-h --host

-h hostname or --host hostname specifies the host name of the machine on which the server is running.

The following requirements and restrictions apply:

• If you use client authentication with a Kerberos connection method of either gss or krb5, you must specify -h hostname.
• If you use client authentication with a "local" connection type specified, and you want to match the client authentication entry, do not use -h hostname.
