Unable to actually use it.

barnard -server "<our server>:64738" -username "Cloud" -password "<our password>" -certificate key.pem

With the missing info properly replaced in that, i run it and get a plain EOF with nothing else.

This syntax works for me
barnard -server=”server:port″ -username=”Cloud” -password="somepwd" -insecure=true -certificate=/home/user/path-to-certificate.pem
