+This is tftp-hpa-0.12; this version was put out by H. Peter Anvin
+<hpa@zytor.com>.
+
+This is a conglomerate of a number of versions of the BSD TFTP code,
+ported to Linux, although it should work on mostly any POSIX-compliant
+OS with sockets.
+
+The core software was taken from OpenBSD (CVS source as of
+1999-09-21). I believe this was the most secure source base available
+at the time I obtained this code, and it included support for the -s
+and -c options.
+
+The un-BSD-ized Makefiles and a lot of the configure macros were taken
+from netkit-tftp-0.10 by David Holland; I also followed this example
+and modernized the code style throughout.
+
+Patches by Markus Gutschke and Gero Kuhlmann were the basis for the
+option negotiation as well as the "blksize" and "tsize" option
+support, although I made a fair amount of mostly stylistic changes to
+their code.
+
+Adding the -r option (disable a specific option), the "timeout"
+option, and converting to using autoconf for setup was my own code, as
+are any bugs introduced in this merge.

+.Sh NAME
+.Nm tftp
+.Nd trivial file transfer program
+.Sh SYNOPSIS
+.Nm tftp
+.Op Ar host
+.Sh DESCRIPTION
+.Nm tftp
+is the user interface to the Internet
+.Tn TFTP
+(Trivial File Transfer Protocol),
+which allows users to transfer files to and from a remote machine.
+The remote
+.Ar host
+may be specified on the command line, in which case
+.Nm tftp
+uses
+.Ar host
+as the default host for future transfers (see the
+.Ic connect
+command below).
+.Sh COMMANDS
+Once
+.Nm tftp
+is running, it issues the prompt
+.Ql tftp>
+and recognizes the following commands:
+.Pp
+.Bl -tag -width verbose -compact
+.It Ic \&? Ar command-name Op Ar ...
+Print help information.
+.Pp
+.It Ic ascii
+Shorthand for
+.Ic mode ascii .
+.Pp
+.It Ic binary
+Shorthand for
+.Ic mode binary .
+.Pp
+.It Ic connect Ar host Op Ar port
+Set the
+.Ar host
+(and optionally
+.Ar port )
+for transfers.
+Note that the
+.Tn TFTP
+protocol, unlike the
+.Tn FTP
+protocol,
+does not maintain connections between transfers; thus, the
+.Ic connect
+command does not actually create a connection,
+but merely remembers what host is to be used for transfers.
+You do not have to use the
+.Ic connect
+command; the remote host can be specified as part of the
+.Ic get
+or
+.Ic put
+commands.
+.Pp
+.It Ic get Ar filename
+.It Ic get Ar remotename localname
+.It Ic get Ar file Op Ar ...
+Get a file or set of files from the specified
+.Ar sources .
+.Ar source
+can be in one of two forms:
+a filename on the remote host, if the host has already been specified,
+or a string of the form
+.Ar hosts:filename
+to specify both a host and filename at the same time.
+If the latter form is used,
+the last hostname specified becomes the default for future transfers.
+.Pp
+.It Ic mode Ar transfer-mode
+Set the mode for transfers;
+.Ar transfer-mode
+may be one of
+.Ic ascii
+or
+.Ic binary .
+The default is
+.Ic ascii .
+.Pp
+.It Ic put Ar file
+.It Ic put Ar localfile remotefile
+.It Ic put Ar file1 file2 ... fileN remote-directory
+Put a file or set of files to the specified
+remote file or directory.
+The destination
+can be in one of two forms:
+a filename on the remote host, if the host has already been specified,
+or a string of the form
+.Ar hosts:filename
+to specify both a host and filename at the same time.
+If the latter form is used,
+the hostname specified becomes the default for future transfers.
+If the remote-directory form is used, the remote host is
+assumed to be a
+.Tn UNIX
+machine.
+.Pp
+.It Ic quit
+Exit
+.Nm tftp .
+An end-of-file also exits.
+.Pp
+.It Ic rexmt Ar retransmission-timeout
+Set the per-packet retransmission timeout, in seconds.
+.Pp
+.It Ic status
+Show current status.
+.Pp
+.It Ic timeout Ar total-transmission-timeout
+Set the total transmission timeout, in seconds.
+.Pp
+.It Ic trace
+Toggle packet tracing.
+.Pp
+.It Ic verbose
+Toggle verbose mode.
+.El
+.Sh BUGS
+Because there is no user login or validation within
+the
+.Tn TFTP
+protocol, the remote site will probably have some
+sort of file access restrictions in place. The
+exact methods are specific to each site and therefore
+difficult to document here.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.3 .

+.Sh NAME
+.Nm tftpd
+.Nd
+.Tn DARPA
+Trivial File Transfer Protocol server
+.Sh SYNOPSIS
+.Nm tftpd
+.Op Fl cs
+.Op Fl r Ar option...
+.Op Ar directory
+.Sh DESCRIPTION
+.Nm
+is a server which supports the
+.Tn DARPA
+Trivial File Transfer
+Protocol.
+The
+.Tn TFTP
+server operates
+at the port indicated in the
+.Ql tftp
+service description;
+see
+.Xr services 5 .
+The server is normally started by
+.Xr inetd 8 .
+.Pp
+The use of
+.Xr tftp 1
+does not require an account or password on the remote system.
+Due to the lack of authentication information,
+.Nm
+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
+.Dq 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.
+.Pp
+Access to files may be restricted by invoking
+.Nm
+with a list of directories by including pathnames
+as server program arguments in
+.Pa /etc/inetd.conf .
+In this case access is restricted to files whose
+names are prefixed by the one of the given directories.
+.Pp
+If the
+.Fl c
+flag is used,
+.Nm
+will allow new files to be created; otherwise uploaded files must already
+exist. Files are created with default permissions allowing anyone to read
+or write to them.
+.Pp
+When using the
+.Fl s
+flag with a directory name,
+.Nm
+will
+.Xr chroot 2
+on startup; therefore the remote host is not expected to pass the directory
+as part of the file name to transfer. This option is intended primarily for
+compatibility with SunOS boot ROMs which do not include a directory name.
+.Pp
+This version of
+.Nm
+supports RFC 2347 option negotiation; the current version supports the
+.Pa blksize
+(RFC 2348),
+.Pa blksize ,
+(RFC 2349), and
+.Pa timeout
+(RFC 2349) options. The
+.Fl r
+flag can be used to disable options individually; this may allow
+working around client bugs.
+.Sh SEE ALSO
+.Xr tftp 1 ,
+.Xr inetd 8
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .
+.Pp
+The
+.Fl s
+flag appeared in NetBSD 0.9a.
+.Pp
+The
+.Fl c
+flag was added in OpenBSD 2.1 .
+.Pp
+The
+.Fl r
+flag and RFC 2347 options were added by H. Peter Anvin based on
+patches by Markus Gutschke and Gero Kulhman.
