  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.
