telnetd / gaining root

I'm not quite as gutsy as igorsk when it comes to publishing actual reverse engineering tools, but this evening I managed to get a telnetd onto my K2.

If you know how to build update packages, it should be straightforward for you to knock something together.

Did you just create an init.d script for your telnetd and link to it from /etc/rc5.d? I tried this (and a couple other methods) with a script that just ran netcat to listen and spawn a shell, but it didn't work for some reason. I'm working on crosscompiling telnetd now.

And no, I don't have any intention to do things Amazon wouldn't like. They must not care too much anyway, because they apparently did nothing to make the K2 any different/harder to hack than the K1 (which had published info on it!)

see if debugMessages shows you what happened when your update ran. (But you don't need to build your own telnet. you can use a statically linked busybox built for android or maemo.

I haven't noticed anything called debugMessages. What's that?

I'm just interested in getting custom screensavers. I don't care about getting free internet. Just a Java developer interested in tinkering with my Kindle. I go a compiled andriod busybox, but having problems creating the update*.bin file.

Another member has already come up with a hack for screensavers on K2. See post #53 of this thread.

There is a different set-up for K1. Those instructions are here.

I was wondering if one can exchange the font and get unicode support after gaining root. Any idea?

The device supports unicode already and its the font that they are shipping missing the glyphs that you want. (I know minor difference but everyone seems to forget the difference between supporting unicode and the glyphs required to display the characters)

Obviously its possible to hack the device and replace the font, just remember that font itself is a copyrighted work, and Microsoft didn't spends years + tons of money to make a font for you to use it in the Kindle =D

Copyrighted doesn't mean unusable. Microsoft's EULA for Times/Arial/Courier gives you the right to install all you want, wherever you want. Which is why they're freely downloadable.

Though MS is not even close to being the only source for Unicode fonts.

I have some ideas about getting proper and free fonts onto the Kindle. If I can make it go, I'll package an "upgrade"

I should mention that whatever package you dream of releasing, indicate the change in the version string file; otherwise, customer service has no idea that someone reports a problem with all these misc. packages installed. Costs both the dev + qa griefs on hunting ghosts.
