  • how do I match movement of an object from 2d video into a 3d package ?

    - by George Profenza
    I'm trying to add objects in a 3d package(Blender) using recorded footage. I've played with Icarus and it's great to capture the camera movement. Also the Blender 2.41 importer script works in Blender 2.49 as well. The problem is I can't seem to get 3d coordinates for objects. I have tried Autodesk(RealVIZ) MatchMover 2011 and gone through the tutorials. Tutorial 3 shows how to link a vertex from a 3d mesh to a 2d trackpoint, but the setup is for camera movement. Tutorial 4 goes into Motion capture, but it uses 2 videos of the same motion taken with 2 cameras from different viewpoints. I've tried to bypass that using the same footage twice, but that failed, as the 3d coordinate system ends up messed up. What software do you recommend for this (mapping 3d coordinates to 2d tracked points and importing them into a 3d package) ? What is the recommended technique ? Any good examples out there ? Thanks, George

  • What response should be made to a continued web-app crack attempt?

    - by Tchalvak
    I've issues with a continuous, concerted cracking attempt on a website (coded in php). The main problem is sql-injection attempts, running on a Debian server. A secondary effect of the problem is being spidered or repeatedly spammed with urls that, though a security hole has been closed, are still obviously related attempts to crack the site, and continue to add load to the site, and thus should be blocked. So what measures can I take to: A: Block known intruders/known attack machines (notably making themselves anonymous via botnet or relaying servers) to prevent their repeated, continuous, timed access from affecting the load of the site, and B: report & respond to the attack (I'm aware that the reporting to law enforcement is almost certainly futile, as may be reporting to the ip/machine where the attacks are originating, but other responses to take would be welcome).

  • Detecting man-in-the-middle attacks?

    - by Ilari Kajaste
    There seem to be many possible ways to create man-in-the-middle attacks on public access points, by stealing the access point's local IP address with ARP spoofing. The possible attacks range from forging password request fields, to changing HTTPS connections to HTTP, and even the recently discovered possibilit of injecting malicious headers in the beginning of secure TLS connections. However, it seems to be claimed that these attacks are not very common. It would be interesting to see for myself. What ways are there to detect if such an attack is being attempted by someone on the network? I guess getting served a plain HTTP login page would be an obvious clue, and of course you could run Wireshark and keep reading all the interesting ARP traffic... But an automated solution would be a tiny bit more handy. Something that analyzes stuff on the background and alerts if an attack is detected on the network. It would be interesting to see for myself if these attack are actually going on somewhere.

  • GNU/Linux: SAS-disk detected as /dev/sg7 - not as /dev/sdb

    - by Ole Tange
    I have just installed a SAS disk into a Debian server. It was detected correctly and everything was fine. Then I moved the SAS disk to a different Debian server, the same hardware model and running same version of Debian, but here the SAS disk is detected as /dev/sg7 and not /dev/sdb. smartctl -a /dev/sg7 works fine, but fdisk and cat hang. I tried putting the SAS disk in another slot: Same problem. How can I force the SAS disk to be detected as /dev/sdb? # uname -a Linux maxwell 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux

  • Single file changed: intrusion or corruption?

    - by Michaël Witrant
    rkhunter reported a single file change on a virtual server (netstat binary). It didn't report any other warning. The change was not the result of a package upgrade (I reinstalled it and the checksum is back as it was before). I'm wondering whether this is a file corruption or an intrusion. I guess an intrusion would have changed many other files watched by rkhunter (or none if the intruder had access to rkhunter's database). I disassembled both binaries with objdump -d and stored the diff here: https://gist.github.com/3972886 The full dump diff generated with objdump -s is here : https://gist.github.com/3972937 I guess a file corruption would have changed either large blocks or single bits, not small blocks like this. Do these changes look suspicious? How could I investigate more? The system is running Debian Squeeze.

  • Image Classification - Detecting an image is cartoon-like

    - by kingb
    I have a large amount of jpeg thumbnail images ranging in size from 120x90 to 320x240 and I would like to classify them as either Real Life-like or Cartoon-like. Are there any applications that will have cartoon classification capabilities? This application should work on Linux, and should take an image path on the command-line and return either 0 or 1 (echo $?).

