Okay, I tried that. That gave me the 'Network Settings' interface. The only 
'Connection ' listed is 'Wired Connection (Address: dhcp)'. It won't let me 
make a brand-new connection - onl an alias. So, I created an alias 'devon1' 
with ip adress 191.168.0.9 but it still won't show up when I run 
/sbin/ifconfig.
