[MODULE] - Magisk GNU Screen - Magisk

GNU Screen for Android
Here is a module to add the screen command to android shell system wide system-lessly. I sourced the necessary binaries and libs from Termux and adapted to run outside of Termux's sandboxed environment using a wrapper script. From testing it works great on my OG pixel running pie with SElinux enabled.
Useage:
Code:
.┌[09:18 AM] [u0_a224] [/]
└─ $ screen -h
Use: /sbin/.magisk/img/com.geofferey.screen/bin/screen [-opts] [cmd [args]] or: /sbin/.magisk/img/com.geofferey.screen/bin/screen -r [host.tty] Options: -a Force all capabilities into each window's termcap. -A -[r|R] Adapt all windows to the new display width & height. -c file Read configuration file instead of '.screenrc'. -d (-r) Detach the elsewhere running screen (and reattach here). -dmS name Start as daemon: Screen session in detached mode. -D (-r) Detach and logout remote (and reattach here). -D -RR Do whatever is needed to get a screen session. -e xy Change command characters. -f Flow control on, -fn = off, -fa = auto. -h lines Set the size of the scrollback history buffer. -i Interrupt output sooner when flow control is on. -ls [match] or -list Do nothing, just list our SockDir [on possible matches]. -L Turn on output logging.
-Logfile file Set logfile name.
-m ignore $STY variable, do create a new screen session.
-O Choose optimal output rather than exact vt100 emulation.
-p window Preselect the named window if it exists.
-q Quiet startup. Exits with non-zero return code if unsuccessful.
-Q Commands will send the response to the stdout of the querying process.
-r [session] Reattach to a detached screen process.
-R Reattach if possible, otherwise start a new session.
-s shell Shell to execute rather than $SHELL.
-S sockname Name this session <pid>.sockname instead of <pid>.<tty>.<host>.
-t title Set title. (window's name).
-T term Use term as $TERM for windows, rather than "screen".
-U Tell screen to use UTF-8 encoding.
-v Print "Screen version 4.06.02 (GNU) 23-Oct-17".
-wipe [match] Do nothing, just clean up SockDir [on possible matches].
-x Attach to a not detached screen. (Multi display mode).
-X Execute <cmd> as a screen command in the specified session.
┌[09:18 AM] [u0_a224] [/]
└─ $
CHANGELOG:
v1a - Initial Release
v1.1a - Updates to wrapper script & switch to arm bins/libs
v1.2a - Updates to config.sh & screen-setup.sh
v1.2b - Fully system-less, no more mount binding because it's brutal & un-necessary.

TIP: /osh console utilities are accessible on the phone

I noticed earlier today, that it is possible to use all of the webtop's console utilities on the phone's command line by simply changing the PATH.
The PATH you need:
Code:
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/system/sbin:/system/bin:/system/xbin
To make life really easy, make a symlink in /system/xbin to bash, and put the PATH into /osh/root/.bashrc.
Also, there is a full libc on the phone, so that could open up more possibilities on the phone as well.
This is very nice thanks! One thing though, not sure if it's because I'm using a windows command prompt or not, but using bash through adb I get a bunch of funny characters on the screen for example:
# ls /bin/bash
ls /bin/bash
←[1;32m/bin/bash←[0m
# ls -h /bin/bash
ls -h /bin/bash
←[1;32m/bin/bash←[0m
Do you know how to remove those?
Thanks for the tip!
Those are color codes, the console you are using is reporting itself as capable of displaying colors and really isn't!
Check around for a switch to turn off the color codes (or perhaps use another version of ls like busybox ls)

[MOD] Full Linux (Debian) inside WebTop! v0.2.7 [2012/01/18] [11.30 GMT+2:00]

