  1. I need to know this before I start onto this - will Ubuntu boot ok from a bootable flash drive? I know how to make the drive bootable, that's not a problem.

    Anyone who knows, post it.

    If you are wanting to boot a NetBook there are already images available:

    http://www.ubuntu.com/getubuntu/download-netbook

    If you are wanting to convert a CD image to USB then you can use the tool included on the LiveCD (have to boot CD on another machine) or use the 'easy to use' Unetbootin:

    http://unetbootin.sourceforge.net/

  2. Anyone know if combining these three things is possible?

    What you want chocolate, a surprise AND a toy..... you greedy little bugger! ;-)

    You might be interested in Linux MCE (http://linuxmce.com/) which does a whole-home system. There was an interview on TLLTS with the lead developer a while back.

    You should also remember that distrobutions like Muthbuntu are complete systems, and you can install want ever other software you like on them. ZoneMinder could be used to do the security aspects of what you want.

  3. It sounds like the 'sources.list' (/etc/apt/source.list) file may have become corrupt, this tells they system where to get it's updates from. Check that looks sensible, and if so do a 'sudo apt-get update' which should poll the servers to find out about new packages.

    If that works, a 'sudo apt-get upgrade' should pull down and install new packages.

    Cheers,

  4. Should I consider the beta Lynx instead? I see it's going live in 9 days. (On the other hand, 9.10 is _mostly_ working after lots of blood, sweat, and tears, so I'm very hesitant to wipe and install a different version when I'm so close)

    Either way, thanks a ton for the help so far, that wifi tip alone was extremely useful!

    I'd suggest getting a copy of the beta2 or wait a few more days for the RC and try that as a 'live CD'. If the problem is solved with that, then you can either install that from CD or just wait a week or so (till 29th) and do a 'distro upgrade' on what you already have.

  5. When it had Windows 7 stock on, it was running fine. Now, it is randomly freezing within a few minutes of booting up. It might be related to using the mouse, if I just have it sitting downloading stuff via apt-get it works fine, but if I'm browsing the web or anything it tends to freeze after a couple minutes. (Currently via ethernet, still working on getting wifi working)|

    Sounds like a problem with the graphics chipset/X driver. Looks like the X201 has Intel HD GMA, which apparently has issues in the recent past.

    http://www.uluga.ubuntuforums.org/showthread.php?t=1402612

    Which version of Ubuntu are you running?

    Re WIFI:

    Intel Centrino Ultimate-N 6300 : supported by the iwlagn driver

    Intel Centrino Advanced-N 6200 : supported by the iwlagn driver

  6. Has anyone had any success? If so, what's your setup?

    Only tinkered with a bit, but there's an app called WebCamStudio (http://www.ws4gl.org/) which can stream screen caps along with video/audio from webcam.

    What sort of resolution are you attempting and is it 'live or Memorex'.

  7. anyone know much about bluetooth cracking/hacking...

    one of my personal concerns with the security of BT is the fact that i use a BT keyboard on my home PC connected to my LAN...

    As mentioned there is a new-wave of research in Bluetooth, mainly driven by the availability of the USRP/USRP2.

    At this year Shmoo Con there was a presentation specifically on Bluetooth Keyboards, which you might find interesting.

  8. I don't really think that the integrated program is a Java application I'm about 80% that it was developed in C or C++ don't you think so mungewell ?

    The MC35i has a java engine, and it seems unlikely that the main code of the modem was altered as it would affect certification on the module. With the applet the developers would have just used an IO protocol to match the rest of the system, which may have been coded in C.

    I'm guess you weren't involved in that part.... but hacking the hell out of it is OK ;-)

    In fact, after establishing the serial port connection with my modem, some AT commands run automatically after a while an encrypted program show on the hyper terminal screen after the end of the program the hyper terminal screen shows "ATO" commands and then "OK" that is automatically repeated after each 5 seconds.

    These are probably just a custom protocol used by the applet. When the thing first boots do you see '^SYSSTART'? On the TC65i this is output and then the applet autoruns and takes control of the serial port. Stop the applet and you will be able to type real AT commands.

    If you were to run 'Free serial port monitor' on the com port and then run the autostart_off application, you might see (for example) something like this ;-)

  9. There is a little application/proceedure for stopping autorun. I'll see if I can find a version in the wild.

    Mungewell.

    From http://www.onegsm.ru/files/Siemens/tc65_java_ug_v01.pdf

    10.4.2 Switch off Autostart

    To switch off autostart functionality there are two possibilities:

    • AT command at^scfg

    • tool “autostart_off.exe” (included in the Installation CD software)

    To disable the automatic start of a user application in a module these steps have to be done:

    1. Connect the module to the PC

    2. Make sure, that the module is switched off

    3. Start the Autostart_Off program

    4. Select the COM-Port

    5. Press the “Autostart Off” button

  10. I said before that I'm not even able to introduce AT commands after an internal program in my module is lunched automatically

    Missed that snippet of information (helpful if people cut down the quotes in replies to the relevant bits). Sounds like it is auto-running the java applet, do you have the serial or USB interface to the module?

  11. My modem is not used to connect to Internet! it's composed of a GPS module and the MC35i GPRS module to send data via GPRS my modem is used for fleet management purposes. So I need to send data from my modem to the fixed IP address of my own server now the IP address is fixed to another server (my ex provider) and i need to change it to my new one to test my own application to communicate with that modem!

    hope now my problem is neat and can be understood :mellow:

    You don't say where the 'smarts' of your application lies - is it a Java Applet or is it a micro/PC throwing AT commands at the MC35i?

