Capture OCAP Codian

Hello world.

Can someone help me please. I would like to play a video call from Pcap file. I heard that we can seize wireshaek catches on Codian MCU

and play the video file to check the quality of the video for the loss of package lagg etc.

Please suggest.

Thank you

Just found out today through a case of TAC, you can do packet capture directly from the MCU, there are two warning however and are noted near the bottom.

 True for MCU 4.2 or newer, and Telepresence Server In order to start the capture, you will need access to the console port of the MCU/TS. MCU:> nettap usage: nettap [-a|-l|-s|-h] A|B -a : capture all packets (i.e. disable most of filter) -l : disable limit on number of packets captured (160000) stop with Ctrl-C -s : disable 128 byte limit on packet length -h  : only capture packets to from  § The A | B refers to port A or port B. In almost all cases you will want port A. For example, if you want to capture media coming from a particular endpoint at 192.168.0.5, you would use: MCU:> nettap -as -h 192.168.0.5 A Don't forget the -s, or you will only capture the first 128 bytes of each packet - no good for media (and not much good for protocol signalling either). The capture can be retrieved from the MCU/TS using the Web interface: Status > General > Download network trace. It's a good idea to delete it after downloading if CDR logging or Audit logging is enabled. Warnings Using on a busy MCU will cause problems Processing power is limited on Codian products, especially for 4200/8420, IP VCR and ISDN GW. Using nettap on a busy MCU is a lot of work (the MCU will be dealing with a LOT of traffic), and this could cause performance issues and potentially even stability problems. You will run out of space Space is also limited on Codian products, so capturing media for an extended period of time is not an option. Leaving a large trace on the box will also severely limit the space left for Audit and CDR logs.

  • PCAP Capture does not work

    Hello

    Yesterday I did a screenshot on my ASA 8.0 (3) 12. I can see the internal capture via https://ASA-IP/admin/capture/CapName and https://ASA-IP/capture/CapName.

    But if I try to download the PCAP file I get the download dialog box and a mistake 'OCAP ASA - IP could not be downloaded. I have the packages in my capture so that there should be a PCAP file.

    Any tips?

    Stephan

    Hello stephan,.

    In order to download the .pcap file, you can use the CLI and Web browser.

    From CLI just copy the *.pcap file to a TFTP server

    ASA /pcap #copy capture: cap_name tftp://tftp_ip_add

    LaissΘes just add "/ OCAP" end of commentary to the url "https://ip_add/capture/test/pcap".

    I hope it will work fine.

  • WebVPN - error: access method is not supported for the capture of WebVPN

    I'm watching a capture of webvpn on the SAA. I start the capture:

    test type webvpn user capture (entering a valid user name)

    Then I connect to the ASA to try to see track with "Using a browser to capture displayed data" as described in the setup guide.

    https:// / admin/capture/test/OCAP

    After login, I get this message in the browser:

    "Error: access method is not supported for WebVPN capture."

    If I stop the capture (capture test) before you try to connect, the error in the browser is:

    "404 not found".

    The/admin/capture/test/OCAP requested URL was not found on this server. "

    I have a mac pro running 10.6.8. Since I upgraded my iphone 5s today 10.0.2, I am unable to use Image Capture on my mac to transfer your photos, iphoto does not work either. I get a message on my phone to the computer I chose to 'trust', then I get an error message in the Image Capture in saying that I have to enter a password on my phone but the password is not displayed at the time.

    1. Connect your device to your computer, and then turn on the unit.

      If the device is locked with a password, enter it.

    2. In the Image Capture, select the device from the list of devices.
    3. Use the buttons at the bottom of the window to Capture of Image to display thumbnails in a list or as icons to change the size of thumbnails, or to rotate or remove images.
    4. In the pop-up menu to import to, choose where to save images or what application to use to open the image.
    5. To import only some of the photos, select the photos you want, and then click Import. To import all the photos, click Import all.

      Choose AutoImporter menu drop-down ' connection opens this [device] ' to transfer images from a device to your computer whenever you connect it to your computer.

    6. Select "Delete after import" to remove parts of the instrument after transfer to your computer. You can also select individual items on your device, and then press Delete on your keyboard.

  • Image capture will not work with Scanner

    Hello

    I have an Epson Perfection V550, which worked until I upgraded to Sierra. Now, although showing also installed and available as a device of Capture of Image, I get nothing more than Capture of Image that "waiting for scanner. It has been suggested that I reset via picture Capture TWAIN devices, but there is no other choice via the file menu.

    What can I do?

