Bagaimana Menggunakan Linux Backtrack

Ok,banyak yang bertanya2 cara menggunakan linux backtrack.
Disini saya akan mengulas "sedikit" tentang cara menggunakan linux backtrack.
Download dulu linuxnya yang berbentuk livecd download backtrack2
Lalu burn menjadi livecd "caranya"
Booting komputer via cd (jgn lupa setting dibios boot first cd)
=============================================================

-------------------------------------------------------
:: Backtrack 2.0 ::
BackTrack
login: root
password: toor
--------------------------------------------------------
*** When finished, hit Ctrl+Alt+Delete and
wait until the computer reboots ***
--------------------------------------------------------
slax login:_
=============================================================
Lalu login masukkan login:root dan password:toor
Setelah itu Ketikkan xconf
=============================================================
Trying to autoconfigure Xwindow system, please wait...
creating /etc/X11/xorg.conf...
all done. Run startx now.
=============================================================
Atau langsung ketik startx
atau lo bisa ketik guifast
ok sekarang lo dah masuk ke linux backtracknya.


Biasanya backtrack akan men set network secara dhcp tapi kalau ngga caranya gini:
setting IP secara Dhcp.
caranya:
ketik "dhcpd eth0"
(untuk eth0 ini tergantung dari lan card yang lo gunain)
untuk memastikan ketik ifconfig


setting IP secara static.
caranya:
ketik "ifconfig eth0 192.168.1.2/24" ->setting IP dan subnet
ketik "route add default gw 192.168.1.1" -> setting gateway
ketik "echo nameserver 192.168.1.1 > /etc/resolve.conf" -> sett dns
untuk memastikan ketik ifconfig


Jangan lupa untuk ganti passwordnya
caranya:
ketik "passwd" masukkan pasword yang "kuat"


untuk memunculkan bash command bisa ketikkan:
leetmode atau yakuake


cara menginstal backtrack ke harddisk beserta pilihan dual boot:
jalanin "Qtparted" dari linux tsb dari bash command
nanti didalem qtparted tsb terdapat partisi (kayak fdisk di win)
ex: 4Giga
partisi pertama 3.5Giga
partisi Kedua 0.5Giga
yang partisi pertama di format ext3
yang partisi kedua di format linux-swap
(disini qtparted suka ngaco lo buka shell umount ato mount hda1 dan hda2)
hal ini supaya qtparted bisa di create ato format setelah itu jangan lupa commit di toolbarnya
setelah itu buka "backtrack installer" pilih "install backtrack to hda2" hal ini tergantung hdd lo
klo sata biasanya namanya sda klo ide biasanya namanya hda (hda1 buat windows and hda2 buat linux ext3) tunggu sampai 100% setelah itu restart and boot ke linux automatically
dari linux lo buka shell masuk ke folder /etc ketik "nano lilo.conf" trus di lilo tsb tambah ini diatas image
==============================
other = /dev/hda1
label = Windows
table = /dev/hda
==============================
jadi nya klo gw kayak gini
==============================
boot = /dev/hda
prompt
timeout =1200
bitmap=/boot/splash.bmp
change-rules
reset
vga = 0x317
other = /dev/hda1
label = Windows_Xp
table = /dev/hda
image = /boot/vmlinuz
root = current
initrd = /boot/splash.initrd
label = Backtrack_2
read-only
========================
dah sekarang restart lo bisa liat di waktu pertama boot di minta milih mau w1nd0ws apa linux


Sekarang merubah tampilan pertama backtrack :
caranya:
ketik ini di shell alias command promptnya klo di wnd0ws
bt ~ # nano /etc/issue
dah deh tinggal kreasiin sendiri


ngerubah command line logon menjadi otomatis saat kde start:
bt ~ #nano/etc/inittab
rubah id:3:initdefault: menjadi id:4:initdefault:


membuat leetmode start otomatis
ketik:
cd /root/.kde/Autostart
ln -s /usr/bin/leetmode leetmode
hal ini membuat link leetmode di outostart


membuat yakuake start otomatis
ketik:
cd /root/.kde/Autostart
ln -s /opt/kde/bin/yakuake yakuake
sekarang di KDE hanya tinggal tekan F12


