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 linux box with two ip addresses on one NIC. One is a virtual ip I need for my LVS cluster and one is the actual computers ip address. I have been unable to get my load balancer to work so for the time being I have setup a webserver on the box. I have setup a DNS with two totally different domain names. One points at one ipaddress and the other domain points at the virtual ip. I am able to view the one domain while the other domain on the virtual ip gets back an error on my browser when I try to view it.
I can telnet into the virtual ip on port 80. I also called RedHat cause we have a support package, and he has told me that I have my DNS setup correctly and my webserver is setup correctly as well and after that he basically said "I don't know what the problem is". I can also ping both domains and interfaces. I also did a tcpdump on port 80 of the interfaces and on the one ip I see the requests but the virtual shows nothing when I try to access the other domain.
Moved: More suitable in our Networking forum. Also you should use better thread titles as well that actually describe your problem. It makes it easier for members searching or browsing to know what your thread is about. Also putting 'desperate' help will at times detract users from reading, as it comes off as being rude as most come here in their spare time on this free forum. Regards and hopefully by moving to a more appropiate forum, you get the answer to your question.
When I monitored the one ip that is normally working and did a web request it went through ok but now when I did the same with the virtual ip and did a web request it shows the src with a port opened above 1024 to the destination of my dns domain on port 80 but there does not seem to be a return on the request. What could be causing this???
