TFTPD(8)

NAME
tftpd - DARPA Trivial File Transfer Protocol server

SYNOPSIS
/etc/tftpd [ -c <rootdir> ] [ -d ] [ -r <filter> ]

DESCRIPTION
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 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.

OPTIONS

-c  Pathname of a directory that is considered the rootdirectory for all transfers. N.B. tftpd does not actually perform a chroot(2) call; you should be aware of the security implications and you probably should run the server from an unpriviledged account.

-d  Increased debugging level.

-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.
