[SCRIPT] sudo for Android (requires bash) - Android Software/Hacking General [Developers Only]

There's not a lot to explain here. Just a small novelty script I created on my spare time for fun that essentially does the same thing as sudo on desktop Linux. Each user / app gets its own password which you can set on first run or by typing "sudo passwd"
Usage:
Sudo <command> run single command as root, prompt for password to execute
Sudo passwd - change password for current user
Sudo --usage gives usage info
This is more of a novelty item than anything and isn't particularly practical since you can still just invoke root with su. Passwords are also stored in plain text in /sdcard so it's not exactly secure. But that being said here's the DL link
sudo for Android
Just place the script in /system/bin and chmod it 755.
This script also requires you have bash in /system/xbin, so stock ROMs are unlikely to work without some tinkering.
That being said, enjoy!

Terminal commands

Is there a list somewhere for the commands because i tired to do the "dir" to get a list of files in the folder but it work. (on terminal or adb shell).
* Also what is the best file manager? Is there anything that has a password so that other people cant get into it?
'ls' is the unix command to list contents in a folder
Ok thanks. just been a long time since i messed with Linux shells i guess i should get my books out and start reading again
Android's Linux commands
although he got the wrong command for list files, he raises a good point, the android linux is far from having all commands other linux system have - does anyone have these documented somewhere? what it has and what it doesn't have?

if you are running jf 1.31 then you have busybox installed.. google busybox and you will find out all the terminal commands you can run from your phone terminal or over adb shell.....

ls /system/bin
ls /system/xbin
ls /system/xbin/bb
that should give you a fairly complete listing of the commands available.

I just noticed this myself. I need to remove a symbolic link and recreate it by "unlink" and "rm" dont' seem to work. Is there a busybox command that will do it?
A quick google search brought up this annotated list for those new to these commands:
http://www.busybox.net/downloads/BusyBox.html
JF Thanks for that, I was looking for that folder earlier and could not find it for the life of me. Blame it on drowsiness ...or just plain not wanting to be at work.
That list is only valid for modified Android. Stock Android runs toolbox, which has a much neutered list. Aside from JF's method, you can also look at the tpolbox links in update-script of an official update.zip
Hmmm.. does this mean overclocking is possible? Not that we "REALLY" need it right now but.....
adjtimex [-q] [-o offset] [-f frequency] [-p timeconstant] [-t tick] Read and optionally set system timebase parameters. See adjtimex(2).
Options:
-q Quiet
-o offset Time offset, microseconds
-f frequency Frequency adjust, integer kernel units (65536 is 1ppm)
(positive values make clock run faster)
-t tick Microseconds per tick, usually 10000
-p timeconstant
If you read any manpages on the command you would see that it's for correcting system clock drift.
If you type in "busybox" (without quotes) it will give you the list of commands. Enter "<enter command here> -d" for a description of the command you entered. Hope this helps...
"busybox --help" anybody? i thought the bb we had on our androids was not supposed to be the full busybox?

[HOWTO] Guide to running ADB under Fedora 11 (and equivalent distros)

Ok, I have fedora 11 installed on most of my computers, since i love this distro to death. My big thing was trying to get adb to work. This is my guide to get it to work, for now.
First things first. Navigate to /etc/udev/rules.d as root. Create a rules file called 50-android.rules (touch 50-android.rules). NOTE: You are better off looking at the contents and picking a rules number set other than what is listed. Sometimes udev is picky. For the newbies, so if any rules start with '50', then change the number by one or two, like 51 or 52. Paste this into the file:
Code:
SUBSYSTEM=="usb",ATTRS{idVendor}=="0bb4",SYMLINK+="android_adb",MODE="0666"
Make sure you use ATTRS, not ATTR or SYSFS, since this is a newer updated udev system.
After that, run udevadm control --reload-rules to reload your rules files. Now just run ./adb devices as root to make sure it recognized your HTC dream. I am working on this fix right now so you don't need to be root, keep patient. Now you can adb shell into your device either as root OR normal user, just as long as you start the server as root. This is a permissions problem, and hopefully I can fix this and/or find a fix soon.
I wrote this because i searched high and low through google, and only found a few good parts as far as a fix. Hopefully this helps a few people out there.
Just wondering if this has helped anyone. If not, delete this thread or do whatever with it....
I have adb on my eeepc 900 with f11 I believe this method works too as well. although it says it has been tested with ubuntu, it works pretty well with f11.

