That happens indeed when not starting euler.Codd as root
on linux. Hmm.. the default port is 80 and can be specified
explicitly with java euler.Codd --port 80 --chatty 0
and when the port is not allowed, it retries port++ till it
finds a port that is fine (1024 in your case).
Port 80 is a convenience when working with reasoner argument
uri's that are served via localhost, but I see that your
example should also work as
wget -q -O-
