  • Why does my PowerShell script hang when called in PSEXEC via a batch (.cmd) file?

    - by Kev
    I'm trying to remotely execute a PowerShell script using PSEXEC. The PowerShell script is called via a .cmd batch file. The reason we do this is to change the execution policy, run the powershell script then reset the execution policy again: On the remote server do-tasks.cmd looks like: powershell -command "&{ set-executionpolicy unrestricted}" powershell DoTasks.ps1 powershell -command "&{ set-executionpolicy restricted}" The PowerShell script DoTasks.ps1 just does this for now: Write-Output "Hello World!" Both of these scripts live in c:\windows\system32 (for now) just so they're on the PATH. On the originating server I do this: psexec \\web1928 -u administrator -p "adminpassword" do-tasks.cmd When this runs I get the following response at the command line: c:\Windows\system32>powershell -command "&{ set-executionpolicy unrestricted}" and the script runs no further. I can't ctrl-c to break the script and I just see ^C characters, I can type input from the keyboard and the characters are echoed to console. On the remote server I see that PowerShell.exe and CMD.exe are running in Task Manager's Process tab. If I end these processes then control returns to the command line on the originating server. I have tried this with just a simple .cmd batch file with a @echo hello world and it works just fine. Running do-tasks.cmd on the remote server via an RDP session works ok as well. Why is my remote batch file getting stuck when executing via PSEXEC?

  • Enable VRFY verb in Exchange 2007

    - by m0sa
    Is there a way to enable the VRFY command on the Exchange server. I know this command is a security risk, but the server sits behind a firewall, and is not accessible from the internet. I would just use it as a in-box. The mail traffic would be forwarded from my home coded SMTP server, which would check for the existence of the exchange mailbox with the VRFY command. I only found this on the internet, but this is only for legacy versions of Exhange.

