  • Automounting Active Directory home drives on a Linux server on login

    - by Ethan
    I've got a Centos 5.7 box authenticating against Active Directory through PBIS Open (the new LikeWise Open), which works well. Now, I'm trying to get the server to automount the user's AD home directory, located at //ad.server.dom/shares/home directories (Yeah, it's a space in the path. I didn't set this up). Each user has a directory in there with the same name as the user. I've tried to get pam_mount working, but it has a series of issues on RedHat and friends, and I can't seem to get that working. The directory does need to be automounted for the server to perform it's role. My reading on automount seems to suggest that there's no way to get it to do it's thing with authentication, though I'm happy to be proved wrong. I've looked at this resource, but it requires version RedHat (thus CentOS) 6 or higher, and newer packages than I have. I can manually (As root) mount the AD directory using the command mount.cifs "//ad.server.dom/Shares/home directories/testuser" /home/local/AD/testuser/nfs_mount/ -o username=testuser and when I log in as testuser, I can see all of the sample files in the nfs_share directory. Any tips towards the right direction would be highly appreciated. This is going to be on a server at a college, so it needs to be fairly stable, and would lead towards more Linux adoption there.

  • How to rotate a group of objects around a common center?

    - by user1662292
    I've made a model in 3D Studio Max 9. It consists of a variety of cubes, clyinders etc. In XNA I've imported the model okay and it shows correctly. However, when I apply rotation, each component in the model rotates around it's own centre. I want the model to rotate as a single unit. I've linked the components in 3D Max and they rotate as I want in Max. protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); model = Content.Load<Model>("Models/Alien1"); } protected override void Update(GameTime gameTime) { camera.Update(1f, new Vector3(), graphics.GraphicsDevice.Viewport.AspectRatio); rotation += 0.1f; base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); Matrix[] transforms = new Matrix[model.Bones.Count]; model.CopyAbsoluteBoneTransformsTo(transforms); Matrix worldMatrix = Matrix.Identity; Matrix rotationYMatrix = Matrix.CreateRotationY(rotation); Matrix translateMatrix = Matrix.CreateTranslation(location); worldMatrix = rotationYMatrix * translateMatrix; foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.World = worldMatrix * transforms[mesh.ParentBone.Index]; effect.View = camera.viewMatrix; effect.Projection = camera.projectionMatrix; effect.EnableDefaultLighting(); effect.PreferPerPixelLighting = true; } mesh.Draw(); } base.Draw(gameTime); } More Info: Rotating the object via it's properties works fine so I'm guessing there's something up with the code rather than with the object itself. Translating the object also causes the objects to get moved independently of each other rather than as a single model and each piece becomes spread around the scene. The model is in .X format.

  • MVC and delegation

    - by timjver
    I am a beginning iOS programmer and use the Model-View-Controller model as a design pattern: my model doesn't know anything about my view (in order to make it compatible with any view), my view doesn't know anything about my model so they interact via my controller. A very usual way for a view to interact with the controller is through delegation: when the user interacts with the app, my view will notify my controller, which can call some methods of my model and update my view, if necessary. However, would it make sense to also make my controller the delegate of my model? I'm not convinced this is the way to go. It could be handy for my model to notify my controller of some process being finished, for example, or to ask for extra input of the user if it doesn't have enough information to complete the task. The downside of this, though, is that my controller would be the delegate for both my controller and my model, so there wouldn't be really a proper way to notify my model of changes in my view, and vice versa. (correct me if I'm wrong.) Conclusion: I don't really think it's a good idea to to have my controller to be the delegate of my model, but just being the delegate of my view would be fine. Is this the way most MVC models handle? Or is there a way to have the controller be the delegate of both the controller and the model, with proper communication between them? Like I said, I'm a beginner, so I want to do such stuff the right way immediately, rather than spending loads of hours on models that won't work anyway. :)

