Running Android Applications on Ubuntu

noreply@blogger.com (David Windarto) — Wed, 29 Dec 2010 20:30:50 PST

Step 1 - Installing the requirements

Until the download is over, make sure that you have Java installed and the 32-bit libraries (for the x86_64 users ONLY). If you don't have Java (or the 32-bit libraries), go to System -> Administration -> Synaptic Package Manager...

...search for openjdk and double-click on the openjdk-6-jre entry...

...then, search for ia32-libs (ONLY if you are on a x86_64 machine), and double-click on the ia32-libs entry...

Now, click the "Apply" button to install the packages. Wait for the packages to be installed and close Synaptic when the process is finished.

Step 2 - Android Setup

When the Android SDK download is over, right-click on the file and choose the "Extract Here..." option...

Enter the extracted folder, then enter the tools folder and double click the android file. Click on the "Run" button when you will be asked what you want to do, and the Android SDK and AVD Manager interface will appear...

Go to the "Settings" section and make sure you check the "Force https://..." box. Click the "Save & Apply" button....

Now go to the "Installed Packages" section and click the "Update All" button. A window will appear with all the available updates. Click the "Install Accepted" button...

...and wait for the packages to be downloaded and installed. It will take a while if you have a slow bandwidth, so go see a movie or something until it finishes...

Close the update window when it's done and you will see all the installed SDKs in the "Installed Packages" section.

And now, let's create the virtual device. Go to the "Virtual Device" section and click the "New" button. In the new window do the following:

- put a name to the device;
- select a target (Android system);
- put the size for the SD Card;
- add the hardware you want have in the emulator.

It should look something like this...

Click the "Create AVD" button when you're done setting up the virtual device and wait for it to finish. It takes about 1 minute, and you'll be notified by a pop-up...

Note: In the above setup, we've created a virtual device for Android 2.0.1 with a 2 GB SD card and the following hardware components: SD Card, GPS, Accelerometer, Track-ball and touch-screen.

Now click the "Start" button, and the "Launch" button from the next dialog, and the emulator will start...

To make things a lot simpler let's create a desktop shortcut, so you won't have to open the terminal every time and type some command, in order to start the Android emulator. Therefore, right-click on your desktop and choose the "Create Launcher..." option...

In the Create Launcher window, type "Android Emulator" (without quotes) in the Name field, and paste the below line in the Command field. Optionally, you can also put a nice icon if you click the icon button on the left...

/home/YOURUSERNAME/android-sdk-linux_86/tools/emulator @softpedia

Note: Please replace YOURUSERNAME and the name of the Android Virtual Device (softpedia in our case) with your USERNAME and the name you gave to the virtual device. DO NOT REMOVE the @ sign.

Step 3 - Run applications in Android

All you have to do now is double-click that desktop shortcut you've just created. The Android emulator will start. Wait for the operating system to load...

When the Android operating system has loaded, you can install and test applications. If you are used with the Android platform, you already know how to do that, but if this is your first time... follow the next instructions.

Click the Browser icon, wait for the browser to load and click Menu -> Go to URL. Enter the address from where you can download an Android application with the apk extension. For example, we've easily installed Android's Fortune from Launchpad...

...all you have to do is follow the on-screen instructions!

Have fun, and do not hesitate to comment if you want to know more about Android, or if you're stuck somewhere in the tutorial.

USB BackTrack

noreply@blogger.com (David Windarto) — Sun, 13 Sep 2009 21:36:22 PDT

BackTrack is a Live Linux distribution based on SLAX that is focused purely on penetration testing. Distributed by remote-exploit.org, BackTrack is the successor to Auditor. It comes prepackaged with security tools including network analyzers, password crackers, wireless tools and fuzzers. Although originally designed to Boot from a CD or DVD, BackTrack contains USB installation scripts that make portable installation to a USB device a snap. In the following tutorial, we cover the process of installing BackTrack to a USB flash drive from within a working Windows environment.

How to install BackTrack to a USB device:

Note: USB installation of BacktTack performs like the Live CD. Currently a persistence BackTrack feature is outside the scope of this tutorial.