  • Adventures in MVVM &ndash; My ViewModel Base

    - by Brian Genisio's House Of Bilz
    More Adventures in MVVM First, I’d like to say: THIS IS NOT A NEW MVVM FRAMEWORK. I tend to believe that MVVM support code should be specific to the system you are building and the developers working on it.  I have yet to find an MVVM framework that does everything I want it to without doing too much.  Don’t get me wrong… there are some good frameworks out there.  I just like to pick and choose things that make sense for me.  I’d also like to add that some of these features only work in WPF.  As of Silveright 4, they don’t support binding to dynamic properties, so some of the capabilities are lost. That being said, I want to share my ViewModel base class with the world.  I have had several conversations with people about the problems I have solved using this ViewModel base.  A while back, I posted an article about some experiments with a “Rails Inspired ViewModel”.  What followed from those ideas was a ViewModel base class that I take with me and use in my projects.  It has a lot of features, all designed to reduce the friction in writing view models. I have put the code out on Codeplex under the project: ViewModelSupport. Finally, this article focuses on the ViewModel and only glosses over the View and the Model.  Without all three, you don’t have MVVM.  But this base class is for the ViewModel, so that is what I am focusing on. Features: Automatic Command Plumbing Property Change Notification Strongly Typed Property Getter/Setters Dynamic Properties Default Property values Derived Properties Automatic Method Execution Command CanExecute Change Notification Design-Time Detection What about Silverlight? Automatic Command Plumbing This feature takes the plumbing out of creating commands.  The common pattern for commands in a ViewModel is to have an Execute method as well as an optional CanExecute method.  To plumb that together, you create an ICommand Property, and set it in the constructor like so: Before public class AutomaticCommandViewModel { public AutomaticCommandViewModel() { MyCommand = new DelegateCommand(Execute_MyCommand, CanExecute_MyCommand); } public void Execute_MyCommand() { // Do something } public bool CanExecute_MyCommand() { // Are we in a state to do something? return true; } public DelegateCommand MyCommand { get; private set; } } With the base class, this plumbing is automatic and the property (MyCommand of type ICommand) is created for you.  The base class uses the convention that methods be prefixed with Execute_ and CanExecute_ in order to be plumbed into commands with the property name after the prefix.  You are left to be expressive with your behavior without the plumbing.  If you are wondering how CanExecuteChanged is raised, see the later section “Command CanExecute Change Notification”. After public class AutomaticCommandViewModel : ViewModelBase { public void Execute_MyCommand() { // Do something } public bool CanExecute_MyCommand() { // Are we in a state to do something? return true; } }   Property Change Notification One thing that always kills me when implementing ViewModels is how to make properties that notify when they change (via the INotifyPropertyChanged interface).  There have been many attempts to make this more automatic.  My base class includes one option.  There are others, but I feel like this works best for me. The common pattern (without my base class) is to create a private backing store for the variable and specify a getter that returns the private field.  The setter will set the private field and fire an event that notifies the change, only if the value has changed. Before public class PropertyHelpersViewModel : INotifyPropertyChanged { private string text; public string Text { get { return text; } set { if(text != value) { text = value; RaisePropertyChanged("Text"); } } } protected void RaisePropertyChanged(string propertyName) { var handlers = PropertyChanged; if(handlers != null) handlers(this, new PropertyChangedEventArgs(propertyName)); } public event PropertyChangedEventHandler PropertyChanged; } This way of defining properties is error-prone and tedious.  Too much plumbing.  My base class eliminates much of that plumbing with the same functionality: After public class PropertyHelpersViewModel : ViewModelBase { public string Text { get { return Get<string>("Text"); } set { Set("Text", value);} } }   Strongly Typed Property Getters/Setters It turns out that we can do better than that.  We are using a strongly typed language where the use of “Magic Strings” is often frowned upon.  Lets make the names in the getters and setters strongly typed: A refinement public class PropertyHelpersViewModel : ViewModelBase { public string Text { get { return Get(() => Text); } set { Set(() => Text, value); } } }   Dynamic Properties In C# 4.0, we have the ability to program statically OR dynamically.  This base class lets us leverage the powerful dynamic capabilities in our ecosystem. (This is how the automatic commands are implemented, BTW)  By calling Set(“Foo”, 1), you have now created a dynamic property called Foo.  It can be bound against like any static property.  The opportunities are endless.  One great way to exploit this behavior is if you have a customizable view engine with templates that bind to properties defined by the user.  The base class just needs to create the dynamic properties at runtime from information in the model, and the custom template can bind even though the static properties do not exist. All dynamic properties still benefit from the notifiable capabilities that static properties do. For any nay-sayers out there that don’t like using the dynamic features of C#, just remember this: the act of binding the View to a ViewModel is dynamic already.  Why not exploit it?  Get over it :) Just declare the property dynamically public class DynamicPropertyViewModel : ViewModelBase { public DynamicPropertyViewModel() { Set("Foo", "Bar"); } } Then reference it normally <TextBlock Text="{Binding Foo}" />   Default Property Values The Get() method also allows for default properties to be set.  Don’t set them in the constructor.  Set them in the property and keep the related code together: public string Text { get { return Get(() => Text, "This is the default value"); } set { Set(() => Text, value);} }   Derived Properties This is something I blogged about a while back in more detail.  This feature came from the chaining of property notifications when one property affects the results of another, like this: Before public class DependantPropertiesViewModel : ViewModelBase { public double Score { get { return Get(() => Score); } set { Set(() => Score, value); RaisePropertyChanged("Percentage"); RaisePropertyChanged("Output"); } } public int Percentage { get { return (int)(100 * Score); } } public string Output { get { return "You scored " + Percentage + "%."; } } } The problem is: The setter for Score has to be responsible for notifying the world that Percentage and Output have also changed.  This, to me, is backwards.    It certainly violates the “Single Responsibility Principle.” I have been bitten in the rear more than once by problems created from code like this.  What we really want to do is invert the dependency.  Let the Percentage property declare that it changes when the Score Property changes. After public class DependantPropertiesViewModel : ViewModelBase { public double Score { get { return Get(() => Score); } set { Set(() => Score, value); } } [DependsUpon("Score")] public int Percentage { get { return (int)(100 * Score); } } [DependsUpon("Percentage")] public string Output { get { return "You scored " + Percentage + "%."; } } }   Automatic Method Execution This one is extremely similar to the previous, but it deals with method execution as opposed to property.  When you want to execute a method triggered by property changes, let the method declare the dependency instead of the other way around. Before public class DependantMethodsViewModel : ViewModelBase { public double Score { get { return Get(() => Score); } set { Set(() => Score, value); WhenScoreChanges(); } } public void WhenScoreChanges() { // Handle this case } } After public class DependantMethodsViewModel : ViewModelBase { public double Score { get { return Get(() => Score); } set { Set(() => Score, value); } } [DependsUpon("Score")] public void WhenScoreChanges() { // Handle this case } }   Command CanExecute Change Notification Back to Commands.  One of the responsibilities of commands that implement ICommand – it must fire an event declaring that CanExecute() needs to be re-evaluated.  I wanted to wait until we got past a few concepts before explaining this behavior.  You can use the same mechanism here to fire off the change.  In the CanExecute_ method, declare the property that it depends upon.  When that property changes, the command will fire a CanExecuteChanged event, telling the View to re-evaluate the state of the command.  The View will make appropriate adjustments, like disabling the button. DependsUpon works on CanExecute methods as well public class CanExecuteViewModel : ViewModelBase { public void Execute_MakeLower() { Output = Input.ToLower(); } [DependsUpon("Input")] public bool CanExecute_MakeLower() { return !string.IsNullOrWhiteSpace(Input); } public string Input { get { return Get(() => Input); } set { Set(() => Input, value);} } public string Output { get { return Get(() => Output); } set { Set(() => Output, value); } } }   Design-Time Detection If you want to add design-time data to your ViewModel, the base class has a property that lets you ask if you are in the designer.  You can then set some default values that let your designer see what things might look like in runtime. Use the IsInDesignMode property public DependantPropertiesViewModel() { if(IsInDesignMode) { Score = .5; } }   What About Silverlight? Some of the features in this base class only work in WPF.  As of version 4, Silverlight does not support binding to dynamic properties.  This, in my opinion, is a HUGE limitation.  Not only does it keep you from using many of the features in this ViewModel, it also keeps you from binding to ViewModels designed in IronRuby.  Does this mean that the base class will not work in Silverlight?  No.  Many of the features outlined in this article WILL work.  All of the property abstractions are functional, as long as you refer to them statically in the View.  This, of course, means that the automatic command hook-up doesn’t work in Silverlight.  You need to plumb it to a static property in order for the Silverlight View to bind to it.  Can I has a dynamic property in SL5?     Good to go? So, that concludes the feature explanation of my ViewModel base class.  Feel free to take it, fork it, whatever.  It is hosted on CodePlex.  When I find other useful additions, I will add them to the public repository.  I use this base class every day.  It is mature, and well tested.  If, however, you find any problems with it, please let me know!  Also, feel free to suggest patches to me via the CodePlex site.  :)

