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 been put in charge of installing a new SMTP server. so, i have decided to broaden myself and get into linux... here is what i have and here is the problem. i have ubuntu server installed (honestly i'm not too sure which flavor...i want to say gutsy gibbon). also, ubuntu has been installed as a virtual machine using VMWARE 1.5. to help a hack like me, i installed webmin because i am not too comfortable at the command line. next i installed and started postfix. went great. just for the fun of it, i sent some mail from the webmin/postfix console using one of the built-in user mailboxes...mail delivered perfectly. here is my problem. when i try to send mail from a simple mail client, the client connects to the server, but times out trying to send. i have tried to disable all autentication...this server is on my LAN behind firewalls, so i have no need for authentication to send mail. also, i have checked the boxes to accept all smtp mail clients and disabled all encryption. any ideas? thanks - shagcarpet
thanks for the reply. i can see that what you say is probably the issue. when i telnet to the linux box, "telnet 10.19.6.47 25", it appears to connect, but comes back with a black screen with the cursosr flashing... when i type, the cursor moves but no characters are displayed. when i hit enter the cursor jumps to the next line. have i hosed the config? here is the optput of "postconf -n", run from the command shell in webmin.
Thanks for the reply...
both (a) and (b) have the same results.
i assume i connect each way, i see just a black screen with the cursor flashing...if I type anything, the cursor moves but nothing is displayed. when i hit enter it jumps to the next line.
also...when i try to send mail thru it (using windows mail), the client says connected for about a minute, then comes back with a timeout error.

yeah...something definitely doesn't seem right. i have limited experience with linux, but many years of windows/server experience...i've never seen a telnet session do stuff like this.
i ran the localhost test on the guest OS (which is Ubuntu)...native host is Windows 2003. test from another host was run from another windows 2003 server on same LAN segment. again, both have the same results. is a reload in order?