  • Check if file is locked or catch error for trying to open

    - by Duncan Matheson
    I'm trying to handle the problem where a user can try to open, with an OpenFileDialog, a file that is open by Excel. Using the simple FileInfo.OpenRead(), it chucks an IOException, "The process cannot access the file 'cakes.xls' because it is being used by another process." This would be fine to display to the user except that the user will actually get "Debugging resource strings are unavailable" nonsense. It seems not possible to open a file that is open by another process, since using FileInfo.Open(FileMode.Open, FileAccess.Read, FileShare.ReadWrite) chucks a SecurityException, "File operation not permitted. Access to path 'C:\whatever\cakes.xls' is denied.", for any file. Rather unhelpful. So it's down to either finding some way of checking if the file is locked, or trying to catch the IOException. I don't want to catch all IOExceptions and assume they're all locked file errors, so I need some sort of way of classifying this type of exception as this error... but the "Debugging resource strings" nonsense along with the fact that that message itself is probably localized makes it tricky. I'm partial trust, so I can't use Marshal.GetHRForException. So: Is there any sensible way of either check if a file is locked, or at least determining if this problem occurred without just catching all IOExceptions?

  • Open closed prinicple, problem

    - by Marcus
    Hi, I'm trying to apply OCP to a code snippet I have that in it's current state is really smelly, but I feel I'm not getting all the way to the end. Current code: public abstract class SomeObject {} public class SpecificObject1 : SomeObject {} public class SpecificObject2 : SomeObject {} // Smelly code public class Model { public void Store(SomeObject someObject) { if (someObject is SpecificObject1) {} else if (someObject is SpecificObject2) {} } } That is really ugly, my new approach looks like this: // No so smelly code public class Model { public void Store(SomeObject someObject) { throw new Expception("Not allowed!"); } public void Store(SpecificObject1 someObject) {} public void Store(SpecificObject2 someObject) {} } When a new SomeObject type comes along I must implement how that specific object is stored, this will break OCP cause I need to alter the Model-class. To move the store logic to SomeObject also feels wrong cause then I will violate SRP (?), becuase in this case the SomeObject is almost like a DTO, it's resposibility it not how to know to store itself. If a new implementation to SomeObject comes along who's store implementation is missing I will get a runtime error due to exception in Store method in Model class, it also feels like a code smell. This is because calling code will in the form of IEnumerable<SomeObject> sequence; I will not know the specific types of the sequence objects. I can't seem to grasp the OCP-concept. Anyone has any concrete examples or links that is a bit more than just some Car/Fruit example?

  • Open new UserControl in the mainWindows

    - by user287964
    Hi I have this snippet public partial class Window1 : Window { public Window1() { InitializeComponent(); } private void ToggleButton_Checked(object sender, RoutedEventArgs e) { switch ((sender as Button).Content.ToString()) { case "UserControl 1": AddItemToContainer(new UserControl1()); break; case "UserControl 2": AddItemToContainer(new UserControl2()); break; case "UserControl 3": AddItemToContainer(new UserControl3()); break; default: break; } } void AddItemToContainer(UIElement _myElement) { Grid.SetColumn(_myElement, 1); HostContainer.Children.Add(_myElement); } } } } With this I can open a new userControl in myMainwindow Let’s say something like adding child to myMainWinodw,Now I’m trying to click on a button from my userControl so I open another userControl that take the place of the first one I explain: I have the mainWindows it has 3 button first one to open the first UserControl the second one to open the second userControl and the third to open the last UserControl,imagine that I opened the first UserControl let’s call it UC1, In the UC1 I have a button to open the second userControl (let’s call it UC2) I like that when I clik the button from the UC1 the UC2 is opened and take the place of the UC1 (of course the UC2 is still a child of myMainWinodw) I have alredy try to call the AddItemToContainer methode from other methode but nothing is happened Any suggestion please

