  • Digitally Signed Malware on the Rise

    Brought to the forefront in 2010 with Stuxnet, the infamous worm aimed at sabotaging industrial infrastructure, the use of stolen digital certificates is relatively new. Stuxnet's creators digitally signed its rootkit components with stolen certificates from JMicron and RealTek, a pair of semiconductor manufacturers. The worm's existence and complexity caught the security community by surprise. In fact, many researchers predicted that malware creators would begin adopting the same technique to work around driver signature enforcement employed by Microsoft in its 64-bit versions of Windows V...

  • Is there an Ubuntu alternative to iExplorer (formerly iPhone Explorer)?

    - by nerdabilly
    I'm trying to view the entire contents of my iPhone in Ubuntu 10.04. I'm able to mount and view the digital media folders, but I'm looking for behavior more like the Mac/Windows iExplorer app that will list the /var folder as well as Applications, etc rather than just making it look like an external filesystem. I've found a few options that require jailbreak but I'd rather not go that route if it's at all possible. Thanks!

  • certificate for website login

    - by Mario
    Not sure if this belongs here or at serverfault... I've seen websites where, to login to the website, requires a digital certificate to be installed for the user logging in. As far as I can tell, this certificate is in addition to the website using an SSL certificate (https) I'm just looking to be pointed in the right direction on how to code for this (apache / php hopefully), who issues these certificates (must it be a trusted var or can I ?) or even what to search for via google. -Mario

  • Wifi problems with Ubuntu 13.10

    - by Sparrowhawk4
    I should probably say straight off that I am brand new to Ubuntu. I installed 13.10 alongside Windows 7 a couple of days ago and I've managed to clear up all the little problems, apart from with the wifi. My internet is fine using an ethernet cable. I can connect to the wifi, and it tells me that the signal is good, but for the vast majority of the time I can't load anything, and system monitor tells me that I am sending and receiving nothing. The problem is somewhere in Ubuntu. It works fine on Windows 7, my Android phone and all of my flatmates laptops. I know I'm not the only one with this problem, but the fixes I've seen either don't work or I don't understand them enough to carry them out. Help?

    Why my computer runs too slow when I install Ubuntu or any other Linux (Debian works better than other distros), but with windows works fine...? My configuration is: Processor: Intel Celeron CPU 1.70GHz Graphics: Ati Radeon 9250 128 MB HD: Western Digital 120GB RAM: 2GB DDR1 Motherboard: MSI (MS-6566) Is there anything unsuported by Ubuntu, or any Linux.

  • How do you reset a USB device from the command line?

    - by Casey
    Is it possible to reset the connection of a USB device, without physically disconnecting/connecting from the PC? Specifically, my device is a digital camera. I'm using gphoto2, but lately I get "device read errors", so I'd like to try to do a software-reset of the connection. From what I can tell, there are no kernel modules being loaded for the camera. The only one that looks related is usbhid.

  • Dual VGA monitors with Quadro FX 580?

    - by dentrasi
    I have a machine with a Quadro FX 580 card (DVI and two Displayport). Attached to it are two 19" Acer screens, which are both (annoyingly) VGA. The first one works perfectly, with a DVI-VGA adaptor. The second one doesn't work. It's got a VGA cable, which goes into a VGA-DVI converted, which then goes into a DVI-Displayport converter. Initally, I was getting 'Cable Unplugged' on the screen, and it couldn't be seen by Windows or the nVidia control panel. After swapping the VGA-DVI adaptor (which works perfectly on another machine), Windows can now see the monitor. The nVidia panel sees the model and native resolution, but I get a constant 'No Signal' error. Switching to the other Displayport makes no difference. I suspect that the card is seeing a DVI connection plugged into it (nVididaCP shows the monitor as having a DVI connection), and it only sending out a digital signal because of this. Does anyone know of a solution (other than trying to get a Displayport-VGA adaptor), or of a way to force the card to see it as VGA? Thanks, ~Dentrasi

  • Apple video adapters: Mini-DVI to DVI + DVI to video?

    - by Ken
    I have: a Macbook (which has Mini-DVI output) an Apple Mini-DVI to DVI adapter (so I can hook up my Macbook to my DVI LCD) a Mac mini (which has DVI output) I see that I can get a DVI-to-Video (s-video and composite) adapter from Apple that will let me hook up my Mac mini to my TV set (which has only component, s-video, and composite -- nothing digital). So far so good. Question: Will that same adapter also let me hook my Macbook to my TV? That is, can I hook Macbook - Mini-DVI to DVI - DVI to video - TV set, and see picture? I know there are digital/analog/integrated variants of DVI, and it's not at all clear to me what pins these things have and what signals they're sending. One website I found suggested that it would work, and another suggested that it wouldn't even physically connect. So I'm looking for, ideally, someone who's actually tried it, or has these adapters sitting around to try. I know I can buy 2 adapters (Mini-DVI to Video, and DVI to Video) to do this, but at $20 a pop I'll avoid that if at all possible.

