+.Sh NAME
+.Nm tftpd
+.Nd
+.Tn DARPA
+Trivial File Transfer Protocol server
+.Sh SYNOPSIS
+.Nm tftpd
+.Op Ar directory ...
+.Sh DESCRIPTION
+.Nm Tftpd
+is a server which supports the
+.Tn DARPA
+Trivial File Transfer
+Protocol.
+The
+.Tn TFTP
+server operates
+at the port indicated in the
+.Ql tftp
+service description;
+see
+.Xr services 5 .
+The server is normally started by
+.Xr inetd 8 .
+.Pp
+The use of
+.Xr tftp 1
+does not require an account or password on the remote system.
+Due to the lack of authentication information, 
+.Nm 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
+.Dq 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.
+.Pp
+Access to files may be restricted by invoking
+.Nm tftpd
+with a list of directories by including pathnames
+as server program arguments in
+.Pa /etc/inetd.conf .
+In this case access is restricted to files whose
+names are prefixed by the one of the given directories.