  • Mouse receiver stopped working after pairing mouse to an unifying receiver

    - by mp19uy
    I bought this mouse, logitech m510, which came with a nano receiver (no-unifying). Yes I know, the mouse is supposed to come with a unifying receiver but I bought it knowing that it won't come on it's original package and it will come with a no-unifying receiver. When I received it, everything worked ok but, after connecting the mouse to another computer using an unifying receiver (that also worked ok, btw), then, when I tried to connect back the mouse to my computer using the no-unifying receiver, I couldn't connect it. I tried everything from removing the batteries and reinstalling the drivers to restarting the computer and trying in different computers, but I couldn't connect them. What I think it happened, is that in fact if you check the documentation of the logitech m510 it says that it works with unifying receivers only, and even more, there is the following article explaining it: http://logitech-en-amr.custhelp.com/app/answers/detail/a_id/18001/~/using-my-m510-with-a-different-usb-receiver So my theory is that the problem was connecting it to a unifying receiver, and now, isn't recognize by another receiver. The receiver (the no-unifying one) itself is recognized by windows, and if I connect the mouse using a unifying receiver, it works. I would like to know if there is any know solution for this or if I can try something else to see if I can solve this.

  • How to detect/list rogue computers connected to a WIFI network without access to the Wifi Router interface?

    - by JJarava
    This is what I believe to be an interesting challenge :) A relative (that leaves a bit too far to go there in person) is complaining that their WIFI/Internet network performance has gone down abysmally lately. She'd like to know if some of the neighbors are using her wifi network to access the internet but she's not too technically savvy. I know that the best way to prevent issues would be to change the Router password, but it's a bit of a PITA having to re-configure all wifi devices... and if the uninvited guest broke the password once, they can do it again... Her wifi router/internet connection is provided by the telco, and remotely managed so she can log-on to their telco account's page and remotely change the router's Wifi password, but doesn't have access to the router status page/config/etc unless she opts out of the telco's remote support and mainteinance service... So, how could she check if there are guests in the wifi with this restrictions and in the most "point and click way"? In this case I'd probably use nmap to look for other devices in the network, but I'm not sure if that's the easiest way to do it. I'm not a wifi expert, so I don't know if there are any wifi-scanning utils that can tell us who's talking to the router... Lastly, she's a Windows user as I guess that'll influence the choice of tools available Any suggestions more than welcome Regards!

  • Audio recording, a tool for human-aided drum quantizing.

    - by basilio.mp
    I have this situation: the drummer records the track (8 tracks in a multitrack session). Now, how do I check how distant are the recorded beats from their theoretical position i.e.: there is always some error in human recorded tracks, but is there any software that can show me the ideal (theoretical, quantized) beat and the recorded one and could alert me if the error is too big. P.S.: I'm searching for a standalone tool, or for a plugin that can work with Adobe Audition 3 or Nuendo 3.

  • Are random packets normal?

