LinuxQuestions.org - LVS - VIP Seems to be NOT Responding!

Hello:

It seems that VIP 65.103.190.107 on my LVS is NOT responding!

I have setup a simple LVS. Two Virtual servers (vs1.tib.com & vs2.tib.com) and one Real Server (rs1.tib.com) on CentOS 5.3. Now when I trying to display a test Web site (on rs1), the request times out.

On vs1 there is nothing in the logs. No error message. Just nothing.

From VS1, I can display any outside (http://www.msn.com) but can't display internal web (http://www.tib.com) pages.

I have a hunch that the virtual setting for HTTP in piranha-gui is not correct. But what? After two days, I need direction.

This may help; I open the piranha-gui to look & see if there was any error. After I closed the piranha-gui screen, Inoticed the following errors in /var/log/piranha/piranha-gui:

( There are 10-15 more similar error messages........ )

Is it causing the problem I am encountering? What is this error? Is it supposed to be there?