[size=+4]Take back WebTop![/size]​
Use anythings you can imagine! LibreOffice, Java, Firefox 4, ecc...
[size=+2]WHAT THIS MOD DOES:[/size]
Installing WebTopMOD your awm dock will be populated with 3 new icons: leafpad, lxterminal and a penguin.
Leafpad and lxterminal works inside WebTop but clicking on the penguin you get a Debian menu chrooted http://en.wikipedia.org/wiki/Chroot in a Debian enviroment. In xterm you can use synaptic and apt-get to install anything in this new enviroment.
For example I need gimp:
Code:
# apt-get update //refresh packages list from internet
# apt-get install gimp
# gimp //
Clicking another time on the penguin open another xterm IN THE SAME ENVIROMENT so I can start another program
Code:
# oo-writer //openoffice writer
NOTE: Debian disk contain a Debian stable (squeeze) release, some software could be "outdated", if you would live on the edge change stable to unstable in /etc/apt/sources.list IN CHROOT ENVIRONMENT. DO NOT TRY TO CHANGE REPOSITORY IN ORIGINAL WEBTOP ROOT
Look here (http://www.debian.org/releases/) to understand what differ between Debian branches
For example LibreOffice is not yet in stable branch, so you can install OpenOffice or switch repo to testing or unstable
Firefox is renamed Iceweasel and the latest version in unstable is 3.5 and from experimental 4.0.
REMEMBER THAT 0.x VERSION MEAN THAT THIS SOFTWARE CAN BE BUGGED AND I CONSIDER IT IN ALPHA TESTING
[size=+2]PREREQUISITES:[/size]
- A rooted Atrix
- At least 2GB free in internal memory (could be more or less with the customized installation)
- A little bit terminal knowledge and willpower
- Brain
- Liquorice mojito
[size=+2]INSTALLATION:[/size]
[size=+1][1st way - EASY METHOD][/size]
Prerequisite for this method is:
On your phone: CWM installed
0) Download Debian disk - http://droid.makrit.net/WebTopMOD/WebTopMOD-20110707.7z
1) Unpack in your internal or external storage (path should be /sdcard(-ext)/WebTopMOD/linuxdisk)
Please don't use "adb push" it corrupt big files
2) Download easy-signed.zip - http://www.multiupload.com/C5GEIHDEM0, MIRROR
3) Install using CWM, reboot and enter in WebTop!
Uninstaller for version >=0.2.7 http://www.multiupload.com/18H5OHND90, MIRROR
Uninstaller for version <= 0.2.2 http://www.multiupload.com/W37DT6HJ7X
Uninstaller for version 0.2.1 http://www.multiupload.com/TO6W9X7CBU
Uninstaller for version >= 0.2 http://www.multiupload.com/GLKUZA2KP9
[size=+1][2nd way - CUSTOM METHOD][/size]
Temporary deprecated
Code:
Prerequisite for this method is:
On your computer: have a Debian installation or a Debian live cd or download this file ([url]http://www.multiupload.com/403F0OQEDA[/url] -> 2GB disk in 66MB), unpack it and skip to step 8
On your phone: install a "complete" busybox thought any free market apps and be connected to internet with a wireless network.
[b][On your phone][/b]
0) Start WebTop and leave it opened
[b][On your computer][/b]
1) Create a file with the dimensions that fit your needs using dd (I used this command to create the 2GB file: dd bs=1024 count=1 seek=$((1024*1024*2-1)) if=/dev/zero of=debian)
2) Format the new "disk" using ext3 (mkfs.ext3 debian)
3) Create a folder to mount the disk (mkdir temp)
4) Mount the disk (sudo mount -t ext3 -o loop debian temp)
5) Debootstrap! (sudo debootstrap --foreign --arch armel stable temp [url]http://ftp.debian.org/debian[/url])
6) Wait...
7) Unmount disk (sudo umount temp) and remove temp directory (rmdir temp)
8) Copy debian in your internal storage inside a folder called "DEBIAN" (uppercase without quotes)
[b][On your computer if you are using adb (recommended) or on your phone using terminal emulator, connectbot, ecc)][/b]
9) Open a terminal and type:
Get superuser permissions
[code]
# su
edit sudoers
Code:
# vi /etc/sudoers
You should add "%admin ALL=NOPASSWD: ALL" after the line containing "%admin ALL=(ALL) ALL". You can try typing this:
Please note that if you are using a terminal emulator on your phone escape is bad interpreted by Android using a physical keyboard, you have to send the escape key in another way.
Code:
GkyyPjwwwld3wi
NOPASSWD: [with a space]
[Escape]
:wq!
Now we enter in a more complete and privileged bash
Code:
# /usr/bin/sudo -H -u adas bash
Enable AWM to launch anything
Search→Go To… line 1317
Take this line:
use_profile 3
and turn it into:
use_profile 2
Code:
sudo leafpad /etc/tomoyo/domain_policy.conf
Now you can add any launcher to your AWM, look in easy-signed.zip (/usr/share/applications and /home/michele/easy/home/adas/.gconf/apps/avant-window-navigator)
Mount debian disk:
Code:
# cd /sdcard/DEBIAN
# mkdir root
# sudo mount -t ext3 -o loop=/dev/block/loop7 debian root
Debootstrap! (second stage)
Code:
# sudo chroot root /debootstrap/debootstrap --second-stage
Disable X ACL (in WebTop)
Code:
# export DISPLAY=:0
# xhost +
Enter in the new system
Code:
# sudo cp /etc/hosts /sdcard/DEBIAN/root/etc/hosts
# sudo cp /etc/fstab /sdcard/DEBIAN/root/etc/fstab
# sudo cp /etc/resolv.conf /sdcard/DEBIAN/root/etc/resolv.conf
# sudo mount -o bind /proc /sdcard/DEBIAN/root/proc
# sudo mount -o bind /dev /sdcard/DEBIAN/root/dev
# sudo mount -o bind /dev/pts /sdcard/DEBIAN/root/dev/pts
# sudo mount -o bind /dev/shm /sdcard/DEBIAN/root/dev/shm
# sudo mount -o bind /sys /sdcard/DEBIAN/root/sys
# sudo mount -o bind /var/run/dbus/ /sdcard/DEBIAN/root/var/run/dbus/
# sudo chroot /sdcard/DEBIAN/root /bin/bash
Export X display (in chroot)
Code:
# export DISPLAY=:0
Add Debian main repository
Code:
# echo "deb http://ftp.debian.org/debian/ stable main non-free contrib" > /etc/apt/sources.list
Finish debian installation
Code:
# apt-get update ; apt-get install dbus dialog locales
Configure your locale
Code:
# dpkg-reconfigure locales
Install xterm
Code:
# apt-get install xterm
Run xterm!
Code:
# xterm
Now you can install anything simply using "apt-get install PROGRAM_NAME" or installing synaptic
Before unplug HDMI cable you should exit form chroot environment and unmount the chroot:
Code:
# exit
# sudo umount /sdcard/DEBIAN/root/proc
# sudo umount /sdcard/DEBIAN/root/dev
# sudo umount /sdcard/DEBIAN/root/dev/pts
# sudo umount /sdcard/DEBIAN/root/dev/shm
# sudo umount /sdcard/DEBIAN/root/sys
# sudo umount /sdcard/DEBIAN/root/var/run/dbus
# sudo umount /sdcard/DEBIAN/root
[size=+2]USE:[/size] (ONLY FOR CUSTOM METHOD)

