.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).
|
||
|
|
The server is normally started by
|
||
|
|
.IR inetd (8).
|
||
|
|
.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.
|
||
|
|
Files may be written only if they already exist and are publicly writable.
|
||
|
|
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.
|
||
|
|
The server should have the user ID with the lowest possible privilege.
|
||
|
|
.SH OPTIONS
|
||
|
|
.TP
|
||
|
|
.B \-c
|
||
|
|
Pathname of a directory that is considered the rootdirectory for all
|
||
|
|
transfers. N.B.
|
||
|
|
.I tftpd
|
||
|
|
does not actually perform a
|
||
|
|
.IR chroot (2)
|
||
|
|
call; you should be aware of the security implications and you
|
||
|
|
probably should run the server from an unpriviledged account.
|
||
|
|
.TP
|
||
|
|
.B \-d
|
||
|
|
Increased debugging level.
|
||
|
|
.TP
|
||
|
|
.B \-r
|
||
|
|
Pathname of a file that is considered to be a filter program. Whenever
|
||
|
|
a client tries to download this file, the filter will be started and
|
||
|
|
its output is send to the client. An arbitrary amount of these
|
||
|
|
filters can be specified.
