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 have install Redhat 9 's linux mail server(sendmail). It could send and receive mail from localhost.localdomain. But it can't recongnize it's own domain name (hitech.com).
I have set the domain name in /etc/resolv.conf like this
The host name is "machine1". When I ping "machine1.hitech.com" it did reply. But when I send mail to "email@example.com" it just won't able to deliver. It only work if I send mail to "root". What am I missing?
If you want to know whether ur dns config fine or not, simply type in the prompt (your linux box):
nslookup (hit enter)
server 188.8.131.52 ( your dns server's IP) (hit enter)
linuxquestions.org (hit enter)
if you got answer like this :
server :your dns server name
address : your dns server ip
> server 184.108.40.206 (my ip)
Default server: 220.127.116.11
;; connection timed out; no servers could be reached
I wonder my domain name is valid or not, it's naming convention is like this <myname>.connect.to,
is that just involve the two files <mydomain name>.dns and <mydomain name>.rev in /var/named will be fine ?