Script dibawah yang membuat otomatis cd-rom keluar:
ketik:
cd /etc/rc.d
ketik:
nano rc.6
cari code yang seperti ini:
# eject cdrom devices
. ./usr/lib/liblinuxlive
#echo "Ejecting all CDROMs..."
#list_cdrom_devices while read DEVICE; do
# cdrecord dev=$DEVICE -eject >/dev/null 2>/dev/null
# can't use eject because it's not working with our kernel
# eject -s $DEVICE >/dev/null 2>/dev/null
#done
#echo "========================================"
#echo "It's safe to switch the computer off now"
#echo -ne "Press Enter to $command "
#read junk


cara merubah pesan pertama kali boot:
nano /etc/issue


cara menginstal java client:
INSTALL JAVA CLIENT
http://java.com/en/download/manual.jsp
- Download Java Linux (self-extracting file)
- cd opt
- mkdir java
- cp /tmp/jre-6u1-linux-i586.bin /opt/java
- cd java
- ls
- chmod a+x jre-6u1-linux-i586.bin
- ls -l
- ./jre-6u1-linux-i586.bin
- yes
- ls
http://java.com/en/download/help/5000010500.xml#enable
- cd /opt/firefox/plugins
- ln -s /opt/java/jre1.6.0_01/plugin/i386/ns7/libjavaplugin_oji.so
- Firefox-Preferences-Content-Enable java
Good luck.


secure shell daemon
caranya:
ketik "sshd-generate"
ketik "/usr/sbin/sshd"
ketik "netstat -ant grep 22"


Bikin http server klo bahasa neubenya bikin web server
caranya:
ketik "apachectl start" ->fungsinya hidupin apache server buat web
ketik "netstat -ant grep 80" ->cek apakah port 80 aktif
ketik "apachectl stop" ->fungsinya matiin apache server
ketik "netstat -ant grep 80" ->cek lagi


bikin file tansfer protocol atau kerennya ftp server
caranya:
ketik "atftpd --daemon --port 69 /tmp/"
ketik "netstat -anu grep 69"


bikin vnc server biasanya dipake buat ngeremote
caranya:
ketik "vncserver"
masukkan 8digit pass ato lebih
ketik "netstat -ant grep 5901"

caranya bikin dual boot secara otomatis (dikonfigurasi sendiri sama linuxnya)
tinggal ketik "liloconfig" tinggal ikutin perintahnya aja

konfigurasi IP memakai netconfig
di shell tinggal ketik "netconfig" aja

buat tanem ip
masuk k etc ubah file rc.inet1 "nano /etc/rc.d/rc.inet1.conf"
rubah:
# Config information for eth0:
IPADDR[0]="xxx.xxx.xxx.xxx"
NETMASK[0]="255.255.255.xxx"
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""
# Default gateway IP address:
GATEWAY="xxx.xxx.xxx.xx"
jangan lupa ketik
bt rc.d # rc.inet1

bikin techmon kayak leetmode di BT3
caranya di sheel ketik "superkaramba" trus download filenya jadi degh di desktop

cara install paket yang berextention .tgz
tinggal ketik:
"installpkg namapaket.tgz"

mengextrax file .gz
"tar -xzvf namafile.gz"
$ tar -zxvf nama_file.tar.gz -C /folder/tujuan/

mengextrax file .bz2
"tar -xjvf namafile.bz2"

bagaimana mengupdate slackware yang ada di backtrack pake slapt-get:
ketik ini di shell "slapt-get --update" setelah itu ketik "slapt-get --upgrade"
ketik 'kwrite /etc/slapt-get/slapt-getrc"
tambahin:
SOURCE=http://darkstar.ist.utl.pt/slackware/
buat download updatean nya
program yang lain yaitu:
Kslackcheck buat update slack juga
ini downloadnya kslackcheck
cara installnya tinggal "installpkg namafile.tgz" selesai lihat di system
nambah fast-track di BT2
caranya download dulu fast-track nya
lalu masukkan ke directory "/pentest/misc/"
setelah itu ketik "chmod 755 fast-track.py"

konfigurasi sound dibacktrack
tinggal ketik "alsaconf" ikutin perintahnya setelah selesai ketik "alsamixer" setelah setting suara ketik "alsactl store" buat nyimpen

ini hal aneh kok pentest ada officenya
yahhh gpp degh namanya juga belajar
pertama download officenya di open office

