NAME

     kdumpd -- Mac OS X remote kernel core dump server

SYNOPSIS

     /usr/libexec/kdumpd [directory]

DESCRIPTION

     Kdumpd is a server which receives kernel states in the form of a core dump from a remote Mac OS X machine.  The kdumpd server operates on UDP
     port 1069, although this may be configurable in the future.  The server should be started by inetd(8).

     The server should have the user ID with the lowest possible privilege, usually the user "nobody".	The directory specified as a server pro-
     gram argument in /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.

HISTORY

     The kdumpd command is based on Berkeley tftpd(8) by way of FreeBSD, with several modifications.

NAME

       tftpd - The DARPA Trivial File Transfer Protocol (TFTP) server

SYNOPSIS

       /usr/sbin/tftpd [-b] [-d] [-r pathname] [-t interval] [directory ...]

FLAGS

       Instructs  tftpd to not respond to broadcast requests.  Specifies that the name of the file and other debug information is sent to syslogd.
       Specifies the relative pathname a user can specify to transfer a file that has no path associated  with	it.   For  example,  -r  /tmp/tftp
       causes  /tmp/tftp to be prefixed to a file that has no path and the file is copied to and from the directory /tmp/tftp.	Only one directory
       path can be specified with this option.	Specifies the amount of time, in seconds, that tftpd waits  before  it	recognizing  a	connection
       timeout.  The default interval is 25 seconds.

DESCRIPTION

       The  tftpd daemon is a server that supports the DARPA (Defense Advanced Research Projects Agency) Trivial File Transfer Protocol.  The TFTP
       server operates at the port indicated in the tftp service description; see services(4).	The server is normally started by inetd(8).

       The use of tftp does not require an account or password on the remote system.  Due to the lack of authentication  information,  tftpd  will
       allow  only  publicly readable files to be accessed.  Files can be written only if they already exist and are publicly writable.  Note that
       this extends the concept of ``public'' to include all users on all hosts that can be reached through the network; this may not be appropri-
       ate  on	all  systems,  and its implication should be considered before enabling tftp service.  The server should have the user ID with the
       lowest possible privilege.

       Access to files may be restricted by invoking tftpd with a list of directories and including  pathnames	as  server  program  arguments	in
       /etc/inetd.conf.  In this case, access is restricted to files whose names are prefixed by the one of the given directories.

       The tftpd daemon validates the files that it has to transfer against the /etc/tftptab file. If you are transferring files that are not pub-
       licly readable or not in the directories listed on the command line, you must make certain that those files are listed in the  /etc/tftptab
       file.

RESTRICTION

       The maximum number of directories allowed in the directory list are 62.	The maximum number of files allowed in /etc/tftptab file is 256.

FILES

       Specifies the command path
