My friend using ubuntu 9.04 and he lost the root password, we can’t using the recovery mode because protected by root password.

So i am searching on google then i have the answer.

First you must restart, then you can see, like on the picture.
1. Press enter on Your OS, then search ro quit splash
ro quit splash used for usplash
2. Change ro quit splash with single init=/bin/bash
This syntax will lead us to single init mode
3. Press enter Then press Ctrl+X for reboot
4. Now you on single init mode
5. After the loading finish, type this syntax
sudo mount -o remount rw /
function of this command is mount the your root partition.
5. you can see all user on your system with this syntax
ls /home
6. Lets change your root password or your user password with command
passwd “user login”
ok…
and you can login with your username and your new password.

When you blocked by proxy, but your soul is online soul, it is complicated.

Ok change your mac, but you must know mac another computer, maybe you can using wireshark or other to know mac adress another, but when you login on proxy can’t double mac address.. e,….mm, not only that, change your mac can protect your computer, i am sure if you know.. ok check it out.  8-o

open your console,

1. Show your mac
#ifconfig -a | grep HWaddr

2. Down your NIC , up to you eth0, eth1 or other.
# ifconfig eth0 down

3. Change your mac with syntax hw ether..lets go
# ifconfig eth0 hw ether 00:aa:48:yy:zz:30

4.  Successfull, are’nt u?, up the NIC again
# ifconfig eth0 up

5.  Show your mac now ..jreng…is change..!!!
# ifconfig eth0 |grep HWaddr
trust me it is work..if failed u can contact me..

Not rare on my ear if you using dual boot or triple boot, moreover maybe multiboot..  :lol:
ok if you install windows after you have Linux on your PC, maybe you have problem, right,…. lose your GRUB.
ok fix it.

1. Boot with your Live CD Ubuntu 10.04 LTS
before it setting BIOS for booting via CD room

2. After your Ubuntu Live work, open your console and using root with sudo su or other.

3. Type this command
# sudo fdisk -l
can you see position your Ubuntu Partition?ok.

4. Mount the partition containing the Ubuntu installation.
ex:
Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       58336   468583888+  83  Linux
/dev/sda2           58337       60801    19800112+   5  Extended
/dev/sda5           58337       60801    19800081   82  Linux swap / Solaris
#sudo mount  /dev/sda1  /mnt

5. install grub
#sudo grub-install –root-directory=/mnt/ /dev/sda

if no error you will get message
install completed with no errors.

6. Reboot
take your CD Live..