  • "Unable to open MRTG log file" error with nagios and mrtg

    - by Simone Magnaschi
    We have a strange issue with our setup of icinga / nagios and mrtg. Icinga is working great and has no problem, it can monitor basically everything without issues. We setup mrtg to gather bandwith data from our routers and switches. MRTG is working fine: it stores the log data in the /var/www/mrtg/ directory and displays the graph data via web. We assume so MRTG is doing great. We tried to setup bandwidth checks in nagios: define service{ use generic-service ; Inherit values from a template host_name zywall-agora service_description ZYWALL AGORA TRAFFICO check_command check_local_mrtgtraf!/var/www/mrtg/x.x.x.x_2.log!AVG!1000000,2000000!5000000,5000000!1000 check_interval 1 ; Check the service every 1 minute under normal conditions retry_interval 1 ; Re-check every minute until its final/hard state is determined } Where /var/www/mrtg/x.x.x.x_2.log is the correct log path file. We keep on getting Unable to open MRTG log file error in the test result in icinga web interface. We tried everything: give ownership to user nagios or icinga to the log file give chmod 777 to the file try to copy the file in another directory and give it full permission Same error. The strange thing is that if we use the command that nagios generate in a bash session the command works like a charm: /usr/lib64/nagios/plugins/check_mrtgtraf -F /var/www/mrtg/x.x.x.x_2.log -a AVG -w 10,20 -c 5000000,5000000 -e 10 Result: Traffic WARNING - Avg. In = 17.9 KB/s, Avg. Out = 5.0 KB/s|in=17.877930KB/s;10.000000;5000000.000000;0.000000 out=5.000000KB/s;20.000000;5000000.000000;0.000000 We ran that command line as root, as user nagios and as user icinga and all three worked ok. We thought that the command that nagios perform maybe has something wrong in it, so we debugged nagios but we found out that the generated command from nagios is the same as above. Searching on google for these kind of problem returns only issues of systems where mrtg is not installed or issues with the wrong path to the log file, but these seems not to be our case. We are stuck, can somebody help?

