  1. you CAN use a television with a QAM tuner, or get a television, or set top box such as a TiVO that uses cable cards, and rent a cable card from your cable provider...

    You can also use a Cable-TV card in you PC, but be aware that many cable providers wrap the Free-View-Channels up in their encryption scheme. Look for the phrase 'clear-qam'.

    If you have decent local Over-the-air broadcast you could get a basic selection of channels via an aerial.

  2. I am trying to connect two virtual machines in VMware Player to teach myself how to use metasploit. As such, I want to make sure the two virtual machines are only connected to each other and can't actually get online. I'm very new to metasploit and I want to make sure everything is contained.

    AFAIK the virtual serial ports are only to connect to/from the host machine and the VMWARE client machine. I did use a app for bonding/looping back serial ports (which would run on the host machine), but can't remember the name of it at the moment.

    What you probably want to do is use the 'virtual network editor' and set a network segment that only the 2 virtual machines are operating on. This way they can scan/probe each other without affecting the host machine, or other real machines on your LAN.

  3. It missed the question - "which package manager do you prefer?"

    and suggested my old crap hardware might be too slow for Debian/Ubuntu/etc....

    Sorry if I'm a 'Deb' zellot, I got badly burned by 'RPM' a (fair) while ago and am too stubbon to change/give it a second chance.

  4. Kind of a side step, by I meant to write this up somewhere:

    I managed to get a cheap PCIe x16 GFX card ($25 8600GS) working in a modified PCIe x1 socket with some 'hardware' skills. Relevant here because this card is CUDA capable, and I intend to do some stuff with it a later time.

  5. I'm asking the question because it would be a really nice cheap way to adapt all sorts of controllers to the wii.

    It may be possible to 'pretend to be' a Wiimote, however it may be hard as the console might attempted to read all sorts of trival parameters from the remote (such as reading the camera data) which wouldn't normally be required for your application. Faking up the BlueTooth interface on Linux should be fairly trival, however the devil is in the detailed operation.

    So far the best resource I have found is the WiiBrew site:

  6. My Laptop's Intel card (82852/855GM) is a nightmare under 10.04, practically unusable - not that it helps you... I'm just bitching.

    You could drop to using the VESA driver, but would loose all the 3D acceleration. I find that my display is only flickery at particular resolutions (using the VGA output), so you could try alternates screen sizes.

  7. Can anyone recommend a good XTerm client? Would Putty be a good one? What about Cygwin?

    Your terminolgy is a little off... I presume that you are asking for a Xserver to run on a Windows machine, which would allow you to run X applications on a remote (unix) machine and view them on the Windows machine.

    Cygwin is OK, I use it at work (mainly for a bash shell and familiar command line tools), and can be used in a rootless mode so that X applications are intermixed with the native Win32 apps. It does have a few problems though, and some apps really don't like it.

    Another option would be Xming (https://sourceforge.net/projects/xming/), which I haven't tried yet.

  8. I'm trying to figure out if the mysterious unpopulated part of the board is for EJTAG.

    Nope. ;-)

    My best guess would be that alternative tuners/demod cards can be fitted to work with DVB-T, Digital Satellite, etc... The main processor can handle transport stream and would most likely control the tuner via I2C. Multiple transport streams would be unused in dual tuner PVRs to allow for the recording of a program (which might be on a different multiplex) to the one being watched.

  9. The squashfs image was too big compared to mine, so it failed to flash. I first tried replacing the video player app that was much larger with the one I had originally, but then I wouldn't get any video. I then tried using my original firmware, but replacing /bin, /usr/bin, /usr/sbin and /etc with the one from the online backup (which had a working telnetd). I flashed it... and...

    Congrats!! and now a 'handy Mungewell hint'....

    If you are mounting the embedded disk image and changing stuff, you can find that the 'old stuff' is still on disk and lessens the amount of compression that can be done on it (I found this when playing with Linux-VR on MIPS PDA a while ago, so might not be applicable now).

    By creating an empty disk (with dd if=/dev/zero of=...) and then taring/untaring the altered disk into it you can be sure that there is no cruft left behind.

    Which graphics system (X11, SVGALib, etc) are they using, which media player, etc....?

  10. Does anybody know if there exists a way of physically placing a device on top of the SOC that would fit directly on the 256 pins and allow you to more easily probe them, or connect them to a serial port?

