.SH NAME
$HOME/.rhosts \- grants or denies password-free \fBr\fP-command access
to a specific user account
.SH DESCRIPTION
The \fB.rhosts\fP file allows or denies a user who has an account on the
local host to use the \fBr\fP-commands (e.g. \fBrlogin\fP, \fBrsh\fP or
\fBrcp\fP) without supplying a password.
.PP
The file uses the following format:
.TP
\fIhostname\fP \fI[username]\fP
.PP
Such an entry grants password-free \fBr\fP-command access for the user with
the login name \fIusername\fP from the remote host \fIhostname\fP.
If no user name is specified, the user must have the same login name on
the remote host and the local host. For security reasons you should always
use the FQDN of the hostname and not the short hostname.
.PP
Netgroups can be specified by preceeding the netgroup by an @ sign.
.PP
The \fB.rhosts\fP file must have permissions 600 (that is, readable and
writable only by the owner).
