Kindle Touch/PW1/PW2 5.0.x - 5.4.4.2 JailBreak. Plus FW 5.x USBNetwork.

Impossible SSH by Wifi. I can't get root password. I tested:
- Accessing by usb with framework/mario and changing root password. After enabling SSH by wifi, no password works.
- passwords sugested for my serial in several places: fionaXXX, mario...
- exporting passwd and shadow files with John's unshadow utility. When tried extract it, error: "No password hashes loaded". Tried described solutions and nothig...
Definitely, when I enable SSH by wifi I have to restore because of there is no way to access, not even by usb.
Can you suggest me some other way to get the correct root password?

On what device?
On what firmware version?

If on a Paperwhite, shown in your info block, there isn't one.
Which makes it hard to find and should explain the error message: "no hashes found".

@mg10: What knc1 said.

Either set up shared keys auth (best), or set your own root password over usb, with ssh over wifi disabled (meh).

Also, read the docs, of course you can toggle the status without shell access. (;un).

I forgot it: PW1 and firmware 5.4.4.2

I did not test shared keys but changed root password by usb and after enabling ssh over wifi the connection is not possible any more, not even over usb because new password doesn't work. That's the reason because I have to restore to defaults.
I have a doubt: once enabled ssh over wifi, the ip used is the assigned to wlan0 interface or the one configured in usbnet/etc/config file?

[NiLuJe]

@mg10: You probably failed your password switch, or missed something (hint: read the doc).

Switch SSH over WiFi off in KUAL, cycle USBNet status to relaunch the SSHD, and do it properly this time .

Nope, over WiFi, IP handling is obviously done by your router. You'll still be able to connect over USB w/ the IP setup from usbnet/config, but you'll need a valid auth method (until ssh over wifi is disabled, and usbnet state cycled) over there too.

The 'swiss cheese' passwordless login is only enabled with: dropbear as the sshd, ssh over wifi disabled (i.e., the default settings). Any other combo requires a valid auth method, and since FW 5.3, the root account is locked, so there's no 'default' password.

And I reiterate that you don't need to reset to factory defaults, you can toggle USBNet from the searchbar no matter your settings. (read the docs).

In case you missed the general idea: read the docs.

Thanks NiLuje for your reply.
I haven't KUAL, so I need ssh acces to switch ssh over wifi off (editing config file).
The problem is that after enabling ssh over wifi in config file and restarting, if I want to return to usb connection I have to enter ; un in search bar and connection is restablished but I just can ping or ssh because password (old and new) stop working.
I must doing something badly but what I don't understand is why behavior of password for usb changes after enabling ssh over wifi.

[NiLuJe]

@mg10:

;un toggles between usbnet and usbms, no matter the settings. Go back to USBMS, reset to a sane config, and voilà.

The behavior changes as soon as you enable ssh over wifi in order to close the gaping security hole of leaving a device on a WiFi network open to the four winds (passwordless root access + wifi == bad).

HOW did you change the root password? (steps used, results seen)
How did you test that the new root password was working before trying to use it over Wifi?

Also keep in mind, that telnet does not require a password if you get really stuck.

[NiLuJe]

Unless you enable ssh over wifi *only*, in which case you don't get telnet, but on the other hand you're left in USBMS anyway, so you're not stuck.

(The actual KUAL button for that setting is way clearer than the name of the variable ).

My steps:
Connect by usb with default ip in config file with user root and pass blank
mntroot rw
Edit config file and change SSH OVER WIFI to true
passwd command to change it and test it by usb
Restart device and enter ;un in search
At this moment I have ssh connectivity by wifi. Ssh asks for user and password but nothing
If I plug usb, same behavior, connectivity but no password works.

I didn't test telnet. It's a possible solution to avoid restore and be abble to change config file again.

@mg10: Telnet, or just switch to USBMS.

Ok, thanks very much for your help

Finally I got it
Would be doing something wrong. Changed root password by telnet, configure ssh over wifi and everything ok. Now it works perfectly. Thanks, NiLuJe and knc1 for your help and your patience.

Hi all,

I have a brand new PW2 3g, 9060 shipped to Italy. Update Your Kindle keeps staying grayed out. Am I missing something? I'm currently on 5.4.3.2 and I'm keeping it on airport mode to prevent forced OTA updates.

Thanks in advance!
