Google Voice (call someone data only) on ARM with virtual machine wrapper - General Topics

This might be a little whack, but I am pretty tired that Google hasn't released an ARM version of google voice and video chat that allows dialing out and making telephone calls over a data-only connection.
What I have done so far, is using a micro instance on Amazon AWS, is to set up a virtual machine that has a virtual sound card.
Right now I am using a VLC session to dial out.. I think with a greasemonkey script or something this could be improved.
There are 4 things that need to work.
1: User A (android) --Audio--> [VM]
2: User A (android) <--Audio-- [VM]
3: [VM] --Audio--> User B
4: [VM] <--Audio-- User B
Progress:
1. This is the big one right now, I'm not great with android dev but what I want to do is encode the audio out from the mic to SIP and transfer it to the VM using RDP and then reroute that audio to the virtual microphone. Will utilize some combination of ffmpeg/vlc/arecord/aplay
2: This works (sorta), the VM is generating a VLC stream that I can access on android through RTP
3: This works, Using the virtual sound card (aloop module) "arecord -D hw:0,1,0 -f cd -t raw | aplay -D hw:0,1,0 -f cd &" creates a loop back
4: This works, with the command above, the audio in from User B(4) is heard by User B(3)
Here are my notes (sorry they are a mess). I hope to turn this into a step-by-step walkthrough once I get it going a bit more. It would be great if someone could look it over. I know a ton can be optimized (lower latency, less bandwidth for codecs, etc)

​I wasnt able to get VBOX to emulate the Image so... UPDATE yes i was able to get it working i was having a router issue.So give VBOX a try http://www.virtualbox.org/wiki/Downloads
you can either try to get it to work with VBOX,(goodluck), or dust off one of your old computers and get Ubuntu up.
But you may have to do what i did, i yanked out the family computer from the living room and fit in my literally 4' x 7' office to get this done.

Revised Ubuntu Installation Created By Homefix and RooferDave
This tutorial will show you how to create a Debian Image, Emulate that image using The Qemu Emulator in Ubuntu.And finally setup that image on your EPIC​
I just put this together yesterday, its from my EVO post: http://forum.xda-developers.com/showthread.php?t=881401 .gotta get back to work, the snowstorms over (im from western NY) might be errors will edit and update as time permits
This is made for the epic, but i will try to catch all the changes, i think i got most of em.
Listen up you knuckles, on the evo i can ssh, setup and use samba shares(using hamachi network for connectability), nautilus-shares works, programs dont close, cpu meter works, it truly is like a mini computer in your pocket.
I hope with CyanogenMod i can have the same results because obviosly the epic exceeds the evo because of the keyboard (for this kind of stuff). It sucks to loose half your screen to the input method (with the evo), But i wish the screensize was larger.
For now until there are some kernel changes(hamachi does not work) I have to spend my time playing with that.(Hamachi works in the Evo
However ubuntu seems to run better on the evo
UPDATE cant get Hamachi installed gotta wait for kernel changes -
I guess you can never have the best of both worlds

[Guide] Installing Debian on Android 4.2

Requirements:
An ARMv7 chipset (with VPFv3 if using armhf arch)
Loopback kernel support (if using img file as per this guide, otherwise could use dedicated partition on sdcard).
Rooted device
Busybox
Preparing an image:
On a linux machine setup filesystem for mounting on the android device, below I create a 2GB loopback image.
Code:
# dd if=/dev/zero of=wheezy-armhf.img bs=1M count=0 seek=2048
# mkfs.ext4 -F wheezy-armhf.img
# mount -o loop wheezy-armhf.img /debian
Now we populate the filesystem with the files to complete the debian installation.
Code:
# debootstrap --arch=armhf --variant=minbase --foreign wheezy /debian $DEBIANURL
# umount /debian
Complete installation:
Now on the android device we complete the debian installation.
Code:
# mount -o rw,remount rootfs /
# export LINUXROOT=/linux
# mkdir $LINUXROOT
# busybox mknod /dev/block/loop100 b 7 100
# losetup /dev/block/loop100 /path/to/wheezy-armhf.img
# mount -t ext4 /dev/block/loop100 $LINUXROOT
# busybox chroot $LINUXROOT /debootstrap/debootstrap --second-stage
# mount -t proc none $LINUXROOT/proc
# mount -t sysfs none $LINUXROOT/sys
# mount -o bind /dev $LINUXROOT/dev
# mount -t devpts none $LINUXROOT/dev/pts
Now you can setup any other mounts you want, for example I bind mount my external USB storage etc. Now to login to the debian environment and install ssh server:
Code:
# export TMPDIR=/tmp
# export USER=root
# export HOME=/root
# export SHELL=/bin/bash
# export TERM=linux
# export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin:/usr/local/bin
# export LC_ALL=C
# export LANGUAGE=C
# export LANG=C
# busybox chroot $LINUXROOT /bin/bash
We are now inside debian envrionment and perform some first time setup:
Code:
# passwd root
# groupadd -g 3001 aid_net_bt_admin
# groupadd -g 3002 aid_net_bt
# groupadd -g 3003 aid_inet
# groupadd -g 3004 aid_net_raw
# groupadd -g 3005 aid_net_admin
# groupadd -g 3006 aid_net_bw_stats
# groupadd -g 3007 aid_net_bw_acct
# groupadd -g 3008 aid_net_bt_stack
# echo "deb $DEBIANURL wheezy main" >/etc/apt/sources.list
# apt-get update
# apt-get install openssh-server
# exit
# sync
Now have a SSH service running that allows to login via ssh. Note that if you wish to use networking for other user accounts add them to the aid_inet and aid_net_raw groups. For example for transmission I did:
Code:
# apt-get install transmission-daemon
# usermod -a -G aid_inet,aid_net_raw debian-transmission
# invoke-rc.d transmission-daemon restart

