dns problem in apache

Hi,

I am running scientific linux (which is clone of red hat linux) on virtual machine that is virtual box.

I tried to start the apache but I got the following message.
starting httpd: httpd: arp_sockaddr_info_get() failed for scientific-linux
httpd: could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

and when I try to access the server from my host computer (the host of the guest OS that run in the virtual box) I get a message that it could not reach the server.

How can I solve it and allow the httpd server to consider its IP address as it server name?

first google hit

thanks the problem is that my system is not based on debian but on red hat.

What was your google search if I may ask?
