  .rhosts

  NAME

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

  DESCRIPTION

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

    hostname [username]

    Items are separated by any number of blanks, tab characters, or both. A
    pound sign (#) indicates the beginning of a comment; characters up to the
    end of the line are not interpreted by routines that search the file.

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

    If a user name is specified, only that user from the specified host can
    log on to the local computer. If a user name is not specified, any user on
    the specified host can log on.

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

  EXAMPLE

    somehost kim
        Trust user kim from host somehost.

  FILES

    /etc/hosts.equiv
        The hosts.equiv file resides in /etc.

    $HOME/.rhosts
        .rhosts file resides in $HOME.

  NOTE

    Historically, most other UNIX systems have used one of these formats:

    [+-]hostname|@netgroup
    [+-]hostname|@netgroup1 [[+-]username|@netgroup2]

    This format is not supported by Interix, however.
