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.

Before I use pop3 for remote retriving e-mail I used
imap, remote tel net 143 port is OK, but due to Mozilla
browser's own problem, it did not work; however, my receving
rmail from the server itself was fine; now I activated my pop3 server,
I was happy that I can retrive email from the remote server,
unfortunately it was indeed a problem, since I can only
receive email from the same domain (my own domain), not from
any other email account from outside? Even after I disable
my imap server, it sill does not work, why?
The strange thing is in iptables, I opened both 25 and 110 ports,
they are both remotely telnetable, and I was happy at that time.
Now after I activate my pop3 service for remote email retrieveing,
I found I could not receive email from out side, after
did an netstat -nlp, I found my port 25 is still open as
110, but remotly and locally telnet 25 port failed, what succeeds
is only telnet 127.0.0.1
# Duron 950 uilleann /etc/hosts file: This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server. Just add the names, addresses
# and any aliases to this file...

127.0.0.1 uilleann uilleann.phils localhost
192.168.0.1 tinwhistle tinwhistle.phils
192.168.0.2 uilleann uilleann.phils
I ran service restart xinetd, looks like remote telnet still fails
My problem is I use sendmail, and it requires me to open
25 port at 127.0.0.1 only, while I also use pop3, and it require
me to open my IP's 25 port, so I revised my iptable to open
25 port, will that have an impact?
dnl This is the macro config file used to generate sendmail.cf
dnl file. If you modify this file you will have to regenerate
dnl sendmail.cf by running this macro config through the m4
dnl m4 /home/fancy/Documents/sendmail.mc > /etc/sendmail.cf <--Change to your path
dnl You will need to have the sendmail-cf RPM installed for this
dnl to work, if you use an rpm build of sendmail
dnl If you compile sendmail from a tarball, use the include above.
dnl In this setup, you should create the file as cf/cf/config.mc
dnl (in the sendmail source tree: eg. /usr/src/sendmail-8.11.6/cf/cf
dnl Now give the command "sh Build config.cf". Now copy the file
dnl config.cf as /etc/mail/sendmail.cf (please backup first!)
dnl If you are using the RPM build of sendmail, use the
dnl include statement given below instead
define(`SMART_HOST', `smtp.yourisp.com') <--Change this
MASQUERADE_AS(`yourisp.com') <--Change this
FEATURE(`mailertable',`hash -o /etc/mail/mailertable')
FEATURE(`virtusertable',`hash -o /etc/mail/virtusertable')