Hi!
First, thanks for your guide, the only one I've seen for Android 4.2
So I have a nexus 4 on Android 4.3 with Paranoid Android custom ROM and rooted with busybox 1.21 JB bionic (included with the ROM). I've done all the steps above until chroot, which gave me an error:
Code:
[email protected]:/ # busybox chroot $LINUXROOT /debootstrap/debootstrap --second-stage
[COLOR="red"]E: No pkgdetails available; either install perl, or build pkgdetails.c from source[/COLOR]
1|[email protected]:/ #
So what now? how do I install Perl for android? Do I have to install microperl from busybox's site?
Please help me, I'm trying to install Debian for 4 days.

I'll look into it, but it sounds like it has not bootstrapped the image correctly.

No you don't need to install Perl. Something as gone wrong with one of the steps. I'll see what I can figure out. Are you using the armhf arch? Cause I could send you a premade image to see if that has any success for you.
Thanks for your help, I've finally found what's the problem (two weeks ago, I've forgotten this thread), but thanks!
(The problem was that the environment variables were not set up properly)
Thanks to these links, I've managed to install Debian 7 on a rooted Android phone. All credit goes to them:

________________
I. On the PC
So first, you have to create the .img file that will contain the OS.
In a GNU/Linux environment (PC) and with the root permissions, type these commands:
Code:
# mkdir debian
# dd if=/dev/zero of=wheezy-armhf.img bs=1M count=0 seek=2048
[COLOR="Red"](NOTE: "of=" will be the name of our .img file and "seek=" the size of the file (MB). Here, we create a file named "wheezy-armhf.img" of 2 GB)[/COLOR]
# mkfs.ext4 -F wheezy-armhf.img
# mount -o loop wheezy-armhf.img /debian
Then we have to fill up the filesystem.
Code:
# debootstrap --foreign --arch=armhf wheezy debian/
# umount debian
Finally, move it to your SD Card. In my case, I moved it on /data/local/
II. On the phone
On your phone, in a terminal emulator and with the root permissions, type the following commands:
Code:
# mount -o rw,remount rootfs /
# export LINUXROOT=/linux
(NOTE: here we'll install Debian on the root of the internal memory, in "/", but we can also install Debian on the SD Card or in /data/loca/linux by changing the path after "LINUXROOT=")
# mkdir $LINUXROOT
# busybox mknod /dev/block/loop100 b 7 100
# losetup /dev/block/loop100 /sdcard/wheezy-armhf.img
# mount -t ext4 /dev/block/loop100 $LINUXROOT
# chroot $LINUXROOT /bin/sh
# export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# /debootstrap/debootstrap --second-stage
The debootstrap's second part should start. Grab a cup of coffee while it's working!
When it's finish, leave the chroot by typing
Code:
# exit
# su
Let's mount the filesystem. We're close!
Code:
# mount -t proc none /proc
# mount -t sysfs none /sys
# mount -o bind /dev /dev
# mount -t devpts none /dev/pts
Now, we have to set the environment variable. Ensure that you have set the correct path of LINUXROOT in case you've chosen another path than /linux.
Code:
# export LINUXROOT=/linux
# export TMPDIR=/tmp
# export USER=root
# export HOME=/root
# export SHELL=/bin/bash
# export TERM=linux
# export LC_ALL=C
# export LANGUAGE=C
# export LANG=C
And finally, chroot.
