htable(1M)                                                htable(1M)


       NAME
             htable - convert DoD Internet format host table

       SYNOPSIS
             htable [-c connected-nets] [-l local-nets] [input-file]

       DESCRIPTION
             The htable command converts a host table in the format
             specified by RFC 952 to the format used by the network library
             routines.

          Files
             localhosts
             localnetworks
             localgateways

          Output
             Three files are created as a result of running htable: the
             hosts file, the networks file, and the gateways file.

                   The hosts file is used by the gethostent(3N) routines in
                   mapping host names to addresses.

                   The networks file is used by the getnetent(3N) routines
                   in mapping network names to numbers.

                   The gateways file is used by the routing daemon in
                   identifying ``passive'' Internet gateways; see
                   routed(1M) for an explanation.

       USAGE
             If any of the files localhosts, localnetworks, or
             localgateways are present in the current directory, the file's
             contents are prepended to the output file without
             interpretation.  This allows sites to maintain local aliases
             and entries which are not normally present in the master
             database.

             If the gateways file is to be used, a list of networks to
             which the host is directly connected is specified with the -c
             option.  The networks, separated by commas, may be given by
             name, or the Internet-standard ``.'' (dot) notation.  htable
             only includes gateways which are directly connected to one of
             the specified networks, or which can be reached from another
             gateway on a connected network.

            If the -l option is given with a list of networks (in the same
            format as the networks specified with the -c option), these
            networks will be treated as ``local,'' and information about
            hosts on local networks is taken only from the localhosts
            file.  Entries for local hosts from the main database will be
            omitted.  This allows the localhosts file to completely
            overrid any entries in the input file.

            htable is best used in conjunction with the gettable(1M)
            program which retrieves the DoD Internet host table from a
            host.

      NOTICES
            htable does not properly calculate the gateways file.
