WARNING: THIS IS NOT FOR THE FAINT OF HEART
UPDATE: My goal was to create a version of BackTrack 5 for ARM that was easy to use and install. As of this time, that IS NOT the case! The versions posted here are **probably not** going to work straight out of the box. If you know what you are doing in a Linux environment, you'll probably be able to get it working.

Because of this, the project is currently completely unsupported. You are free to dive in, but you are doing so with no support for me, and I'm not liable for any damage that might be done to your device's ROM.

I encourage you to pass this up unless you know what you are getting yourself into!



If you were referred here from the XDA-Developers.com article...
Hi there! Let's get one thing on the record here... this is *not* a native client! This is the chroot + VNC method that we'd been using to get Ubuntu running with Android for a while. The article makes it sound like that's the case, but sadly it's not. However, with the chroot + VNC method we can really run BackTrack 5 on an Android device, and it really does work. This takes some technical skills, and isn't for the non-Linux experienced user.

Requires a rooted device!

BackTrack 5 installation guides are making their way around this forum. I've tried to synthesize it all, but I've also added my own touches to help with usability and features, along with a workaround for the "ioctl LOOP_SET_FD failed" error message some people have been getting.

In theory this build is nearly universal, so if you have an Android device it should work. I've put it all in one zip file that you can download directly from my website, no hassles or wait timers.

If you are interested have a look, feel free to re-post. Credit goes to the BackTrack team and xda member anantshri (he's got skills, give him props guys), who built the base image file.

If you don't know what BackTrack is, you probably don't want it :)

BackTrack is an operating system based on Ubuntu Linux that is used for security testing (aka hacking) and digital forensics. I'm a master's degree student in computer security, so I love this OS... it can do awesome things. Turn on your Wi-Fi and you can do advanced network scans and tests right from your phone, no laptop required. For me this is hella-useful.

But besides just being an OS for hacking ****, it's also fully Ubuntu-based, so you can run it like a desktop, including running Firefox and other Linux applications.

Well guys my server had hardware failure (lol, my luck), so here's the website's content:

The Download

This installation of BackTrack 5 is available as a compressed file that will need to be extracted. I recommend downloading this using Chrome or Firefox. Internet Explorer often doesn’t play well with large HTTP downloads.

The root account’s password and the VNC server password are both set to ‘root’ by default!

The Description

If you want to run BackTrack 5 on your Android-powered device, read on, you’re in the right place! So the big news is that BackTrack 5 runs on Android phones. We’ve been able to run Ubuntu on these devices for quite some time too, but admittedly BackTrack on a smartphone is just awesome.

Anyway, files for using BackTrack 5 on an Android phone have been running around the internet, but sadly it’s kind of a mish-mash of links saying, “go download this, then get this, to then this, blah blah blah”. Too confusing for my simple brain, so I’ve rounded it all up and posted it in one place… right here. The version posted here has everything you should need to run BackTrack 5 on your Android device. I’ve also added a lot of goodies to help with the user experience that the other offerings don’t include:
  • Works around the ioctl LOOP_SET_FD failed error that many people have been receiving on Galaxy S devices (and others)
  • Asks the user if they want a VNC session upon start-up
  • Starts the SSH service automatically and displays device IP on start-up
  • Enables the Ubuntu repositories to Aptitude, so you can do package installation
  • Adds vim. Really, what distribution doesn’t come with vim by default? Seriously…
  • Sets the screen resolution to 800×480 default (should be compatible with most smartphone devices)

SU
This requires root!
You must be able to "su" at terminal. This ability is usually provided by software for rooting your phone. To see if you have rooted your phone correctly and it's working, go to your terminal emulator and type "su" <enter>. If it is working, you'll probably get a prompt asking you if you want to allow your terminal emulator root access. Hit accept/yes. Now you'll be back in your terminal emulator. Type "whoami" <enter>. If it responds with "root" or "uid 0", then you are properly rooted.

Busybox
This requires Busybox!
I am no longer providing an installer for Busybox because of issues getting it to work universally, so instead YOU need to go get a working build and install it (I believe "Busybox Installer" will work, but not tested). If you want to know if you have Busybox and it's working, go to your terminal emulator and type "su" <enter>, then "busybox ls" <enter>. If you get a printout of all the files in your current directory, then your Busybox will likely work with BackTrack 5 just fine. If you get an error, "busybox: not found", that means you either do not have Busybox, or it is not properly installed.

WARNING FOR CyanogenMod USERS
Before doing ANYTHING, please test for ext2 support by running (as root, at terminal) --> "modprobe ext2" <enter>

If this fails probably your device lacks ext2 support and the whole thing will screw up if you try to run it! Support for ext2 in CM is being worked on.


