hostname [ username ]
If no user name is specified, then the line indicates that root on the specified host can connect to the filer's remote shell daemon.
Since the only local user the filer recognizes is root, a non-root remote user must type:
adminhost% rsh -l root toaster command
Use multiple lines to grant access to multiple users on the same host.
adminhost
adminhost joe_smith
With the above hosts.equiv entries, the root user on the remote system would type:
adminhost# rsh toaster command
and user joe_smith would type:
adminhost% rsh -l root toaster command