Installing The Android SDK
First you will need to download the Android SDK pack .zip archive, once downloaded find a suitable installation location on your machine and extract the zipped files.
Please note: This installation location will be referred to as $SDK_ROOT from now on through this tutorial
Alternatively you can add /tools to your root path which will prevent the need to specify the full path to the tools directory along with enabling you to run Android Debug Bridge (adb) along with other command line tools.
To add /tools:
Linux
1. Edit the ~/.bash_profile or ~/.bashrc files looking for a line that sets the PATH variable.
2. Add the full path location to your $SDK_ROOT/tools location for the PATH variable.
3. If no PATH line exists you can add the line by typing the following:
4. export PATH=${PATH}:<path to your $SDK_ROOT/tools>

It helped me, since the creation of the file my OpenSuSE 11.0 recognizes the phone perfectly
Thanks a lot for your hint.
thanks it helped me. ill be looking forward to getting it to work without root
just use sudo instead
Just a heads up for user's using Ubuntu 9.10, this isn't needed. I connected my G1 to it and ran ADB with no adjustments to udev or anything else.
Pretty much it works out of the box.
Here is my version
download the .tgz file from googlecode
http://developer.android.com/sdk/index.html
sudo tar -xzvf android-sdk_r3-linux.tgz
Click to expand...
Click to collapse
Code:
sudo gedit ~/.bash_profile
heres my bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH=$PATH:/android-sdk-linux/tools
Click to expand...
Click to collapse
logout
login
connect android g1 device via usb to pc
open a terminal
Code:
adb devices
if you cant get a device try it with superuser.
Don't you think that this is all just a little bit excessive?
To make it work in F11, just do this;
Download SDK, extract.
To use, type:
/path/to/sdk/tools/adb
Another option is to edit the /etc/profile and add
PATH=$PATH:/<Path to android-sdk>/tools
This option will allow any user to use the adb tools when logged in or if you
su -
into another user
I wrote a short guide as well for Windows and Ubuntu. Might help others.
Unfortunately, as anyone with a passing acquaintence with ADB knows, the scrolling issue can be a killer. I swear the other day I pressed "up" twice and it composed "rm /sdcard/rootfs.img /sdcard/system.ext2" and executed it. We run Android on our SD's btw.. Was not cool. Instead, I use ADB via telnet and it works beautifully. Here's how:
Code:
adb shell telnetd &
adb forward tcp:9999 tcp:23
Now type this: "telnet localhost 9999"
Enter "root" and hit enter
Finally update PATH: "export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/system/sbin:/system/bin:/system/xbin:/system/xbin/bb:/data/local/bin"
Okay, so 4 lines to enter and you have a "regular, sane" shell connection to the phone and you can actually scroll through history and text without it jumbling the text and executing random code. Enjoy.

WHY would you want to make it *MORE COMPLICATED*??
There is NO NEED for root.
/path/to/adb ...
THATS ALL.
This is kind of funny... i wrote this because i had trouble with it, so i am just sharing my fix...
In case this is interesting to someone:
The fix mentioned in the first post has to be applied to open SuSE x86 and x64 edition to make the G1 work. The external device works without it, but not the adb device.
Thanks again!
Just wanted to come and post that this does work with OpenSUSE 11.2 x86. Did this hoping to get adb to work with my LG Ally and it does. Thanks!
(Still) works for me on 64bit SUSE 11.4.
Before adding this file, I could not access my device with adb, received permissions errors.
Added this file, and I can shell into my device.
Permissions on adb itself was not the problem, it was access to the device when udev found it.

