atmarpd(8)

NAME

     atmarpd -- ATMARP/SCSP interface daemon

SYNOPSIS

     atmarpd [-d] [-l <log_file>] <net_intf> ...

DESCRIPTION

     The atmarpd utility provides an interface between the ATMARP server in
     the kernel and the SCSP daemon for the Host ATM Research Platform (HARP)
     networking software.  The atmarpd utility 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 syn-
     chronization can take place.

     When atmarpd starts, it parses its command line and puts itself into the
     background.

     The command-line options are:

     -l <log_file>  Specify that atmarpd is to write log messages to the file
		    named <log_file> rather than to the system log.

     -d 	    Specify that atmarpd is to be run in debug mode.  In debug
		    mode, atmarpd is not put into the background.  Log mes-
		    sages are written to standard output instead of to the log
		    file.

     <net_intf>     Specify 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.

SIGNAL PROCESSING

     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).

FILES

     /tmp/atmarpd.<pid>.<seq>.out
	     Debugging information dump file name.  The atmarpd utility writes
	     a summary of its control blocks to this file when it receives a
	     SIGINT signal.  <pid> is the process ID of the daemon and <seq>
	     is a sequence number which is incremented every time a dump is
	     taken.
