Why netstat does not export cumulative values?

I would be grateful if someone could explain why the following does not export the cumulative values as implied by the manual page:

netstat - I have en0 w 5 b

Hello

Quote from the page for netstat (1).

If a timeout is specified, the protocol information on the last seconds of the interval will be displayed.

And I get something like this:

$ netstat -I en0 -w5 -b
            input          (en0)           output
   packets  errs      bytes    packets  errs      bytes colls
         3     0        210          1     0         90     0
        25     0       1927         38     0       2503     0
         5     0        379          7     0        451     0
         0     0          0          0     0          0     0

Tested under OS X 10.6.8.

  • DAQ Assistant does not export the values on the scale

    Hello all-

    Potentially stupid question but here goes: I'm using the DAQ Assistant to read in 4 analog input voltages, continuous sampling acquires data at 10 Hz 1 point, using LabView 12 on a machine with an acquisition of data USB-6341 simulated device (because my office is more comfortable than the lab!). I want to change the first two signals of voltage to temperature and humidity, respectively. I used the «create a new...» "in the 'Custom Scaling' drop-down in the"Voltage configuration"tab for each of these channels, named gave the slope and the intercept at the origin for the respective linear scales and click OK."

    When I test the code - and yet once again, I'm not on a machine with a 'real' DAQ system, I use a simulated device, and it seems that NEITHER MAX generates a sine wave of long period with little noise on top for this - I do not get the results on the scale of my 'signal', I get the raw tension. (If you run my code, I will join, the Relative humidity must be between 0 and 100 and temperature-40 to 60, is not 0 to 5, for example.)

    So, what happens? Is there some flag or setting that I missed? The scaling only works on voltage data 'real' of a 'real' instrument DAQ, instead of a simulation (which is why I mentioned twice!)? I have to do something in NI MAX as well as Labview?

    Thanks for any help you can give.

    Simulations devices will not respond to custom scale.  They are just supposed to allow you to configure your device without errors when you do not have the unit on-site.

    "NOR-DAQmx simulated devices create a noisy sine wave to all the entered analog." Simulated data other set-up is not available at this time. »

    http://www.NI.com/white-paper/3698/en

    They generate a sine with an amplitude equal to half of your specified input range.  If you want to work with simulated data that would be more realistic for your application, you could write a VI to generate the data and have a business structure to manage both "simulations" and "real", then you could switch back depending on whether you have access to the material.

    I just checked this with a PCI-6254 I install and simulated a PCI-6254.

  • APEX_ITEMS does not store the value in the SESSION after the validation error

    Hello

    I'm build dynamically using APEX_ITEMS, but it does not keep the value when the page is submitted and the validation error occurs. Here are the following steps that I am following.

    When I enter SUE (more than 8 characters), SUBMIT, validation fails and the error is displayed on the page (which is fine)
    BUT it does not keep SUE value (which I got) and filled with the old value which is ABC.

    WHY it does not keep the value that the user entered (even as the normal Page items)

    Region PL\SQL
    declare
      v_value varchar2(20);
    begin
      v_value := 'ABC'; 
      htp.p(apex_item.text(7,v_value));
    end;
    Validation (function returning the error text)
    DECLARE
     v_count number;
     v_value varchar2(50);
     v_value1 number;
    BEGIN
      v_value := apex_application.g_f07(1);
      select length(v_value) into v_value1 from dual;
    
          if v_value1 > 8 then
              return 'Field must have less than 9 character';
          ELSE
             return null;
          END IF;
    END;

    You use collections if you want the State to show if, after a validation error. Unfortunately, this is the case if you do not use the normal tabular forms.

  • Why Muse does not change the names of certain images or property when exporting to HTML format?

    Why Muse does not change the names of certain images or property when exporting to HTML format? and how can I keep the integrity of the name that the image/file has been saved as?

    General Muse renames a file imported image if the image is modified to achieve the design or the exit, or if the name change was necessary due to a name conflict (two different images which had the same file name when importing).

    The design-time features that will modify an image include cropping, rotation, rounded corners and effects (drop shadow, bevel or glow). It is also true that, in rare cases, Muse will merge an image with other content to optimize page download performance. An example of this would be to place a background image on a block of text that contains the text using system fonts. In this case, rather than a single image for text output and a separate image for the background, Muse will combine the two into a single image.

