Hi geekmaster,

To run linux commands on your Kindle without a jailbreak, you must exploit a security loophole somewhere in the Kindle,
But that sounds like a hell lot of work - for instance the busybox comes with an implementation of wget that might be prone do that 'serverside-generated-names' bug, but does WebKit make use of wget and is it run with extended privileges? Well, question best to be answered from 'inside', I'ld say.

You can study the different Kindle 3 jailbreak source code (yifanlu's or NiLuJe's) if you want to learn how they work and what Kindle 3 bugs they exploit.
Which one do you prefer? Only had a look at yifanlus sources for now: http://yifan.lu/p/kindle-jailbreak/

Allthough the published src is 0.5.0 and the hack I need is 0.5.1, I think the 'magic' part is the hook.dat which foists any arbitrary bin upon the kindle!?

Actually I'm afraid I don't dare to set up the required toolchain to compile myself, chiefly due to lack of time -- but if you could provide some nicely written HOWTO on that topic, I'ld be glad to read...

Greetings

Kim