    If it is the applet, presumably this has a configuration store somewhere on the filesystem or pulls it from a internet server. Who in their right mind would hard-code values these days? Do you have the applet source?

    If it is the micro, you will need to find the configuration of that.

    Cinterion are particulary tight lipped with their datasheets. If you can get an AT interface you could try to test the general connectivity with something like:


    AT^SICS=0,conType,GPRS0
    OK
    AT^SICS=0,apn,"GPRS02.point.de"
    AT^SICO=0
    OK
    AT^SISX="Ping",0,192.168.1.2,4,2000
    ^SISX: "Ping",1,0,"192.168.1.2",1043
    ^SISX: "Ping",1,0,"192.168.1.2",586
    ^SISX: "Ping",1,0,"192.168.1.2",531
    ^SISX: "Ping",1,0,"192.168.1.2",415
    ^SISX: "Ping",2,1,4,4,0,0
    ^SISX: "Ping",3,1,415,1043,643
    OK

  12. Is this even possible?

    Jamming would work by overpowering the GPS frequencies so that receivers could not lock onto the satellites. This would be illegal (deliberate interference) and therefore ill-advised.

    The US military can and does selectively weaken the accuracy of the decoded location for particular locations on earth, in these locations you need access to a military receiver to decode the P-Code and get good positional accuracy.

    The L1 frequency is the one used by most receivers, this is supplimented with L2 on survey grade receivers and allows them to predict/model the atmosphere better.

  13. Windows by itself does not support serial terminals, you would have to run an additional server to accept the incoming connections. You could do this with Cygwin and Getty. This will get you a text bash (or other) shell running on the host Windows machine in which you can run unix like commands.

    Another option for you is to bring up a TCP/IP connection between the two machines. This is rather slow/quirky but does work. You can run telnet, ftp, ssh, vnc, etc over such a link. A direct link between the two machines would use SLIP or PPP, which can be started via DIP/PPPD on a Linux machine or under Windows 'PC Connections/Direct Connection'.

    Here's a link to a how-to which might give you some ideas on how to get started:

  14. from the datasheet it looks like i can transmit on different frequencies (87.7-88.9 & 106.7-107.9) by manually setting pins on the chip but it doesn't say anything about transmitting between those 2 ranges, BUT digikey tells me that frequency is 76MHz ~ 90MHz, 87.5MHz ~ 108MHz

    There's a more complete datasheet here:

    http://www.rohmelectronics.com/downloads/products/focus/audio_lsi/bh1417f.pdf

    The last page describes the possible frequency selections.

    If that's not good for you, you could try something like:

    http://www.shopxscargo.com/product_catalogue/cat_product_details.asp?category_id=6&product_code=26340&sub_category_1_id=12&category=Accessories

    Complete control of frequency, plus you can recharge your laptop ;-)

  15. unfortunately my device is a v.5 device

    The support database for DD-WRT confirms that this is a 'usable' device:

    http://www.dd-wrt.com/site/support/router-database

    This presumably means that it is also usable with OpenWRT, which has a lot more flexiblity in functionality. However the small memory will probably mean that you won't be able to use it for Asterisk (might if you strip out all the GUI packages).

    Firstly since it is vxworks based you have to kill/remove that and then download the 'micro' image. Once you get that running have a play at installing new packages.

  17. http://blogs.zdnet.com/hardware/?p=6655&tag=nl.e589

    While the data on the drive is indeed encrypted using 256-bit crypto, there’s a huge failure in the authentication program. When the correct password is supplied by the user, the authentication program always send the same character string to the drive to decrypt the data no matter what the password used.

    I suppose this was done to allow changing of the passphrase.

    But...

    What’s also staggering is that this character string is the same for Kingston, SanDisk and Verbatim USB flash drives.

    Complete fail!!!

  18. So what are flag type operations?

    I guess I should have said 'bitwise'.

    Where a 8/16/32 bit value is used to store multiple 'things', one in each bit. This might be bit representing the state of digital input/output of a microcontrol, flags in a config register, or the state of the machine's processor.

    The later is used in the assembler code to store things like Z-flag (zero), N-flag (negative), etc, which can be compared after addition/subtraction is performed. For example in psuedo code

    LOAD A 0x10 - load '0x10' into register A

    SUB A 0x10 - add '0x10' to register A, will set Z-flag is answer is zero

    BEQ ... - branch if equal to zero...

  19. I really want to know how to use it, what it can do with it, how to program with it and edit things with it.

    You need to think like a computer.... the real benefit is in the logical operations (AND, OR, XOR) and shifting.

    Base2 is great for FLAG type operations (if you've ever played with assembler), but can prove awkward with multiplication/division (unless with a power of 2 where it is a shift).

  20. I would recomend 'The art of electronics' (writing out the first 3 chapters got me through the 2nd year of college). It's a bit pricey, but is a common student book so you might find a copy secondhand somewhere.

  21. Hallo, I need a program or something like that to transform sound waves in zeros( 0 ) and ones ( 1 ) - ASCII codes please help :rolleyes:

    Not sure what you are asking, but if you wanted (say) a 16bit value for each sound sample you could use a combination of SOX and something to dump the output (maybe hexdump can do it).

    SOX (http://sox.sourceforge.net/) can convert between many audio file formats, convert to raw.
