ah! cool edited my post! In case someone starts sueing me over it >

NiLuJe thanks! See elsewhere on this subforum for me praising you even more

mntroot rw
passwd
new password; need to type it 2 times.
mntroot ro

OH question: do I need to "mntroot ro" everytime I quit ssh? Or is it "safe" to leave it rewitable? (safe as in it not botching things up when I use my kindle and/or safe as in others being able to access it)

I'd advise against leaving the rootfs in a rw state, yeah, you never know what might happen .

But you should almost never ever need to switch it to a rw state in the first place, anyway...

Could someone explain how to remove a certain folder from the root of my Kindle 3 using USB Networking? Instructions need to be relatively simple - programing is not my area of expertise!

safety 1st. I agree. But my mind sometimes tends to forget the important instructions and to keep focussing on anything else

1. set the system to write:
mntroot rw

2. go to the directory that has the file.
cd {directory}
(change {directory} to what you need).

3a. remove the file you need with
rm {filename}
change {filename} to what you need.

OR

3b. if you want to be a bit more safe make a backup with:
mv {filename} {filename}.backup

4. set systeem to read only:
mntroot ro

5. and exit with:
exit

Just a friendly warning though...

Just make sure you think before you press enter when using mv and rm commands.
That includes to wait for someone to confirm that what I typed is correct (ie. never trust someone on his blue eyes when telling you to rm something and always wait for a confirmation).
Because... NO ONE takes any responsibility for any of the commands and if something gets broken it is on you

You don't need to switch to rwfs to access /mnt/us (the userstore) or /var/local

(ie. in your case, Stonecold, just
mv /mnt/us/usbnet/auto /mnt/us/usbnet/DISABLED_auto
)

You can check the result with:

lsusb | grep RNDIS

This should show something like:

Now you should be able to ping your kindle with:

ping 192.168.2.2


and ...
telnet 192.168.2.2 now gives me...

disi! Your steps and my knowledge on Ubuntu got me into my kindle *O*
Sounds really good. I have dualboot and tried to connect the kindle on my Gentoo installation, but gave up after a while :/
Seems Ubuntu has some quirks to automatically configure the usb port

(I do not use hald, I guess that's the main problem with Gentoo)

You're obviously missing something.

just a quick question (and also my first post here, though i have been doing a bit of lurking), is there any disadvantage to changing the root password? i.e. is it set to whatever it is for a good reason, like for updates?
I have ssh going via public/private keys, which i normally use between machines anyway, but I'd like to know the password, and running the shadow file through a cracker did not find anything (its obviously too long for brute force cracking).

Can't think of anything relying on the password being untouched, AFAIK, but given that I use shared keys, I really can't think of a good reason to change it either .

3.0.3 kills the test files

After the upgrade to fw 3.0.3 the fabled factory test files have disappeared. Of course the files can be put back - and everything works again, the Java components are compatible - but maybe some of you wanted to know this.

Check if you have the file /test/ebook/lib/testtools.jar
Check the file /opt/amazon/ebook/bin/start.sh for the line: testlibdir=/test/ebook/lib

If both are fine then it should work.

If you plant the files on the exported USB drive, then it won't work; you need to place them in the root directory. First you need to jailbreak, get a shell, mount the root read-write, copy the files, mount read-only, reboot. You could ask someone here for step-by-step instructions, but nevertheless you should start by jailbreaking the device (plenty of help available on this topic).

mntroot ro
And that's all of it!

The instructions:
1) Copy jb_install.sh into kindle's main storage
2) ;debugOn
3) ~exec /mnt/us/jb_install.sh
4) No reboot needed
is it possible to make a script that could reset kindle 3 to factory settings? i can't access my settings page where resetting to factory settings could easily be done. my ~exec command works so maybe you could help me reset my kindle using a script?
