NAME
      erpcd - Annex network services daemon

SYNOPSIS
      /etc/erpcd [ -d [ udpport ] ] [ -D[level] ]

DESCRIPTION
      erpcd is the Annex network services daemon.  It is normally started at
      boot time from the rc(8) file.

      The erpcd daemon is responsible for two services:  the block file server
      used by the Annex to access host files, bfs, and the Annex access control
      protocol server that handles security requests, acp.  In both cases,
      erpcd listens at a well-known UDP port (name "erpc", 121/udp) for
      messages indicating a request for services from an Annex.  It
      authenticates these messages and then reads the file /etc/eservices to
      determine what types of requests to service and which server to execute.

      Although the well-known port can be specified with the -d number, the
      default as specified in /etc/eservices should be used.  The -d option
      used without the port number argument turns on socket level debugging.
      Note that there is a space between the -d and the number.  The -D option
      puts erpcd in a debug mode where it does not detach from the invokers tty
      and instead prints out extensive debugging information.  The amount of
      debugging information can be increased by giving a debugging level with
      the -D option.  Note that there is no space between the -D and the
      number.

      The bfs service is used by the Annex to down-load various host files from
      a server host and to up-load crash dump images to a server host. All such
      files are resident in /usr/spool/erpcd/bfs or its subdirectories.  The
      dump file is named by prefixing "dump." to the Internet address of the
      Annex.   The dump file names are unique for each Annex but not for each
      crash dump. An existing dump file is overwritten if the same Annex
      crashes again.  A dump file is slightly larger than the amount of memory
      in the Annex.

      When the Annex boots, it uses the bfs service to request three files.
      First, the boot rom obtains the Annex operational code that is loaded
      into Annex main memory. As part of its booting procedure, the Annex
      operational code requests the files gateways and rotaries.  The Annex
      first requests this file from the host whose address is specified by the
      na parameter prefloadaddr.  If this host does not respond, the Annex
      broadcasts the request.  An empty or missing gateways or rotaries file
      simply means there is no configuration in that area.  It is preferable to
      use an empty file rather than not having the file exist, as the Annex
      will find the empty file and thus won't have to wait for its open request
      to timeout.  The gateways file is described in gateways(5).  The rotaries
      file is described in rotaries(5).

      The acp service is used by the Annex to implement host based security
      policies that govern Annex operations. See the Annex Network
      Administrator's Guide for more information on the acp service.

NOTES
      The dump subdirectories should be carefully monitored and any crash dumps
      should be sent to your service representative.

BUGS
      If the gateways or rotaries files are not present on any host, the Annex
      may take up to an extra minute to complete its booting procedures.

      The -d option takes a space before number; the -D option does not.
