39: .Sh NAME
40: .Nm tftp
41: .Nd trivial file transfer program
42: .Sh SYNOPSIS
43: .Nm tftp
44: .Op Ar host
45: .Sh DESCRIPTION
46: .Nm Tftp
47: is the user interface to the Internet
48: .Tn TFTP
49: (Trivial File Transfer Protocol),
50: which allows users to transfer files to and from a remote machine.
51: The remote
52: .Ar host
53: may be specified on the command line, in which case
54: .Nm tftp
55: uses
56: .Ar host
57: as the default host for future transfers (see the
58: .Cm connect
59: command below).
60: .Sh COMMANDS
61: Once
62: .Nm tftp
63: is running, it issues the prompt
64: .Ql tftp>
65: and recognizes the following commands:
66: .Pp
67: .Bl -tag -width verbose -compact
68: .It Cm \&? Ar command-name ...
69: Print help information.
70: .Pp
71: .It Cm ascii
72: Shorthand for "mode ascii"
73: .Pp
74: .It Cm binary
75: Shorthand for "mode binary"
76: .Pp
77: .It Cm connect Ar host-name Op Ar port
78: Set the
79: .Ar host
80: (and optionally
81: .Ar port )
82: for transfers.
83: Note that the
84: .Tn TFTP
85: protocol, unlike the
86: .Tn FTP
87: protocol,
88: does not maintain connections between transfers; thus, the
89: .Cm connect
90: command does not actually create a connection,
91: but merely remembers what host is to be used for transfers.
92: You do not have to use the
93: .Cm connect
94: command; the remote host can be specified as part of the
95: .Cm get
96: or
97: .Cm put
98: commands.
99: .Pp
100: .It Cm get Ar filename
101: .It Cm get Ar remotename localname
102: .It Cm get Ar file1 file2 ... fileN
103: Get a file or set of files from the specified
104: .Ar sources .
105: .Ar Source
106: can be in one of two forms:
107: a filename on the remote host, if the host has already been specified,
108: or a string of the form
109: .Ar hosts:filename
110: to specify both a host and filename at the same time.
111: If the latter form is used,
112: the last hostname specified becomes the default for future transfers.
113: .Pp
114: .It Cm mode Ar transfer-mode
115: Set the mode for transfers;
116: .Ar transfer-mode
117: may be one of
118: .Em ascii
119: or
120: .Em binary .
121: The default is
122: .Em ascii .
123: .Pp
124: .It Cm put Ar file
125: .It Cm put Ar localfile remotefile
126: .It Cm put Ar file1 file2 ... fileN remote-directory
127: Put a file or set of files to the specified
128: remote file or directory.
129: The destination
130: can be in one of two forms:
131: a filename on the remote host, if the host has already been specified,
132: or a string of the form
133: .Ar hosts:filename
134: to specify both a host and filename at the same time.
135: If the latter form is used,
136: the hostname specified becomes the default for future transfers.
137: If the remote-directory form is used, the remote host is
138: assumed to be a
139: .Tn UNIX
140: machine.
141: .Pp
142: .It Cm quit
143: Exit
144: .Nm tftp .
145: An end of file also exits.
146: .Pp
147: .It Cm rexmt Ar retransmission-timeout
148: Set the per-packet retransmission timeout, in seconds.
149: .Pp
150: .It Cm status
151: Show current status.
152: .Pp
153: .It Cm timeout Ar total-transmission-timeout
154: Set the total transmission timeout, in seconds.
155: .Pp
156: .It Cm trace
157: Toggle packet tracing.
158: .Pp
159: .It Cm verbose
160: Toggle verbose mode.
161: .El
162: .Sh BUGS
163: .Pp
164: Because there is no user-login or validation within
165: the
166: .Tn TFTP
167: protocol, the remote site will probably have some
168: sort of file-access restrictions in place. The
169: exact methods are specific to each site and therefore
170: difficult to document here.
171: .Sh HISTORY
172: The
173: .Nm
174: command appeared in
175: .Bx 4.3 .
