tftpd - The DARPA Trivial File Transfer Protocol (TFTP) server
/usr/sbin/tftpd [-d] [-r pathname] [directory ...]
Specifies that the name of the file is sent to syslogd. Specifies the relative pathname a user can specify to transfer a file that has no path associated with it. For example, -r /tmp/tftp causes /tmp/tftp to be prefixed to a file that has no path and the file is copied to and from the directory /tmp/tftp. Only one directory path can be specified with this option.
The tftpd daemon is a server that supports the DARPA (Defense Advanced Research Projects Agency) Trivial File Transfer Protocol. The TFTP server operates at the port indicated in the tftp service description; see services(4). 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 can 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 implication should be considered before enabling tftp service. The server should have the user ID with the lowest possible privilege.
Access to files may be restricted by invoking tftpd with a list of directories and 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.
The tftpd daemon validates the files that it has to transfer against the /etc/tftptab file. If you are transferring files that are not publicly readable or not in the directories listed on the command line, you must make certain that those files are listed in the /etc/tftptab file.
The maximum number of directories allowed in the directory list are 62. The maximum number of files allowed in /etc/tftptab file is 256.
