NAME
tftpd - DARPA Trivial File Transfer Protocol server
SYNOPSIS
/usr/etc/in.tftpd
[-s]
[ homedir ]
DESCRIPTION
tftpd
is a server that supports the
DARPA
Trivial File Transfer Protocol (TFTP).
This server is normally started by
inetd(8C)
and operates at the port indicated in the
tftp
Internet service description in the
/etc/inetd.conf
file; see
inetd.conf(5)
for details.
Before responding to a request, the server attempts to change its
current directory to
homedir;
the default value is
/tftpboot.
OPTIONS
- -s
-
Secure. When specified, the directory change must succeed; and
the daemon also changes its root directory to
homedir.
-
The use of
tftp
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 lqpublicrq 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 this service.
tftpd
runs with the user
ID
and group
ID
set to
-2,
under the assumption that no files exist with that owner or group.
However, nothing checks this assumption or enforces this restriction.
FILES
/tftpboot/* filenames are IP addresses