1. Download the (Portable Backtrack) USB BackTrack (Extended) version
2. Extract the Boot and BT3 folders to the root of your USB device
3. Navigate to the Boot folder on your "USB device" and click bootinst.bat (click continue if the following error appears)

4. Follow the onscreen instructions to make the device bootable
5. Once the USB install script has finished, reboot your computer and set your BIOS or Boot Menu to boot from the USB device

Internet Connection Sharing using "Firestarter " in LINUX

noreply@blogger.com (David Windarto) — Sun, 10 May 2009 18:08:06 PDT

Firestarter is a GPL-licensed graphical firewall configuration program for iptables, the powerful firewall included
in Linux kernels 2.4 and 2.6. Firestarter supports network address translation for sharing an Internet connection
among multiple computers, and port forwarding for redirecting traffic to an internal workstation. Firestarter's
clean and easy to use graphical user interface takes the time out of setting up a custom firewall.

Firestarter has the ability to share the firew all host's Internet connection among all the computers on your
local netw ork. This is done through a technique called Netw ork Address Translation, or NAT. To the outside
w orld the cluster of machines w ill look like a single machine w ith a single IP address.

Step by Step How to Install "FIRESTARTER"

1. Synaptic Package Manager

Click on Firestarter --->MarkInstall--->APPLY

2. Running Firestarter as below

3. Choose Type Internet Connection base on your Network Method

Choose TOP one if your method such as ADHOC
Choose DHCP as below Method Setting

The physical setup and network device settings
==============================================
The procedure for setting up a netw ork using
connection sharing is essentially the same
w hether you have only tw o computers or a more
complex netw ork w ith hubs or sw itches
connecting multiple computers. For this example
w e w ill be assuming that the Internet connected
device on the firew all is an Ethernet card, but a
modem or ISDN w ill w ork too.
The Firew all/gatew ay machine connected to the
Internet w ill need tw o netw ork cards and the
clients need one each.
The first netw ork card in the firew all, the external interface, w ill be the one physically connected to the
Internet. This card is usually automatically configured w ith DHCP. The second netw ork card in the firew all,
the internal interface, w ill be connected to the client machines via either a crossover cable if the connection
goes directly to another computer, or regular cable if you have a hub or sw itch.
The internal interface of the firew all needs to be
statically configured. There are many w ays to
configure a netw ork interface depending on the
distribution you use. Fedora and Red Hat Linux ship
w ith a simple command line tool called netconfig and a
more sophisticated graphical tool called system-config-network. system-config-network w orks better w ith
multiple netw ork cards in the same machine, so w e recommend you try it. Other distributions include their
ow n configuration tools, for example in SuSE you w ould use the Yast program.
No matter how you decide to configure the netw ork cards, these are settings you should enter:

For the external device (usually eth0):

Enable dynamic IP configuration (DHCP)
That's it. You're done, don't touch this card further.
The internal device (usually eth1):
Disable dynamic IP configuration
IP address: 192.168.0.1
Netmask: 255.255.255.0
Default gatew ay (IP):
Any changes you make w ill take effect after a reboot, or more elegantly after a restart of the netw ork
services (run "/etc/init.d/network restart" as root in most distributions).

Configuring the clients
========================

There are tw o w ays to configure the clients. The more elegant and in the long run easier w ay is to run a
DHCP service on the firew all. A DHCP server distributes the netw ork settings such the IP address, the
default gatew ay, nameservers, etc. at run time to the each client. The alternative to using a DHCP server is
to configure every client manually.
Using the DHCP service is as easy as simply enabling it in Firestarter. For more information about the service
and how to configure it, refer to the section on configuring the DHCP server.
When using DHCP, the clients need only be configured to use dynamic IP configuration. No other settings
need to be changed.
Configuring the clients manually
If you do not w ish to use the DHCP service, configure the netw ork devices of the clients to use the follow ing
settings:
Disable dynamic IP configuration
IP address: 192.168.0.2 to 192.168.0.254, w ith each client using an unique IP
Netmask: 255.255.255.0
Default gatew ay (IP): 192.168.0.1
Primary nameserver: Set this to the same nameserver as used on the firew all. You can see the correct
setting in the /etc/resolv.conf file on the firew all.
Restart the network service and you're done.

