FC3 install - no network

[Ashley M. Kirchner]

    I just did a fresh installation of FC3 on a system that used to run 
RH9.  Installation went fine, system came up ... except the network 
won't work.  Now, I checked all the files _I think_ needs to be checked, 
and they all appear to be okay:  /etc/sysconfig/network, 
/etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-lo

    All the values and options are the same as what they were on the old 
setup (I made a backup of those files, so I'm comparing them now.)  Yet, 
the network simply won't work.  Checking 'ifconfig' everything appears 
to be fine.  Running 'route' on the other hand hangs for a bit before 
finally giving me the last line:

    # route
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    
Use Iface
    206.168.220.48  *               255.255.255.248 U     0      
0        0 eth0
    [ ... here it hangs for a while before the last line ... ]
    default         206.168.220.49  0.0.0.0         UG    0      
0        0 eth0


    Now, on any of my other systems (still running either RH7.3/9 or 
FC1, when I run 'route', it also displays a line for the loopback.  It's 
not showing up on this machine (though the loopback does show up in 
ifconfig.)  So, someone please shine some light here...what have I 
forgotten?  Why in the world would it not work if everything is setup 
the same?