  • Recover Data Like a Forensics Expert Using an Ubuntu Live CD

    - by Trevor Bekolay
    There are lots of utilities to recover deleted files, but what if you can’t boot up your computer, or the whole drive has been formatted? We’ll show you some tools that will dig deep and recover the most elusive deleted files, or even whole hard drive partitions. We’ve shown you simple ways to recover accidentally deleted files, even a simple method that can be done from an Ubuntu Live CD, but for hard disks that have been heavily corrupted, those methods aren’t going to cut it. In this article, we’ll examine four tools that can recover data from the most messed up hard drives, regardless of whether they were formatted for a Windows, Linux, or Mac computer, or even if the partition table is wiped out entirely. Note: These tools cannot recover data that has been overwritten on a hard disk. Whether a deleted file has been overwritten depends on many factors – the quicker you realize that you want to recover a file, the more likely you will be able to do so. Our setup To show these tools, we’ve set up a small 1 GB hard drive, with half of the space partitioned as ext2, a file system used in Linux, and half the space partitioned as FAT32, a file system used in older Windows systems. We stored ten random pictures on each hard drive. We then wiped the partition table from the hard drive by deleting the partitions in GParted. Is our data lost forever? Installing the tools All of the tools we’re going to use are in Ubuntu’s universe repository. To enable the repository, open Synaptic Package Manager by clicking on System in the top-left, then Administration > Synaptic Package Manager. Click on Settings > Repositories and add a check in the box labelled “Community-maintained Open Source software (universe)”. Click Close, and then in the main Synaptic Package Manager window, click the Reload button. Once the package list has reloaded, and the search index rebuilt, search for and mark for installation one or all of the following packages: testdisk, foremost, and scalpel. Testdisk includes TestDisk, which can recover lost partitions and repair boot sectors, and PhotoRec, which can recover many different types of files from tons of different file systems. Foremost, originally developed by the US Air Force Office of Special Investigations, recovers files based on their headers and other internal structures. Foremost operates on hard drives or drive image files generated by various tools. Finally, scalpel performs the same functions as foremost, but is focused on enhanced performance and lower memory usage. Scalpel may run better if you have an older machine with less RAM. Recover hard drive partitions If you can’t mount your hard drive, then its partition table might be corrupted. Before you start trying to recover your important files, it may be possible to recover one or more partitions on your drive, recovering all of your files with one step. Testdisk is the tool for the job. Start it by opening a terminal (Applications > Accessories > Terminal) and typing in: sudo testdisk If you’d like, you can create a log file, though it won’t affect how much data you recover. Once you make your choice, you’re greeted with a list of the storage media on your machine. You should be able to identify the hard drive you want to recover partitions from by its size and label. TestDisk asks you select the type of partition table to search for. In most cases (ext2/3, NTFS, FAT32, etc.) you should select Intel and press Enter. Highlight Analyse and press enter. In our case, our small hard drive has previously been formatted as NTFS. Amazingly, TestDisk finds this partition, though it is unable to recover it. It also finds the two partitions we just deleted. We are able to change their attributes, or add more partitions, but we’ll just recover them by pressing Enter. If TestDisk hasn’t found all of your partitions, you can try doing a deeper search by selecting that option with the left and right arrow keys. We only had these two partitions, so we’ll recover them by selecting Write and pressing Enter. Testdisk informs us that we will have to reboot. Note: If your Ubuntu Live CD is not persistent, then when you reboot you will have to reinstall any tools that you installed earlier. After restarting, both of our partitions are back to their original states, pictures and all. Recover files of certain types For the following examples, we deleted the 10 pictures from both partitions and then reformatted them. PhotoRec Of the three tools we’ll show, PhotoRec is the most user-friendly, despite being a console-based utility. To start recovering files, open a terminal (Applications > Accessories > Terminal) and type in: sudo photorec To begin, you are asked to select a storage device to search. You should be able to identify the right device by its size and label. Select the right device, and then hit Enter. PhotoRec asks you select the type of partition to search. In most cases (ext2/3, NTFS, FAT, etc.) you should select Intel and press Enter. You are given a list of the partitions on your selected hard drive. If you want to recover all of the files on a partition, then select Search and hit enter. However, this process can be very slow, and in our case we only want to search for pictures files, so instead we use the right arrow key to select File Opt and press Enter. PhotoRec can recover many different types of files, and deselecting each one would take a long time. Instead, we press “s” to clear all of the selections, and then find the appropriate file types – jpg, gif, and png – and select them by pressing the right arrow key. Once we’ve selected these three, we press “b” to save these selections. Press enter to return to the list of hard drive partitions. We want to search both of our partitions, so we highlight “No partition” and “Search” and then press Enter. PhotoRec prompts for a location to store the recovered files. If you have a different healthy hard drive, then we recommend storing the recovered files there. Since we’re not recovering very much, we’ll store it on the Ubuntu Live CD’s desktop. Note: Do not recover files to the hard drive you’re recovering from. PhotoRec is able to recover the 20 pictures from the partitions on our hard drive! A quick look in the recup_dir.1 directory that it creates confirms that PhotoRec has recovered all of our pictures, save for the file names. Foremost Foremost is a command-line program with no interactive interface like PhotoRec, but offers a number of command-line options to get as much data out of your had drive as possible. For a full list of options that can be tweaked via the command line, open up a terminal (Applications > Accessories > Terminal) and type in: foremost –h In our case, the command line options that we are going to use are: -t, a comma-separated list of types of files to search for. In our case, this is “jpeg,png,gif”. -v, enabling verbose-mode, giving us more information about what foremost is doing. -o, the output folder to store recovered files in. In our case, we created a directory called “foremost” on the desktop. -i, the input that will be searched for files. This can be a disk image in several different formats; however, we will use a hard disk, /dev/sda. Our foremost invocation is: sudo foremost –t jpeg,png,gif –o foremost –v –i /dev/sda Your invocation will differ depending on what you’re searching for and where you’re searching for it. Foremost is able to recover 17 of the 20 files stored on the hard drive. Looking at the files, we can confirm that these files were recovered relatively well, though we can see some errors in the thumbnail for 00622449.jpg. Part of this may be due to the ext2 filesystem. Foremost recommends using the –d command-line option for Linux file systems like ext2. We’ll run foremost again, adding the –d command-line option to our foremost invocation: sudo foremost –t jpeg,png,gif –d –o foremost –v –i /dev/sda This time, foremost is able to recover all 20 images! A final look at the pictures reveals that the pictures were recovered with no problems. Scalpel Scalpel is another powerful program that, like Foremost, is heavily configurable. Unlike Foremost, Scalpel requires you to edit a configuration file before attempting any data recovery. Any text editor will do, but we’ll use gedit to change the configuration file. In a terminal window (Applications > Accessories > Terminal), type in: sudo gedit /etc/scalpel/scalpel.conf scalpel.conf contains information about a number of different file types. Scroll through this file and uncomment lines that start with a file type that you want to recover (i.e. remove the “#” character at the start of those lines). Save the file and close it. Return to the terminal window. Scalpel also has a ton of command-line options that can help you search quickly and effectively; however, we’ll just define the input device (/dev/sda) and the output folder (a folder called “scalpel” that we created on the desktop). Our invocation is: sudo scalpel /dev/sda –o scalpel Scalpel is able to recover 18 of our 20 files. A quick look at the files scalpel recovered reveals that most of our files were recovered successfully, though there were some problems (e.g. 00000012.jpg). Conclusion In our quick toy example, TestDisk was able to recover two deleted partitions, and PhotoRec and Foremost were able to recover all 20 deleted images. Scalpel recovered most of the files, but it’s very likely that playing with the command-line options for scalpel would have enabled us to recover all 20 images. These tools are lifesavers when something goes wrong with your hard drive. If your data is on the hard drive somewhere, then one of these tools will track it down!

