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)
I'm trying to figure out if my X8 has a Cypress digitizer or not. I type in dmesg | grep cyttsp-i2c and I end up getting a syntax error, to be specific "Syntax error: redirection unexpected write: Broken pipe".
What the hell is wrong with the command I typed in? I've checked numerous times and I'm pretty damn sure I typed in the proper command. And I am rooted.
The exact commands and responses from the moment I start up Terminal Emulator.
Code:
$ export PATH=/data/local/bin:$PATH
$ su
# dmesg | grep cyttsp-i2c
Syntax error: redirection unexpected
write: Broken pipe

Upfronts: I'm using NottachTrix 1.3.1 with the 2.3.6 Webtop. I'm also a programmer and a network administrator, so I might be a little more comfortable poking around in things that might break my phone than other users. Don't do anything you aren't comfortable with! I'm just reporting my findings. Your phone, your comfort level, your business!
I wanted to get my new lapdock to use the cellular network without jumping through any "enable/disable mobile hotspot" hoops. I finally got all the webtop2sd stuff running, including a working lxterminal and synaptic. I was running synaptic as root from a bash shell ("sudo bash" to give me a root shell, other commands as needed). I noticed that synaptic worked without wifi but firefox didn't. I could also ping various websites with no trouble under the root shell, but the adas user could not. adas COULD ping IP addresses, though, so it seemed like there was a firewall in place that was blocking adas from resolving domain names.
As it turns out, there is a firewall in place that is blocking the adas user from resolving domain names.
Webtop seems to be using iptables to restrict access to the default login user. I typed "iptables -L" to view all the iptables-based firewalling that was going on. Sure enough, three entries existed to block network traffic for the user "adas". After an "iptables -S" to get the commands that were used to turn on the filtering, I was able to reverse the process. (Hint: -A adds a rule, -D deletes one)
From here, I could do a lot of things -- create a script to disable iptables on demand, block the commands from running in the first place, dance a happy little jig... I won't embarrass myself by revealing which I actually did, but hopefully there's enough in this post that will help others resolve their problems in a similar manner!
(By the way, every time the phone is docked, it re-blocks network access, apparently using a file called "syslog-restart".)
If you could fix this would be great, I have the same rom and everything and I use my LapDock in my business and it is always a pain to make it connect and most of the times it fails to connect for me.
Cheers
The following presumes a working lxterminal and synaptic (or apt-get). If you haven't run the webtopscripts to fix the broken dependencies, now's a good time to poke that bear*.
(Type the stuff that's in bold -- comments are in italics)
In lxterminal:
sudo apt-get install nano (Command-line text editor)
iptables -S (generates a list of rules that iptables is currently using)
copy any lines in the "-P OUTPUT ACCEPT" section that start with "-A"
create a new file in nano by typing nano fwdisable.sh
at the top of the new document, type #!/bin/bash and press Enter
paste the copied lines into the resulting screen
insert iptables at the start of each line and change "-A" to "-D" (A for add, D for delete)
once the file looks the way you think it should, exit the program with CTRL-X, saving the file when it asks
at the command prompt, type chmod 755 fwdisable.sh
run your new shell script with sudo ./fwdisable.sh
open up a web browser and enjoy!
* Please don't poke any bears. While they may look fluffy, they react poorly to being poked. There's probably a good metaphor about messing around in the internals of your phone in there somewhere, but for the life of me I just can't find it!
Did you guys can edit a ROM that has it all in a matter of WebTop, I can not make it work on my Atrix in any way.
I do not have the device only the HDMI cable.
Trying to save fwdisable.sh nano give me following error
"Error writing fwdisable.sh Read-only file system"
Please advise

Ok the drive was write protected, but now I get

" ./fwdisable.sh: line 3: -D: command not found"
I was not able to get it to work with Nano so I used gedit instead but should not make a difference, right?
Any idea?
maybe someone can create a flashable fix so that its easy for some of us noobs lol

Follow this guide guys, it is ridiculously easy, no flashing needed.
I also added a button to the AWN dock with the command:
sudo ./fwdisable.sh
Which will give you one click disabling of the firewall. It will restart the firewall each time you dock/undock it appears, so just dock it, click the firewall disable button and you are good to go.

