Can't capture packets with tcpdump or dumpcap/tshark. Sigsev (Linode)

I'm running arch linux on my linode, everything is up to date in pacman. Whenever I try to run tcpdump or tshark it just gives me "Segmentation Fault". I checked the packages repo site and saw someone having the same issue and the fix was creating the /dev/bus/usb/001/001 which didn't fix the issue for me (still segfaults). When setting up the char device it uses the major version 189 which is usb_device on my linode /proc/devices doesn't show a usb_device anywhere.
So is there something I need to install or something I'm missing? In the past tcpdump has worked with no issues.
Thanks for reading, hope you can help.

You might want to try running it with gdb and do a backtrace after it segfaults to see what's causing that.

  • Ace 4710 can I capture packets on a Load Balancer

    We have just implemented JD Edwards we have three servers front ended by ACE4710,most things are good, but I there are some reports(.CSV)generated by the system that cannot be viewed  when going through the load balancer, but ok if going directly to the server. I have logged on as a user that is getting the problem, and it is ok for me! So it looks as if it could be a PC problem, but other people think it must be the LB. is there anything like Tethereal available within the ACE that I could use to capture packets.

    Hi,
    There isn't a tethereal built-in to the ACE, but you can capture packets.
    You need to create an ACL to identify the interesting traffic and then use the capture command. This is documented in the command reference guide.
    When you stop the capture copy the file from flash to disk0: ('copy capture disk0:') The copying converts the capture into a pcap format file readable with any sniffer tool like wireshark. You'll need to download the file from disk0: to a workstation to be able to run wireshark against it.

  • Trouble Capturing Packets with Embedded Packet Capture

    Hi All,
    I am trying to capture packets originating from a server to a host device across three switches:
    server -- 6513 -- 3850 -- 3550 -- host A
    I am doing a ping from the server to host A. The packet capture is being done on the 3850. This is my configuration:
    access-list 100 permit icmp host 192.168.101.6 host 192.168.100.188
    access-list 100 permit icmp host 192.168.100.188 host 192.168.101.6
    end

    monitor capture buffer TRACE filter access-list 100
    monitor capture point ip cef CAP g1/1/1 both
    montior capture point associate CAP TRACE
    monitor capture point start CAP
    I then issue a ping from the server to host A. Interface g1/1/1 is where the 6513 connects to the 3850. When I issue a show monitor capture buffer all parameters, there are no packets. If I remove the filter from the buffer I still do not see the packets.
    Does anyone have any advice here?

    I tried recreating the packet capture with no access-list filtering.

  • Can't capture ntsc with color

    hi
    i want to capture ntsc videos. i'm playing back on a panasonic multisystem vhs nv-hs820 going into a acapus advc-110 and then into imovie.
    i've tried every imaginable set up in imovie, and everyout different output from the panasonic and switched every switch on the advc but i can't get the movies to import in color.
    i have a decent black and white picture but no color.
    any ideas on what i could be doing wrong or how to solve the issue?
    thx, sharkboy13

    Your analogue-to-digital converter can't get a grip on the colour signal, which sits on a frequency which it can't decode.
    It's the advc device, not iMovie, which is the problem (..although your TV may be able to display the colour info, other devices can't necessarily do so).
    If you can't get any kind of upgrade to the device (..probably not available..) then you may have to find another way to do it.
    There was a similar question about this a month or two ago, and it was just impossible to get the converter to cope with the colour info.
    Sorry!

  • Can't capture HDV with Canon Legria hv40

    Hi,
    I'm having this very irritating problem - when I try to capture HDV(25) footage with Premiere Pro CS6 the program:
    recognizes the camera
    has control over camera navigation
    doesn't show preview in the capture window
    says it's capturing, but only captures audio from the camera (in mp3)
    I'm using FireWire and all the Premiere/camera settings are set to HDV.
    I can't figure out what the problem might be here.
    Any help greatly appreciated!
    Thanks

    I originally had this problem with a  #trial version of CS5.5 and it did exactly what you describe, (incidentally Sony Vegas Movie Studio Platinum 11 @ $75 USD, captures perfectly) ,but, on going to full version and upgrade to CS5.5.2 it has been working perfectly for the last 18 months. (It won't help you but, HDV Canon Capture in Premiere Pro 1.5.1. and that is 5+years old was/is very efficient)
    And later as well, just double check New Sequence > Presets > HDV 1080i 25 (50) or other .
    Click on Preset Descriptions it will show what it is doing.
    Good luck
    #Ps. This occurred in a downloaded trial version (Adobe may not have included the HDV/mpeg-2 codec or it may have been corrupted), but, there is no problem here on 2 x i7 64 bit computers running the program from disc.

