  • grep pattern interpretted differently in 2 different systems with same grep version

    - by Lance Woodson
    We manufacture a linux appliance for data centers, and all are running fedora installed from the same kickstart process. There are different hardware versions, some with IDE hard drives and some SCSI, so the filesystems may be at /dev/sdaN or /dev/hdaN. We have a web interface into these appliances that show disk usage, which is generated using "df | grep /dev/*da". This generally works for both hardware versions, giving an output like follows: /dev/sda2 5952284 3507816 2137228 63% / /dev/sda5 67670876 9128796 55049152 15% /data /dev/sda1 101086 11976 83891 13% /boot However, for one machine, we get the following result from that command: Binary file /dev/sda matches It seems that its grepping files matching /dev/*da for an unknown pattern for some reason, only on this box that is seemingly identical in grep version, packages, kernel, and hardware. I switched the grep pattern to be "/dev/.da" and everything works as expected on this troublesome box, but I hate not knowing why this is happening. Anyone have any ideas? Or perhaps some other tests to try?

  • Git pull auto complete OSX

    - by vodkhang
    Follow some instruction on this site http://denis.tumblr.com/post/71390665/adding-bash-completion-for-git-on-mac-os-x-leopard . I can do git auto complete for MAC OS. However, when I type git pull origin ma (for master), and then tab it takes a long time for git to auto complete to become git pull origin master . I think it connect to the server to get the branch, but I am not sure, is there any way to make it faster and only get the branch on local machine cd /tmp git clone git://git.kernel.org/pub/scm/git/git.git cd git git checkout v`git --version | awk '{print $3}'` cp contrib/completion/git-completion.bash ~/.git-completion.bash cd ~ rm -rf /tmp/git echo -e "source ~/.git-completion.bash" >> .profile

    - by mark smith
    Hi there, Does anyone know of a good link to explain how to use the web.config...... For example, i am using forms authentication... and i notice there is a system.web and then it closed /system.web and then below configuration there are additional location tags here is an example, if you ntoice there is an authentication mode=forms with authorization i presume this is the ROOT....... It is also self contained within a system.web .... Below this there are more location= with system.web tags.... I have never really understand what i am actually doing.. I have tried checkign the MSDN documentation but still i don't fully understand up.... Can anyone help? If you notice with my example.... everything is stored in 1 web.config... i thought the standard waas create a standard web.config and then create another web.config in the directory where i wish to protect it..??? <configuration> <system.web> <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" /> <authentication mode="Forms"> <forms loginUrl="Login.aspx" defaultUrl="Login.aspx" cookieless="UseCookies" timeout="60"/> </authentication> <authorization> <allow users="*"/> </authorization> </system.web> <location path="Forms"> <system.web> <authorization> <deny users="?"/> <allow users="*"/> </authorization> </system.web> </location> <location path="Forms/Seguridad"> <system.web> <authorization> <allow roles="Administrador"/> <deny users="?"/> </authorization> </system.web> </location>

  • WPF ComboBox SelectedValue not updating from binding source.

    Here's my binding source object: Public Class MyListObject Private _mylist As New ObservableCollection(Of String) Private _selectedName As String Public Sub New(ByVal nameList As List(Of String), ByVal defaultName As String) For Each name In nameList _mylist.Add(name) Next _selectedName = defaultName End Sub Public ReadOnly Property MyList() As ObservableCollection(Of String) Get Return _mylist End Get End Property Public ReadOnly Property SelectedName() As String Get Return _selectedName End Get End Property End Class Here is my XAML: <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" xmlns:local="clr-namespace:WpfApplication1" > <Window.Resources> <ObjectDataProvider x:Key="MyListObject" ObjectInstance="" /> </Window.Resources> <Grid> <ComboBox Height="23" Margin="24,91,53,0" Name="ComboBox1" VerticalAlignment="Top" SelectedValue="{Binding Path=SelectedName, Source={StaticResource MyListObject}, Mode=OneWay}" ItemsSource="{Binding Path=MyList, Source={StaticResource MyListObject}, Mode=OneWay}" /> <Button Height="23" HorizontalAlignment="Left" Margin="47,0,0,87" Name="btn_List1" VerticalAlignment="Bottom" Width="75">List 1</Button> <Button Height="23" Margin="0,0,75,87" Name="btn_List2" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="75">List 2</Button> </Grid> </Window> Here's the code-behind: Class Window1 Private obj1 As MyListObject Private obj2 As MyListObject Private odp As ObjectDataProvider Public Sub New() InitializeComponent() Dim namelist1 As New List(Of String) namelist1.Add("Joe") namelist1.Add("Steve") obj1 = New MyListObject(namelist1, "Steve") .

The ComboBox contains the names "Joe" and "Steve" and "Steve" is selected by default. However, when I click a button to switch the ObjectInstance to obj2, the ComboBox ItemsSource gets populated correctly in the dropdown, but the SelectedValue is set to Nothing instead of being equal to obj2.SelectedName. Thanks in advance!