[size=+2]NOTE:[/size]
- exporting library you can start a lot of programs without starting chroot (obviously mounting the loop device), for example you can use xterm inside WebTop launching
Code:
# LD_LIBRARY_PATH=.:/sdcard/DEBIAN/root/usr/lib /sdcard/DEBIAN/root/usr/bin/xterm
- you can use sd-card replacing /sdcard/DEBIAN to /sdcard-ext/DEBIAN

However this guide should be applicable to any atrix (att, bell, ecc) with any firmware...
Can i use ubuntu as the debian system on the pc to do the image, secondly how do i make a 4 or even 6 gb image, thirdly is this similar to the chroot modes?

AWESOME!!
You beat me to it!! I just ordered a Atrix and it's enroute to me over here in Japan... I was thinking I would try to build Gentoo on the webtop somehow.
I have experience there doing the whole bootstrapping thing, but then it hit me-- "How will I compile the programs?" since everything gets made from source and not from RPMs or DEBs in that distro.
Now I am totally chomping at the bit for my Atrix to get here; I am going to experiment using it as my ONLY computer at work, and out and about. I tend to use cloud-based apps even when creating content (I'm a teacher/photographer/web developer) and I feel uneasy about taking my loaded-to-the-gills Macbook on crowded Tokyo trains with me everyday.
Now with your find, I can still manage to do some light graphics work at times in GIMP too maybe?