  • PDF Image Capture files

    Since the update to Sierra (although I can't say that this was the cause of the problem), I have a problem when parsing and saving documents in PDF format using the image transfer application. A PDF file is created but when I open the pages are naked with perhaps only sometimes visible top line (and which appears at the bottom of the page!). This problem occurs only when I choose the PDF format; If I choose to save as an image file (PNG, for example), it works fine.

    My printer driver is up to date and if I use software of third parties (e.g., HP Scan) this problem is specific to the application of Capture of Image so I can create PDF files successfully.

    This problem occurs on my iMac Mini and Mac Book Pro which have been updated for the last OS of Sierra

    You see the problem even if you scan to PDF using Preview?

    I use an excerpt instead of the Image Capture to do this and he continues to work very well in the Sierra AFAICT. I'll try with the Image Capture when I get the chance, just to compare. He used to work as well, but I've not scanned with it in quite awhile.

  • Image Capture App combining OS Sierra files

    Hi I have a problem with the application of Capture of Image integrated into the Apple OS since the update to the Sierra. Before the update I scan documents into the feeder of my MFP as a PDF file and select 'combine them into single document option. of course, I get a PDF file with the scans in. I would then analyze an other internal documents and again, I would get another PDF document with them in.

    Since the update OS Sierra and using the same settings as the first PDF file is created in the end, however when I go to scan the next set of documents Yes it creates another PDF file with these files in but she also adds the previous set of scanned files to the same doc. This continues for each subsequent set of scanned files. The only way I managed to prevent this must either exit the Capture Image soft after each set of scanned documents or in the test results window, select the magnifying glass next to the analysis the folder Apps of Capture Image temporary Doc and send these files to the trash. It's as if the app is no longer clearing Temp files between scans automatically.

    I see you have a problem with the scanning of documents in the application of Capture of Image.  I know it's important to have your applications work correctly, and I'm happy to help you.  To further isolate the issue, please create a new administrator account on the Mac.  A test to see if the problem of scanning is always present in the new user account.  Here are the instructions:

  • 7 iPhone very slow camera capture

    Hello world. You already have the iphone Go 7 256 1 week. I find the camera focus speed is acceotable but a bit slower than 6 sec. However, what I find most disturbing is that after I pressed the shutter release button it takesa very long time to capture the image of which lack the coup my kidd or blurry images. I compared it side by side with the iphone6 more. Then 5s snd 5. The results are disturbing. Even my 5 captured images faster 4 years together with a speed more slow focusimg

    Did a reset using itunes on pc NDS installation again and also using recovery as suggested by cat from apple. Always the same. searched on youtube on speed tests and note 2 reports that canera 7 is laggy. Anyone with questions? Is it hardware or software? Please notify. BTW also on the latest ios 10.0.1

    Sounds like a problem with the hardware for me since it has been restored. I suggest you to take over an Apple Store for testing. I have a 7 128 GB and my camera is not giving me any questions.

  • Image capture will delete everything?

    Capture images on Mac is a convenient and popular tool to delete photos on your iPhone.

    But when I start IC, what I see is a single mass of photos assigned to my phone. No albums or other ways to organize photos visible on the phone itself are visible here.

    So the question is, if bulk - delete you photos to the help of IC, who is also going to delete things from your phone as Favorites or other albums, you either created on the phone or that have been created by another application (for example Instagram)?

    EDIT:

    I confirmed that the removal of a photo by IC will remove other albums on the phone in addition to the camera. I tested with the Instagram album open on my phone when deleting an image in IC I know has been stored via Instagram. Of course, he immediately disappeared for the phone album. Bad luck.

    The bottom line is I'm emptying my camera, but I don't want things to disappear from the others, these albums more carefully organized on the phone.

    It can only access the photos and videos from the camera to roll. Items further albums cannot be manipulated by Capture images or Photos.

  • image capture does not recognize my iPhone when I connect to my mac?

    I have the iPhone, when I connect it to my photos of mac does not open... How can I put on it to open it

    Hello rosrich,

    If I understand your message that you are eager to the Mac to open Image Capture when you connect your iPhone so that you can import the photos. I would like to have the possibility of having an auto app launch when I connect my iPhone as well. I'll be happy to help you with this.

    If you go ahead and open Capture of Image and then connect the iPhone, in the lower left corner, you will see the name of your iPhone and the "connection this iPhone opens:" you have the option to choose what app that you like. So if you want Image Capture to open when you connect your iPhone, you would select which. If you want pictures to open, you would select Photos instead. Information on the AutoImporter lies in the following article:
