Ah, slightly different from what I tried.

I did

ifconfig eth0 down

and then

ifconfig eth0 up

and it reported success using the old IP address, even when it was only 
connected to the hub, which had been disconnected from the rest of the 
network and doesn't do DHCP.  So, I figured that command wasn't renewing 
the lease.

I tried your command and it did indeed renew the lease.

What's the difference between your command and mine?  Why doesn't 
ifconfig renew the lease?
