.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.
