Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

If you don't know about telnet, don't use it. Telnet is the predecessor to SSH and is not enabled on most new systems for a good reason. EVERYTHING over telnet is sent "in the clear" (that is, unencrypted). SSH has all the functionality of telnet, and then some. If you really want to use telnet after all this, you'll need to install the telnet server package. I'm not sure which that is under Fedora, but I'm sure a quick search through an RPM site will find it.
However i can only login as a normal user and it wouldn't allow me to
login as root
The telnet file of the machine read as :
# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = no
Do i have to edit the file so as to be able to login as root?
