NAME
     netdumpd -- receive kernel	core dumps over	the network

SYNOPSIS
     netdumpd [-a addr]	[-D] [-d dumpdir] [-i postscript] [-P pidfile]
	      [-p path]

DESCRIPTION
     The netdumpd utility listens on a UDP socket for incoming connections
     from a FreeBSD kernel core	dumping	over the network.

     The following options are available:

     -a	     Bind the daemon to	the given address "addr".

     -D	     Run the utility in	debugging mode.	 The daemon version is not en-
	     tered while the output is printed entirely	on the console.

     -d	     Save the core dumps to the	specified "dumpdir" directory.	The
	     default directory is /var/crash.

	     Clients may optionally specify a relative directory path when
	     initiating	a netdump.  This path is appended to "dumpdir" to ob-
	     tain a directory in which to save the core	dump.  The relative
	     path may not contain ".." components.  Additionally, no symbolic
	     link in the path may contain ".." components.

     -i	     Execute the script	"script" after each dump received.  The	script
	     receives the same parameters as the -b prescript.

     -P	     Specify an	alternative file in which to store the process ID.
	     The default is /var/run/netdumpd.pid.

     -p	     A directory path relative to "dumpdir" in which to	save core
	     dumps for clients that do not specify a relative path.  Core
	     dumps from	clients	that specify an	invalid	directory path are
	     saved in the default directory.

SECURITY
     The netdumpd utility does not perform any authentication of clients and
     should therefore be configured to listen only to trusted networks.
     netdumpd can be made to write an arbitrary	amount of client data to a lo-
     cally-mounted filesystem.