  • Best way to keep a MS DOS application alive? (Virtual MS DOS)

    - by user11010
    Hi, I have a good old DOS application which is still required to run. Unfortunately the PC is dying and needs to be replaced. The PC was running Windows 98 and the software was executed in a MS Dos Command line. When we would order a new PC you would at least get a Windows XP which has the Win 2000 (NT) Kernel and is not DOS based. Now I need a strategy to be able to run a that DOS application on a new age PC. What I was thinking is to buy a standard office box and have a virtual PC or VMware setup which is running MS DOS and my DOS application? Would this be a way to go? Any concerns? What about 16Bit/32Bit… So any opinion, experiances or tip would be great …. Thanks

  • View controller is drawing under my navigation bar after popping ttthumbsviewcontroller

    - by scootklein
    I'm implementing the TTThumbsViewController from the Three20 project and things are finally starting to take shape. I push the TTThumbsViewController from the current view controller by just pushing it onto the current stack and animate the transition (common navigation controller push). My problem is that when I pop the TThumbsViewController view controller, the navigation controller is stuck in a mode where its view controllers are drawn UNDER the navigation bar (which is now translucent).

    So I have a linux box with two wireless interfaces, one is a station and the other an AP. wlan0 (station) - Connected to the internet connection wlan1 (AP) - Other clients connect to it.

  • How to comment out a block of Python code in VIM

    - by Rishabh Manocha
    I was wondering if there was any key mapping in VIM to allow me to indent certain lines of code (whether those lines have been selected in visual mode, or n lines above/below current cursor position). So basically something that converts the following def my_fun(x, y): return x + y to #def my_fun(x, y): # return x + y I am ok with using either # or """ for commenting out the relevant lines. Ideally, I would also like the same keymapping to uncomment the lines if the given lines have been commented out. Thanks

  • Windows 7 PC crashes after being locked a few minutes

    - by White Island
    I have a problem with an Optiplex 755 PC running (32-bit) Windows 7 Professional. I just installed the operating system last week, and ever since, it seems to crash when I lock the screen. It doesn't happen immediately; it's usually after I walk away, so a few minutes (but I'm not sure exactly how many). I have this non-specific error in the Event log. I've run a chkdsk, thinking it might be hard drive-related, but that didn't help. Any ideas on what to check and how are appreciated. :) Log Name: System Source: Microsoft-Windows-Kernel-Power Date: 11/17/2010 3:09:28 PM Event ID: 41 Task Category: (63) Level: Critical Keywords: (2) User: SYSTEM Computer: WORKSTATION.domain.local Description: The system has rebooted without cleanly shutting down first.

  • How to reference other locations in making multi-boot live cd

    - by Nrew
    There is a tool in pen drive linux that allows you to boot directly with multiple iso files. And here is a sample in the menu.lst which allows you to choose which iso file you want to boot. title Fedora 13 find --set-root /Fedora-12-i686-L.iso map /ubuntu-10.04-desktop-i386.iso (0xff) map --hook root (0xff) kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper persistent iso-scan/filename=/ubuntu-10.04-desktop-i386.iso splash initrd /casper/initrd.lz I'm just using it on my 8gb flash drive and the location of the iso file is in the flash drive itself. Is it possible to reference other locations. So that I could boot from it, without limitations. because the flash drive can only contain 8gb of data. Is it possible? Anyone here tried this before?

  • Ulimit settings in Oracle 11g on Linux 5

    - by Stuart
    Is there an issue with "Ulimit -Hn" being set too low (at 1024) when (Oracle recommend 65536)? This is for Oracle 64-bit 11g on Linux 5. It is one of the settings that appears to be woefully short of its recommendation. But I am also aware that the database server in question is an Oracle Data Guard Local Standby and should only really have a connection or two from its Primary database server (to ship the redo logs across). The Local Standby database server has 'hung' about 3 times in as many months and then requires a reboot. I do not have access to this server, so rely on others to look at logs etc. The sanity check on kernel params uncovered the low value for "ulimit -Hn". Has anyone ever seen that 'low' value cause a hang or crash?

  • How to create custom asp.net validator that works with UpdatePanel?

    I think that subject summs it pretty well... I have created my custom validators that work great when I put them on page in design mode. However if I place them in a usercontrol, and then try to add this user control to the parent page via updatepanel, then my custom validators just won't trigger. They simply don't work. Does anyone have any clue on what I have to do here? .net 3.5

  • Silverlight Dataform validation doesn't work

    - by VexXtreme
    Hi I can't get dataform and it's controls to catch exceptions when validating. Fir instance, I have: <PasswordBox Password="{Binding Password,Mode=TwoWay,NotifyOnValidationError=true,ValidatesOnExceptions=true}" /> All required properties are set to true. In the setter of my Password property I throw a ValidationException upon failed validation, but the data form doesn't catch it, it just causes the application to crash as if it were a normal exception. Am I doing something wrong? Thanks

  • How to change from own Internal/Extrernal DNS to use an outsourced service like DNS Made Easy?

    - by Joakim
    Our current setup is a co-located linux box with an openvz kernel with a handful virtual containers for www, mail etc. and one container run Bind9 with a split views configuration serving External and Internal DNS. The HW-Node runs a shorewall firewall and all containers uses private ip's. The box (and DNS) basically handles web and mail for a handful domains and it works well but we still think it would be a good idea to outsource the public DNS and now to my question... Although I am fairly comfortable with the server stuff and DNS, I'm far from a pro and guess I basically need some confirmation that I am thinking in the right direction in that I basically just move the content of our external view (with zone files) to the external service and keep the internal view (or actually remove the view), update the new external DNS with thier names servers, update the info at my registrar and wait for propagation or have I missed something? Maybe someone else here run something similar already and can share some exteriences? I found this question which at least confirms it can be done.
