The .Tn kdumpd server operates on UDP port 1069, although this may be configurable in the future. The server should be started by .Xr inetd 8 . .Pp The server should have the user ID with the lowest possible privilege, usually the user "nobody". The directory specified as a server program argument in .Pa /etc/inetd.conf directs the server to store kernel cores in that directory and nowhere else. The server returns an EEXIST error to the remote kernel if it receives a request for an existing file - i.e. only new files can be created. The server also disallows path specifications in the incoming file name. .Sh HISTORY The .Nm command is based on Berkeley .Xr tftpd 8 by way of FreeBSD, with several modifications.
