rhosts(4)
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.

  The .rhosts file is a hidden file in your home directory.  It must be owned
  by you or the root user and it must not be writable by group or world,
  otherwise, it is not used.  Moreover, although it is not required, it is
  sensible to set the permissions of the file to 600, so the file is not
  readable by group or world.

  Each entry in the file is of the following form:

       host [user]


  where:

  host
      The name of the remote host. If the remote host is in a different
      domain than the local host, the full domain name must be specified.

  user
      The login name of the remote user. This field is optional. If this
      field is not specified, 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.

  Optionally, an NIS netgroup name can be specified for the host name, user
  name, or both.

  Entries in the .rhosts file are either positive or negative. Positive
  entries allow access; negative entries deny access. The following entries
  are positive:

       hostname
       username
       +@netgroup

  In addition, the plus sign (+) can be used in place of the hostname or
  username. In place of the hostname, it means any remote host. In place of
  the username, it means any user.


  The following entries are negative:

       -hostname
       -username
       -@netgroup

EXAMPLES
  The following sample entries in the /u/chen/.rhosts file on host zeus allow
  users moshe and pierre at remote host venus and user robert at the hosts
  specified in the NIS netgroup chicago to log in to user chen's home
  directory on host zeus:

       venus moshe
       venus pierre
       +@chicago robert
