you were absolutely right,  the problem  was  eth0 was not seen by 
udev.  

from LFS SVN-20071223/chapter07/network.html (section 7.13)  I ran
/lib/udev/write_net_rules all_interfaces

and then did
cat /etc/udev/rules.d/70-persistent-net.rules

I discovered that   the net device was seen as eth1.  I changed it to 
eth0 and it is now working.

thanks  for all your help.