Code:
# chroot $LINUXROOT /bin/bash
su
Welcome on Debian!
III. DNS and Mirrors
Set a DNS. We'll set the free Google DNS but you can set yours if you want.
Code:
echo -e "domain local\nsearch local\n" >> /etc/resolv.conf
echo -e "# DNS Google\nnameserver 8.8.8.8\nnameserver 8.8.4.4\n" >> /etc/resolv.conf
You can add mirrors to your sources.list if you want. For my case, I'm french so I added french mirrors:
Code:
# echo -e "## Debian Wheezy sources.list\n\n" > /etc/apt/sources.list
# echo -e "## Debian.org FR mirror\ndeb http://ftp.fr.debian.org/debian/ wheezy main contrib non-free\ndeb-src http://ftp.fr.debian.org/debian/ wheezy main contrib non-free\n\n" >> /etc/apt/sources.list
# echo -e "## Debian security updates\ndeb http://security.debian.org/ wheezy/updates main contrib non-free\ndeb-src http://security.debian.org/ wheezy/updates main contrib non-free\n >> /etc/apt/sources.list
IV. VNC
To access your Debian in a graphical environment from your PC or your phone, you have to set up a VNC Server and install a Desktop Environment. Let's install VNC and LXDE.
We'll follow the steps described on the LXDE wiki:
Code:
su
# apt-get update
# apt-get install lxde
# apt-get install tightvncserver
Set up the VNC server by typing the following command, which will ask you to set two passwords (let the second password if you want):
Code:
# vncserver
Kill the session:
Code:
# vncserver -kill :1
Go to /root/.vnc/ and edit the xstartup file: comment out #/etc/X11/xsession and add these two lines:
icewm
lxsession
Click to expand...
Click to collapse
To start a VNC session, type "vncserver -geometry <HEIGHT>x<WIDTH>". For the Nexus 4, we would type "vncserver -geometry 1184x768"
To access your Desktop Environment from your phone, download android-vnc-viewer and launch it.
In the password field, type your password. In the address field, type "127.0.0.1", in port type "5901" and select 24-bit color (4bpp).
V. Script
I've made three scripts to mount, launch and unmount Debian. Whenever you reboot your phone, you'll have to mount Debian, set the environment variables and chroot.

Sorry for my bad english
Thanks for your work and solution. However I did not try it yet, because I'm trying to do it with the following solution. Perhaps I'll do this one next weekend
http://whiteboard.ping.se/Android/Debian
I really like the idea of it.
Just have a look.
P.S: By the way, I'm running Pacman-Rom (4.3) and it seems to work, if you flash googy-Kernel or some other Kernel. CM-Kernel has
some kind of SElinux restriction, which prevents you from changing the debian root password.
Wow, it sounds amazing! I will sure give it a try next week too.
Thanks for the link!

I got stuck in a bootloop after flashing. I'm quite sure, that I did everything correctly...
I think my Pacman-Rom (JB 4.3) is to blame.
Thanks for the guide, was looking for something like this. I tried it first on an SD card formatted to ext4 (wanted a larger than 4GB .img file) but it failed to work. Went back to fat32 and for now kept a 4GB .img and after following you guide, it worked perfectly.