  • Can't capture video with FCP 5.1

    Hi All,
    Here is the case. I'm trying to capture the video from my newly baught Sony HDR FX7. Here are the specs:
    I've connected it thru Firewire 400 on the back of my G5.
    G5 660GB HD, 5.5Gb RAM
    In Easy set up I've selected HDV-1080i60
    When I go to file-log and capture, it connects to camcorder and says VTR OK on the bottom of the screen.
    When capturing the video (after I've connected to log and capture I push play on camcorder and then click capture now on FCP) I could see on the capture screen and my video running but here an there a green line would cross the film and then it would slow down for a 10th of a second and line would run accouss the capture window again. The type of lines you'd get in the old movie? .
    After I've captured all 5 sigments I had on the tape and when I tried to play (I went to file-import-file, I've selected the captured clip from my internal HD where the FCP put the files). The file opened in browser. And then it open in preview window of FCP. At this point the clip that is 1 minute long would play for 2-4 second and end there. The quality of it was also very, very poor (and I filed it at HD 1080i.
    So, the quality was really poor. It was the case with all 5 clips I've captured from FX7. All of them 2-4 sec. long and very poor quality.
    Now, if I try to play the clip from camcorder and select "in" and "out" points and then batch capture via the same log and capture window, it would tell me that it's "unable to locate timecode, the timecode appears to be missing from the tape. Please verify that tape is timecoded correctly"
    So, I was reading this forum and did this:
    Tried to go to user preferences and set "on time code brake" select "make new clip"
    Nothing helped.
    Also it's worth noting. When I push play on camcorder and click capture now, new window comes up and it says on the bottom of it "searching for meadia..." press esc to stop or something like that. May be it's not finding it?
    Also, when I first filmed with this camera, I would stop after every clip, turn off the camera, plug it into tv and preview what I've filmed.
    Either way, the few seconds of the clips that I"ve got are very bad quality. When I view the clips on my TV and monitore connected thru 3 colored cables, the video was ok, I'd even say good, just too much noice in it. But quality of capture is horrible.
    If anyone is readying this, could you please give me some ideas where to go with this. I don't know what to do from here

  • CP5: Can't capture remotely with a VM

    We've had a couple of experiences where we haven't been able to capture remotely if the client is using a Virtual Machine.  This is a real problem, since we are often working in an application in pre-release stages, and the client is using a VM to build it.
    Has anybody seen any solutions to this?

    No, unfortunately, it's not about capturing an application.  We always capture the screen area, actually.  We can get the screenshots, but not any clickboxes, etc.

  • Can't view all captured packets.

    Hello,
    Is there any command which allows to change number of displayed captured packets?
    I have a following capture setup:
    capture SFTP_TEST type raw-data access-list SFTP_TEST buffer 200000 interface inside circular-buffer [Capturing - 199102 bytes]
    when I issue command show capture SFTP_TEST I get:
    1676543 packets captured
    1...
    2...
    and so on
    157 packets shown.
    So far I have tried:
    show capture SFTP_TEST count 10000
    same result (only 157 are shown)
    same when I try
    show capture SFTP_TEST count 10
    (always displays magic number 157)
    I have a very similar capture setup on another firewall and I can view all packets without any problems.
    Any help will be much appreciated.
    Regards

    Hi Jouni,
    Thanks for replying.
    I though the same, but the confusing bit was different number of packets captured and number of packets displayed.
    Looks like the “packet captured” shows total number of packets processed by the defined capture rather than packets in the buffer so it makes sense what you said.
    I have reconfigured this with the maximum 33554432 buffer and I’ll post the outcome in few days.

  • Can I scan documents with Image Capture?

