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.

from my solaris box I can ping my linux box but I can't get logged into the linux box via rlogin or telnet. With telnet, it brings up the log-in dialog but even when I try to login as root it gives me a 'Login incorrect' message. With ftp and rlogin my connections are refused. I have amended the telnet file in xinetd.d to disable=no.
Ok, are these services tcp wrapped? What does your inetd.conf file look like? Have you run a port scan to see if the ports are listening? What distro are you using? Ftp server? Why do I have more questions than you do?
incidentally, you may want to consider using ssh instead of telnet.
Sorry, I'm on my second cup of mate -- I'll try to take it easy.
Let's start with your distro and kernel version. You should now the distro straight off. For the kernel version, type 'uname -r'
I am curious to see if necessary ports are open. Nmap may already be on your machine. Simply type (as root) 'nmap localhost' Post the results. If you get a 'command not found' error, you need to get it and install it -- it's an invaluable security tool.
Just for fun, try this from your Solaris box: 'ssh IpAddressOfLinBox' and see if you can log in with a user account.