[UBUNTU][DEBIAN]Common Commands used in Linux

Common Commands used in Linux.
Since, Android is based on Linux, there is much possibility that there is a need to use a Linux based OS. For such use, UBUNTU
is favoured, for its easy and more user friendly.
Today, I am going to Post a few commands that are very useful to the newbies to development
I myself am new, and have faced many problems with this, so I am posting a this thread, to help all the noobs/newbies find what they need in a single place
Okay so, lets start with some basic commands, which can be classified as general commands, and each Linux user MUST KNOW ALL OF THEM !!
Code:
sudo
It simply means "Superuser do". It requires password.
Code:
sudo apt-get install APPLICATION_name
This installs the application finding it on the internet, and gives you the suitable output(If the app exists or not).
Code:
sudo apt-get remove APPLICATION_name
It Removes the application
Code:
sudo apt-get update
it updates the repositories
Code:
sudo apt-get upgrade
upgrades your installed application with their latest versions from Ubuntu repositories
Code:
killall APPLICATION_NAME
kills (terminates) an application
Code:
ps -e
displays currently running processes
Code:
kill APPLICATION_PID
kills an application; where APPLICATION_PID.
NOTE: YOU CAN FIND "PID" USING EARLIER CODE.
Code:
wget http://path_to_file.com
downloads a file from the web to current directory
Code:
cd /PATH/TO/DIR
changes current directory to DIR. Use cd to change the current directory into any dir
Code:
cd ..
Like ms-dos, goes up one directory
Code:
dir
OR
Code:
ls
lists directory content
Code:
man COMMAND
Displays manual for command.
eg: man sudo
Code:
cp ORIGINALFILE NEWFILE
Copy a file
Code:
mv SOURCE DESTINATION
Moves a file
NOTE: YOU CAN ALSO RENAME A FILE WITH THIS.
EG: mv old_filename new_filename
Code:
mkdir FOLDERNAME
Make a directory/folder
Miscellaneous: Level 2
Code:
du -sh folder name
This calculates the size of the folder
Code:
ps -aux
This shows all the running processes
Code:
chown -R User:User dir
Change owner of files and directories
Code:
chmod 777 yourScript
This makes a shell script ".sh" extension
Code:
netstat -anltp | grep "LISTEN"
See all open ports on your machine
Code:
sudo apt-get install ufw
sudo ufw allow 80/tcp
sudo ufw allow 22/tcp
sudo ufw allow 443/tcp
sudo ufw allow 21/tcp
sudo ufw enable
Ubuntu provides a uncomplicated firewall (ufw). To install it and only allow SSH, FTP, and webtraffic use the following command.
Network Commands
Code:
ifconfig
Shows the network connections
WILL UPDATE REGULARLY AS MUCH I COULD.
Code:
passwd
Run after installing Linux when you see "[email protected]:~$" to set your root pass word
Code:
adduser
Replace and run to add a new user
Code:
adduser sudo
Replace and run to add that user to sudo
Code:
sudo apt-get purge
Replace and run to purge your system of that package
Code:
apt-cache search
Replace and run to search for new packages to install
Note: "wild cards" eg "*" are acceptable
Code:
find -type f -iname 'some-compressed-file*' -print0 | xargs -0 sudo tar -vxpzf
Replace with at least the "root" directory you want to search through and Replace " some-compressed-file " (leave the single quotes ' ' and the wild card *) and run to find every file under the given directory that has that name and the pipe " | " it out to tar so that'll extract to your current directory
Note: "find" does the finding, the "-type -f" tells find to only look for files, the "-iname" tells find to search parts of file names, the ' ' around "some-compressed-file" keeps the * from doing bad things, the "print0" tells find to "scrub" for spaces and such before outputting a result, the " | " pipes the results of find to xargs, the "-0" is because of "print0" in the find side of the pipe, and "sudo tar - vxpzf" is where tar extracts the findings of find.
Code:
find $HOME -type f -iname '*zip' -print0 | xargs -0 ls
Run to find and list every zip file under the home folder
Say you want to make a file to contain some notes wile in the command line
Code:
sudo cat > $HOME/someNotes.txt <<EOF
# place a command here
echo "hello world, I update aptget"
sudo apt-get update -q
EOF
Try editing the part after $HOME; type it in or write a file that contains the combo of " cat > $HOME/someNotes.txt <<EOF " some text or commands " EOF " and you'll find making custom scripts of varying complexity to be easy.
.......
Hope some of these are also found to be useful for others.
Thanks for starting this here thread.

To delete contents of a large text file ..
Code:
cat /dev/null > NameOfTheFile
Useful variations of ls command :
Show dir content in a list
Code:
ls -l
Show dir content in a list sorted by modification time (newer first)
Code:
ls -lt
Show dir content in a list sorted by modification time (older first)
Code:
ls -lrt
Show subdirectories recursively
Code:
ls -R
If you want to show files starting with . (hidden file), you can add -a option.
More options with command :
Code:
man ls
Useful variations of grep command :
grep is used to print lines matching a pattern.
Find the entry for current user in file /etc/passwd :
Code:
cat /etc/passwd | grep $USER
Find all the entry except current user entry in file /etc/passwd :
Code:
cat /etc/passwd | grep -v $USER
Find all the numbers in file /etc/passwd :
Code:
cat /etc/passwd|grep '[0-9]*'
Add color to grep command :
Code:
cat /etc/passwd | grep --color $USER
(You can add
Code:
alias grep='grep --color=auto'
in ~/.bashrc to always have colored grep)
Useful variations of tar command :
Create archive_name.tar from dirname :
Code:
tar cvf archive_name.tar dirname/
Create archive_name.tar.gz (compressed) from dirname :
Code:
tar zcvf archive_name.tar.gz dirname/
Extract archive_name.tar.gz :
Code:
tar zxvf archive_name.tar.gz
Useful variations of mkdir command :
Create directory and subdirectories if not existing :
Code:
mkdir -p /tmp/a/b/c
(mkdir /tmp/a/b/c will fail if /tmp/a and /tmp/a/b don't exist)
Useful tip :
Use bash variable "!$" to get the value of the last argument of the last command interpreted.
For example :
Code:
mkdir /tmp/test_a
cd !$ (equivalent cd /tmp/test_a)
or,
Code:
mv /tmp/a /tmp/b
ls !$ (equivalent ls /tmp/b)