GOOGLE TV & Better Terminal Emulator V4.0.3

First of all I would like to thank my intuitions on this discovery! the SONY Google TV can be rooted, well, at least the /system partition can be changed to read/write. I have not actually executed the command to do so, but I do know the necessary path to the Google TV's /system partition. I recently discovered that the the Google TV uses Better terminal Emulator pro V4.0.3, and I was looking around on the magicandroidapps.com WIKI and noticed that there was an application called TV Terminal Emulator Pro, but I think that was a throw-off. Better Terminal Emulator Pro version 4 works perfectly when trying to access system level permissions on SONY's (notice I said SONY) Google TV. Here are the facts. Hopefully someone can try the usual remount command and switch the system to read/write
1.install Better Terminal Emulator Pro (version 4.0.3 ONLY!) no other version will work
Hit the menu button in your SONY Google TV remote once the terminal has opened and in the default shell setting, choose the Almquist shell as the default!
2.type this command in the terminal
\ $/system/bin/ash
This will give you permission to execute all /system/bin commands(ash=advanced shell)
you will now have a prompt like this one below
\w \ $
3.you can now type this command to see all files in /system/bin directory:
\w \ $ls /system/bin
4. type this command:
\w \ $/system/bin/mount
NOTE: This command will give you a list of all partitions within the TV's file system!
NOTE:The system partition will be in the list of mounts called /dev/block/sda5. It is the only one of two mounts that is in read only mode.
NOTE: This directory is a ext3 file system, and this should be added in the remount command in terminal. Plaese give me some feedback on this matter because I know you GTV fans have been waiting on something like this!!
GOOGLE TV & Better Terminal Emulator Pro V.4.0.3 [UPDATE]
So have figured out how to issue the command to remount the system partition to rw, but it appers that I am not in root? For those who do not know the command, here it is:
\w \$ mount -o remount,rw -t ext3 /dev/block/sda5 /system
mount: permission denied (are you root?)
This is no big deal, this just means that we are getting closer to seeing just what this giant tablet can go. This also means that the command is corrects as well, for one to get an output like the one above., I will try to use another shell and see what commands will have to be executed and get back with all you GTV users.
NOTE: This is post is related to the (SONY Internet TV) and NOT the LOGITECH Revue
ALSO: Those of you who are trying to use ADB to control the television, The \$ adb root command cannot be executed in a production build of GOOGLE TV, which led me to go with Better terminal Emulator Pro.
GOOGLE TV & Better Terminal Emulator Pro V4.0.3 [UPDATE]
Hay guys, I was playing around some more with the terminal and I see that there ARE busybox commands present in the application.
I think the trick to rooting the SONY NSX32GT1 would be the CHMOD command. Entering this command while in the BASH shell when the emulator starts will give you the options for executing the command properly. if smeone can help me out with this command to change the permissions of the /system file system, that would be great. The CHOWN command may be of some use as well. I am almost 100 percent sure that if we change the permissions of the filesystem with one of these commands, we will be on our way to getting proper root access to out TVs!
If you are familiar with linux commands, please post a reply with the proper execution, and I will, in return, provide some very exclusive information about the television!
Here are some pics of the terminal up and running with busybox v1.16.2 built in.
i believe u may be speaking of commands like chmod -R 777 /system to give read write and execute permissions to user group owner .or chown root:root but to do any of that u must be root (the owner of most system files) or owner of said files in order to change owner group permissions and more. those commands come after a su or sudo in full bash. so u would still have to remount as rw. but the fact u got busybox installed is nice perhaps we can start looking at other root options if the busybox commands can be found during zerg or other overflow

