If the server in question is behind a modem our router or something (like most home servers), this will only tell you if the router/modem is online. Netcat would normally be more ideal, like this:
This checks to see if there is anything listening in port 22 (standard SSH port) on the server you're testing. It will wait up to 3 seconds per attempt before it times out, and it will make 5 total attempts.
