Aura H2O Yet another telnet/sshd & misc tools package...

[wings]

After upgrading to kobostuff 1.4, the sftp connecting to my Kobo auro H2O doesnt work. Winscp 5.7 always pops the dialog "no supported authentication methods available server sent: publickey".

It's ok when rollback to 1.3. And my Kobo H2O is on the FW 3.18.0

Can anybody tell me what I can do to solve the problem? Thanks

@wings: Huh. Apparently, interactive/password logins broke somewhere along the way... Thanks for pointing that out, I rarely login without a pubkey.

I don't have time to figure this out right now, but you're not doing anything wrong .

Until I have time to fix it, shared keys work fine, so, there's that, at least .

EDIT: Gah, found the issue. Next build will be fixed, thanks .

EDIT²: Done. Should be fixed in 1.4.N-r12570, thanks for reporting this . (FWIW, it should only have affected builds posted in the last ~2 weeks).

Great, that works fine now! Thank you for the special 'Halloween' verison ;-)

BTW, I know nothing about the public-key based auth, that's why I'm not using shared key auth. Could you please give me the brief tutorial about how to use shared key in winscp+kobostuff/dropbear environment?

I know it will cost your time, so please post just in your convenient time. Thanks.

@wings: I can't remember the state of the docs on that subject, but it's basically the same as on any other OpenSSH/Dropbear system, and there are a large amount of tutorials available on that subject (we might even have some tailored to the Kindle world in the Kindle Dev forum), the only difference is the location of the authorized_keys file (something that should be specified somewhere in the first post).

Granted, on Windows, you may have to jump through a bunch of extra hoops because of reasons (mostly, PuTTy using a different format for key pairs). Once that's taken care of, FileZilla handles PuTTY's ssh-agent (Pageant) transparently (and WinSCP might, too, can't remember).

Spoiler alert: if you have no other use for it, setting up an ssh-agent on Windows may be a tiny bit overkill, and/or more trouble than it's worth.
(Especially in this specific instance where you don't actually have to remember a password, since the ssh server is patched to let anything in).

Hi NiLuJe, I will follow you advice in the spoiler, won't touch the shared key settings in windows.
There's no demand of using the shared key auth, I'm just wondering how it works.

There's my guess:
1. Make a pairs of keys by puttygen
2. Copy the public key to dropbear, though I really has no idea about how to do that.
I guess the public key need to be put in 'usr/local/niluje/usbnet/etc'. However, The public key puttygen made seems an ascii file while the key files in usr/local/niluje/usbnet/etc seem in binary format. And, I only has one public key, but there are three key files, dss/rsa/ecdsa_host_key, in the usr/local/niluje/usbnet/etc!
3. Config the winscp+pageant to work with the private key.

Don't laugh at my guess if it's incorrect.

Hi guys, could you please explain the easiest possible step-by-step way how to connect Kobo H2O via telnet and grab a screenshot? My only command prompt skills were from MS-DOS days

[frostschutz]

Nothing wrong with doing it via telnet, but Kobo also has a builtin screenshot feature, which you might prefer if you're not comfortable with telnet anyhow? You just have to enable it in the Kobo eReader.conf file.

It's fine with me, but I'm pretty sure I've read on other thread that built-in method is not working anymore since some fw update?

It stopped working for a few firmware versions, but it has been fixed for a long time.

[NiLuJe]

No idea if they fixed the broken cropping on the H2O though, I haven't checked in a while since fbgrab pretty much does what I want now .

While playing around with the "windows doesn't detect kobo usb storage" problem, I noticed there is a huge downside to this trick... when using losetup on the Kobo to create loop devices, it's triggered again and again (unless you use loop1 instead of loop0 as a loop device, ...). So mods that don't check if their scripts were already running, suddenly have multiple instances, and other side effects.

Maybe mods should switch to something else after all... or ignore "change" events for loop0.

[NiLuJe]

@frostschutz: Ooh, good point.

Thanks for the heads up, I'll try to look into it. At the very least check that my stuff won't loop (ha!) like crazy if re-run .

Hi NiLuJe,

I have just installed your package, just because I need SSH on my brand new KOBO H2O.

Thank you very much for this development!!!!

I followed your work in old time !
I used your Kindle stuffs on my KNT4 and I very well known your name
There is no dubt this also a quality work from you.

For others step by step how to have ssh on H2O:

Why SSH?

Because this is the one of the simplest way to push documents to your Kobo H2O!


1. download NiLuJe compressed package from this forum #1 post. (kobo-stuff-1.4.N-r13159.tar.xz)
2. Untar kobo-stuff-1.4.N-r13159.tar.xz (i.e.:7zip for windows)
You will find a KoboRoot.tgz in it.
2. Connect Kobo H2O with USB to your PC.
3. Open your Kobo's .kobo directory and copy KoboRoot.tgz to it.
4. Push USB safe remove button on windows, or umount on linux.
5. disconnect USB cable. Wait for update sign.

You done. SSH and other stuffs installed on Kobo

How to start an SSH session?
1. Start Wifi and the Web Browser! on Kobo.
2. Discover your Kobo's IP.:
For example Angry IP scanner is one option. (Free)
3. ssh to Kobo ip:
Linux:
e.g.: ssh root@192.168.178.25 (No password!)
or Putty for windows.
or AndFTP for Android devices! (free)

AndFTP Settings :




How to upload a (i.e.:PDF) document?

Select your file on Android device and upload to Kobo's /mnt/onboard directory.



PDF File is in the right folder. Koreader can show it.

BTW: Anyone know how to refresh Nickel to realise new file arrived?

I hope it is help for others.

Best Regards,
Robert