    - by TheLQ
    About a month ago on one of my servers I started receiving random packets from IPs all over the world. So I did the smart thing and stopped putting off installing an IDS. This IDS is a ClearOS Gateway which comes with Snort and SnortSam. I enabled it, checked There is a total of 4 ports open, two of which forward to the server I'm talking about. These ports are 3724 and 8085, so they aren't going to be easily detected in a port scan. However checking some logs of this server I found that the attack is resuming. I found this ... Accepting connection from '75.166.155.122' [Auth] got unknown packet from '75.166.155.122' Accepting connection from '98.164.154.93' [Auth] got unknown packet from '98.164.154.93' Ping MySQL to keep connection alive Accepting connection from '70.241.195.129' [Auth] got unknown packet from '70.241.195.129' Accepting connection from '67.182.229.169' [Auth] got unknown packet from '67.182.229.169' Accepting connection from '69.137.140.38' [Auth] got unknown packet from '69.137.140.38' Accepting connection from '76.31.72.55' [Auth] got unknown packet from '76.31.72.55' Accepting connection from '97.88.139.39' [Auth] got unknown packet from '97.88.139.39' Accepting connection from '173.35.62.112' [Auth] got unknown packet from '173.35.62.112' Accepting connection from '187.15.10.73' [Auth] got unknown packet from '187.15.10.73' Accepting connection from '66.66.94.124' [Auth] got unknown packet from '66.66.94.124' Accepting connection from '75.159.219.124' [Auth] got unknown packet from '75.159.219.124' Accepting connection from '99.102.100.82' [Auth] got unknown packet from '99.102.100.82' Accepting connection from '24.128.240.45' [Auth] got unknown packet from '24.128.240.45' Accepting connection from '99.231.7.39' [Auth] got unknown packet from '99.231.7.39' Accepting connection from '206.255.79.56' [Auth] got unknown packet from '206.255.79.56' Accepting connection from '68.97.106.235' [Auth] got unknown packet from '68.97.106.235' Accepting connection from '69.134.67.251' [Auth] got unknown packet from '69.134.67.251' Accepting connection from '63.228.138.186' [Auth] got unknown packet from '63.228.138.186' Accepting connection from '184.39.146.193' [Auth] got unknown packet from '184.39.146.193' Accepting connection from '69.171.161.102' [Auth] got unknown packet from '69.171.161.102' Accepting connection from '76.0.47.228' [Auth] got unknown packet from '76.0.47.228' Ping MySQL to keep connection alive Accepting connection from '126.112.201.14' [Auth] got unknown packet from '126.112.201.14' Ping MySQL to keep connection alive Now that scares me. Why isn't Snort detecting this? How were they able to find this specific port? More importantly, what normally would these packets contain? Is this something I should be worried about? How can I stop this?

  • Bypassing "Found New Hardware Wizard" / Setting Windows to Install Drivers Automatically

    - by Synetech inc.
    Hi, My motherboard finally died after the better part of a decade, so I bought a used system. I put my old hard-drive and sound-card in the new system, and connected my old keyboard and mouse (the rest of the components—CPU, RAM, mobo, video card—are from the new system). I knew beforehand that it would be a challenge to get Windows to boot and install drivers for the new hardware (particularly since the foundational components are new), but I am completely unable to even attempt to get through the work of installing drivers for things like the video card because the keyboard and mouse won't work (they do work, in the BIOS screen, in DOS mode, in Windows 7, in XP's boot menu, etc., just not in Windows XP itself). Whenever I try to boot XP (in normal or safe mode), I get a bunch of balloons popping up for all the new hardware detected, and a New Hardware Found Wizard for Processor (obviously it has to install drivers for the lowest-level components on up). Unfortunately I cannot click Next since the keyboard and mouse won't work yet because the motherboard drivers (for the PS/2 or USB ports) are not yet installed. I even tried a serial mouse, but to no avail—again, it does work in DOS, 7, etc., but not XP because it doesn't have the serial port driver installed. I tried mounting the SOFTWARE and SYSTEM hives under Windows 7 in order to manually set the "unsigned drivers warning" to ignore (using both of the driver-signing policy settings that I found references to). That didn't work; I still get the wizard. They are not even fancy, proprietary, third-party, or unsigned drivers. They are drivers that come with Windows—as the drivers for CPU, RAM, IDE controller, etc. tend to be. And the keyboard and mouse drivers are the generic ones at that (but like I said, those are irrelevant since the drivers for the ports that they are connected to are not yet installed). Obviously at some point in time over the past several years, a setting got changed to make Windows always prompt me when it detects new hardware. (It was also configured to show the Shutdown Event Tracker on abnormal shutdowns, so I had to turn that off so that I could even see the desktop.) Oh, and I tried deleting all of the PNF files so that they get regenerated, but that too did not help. Does anyone know how I can reset Windows to at least try to automatically install drivers for new hardware before prompting me if it fails? Conversely, does anyone know how exactly one turns off automatic driver installation (and prompt with the wizard)? Thanks a lot.

  • Recommend alternative to tripwire?

    - by CarpeNoctem
    Looking for a host-based IDS comparable to tripwire. Preferably one that allows centralized management. Right now I use tripwire and though it works management and reporting through a central server would be ideal. I'm looking for recommendations that have actually been used and not just google results. Thanks!

