Cara Format USB Flashdisk Ubuntu via Terminal

Berikut cara memformat USB Flasdisk via Terminal:

1. Tentukan letak device USB Flashdisk Anda.

Setelah menancapkan USB Flashdisk anda lakukan perintah berikut,

root@spydeeyk-r00m:~# fdisk -l

root@spydeeyk-r00m:~#

USB Flasdisk saya berada di /dev/sdb1, letak device usb flashdisk anda bisa saja berbeda dengan saya.

2. Unmount USB Flashdisk Sebelum diformat.

root@spydeeyk-r00m:~# umount /dev/sdb1

3. Format USB Flashdisk.

mkfs.vfat -n 'Label' -I device

Contoh:

root@spydeeyk-r00m:~# mkfs.vfat -n 'spydeeyk' -I /dev/sdb1

Selamat Mencoba.

Cara Menghapus Kernel Lama di Grub Ubuntu

Ada dua cara untuk menghapus kernel lama di grub ubuntu (se-tahu saya :D):

1. Via Synaptic Package Manager
Akses Synaptic Manager:
System --> Administration --> Synaptic Package Manager
Search dengan keyword 'kernel', lalu hapus kernel lama yg anda inginkan. Tapi, penting untuk diingat!, jangan salah hapus kernel yang sedang anda gunakan.. hehehe..

Untuk mengetahui kernel yang sedang digunakan, ketikkan perintah:
# uname -a 

Contoh:

root@spydeeyk-r00m:~# uname -a
Linux spydeeyk-r00m 2.6.32-30-generic #59-Ubuntu SMP Tue Mar 1 21:30:21 UTC 2011 i686 GNU/Linux

Nah, pada contoh diatas kernel yang saya gunakan 2.6.32-30-generic.

Oh ya, setelah kernel lama dihapus alias diremove via synaptic package manager lakukan pula perintah:
# update-grub2

2. Via Command Terminal
Pertama kita cari tahu dahulu kernel-kernel yang terinstall di system kita dengan perintah:
root@spydeeyk-r00m:~# aptitude search linux-image-2.6 | grep "i "


Contoh:

root@spydeeyk-r00m:~# aptitude search linux-image-2.6 | grep "i "
i   linux-image-2.6.32-21-generic   - Linux kernel image for version 2.6.32 on x
i   linux-image-2.6.32-22-generic   - Linux kernel image for version 2.6.32 on x
i   linux-image-2.6.32-24-generic   - Linux kernel image for version 2.6.32 on x
i   linux-image-2.6.32-29-generic   - Linux kernel image for version 2.6.32 on x
i   linux-image-2.6.32-30-generic   - Linux kernel image for version 2.6.32 on x

Setelah mengetahui kernel-kernel yang terinstall, sekarang kita bisa remove kernel yang kita inginkan (ingat jangan remove kernel yang sedang dipakai, ok? :D )

Contoh:

root@spydeeyk-r00m:~# aptitude purge linux-image-2.6.32-21-generic

Bagi saya ada baiknya disisakan 2 kernel.. kernel yang sedang dipakai dan sebelumnya, buat jaga-jaga aja.. :D

How to Reset Windows Password Using Ubuntu - chntpw

Berikut bagaimana cara untuk mereset password windows (XP, Vista, Windows 7) menggunakan Ubuntu dan chntpw.

Ada dua kemungkinan dalam penggunaan Ubuntu. Pertama, bisa jadi di komputer atau laptop Anda sudah terdapat sistem operasi ubuntunya (dual boot), maka anda dapat langsung menginstall packet chntpw. Kedua, jika anda tidak menggunakan dual boot, windows dan Ubuntu, Anda dapat mengunduh Ubuntu, dan membuat Bootable Ubuntu Usb Flash Drive (live ubuntu via flashdisk). Dan satu lagi, anda perlu terkoneksi ke internet untuk dapat menginstall paket menggunakan perintah apt-get install :) .

Sekarang kita mulai mereset password windows menggunakan Ubuntu dan chntpw.
