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. BSD

tftpd -- DARPA Trivial File Transfer Protocol server SYNOPSIS
tftpd [-n] [-s] [directory ...] DESCRIPTION
Tftpd is a server which supports the DARPA Trivial File Transfer Protocol. The TFTP server operates at the port indicated in the 'tftp' ser- vice description; see services(5). The server is normally started by inetd(8). The use of tftp(1) 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 may 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 appropriate on all systems, and its implications should be considered before enabling tftp service. The server should have the user ID with the lowest possible privilege. Access to files may be controlled by invoking tftpd with a list of directories by 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. If no directories are supplied the default is /tftpboot. To give out access to the whole filesystem, should this be desired for some reason, supply / as an argument. Unfortunately, on multi-homed systems, it is impossible for tftpd to determine the address on which a packet was received. As a result, tftpd uses two different mechanisms to guess the best source address to use for replies. If the socket that inetd(8) passed to tftpd is bound to a particular address, tftpd uses that address for replies. Otherwise, tftpd uses ``UDP connect'' to let the kernel choose the reply address based on the destination of the replies and the routing tables. This means that most setups will work transparently, while in cases where the reply address must be fixed, the virtual hosting feature of inetd(8) can be used to ensure that replies go out from the correct address. These considerations are important, because most tftp clients will reject reply packets that appear to come from an unexpected address. The options are: -n Suppresses negative acknowledgement of requests for nonexistent relative filenames. -s All absolute filenames are treated as if they were preceded by the first directory argument, or /tftpboot if there is none.
