When to use the rsh command with user names and passwords

Under some circumstances, you should consider supplying a user name and a password when using the rsh protocol to run a command on the storage system.

If you are logged in ...	Then...
As root on a UNIX host that is listed in the storage system’s /etc/hosts.equiv file	You do not need to supply a user name or a password.
As a user other than root on a UNIX host that is listed in the storage system’s /etc/hosts.equiv file	You need to supply a user name and a password. The user name can be root or the name of an administrative user that has been defined on the storage system.

Note: To issue commands from a Remote Shell on a PC, you must always supply a user name for the PC in the storage system’s /etc/hosts.equiv file. For more information, see the na_hosts.equiv(5) man page.