Rooting the webOS TV

pivotce.com informs that instructions have been published on gaining root access to a webOS TV. This is much harder than on the old phones and tablets. When this was done on legacy webOS, there was a wave of enhancements and tweaks made available to phone users from webOS Internals and other developers.
The instructions can be found on the Russian webOS forums here: webos-forums.ru/topic4650.html (English Translation via Google).
As the thread itself notes, this creates the possibility of fiddling with your TV in a way that may turn it into a large, thin brick and will almost certainly invalidate your warranty. The general user should stay well clear of this.
pivotCE published this for information only and recommend leaving investigations to those who know what they are doing or who can afford to wreck expensive television sets. We will watch to see if anything interesting emerges from this development.

Hello!
I'm from webos-forums.ru. I've root on TV for a while and can help you with translation or testing on LG webOS 1.4.

1. You need to install Developer Mode App and export private ssh-key with CLI (webostv.developer.lge.com/develop/app-test)
2. Convert private ssh-key with puttygen [import key <your private ssh-key>, then save private key]
3. Download exploit (zalil.su/6937580), then connect with TV User: prisoner, [<ip-tv>:9922] + private-key with WinSCP (or other SCP-client), upload to /media/developer on TV and rename it to root.
on linux
Code:
ssh -i <your private ssh-key> [email protected]<ip-tv> -p 9922 "/bin/sh -i"
4.
Code:
chmod +x root
Code:
./root
5. After try install any app from market go to LG App Store and try to install any app.
6. if third stage ok. the insert password 1111 as said.
7.
Code:
busybox chroot /proc/1/root
Code:
[email protected]tTV:/# id
Code:
uid=0(root) gid=0(root)........
I personally use Linux Subsystem on Windows 10 for all of this.
To install .ipk app:
Code:
ApplicationInstallerUtility -c install -p /tmp/<any-name>.ipk -u 0 -l /media/developer -d
Info about your linux kernel and TV firmware:
Code:
luna-send -n 1 -f luna://com.palm.systemservice/osInfo/query '{ "subscribe": false }'
Launch app:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix"}'
All apps ID you can find with
Code:
luna-send -n 1 "palm://com.palm.applicationManager/listLaunchPoints" "{}"
or at a folder /media/cryptofs/apps/usr/palm/applications/<App ID>/appinfo.json
For permanent root access through telnet:
1)
Code:
[email protected]:/# mkdir -p /media/cryptofs/root/etc
2)
Code:
[email protected]:/# cp -r /etc/* /media/cryptofs/root/etc
3)
Code:
[email protected]:/# mount -o bind /media/cryptofs/root/etc /etc
4)
Code:
[email protected]:/# passwd root
Enter any new root password
5)
Code:
cp /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh /tmp/start-devmode.sh
6) Download with WinSCP start-devmode.sh and edit it locally.
You need to add at the beginning
Code:
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
Plus you can add the line to launch any App at start, e.g:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'
And comment Dev Mode online check.
Here it's mine start-devmode.sh. It's for webOS 1.4. It can be different for other webOS versions:
Code:
#!/bin/sh
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
#luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'

Ok, so I get run the root app and first ,second , and third stage all are good. then it says try get root password is 1111. But the terminal keeps freezing after that happens. A couple times my tv rebooted too. I cant figure out what i could have messed up. ANyone with any experience using this method have any legit information?

Try to delete all 'cache' files from exploit at /media/developer. It doesn't wotk twice as far as I concerned
Is there anyway I can root my 1.4.0 and if so what r the benefits of the root? Can I install Android or kodi? What's the point

I tried it stil seems to finish step 3 then says enter 1111. But this is where it freezes up and does not get any further.
Is this still working on 3.6? I'm stuck at try to install any app from market.

Which TV and firmware version?
Is this possible with UJ63 serie?
Hi, would the root access allow somehow to connect other bluetooth devices different than LG? Thanks!
You can do pretty much anything to the system with root, even include support for unsupported devices in form of additional kernel modules.
For example, I've added Samba support so I can mount use my NAS (see my blog at ddscentral dot org for details).
Hey guys is it possible to install android apps into WebOS? I just bought an Lg oled LG 55EG9A7V i want to use Perfect Player IPTV but i cant install it right now...Other then that i dont need anything else..
