rhost(1M)

NAME
     rhost - set the attributes of remote hosts and networks.

SYNOPSIS
     /usr/etc/rhost [-l <lookup_host>] [-f <cfile>] [-r <remote>] [-k ] [-n ]
     [-d ]

DESCRIPTION
     On systems with TSIX networking enabled, the kernel uses an internal
     lookup table, called the internal Remote Host Database (RHDB), to enforce
     per host security policy.  The rhost command loads the RHDB with the
     attributes of remote hosts and networks, specified in /etc/rhost.conf.

   Options
     -l <lookup_host>
                     The -l option will check the RHDB for a host name and, if
                     it exists, will display the host's attributes.

     -f <cfile>      /etc/rhost.conf is the default file used to create the
                     RHDB.  Use the -f option to use an alternative
                     configuration file.  When using a different file other
                     then the default, make sure it has the appropriate
                     security policies.

     -r <remote>     The -r option is defined, but not used.

     -k              The -k option is used to list all recognized attributes.

     -n              The -n option checks the RHDB file only.

     -d              The -d option gives some debug information.

     -v              The -v option turns on verbose mode.

     The /etc/rhost.conf file consists, minimally, of a series of host
     attribute profile assignments of the form:

          <name>: = <attribute> = <value>: [<attribute> = <value>:]

     Newline characters within a host attribute profile must be escaped.  It
     is usually most convenient to specify a series of commonly used profiles
     as templates, then use the templates to assign the profiles to specific
     hosts.  A template looks exactly like a host profile assignment, except
     that one of the attribute-value pairs is default_spec = .:, for example:

          default_cipso: \
                    smm_type = single_level: \
                    nlm_type = cipso: \
                    default_spec = .:

          Either host names or IP addresses may be used to specify hosts.  If
          a host name is used, an entry for that host must appear in the local
          /etc/hosts file, as rhost is run before network information services
          (NIS) are available.  A wildcard IP address, that is, an address
          with zeros in some slots, may be used to specify a range of IP
          addresses.  For example,

               128.01.01.0:
               128.01.0.0:
               128.0.0.0:
               0.0.0.0:

          are valid host specifications. When rhost resolves addresses, it
          first looks for a complete address, followed by a wildcard with one
          zero byte, and so forth.  This allows the administrator to specify,
          for example:

               0.0.0.0:        The whole world is untrusted
               128.01.01.0:    Except this network, which speaks CIPSO
               128.01.01.01:   Except this host, which is TSIX.


          A sample copy of /etc/rhost.conf has been provided on your system.
          The file begins with a series of templates, including default_cipso
          and default_sgipso.  These templates are used later in the file to
          assign profiles to specific hosts for example:

               localhost:  default_spec = default_cipso:

          The following attributes are recognized:

          host_type
               The host_type attribute value will be printed when the RHDB is
