Switch Between IPWRAW and IWL3945

On my previous post, i promise to post about the script to switch between ipwraw driver and iwl3945 driver for intel wireless card. There is the script..


switch to ipwraw :
===========begin=================

#!/bin/bash
echo "Unload Module..."
modprobe -r iwl3945
modprobe -r mac80211
modprobe -r ieee80211
echo "Load ipwraw module..."
modprobe ieee80211
modprobe mac80211
modprobe ipwraw
echo "Activing Monitor mode.."
ifconfig wifi0 up
airmon-ng start wifi0

==========end====================

switch to iwl3945

===========begin=================

#!/bin/bash
echo "Unload iwl3945 Module..."
airmon-ng stop wifi0
modprobe -r ipwraw
modprobe -r iwl3945
modprobe -r mac80211
modprobe -r ieee80211
echo "Load iwl3945 Module..."
modprobe ieee80211
modprobe mac80211
modprobe iwl3945
echo "Checking.."
ifconfig

============end==================

You may be need a few modification to this script.. i hope this will be usefull..

Use IPWRAW as Driver Module For Wi-Fi Card Intel 3945

Wireless Card produced by Intel that i have on my laptop is intel Pro Wireless 3945. Nowadays Intel driver developer release a general driver called iwl3945 that replace the old driver ipw3945. How ever, that driver can't be used to doing some Packet Injection, so some people develop a new driver module that called ipwraw. We can use this module to doing packet injection. That's very nice, but when i use this module i can't browse with my firefox anymore. >.<
I'm sorry if i didn't know the way to do it, but until now, i still can't use ipwraw module to browse. So i make a conclusion that this module is used for injection purpose n monitor mode only. If somebody know the way to do it, please tell me about it..=)
To use ipwraw module, first you must download the driver module and install it on your computer( Search google for the module ) . After that, u must unload the iwl3945, ieee80211 , and mac80211 module. After Finished load the ieee80211 and mac80211 module again, you must also load the ipwraw module. Activated your wireless card on monitor mode to do a packet injection.
In the next post, may be i will post the script to switch between iwl3945 module and ipwraw module. I will also post about how to make the wireless card into monitor mode, and how to do a packet injection.
One more, I'm just a newbie, don't hope to much yach..^^

Instalasi dengan menggunakan Repository

Kemarin minggu, baru aja aku ikut acara ubuntu feisty release party. Acaranya kacau balau seh, mengecewakan.. Udah bela-belain bangun pagi-pagi segala padahal...hiks3...
Untungnya aku dapet satu ilmu yang cukup menarik, yaitu instalasi packet melalui repository.
Caranya mudah kog.. untuk yang kemaren seh, aku dapet yang buat ubuntu.. but ga cuma ubuntu doang, distro-distro lain pun bisa, hanya saja perintah-perintanya yang berbeda.
Untuk ubuntu, pertama kita dapat mencari jenis-jenis packet yang ada di repository yang kita punya dengan perintah
# apt-cache search "nama-packetnya"
gunanya untuk apa? misal kita ingin menginstall ftp server di distro kita, hanya saja kita tidak tahu apa nama packet yang ada di repository yang kita punya ( asumsinya kita tidak terhubung internet lo...=p ) kita dapat jalankan perintah
# apt-cache search ftp
ntar dapet nama-namanya.. misal proftpd
Nah..setelah dapat namanya kita dapat menginstallnya dengan perintah
# apt-get install proftpd
Tunggu beberapa menit dan ftp sudah terinstall.. mudah bukan?

Bagaimana bila kita ingin menambah repository dari CD atau DVD? Kita dapat menggunakan perintah
# apt-cdrom add
secara otomatis packet-packetnya akan ditambah ke repository kita..^^
Bila kita terhubung ke internet, instalasinya akan lebih mudah lagi karena repository yang ada di internet sangat lengkap.. cara-caranya sama seperti diatas..