  • Detecting login credentials abuse

    Greetings. I am the webmaster for a small, growing industrial association. Soon, I will have to implement a restricted, members-only section for the website. The problem is that our organization membership both includes big companies as well as amateur “clubs” (it's a relatively new industry…). It is clear that those clubs will share the login ID they will use to log onto our website. The problem is to detect whether one of their members will share the login credentials with people who would not normally supposed to be accessing the website (there is no objection for such a club to have all it’s members get on the website). I have thought about logging along with each sign-on the IP address as well as the OS and the browser used; if the OS/Browser stays constant and there are no more than, say, 10 different IP addresses, the account is clearly used by very few different computers. But if there are 50 OS/Browser combination and 150 different IPs, the credentials have obviously been disseminated far, and there would be then cause for action, such as modifying the password. Of course, it is extremely annoying when your password is being unilaterally changed. So, for this problem, I thought about allowing the “clubs” to manage their own list of sub-accounts, and therefore if abuse is suspected, the user responsible would be easily pinned-down, and this “sub-member” alone would face the annoyance of a password change. Question: What potential problems would anyone see with such an approach?

  • Windows Media Player 11 Not Detecting Autoplaylists

    - by tuna
    Every time I open Windows Media Player it fails to detect my autoplaylists stored in <my music library dir>\Playlists. This appears to lead to sync problems since I (exclusively) use autoplaylists to sync music to my mobile. As WMP 11 fails to find the any sync autoplaylists it infuriatingly seems to decide that I want no music at all on my phone and proceeds to delete all my music off my phone. I guess these are two seperate problems but it seems to me they are related. If anyone can shed any light on a fix, that would be much appreciated. Many thanks

  • iTunes can't see iPhone after reinstalling Leopard

  • Single hardware unit to protect web servers and implement smart publishing

    - by Maxim V. Pavlov
    Thus far we've been using the combination of Forefront TMG 2010 as an edge firewall + intrusion prevention system + web site publishing mechanism in the data center to work with a few web server machines. Since we develop on ASP.NET, we are IIS and in general - Microsoft crowd. Since TMG is being deprecated, we need to come up with a hardware alternative to protect and serve our data center web cloud. Could you please advise a hardware or virtual appliance solution that can provide routing, flood prevention and smart web-site publishing (one IP - many web sites based on domain name filter) all in one. Even if it is hard to configure, as long as it covers all these features, we will invest to learn and replace TMG eventually.

  • what does it mean for MalwareBytes to find malicious registry keys but nothing else?

    - by EndangeringSpecies
    I have a machine that is obviously infected, and when I ran MalwareBytes it told me that it found some "malicious" registry keys (surprisingly enough these contained file path to currently non-existent javascript files). But, that's it. Full scan did not uncover any malicious files, or malicious hidden processes in memory. Like, maybe the (hidden?) process that for whatever reason periodically injects keystrokes (hotkeys?) into whatever currently open window. Then on another, not obviously infected, machine it found a "malware.trace" registry key but again no files or processes etc. How does this jive with people's experience with MalwareBytes? Does it usually find registry key symptoms of an infection but nothing else? Or is it a common thing to have no infection but some malicious registry keys in place anyway?

  • How do I properly check if a program is a virus/trojan in VMware?

    - by acidzombie24
    How I should check if a program is a virus in VMware? Some programs I do need admin ability to install and it makes sense. But how do I know if it's doing more than I want? Some thoughts are: How many processes open when I launch the application What is added to the startup tab in msconfig If any services are added. That's pretty much all my ideas. Even if it does something I recognize I wouldn't know if it's necessary or not. What are some rule of thumb? -Edit- What about registries, can I use that information to help? Maybe have a scanner tell me if the application I just used has messed with sections (like bootup) it shouldn't have?

  • Windows 8 isn't detecting PS3 eye

    - by JonFriesen
    I have the PS3 Eye web cam installed with drivers from Code Laboratories, which comes with a test program. When I open the test program it shows a clear picture from the webcam. Every other program does not detect a webcam. The cam shows in my device manager and as installed correctly. My question is, is there a flag or something like that I can set that will show Windows 8 that this device is in fact a camera and is working. Here is a picture of the test program that comes loaded with the drivers and the windows 8 camera app. Thanks for the help! **Here is a pic, I can't integrated because I haven't posted enough on superuser :P http://i48.tinypic.com/6qyw6t.png

  • Trouble getting started with the STEALTH monitoring package
