It appears to have been a problem with upgrading to libc-5.3.12-24, when I
went back, and "rpm -ivh --force libc-5.3.12-18.i386.rpm
libc-5.3.12-18.2.i386.rpm"
and then "rpm -ivh --force libc-5.3.12-24.i386.rpm" it worked correctly.
It appears that jumping to libc-5.3.12-24 without -18* failed to create the
file /etc/nsswitch.conf which is needed to know how to resolve hostnames.
