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.

I am extremely thankful to you for your suggestions. Yes, SSH worked !! I could enter (login) with SSH. However, I am curious to know as to why is 'telnet' disabled? I see that 'xinetd' is running, but it is not allowing for telnet connections. Why is this? Kindly inform.
However, I have not yet achieved what I wanted to achieve. Entering the system using telnet was only the first step.
I have 2 PCs at my home. One is running Redhat 9 and other one is running Solaris 10 (for x86). I wanted to network these two. The linux box also has another interface through which I can browse the net. Now, I wanted to enter this linux box from the solaris box ( which I could do it now using SSH ). From this SSH session, I would like to open the browser (mozilla) using the command 'mozilla', but it says some display problem. I also tried to issue the command 'xterm' but even that gave the same problem.
The detailed steps and the error are as follows:
(a) I started SSH from my solaris box and logged into the linux box - Successful.
(b) I issued the command: xterm ( this means the xterm of the linux box is expected to run and I would like to see the xterm window in my solaris box ) - Failure.
Xlib: connection to "172.27.248.20:0.0" refused by server
Xlib: No protocol specified
xterm Xt error: Can't open display: 172.27.248.20:0.0
NOTE: The IP address "172.27.248.20" is that of the solaris box. In other words, I have set my display in the solaris box using the command: export DISPLAY=172.27.248.20:0.0
[I run bash shell].
(c) I also issued the command 'xhost +' in the linux box, but even this did not help.
What could be the problem here? How do I rectify it?
Telnet is not considered safe any more, as the user name and password are passed "in the clear" to the server. Most distributions do not include it (telnet) by default. You have to go back and specifically install and configure it. SSH is standard for most distros...
Of course, if both machines are sitting side-by-side then the man in the middle attack becomes laughable, because the man would be sitting right beside you
