Shuts down on startup

[SpruceFan]

I've tried an older Mac. It supports SSH v.1. When I entered ssh -1 username x.x.x.x I got the response
ssh: could not resolve hostname username: nodename nor servname provided, or not known

I then tried the other LAN port on the NAS and received as a response:
ssh: connect to host x.x.x.x port 22: Connection refused

Trying the same command on the other NAS, the one for which I get the greyed MinimWatch icon, give the response immediately above.

Hope this helps. I'm completely stumped.