    I can no longer scan documents with my HP printer now that I have Maverick.  I can scan pics with Image Capture.  Is there any way to scan documents with image capture or with some other software? 

    Don't feel bad you are not alone.  I have a HP photosmart C4780.  Since upgrading to Mavericks it has been difficult to use the scan feature except via image scan.  I spent well over a month on the HP forums trying to discern whether or not new drivers were being developed and essentially got the run around.  Very crappy service from HP.  I'll not purchase one of their products again.  It appears that my all in one (which I brought through the Apple Store) is obsolete.  Anyone got any advice.  I'm contemplating seeing how many pieces it will shatter into upon being launched from my window.

  • Can not capture with CS6 and blackmagic multibridge pro on HP Z820

    This is the setup:
    Z820 and Windows 7 pro
    Multibridge Pro and driver 9.7.7
    CS6.0.5
    In premiere I can not capture via the Multibridge. The app crash when entering capture mode. I can not change setting in my capture device.
    On the same PC I CAN capture with Media Composer v7 and BM Media Express.
    I've tried several version of the BM driver, no changes.
    The BM PCIe card is in slot 1 and the PC bios I have update to v3.50.
    Anyone having the same experience?

    Thanks for the reply. I know YouTube is not the way to check quality but it shows the stutter in playback. The quality wasn't the issue and it is filmed with my phone. The video shows what it needs to show.
    Disk setup is a ddp server (check http://www.dynamicdrivepool.com/ for info) connected with 2 network cables for optimal speed.
    Video cars is a NVIDIA Quadro K4000.
    Premiere Pro CC is up to date with the latest version.
    Export settings? I think you mean sequence settings:
    For the record: I'm not trying to play a sequence with multiple layers of video of different codecs and loaded with effects. It's just a video chopped to pieces and an adjustment layer with some simple effects. The way Adobe is advertising the performance of Premiere Pro, one would think that couldn't be a problem for any Z820. Or that's what I was thinking. Hope you or anyone can help.

  • HELP! Can't capture with FCE4

    I went today to a Mac Store to try FCE4 armed with my Canon XHA1... and couldn't capture at all. It says on the product description that it supports HDV format (the one I used with my camera) but still didn't find a way around. Is there something I'm missing? Can I capture with FCE4? Is there something I need to do in terms of setup either with the software or the camera?
    Thanks in advance for your help!

    If there was a dialog message from the application it would be good to know exactly what that said and when that message appeared. The Apple Intermediate Codec is installed with QuickTime. If you do not have that the system was not properly installed. Perhaps you used a setting on the camera which is not compatible with FCE. What exact settings did you using on the camera? What exact settings are you using in FCE? Is the camera set to output what you shot. Many HDV cameras will downconvert so they output a DV version of your media. With minimum information there is no way anyone can help you. Please give complete information about your system and settings and drives and how everything's connected.

  • Can I capture a picture with my ipad, and save it as a PNG and/or SVG file to a specific folder?

    Can I capture a picture with my ipad, and save it as a PNG and/or SVG file to a specific folder?

    Kind of, sort of. (You can't save as SVG, but you can export as PNG.) PS Touch projects themselves are self-contained UNTIL they are exported, and even then they'll get exported to a specific location. (e.g., To the Camera Roll or Gallery/Photos, to Creatve Cloud, etc.)
    The procedure would be to start a new project using the "add image" icon (looks like a landscape with a plus sign, in the lower right in the project selection user interface) > Camera. Take your picture, then PS Touch will bring you to the editing user interface. Edit your image as appropriate.
    Go back out to the project selection user interface by tapping the back arrow in the upper left to save. You can then export the project using the export icon (5th icon from the upper right).

  • How can capture audio with labview

        I desired to make a audio equalizer vi using lab view. Audio will be taken from microphone. How can I capture sound from microphone with labview?

    See the example "Sound Card AutoPower Spectrum" This allows you to sample from an input device through your sound card, and take a spectrum.  you should be able to bin the spectrum by frequency bands, and show the histogram of frequencies.  You probably can even selectively resample and scale the frequencies, mix the signal and output the new sounds but I hav not tried this (I am not an audiophile so this is beyond my scope of expertise)  Good luck  ,
