A sample PIN code checker for your empeg (http://www.infodata.lu/alainp/empeg/get_passwd.tgz)

look at the readme file !

(I know, a thief can just "upgrade" a new image to bypass this "security")

Does someone know how to block the "upgrade" program (with a password by example)

Nice work Alain,

Another idea : do not show the thief the "STOLEN UNIT", but let him think the PIN was correct. Then let irDA try to call a specific number over an irDA-enabled mobile-phone every 5 minutes.
I guess someone has to walk by sometimes with an irDA enabled telephone and IR reception on. Through caller number identification you could locate the unit.

As for the upgrade program I do not think this is possible as it is in ROM.

Or another one : every PIN entered with the buttons front of the player are
invalid and only a code entered by the remote control is valid...
So the thief can try ALL codes and nothing will work (1000000 codes * 1 min (sleep 60) = +- 694 days :-)
I'm working on a better look for this program....

For the IrDA and GSM connexion, I have a Nokia 6110 and "Gnokii", but the Nokia is NOT IrDA compliant...

Does someone know how to disable IrDA (and empeg_ir) completely (without rebuilding the kernel) ? (with the use of ioctl by example)

I already made a "irdump" so I can intercept raw datas from /dev/ir, but the kernel does not include the "write" fonction... to answer to my GSM.

look at : //www.infodata.lu/alainp/empeg/irdump.tgz

I didn't tried yet... Is it possible to create a modular kernel for empeg ?
Are all the "empeg_*" modular compliant ?

You shouldn't use /dev/ir at all for bidirectional communication. /dev/ir/is only for remote controls. use /dev/ttyS2 instead.
Gnokii should work with your 6110 as it doesn't use irDA,
Hugo told me last week that it wasn't necessary to disable the irDA-driver. irDA is activated with the irattach command

Frank van Gestel

This is why I bought the 7110, apart from the bugs the neat thing is builtin softmodem, if memory serves the 5x and 6x series did not have this ? (Not to mention lack of IR on the 5x)

Perhaps by the way it would be best if the Empeg people themselves added similar functionality (pin-code) to their kernels. Though I did read something was already being done on that field.

The Nokia 6110 is a special device, it use 2 protocols :
- IrDA to print to an infrared-printer
- Nokia's own protocol to communicate between to Nokia or with Nokia Communicator program

It's still popup on /proc/net/irda/discovery.... so it use IrDA on the empeg and interfer with gnokii.
On the gnokii site, it is said that I must disable IrDA (by removing the module from kernel by example....) but empeg's kernel is not modular
And I don't want to create this modular kernel since the "empeg_*" devices are not ready for it ! (to be added on the whish list :-)

Maybe there's a trick about it....

No, you *don't* need to disable IrDA in the kernel. The IrDA in the kernel does *nothing* until you irattach it. The IrDA stack *does not drive any empeg devices* and so has no access to the IrDA transceiver on the front of the empeg until you manually attach it to the IR transceiver with irattach.

If the gnokii docs say to disable IrDA, simply don't do the irattach, and run gnokii on ttyS2 - this should work.

The empeg devices don't interfere with anything, and are not designed to work as modules as this is not applicable for the empeg - modules are more for "generic" kernels which will run on various types of hardware, not boxes with known & fixed hardware.

I think you're getting confused with /dev/ir (INPUT ONLY, buttons and IR) and the IrDA transceiver. These are totally different devices - they just happen to sit next to each other on the display board PCB. There are two IR receivers because consumer IR is modulated on a 38kHz carrier and IrDA isn't.

play the mp3 attached, something for when we get VR ?

Thanks for the answer... Now I understand the /dev/ir driver !
Unfortunately, my Nokia still don't work... I'll search another way :-)

I'd prefer my old Micro$oft Windoz 9x serial number as a code, something like : 00400-OEM-1234567-12345

Oh man... pure geek.

Maybe the VR hold up is Empeg is trying to sign Majel Barret for some VO work?

Well, surely there are some good soundbits for that on the web. I mean come on, Leonard Nimoy (Mr. Spock for you barbarians ) did the announcement on my answering machine ...

Of course, Empeg would be liable for doing so

I did once spend some time going through the entire Blakes 7 series (ALL the series) and pulling out every soundbite from Zen, Orac and Slave. It was amazing what could be pasted back together.

Unfortunately (or fortunately?) I haven't a clue what happened to all the samples. They're probably sat on a long forgotten ST506 somewhere.

Rob

Blake's 7, for you non-Europeans was like the UK version (which was first btw?) of Star Trek (people are going to hurt me for saying that). It is still one of the best series to come out of the UK.

okay pop quiz, what was the name of Blake's Ship in Blake's Seven ... Both the name Blake gave it and its REAL name!

Oh and Avon was the coolest of them all!!

P.S. Rob : Look here

Liberator, Deep Space Vehicle 2. (Ok so I cheated to find out the second one)

Oh and Avon was the coolest of them all!
"I'm going to live forever or die trying"

Deep Space Probe 2 I thought ... Hmmm, pretty sure it was probe ...

Okay half a cookie for you ...

Do you remember the episode where one of the smaller probe ships turned up?
(it looked like the central portion of liberator).


The other ship they used was Scorpio (the computer on board was Slave) - they fitted a super drive and activated it frying the designer in the process.


The main difference between B7 and Star-Trek was that B7 was failed anti-heroes fighting a loosing battle against superior forces in an 'aquired' ship.