How to install ubuntu on the Droid 4

How to install ubuntu on the Droid 4
Note to mods: this thread is a branch off of this thread
Huge thanks to zacthespack for creating the ubuntu installer app and original boot script and to zeroktal for modifying the script to work on the D4 and helping me get it working on my device.
I decided to take my experience in setting this up and put it into a how-to so that others could enjoy the experience of having ubuntu on the Droid 4. If zackthespac or zeroktal have any problems with me making and putting this guide up, please let me know and I will remove it.
Knowledge Required:
working knowledge of command line
working knowledge of vi
OR the ability to learn how to use both
Tools Required:
A rooted Motorola Droid 4
BusyBox (Android Market)
Terminal Emulator (Android Market)
Android VNC Viewer (Android Market)
Ubuntu Installer App (Android Market)
zeroktal's ubuntud4.zip file (attached to this post and mediafire)
Vi Cheat Sheet (lagmonster.org)
Step by Step:
Install BusyBox, Terminal, and Android VNC Viewer
Install and run Ubunutu Installer App
Follow the on-screen instructions and click next
Download either the Small or Large image to your phone, (use zeroktal's ubuntud4.zip file instead of the boot script provided in the guide) after the image downloads (will take a while because the file is HUGE) click next
For this screen, the instructions differ from the app.
1. With your D4 plugged into your PC in USB Mass Storage, create a directory (folder) called ubuntu in the EXTERNAL sdcard's root*
2. Extract the image you downloaded to that directory
3. Download and extract the attached .sh (ununtud4.zip) to that directory
4. Disconnect your phone from your PC
5. Open terminal and run the following commands:
su [ENTER]
mount -o remount,rw,exec,suid /dev/block/vold/179:1 /mnt/sdcard-ext [ENTER]
cd /mnt/sdcard-ext/ubuntu [ENTER]
sh ubuntud4.sh [ENTER]
960x540 [ENTER]**​If you get an error message: ubuntud4.sh: 45: syntax error: end of file unexpected (expecting "then") see troubleshooting section below.​killall -TERM Xtightvnc [ENTER]
vncserver :1 -geometry 960x540 [ENTER]**​6. Open androidVNC app and enter the following settings:
Nickname: Anything you want
Password: ubuntu
Address: localhost
Port: 5901
Color Format: 24-bit color (4 bpp)
7. Hit connect
8. Hit your menu soft button and then set input mode to touchpad
9. You have ubuntu on your Droid 4!
To "shut down" ubuntu:
press the menu button, select disconnect in VNC
In terminal type this command 3 times (terminal will close itself when you are done):
exit [ENTER]
To "start up" ubuntu again:
Follow steps 5-8 above
Troubleshooting:
If you get the error message: ubuntud4.sh: 45: syntax error: end of file unexpected (expecting "then") you are about to have fun with vi at the command line.
Do the following from inside terminal:
su [ENTER]
cd /mnt/sdcard-ext/ubuntu [ENTER]
vi ubuntud4.sh [ENTER]​If you see ^M or ^ at the end of any line (remember to scroll all the way to the right to see the end of long lines) remove it. once you do that, everything should work just fine. (See the Vi Cheat Sheet above for help with Vi)
Note: Vol Up + E is [ESC] by default in this terminal emulator
Notes:
* It does not have to be on the external SD, but if you put it on the internal SD you will have to modify things as needed-- if you dont know what needs to be changed, just put it on the external SD.
** Screen size can be whatever you want it to be, but 960x540 is the size of the D4 screen.
*** This is a fairly involved process... especially when it comes to editing the .sh file in vi things can get very frustrating and hard, but just take your time and you will get it. As always, doing anything with root access on your phone, especially on the command line has risks. I am not responsible if anything goes wrong with your phone... proceed at your own risk!

** Screen size can be whatever you want it to be, but 960x540 is the size of the D4 screen.
*** This is a fairly involved process... especially when it comes to editing the .sh file in vi things can get very frustrating and hard, but just take your time and you will get it. As always, doing anything with root access on your phone, especially on the command line has risks. I am not responsible if anything goes wrong with your phone... proceed at your own risk!