  • Windows 7 + Deep Freeze - I'm stuck in an endless reboot loop

    - by myermian
    I have the following setup: Windows 7 Ultimate Deep Freeze I "thawed" my machine last night and performed a Windows Update. The update is having issues (it gets stuck at 32%, fails, and restarts my machine). When it reboots it attempts it again, and again, and again, etc. (Endless loop). I looked online and found some solutions, but none of them seem to be working: When I run Safe Mode, Safe Mode w/ Network, or Safe Mode w/ Command Prompt it attempts to revert the Windows Update changes. However, the problem is with Deep Freeze on (and now in "Frozen" mode) the reverted changes don't stay, and I'm back into the loop of death. Oh, and side note: "Safe Mode w/ Command Prompt" does not actually take me to a command prompt window? Perhaps because it is attempting to complete the Windows Update changes first? I have tried to select the option to NOT restart when an windows error occurs, but it still does. I tried the remainder of all the other options in the F8 screen. The only other option left is to find my Windows 7 Media Disc (I can't find it right now) and use it to repair windows (because for some reason the repair option does not show up in the F8 screen). Is there a way to disable Deep Freeze from loading? When I selected "Safe Mode w/ Command Prompt" I noticed that it loads the DpFrz.sys file. I know that when I'm in the Windows Boot Manager if I press F10 instead of F8 (while highlighting Windows 7) it takes me to an "Edit Boot Options" screen: Edit Windows boot options for: Windows 7 Path: \Windows\system32\winload.exe Partition: 2 Hard Disk: 8e90e329 [ /NOEXECUTE=OPTIN (I CAN EDIT THIS LINE) ] Update: I found my Windows 7 Media Disk and it did not help out. The laptop had the "System Restore" as a partition on the HDD. I later received (in the mail) a Windows 7 Upgrade Disc from Sony to upgrade my system from Windows Vista to Windows 7 Ultimate. I placed the disc into the DVD drive and it does not come up as a "bootable" disc. I'm going to try to find an alternative disc to see if I can get into Command Prompt. Update 2: I got a Windows Repair disc and got into a command prompt window. I got into the registry and disabled Deep Freeze. Also: I renamed the Pending.xml file to Pending.old I cleared out the Windows Temp directory I still am stuck in the loop (though, it isn't an issue with DeepFreeze anymore because I can make changes to the hard drive and they persist). Not sure what to do at this point? Update 3: I ran the repair option and it couldn't repair, but it did point me to something. It says the error was due to a driver that was failing. I have a feeling it is my UPEK Fingerprint scanner.