Mount Your Windows Partition from Linux (NTFS or FAT32)

Sometimes do you want to get your data from windows but that time you use linux? Anyone will feel lazy to reboot their computer just to get data that they need. In linux, you can mount your harddisk even it's a windows partition include fat32 and ntfs.
For fat32 filesystem, linux support it by default. But for ntfs filesystem, you must add some modules.
Step by step to mount it are:
1. List what partition do you have..
# fdisk -l
example :

/dev/hda1 * 1 1275 10241406 83 Linux
/dev/hda2 1276 1402 1020127+ 82 fat32
/dev/hda3 1403 2677 10241437+ 83 ntfs

2. Make a target mount directory
# mkdir /mnt/fat32
# mkdir /mntntfs

3. To mount your fat32 filesystem
# mount -t fat32 /dev/hda2 /mnt/fat32

3. To mount your ntfs filesystem you must install fuse and ntfs-3g first
- Search fuse and ntfs-3g installer from uncle google first..
- Install fuse
# tar -zxvf fuse.X.X.X.tar.gz
# cd fuse.x.x.x/
# ./configure && make && make install
- Install ntfs-3g
# tar -zxvf ntfs-3q.x.x.x.tar.gz
# cd ntfs-3g.x.x.x/
# ./configure && make && make install
After installed all packet, you can mount your ntfs partition now...

4. # ntfs-3g /dev/hda3 /mnt/ntfs

easy right...?he3...
after finished get your data or what ever job you do, you can umount it by:
# umount /mnt/fat32
# umount /mnt/ntfs

Make a Partition with Fdisk

Do you confused how to make partition in linux? Actually we can use software like qparted to make a partition, but we can also make a partition with command line utility like fdisk. Use fdisk to make a partition is not difficult. May be first time you will confused, but after you can use it, fdisk will be a very fast tool to make partition on your linux.
First,you can look your harddisk partition with

[root@fecore ~]# fdisk -l

Disk /dev/hda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 1275 10241406 83 Linux
/dev/hda2 1276 1402 1020127+ 82 Linux swap / Solaris
/dev/hda3 1403 2677 10241437+ 83 Linux
/dev/hda4 2678 4865 17575110 5 Extended
/dev/hda5 2678 3569 7164958+ 83 Linux

After that you can start make your partition,example

[root@fecore ~]# fdisk /dev/hda

The number of cylinders for this disk is set to 4865.
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):

the command are
p
print the partition table

l
list the partition type

n
create a new partition

d
delete a partition

q
quit without saving changes

w
write the new partition table and exit

to see your partition now, type 'p' and press enter..

Command (m for help): p

Disk /dev/hda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 1275 10241406 83 Linux
/dev/hda2 1276 1402 1020127+ 82 Linux swap / Solaris
/dev/hda3 1403 2677 10241437+ 83 Linux
/dev/hda4 2678 4865 17575110 5 Extended
/dev/hda5 2678 3569 7164958+ 83 Linux

make your new partition,press 'n'..

Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-22800, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-22800, default 22800): 13032
The last partition is the extended partition:

change your partition filesystem type,press 't'..
Command (m for help): t
Partition number (1-6): 6
Hex code (type L to list codes):

You can press 'l' to see the list of filesystem type..
after you choose one filesystem,press 'w' to write partition into your harddisk.

finished? not yet...
you must ust mkfs utility to write the file system... example:
you want to make a ext3 filesystem on your partition /dev/hda1..
# mkfs.ext3 /dev/hda1

note: correct me if i'm wrong =)
THE END

Mount Your Flashdisk on Linux

Now, flashdisk is a famous device that usually use by people to save their data. It's all because flashdisk price for any size become cheaper. For people that become a new linuxer, mount a flashdisk can make a problem. In linux, every device readed as file include our flashdisk. You can check /dev directory to see what device that avaible on your computer.
To mount a flashdisk is not difficult. I always do this step to mount a flashdisk:

1. Command below are to find about what type of device of flashdisk that linux read.

#dmesg | grep sda

2. After you get the device, create the mount point

#mkdir /mnt/sda

3. Mount the flashdisk on /mnt/sda

# mount /dev/sda /mnt/sda (asummed that your flashdisk readed as /dev/sda)

For auto mount, you can add some rules on /etc/fstab files..
assumed that your flashdisk are /dev/sda you can add :

/dev/sda /mnt/sda auto user,rw,auto 0 0

easy right? the device not only /dev/sda, may be :

/dev/sda1
/dev/sdb
/dev/sdb1
/dev/sdc
/dev/sdc1
/dev/sdd
/dev/sdd1

and many more...
But the device are usually used are /dev/sda until /dev/sdc1..
On new distro linux, flashdisk can mounted otomaticly..

How to unmount your flashdisk?
Just type
# umount /mnt/sda
# eject /dev/sda

May be some people say that this method not practice,it's all because Linux are distro for people never tired to try, learn, and ask.. So keep learning cause knowledge are power..^^

note: You can use mount utility to mount harddisk device or floppy too..

