NAME

       tftpd - The DARPA Trivial File Transfer Protocol (TFTP) server

SYNOPSIS

       /usr/sbin/tftpd [-b] [-d] [-r pathname] [-t interval] [directory ...]

FLAGS

       Instructs  tftpd to not respond to broadcast requests.  Specifies that the name of the file and other debug information 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.	Specifies the amount of time, in seconds, that tftpd waits  before  it	recognizing  a	connection
       timeout.  The default interval is 25 seconds.

DESCRIPTION

       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 appropri-
       ate  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 pub-
       licly 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.

RESTRICTION

       The maximum number of directories allowed in the directory list are 62.	The maximum number of files allowed in /etc/tftptab file is 256.

FILES

       Specifies the command path