  • Bind the windows key to Lubuntu start menu

    - by abel
    I am running Lubuntu 11.10. By default the main menu is bound to Alt+F1 (A-F1) which works. Here is the relevant code from ~/.config/openbox/lubuntu-rc.xml <keybind key="A-F1"> <action name="Execute"> <command>lxpanelctl menu</command> </action> </keybind> This works. When I hit Alt+F1, I can see the start menu. If I change the keys to "Windows key + M" (W-m), I can pull up the start menu using Win+M <keybind key="W-m"> <action name="Execute"> <command>lxpanelctl menu</command> </action> </keybind> However, I cannot bind the start menu to the Windows key alone. If I try replacing "W-m" by "W", the "W" alphabet key gets bound to the start menu. If I try "W-" nothing happens, I have tried the "Super" option too but to no avail. How can I bind the Lubuntu main menu to the windows Key? I have been through some relevant lubuntu questions, like this one, which tries to do the opposite. How do I unbind Super key from menu in Lubuntu

  • How to open python scripts directly by typing in their name in terminal (Mac OS X)

    - by Haffi112
    I'm working on installing django and running it on my system. I have a problem though, in this tutorial creating a project is explained by running the command django-admin.py startproject mysite My issue is that this doesn't work. I changed to the directory where django-admin.py is located and ran the command chmod +x django-admin.py with no results. I tried adding the directory with the file to my path without results. I ended up fixing my problem with this command python /location/of/django-admin.py startproject mysite which yielded the outcome I expected. My problem is: What do I need to change/configure such that command django-admin.py startproject mysite would be sufficient? Here are some experiments: 21:09~/Desktop/HI/NSN/Polls > django-admin.py startproject mysite -bash: django-admin.py: command not found 21:09~/Desktop/HI/NSN/Polls > ./django-admin.py startproject mysite -bash: ./django-admin.py: No such file or directory 21:09~/Desktop/HI/NSN/Polls > python django-admin.py startproject mysite python: can't open file 'django-admin.py': [Errno 2] No such file or directory 21:09~/Desktop/HI/NSN/Polls > /opt/local/lib/python2.4/site-packages/django/bin/django-admin.py startproject prufa1 -bash: /opt/local/lib/python2.4/site-packages/django/bin/django-admin.py: /opt/local/bin: bad interpreter: Permission denied 21:09~/Desktop/HI/NSN/Polls > sudo /opt/local/lib/python2.4/site-packages/django/bin/django-admin.py startproject prufa1Password: sudo: unable to execute /opt/local/lib/python2.4/site-packages/django/bin/django-admin.py: Permission denied 21:09~/Desktop/HI/NSN/Polls > sudo /opt/local/lib/python2.4/site-packages/django/bin/django-admin.py startproject prufa1sudo: unable to execute /opt/local/lib/python2.4/site-packages/django/bin/django-admin.py: Permission denied 21:09~/Desktop/HI/NSN/Polls > python /opt/local/lib/python2.4/site-packages/django/bin/django-admin.py startproject prufa1 21:09~/Desktop/HI/NSN/Polls > ls mysite prufa1 Final edit: The problem is solved, see Ian C's answer for the right solution.

  • Want to Run OS Commands From WLST?

    - by Bala Kothandaraman
    If you spend a lot of time with WLST in the interactive mode, I am sure you have opened another command prompt/shell to check something at the OS file system level. If you wonder whether can execute an OS command from within WLST prompt, the answer is "Yes". This is very convenient similar to how you can execute OS commands from within "Vi" editor. In fact this feature is not from WLST but from underlying Jython. There is "os" module in Jython that provides a unified interface to a number of operating system functions. There is "system" function in the "os" module that can take a OS command as a string input and returns either "0" or "1" depends on whether the command was successful or failed. So this feature can also be used with scripting mode where the return code can be verified for further processing in the script. For eg. os.system(r'dir c:\bea') can list the contents of the bea folder under c drive. Notice the use of the preceding 'r' for escaping the entire string.

    Using perl 5.8.8 on linux, need the output of a perl 'system' command to be hidden. The command in my code is : system("wget", "$url", "-Omy_folder/$date-$target.html", "--user-agent=$useragent"); I've tried using " /dev/null 2&1" in different places in the system command, like this- system("wget", "$url", "-Omy_folder/$date-$target.html", "--user-agent=$useragent"," /dev/null 2&1"); Can anyone help me with where the redirection to /dev/null should be?

  • Why do Finder and du report different file size?

    - by flipdoubt
    I am writing a geektool 3 script to show the size of a particular VMware Fusion virtual machine. Get Info in Finder says the file is "52.91 GB". I run the following du command to get the file size: > du -hs ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hs command returns the file size as "49G". What accounts for the difference from what Finder reports? Alternatively, I have tried replacing the -s option with the -d option like so: du -hd ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hd command returns the file size as "59G". What accounts for the difference between Finder, du -hd, and du -hs? Also, this du -hd command produces no output in geektool 3. What gives?