The Installation Guide

  • Enable Wi-Fi and connect to a Wi-Fi access point (* not required, but BT5 cannot use your data plan for internet access)
  • Download the zip file, extract anywhere
  • After extraction you’ll have one folder “bt5″; copy this folder to the root of your phone’s SD Card
  • Put card back in phone and/or unplug from USB
  • In a terminal emulator, type “su” <enter>, “cd /sdcard/bt5″ <enter>
  • Now you are ready to rock and roll, so issue “sh bt” <enter> (in the future to start BT5 skip the line above and come straight to this command)
  • If all is well you’ll now be running BackTrack 5 on your Android device; you can SSH to it via Wi-Fi (password ‘root’), or access it from VNC if you said “Yes” to the prompt asking if you wanted a VNC session
  • To get a GUI for BackTrack on your smartphone’s screen, download a VNC viewer from the market (many are free), then connect to host “127.0.0.1″, port “5901″, password “root”

Enjoy, boys and girls.

Hrm yet another small error in one of the scripts. So sorry :S (this script is from the BT5 team though, so I take no fault in it not working, lol).

Open "installbusybox" in a text editor and replace the text "cat /sdcard/busybox" with "cat /sdcard/bt5/busybox" it should work. I'll fix it and put it up online once I'm home from work today.

    Re: Installing bt5 on android

    REQUIREMENTS:
    1.your phone must be rooted
    2.apps to be installed on your phone androidvnc,terminal emulator.get these from market

    TUTORIAL:
    on pc:

    After downloading arm version of backtack5 extract it on ur pc and must have 5 files on it .
    1.bt
    2.bt5.img
    3.fsrw
    4.mountonly
    5.unionfs
    step1:
    open the bt file in wordpad,delete all its contents and paste the following code and save it

    ##########################################
    perm=$(id|cut -b 5)
    if [ "$perm" != "0" ];then echo "This script requires root! Type: su"; exit; fi
    mount -o remount,rw /dev/block/mmcblk0p5 /system
    export kit=/sdcard/bt5
    export bin=/system/bin
    export mnt=/data/local/mnt
    export sdcard=/mnt/sdcard
    export extsd=/mnt/extSdCard
    export USER=root
    if [ ! -d "$mnt" ]; then
    mkdir $mnt
    fi
    export PATH=$bin:/sbin:/usr/bin:/usr/local/bin:/usr/sbin:/bin:/usr/local/sbin:/usr/games:$PATH
    export TERM=linux
    export HOME=/root
    if [ -b /dev/block/loop255 ]; then
    echo "Loop device exists"
    else
    busybox mknod /dev/block/loop255 b 7 255
    fi
    #mount -o loop,noatime -t ext2 $kit/bt5.img $mnt
    losetup /dev/block/loop255 $kit/bt5.img
    mount -t ext2 /dev/block/loop255 $mnt
    mount -t devpts devpts $mnt/dev/pts
    mount -t proc proc $mnt/proc
    mount -t sysfs sysfs $mnt/sys
    mount -o bind /mnt/sdcard $sdcard
    mount -o bind /mnt/extSdCard $extsd

    if [ ! -d "/data/local/mnt/sdcard" ]; then
    mkdir /data/local/mnt/sdcard
    fi
    busybox mount -o bind /sdcard /data/local/mnt/sdcard
    busybox sysctl -w net.ipv4.ip_forward=1
    echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
    echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
    echo "127.0.0.1 localhost bt5" > $mnt/etc/hosts
    echo "Back Track is configured with SSH and VNC servers that can be accessed from the IP:"
    ifconfig wlan0
    echo " "
    busybox chroot $mnt /bin/bash

    echo "Shutting down BackTrack ARM"
    umount $sdcard
    umount $extsd
    umount $mnt/dev/pts
    umount $mnt/proc
    umount $mnt/sys
    umount $mnt
    losetup -d /dev/block/loop255

    step 2:
    create a folder named bt5 and move all the 5 files to that folder
    connect phone's sdcard to the pc and copy bt5 folder to the root of your sdcard

    ON PHONE:

    STEP3:
    open terminal emulator
    code:
    cd sdcard/bt5 [you must be on bt5 folder]
    su [for granting super user access]
    sh bt

    then it asks for [do you want to start a vnc server]? type y
    then terminal window is like this

    [email protected]:~#
    then type startvnc and press enter
    [email protected]:~# startvnc
    minimize the terminal emulator app

    STEP 4:
    open androidvnc app

    in the connection option select new

    in the nickname option type root

    in the password option type root

    in the address option type 127.0.0.1

    in the port option type 5901

    in the color format option select 24-bit color

    and leave the others
    STEP 5:

    click on the connect button.:)
    BACKTRACK5 WILL SURELY RUN ON YOUR ANDROID PHONE
