Kindle Terminal app (sort of) - Page 3

B_Lizzard · 02-25-2011, 12:12 PM

Um, maybe I'm missing something but how do I invoke the client terminal window? I have the server started, I can see it intercepts my keys when I run it with --verbose but by default, the launchpad.ini file has a system command 'terminal' under the T key, but the actual 'terminal' binary doesn't exist. Was this made for pre-3.1 firmware versions which included a 'terminal' binary or what?

EDIT: Ugh, it worked.

Time to port nethack.

Changes from Luigi last version:

Virtual keys:
Zoom: Change font size (to better fit to window), tree steps
Alt: Toggle alt key. Real alt key is working too, but by this way, you can press more combinations such as ATL+Q etc. (ALT+Q on real kindle keyboard meas 0)
Ctrl: Toggle Ctrl key.
Fn: Toggle virtual FN key. Shows help image. In this way, you can use F1-F2 keys, arrows, TAB, ESC etc.

Keys on side of Kindle:
Up: Toggle FN key (same as virtual button)
Down: Toggle CTRL key (same as virtual button)

Double UTF8 handling (only some characters).

Screenshots:

Attachment 61921

Instalation: just replace ajaxterm.js

Centaurian how did you get the proper caracter set in your last attachment when using mc?

In a Windows console, with export TERM=xterm I have the expected correct output:

But from the Kindle browser + java console, with the same export, I have what follows:

What am I missing?

How about trying 'shellinabox' ?
http://code.google.com/p/shellinabox/
I think it's VT100 implementation is pretty good. The only problem is the keyboard.

Thanks NIXin but I couldn't get the debian binary to launch:

Code:

[root@kindle root]# cd /mnt/us/sinb
[root@kindle sinb]# ls
shellinabox
[root@kindle sinb]# ./shellinabox
./shellinabox: line 1: syntax error: newline unexpected

And I am at loss to cross compile... Also I think that mc (which is ncurses based) expects a vt320 or an xterm terminfo...

NiLuJe · 03-16-2011, 10:00 PM

@PoP: That usually means wrong arch.

Try this (untested, I just didn't have anything better to do

).

You'll probably have to call an SSH client or a patched busybox login applet, unless you know your root password. And disable SSL, it seems sligtly broken, and will call openssl to generate a cert, which will probably take forever on the Kindle HW.

And, if it even works, you probably won't be able to do much, because I assume it expects a full 105 keys keyboard ;o).

Xiaopangzi · 03-16-2011, 10:20 PM

The debian binary works fine for me (after providing the shared libs it depends on) but apart from the keyboard problem (no ctrl-key) it consumes 100% cpu while running...

MC works great in shellinabox (with UTF-8 and full color even, not really needed in kindle though

), but it does expect a full 101 keyboard.
But it shouldn't be too hard to hack the translation of keys to map out the things we need for the Kindle.

Weird you get 100% cpu. I'll try it myself as soon as I have some free time to play with my Kindle.

OK I have the root password... trying... lots of fun playing with openssl... trying... now disabling SSL... trying more with debug:

Code:

[root@kindle shellinabox]# ./shellinaboxd --disable-ssl -b -d
Command line: ./shellinaboxd --disable-ssl -b -d

Adding --user=0 should fix this.

Worked! Many thanks Xiaopangzi.

Of course the Kindle browser/keyboard is not ideal to use mc

Still my question @centaurian in an earlier post remains on how to get the proper character set in is ajaxterm

And ultimately, I would prefer using @lrizzo myts.arm with better compatibility with mc.

First, thank you NiLuJe for x-compiling shellinaboxd for me, worked perfectly.

As a follow up, wanting to be autonomous, I installed the ct-ng toolchain obediently following the instructions of x-compile in the kindle-x-tc archive.

Then compiling "Hello World" (gcc -o hello hello.c) successfully produced a hello binary with no error message.

hello.zip

Alas, when running it on the Kindle I get a "line 1 ... blah blah expected" wrong arch again I Imagine.

If you still don't have anything better to do, can you offer any suggestion to help me debug my installation?

arm-kindle-linux-gnueabi-gcc -o hello hello.c

Use the "file" command (run "file hello" without the quotes) to see if you got an arm, i386 or x86-64 binary.

PoP · 03-30-2011, 01:42 PM

Code:

@Xiaopangzi, that was the piece I was missing!

Perfect now:

Code:

[root@kindle root]# cd /mnt/us
[root@kindle us]# ./hello
Hello World
[root@kindle us]#

You can also set up a toolchain with OpenEmbedded, using "bug" as the MACHINE. You can use "angstrom-2010.x" as the DISTRO, but you'll have to change the configuration files so that it builds with glibc-2.5, which is what the Kindle is using. I compiled SDL this way, and could probably compile anything. I can probably export a toolchain but it's going to be for x86_64 only.

toastofchaos · 08-14-2011, 07:26 AM

Hi, I recently got a Kindle 3/3G SO and I jailbroke it, put launchpad on there, put usbnet on there, and then I tried to get lrizzo's terminal app to work for quite a long time. I've read the launchpad readme and the kiterm readme several times over and I can't quite seem to get it to work.

Now... Do I have to put all of the files that are extracted from kiterm or just the 3 that it says in the readme file? (myts.arm, launchpad.ini, and I believe keydefs.ini). And one other question, trying not to ask too many in one post here, but do I use the search box to enable myts.arm? (which I believe actually got enabled when I tried one time, since it didn't search for what i typed and merely blinked back to home).

But I tried the shift + T command and it didn't bring up a terminal. I'm missing something. Help me out if you can. Thanks!