  • How to solve package issues/dependencies

    - by Wolfgang Kuehne
    Background info I am trying to install Veins simulation environment by following the tutorial provided by the author. In step 1 it is required to install some packages in Linux, the tutorial suggest this commands to be executed on Terminal: sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openmpi-bin libopenmpi-dev libpcap-dev autoconf automake libtool libxerces-c2-dev proj libgdal1-dev libfox-1.6-dev When I execute this command, I immediately get: E: Package 'proj' has no installation candidate Then I remove the proj from the command and execute it again without proj in it, next I get: The following packages have unmet dependencies: libgdal1-dev : Depends: libgdal-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. So, I remove libgdal1-dev from the command as well. And it executes file, by downloading the remaining packages. To troubleshoot the problem with proj and libdgal1-dev I go to the Synaptic Package Manager. libgdal1-dev I search for libgdal1-dev in Synaptic Package Manager and I get an entry. I Mark for Installation and then Synaptic Package Manager suggests removing libxerces-c2-dev which is actually added via the initial command. Should I trust Synaptic Package Manager with this suggestion, and proceed further? proj What should I do about proj. There are some packages in Synaptic Package Manager such as proj-bin or libproj-dev. Should I install them? I think proj has to do with this and this What should I do to make sure that this simulation tool works fine?

  • SSH-forwarded X11 display from Linux to Mac lost after some time

    - by mklein9
    I have a new and vexing problem with ssh forwarding my X11 connection when logging in from a Mac (10.7.2) to Linux (Ubuntu 8.04). I have no trouble using ssh -X to log in to the remote machine and starting an X11-based application from that shell. What has recently started happening is that additional invocations of X11 applications from that same shell, after a while (on the order of hours), are unable to start because the forwarded display is being blocked (I presume). When attempting to start xterm, for example, I get the usual message about a bad DISPLAY setting, such as: xterm Xt error: Can't open display: localhost:10.0 But the X11 application I started right when I logged in is still running along just fine, using that exact same display (localhost:10.0), just that it was started earlier. I turned on verbose logging in sshd_config and I see this in the /var/log/auth.log file in response to the failed xterm startup attempt: sshd[22104]: channel 8: open failed: administratively prohibited: open failed If I ssh -X to the server again, starting a new shell and getting assigned a new display (localhost:11.0), the same process repeats: the X11 applications started early on run just fine for as long as I keep them open (days), but after a few hours I cannot start any new ones from that shell. Particulars: OpenSSH sshd server running on Ubuntu 8.04, display forwarded to a Mac running Lion (10.7.2) with the default Apple X server. The systems are connected on an Ethernet LAN with a single switch between them. Neither machine is running a firewall. Until recently (a few days ago) this setup worked perfectly so I am mystified as to where to look next. I am by no means an X11 or SSH expert but have good UNIX/Linux experience. Nothing obvious has changed in either client or server configuration although I have tried changing a few options to try to debug this, like setting sshd_config's TCPKeepAlive to no, and setting "host +localhost" (you can tell I've been Googling). When logging in from a Linux 11.10 laptop to the same remote host over the same network and switch, this problem does not occur -- an xterm can be invoked successfully hours later from the same ssh login shell while the same experiment from the Mac fails (tested this morning to be sure), so it would appear to be a Mac-specific issue. With "LogLevel DEBUG3" set on the remote machine (sshd server), and no change made in the client connections by me, /var/log/auth.log shows one slight change in connection status reports overnight, which is the port number used by the one successful ssh session from the Linux machine (I think), connection #7 below: sshd[20173]: debug3: channel 7: status: The following connections are open:\r\n #0 server-session (t4 r0 i0/0 o0/0 fd 14/13 cfd -1)\r\n #3 X11 connection from 127.0.0.1 port 57564 (t4 r1 i0/0 o0/0 fd 16/16 cfd -1)\r\n #4 X11 connection from 127.0.0.1 port 57565 (t4 r2 i0/0 o0/0 fd 17/17 cfd -1)\r\n #5 X11 connection from 127.0.0.1 port 57566 (t4 r3 i0/0 o0/0 fd 18/18 cfd -1)\r\n #6 X11 connection from 127.0.0.1 port 57567 (t4 r4 i0/0 o0/0 fd 19/19 cfd -1)\r\n #7 X11 connection from 127.0.0.1 port 59007 In this report, everything is the same between status reports except the port number used by connection #7 which I believe is the Linux client -- the only one still maintaining a display connection. It continues to increment over time, judging by a sequence of these reports overnight. Thanks for any help, -Mike