  • Windows 7 Not Recognizing Camera Nor iPhone as Camera

    - by taudep
    I've been struggling with this one for a few days. I've recently upgraded an older computer to Windows 7 Home Premium. Neither my digital camera (A Canon SD1200IS) nor iPhone are ever detected as cameras, nor ever show up as accessable in Explorer. With the Canon camera, no driver is required. It's supposed to work with the default Windows 7 drivers. However, in the Control Panel's Device Manager, I'm always seeing a yellow icon next to the "Canon Digital Camera" device. I've uninstalled the device and let Windows attempt to reinstall, but it can never find a driver to install. With the iPhone, it's very similar. One big difference, though, is that iTunes can see the iPhone and back it up, etc. However, again when I go to the Device Manager, there's a yellow icon next to the iPhone. I've uninstalled iTunes, reinstalled, rebooted, deleted drivers, and let Window try to reinstall the driver, but it can never find the driver. So there seems to be some correlation that my machine can't detect cameras properly, and that it might be even a lower-level type of driver I'm struggling with. I know that USB however, does work, because I have have an external drive hooked into the machine. I've gone through the web and tried two hours worth of fixes, without success. I feel like if I can get the Canon camera detected, then the iPhone will be on it's way to being fixed too. BTW, I couldn't really find anything of use in the Event viewer. Any and all suggestions welcome.

  • Set up WLAN in 3-level house

    - by Balint Erdi
    I'm having a hard time setting up the network in our house. It has three levels (basement, ground floor, first level). The WLAN is set up by an ASUS RT-N12 router which provides perfect coverage for the ground floor and the basement. However, I set up my "home office" in the basement where the signal barely arrived. So I purchased a TP-Link TL-WA901ND (300 Mbps) Access Point which I set up in the other corner of the ground floor to expand the ASUS router's range. I used the AP's Repeater mode for that. The distance between my computer and the TP-Link AP is 6-7 meters. There is a staircase going down from the ground floor to the basement so there are no solid walls between the computer and the AP. This setup mostly works (I am writing this from the basement) but it is not reliable (the signal strength sometimes goes down to ~40% of the max) sometimes so I wonder if I am doing it correctly or if there is a better way. Screenshot of the router's and the AP's dashboard screen follow: Any comments on what I am doing wrong or hints for improvement are appreciated. Thank you. UPDATE Tried one more thing, setting up the TP-LINK AP in Access Point mode. That way, I can make it use a different SSID. I enabled WDS/Bridge so that it expands the range of the ASUS router (see screenshot). That does not work, either, if I connect to the network set up by the TP-LINK device (PELSTER-2), I can't reach the external network (the Internet). It seems the problem always comes back to this, the TP-LINK does not have access to the external network, whatever its mode of operation.

  • Can one really fry a monitor by setting the wrong HorizSync and VertRefresh?

    - by rumtscho
    I've encountered this problem on several different systems with several different monitors: a monitor functions perfectly under Windows. I install a Linux and the max resolution is at some impossibly low value, mostly 640x480, changing it in Xorg.conf doesn't work. The X.org log file then shows that the driver cannot determine the correct refresh rate for the monitor, so it ignores everything in Xorg.conf and just loads in some default minimalistic mode. Googling the problem leads to an easy solution: set the HorizSync and VertRefresh in Xorg.conf, and everything works. The problem seems to be a common one, and I've seen dozens of results recommending the solution. Each of them contains the warning that you should use the value ranges provided with the monitor. Because if you don't, and your video card sends a signal with the wrong refresh rate, this can damage your monitor. Of course, you don't have a user manual for your monitor any more. If you are lucky to find one on the attic or on the net, it doesn't contain any information about the supported refresh rate. So you just type in the value suggested in the solution description, which varies wildly depending on your source, and cross your fingers. You restart, and... ... you've set the wrong values. So the monitor shows a short message like "input signal out of range", and you do a hard restart, repair your Xorg.conf in recovery mode, and everything is fine, including your monitor. So does this warning reflect a real possibility, or is it just a geeky urban legend? Or is it something which used to happen in the past, before manufacturers started protecting the monitors against it? Is it technically possible with every monitor technology, or is it maybe something which can only happen to a CRT? If you think that it's true, why? Have you ever witnessed a monitor die from the wrong refresh config, or have you read of it in a reputable source?

  • Will just a couple of thermal "trip" shutdowns typically damage a CPU?

    - by T.J. Crowder
    The short version If a CPU gets so hot that the system turns itself off because of a thermal trip signal just a couple of times, is it likely that the CPU will be damaged? Or does the trip do its job, turning it off before the CPU gets damaged? (This is with all default settings in the BIOS; I haven't raised any temp thresholds or overclocked anything.) The longer version I just got this Intel Atom D510-based fanless system, installed a 2.5" mobile SATA drive and two 2GB PC2-6400s, closed it up, and having checked everything was recognized in the BIOS, set about installing Ubuntu. After a couple of false starts related, I think, to the external DVD drive I was using, I got the install happily running along. About three-fourths or so of the way through the install, having been running less than an hour, the machine turned itself off. I was actually out of the room at the time, but when I came back and turned it back on, it said it had shut down due to a thermal event. I went into the BIOS and saw that (at that point, having just been turned back on after a couple of minutes off), it was running 87C. As near as I can tell from Intel's docs (PDF here), the max "junction" temperature for the CPU is 100C and it will raise a THERMTRIP signal at 125C. Yowsa. Presumably there will be some back-and-forth with the vendor on this, I'm just wondering whether letting it get that hot a couple of times is likely to end up damaging it.
