Seconded that. If your /etc/hosts is empty then add something like: localhost.localdomain localhost youserver.yourdomain yourserver

You may ad more lines including other servers in format "IP
ServerName.Server.Domain" One IP may have more than one name. Of
course starting bind also is a help as by default it is set for cahing
name server.
