual Machine 4 GB of memory, it was slow and I could type complete sentences and watch the VM "catchup". My company has training laptops that we provide for our classes. They are Dell Precision M6400 Intel Core 2 Duo P8700 running at 2.54Ghz with 8 GB of memory and the experience on this laptops is night and day compared to the E6510. They are crisp and you barely aware that you are running in a virtual environment. Since the E6510 should be faster in all categories than the M6400, I couldn't understand why the new laptop was slower, so I did a component by component comparison and the only place where the E6510 is less performant than the M6400 is the graphics department. The M6400 is running a nVidia FX 2700m GPU and the E6510 is running a nVidia 3100M GPU. Looking at benchmarks of the two GPUs suggest that the FX 2700M is twice as fast as the 3100M. http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html 3100M = 111th (E6510) FX 2700m = 47th (Precision M6400) Radeon HD 5870 = 8th (Alienware) The host OS is Windows 7 64bit as is the guest OS, running in Virtual Box 3.1.8 with Guest Additions installed on the guest. The IDE being used in the virtual environment is VS 2010 Premium. So after that long setup, my question is: Is the GPU significantly impacting the virtual machine's performance or are there other factors that I'm not looking at that I can use to boost the vm's performance? Do we now have to consider GPU performance when purchasing laptops where we expect to use virtualized development environments? Thanks in advance. Cheers, Dave

  • Virtual Function Implementation

    - by Gokul
    Hi, I have kept hearing this statement. Switch..Case is Evil for code maintenance, but it provides better performance(since compiler can inline stuffs etc..). Virtual functions are very good for code maintenance, but they incur a performance penalty of two pointer indirections. Say i have a base class with 2 subclasses(X and Y) and one virtual function, so there will be two virtual tables. The object has a pointer, based on which it will choose a virtual table. So for the compiler, it is more like switch( object's function ptr ) { case 0x....: X->call(); break; case 0x....: Y->call(); }; So why should virtual function cost more, if it can get implemented this way, as the compiler can do the same in-lining and other stuff here. Or explain me, why is it decided not to implement the virtual function execution in this way? Thanks, Gokul.

  • Shared block device file system (cluster file system without networking)

    - by fungs
    Is there any file system that can be mounted multiple times and supports concurrent file access for Linux? Basically I want something like a cluster file system but without the need to have a running network for a distributed lock manager. That can be very handy in connection with virtual machines that can share data with the host or another VM without the need to create a network link. This I want to avoid to keep the network architecture secure (virtual machine in DMZ) but share large files. No need to scale it up, just two machines that mount the same block device. Shouldn't it be possible to have file locking information right on the disk?

  • Two dimensional virtual desktop space in Ubuntu

    - by Herms
    Is there any way to create a 2-dimensional virtual desktop space in Ubuntu? The only control I'm seeing is the number of virtual desktops, but they seem to only go in a line. I'm used to having a 2-dimensional space (so I can go up/down/left/right instead of just left/right), and I'd really like to have that in ubuntu as well.

  • Windows Server 08 R2 file share File locking, OSX clients

    - by Keith Loughnane
    I've spent the last two weeks banging my head against this wall. I think I'm starting to understand the problem though. I manage a design company and they have 5 macs (OSX 10.5/.6/.7) connected over SMB to a Windows 2008 R2 file server, another machine functions as Domain Controller (that might not matter). All the macs can connect ok, no issues finding the server or logging in. For the most part things are ok. The problem is files locking up. I thought it was a permissions issue at first but it seems to be file locking. The users open a file; .ind, .pdf etc the file opens, the software reads it and closes it. That's fine, but the folder above the folder locks, it can't be moved and it can't be renamed. Eg: /Working/Project01/Imagefiles/image.pdf /Finished/ The user opens image.pdf, closes it and wants to move the whole Project01 folder into Finished. It gives a username/pass dialogue and then does nothing, no error, or just does nothing. Trying to rename gives a dialogue that says you don't have permission. It looks like it's looking for permission locally, which is why I spent about a week looking at that. Eventually I found that Finder on the macs seems to be keeping the folders open. I can work around it by Killing finder, remounting the shared drive or closing the file through the server manager but this just proves the theory it's not a solution. Has anyone dealt with this problem?

  • CMD Command to create folder for each file and move file into folder

    - by Tom
    I need a command that can be run from the command line to create a folder for each file (based on the file-name) in a directory and then move the file into the newly created folders. Example : Starting Folder: Dog.jpg Cat.jpg The following command works great at creating a folder for each filename in the current working directory. for %i in (*) do md "%~ni" Result Folder: \Dog\ \Cat\ Dog.jpg Cat.jpg I need to take this one step further and move the file into the folder. What I want to achieve is: \Dog\Dog.jpg \Cat\Cat.jpg Can someone help me with one command to do all of this?

  • CMD file time not always matching windows explorer file time

    - by skyrail
    I have a set of file I need to set the created, modified and last access date to exif date taken value, after a copy between 2 folders (might be fat32 on memory card or ntfs on fixed or usb disk). When I copy a file, the date and time switch to the current date. Then I change all 3 dates manually, either with change attributes in windows explorer or far manager on the command line. To make it faster I wrote a batch script getting original file dates (with php and function stat), building a batch script that invoke nircmd setfiletime for each file. Then I apply this batch to the copied version. The operation is relatively fast and reliable. Unfortunately, a bunch of files have last access and created time different in cmd and windows explorer (1H difference). Very strangely, it happens with dates between november and february, which make the operation unreliable. Why is this happening, and how can I fix it?
