Sometimes some people forget their root password on their Linux machine. And not recommended to install back the Linux since so many configuration have done during that period time. Now, we can retrieve the password as long as we have physical access to the Linux machine. There are 2 ways to solve this problem.

1st way
Reboot your Linux machine
Get into “grub” menu then press “e”
Go to your default kernel then press “e” again
Then go to grub prompt grub> default_kernel single <– type “single” at the end of your kernel. We are entering single mode.
Then it will appear as sh-3.00#
Then type “passwd” or edit /etc/passwd

2nd way
Reboot your Linux machine
Boot from 1st CD of your distro
Get into the “Rescue Mode”
Follow the instruction
We get into prompt again sh-3.00#
Type “sh-3.00# chroot /mnt/sysimage”
Then type passwd or anything you want

Congratulations you have your root password back. Don’t forget about your root password again in the future

Tak terasa sudah hampir setahun menggunakan Ubuntu 7.04 feisty fawn di laptop ini. Sudah banyak pekerjaan yang diselesaikan menggunakan laptop acer tersebut. Dan tentu saja sudah banyak file di direktory /home yang sangat berharga. Baik itu file konfigurasi, photo-2 kenangan ataupun iso linux dengan berbagai macam distro.

Dengan begitu banyak file di direktori /home sangat rentan kalau sebelumnya direktori tersebut berada menjadi 1 di direktori root. Karena kalau kebiasaan ngoprek timbul, maka bisa-2 file di direktori /home akan tertimpa -overwrite- dan itu menjadi sebuah yang sangat menyedihkan. Waktu bergulir, banyak panggilan sana-sini dan akhirnya rencana untuk mengubah penempatan direktori /home berdiri sendiri kesampain juga saat ubuntu Hardy Heron 8.04 release.

Tak lupa, seperti janji sebelumnya untuk si Hardy ini akan dihadiahi sekeping SODIMM RAM 512 Mb. Sehingga total RAM yang dimiliki laptop acer ini menjadi grand total 1Gb. Sebuah hal yang sangat mewah untuk saya pribadi, dan juga si acer laptop karena akirnya dapat ‘bernafas’ saat dibebani dengan berbagai macam task ataupun job saat remote ataupun konfigurasi server ataupun mikrotik.