Well I'm still getting my error no matter how many time I try it again
man i cant even get webtop2sd to work. as soon as i run it on my phone it force closes. i havent even got it to open longer then super user request yet.
fingers crossed on a cwm flashable lol.
Thanks for this. I was wondering why apt-get update would work but adas couldn't ping out properly over 3g.
Also, thank you for the walk through in editing iptables there. Interesting that they chose to use that over something more proprietary, or well hidden.
I had this problem at first, too -- I think it was busybox-related. There's a busybox updater or two in the Market (I mean, "Play Store") that will bring you up to speed and let you install webtop2sd.
Sorry it's been so long since my last post! It appears that you didn't insert an "iptables " before the "-D". Check to make sure that each line after the "#!/bin/bash" starts with "iptables -D" instead of just "-D" and see if that takes care of the problem. (Also make sure you execute the script with a "sudo" -- iptables won't work properly as a regular user...)

should it be,
iptables -D
or

[email protected]:/$ sudo iptables -S

This is how it looks before editing
It should be "iptables -D". Based on the output from your "iptables -S" command, the file should look like this:
Code:
#/bin/bash
iptables -D OUTPUT -d 127.0.0.1/32 -p tcp -m tcp --dport 8086 -m owner ! --uid-owner adas -j REJECT --reject-with icmp-port-unreachable
iptables -D OUTPUT -d 127.0.0.1/32 -p tcp -m tcp --dport 8085 -m owner ! --uid-owner adas -j REJECT --reject-with icmp-port-unreachable
I also had a third line (that escapes me at the moment -- I'm on a different machine) that further blocked access, but apparently there is a bit of variation in the configuration... At any rate, create the file using whatever text editor you feel most comfortable using, then "chmod 755" the file to make it executable. If you call it "fwdisable.sh", then you should type "chmod 755 fwdisable.sh" in lxterminal and run the file with "sudo ./fwdisable.sh" to disable the firewall.
Good luck! If you want to know more about the workings of this stuff, google "bash scripting guide" and (for a general overview) read the wikipedia page for "iptables". It will help you understand what's up with all these seemingly weird commands...
That worked, but now I get these error messages?

You should be okay with those error messages. I'm not entirely sure WHY it's looking for that file, but it's "normal" output. If you'll remember, it's the same output you got in the "iptables -S" command... Something about accessing iptables causes the system to look for that file. (I just haven't been bothered enough over it to check yet...)
To verify, run "sudo iptables -S" again to see if there is anything left. You should just see three lines:
Code:
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
Anything more than that and you might need to edit your script as you did before. If the output from "iptables -S" looks like the above, though, fire up firefox and give it a whirl!

