General Notes

This is an Unofficial Ubuntu 5.04 Starter Guide. It is not associated with Ubuntu and Canonical Ltd.
Guide is tested on a full installation of the Ubuntu 5.04 x86 Install CD (Hoary Hedgehog)
If you see black box, means you have to execute the commands in Terminal mode (Applications -> System Tools -> Terminal)
To reduce typo mistakes, copy and paste the commands into Terminal mode (right click on the commands -> "Copy" or "Paste")
"sudo" means superuser do. "sudo" will prompt for "Password:". Please specify user password
If you are tired of typing "sudo" all the time, switch to root user by issuing "sudo -s -H" followed by user password
If you are tired of typing "apt-get" all the time, Read How to apt-get the easy way (Synaptic)?
"apt-get" and "wget" requires Internet connection to install/update/download programs
To download file, right click on the link -> Select "Save Link As..." -> Make sure file name and extension are correct
Some multimedia applications may not load/produce sound, Read How to configure sound to work properly in GNOME?
For any feedbacks, suggestions, discussions and bugs report to the author, please post comments: Here
May the "humanity to others" spirit be with you always...

Ensure a password is set for BIOS
1. To prevent trespassers from changing the BIOS boot-up sequence
Ensure computer is located at a secured place
1. To prevent trespassers from removing computer's hard drive which allows them to destroy/browse/share the entire hard drive from a different computer
2. To prevent trespassers from removing computer's on-board battery which resets the BIOS password
Ensure passwords used on the system cannot be easily guessed
1. To prevent trespassers from cracking password file using brute force attacks (e.g. John the Ripper)
2. Create password with minimum length of 8 characters
3. Create password with mixture of characters/numbers, and upper/lower case
Ensure interactive editing control for GRUB menu is disabled
