One small note: Some sites consider running a nmap scan of a system to be an attack, and may be illegal depending on where (and who) you are.

A nmap scan looks at open ports on the remote host, and may not be able to identify what the system is as it depends entirely on the services that may be running there.

Thanks for above info.
Do we have any other command?

Nope.

There is no guaranteed test that can - all depend on the information provided by the services that are running, either through error responses, the style of errors, and/or the initial connection prompts by the services.

And this is the same type of scan used by a virus attempting to find vulnerable services.
