+.SH NAME
+tftpd \- DARPA Trivial File Transfer Protocol server
+.SH SYNOPSIS
+.B /etc/tftpd
+[
+.B \-d
+] [
+.I port
+]
+.SH DESCRIPTION
+.I Tftpd
+is a server which supports the DARPA Trivial File Transfer
+Protocol.  The TFTP server operates
+at the port indicated in the ``tftp'' service description;
+see
+.IR services (5).
+This port number may be overridden (for debugging purposes)
+by specifying a port number on the command line.  If the
+.B \-d
+option is specified, each socket created by
+.I tftpd
+will have debugging enabled (see SO_DEBUG in
+.IR socket (2)).
+.PP
+The use of
+.I tftp
+does not require an account or password on the remote system.
+Due to the lack of authentication information, 
+.I tftpd
+will allow only publicly readable files to be
+accessed.
+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.
+.SH "SEE ALSO"
+tftp(1C)
+.SH BUGS
+This server is known only to be self consistent
+(i.e. it operates with the user TFTP program,
+.IR tftp (1C)).
+Due to the unreliability of the transport protocol
+(UDP) and the scarcity of TFTP implementations,
+it is uncertain whether it really works.
+.PP
+The search permissions of the directories leading to the files accessed
+are not checked.
