Shutting down Oracle from a Client

I am running 8.0.5.1 under linux.

1. Can you shut down oracle from a client? (I can't imagine that you wouldn't be able to)
2. Can I run svrmgrl and specify a connection (connect username/password_at_server_in_tnsnames.ora) and issue a shutdown command?
3. What users have the privledges to startup and shutdown a database?
4. Where are those users defined? (OS level or DB level or Passwordfile?)

Thanks
