Kindle Touch/PW1/PW2 5.0.x - 5.4.4.2 JailBreak. Plus FW 5.x USBNetwork. - Page 95

Ruskie_it · 12-01-2014, 06:47 PM

Finally I installed usbnet.
Install was easy, and I did not modify default config.
At login however I did this (fw 5.4.5.1).
First I tried pw mario. Then fiona. Then fionaxxx with the pass generated by the website. When I used this, ssh shel just hang:

root@acerino:~# ssh root@192.168.15.244

@Ruskie_it: How is the network interface setup on your end?

(And which OpenSSH version is that on your end, [not that it should matter, but there was a smattering of broken downstream versions recently, IIRC] ?).

With a default config, you should be able to enter anything as the password (and I checked that again just this evening w/ the diags build).

What happens if you try to telnet to the device to check the logs? (showlog -f)

I believe it is considered preferable to use ssh keys, see the README_FIRST.txt in the USBNetwork download.

TBH I was not even aware you *could* use password authentication until I reread the docs -- I could swear I read that it was expected to fail.

NiLuJe · 12-01-2014, 07:13 PM

@eschwartz: With OpenSSH, or with SSH-over-WiFi enabled, yes. With the default config (dropbear, no wifi-firewall-hole-punching), nope, the door's wide open

.

EDIT: On the other hand, I have a sinking feeling about the whole locked account thing + dropbear, now that you mention it. Let me double check.

EDIT²: Nope, I'm not dreaming, all's good

.

Code:

ssh -o PubkeyAuthentication=no root@kindle

I don't understand what you would like to know about the network interface setup, instead. I've never used usbnet before, I just used the readme instruction to bind usb0 to the kindle ip. Which works, given that the kindle answers, at first.
I tried with "anything" as a password, too, yet I get the same "permission denied" problem.

@eschwarts: Yes I know ssh keys are preferable, it would have been step 2: first login and ensure I can login "normally", then I would have set keys up. Never got there unfortunately.

Ruskie_it · 12-02-2014, 01:17 AM

Oh, I forgot. Can't remember but I think with telnet it wouldn't even answer. I'm going to retry as soon as I finish uninstalling and reinstalling usbnet.

That sounds a lot like you are talking to yourself.

usb0 ==> bind to the IP address of the PC end of the cable.
Kindle ==> bind to the IP address of the Kindle end of the cable.

I.E: The cable has two ends, and each end has a **different** IP address (it has to, so the packets can tell if they are coming or going, dumb packets

).

So, please post:
(*) What IP address assignment you are using on the Kindle end (defined in the config file on the Kindle).
(*) What IP address assignment you are using on the PC end.

Oh.
Oh!!
Yes, I know what different IP's are for, even though you might not tell so from my dumb display yesterday.

Tell you what, I was mislead by a part of the documentation:

Quote:

I'm using 192.168.15.201 here, because the default settings match the ones used in diags, and some diags scripts expect the host
to be on this specific address.
If you use a custom KINDLE_IP, and/or don't care about diags, you're free to use any (free) address in the correct subnet

.

I don't know why, that led me to think that was referred to kindle ip, and therefore I had to bind usb0 to the kindle ip. Dumb me.
Okay, so, usbnet is now bound to 192.168.15.244, and I bound my pc usb0 to 192.168.15.201.

telnet:

Code:

root@acerino:~# telnet 192.168.15.244
Trying 192.168.15.244...
Connected to 192.168.15.244.

[root@kindle /]# cd

And then it just hung while I was typing. No keypress generated any feedback. I could see from the kual entries that usbnetwork was still enabled and sshd was up, but nothing worked in the telnet session. And by nothing, I mean also ctrl-c or ctrl-d for example.
On a new shell I then tried to ping the kindle (which was correctly responding to ping prior that hang):

Code:

root@acerino:~# ping 192.168.15.244
PING 192.168.15.244 (192.168.15.244) 56(84) bytes of data.
^C
--- 192.168.15.244 ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7054ms

Then, I restarted the kindle and enabled usbnet once again, but yet pings were unsuccessful, and neither telnet or ssh would get any answer.
I rebooted my pc, and ping to the kindle started working again.
So, I went for ssh:

Code:

root@acerino:~# ifconfig usb0 192.168.15.201
root@acerino:~# ping 192.168.15.244

I tought something "broke" my pc, but now I see that when I try ssh also the kindle stops responding...

Ruskie_it · 12-02-2014, 02:34 AM

Again, I unplugged the kindle, disabled usbnet, re-enabled it and replugged the kindle.
ping still not working.
Rebound usb0 to 192.168.15.201, and then ping started working again. So I went with ssh:

Code:

root@acerino:~# ssh root@192.168.15.244

And again, everything hanging.
I opened a new shell, then:

It seems that the network connection fails after a few seconds

Best guess: NetworkManager is evil.

Ok, will try when I get back home. Thank you so much for helping me being able to brick my kindle!

Ruskie_it · 12-02-2014, 04:03 PM

Success!
I couldn't disable network-manager as advised because my linux pc is a headless server and if I stop the daemon my connection to the server fails.
However I managed to configure to bring usb0 up as soon as something is plugged in and then stop managing it, and now connection to the kindle is stable.

Code:

root@acerino:~# nmcli dev status
DEVICE     TYPE              STATE
eth0       802-3-ethernet    connected
root@acerino:~# nmcli dev status
DEVICE     TYPE              STATE
usb0       802-3-ethernet    unmanaged
eth0       802-3-ethernet    connected
root@acerino:~# ssh root@192.168.15.244

Please, say me I am not lost... I had a jailbroken PW2 with 5.4.5.1 version, jailbreak 1.10.N and the corresponding bridge installed. I was sure nothing bad could happen to me because I had also installed the hack to block automatic updates, plus I always keep airplane mode turned on. Until today. But today the worse happened. My son played with the reader and switched wifi on, after some time the reader rebooted and it showed me a nice letter from Amazon happily informing that it was updated at 5.6.1.

From what I read I am lost as I have no way to recover my jailbreak nor to downgrade. Is this really true? No chances to recover?

Please give me some hope, I really hate the original margins and I was the happy user of the fonthack to change them, plus I enjoyed using usbnetwork. Any help would be really appreciated.

Not to panic, not just yet - -
Go to the settings menu and check the device info - see what firmware version is actually running.

I.E: Either of our two update blockers (you don't mention which one you used) should have blocked the update, but not the letter.

I've never used usbnet before, I just used the readme instruction to bind usb0 to the kindle ip. Which works, given that the kindle answers, at first. I tried with "anything" as a password, too, yet I get the same "permission denied" problem. @eschwarts: Yes I know ssh keys are preferable, it would have been step 2: first login and ensure I can login "normally", then I would have set keys up. Never got there unfortunately.

gianpaoloc Member Posts: 10 Karma: 10 Join Date: Dec 2010 Device: kindle	Please, say me I am not lost... I had a jailbroken PW2 with 5.4.5.1 version, jailbreak 1.10.N and the corresponding bridge installed. I was sure nothing bad could happen to me because I had also installed the hack to block automatic updates, plus I always keep airplane mode turned on. Until today. But today the worse happened. My son played with the reader and switched wifi on, after some time the reader rebooted and it showed me a nice letter from Amazon happily informing that it was updated at 5.6.1. From what I read I am lost as I have no way to recover my jailbreak nor to downgrade. Is this really true? No chances to recover? Please give me some hope, I really hate the original margins and I was the happy user of the fonthack to change them, plus I enjoyed using usbnetwork. Any help would be really appreciated.
