NAME
rhosts, .rhosts − Specifies remote users that can use a local user account
SYNOPSIS
$HOME/.rhosts
DESCRIPTION
The .rhosts file contains a list of remote users who are not required to supply a login password when they execute the rcp, rlogin, and rsh commands using a local user account. This file is a hidden file in your home directory and must be owned by you or by the root user. The permissions of the .rhosts file should be set to 600 (read and write by owner only). Each entry in the file is of the form:
host user
where host is the name of the remote host and user is the login name of the remote user. If the remote host is in a different domain than the local host, the full domain name must be specified.
The user field is optional. If this field is omitted, any user on the specified remote host is exempt from providing a password, and is assumed to have the same username on both the local and remote hosts.
EXAMPLES
The following sample entries in the /u/chen/.rhosts file on host zeus allow users moshe and pierre at remote host venus to log in to user chen’s home directory on host zeus:
venus moshe
venus pierre
