1.    D:\> CD \ dosutils
2.    D:\ dosutils>rawrite
3.    Enter disk image filename : ..\images\boot.img
4.    enter target disk drive :  a:
5.    Please insert a formatted disk into drive a: and press enter.
6.    D:\ dosutils>

INSTALLATION METHODS :-

·         Local CD- ROM : If you have a CD-ROM containing the red hat Linux software and a boot disk then you can install red hat Linux with this method. Your machine needs to have a CD-ROM drive and floppy drive.
·         NFS image : This method is used if you want to install red hat Linux over a network from a CD-ROM that supports the network file system. You should know the NFS server’s IP address.
·         FTP : This method is used if you want to install Linux from a FTP server. You must have the start up disk and the supplemental disk for FTP installation.

INSTALLATION STEPS :-


·         Boot from boot disk or CD-ROM
·         Choose language and installation media
·         Set up partitions, configure swap and file systems
·         Select packages to install
·         Set up mouse, networking and printer
·         Set root Password and configure authentication
·         Create boot disk
·         Set up LILO
·         Configure X-Windows
·         Reboot
·         After the system is booted the installation program will take over and ask you a number of questions. It will then install Red hat Linux.
·         After installing, which may take anywhere between 5 minutes and 1 hour. It’ll also try to set up your mouse, monitor, networking and printer.
·         When installation is finished you are asked  for a root password after that the installation will offer to create a boot disk and offer to install LILO for you.
·         It’ll then configure your X-Windows environment
·         The last step the installation program will do is rebooting so your Linux system will boot all by itself.

INSTALLATION OVER THE NETWORK :-


REQUIREMENT :- 2 floppies , dump on server and IP of server

STEPS :-

·         Boot the system from 1st floppy. It’ll open the installation Wizard
·         Insert the 2nd floppy which helps to communicate with the server and install the Linux from the dump on the server. Rest of the steps are same as that of the previous installation steps.

COMMANDS FOR USERS AND GROUPS :-

# useradd name : to add a user
# passwd name : password for new user
# groupadd : to create a new group
# gpasswd name : password for new group