BackTrack 3 USB install and Intel 3945 packet injection

BackTrack 3 USB install and Intel 3945 packet injection
Posted March 9th, 2008 by williamw

I am late announcing this as the official beta has been out since December, however my circumstances recently have changed such that I now have a USB drive. I have been messing around with Backtrack for almost a year and a half now — mostly with the wireless tools — and have been impressed with the powerful arsenal this little bad boy gives you. The best part is that it is FREE!! If you aren’t sure what BackTrack is, I suggest you click here for more information. This will knock your socks off!

For the rest of us who know what it is, I will give you the break down of what you need to do to install BT3 on a USB drive. If you are like me then you are frustrated that your nice laptop comes with such a non-hacker friendly wireless card, the Intel 3945abg. I mean it is a fantastic card for ‘normal’ wireless use–however if one wants to get a little more aggressive with it, than it is near to impossible to allow this card to go into promiscuous mode or to actively inject packets wirelessly. Not to fear though, I will guide you through the steps needed to accomplish both these things.

**The author recognizes there are a variety of methods to go about doing this, however the document procedure below is the one that works best for the author. To follow these EXACT instructions you will need:

1- Computer with Linux

2- Computer with Windows

Step #1

We need to prepare the usb drive for the installation — the usb drive that I used was 8 gig in size, so I wanted to have the majority of the drive available to me as a portable storage space as well as allowing the drive to remain bootable–so my exact process might be a little different than your process. I will try to accommodate for both scenarios.

Ok first off we are going to assume that you don’t have anything on the usb drive (if you do please temporarily move it to another location). Now we need to remove any existing partitions from the USB drive and essentially start from scratch. Insert the USB device into the computer running linux; after the device is recognized and mounted we need to unmount the device from the system so that we can manipulate the partitions. To do this open a terminal window and enter the following command:

umount /dev/sdb [where sdb is the name of the usb drive]

**To find what the drive name is, type: ‘dmesg | tail’ immediately after plugging in the device.

After unmounting the device we want to now use the program called fdisk. From the terminal window type;

sudo fdisk /dev/sdb

[your prompt should change to look like this]

The number of cylinders for this disk is set to 14593.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help):

press ‘p’ to show all the current partitions on the device — I am assuming that there is only one partition on the device, if there are more than one listed then you will need to duplicate the following steps until there are no more partitions showing on the disk.

d [to delete partition]

w [to write changes to disk]

After writing the changes to disk you can press ‘p’ again to confirm that there are no more partitions available on the disk. Now that the device is 100% unallocated space we need to repartition the disk so that we can have a partition for BackTrack 3 to be installed to and another partition to save any changes made to BackTrack and then the third partition is going to be used as the “storage space” that will act as a normal USB drive. Although fdisk is capable of creating new partitions on the device I am going to introduce another program that has a GUI front end that does a good job at creating and formatting the new partitions in one swoop. The program that we will be using is Gparted. If you are using Ubuntu you can install this program from the terminal window by typing:

sudo apt-get install gparted

After installing Gparted we need to start it so in the terminal type:

sudo gparted

This should know open a small rectangle window that displays your current drives partition information. In the upper right hand corner there should be a drop down menu that will allow you to change your device to the USB drive (/dev/sdb) that we just wiped out. After choosing that device you will see that there is no partitions available on the drive and that all space is counted as unallocated. Select the unallocated space and then choose “New”. We need to create a minimum of two partitions, or three if you want some space left on the disk to use as a normal USB drive. Below are the partition sizes and filesystem types I used.

sdb1 — size 6.5 gig — FAT32 [Normal USB storage space]

sdb2 — size 1 gig — FAT32 [BackTrack3 source files]

sdb3 — size 512 MB — EXT2 [BackTrack3 ‘changes’]

**Note you must create a FAT32 parition for the BackTrack3 files to exist on or else the boot script will not run properly

After getting the partitions into the correct order make sure you tell gparted to ‘Write’ the changes to disk. If all goes well gparted will inform you of a success, if not start over at wiping the disk.

