All,

Well, I had a few suggestions (thanks), but:

>> > SIOCADDRT: Invalid argument

# /sbin/route add -net 127.0.0.0 netmask 255.0.0.0
SIOCADDRT: No such device

# /sbin/route add -net 127.0.0.0 dev lo
SIOCADDRT: Invalid argument

>> You might want to route add -net 127.0.0.0 lo

# /sbin/route add -net 127.0.0.0 lo
SIOCADDRT: Invalid argument

Also,

# /sbin/route add -net 127.0.0.0 netmask 255.0.0.0 dev lo
SIOCADDRT: File exists

All this with

# ifconfig -a
lo Link encap:Local Loopback

and

# netstat -rn

Confused.
