I've been trying to SSH into my new Kindle Paperwhite 2015, which was jailbroken using knc1's great tutorial I found
here. After jailbreaking, I updated my firmware to 5.8.1 and installed KUAL and USBNet for 5.X, along some other KUAL extensions, and tried to SSH into my Kindle.
But I didn't have the passwords for
root. I tried the default passwords, the Kindle password generators (including KindleTool), and none of them worked. So I resorted to kterm to dump
/etc/passwd and
/etc/shadow, so I could brute-force it with Jack the Ripper.
Turns out, my
/etc/passwd looks like this:
Code:
root:x:0:0:root:/tmp/root:/bin/sh
daemon:x:1:1:daemon:/usr/sbin:/bin/sh
bin:x:2:2:bin:/bin:/bin/sh
sys:x:3:3:sys:/dev:/bin/sh
sync:x:4:100:sync:/bin:/bin/sync
operator:x:37:37:Operator:/var:/bin/sh
sshd:x:103:99:Operator:/var:/bin/sh
messagebus:x:92:92:messagebus:/bin/false
nobody:x:99:99:nobody:/tmp:/bin/sh
default:x:1000:1000:Default non-root user:/dev/null:/bin/sh
framework:x:9000:150:Framework User:/tmp/framework:/bin/sh
guestuser:x:1002:1001:Guest user:/tmp/guestuser:/bin/sh
And my
/etc/shadow looks like this:
Code:
root:!:10933:0:99999:7:::
daemon:*:10933:0:99999:7:::
bin:*:10933:0:99999:7:::
sys:*:10933:0:99999:7:::
sync:*:10933:0:99999:7:::
operator:*:10933:0:99999:7:::
sshd:*:10933:0:99999:7:::
messagebus:*:10933:0:99999:7:::
nobody:*:10933:0:99999:7:::
default:!:10933:0:99999:7:::
framework:!:14033:0:99999:7:::
guestuser:!:16506:0:99999:7:::
Every password for every account, including
framework, was disabled! That's why I couldn't login!
I didn't want to touch things I don't know anything about, so I thought the easiest thing to do was to use kterm to add a new user:
Code:
[kterm]# su
[root]# adduser toor
adduser: /etc/passwd: Read-only file system
[root]#
That didn't work.
I just want to be able to login to my Kindle as root. Can somebody shed some light on why my logins are all messed up, or how to properly fix it?
