Downloaded binary from releases, -ssh doesn’t work.

Running on Ubuntu 16.04

Attempting to run elktalk on the ES node itself gives an error about not being able to connect either, but a curl works.

ERROR: Could not connect Elasticsearch client to http://127.0.0.1:9200: no Elasticsearch node available.
