Free 5-minute International Calls

by HydTech on Nov.06, 2009, under Uncategorized

You’ve heard of 1800-FREE-411.  It’s a 411 directory service that doesn’t charge you the 1.49 that mobile companies do.  They started a new promotion which allows you to call them and dial any International number and talk for 5 minutes.  Why free? Well, the catch is that you have to listen to their advertisement before placing your call.

Now the offer is valid for any person who can dial a 1800 number and if you live in the US, then the call is free, however, you can dial 1800 numbers free from Internet phones like Yahoo messenger, gizmo or skype.

Installing Windows 7 on my Lenovo S10 Multiboot

by HydTech on Nov.03, 2009, under Uncategorized

Las time I installed BackTrack 4 using Unetbootin. This time I Installed Windows 7 to my Hard drive without using an external CD player.  Instead I used an external hard drive.  Can also be done with USB.

I already have Ubuntu installed so I downloaded Unetbootin and I obtained the Windows 7 DVD in ISO format.

I fired up Gparted and made a 10GB partition for Win 7 and formatted the partition used for install and the external hard drive with NTFS.

Changed the permissions of the Unetbootin file:
chmod 777 /home/user/Desktop/unetbootin-linux-372

Fired up Unetbootin, entered my password and selected the Win7  iso and changed the type to hard disk.  Here make sure you select the right partition of your external drive.  you can type df -h in terminal to make sure.:
bt41

Press Ok and wait
bt4

Reboot and have your BIOS boot from external drive or hold down F12 to select.

reboot

The installation is self explanatory.  I installed the WIndows 7 to a logical partition.  After installation, I had to boot up into an Ubuntu live installation and fix grub like I did here.  Opened menu.lst for editing the grub menu:

sudo gedit /boot/grub/menu.lst

Add this to the end of the file and close:
title Microsoft Windows 7
root (hd0,0)
makeactive
chainloader +1

BackTrack 4 MultiBoot on my Lenovo S10 with Unetbootin frugal install

by HydTech on Sep.25, 2009, under Uncategorized

Last time I installed BT3 on mt Lenovo X60 here. This time I tried a different method without using the external CD player.

I already have Ubuntu installed so I downloaded Unetbootin and the BackTrack 4 Beta ISO.

I fired up Gparted and made a 6GB partition for BT4 and formatted it with reiserfs to avoid the ext3 checks.

Changed the permissions of the Unetbootin file:
chmod 777 /home/user/Desktop/unetbootin-linux-372

Fired up Unetbootin, entered my password and selected the BT4 iso and changed the type to hard disk:
bt41

Pressed Ok and let it do its thang
bt4

Reboot

reboot

When it restarts you have to select Unetbootin from the Grub menu and this will boot into Backtrack. My BackTrack partition I will install on is sda7 and BT4 automatically mounted it to /mnt/sda7

if not, you can mount your drive by typing:
mkdir /mnt/sda7
mount /dev/sda7 /mnt/sda7
replace sda7 with your partition

now, copy the required files from the pseudo-live cd to the hard drive:

cp -pr /{bin,dev,home,pentest,root,usr,boot,lib,etc,opt,sbin,var} /mnt/sda7/
mkdir /mnt/sda7/{mnt,proc,sys,tmp}
mount –bind /dev/ /mnt/sda7/dev/
mount -t proc proc /mnt/sda7/proc/

The installation is done, now you can reboot back into Ubuntu and load Unetbootin again. It will ask you to remove the changes it made earlier and select yes. Close unetbootin and open menu.lst for editing the grub menu:

sudo gedit /boot/grub/menu.lst

Add this to the end of the file and close:

title BackTrack 4 KDE
rootnoverify (hd0,6)
kernel /boot/vmlinuz vga=0×361 root=/dev/sda7 ro quiet splash autoexec=xconf;kdm
boot

title BackTrack 4 shell
root (hd0,6)
kernel /boot/vmlinuz ro root=/dev/sda7 vga=0×361
boot

My next post will be about getting the Broadcom wireless on the Lenovo S10 to work in BT4.

Sign apk package files for publishing in the Android market with keytool and jarsigner on Ubuntu

by HydTech on Aug.13, 2009, under Uncategorized

Once you’ve completed your package with Eclipse and you want to publish it to the android market, google requires that you sign it.  For this step you need two tools.  Keytool and jarsigner can be obtained through JDK.

Open up terminal and install jdk:

sudo apt-get install sun-java6-jdk

Use keytool to make yourself a new key:

keytool -genkey -v -keystore mykeystore.keystore -alias aliasname -keyalg RSA -validity 10000

genkey – generate the key
v – verbose mode
keystore – select name of keystore
alias – creates an alias for the key
keyalg – specifies the encryption algorithm used to generate the key. Ex: RSA, DSA
validity – when should the key expire in days? (google requires like a 50 year expiry)

The keytool will walk you through the process of choosing a password and name.  Once the key is made, you need to sign the apk with jarsigner using this key:

jarsigner -verbose -keystore mykeystore.keystore programfile.apk aliasname

keystore – keystore containing your private key
verbose – verbose mode

You will be prompted for your password. You are ready to go.

Android T-mobile G1 reverse tethering with Wifi

by HydTech on Jun.11, 2009, under Uncategorized

I am currently trying to figure out how to reverse tether a G1 to use an ad-hoc computer-to-computer network. I have Internet at work through ethernet and created an ad-hoc network, but the built in G1 wireless scanner cannot detect ad-hoc networks. There is an application in the marketplace called Wifi Scanner which can detect adhoc networks but it does not have a connect feature. I tried to manually connect using ifconfig in terminal but havent been successful yet. I’ll post updates if I make progress.
