38 .Sh NAME
39 .Nm kdumpd
40 .Nd Mac OS X remote kernel core dump server
41 .Sh SYNOPSIS
42 .Nm /usr/libexec/kdumpd
43 .Op Ar directory
44 .Sh DESCRIPTION
45 .Nm Kdumpd
46 is a server which receives
47 kernel states in the form of
48 a core dump from a remote
49 Mac OS X machine.
50 The
51 .Tn kdumpd
52 server operates
53 on UDP port 1069, although this
54 may be configurable in the future.
55 The server should be started by
56 .Xr inetd 8 .
57 .Pp
58 The server should have the user ID
59 with the lowest possible privilege,
60 usually the user "nobody".
61 The directory specified as a server
62 program argument in
63 .Pa /etc/inetd.conf
64 directs the server to store kernel cores
65 in that directory and nowhere else.
66 The server returns an EEXIST error
67 to the remote kernel if it receives a
68 request for an existing file - i.e.
69 only new files can be created. The server
70 also disallows path specifications in the
71 incoming file name.
72 .Sh HISTORY
73 The
74 .Nm
75 command is based on Berkeley
76 .Xr tftpd 8
77 by way of FreeBSD, with several modifications.