Using BULK COLLECT With a SELECT INTO Statement
-------------------------------------------------
You can use the BULK COLLECT clause with a SELECT INTO or FETCH statement to retrieve a set of rows into a collection of records.

DECLARE

TYPE employeeset IS TABLE OF employees%ROWTYPE;

underpaid EMPLOYEESET; -- Holds set of rows from EMPLOYEES table.

CURSOR c1 IS

SELECT first_name,

last_name

FROM employees;

TYPE nameset IS TABLE OF c1%ROWTYPE;

some_names NAMESET; -- Holds set of partial rows from EMPLOYEES table.

BEGIN

-- With one query, we bring all the relevant data into the collection of records.

SELECT *

BULK COLLECT INTO underpaid

FROM employees

WHERE salary < 5000

ORDER BY salary DESC;

-- Now we can process the data by examining the collection, or passing it to

-- a separate procedure, instead of writing a loop to FETCH each row.

dbms_output.Put_line(underpaid.COUNT

||' people make less than 5000.');

FOR i IN underpaid.FIRST.. underpaid.LAST LOOP

dbms_output.Put_line(Underpaid(i).last_name

||' makes '

||Underpaid(i).salary);

END LOOP;

-- We can also bring in just some of the table columns.

-- Here we get the first and last names of 10 arbitrary employees.

SELECT first_name,

last_name

BULK COLLECT INTO some_names

FROM employees

WHERE ROWNUM < 11;

FOR i IN some_names.FIRST.. some_names.LAST LOOP

dbms_output.Put_line('Employee = '

||Some_names(i).first_name

||' '

||Some_names(i).last_name);

END LOOP;

END;

How to Find duplicate copies of files Using fdupes

noreply@blogger.com (David Windarto) — Tue, 03 Feb 2009 20:13:36 PST

FDupes uses md5sums and then a byte by byte comparison to find
duplicate files within a set of directories. It has several useful options
including recursion.
Install fdupes in ubuntu
--------------------------
sudo aptitude install fdupes
----------------------------

This will install all the required packages for fdupes
Using fdupes

Fdupes syntax
--------------
-r --recurse - include files residing in subdirectories
-s --symlinks - follow symlinked directories
-H --hardlinks - normally, when two or more files point to the same disk area they are treated as nonn-duplicates; this
option will change this behavior
-n --noempty - exclude zero-length files from consideration
-f --omitfirst - omit the first file in each set of matches
-1 --sameline - list each set of matches on a single line

-S --size - show size of duplicate files
-q --quiet - hide progress indicator
-d --delete - prompt user for files to preserve, deleting all others
-v --version - display fdupes version
-h --help - displays help
Fdupes Examples
1) fdupes -r ./stuff > dupes.txt
Then, deleting the duplicates was as easy as checking dupes.txt and deleting the offending directories. fdupes also can prompt
you to delete the duplicates as you go along.
2) fdupes -r /home/user > /home/user/duplicate.txt
Output of the command goes in duplicate.txt
fdupes will compare the size and M D5 hash of the files to find duplicates

7 reasons why Windows will not wreck Ubuntu

noreply@blogger.com (David Windarto) — Wed, 21 Jan 2009 00:28:36 PST

One of our competitors has a review of the Windows 7 beta which claims that desktop Linux is doomed — doomed!

Not exactly. Not even approximately.

First let’s understand what 7’s target is. It’s not so much desktop Linux as a particular Linux distro — Ubuntu — that targets the desktop.

Some of these reasons are technological, others social. But the biggest reason is a business reason:

1. Ubuntu has an entrepreneur at the helm. Microsoft beat IBM because it had Bill Gates up against a bunch of suits. Now Microsoft is a bunch of suits and Ubuntu has Mark Shuttleworth.
2. Ubuntu has more server compatibility. Linux continues to beat Windows on the server, and servers (in the form of clouds) are becoming dominant over clients.
3. Ubuntu’s friends will not desert it. HP and Dell have gotten a taste of freedom from Microsoft tyranny. They won’t give that up easily. They will continue seeking product line niches where Ubuntu can succeed.
4. The Netbook will continue to evolve. The “no moving parts” PC is still at Version 1.0. There is a niche for a cheap, profitable “online machine” that can be used in Airports, hotel rooms and sandy deserts.
5. Applications will come. It’s true there are more Windows apps than Linux, by a logarithmic factor. But many are being ported, and the developed world will create many more.
6. Windows is losing the mobility wars. Linux is playing well, Apple is winning big, RIM is hanging in. Where’s Windows? PCs are servers to mobile clients. The clients will tire of waiting.
7. The open source model. Software development has become like the old Steve Jackson game Ogre, and Microsoft’s the Ogre. Ubuntu and other open source pieces are small, but there are a lot of them, and they can work together. Or as Kermit said in The Muppet Movie “who are your friends, Doc?”

This does not mean that Microsoft will cease to be a desktop player, that Ubuntu is going to take over. Far from it. Ubuntu will retain enough interest to stay in the game, that’s all it needs to do.

Ubuntu is doing fine with its present market share. How much more can it get over the next year? Perhaps just a little. I suspect this will be a year when desktop Linux consolidates around Ubuntu, so some gain is nearly assured.

Microsoft will also not disappear under the open source onslaught, just as IBM did not disappear under the weight of Microsoft. But it will change.

It will be fun to watch how it changes, and when. It has yet to see the need, but when Ubuntu fails to fall under the weight of Windows 7 perhaps it will.

NETSTAT in Linux

noreply@blogger.com (David Windarto) — Tue, 09 Dec 2008 17:35:41 PST

NETSTAT (network statistics) is useful for tracking down network problems. Use NETSTAT to
troubleshoot incoming or outgoing packet errors or to verify the presence of needed routes.
If you type netstat at the MS-DOS prompt, you see the protocol used, the name and local
address of the computer, and any connected computers and their current state

Netstat –a Displays all connections and listening ports
Netstat –e Displays Ethernet statistics
Netstat -n Displays addresses and numbers in numerical format
Netstat -s Displays the statistics of TCP/IP protocols: TCP, UDP, and IP

usage: netstat [-anv] [-f address_family]
netstat [-g | -p | -s] [-n] [-f address_family] [-P protocol]
netstat -m
netstat -i [-I interface] [-an] [-f address_family] [interval]
netstat -r [-anv] [-f address_family]
netstat -M [-ns] [-f address_family]
netstat -D [-I interface] [-f address_family]

You should now see something like this on your screen:

Starting XAMPP 1.6.8a...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.

Ready. Apache and MySQL are running.

4. http://localhost

5. Mysql Area --> http://localhost/phpmyadmin

6. Now try put File Projects as oscommerce in /opt/lampp/htpdocs

Here a list of missing security in XAMPP:

1. The MySQL administrator (root) has no password.
2. The MySQL daemon is accessible via network.
3. ProFTPD uses the password "lampp" for user "nobody".
4. PhpMyAdmin is accessible via network.
5. Examples are accessible via network.
6. MySQL and Apache running under the same user (nobody).

To fix most of the security weaknesses simply call the following command:

/opt/lampp/lampp security

Parameter Description
start Starts XAMPP.
stop Stops XAMPP.
restart Stops and starts XAMPP.
startapache Starts only the Apache.
startssl Starts the Apache SSL support. This command activates the SSL support permanently, e.g. if you restarts XAMPP in the future SSL will stay activated.
startmysql Starts only the MySQL database.
startftp Starts the ProFTPD server. Via FTP you can upload files for your web server (user "nobody", password "lampp"). This command activates the ProFTPD permanently, e.g. if you restarts XAMPP in the future FTP will stay activated.
stopapache Stops the Apache.
stopssl Stops the Apache SSL support. This command deactivates the SSL support permanently, e.g. if you restarts XAMPP in the future SSL will stay deactivated.
stopmysql Stops the MySQL database.
stopftp Stops the ProFTPD server. This command deactivates the ProFTPD permanently, e.g. if you restarts XAMPP in the future FTP will stay deactivated.
security Starts a small security check programm.