Ok so now we have our partitions and file systems it is time to get install BackTrack! First you need to download the installation files specific to a USB installation, click here to get the files. Make sure you get the USB Version. After downloading the the file, extract the files onto the second partition (in my case sdb2). So in the root of the drive I should have two folders “boot and BT3″. After extracting the files we need to run a installation script that will make the first partition bootable. Go into the boot folder and you should see a file called “bootinst.sh” (if you are going to run the script from windows look for the file called “bootinst.bat”). Now we need to run that script file. From the terminal type the following

sudo ./bootinst.sh

Follow the prompts and that should now enable the first partition to be bootable drive. Now we need to configure BackTrack to allow us to save any changes that we make to disk. Once again go into the ‘boot’ folder and then into the ’syslinux’ folder. Inside of that directory there is a file called ’syslinux.cfg’. Open that file up with your favorite text editor. We need to find the section that says “LABEL pc change”, in that section there is a line that says

APPEND vga=0×317 initrd=/boot/initrd.gz ….

And we need to change that line so that it now reads

APPEND vga=0×317 changes=/dev/sdb3 initrd=/boot/initrd.gz

be careful of any extra commas or white spaces, they will disrupt the syntax of the command

(**Note this file displays the different ways that BT3 can be started, because I want to start BT3 in “persistent change” mode (aka it will always save any changes made) I actually moved the entire ‘pc change’ section to the top of the file so that by default BT3 starts in “persistent change” mode. )

After saving the syslinux.cfg file we need to do one last thing — on the third partition that we made (/dev/sdb3) that contains the .EXT2 filesystem we need to create a folder called ‘changes’ in the root level of that partition. Linux is case sensitive so make sure that the folder is called EXACTLY ‘changes’. If your partition numbers are different than what is listed here you need to make the corresponding changes in the syslinux.cfg file to reflect the actual partition number where the ‘changes’ folder is stored. You also need to make sure that your ‘changes’ folder has the proper permissions configured for it; the author has his configured for 777, however this potentially leaves a security problem with respect to this drive. Only configure 755 permissions if you are doing this for testing purposes only. From the terminal window, inside of the /sdb3 root directory issue the following command:

chmod -R 755 changes

ls -l (to confirm that there is total ‘w r x’ permissions on the folder)

Phew well now that is taken care of we need to now enable our intel 3945 wireless card to support monitor mode and packet injection. To do this execute the following commands from the terminal.

1. Download the drivers

mkdir intel-drivers && cd intel-drivers

wget http://homepages.tu-darmstadt.de/~p_larbig/wlan/ipwraw-ng-2.0.0-10072007...

2. Extract the drivers

tar -xjf ipwraw-ng-2.0.0-10072007.tar.bz2

cd ipwraw-ng

3. Compile & Install & Blacklist from startup

make && make install

make install_ucode

echo “blacklist ipwraw” | sudo tee /etc/modprobe.d/ipwraw

depmod -ae

4. Load new modules and put intel 3945 into monitor mode

modprobe -r iwl3945

modprobe ipwraw

5. Test packet injection

aireplay-ng –test wifi0

6. Resort to normal mode

modprobe -r ipwraw

modprobe iwl3945

Well now you have the ultimate setup — BackTrack 3 on a stick and an internal wireless card that supports packet injection, what more could you want? Well ok, maybe there are just a few things . . . Stay tuned and I will keep you updated on new programs and tools I find using BT3.

cd ipwraw-ng

3. Compile & Install & Blacklist from startup

make && make install

make install_ucode

echo “blacklist ipwraw” | sudo tee /etc/modprobe.d/ipwraw

depmod -ae

4. Load new modules and put intel 3945 into monitor mode

modprobe -r iwl3945

modprobe ipwraw

5. Test packet injection

aireplay-ng –test wifi0

6. Resort to normal mode

modprobe -r ipwraw

modprobe iwl3945

Well now you have the ultimate setup — BackTrack 3 on a stick and an internal wireless card that supports packet injection, what more could you want? Well ok, maybe there are just a few things . . . Stay tuned and I will keep you updated on new programs and tools I find using BT3.