Make Linux boot disk

Are you ever heard about linux boot disk? Some administrator usually use boot disk as rescue disk. We can use boot disk to repair our linux system, if our system cannot booting. Other use are for rescue data from broken windows or linux system. To make a boot disk are easy, we only need to download zdisk. zdisk are utility to make boot disk in CD or Floppy disk. Few day ago i try to make booting cd and very succesfully.

How to use zdisk? It's very clear on README file that included in their packet.
Cdrom instructions!

# ./zdisk -cd -k path_to_kernel -i path_to_initrd_contents.tgz
-m module_directory

path to kernel are path to your vmlinuz.. usually in /boot directory.
path to initrd contents are path to rescue.tgz. To add more feature, you can insert it into rescue.tgz ( you can extract it first before add more content ). For example ( in README file include), if you want to add bash shell, add bash executable on /bin and then insert the library that needed by bash into /lib. To find what library that bash need, you can type "ldd /bin/bash".
Some note from me, althought you can make booting CD, the size are very limited no more than 20M ( if you know some trick to hack this, please tell me ), until now i still searching to make the CD size more bigger.=)

XGL Installation Script

Do you find a bad result when you install XGL on your distro? Do you tired or confuse about XGL installation? When i'm searching about XGL on uncle google, i find something interested for me. It's an script to install XGL automaticly..=P May be some people will call us scriptkiddie if we use that script, but it's okey for me.. scriptkidie is a process.. Every great hacker never be like that from he or she started learn about komputer. They are learning step by step include from scriptkiddie.^^
The script are listing below.. to use it,just copy and paste it into your text editor and then save as installXGL.sh
to run it you can write
#chmod +x installXGL.sh
#./installXGL.sh
it's otomaticly will install XGL on your distro...

#!/bin/sh

How to Compile or Recompile Kernel 2.6

Firstly for a newbie like me, hearing a "compile kernel" word was very scary. I think compiled the kernel was a difficult work. That's bad think start when i look my computer lab administrator compiled kernel 2.4.18 to kernel 2.4.33, there was many option and choice in kernel menu ( he use make config) if you already tried to compile kernel, you know that 'make config' are kernel configuration with text interface. If we choose just one false option, we must do it again from the start configuration process ( is very bad,right? ^^ i thought it just for an expert people =P) .

Why i compile kernel if it's very scary think ? Some day i want to make my own livecd but unlucky the proses need kernel 2.6.20 and what i see with 'uname -a' ? my kernel are 2.6.13.. very2 bad you know,i must upgrade the kernel to 2.6.20 and i can't do it...!!! In other way i really-really wan to see my livecd cd become succesfull because i want to give it to my girlfriend =P as her birthday gift, an linux with her photo at booting and many funny think like tux games and many more. In other way i also want to make livecd for my faculty Linux Roadshow. ^^

For her i tried to search how to compile kernel or in specific word " how to upgrade my kernel into kernel 2.6.20 " in uncle google. I read many article about compile kernel and i did some experiment with my kernel. After 6 hour's read and read and then try,i succesfully do it.^^
what i do step by step?
1. Download the kernel source ( i download kernel 2.6.20 from http://www.kernel.org )
2. Extrack it in /usr/src directory
3. ln -s kernel-2.6.20 linux
4. cd linux
5. make menuconfig
in this step you must configure your kernel, for easy way just write down what hardware that your computer have in pice of paper and then choose option from kernel menu depend on your paper before. Example: if your processor was Pentium 4,search the option about processor and then select pentium 4 option, motherboard, soundcard same like that.
6. make modules
7. make modules install
8. wait after compile process finished, and then copy the arch/i386/boot/vmlinuz-file to /boot
9. Configure your grub bootloader, add this line on your grub.conf ( on /boot/grub/grub.conf )
title new kernel 2.6.20
root (hd0,(your partition number))
kernel /boot/vmlinuz-2.6.20 ro root=/dev/hda1
10. Restart your computer and then choose new kernel to try it.^^
If everything great, you now have kernel 2.6.20.. u can check it with 'uname -a' utility.
example:
# uname -a
result ==> Linux fecore.ikom 2.6.11-1.1369_FC4 #1 Thu Jun 2 22:55:56 EDT 2005 i686 i686 i386 GNU/Linux
May be i make some mistake, if you find it you can correct me.. I really need it...=)
Now i didn't afraid any more to compiled my kernel.. How about my livecd? My harddisk broken.. and all my data disepear hiks3...=(

Beiryl Window Manager for Fedora Core 6

Fedora core 6,why i choose fecore 6 as my distro ( i always call Fedora Core 6 as fecore, but i don't know why..=p) ? It's all because that distro that i have this time..hehehehe...
actually i want to tryed slackware, but i don't have one.
On default, fecore 6 has an 3D effect but it's not "eye candy" for me, so i try to upgrade it to beiryl.

