HOSTS.EQUIV(5)

NAME

     hosts.equiv, .rhosts -- trusted remote host and user name data base

DESCRIPTION

     The hosts.equiv and .rhosts files contain information regarding trusted
     hosts and users on the network.  For each host a single line should be
     present with the following information:

     simple

	   hostname [username]

     or the more verbose

	   [+-][hostname|@netgroup] [[+-][username|@netgroup]]

     A ``@'' indicates a host by netgroup or user by netgroup.	A single ``+''
     matches all hosts or users.  A host name with a leading ``-'' will reject
     all matching hosts and all their users.  A user name with leading ``-''
     will reject all matching users from matching hosts.

     Items are separated by any number of blanks and/or tab characters.  A
     ``#'' indicates the beginning of a comment; characters up to the end of
     the line are not interpreted by routines which search the file.

     Host names are specified in the conventional ``.'' (dot) notation using
     the inet_addr(3) routine from the Internet address manipulation library,
     inet(3).  Host names may contain any printable character other than a
     field delimiter, newline, or comment character.

     For security reasons, a user's .rhosts file will be ignored if it is not
     a regular file, or if it is not owned by the user, or if it is writable
     by anyone other than the user.

EXAMPLES

	   bar.com foo

     Trust user ``foo'' from host ``bar.com''.

	   +@allclient

     Trust all hosts from netgroup ``allclient''.

	   +@allclient -@dau

     Trust all hosts from netgroup ``allclient'' and their users except users
     from netgroup ``dau''.
