FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

atmarpd - ATMARP/SCSP interface daemon



      atmarpd - ATMARP/SCSP interface daemon


      atmarpd [-d] [-l 〈log_file〉] 〈net_intf〉 ...


      Atmarpd provides an interface between the ATMARP server in the kernel and
      the SCSP daemon for the Host ATM Research Platform (HARP) networking
      software.  Atmarpd reads the ATMARP cache from the kernel periodically
      and passes any updated entries to scspd(8) so they will be propagated to
      remote servers.  It also accepts updated entries that remote servers have
      sent to scspd(8) and, if they are new or more up to date than current
      entries, installs them in the kernel’s ATMARP cache.  Both atmarpd and
      scspd(8) must be running before any ATMARP cache synchronization can take
      When atmarpd starts, it parses its command line and puts itself into the
      The command-line options are:
      -l 〈log_file〉  Specifies that atmarpd is to write log messages to the
                     file named 〈log_file〉 rather than to the system log.
      -d             Specifies that atmarpd is to be run in debug mode.  In
                     debug mode, atmarpd is not put into the background.  Log
                     messages are written to standard output instead of to the
                     log file.
      〈net_intf〉     Specifies the network interface(s) for which the host is
                     providing ATMARP service and whose caches are to be syn‐
                     chronized using SCSP.  If multiple network interface names
                     are specified, atmarpd will provide an interface to
                     scspd(8) for the servers on all the specified interfaces.
      The following signals can be used to control atmarpd:
      SIGINT  Dump debugging information to a file.  When it receives a SIGINT
              signal, atmarpd dumps a summary of its control blocks to a text
              file (see FILES).


              Debugging information dump file name.  Atmarpd writes a summary
              of its control blocks to this file when it receives a SIGINT sig‐
              nal.  〈pid〉 is the process ID of the daemon and 〈seq〉 is a
              sequence number which is incremented every time a dump is taken.

      Results are unpredictable if multiple instantiations of atmarpd are run
      simultaneously for a given network interface.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
