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

[NiLuJe]

Finally updated with updated USBNet scripts that work out-of-the-box on the Elipsa, the fancy new updated strace patch, and an FBInk build that works on the Elipsa .

(Along with the usual updates).

When compiling numpy with crossenv, what toolchain have you used? I would like to cross-compile something that uses cython.

[NiLuJe]

@Sky17: Cross Python is not for the faint of heart.

c.f., the insanity that is my build script.

The TC part of it has been made slightly more user-friendly in an offshoot of this script, koxtoolchain.

And as far as Python is concerned, a cross build of Python itself is already a "fun" experience, but a cross build of third-party Python modules with C/C++ code enters Lovecraftian territory...
See the numerous rants about it in the script, as there is no single, sane, official way to do this.
numpy is an even more special snowflake, because its build-system is it in itself a nightmare on top of a nightmare, so I just went with crossenv for that one...

I've installed this package on my Forma and everything seems to work well. For now only to have a standalone SSH server. But I noticed that the Wifi keeps stopping and I have to reconnect again. Is this caused by this package? Or did I just never notice it before?

I also saw that netcat and tcpsvd are running and keeping some ports open. Are these parts of your package? If yes, how can I disable them? Found out how to disable inetd and passwordless ssh but nothing regarding these services. Again: I never did a portscan on my Kobo before installing the package. So I don't know what the default state is.

And sorry if that already got mentioned in the thread, but I couldn't find the information in the opening comment. Just in case I want to uninstall this package, how would I do that?

[NiLuJe]

There's a hidden nickel setting to keep the wifi alive, c.f., NickelMenu for an easy way to toggle it .

I can't vouch for what nickel does in debug mode, but inetd & sshd are the only network services started by this .
There's no real way to tweak that short of editing the startup script (/usr/local/stuff/bin/stuff-daemons.sh).

There's an uninstall package bundled (in the KoboRoot tarball found inside the uninstall folder of the package).

On mobile right now, so I can't quite remember the paths, but it's probably somewhere in /usr/local/stuff or something ;p.

EDIT: There, links & proper paths .

Hi, I'm in the market for an ePaper device for note taking and came across this thread. The "hackability" of the device was one of the factors considered, and it originally came down to the reMarkable tablet and the upcoming PineNote. So I was really glad to see that the Kobo Elipsa is also well supported in this area.

There's a use case that I would like to run by the forum before committing to getting the Elipsa. Assuming that I am able to generate an image of my monthly Google Calendar on demand on an external server, is it possible for me to run a script on the Kobo to periodically download this image (e.g. daily), change the screensaver and refresh the screen (if sleeping)? I'm thinking of using the Kobo as a desk calendar when it's not in use, and having the ability for the calendar to be automatically updated to reflect the new/updated events will be a real plus.

Thanks!

I found something here. Apparently the netcat stuff is a Kobo thing when you enable the developer mode. The device then starts sending logs over Port 5000 and 5001.

The FTP thing I still have to figure out.

Thanks again! You Sir, are really helpful, here and in the other thread. I appreciate that.

[NiLuJe]

Monthly-ish update. Includes Sage/Libra 2 support (probably ;p) for stuff where it matters.

[syvlabs]

Hey NiLuJe, using your KoboStuff and it works great! Just running into 1 problem -- would you know how to compile python libs which requre gcc? In particular when I'm doing a pip install on certain things and python is building the binaries:

 
python -m pip install pycryptodome
...
error: command 'arm-kobo-linux-gnueabihf-gcc' failed: No such file or directory

How can I get gcc in kobo to make this work?

Thanks again!

[NiLuJe]

Not from within a (stock) Kobo, you'll have to go through the pain of cross-compiling a full Python stack.

See the python sections of the x-compile script for at least three different ways to achieve that (because Python). The least painful of which might be to just rely on crossenv (c.f., how numpy is built).

Expect lots of cussing and ranting in the comments.

[matejdro]

Thanks for your work here.

A question though: where do I edit sshd config? Namely, I want to disable PasswordAuthentication.

I tried editing /usr/local/niluje/usbnet/etc/sshd_config, but settings do not appear to stick, even after rebooting the device.

[broodj3ham]

Hi NiLuJe,

first of all, thanks a lot for your work!

I saw in your first post that you also list sqlite3, but when I try to run it, I'm getting "-ash: sqlite3: not found"

Any ideas on how to fix that?

[NiLuJe]

It's part of the Python distribution, not the Core package (for... reasons ;p).

Hi,

I am seeing the following error when using the usbnet-toggle script.

[admin@io root]# usbnet-toggle
* Switching from USBMS to USBNet . . .
insmod: can't insert '/drivers/mx6sll-ntx/usb/gadget/configfs.ko': invalid module format

In dmesg, I see the following error:
configfs: exports duplicate symbol config_group_find_item (owned by kernel)
configfs: exports duplicate symbol config_group_find_item (owned by kernel)

I'm wondering if this is the same issue as alluded to by gerhaher
https://github.com/koreader/koreader/issues/8414

Reverting to build 4.30.18838 seems to correct the issue.

Also, how do I enable logging on my device?

Thanks.

[NiLuJe]

That is definitely the same issue, which I thought I had taken care of (oops ;o).

What do you mean by logging, exactly? (i.e., what kind of logs are you after).

EDIT: Unlike in KOReader, this shouldn't be fatal, though. (i.e., it should still do the right thing in the end).
