NAME
       rhosts, .rhosts, shosts, .shosts - Specifies remote users who can use a
       local user account

SYNOPSIS
       $HOME/.rhosts

       $HOME/.shosts

DESCRIPTION
       The file contains a list of remote users who are not required to supply
       a  login	 password when they use the local user account and execute the
       rcp, rlogin, and rsh commands.

       The file contains a list of remote users who are not required to supply
       a  login	 password when they use the local user account and execute the
       scp2, sftp2, and ssh2 Secure Shell commands or the rcp, rlogin, and rsh
       commands when they are configured to use a Secure Shell connection. See
       Security Administration for more information  about  configuring	 these
       commands to use a Secure Shell connection.

       The  file  is read by the rlogind, rshd, and Secure Shell sshd daemons.
       The file is read only the the Secure Shell sshd daemon.	If both	 files
       exist, the Secure Shell daemon reads the file first, then the file.  If
       either of these files allows access  for	 a  particular	connection,  a
       Secure Shell connection is used, even if the other file forbids it.

       The file and file are a hidden files in a user's home directory.	 These
       files must be owned by the user or  the	root  user  and	 must  not  be
       writable	 by group or world, otherwise, it is not used.	Although it is
       not required, it is recommended to set the permissions of  these	 files
       to 600, so the file is not readable by group or world.

       Each entry in the file and file is of the following form:

       host [user]

       where:  The  fully qualified domain name of the remote host.  The login
       name of the remote user. This field is optional. If a user name is  not
       specified, any user on the specified remote host is exempt from provid‐
       ing a password, and is assumed to have the same username	 on  both  the
       local and remote hosts.

       Optionally, in the and file you can specify a NIS netgroup name for the
       host name, user name, or both.

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

       hostname username +@netgroup

       The following entries are negative:

       -hostname -username -@netgroup

       In addition, in the file you can use the plus sign (+) in place of  the
       host  name or user name. In place of the host name, it means any remote
       host. In place of the user name, it means any user.   The  use  of  the
       plus  sign  in  this way is not supported in the file or in the file if
       you configured the rcp, rlogin, and rsh commands to use a Secure	 Shell
       connection. See Security Administration for more information about con‐
       figuring these commands to use a Secure Shell connection.
