[chord] Please help, Couldn't understand the error message..

[Frank Dabek]

Clone7,

	You are using a version of lsd that depends on an asynchronous
database. Our FAQ has not been updated to reflect this. Before you run
lsd you must start the database. Try something like:

adbd -S ./db_socket -d ./db_file &
lsd -j rose.cs.ntou.edu.tw:10000 -d ./db_socket

db_socket is a UNIX socket that lsd will use to talk to the database.
db_file is the actual Berkeley database file.

I'm not sure where you installed lsd and adbd but you might need to
specify a full path to one or both.

vis doesn't have anything to visualize unless you have lsd running.It
shouldn't segfault in any case, but you didn't miss anything because it did.
