NAME
      htable - convert DoD Internet format host table

SYNOPSIS
      htable filename

DESCRIPTION
      htable converts a host table in the format specified by RFC 952 to the
      format used by the network library routines.  Three files are created as
      a result of running htable:  hosts, networks, and gateways.  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.

      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.

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