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 a machine at home that was acting as my email server, web server and internet firewall. It was running Fedora Core 4. I saved all my data, wiped the system and installed Fedora 7 on this machine today. I updated all the software with yum, installed httpd, dovecot, postfix and edited all my config files. I'm having the following problems and I hope someone (or several someones) can help me track them down...
1) System startup. I have configured eth0 with dhcp - connected to the internet. I configured eth1 with a static IP address on my internal home network. When the system starts, eth0 is started but eth1 is not, and the IP address it has is 169.254.x.x - which I think is set in the ifup-eth script in /etc/sysconfig/network-scripts. If I deactivate and re-activate eth1 it comes up configured correctly. Any idea why? Or what I need to do to get it to start properly upon a reboot?
2) I installed dovecot (IMAP server) and postfix and configured them as I did on FC4. They start properly and I am receiving mail from the internet.
However, when I run evolution on one of the other machines in my network, I get an error that says 'Can't connect to mail.aikisoft.com - no route to host'. From that machine, I can ssh to mail.aikisoft.com without any problem. I can also telnet to port 25 and issue a helo command. I can ping that hostname. What is evolution looking for? Why can't it locate the imap server?
3) I wrote down my firewall rules - but I use webmin to create them. The outgoing rule was a masquerade - anything coming from inside the house gets sent out to the internet... But now I can't figure out how to create that masquerade rule - can someone familiar with webmin point me in the right direction? I did this a couple of years ago and have not touched it since...
I'm sending this message from the newly built machine, so networking is basically running - firefox works and lets me access the internet, and mail is being added to my incoming mail box. So it looks like just a couple of small configuration problems stand between me and getting the system back up and running properly. Any help or pointers would be greatly appreciated. I'll be looking for online documentation to see if I can track these down myself too...
I think I found the Masquerade problem - I was looking at the output chain not the postprocessing output chain. I think that should now be ok.
Still have the problems with device startup and email tho...
Well, it looks like the problem with the imap server is related to the ethernet configuration problem. The internal ethernet (static IP) configuration did not specify a gateway, which was causing the IP reset to occur. When I added the default gateway, the static IP configured itself properly, and Evolution started seeing the mail server from my internal machine. So far so good. The only real problem I seem to have left is that the internet facing interface, which uses dhcp does not seem to get set
correctly on a reboot. I have to manually disable and re-enable that interface after the system boots and then it gets a correct address.
Any idea why that would be??