Good Luck :-)

Apt-Get -----> History Ubuntu/Mint/Blankon...

noreply@blogger.com (David Windarto) — Wed, 26 Nov 2008 22:28:42 PST

The apt-get command is a powerful command-line tool used to work with Ubuntu's Advanced

Packaging Tool (APT) performing such functions as installation of new software packages, upgrade of existing software packages, updating of the package list index, and even upgrading the entire Ubuntu system.

Being a simple command-line tool, apt-get has numerous advantages over other package management tools available in Ubuntu for server administrators.

Some of these advantages include ease of use over
simple terminal connections (SSH) and the ability to be used in system administration scripts,
which can in turn be automated by the cron scheduling utility.

Some examples of popular uses for the apt-get utility:

• Install a Package: Installation of packages using the apt-get tool is quite simple.

For example, to
install the network scanner nmap, type the following:
sudo apt-get install nmap

• Remove a Package: Removal of a package or packages is also a straightforward and simple process.

To remove the nmap package installed in the previous example, type the following:

sudo apt-get remove nmap

Multiple Packages: You may specify multiple packages to be installed or removed,
separated by spaces.

• Update the Package Index: The APT package index is essentially a database of available
packages from the repositories defined in the /etc/apt/sources.list file. To update the local package index with the latest changes made in repositories, type the following:

sudo apt-get update

• Upgrade Packages: Over time, updated versions of packages currently installed on your computer
may become available from the package repositories (for example security updated).

To upgrade
your system, first update your package index as outlined above, and then type:

sudo apt-get upgrade

If a package needs to install or remove new dependencies when being upgraded, it will not be upgraded by the upgrade command. For such an upgrade, it is necessary to use the dist-upgrade
command.
Also, you may upgrade your entire Ubuntu system from one revision to another with dist-upgrade.
For example, to upgrade from Ubuntu version 5.10 to version 6.10, you would first ensure
the version 6.10 repositories replace the existing 5.10 repositories in your computer's

/etc/apt/sources.list, then simply issue the apt-get update command as detailed above, and
finally, perform the actual upgrade by typing:

sudo apt-get dist-upgrade

After a fairly considerable amount of time, your computer will be upgraded to the new revision.
Typically, some post-upgrade steps would be required as detailed in the upgrade notes for the
revision you are upgrading to.

Actions of the apt-get command, such as installation and removal of packages, are logged in the

/var/log/dpkg.log log file.

For further information about the use of APT, read the comprehensive Debian APT User

Manual

START THE GRAPHIC WITHOUT INSERT LOGIN AND PASSWORD

noreply@blogger.com (David Windarto) — Sun, 23 Nov 2008 17:07:34 PST

Here is 2 Method , pls go through one by one

1)This thing has been tryied on redhat 7.1
------------------------------------------
-Modify the file /etc/sysconfig/desktop
Insert the name of desktop that will start, es. fvwm2
Modify the file /etc/X11/xinit/Xclients replacing the name of predefined desktop (GNOME)
with fvwm2.
Modify the file /etc/X11/xinit/xinitrc.d/xinput replacing the name of desktop predefined
(GNOME) with fvwm2.
Create the file .xinitrc inside the directory of the user or root and write inside:
fvwm2
Modify the file /etc/rc.d/rc.local inserting on the first row (or replacing the first row) with:
#!/bin/bash
After this row write the path of file .xinitrc and after the written startx, resuming:
#!/bin/bash
cd /root & startx
or
cd /root & startx fvwm2
At this point reboot pc and see the result.

2)Inserting a user with the home and the group of belongings.
-------------------------------------------------------------
Modify the file /etc/profile
inserting these dates:
HOME="/username"
export HOME
Save the file.
Enter in /etc/inittab disabling from row Run gettys until the end putting a # in front of all the
rows.
Over the row Run getty insert another row:
1:12345:wait:/bin/bash -login
Save the file and reboot. At start enter such as user withou insert username and password.
If inside /home/user we insert a file .xinitrc where we write graphic desktop to start for
example fvwm2. It's possible to copy the file /etc/X11/fvwm2/system.fvwm2rc inside
/home/user and rename it in .fvwm2rc
Inside file .bash_profile at the end write startx, so will start the graphic automatically.
Rebooting the pc we will enter such as user and automatically will start the X chosen.