  • qemu-img: Could not open $FILE

    - by HTTP500
    I received a single-file VMDK from a vendor that has a virtual appliance for a particular product I'm interested in evaluating. We run a KVM solution (Proxmox) so I tried converting the file but on that system qemu-img blows up. (I was able to convert (multipart) VMDK files from bitnami without error.) So I figured I'll just yum install qemu-img on a RHEL 6.3 VM and do it there. But despite the fact that I can file the file just fine when I run qemu-img on it I get this error that it can't open the file: [root@host dir]# file 1.vmdk 1.vmdk: VMware4 disk image [root@host dir]# qemu-img info 1.vmdk qemu-img: Could not open 'vmdk' I've seen some other people post on the interwebs that they've had this problem but none of them seem to have a resolution. Does anyone have any ideas? I have checked the MD5SUM already. EDIT1: [root@host dir]# qemu-img info -f vmdk 1.vmdk qemu-img: Could not open '1.vmdk' EDIT2: Ran strace per suggestion. Not sure what to look for... Here is a possible: ioctl(3, CDROM_DRIVE_STATUS, 0x7fffffff) = -1 ENOTTY (Inappropriate ioctl for device)

  • Explorer and open file dialog not responding (Vista)

    - by rohancragg
    Any explorer window opened for the first time on my machine causes the explorer window to display the folders tree and folder path in the address bar immediately but the file/folder list pane is blank and the window displays 'Not Responding' in the title bar, this hangs for up to a minute or more. Any file dialog displays 'Not Responding' in the title bar. The files list is eventually displayed after a few seconds or more. Steps to repro: Close all open instances of explorer Windows Key | Run | [enter a folder path such as 'c:\temp'] Or within any app: use a file open / save dialog Once there is at least one open instance of explorer the performance is still fairly poor but not nearly so bad and file lists are displayed in a timely fashion. What I've tried: Cleaned up registry with CCleaner tool, and uninstalled all other unused software Checked nothing unwanted running at startup with Autoruns Removed any ISO burner/recorder/mount software Still to try Get latest version of everything - especially stuff with shell extension behaviour such as TortoiseSVN Anyone have any other suggestions? Thanks alot. Update I'm wondering if this is related, I'll try the hotfix when I get home and report back: KB972685 - FIX:Explorer.exe hangs when using a shell extension written using MFC Update 2 Before I got a chance to try the hotfix it seems one of the above actions fixed this for me; either the removal of IsoRecorder or TortoiseHg (which I was no longer using anyway). Update 3 A similar issue with Explorer.exe has come back since installing TortoiseHg 1.01 :-(

  • Free or Open Solution for Storing and Charting CSV data

    - by rrrfusco
    I'm presently storing CSV files, combining them, opening them in open office, creating pivot tables and then generating charts from the spreadsheet. I've looked at OOBase, but appending csv files to base is clunky for some reason. SQLite seems like a good database solution, but I've haven't found a good charting program that connects to it with ease. Although open office (or libreoffice) maintains the references and allows you to update the information, this process is far from efficient. There are too many steps and it seems one program should handle all of these tasks. A better program would be more intuitive, allow you to simply add inserts into a database, and include an interface for standard charting settings. EDIT Simplest Automated Analysis and Chart Generation Tool? The above answer references Spotfire and Tableau, each of which has a free 14 and 30 day trial. Each program is nicely streamlined and designed. I'm looking for a program between this quality and LibreOffice. Can you recommend a better open or free desktop solution for windows?

  • Windows file locks allowing multiple users to write to open file over network

    - by JPbuntu
    I have 6 windows computers (xp,vista,7) that need to access a samba share (Ubuntu 12.04). I am trying to make it so only one client can open a file at a given time. I thought this was pretty standard behavior of file locks, but I can't get it to work. The way it is right now a file can be open by two users, and changed and saved by either one of them. The last file saved overwrites what ever changes the other user made. At first I thought this was a Samba configuration problem, but I get this behavior even between two windows machines. So far I have only tested: Windows Xp Windows Vista Windows XP Samba << Windows Vista and both give the same behavior. When I tested the Samba configuration, I had set strict locking = yes and get errors logged like this: close_remove_share_mode: Could not get share mode lock for file _prod/part_number_list_COPY.xlsx Eventually all of the files are going to be moved onto the Samba share, so that is the configuration I am most concerned about fixing. Any ideas? Thanks in advance. EDIT: I tested an excel file again, and it is now working properly in both above mentioned cases, I am also no longer getting the above mentioned error. I don't know what happened, perhaps a restart fixed it? (also works with strict locking = no) Although I still need to find a solution for the CAD/CAM files we use, the software is Vector and it does not seem to be using file locks. Is there any software that I can use to manage these files, so two people can't open/edit them at a time? Maybe a windows application that forces file locks? Or a dirt simple version control system? (the only ones I have seen at are too complicated for our needs).