Terminal and SSH access

As a new Android user but experienced in Linux I wanted to explore the command shell. I've wanted to change passwords and have use the usual commands I would normally expect to be available.
I'd like to share my experience for any other new user and open the discussion for for additions and corrections. What I say here works on a Galaxy Mini S5570 but should be pretty generic. This really does need the phone to be rooted or much will be inaccessible.
Comparing 3 methods Terminal Emulator, DigiSSHD which is run from DigiControl and SSHDroid.
There is no concept of a root password as access is granted via superuser app. When you connect your id is set from the id of the app you are using to connect.
The simplest connection is via Terminal Emulator. It requires no network connection and gives direct access to the phone. The first thing is that you have no home directory so you are dumped into / the top directory. There is no .bash_profile, .bashrc or .profile so it's customisation is not obvious.
I tested SSHDroid and DigiSSHD using wi-fi. My ssh client was the excellent Putty on Windows7.
As default SSHDroid uses port 22 while DigiSSHD uses port 2222.
For a rooted phone SSHDroid has user "root" with password "admin". This is not your device's root password. You can think of it as an access password for SSHDroid. This access password can be changed in the options for SSHDroid. It is a good idea to do so stop others getting in just as you have done.
You arrive in a home directory data/data/berserker.android.apps.sshdroid/home and inside there you will find a .profile file so you can do some customisations there. The good news is that all the usual linux functions are available in ~/bin via the PATH variable it gives you and its own busybox.
Neither Terminal Emulator nor DigiSSHD give you these functions but this is a good way to do it.
Terminal Emulator by default gives you a PATH which includes /data/local/bin. This is set by Initial Command in the Preferences but I'm taking it as it is.
There was no directory /data/local/bin. This is good because we can create it and put our own stuff in there wihout having inconsistent clashes. Create it with the correct permissions. Copy the permissions of another directory in the path in my case I used /system/bin. To check the permissions:
cd /system
ls -l
The permissions were for bin are drwxr-xr-x with Owner/Group of root and Shell. So create the new directory.
cd /data/local
mkdir bin
chmod 755 bin
chown root.Shell bin
Now you can start creating your utilities. Before you do check that each is not already available by trying to run it. It might already be provided by Toolbox. To see what busybox can do type
busybox --help
To get your utility, assuming it is available in busybox create a symlink to busybox with the name of the utility. As an example this is how to create 'more' and 'less' and the standard 'vi'
cd /data/local/bin
ln -s /system/xbin/busybox more
ln -s /system/xbin/busybox/less
ln -s /system/xbin/busybox/vi
You can carry on activating your favourite utilities. Remember to check if it already there first and NEVER forget you are doing all this as root so take care...
Why do it this way and not use the functions provided by SSHDroid? Well as an ordinary user you may not have access and if you decide to uninstall SSHDroid you would probably lose it.
Now for DigiSSHD. The default user is android with a password of 123. I have not found how to change this yet so comments welcome. Your home directory will be something like /mnt/sdcard/Android/data/org.digimead.digi.ctrl/files/var/1d7a337e-7cf8-4b28-8039-baa894f7185f
There is a .profile file in your home directory that you can edit and add the line
export PATH=/data/local/bin:$PATH
This will give you access to the same utilities (so same versions) as you have with Terminal Emulator.
That's it. The rest is up to you. Which utilities you chose and which command line app suits you. I doubt that all the busybox functions will work on an Android system because it is not an ordinary Linux.
Which is better, SSHDroid or DigiSSHD? I don't know. I'll leave that for others to comment.
Are you the admin on this other site? Terminal and SSH Access Just curious as this is exact copy/paste post from that post with no links or attributions.

[TUTORIAL] Resetting a Parental Lock without Factory Resetting (no pre-root required)

So I just spent a few hours digging into this and thought someone might need it sometime down the line.
My wife's job uses a Kindle Fire HD 10 and they have a parental lock on it. Today they needed to change a Wi-Fi setting and couldn't remember the lock password.
The following tutorial will use adb to temporarily root your Fire, update the database to corrupt the lock, and create a new Parental Lock.
What you'll need:
ADB
mtk-su (Download from the first post here, don't worry about using their tutorial since I'll reiterate it here)
1. After you download mtk-su, push it to your device
Code:
adb push path/to/mtk-su /data/local/tmp/
2. Open an adb shell and cd to the data/local/tmp folder
Code:
adb shell
cd /data/local/tmp
3. Write executable permissions to the script
Code:
chmod 755 mtk-su
4. With the screen on, run the script:
Code:
./mtk-su -v
5. You should now be at a root shell (you can tell by the # instead of the $ symbol). Read the mtk-su thread for debugging if you don't get a root shell.
6. Get to your databases folder:
Code:
# cd /data/data/com.android.providers.settings/databases
7. Send some commands to your settings.db to overwrite those parental password values:
Code:
sqlite3 settings.db "insert into secure values(NULL,'parental_password_exist', '0');"
sqlite3 settings.db "insert into secure values(NULL,'parental_control', '0');"
sqlite3 settings.db "insert into secure values(NULL,'com.amazon.parentalcontrols.changed', '0');"
8. Delete the original password salt and key files via:
Code:
rm ./data/securedStorageLocation/com.amazon.parentalcontrols/files/*
9. Congrats, your parental controls are now corrupted! Your WiFi, among other things probably, will not work! Head over to your Settings and click on Parental Controls. Turn them on and create a new password. Now everything will work again.