  • DENY select on sys.dm_db_index_physical_stats

    - by steveh99999
    Technorati Tags: security,DMV,permission,sys.dm_db_index_physical_stats I recently saw an interesting blog article by Paul Randal about the performance overhead of querying the sys.dm_db_index_physical_stats. So I was thinking, would it be possible to let non-sysadmin users query DMVs on a SQL server but stop them querying this I/O intensive DMV ? Yes it is, here’s how… 1. Create a new login for test purposes, with permissions to access AdventureWorks database only … CREATE LOGIN [test] WITH PASSWORD='xxxx', DEFAULT_DATABASE=[AdventureWorks] GO USE [AdventureWorks] GO CREATE USER [test] FOR LOGIN [test] WITH DEFAULT_SCHEMA=[dbo] GO 2.login as user test and issue command SELECT  * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks'),NULL,NULL,NULL,'DETAILED') gets error :-  Msg 297, Level 16, State 12, Line 1 The user does not have permission to perform this action. 3.As a sysadmin, issue command :- USE AdventureWorks GRANT VIEW DATABASE STATE TO [test] or GRANT VIEW SERVER STATE TO [test] if all databases can be queried via DMV. 4. Try again as user test to issue command SELECT * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks '),NULL,NULL,NULL,'DETAILED') -- now produces valid results from the DMV.. 5 now create the test user in master database, public role only USE master CREATE USER [test] FOR LOGIN [test] 6 issue command :- USE master DENY SELECT ON sys.dm_db_index_physical_stats TO [test] 7 Now go back to AdventureWorks using test login and try SELECT * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks’),NULL,NULL,NULL,’DETAILED') Now gets error... Msg 229, Level 14, State 5, Line 1 The SELECT permission was denied on the object 'dm_db_index_physical_stats', database 'mssqlsystemresource', schema 'sys'. but the user is still able to query all other non-IO-intensive DMVs. If the user attempts to view the index physical stats via a builtin management studio report  – see recent blog post by Pinal Dave they get an error also

  • MySQL – Beginning Temporary Tables in MySQL

    - by Pinal Dave
    MySQL supports Temporary tables to store the resultsets temporarily for a given connection. Temporary tables are created with the keyword TEMPORARY along with the CREATE TABLE statement. Let us create the temporary table named Temp CREATE TEMPORARY TABLE TEMP (id INT); Now you can find out the column names using DESC command DESC TEMP; The above returns the following result This table can be accessed only for the current connection and it can be used like a permanent table and automatically dropped when the connection is closed. However, you can not find temporary tables using INFORMATION_SCHEMA. TABLES system view. It will only list out the permanent tables. MySQL usually stores the data of temporary tables in memory and processed by Memory Storage engine. But if the data size is too large MySQL automatically converts this to the on – disk table and use MyISAM engine. You can also create a permanent table with the same name of a temporary table in the same connection. However the structure of permanent table is visible only if the temporary table with the same name is dropped. Let us create a permanent table with the same name Temp as below CREATE TABLE TEMP (id INT, names VARCHAR(100)); Now running the following command stills gives you the structure of the temporary table temp created earlier. DESC TEMP; You can drop the temporary table using DROP TEMPORARY TABLE command; DROP TEMPORARY TABLE TEMP; After you executed the temporary table, run the following command DESC TEMP; Now you will see the structure of the permanent table named temp In summary – If there is a Temporary Table in MySQL it gets first priority over the permanent table in the session.

  • Tip 16 : Open Multiple Documents within Single Application Instance Using C#

    - by StanleyGu
    1.       Using Microsoft Word 2007 as an example, you can open test1.docx and test2.docx at same time. The two documents are opened within single instance of the word application. World application supports command line argument of passing multiple documents. 2.       Again, Using Microsoft Word 2007 as an example, you can open test1.docx first and then test2.docx. The two documents are opened within single instance of the Word application. Word application supports Multiple Document Interface (MDI). 3.       Using Notepad as an example, you receive error message of “The filename, directory name, or volume label syntax is incorrect” if you want to open two documents at the same time. Notepad does not support command line argument of passing multiple documents 4.       Again, using Notepad as an example, you can open test1.txt first and then test2.txt. The two documents are opened to two different instances of Notepad application. Notepad does not support Multiple Document Interface (MDI). 5.       In conclusion, there is nothing you can do trying to rely on System.Diagnostics.Process class to open multiple documents within a single instance of an application because it is controlled by the application itself. The best approach is to read any developer or user guide of the application and make sure: 1. The application supports Multiple Document Interface (MDI) 2. The application provides command line argument of passing multiple documents. Then, you can use Process class and the command line argument syntax to open multiple documents for the application.