  • some windows 8 metro (modern UI) apps don't open, but live tiles DO work

    - by DiegoDD
    Some of my default windows 8 metro (modern UI) apps don't work properly, the apps are the Weather and the News apps. when I open them, I only get the loading screen, that is, the big colorful screen with the logo in the center, and the "loading" spinning dots. They just keep like that forever and never actually open. There are no error messages or anything. The strange this is that the live tiles for those apps DO work and show current information. current weather for my location (saved before they started failing) and current news. Both apps did work well in the past, and every other default windows 8 app I've tried work well (both live tiles and the app itself). Every other non-default apps that I've downloaded still work correctly, so the problem so far is only with those two apps. (weather and news). I really don't know since when exactly they started to fail because I really don't use them (or any metro app) that often, so I can't recall if I did something like installing some other app, either metro or regular, or messed with some drivers, etc. they simply don't open now, but they DID work before. any ideas?

  • Mac SMB connections to Windows 2003 server, leaving Open Files

    - by Bruce Garlock
    We have several Mac clients (Both 10.5, and 10.6) mounting a share from a Windows 2003 server. At least once a day, our archivist will go into this share to archive items from it, to the backup server. Most of the time, she has no issues: she copies the folder to the archive server, when it's done, she deletes it from this share. Then, she will come upon one, and it will say she doesn't have permission. When I go into the Open sessions, it will say that a particular user has a READ lock on the file, in Windows 2003. Of course, this person does not have the file open, and the only way we can delete it, is to close the open session on the file. My thoughts: The Mac likes to "sprinkle" Hidden "Resource Forks" on SMB servers, and possibly, when this Mac who last wrote to that share, closes out of the file, and these files still exist. Windows 2003 has a bug, that doesn't properly "release" the OPLOCK on the file? Steve Ballmer just doesn't like Mac's, so he wants to annoy everyone by not releasing file locks :-) What can be done about this? It happens every day, and sometimes several times per day! Many thanks, Bruce

  • .lnk doesn't open, no errors

    - by MushinNoShin
    I have a shortcut (.LNK) on my desktop to a MS Access database out on a network drive. When I double click that shortcut I get an hour glass for about 10 seconds and then nothing. No errors, no access opening, nothing happens. It appears as if there's not even an MSAccess process running in the background. The file successfully opens from: The Open dialog in Access The commandline "C:\path\to\MSACCESS.EXE C:\path\to\shortcut.lnk" The commandline "C:\path\to\MSACCESS.EXE C:\path\to\whatTheShortcutPointsTo.mdb" The file silently fails to open from: Double clicking the shortcut.lnk Double clicking the mdb file that shortcut.lnk targets At first I thought it had to do with how the link handler operated but the fact that it does the same exact thing when I try to open the mdb directly in explorer makes me think it's an issue with explorer. I've tried restoring, deleting, and recreating the association with the extension. I've tried running MSACCESS.EXE /regserver. I've run out of things to throw at it. In case this is specific to MS Access 2007; I'm trying to use 2007 :)

  • Windows 7 Synchronize folders BUT while some files are open

    - by Nick
    I need some way to synchronize 2 drives I have. I want to do this ofter (once a day or so) There is the main drive that I want to clone/synchronize on a backup hard disk. The problem is in that there is an open TrueCrypt file mounted as a drive, and its live. If you don't know what true crypt is, basically you create a file on a hard disk and that file is encrypted. It's constantly open and modified live. Also Its pretty large. 100GB + I will use freefilesync . There are many tools that can do that. My question is, is it safe to copy the encrypted file while its open ? Does the software freeze the file in one state and copies it ? Or will I get a corrupted file on the other drive ? It was not clear to me how windows handles that. I read something about shadow copy, and the software says that it supports this. Does anyone know something on the matter that can help me ? or some software that will work ok in my scenario ? Thanks