Beiryl was a 3D window manager that used by Mandriva 2007. When i browse and search in

uncle google i founded that it's very easy to install the beiryl window manager, to install it we can use "yum" utility from fecore 6. Yum utility are utility for install a new software or a packet via repository. In other word we can installed some new software via internet. We musn't download the packet first, the packet will installed directly to our computer. Very fun right?
You can just type
# yum install beiryl-gnome
wait for a minute and then your beiryl will be already installed. I you want an XGL, i got a script for it,maybe i will be posting it in the next post.=)
If you want to try installed XGL via repository, i mean use the yum utility send me the result because i never try it.=P

Add More Accessories on Your Desktop

Perkembangan sistem operasi komputer saat ini bergerak dengan sangat cepat. Hal tersebut bisa dilihat dari munculnya Windows Vista ataupun berbagai distro Linux seperti Mandriva 2007, Fedora Core 6, Slackware 11 dan masih banyak lagi. Fitur-fitur yang disediakan oleh masing-masing produk untuk memanjakan pengguna juga semakin beragam macamnya.
Jika dilihat dari sisi tampilan desktopnya, telah muncul inovasi desktop 3 dimensi dengan disertai efek-efek yang menarik dan beragam. Selain efek 3 dimensi, ada asesoris tambahan yang menarik untuk desktop anda. Bagi pengguna Microsoft Windows dan Mac OS X tersedia Yahoo!Widget, sedangkan untuk pengguna Linux tersedia gDesklet dan Super Karamba.
gDesklet dan Super Karamba sebenarnya mempunyai tampilan yang hampir sama menariknya. Yang membedakannya hanya terletak pada Window Managernya. Perlu diketahui, di dalam Linux terdapat beberapa macam Window Manager yang bisa dipilih untuk berganti suasana tampilan. Window Manager tersebut antara lain Gnome, KDE, Fluxbox, IceWM, Blackbox, Xfce, dan Fvwm.
Super Karamba diperuntukkan bagi pengguna Window Manager KDE, sedangkan gDesklet diperubtukkan bagi pengguna Window Manager Gnome. Namun tidak menutup kemungkinan gDesklet dapat dijalankan pada Window Manager KDE dan Xfce.

gDesklet merupakan aplikasi di belakang layar yang menyediakan arsitektur tambahan untuk desktop dalam bentuk applet. Applet-applet kecil yang berjalan dalam gDesklet disebut dengan desklet. gDesklet dibuat oleh Martin Grimme, Christian Meyer, dan Jesse Andrews. Paket gDesklet beserta koleksi desklet-deskletnya dapat di download di http://gdesklets.gnomedesktop.org.
Tujuan utama applet diletakkan pada desktop adalah agar user lebih cepat memperoleh informasi tanpa harus meninggalkan aktifitasnya pada saat itu. Namun pada perkembangannya saat ini, sebuah desktop applet juga digunakan untuk mempercantik tampilan pada desktop anda.
Banyak desklet-desklet yang tersedia di website gDesklets, beberapa diantaranya adalah tampilan jam, calendar, ramalan cuaca, RSS feed aggregators, control untuk aplikasi lain (seperti Media Pelayer dan Gaim), toolbar animasi, system monitor, status meters, icon bars, news tickers, pemakaian CPU, pemakaian RAM, pemakaian Harddisk, CPU temperatur,dan banyak lagi tampilan lain yang sangat menarik untuk desktop serta dapat disesuai dengan keinginan anda.
Tampilan desklet pada desktop benar-benar tampak menyatu dengan wallpaper , tidak dapat dibedakan antara desklet atau sekedar wallpaper,seakan-akan itu bukan sebuah aplikasi yang berjalan pada desktop anda. Setelah dijalankan, desklet akan selalu di desktop anda dan tinggal digunakan ketika anda membutuhkannya. Saat tidak digunakan, desklet akan menjadi eye candy yang sangat menarik, desktop anda akan tampil seperti desktop komputer dengan berbagai aplikasi berteknologi tinggi yang sering muncul di film-film fiksi ilmiah.
Anda bebas berkreasi untuk menampilkan apa saja yang ingin anda tampilkan. Anda tidak harus mendownload desklet-desklet yang ada diinternet karena kita dapat membuat desklet kita sendiri dengan mudah. Desklet yang ada sekarang dibuat dengan ADL (Applet Description Language). ADL adalah bahasa untuk mendeskripsikan user interface pada gDesklets ,ADL berbasis pada bahasa XML yang di desain flexsibel dan sangat mudah dipelajari. Hanya dengan 11 baris ,anda sudah dapat menampilkan desklet berupa jam atau calendar buatan anda sendiri dan tidak kalah bagusnya dari desklet-desklet diinternet. Bila anda cukup kreatif, anda dapat membuat desklet multimedia sendiri dengan tampilan-tampilan menarik.
Bagi pengguna Windows dan Mac OS yang berminat menggunakan Yahoo! Widget dengan fitur seperti gDesklet, dapat mengunjungi http://widgets.yahoo.com untuk mengunduh program instalasi dan koleksi Widget. Koleksi yang tersedia antara lain tampilan untuk scrolling translation,info bar,CPU tracker,system gauge,remote desktop,web cam,dan masih banyak lagi koleksi lainnya dengan fitur-fitur yang cukup menarik.

