You never said what in your etc/host file
My etc/host file looks like this for lfs.
# Begin /etc/hosts (network card version)
127.0.0.1 localhost
192.168.0.5 chevy.homenetwork chevy
# End /etc/hosts (network card version)
And like this for debian 3.1
127.0.0.1 localhost.localdomain localhost
192.168.0.5 debian.hom debian
if this does not work go to
www.google.com/linux and try 'networking howto'
good luck
