[chord] Running Chord

[Frank Dabek]

Soseca,

	Does localhost.localdomain resolve to 192.168.0.10 on your machine? Try
something like:

lsd -j 127.0.0.1:10000 -l 127.0.0.1 -p 10000

the -l argument makes sure that lsd binds to the right address. Since
IDs are based on IP address, if it chooses a different address the
program may not recognize the node as valid.
