RHOSTS(5)						     Linux Programmer's Manual							 RHOSTS(5)

NAME
       $HOME/.rhosts - grants or denies password-free r-command access to a specific user account

DESCRIPTION
       The  .rhosts file allows or denies a user who has an account on the local host to use the r-commands (e.g. rlogin, rsh or rcp) without sup-
       plying a password.

       The file uses the following format:

       hostname [username]

       Such an entry grants password-free r-command access for the user with the login name username from the remote host hostname.   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.

       Netgroups can be specified by preceeding the netgroup by an @ sign.

       The .rhosts file must have permissions 600 (that is, readable and writable only by the owner).
