Poking around further (flailing) :

bigbird ~/tmp: $sudo /sbin/ip link list
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 100
    link/ether 00:60:08:aa:0a:94 brd ff:ff:ff:ff:ff:ff
4: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP> mtu 1524 qdisc pfifo_fast qlen 3
    link/ppp
bigbird ~/tmp: $

Eth0 does not say ",UP".

bigbird ~/tmp: $sudo /sbin/ifup eth0
/sbin/ifup: configuration for eth0 not found.
Usage: ifup <device name>
bigbird ~/tmp: $

There's no/etc/sysconfig/resolve.conf file

bigbird /etc/sysconfig: $sudo /sbin/ip address show
Password:
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 100
    link/ether 00:60:08:aa:0a:94 brd ff:ff:ff:ff:ff:ff
4: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP> mtu 1524 qdisc pfifo_fast qlen 3
    link/ppp
    inet 208.28.179.147 peer 208.28.179.107/32 scope global ppp0
bigbird /etc/sysconfig: $

Inet shows up because I'm online using dialup -  ppp0 shows ",UP"

bigbird /etc/sysconfig: $sudo /sbin/ip route show
Password:
208.28.179.107 dev ppp0  proto kernel  scope link  src 208.28.179.147
127.0.0.0/8 dev lo  scope link
default via 208.28.179.107 dev ppp0
bigbird /etc/sysconfig: $

It's all about dialup.  etho is just not there.