    If an image is placed or imported by Muse and not tampered with, the image is crossed without modification (including the file name) at export/publish (with him except that Muse will always rename if two different images with the same name).

  • Change event - why is does not select the current value, just the previous value?

    Hello.

    I use the script when the user selects a value from the drop box, something visible text (using the ' presence')

    I use the change of the event, but it does not work very well. When I select a value, it does not change the text, but if I select another value, it will display the previous selected value.

    Why did he not synchronize the value?

    Thank you!!

    Hi Rafael,.

    I don't know if you are using an event well.

    mouseExit is something good to use (especially when paired with the mouseEnter), during the change of the visual appearance of an object. For example, a button where the legend is underlined on mouseEnter and not highlighted on mouseExit.

    If you want to change the presence of objects on the form that the flat user above the list drop-down, then mouseEnter/mouseExit should work. However, if you want the changes occur once the user selects an item in the drop-down list, I recommend the exit event.

    Here are some examples:

  • Windows Vista mail program does not export the files all contacts

    After I exported my contacts from e-mail in vcf format windows in a new folder on my desktop, I noticed that NOT all contracts are present in the new folder.   If the contents of the folder, I show the long side windows messaging contacts which I exported the contacts I see some (to be precise, 256) are missing in the new folder. I exported 3 times, each time in a new folder and get the same results. I see that some of the missing files are group folders (apparently Windows Mail does not export to group files in vcf format) but the other files are simply not in the contents of the desktop folder.

    How can I get all the files AND folders in groups to export correctly?

    I was going to say that if you were interested in the migration of these contacts to another Vista computer, you can simply copy the file C:\Users\username\Contacts to your USB and then copy it to the other computer. Which retains all the attributes, including groups.
     
    For any other use, you're stuck fairly well with help of VCF or CSV format to export/import. Sorry, I have no idea why so many contacts are missing when you did.
     
    There is another method (roundabout). Install the free Windows Live Mail program, which will automatically import all contacts from Windows Mail. Be sure to select the option Live ID when prompted by the installer of Windows Live Mail. Therefore, you can keep all your contacts in perfect sync with other computers running Windows Live Mail, and you also have access to the contacts on any computer connected to the Internet by simply go tohttp://contacts.live.com and sign in with the same Live ID.

I understand that windows Mail export NO groups, but there are only 9 groups from my list of contacts. WHY other contacts don't get exported? I'm doing something wrong and if so, what?

    Why Overwatch does not not on all Apple computers?

    Because it runs on Windows and the authors have not written a version of OSX. You could set up "Boot Camp" and install Windows on that, then you can run it if your machine is capable (although it will not work on a Windows computer up-to-date). You can also install Windows in a 'virtualizer' such as Parallels, but it is quite unlikely that a complex game would run satisfactorily.

    Why iMovie09 does not recognize photos in projects?

    I made a new projects and adds several still images. Photos are displayed in the project field, but right the screen remains black.

    I checked one of my old projects with still frames that will work perfectly, but it has the same problem - the photos do not appear on the screen more.

    Is there something that can be done? I also noticed that I can't get iPhoto to iMovie to add photos, not more, and Photo Booth is available.

    An iMovie11 upgrade would solve the problem? I do not have doen that, due to the large amount of results negative comments on iMovie 11 receipt.

    This is a bug widely reported with iMovie versions 8 or 9 ('09 or 11) under El Capitan.  Only iMovie 10.1.1 works 100% on El Capitan.

  • Why Apple does not allow an iPhone to do scan WiFi?

    About 4 years ago, Apple pulled all applications that have enabled an iPhone search for WiFi networks. Why? (There was something for developers who use "Private APIs").

    There are a number of tools available for analysis for Macs. I helped a café owner to untangle its WiFi (it had both an old, disconnected and a new active WiFi router, and had the same channels as the business side) and used my scanner for Mac to try to optimize my home network. But I still have a low coverage in some corners of the House. An iPhone would be a perfect device to determine interference and blind spots, because it is much more portable than my laptop. But Apple does not allow this use.

    Why Apple does not allow this very convenient using an iPhone? I just read about a hack that allows it to display the power of a cellular signal in detail. But you can't do it for WiFi. It makes no sense to me. Apple could do this job if she wanted to.

    Thanks for any thoughts.