    For the size device that you are looking at, these would be HUGELY expensive. My suggestion would be to looks for info around the web, there was some suggestion that there was a Telnet port active on other variants - did you try portscanning it?

    If you are pretty sure that the ASC pins are not connected on your board you could target the unconnected ones and probe with the input to a FTDE adapater (so that you can see any serial activity on PC when board is powered). You will also need a ground connected to board ground.

    Serial data is pretty destinctive.

  11. The bootloader code suggests the usage of UART 16550C, and also an optional YAMON interface.

    Most modern SOCs have standardised peripherals built into the chip, so this will be refering to the on-board UART rather than an external device.

    If you have the boot loader you may have important information about the memory interface configuration. If you can get to the JTAG port, you may be able to configure the memory interface by hand and simply read out binary from the flash chip.

  12. I took much better pictures this time, I uploaded them here:

    Could have warned about the 47MByte... ;-)

    So this is you media player thingie. Obviously the main processor is the largest (RTD1262) luckly for you it is a Quad flat pack as you can actually get probes/wires onto the pins.

    GL850: USB 2.0 4-PORT HUB CONTROLLER

    JM20330 is a single chip solution for serial and parallel ATA translation.

    Do you have a IC name/number for the one in IMG_3082?

    I'd check datasheet pinout against older RTD1261 (probably same/similar) or maybe try to trace tracks from other image:

    http://rtd1261.wikidot.com/internals

    Serial will be LV-TTL on chip's pins. Check the supply rail (3.3V or 2.8V) and use a USB/Serial convertor such as:

    http://www.robotshop.ca/sfe-lilypad-usb-link-mini-b-1.html

    As well as serial ports, you could track down the JTAG pins. Depending on what processor is used inside this beast these can give 100% control of I/O ring and if you are lucky of the processor it's self.

    Have fun,

  13. I find it very interesting that all the 'WebM is crap' comments point to the same posting by the H264 developer, I'd be really interested with what others have to say about the technical details of the format.

    It seems that the MPEG-LA is going to be going on the offensive with this one, probably claiming that it must infringe of one of their patents (as nobody else could possible 'invent' a codec other than themselves).

    As far a I can see, the one failing of WebM is that they have excluded all other items from the WebM container, which means that it is not possible to subtitle WebM content - hardly good for international videos/content.

  14. How secure is VOIP-to-PSTN traffic? For example, if I send a fax to someone's VOIP number, what security practices do VOIP companies have in place to protect conidentiality? Does anyone have any educational resources?

    It depends on your VoIP provider. There are some encryption protocols which can secure the data portion of the call, providing endpoint to service provide protection, however at the point it drops onto the PSTN it is as 'in the clear' as any other normal phone call.

    For most free, or low cost consumer services I would expect the security to be little to none. However it is worth noting that the 'voice stream' generally (not always) travels directly between the end-points, so applications like Zphone (http://zfoneproject.com/) can successfully encrypt VoIP calls. Zphone acts a 'bump in the wire', and auto-magically inserts itself in the network stack of your computer, and has been ported to some devices.

    In terms of sending a fax from (say) your scanner to a remove VoIP based number, you may be able to provide some level of encryption. If you are using a remote service, I suspect there would be no encryption applied.

  15. Isn't it hosted at google? Also, the picasa page says they give 1 gig of free storage only. By "full control over my data" I first mean that I don't want my data hosted in the cloud. This data is too important to risk having it hosted elsewhere. I want to host the data by myself and make my own backups regularly.

    Not sure what you mean by 'This data is too important to risk having it hosted elsewhere', using a cloud based system might actually mean that the data integrety would be better. However, I do see the benefits of keeping images/information out of the eyes of Google et all. Ultimately you will have to trust your hosting company (even if you have a VPS) not to 'loose' backups and keep then secure.

    Lots of the CMS software have plugins for image galleries, which are often '1 click installs'. Limiting viewing to specific users/groups is possible.

    I found a handy 'try it out site' if you want to play with any of the (many) open source CMS solutions:

    http://php.opensourcecms.com/

    Another benefit of a hosted solution is that that will (should) handle keeping the installation up to date. There are some headaches with hosting your own stuff on a VPS, getting pown'ed is just one of them.
