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
services 5 .
The server is normally started by
inetd 8 .
The use of
tftp 1
does not require an account or password on the remote system.
Due to the lack of authentication information,
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.
Access to files may be controlled by invoking
tftpd
with a list of directories by including pathnames
as server program arguments in
/etc/inetd.conf .
In this case access is restricted to files whose names are prefixed by
the one of the given directories. If no directories are supplied the
default is
/tftpboot .
To give out access to the whole filesystem, should this be desired for
some reason, supply
/
as an argument.