Excellent! This means you're almost there! As before, copy/paste that line into your shell script, change the "-A" to "iptables -D" and that SHOULD be the end of it.
No, really. This time for sure. Just re-run the script when you're done (ignoring the "fatal" stuff) and you'll be browsing in no time!
If you need to flash ROM even using fastboot for Smartphone or Tablet in which they use Android OS! Then Ubuntu OS is needed!
This is a guide I made for ubuntu users and included a guide for windows users to setup Android SDK which contains ADB.
Android Debug Bridge (ADB) provides a terminal interface on your PC to interact with your device's file system. This can be useful for many things like installing & uninstalling apps, logcat, backup & restore, and hacking your device just to name a few.
ubuntu 12.04 & 12.10 Guide
1. Go here and download android-sdk (not the adt-bundle)....
https://hotfile.com/dl/241406263/5e6a306/android-sdk_r22.0.5-linux.tgz.html
2. Place the downloaded file in your home folder and then extract it and you should get a folder named android-sdk-linux (do not rename it).
3. If you’re on a 64bit machine run these commands in terminal to make sdk compatible with 64bit (if you’re on 32bit machine then skip this step)....
sudo apt-get update
sudo apt-get install ia32-libs-multiarch
4. Run this command in terminal to install jdk if you don’t have it already....
sudo apt-get install openjdk-6-jdk
5. Navigate to the home folder where you extracted android-sdk-linux and open the folder then open the folder named tools
6. Inside the tools folder there will be a file named android... double click it and select run then android sdk manager will open.
7. In the center pane deselect everything... Now only select the following....
Android SDK Tools
Android SDK Platform-tools
Android Support Library
8. Once selections have been made click on install packages and wait till finished.
9. Upon completion of step 8 in terminal run this command....
sudo gedit ~/.bashrc
When the file opens, go to the very bottom and copy/paste the following 3 lines (make sure they’re each on separate lines)....
# Android tools
export PATH=${PATH}:~/android-sdk-linux/tools
export PATH=${PATH}:~/android-sdk-linux/platform-tools
10. Now reboot your computer.
11. Set your phone to usb debugging then plug it to your pc after pc is done booting
12. Open a terminal on your pc and enter....
adb devices
If all went well, you should see your phone’s serial number and you’ll be ready to go.
~~~~~Important~~~~~
You can use steps 5 & 6 to open Android SDK Manager & update your ADB/SDK installation. Only select your installed packages then update.
Also if you only need the fastboot/adbtools:
sudo add-apt-repository -y ppa: phablet-team/tools
Note: delete the space after"-y ppa:" -xda creates smileys like ppa
sudo apt-get update
sudo apt-get install -y phablet-tools

Thanks man! It's also good way!
Followed this guide (thank you for posting) but couldn't connect. Scratched around and found I needed to create a new file in /etc/udev/rules.d with:
Code:
SUBSYSTEM=="usb", ATTR{idVendor}=="<4-char_verndorID>", ATTR{idProduct}=="4-char_productID", MODE="0666", OWNER="username"
Followed by:
Code:
sudo restart udev
Then plugged device in and it worked!

What did you name the new file you created? Or did you add this string to another existing file from the rules.d directory? I'm not sure what I've done wrong, but I get

@atmu5fear, inferring that you're new to Linux (a common background for all), some notes:
Unlike wlth Win-d'oh-s, there is a worldwide development community that's always working toward improvement of every aspect of the system, including echoed messages and documentation. You may have to shake off the tendency to ignore Windudz messages, which are frequently unhelpful. Linux command echoes are much more on-target. Also, look for files such as README in rules.d and read it!
Now before creating a new config file (which may not be necessary on your system), see the top feedback line: "No command 'adb' found." First, see that the adb binary is present and that it has exec permission. (Since it's a small file and functions alone, I prefer to copy it to the folder I'm working from.)
If it then runs but won't connect, read on...
Directory (or "folder") names with a trailing '.d' are special: They configure, control, or provide executables for daemons (programs which run continuously, providing a service).
Within service-config.d folders, if the service steps through the files sequentially (as in this case), then it does so based on each filename. (True except for the special case of rc.d, iIRC, in which order is set by the special program rcorder).
So in this case, for example, since the existing files are named 70-whatever, your newly-created file could be 80-atmu5fears-phone to load after the others.
Should connect.

Thanks @qtoon for the reply. I'm not really new to Ubuntu, albeit, it's been a while. First started using it just prior to the realease of Hardy Heron 8.04 LTS. That being said I am certainly no expert, but am somewhat familiar and comfortable with the command line. I did read the README file before posting, but since I'm not all that familiar with configuration files and the like, I figured maybe I should ask.
As per your suggestion i moved the ADB binary to my home folder, not necessarily my working folder, but to test to see if the adb command would be recognized in terminal.
Code:
mv ~/ADB/android-sdk-linux/platform-tools/adb ~/
Still got same result so I moved it back, then went on to make a new file and add the suggested string
Code:
sudo > /etc/udev/rules.d/80-atmu5fear-adb
sudo gedit /etc/udev/rules.d/80-atmu5fear-adb
After saving and restarting udev I still get the same "adb command not found" error.
I then changed the string to read OWNER"atmu5fear" instead of "username", still nothing
Any more suggestions?
Thanks
atmu5fear
Sorted it out
instead of:
adb devices
i needed to input:
./adb devices
It's listed, and in order to use the adb shell:
./adb shell
once in the shell all adb commands work
I get this error...

Glad you got it running.
Just tried on 14.4 and worked like a charm.
Note: No need to reboot the computer, just reload the bash config with

Hello, can someone help me ? - I m having problems connecting my device with adb (I ve connected several other devices before with no problems).
I ve got an Allwinner A20 tv box, it worked fine for a few months then one day, after being on (but idle) for a few hours, I noticed the screen was blank but the light on the front was blue (indicating it was on, red is standby). It would not respond to the remote control or to anything, so I unplugged it and since then it will not boot and the screen is blank, the red light will light up but that is it. I ve eliminated the remote controller not working, but I cant boot the device.
So I ve tried connecting via ADB (with Ubuntu) but I cant get the device to show up after typing "adb devices".
Using this guide:

The target apk is running the shell such as "cat /proc/cpuinfo" to look up the information.
I tried to hook java.lang.Runtime.exec but just got "sh", not the detail command.
Is there anyway to hook and get the full command?