Looking Glass 3D desktop...

Looking Glass atau yang biasa disebut lg3d ,adalah 3d desktop buatan dari sun microsystem..
Dilihat dari themenya yang seperti glass dan effect-effectnya,aku menganggap desktop ini mempunyai tampilan paling keren^^. Selain tampilan tersebut,ada keistimewaan lain yaitu selain aplikasi bawaan dari desktop tersebut,kita juga dapat menjalankan aplikasi standart kita dengan theme menyerupai glass tersebut tanpa harus menyetting apapun juga.
Cara instalasi dari lg3d ini pun cukup mudah,hanya perlu sekitar 5-10 menit saja..:p
Pertama kita harus mendownload packet binarynya dari web sun.. packet-packetnya tersedia untuk windows maupun linux,jadi pengguna windows pun dapat menggunakan desktop tersebut.=)
Cara instalasinya adalah sbb:

Copykan packetnya ke directory /usr/share
#cp lg3d.x.x.x.bin /usr/share
masuk ke direktory /usr/share
#cd /usr/share
extract packet tersebut
#./lg3d.x.x.x.bin
Anda akan mendapat directory lg3d,masuklah ke directory tersebut dan carilah directory bin
#cd lg3d/bin
jalankan executable dari lg3d tsb.. Ada 4 seh executablenya (postinstall,lg3d-dev,lg3d-app,dan lg3d-app-full) tetapi
kita cukup menjalankan postinstall dan lg3d-app-full saja, postinstall adalah script untuk menginstall lg3d pada session sedangkan lg3d-app-full untuk menjalankan desktop lg3dnya..
#./postinstall
#./lg3d-app-full
mudah bukan? dengan langkah-langkah sederhana seperti diatas ,kita dapat memiliki desktop yang menarik dan keren.. Sayangnya desktop ini masih sangat berat,jadi yah..,hanya dapat untuk pamer saja m temen-temen..^^
mungkin setelah dikembangkan lagi (proyek lg3d adalah proyek open source yang dikembangkan bersama-sama, tidak hanya oleh sun saja) dapat lebih ringan ,sehingga dapat dijadika home desktop kita..=)

3D desktop

beberapa minggu ini aku lagi coba-coba tentang 3D desktop di Linux, ternyata cukup menarik sih.. banyak hal yang bisa digali dan dipelajari. Ni lagi mo coba-coba upgrade lg3d dari sun,biz tampilannya keren seh ^^
kalo bisa seh yang bersifat demo mo aku ilangin n diganti aplikasi yang aku suka..
sementara ini aku udah coba 3ddesktop,lg3d,m beryl , kalo untuk desktop sehari-hari, beryl dan 3ddesktop mungkin pilihan yang paling baex sekarang ini,bz 3D tersebut tidak terlalu berat. kl lg3d kayanya cocok untuk pamer..he3..

Buat 3Ddesktop,instalasinya mudah banget. yang perlu disiapkan cuma dependensis nya yaitu imlib2 dan imlib2-devel..
proses installnya
#rpm -ivh imlib2.X.X.X.rpm
#rpm -ivh imlib2-devel.x.x.x.rpm
#tar -zxvf 3ddesktop.x.x.x.tar.gz
#cd 3ddesktop.x.x.x
#./configure
#make
#make install
biz itu tinggal jalanin aja daemonnya
#3ddeskd --acquire
n trakhir jalanin 3D nya..
#3ddesk --mode=

yach,selesai deh... yang diatas tuh gambar dari salah satu mode,kalo ga salah seh mode normalnya.. ^^
