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 just installed Fedora 5 and plan to use it to run an Apache web server in my home. After the install was done I started Apache and opened a browser page. I typed http://192.168.2.106 and saw the default test page so I figured everything was setup OK. I tried doing the same from another computer on my lan but got a page not found. I also tried it from outside the lan by typing www.compunerdsdev.com and http://compunerdsdev.com, but got the same result. I checked the settings in ZoneEdit and the web server should be live, and I have port 80 forwarded in my router. I also found out that my ISP doesn't block port 80. I was able to ping the server from my XP pro computer. I even set SElinux to permit and still nothing. Any suggestions would be much appreciated.
Most probably your firewall in the Webserver is setup so as to deny any connections from outside the local machine. Please check if you have any rules in your IPTABLES or TCP Wrappers (/etc/host.deny & /etc/host.allow).
Also it would be much appreciated if you could paste your 'iptables -L' output. Think we can solve it...
and it should do it.
As for why ACCEPT all -- anywhere anywhere in the first line does not work. I am not sure. But it seems that the last line of reject all did his work. I tried google for a while but did not find any good explaination. Maybe, someone else can share his knowledge here.
According to documentation of iptables, the rule are parsed one by one in the order of the rule set. If there were a match like ACCEPT, it is accpet and terminated. Clearly, this does not happen here.
