i-option keygen

[Guest]

hi,

im looking for the i-option keygenerator plz

[Deas]

Are you sure there even exist one? Dosn't I-option need server-auth before use?

Re: i-option keygen

It should be possible to write some kind of keygen. I mean, since it is possible to enter the license code on the display (without having internet access), it's "simply" some kind of calculation...
Anyone took a look into the printer's firmware already?

Re: i-option keygen

You need to have access to the KM License Management Server...The I-option token (white card stock in envelope) and a request code from the MFP are used together to generate the activation code. I belive you will need a KM tech or dealer to accomplish this, but if the Token offers a website to go to, give it a try. All I-options also require the additional memory chip, activating the option w/o the additional memory will induce an error code. Emujo

Re: i-option keygen

Ahh, okay. Thanks for explaining. The process of getting the request code and entering the response was already clear to me. But somehow I thought, someone already managed to reverse engineer the calculation routine.
But when you say, those options also require additional hardware than the entire process is quite useless ;-)

@oxident
Hardware for iOption is quite cheap in comparison to iOption prices - it's just SODIMM memory module.

Re: i-option keygen

Ahh, so it's only a matter of memory (and of the right activation code, of course)?
This leads me again to the conclusion that those machines must be running some kind of well known OS. I mean, the webbrowser is webkit based and as far as I know, this engine is purely for linux/unix and Windows...
Maybe we could gain root access to take a closer look ;-)

Yes.

Not so easy, OS for iOption compatible machines is VxWorks (C203-C652, BH223-BH652), but... new machines (C224-) got Linux onboard So there is a chance, but no time for fun in a week or two :/

Not so easy again - VxWorks has no root, everything works in kernel space (that's good) - accessing target console gives you administrative privileges, so you can move around all options compiled into kernel for example debugging, spawning new tasks, listing devices and accessing them and so on. But... this is completely different philosophy of OS than Linux...

Re: i-option keygen

If someone does create a key generator that works I'd be more than happy to get a copy of it

I work for the company, and only want them for self educational purposes and the answer is a big fat NO.

I'm guessing the fact that the token code comes in a sealed envelope and costs a shitload of money means not one of them has ever gotten into the wrong hands before to calculate exactly whats required to make an activation code.

Also, the license management server keeps track of all the token keys and will not allow another activation code generation from that key, until a deactivation code is supplied from the machine it was installed on previously.

Re: i-option keygen

Yeah, we can forget about VxWorks. I'm done with Windriver ;-)

But the main point is not to copy any official license token or even try to reverse the calculation based on what's inside this envelope. It's rather a way of understand how the printer checks if the entered code is correct. This might be accomplished if one gets access to the executable on the machine which is responsible of this validation.

Of course, this would be illegal in almost any country I know but there would be huge security problem if soneone might be able to modify "things" on those Linux based copiers. That's my main motivation and why I'm trying to see if there's an easy way to get root/ssh access.

Well, what can I say now?! That wasn't such a big surprise
You can guess my next question, can't you?

Re: i-option keygen

how the F did you get that ?

That's easy - just many things don't work as KM described to us, but talking about such things in public is a stupid idea.

Agree!