I actually got it up and running on my internal sdcard partition. Pretty much just have to modify the Mount remount command, and a few lines in the script.
Here's the original command
Code:
mount -o remount,rw,exec,suid /dev/block/vold/179:1 /mnt/sdcard-ext
And the modified one
Code:
mount -o remount,rw,exec,suid /dev/block/vold/179:57 /mnt/sdcard
Only things you have to change are the device location(179:57) and mount location(drop the -ext after sdcard)
Now, after that you also have to modify the script a bit. Just go through it, and anywhere that you see sdcard-ext, drop the -ext off the end.
thanks for putting that up for everybody! like i said, if you know what you are doing its not a hard swap to make.
Is anyone else getting just a gray screen when they remote in? What could be causing this?
i had that same problem at first... did you use zeroktal's ubuntud4.zip file? or did you use the ubuntu.sh file included in the app?
I used the sh file included. I did however fix the problem, when mounting at the start i confused vold with void. I did not get the file system mounted properly. This method does work!! however I am currently trying to get bash on my droid to replace sh as the shell. I've checked the forums but have not found anything yet about someone installing bash on the droid 4. With no way for nandroids I feel i should wait before I kill sh.

Also save the follow lines between ### as remount.sh on your system partition. Then chmod 755 /system/remount.sh. Now you can just run run from a terminal /system/remount.sh and voila it remounts correctly and starts ubuntu(with the above fixes). Im still working on the unmounts.

QUESTION:
After I delete all the ^M and ^ what do i do next? I try to hit the command ":x" to exit and save changes but it just creates another line. Also when I press VOL UP + E to escape nothing happens.

In vi, the command to save and exit is :wq (probably short for write and quit).
remember, read up on the vi quick-reference guide: http://www.lagmonster.org/docs/vi.html
OK I fixed it but now its not letting me connect with androidVNC. All the settings entered is correct but when I try to connect it says:
"VNC connection failed!" localhost/127.0.0.1:5901 - Connection refused"
ok, i've gone thru this a few times (slowly and deliberately) and must be missing something...the directions seem pretty straightforward! here's what i know...
busy/terminal/vnc are all installed
small 2.5gb image is unzipped in /sdcard-ext/ubuntu directory
the attached .sh file from page 1 is in the same directory
i removed all ^M using vi
but when I try sh ubuntud4.sh i get an error...
"mkdir failed for /data/local/mnt/ubun, No such file or directory"
(plus a few other errors)
should the directory be "ubun" or "ubuntu"? am I typing something incorrectly?
copy and paste new script
Copy and paste the new scripts I posted. They will fix your problem. Remember to use the remount script from /system/ the rest will work perfectly if you are root. I'll check back later on your progress.
Ok, well I started from scratch (deleted both .img and .sh files) and it's still not working.
I have all the apps installed (and yes rooted, SU works just fine)
I used Ubuntu Installer app to download the image zip (tried both the large and small img)
I downloaded the .sh file from the first post
The /sdcard-ext/ubuntu/ folder now has two files: "ubuntu.img" and "ubuntud4.sh"
All ^M characters have been removed from .sh file
Still no joy...
Ideas? What am I missing?
In terminal, I can set SU permissions and the mount/cd commands work just fine...it's the last sh command that spits out a bunch of errors about not being able to create/find the directories.
I'm going to format the sdcard and try again...any help is appreciated.
Update: Even after re-formatting the SD and following the steps exactly, no luck!
Did you remember to remount the sdcard with exec and suid permissions?
Andbuntu will work much better than this method. It works on every single phone with modification to the "environmental variables".
http://code.google.com/p/andbuntu/
Follow the directions in the script to make the process much easier than the first post.
instructions:
generate an image with rootstock on an ubuntu computer.
put it on /sdcard/ubuntu/ubuntu.img
run the script on your phone with "sh /path/to/script"
Here is the script. http://andbuntu.googlecode.com/svn/trunk/uboot
Also, run "firstRun" to make things like terminals work properly.
Adamoutler: That didnt work for me. The permissions were incorrect on the mounted partitions.

Dears maybe now I can make double post but I hang on that step from guide from this site.
Phone is after wipe data and I need rescue data from it for that I want to make RAW image to recover data.

Why I get that this parameter is invalid:

And to the end, if that don't work to me, next step also don't work.
Open another Cygwin terminal and type:
Code:
adb forward tcp:5555 tcp:5555
cd /path/to/store/the/backup ---> this is correct, should I creat some folder on HHD and insert here his name?
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0.raw --> that means I should have ftp serwer?
