39: .Sh SYNOPSIS

1.9 jmc 41: .Op Ar host Oo Ar port Oc
1.1 deraadt 42: .Sh DESCRIPTION
1.6 aaron 43: .Nm
1.1 deraadt 44: is the user interface to the Internet
45: .Tn TFTP
46: (Trivial File Transfer Protocol),
47: which allows users to transfer files to and from a remote machine.
48: The remote
49: .Ar host
1.8 jmc 50: and
51: .Ar port
1.1 deraadt 52: may be specified on the command line, in which case
1.6 aaron 53: .Nm
1.8 jmc 54: uses them as the default for future transfers (see the
1.3 aaron 55: .Ic connect
1.1 deraadt 56: command below).
57: .Sh COMMANDS
58: Once
1.6 aaron 59: .Nm
1.1 deraadt 60: is running, it issues the prompt
1.10 jmc 61: .Ql tftp\*(Gt
1.1 deraadt 62: and recognizes the following commands:
63: .Pp
64: .Bl -tag -width verbose -compact
1.3 aaron 65: .It Ic \&? Ar command-name Op Ar ...
1.1 deraadt 66: Print help information.
67: .Pp
1.3 aaron 68: .It Ic ascii
69: Shorthand for
1.8 jmc 70: .Ic mode Ar ascii .
1.3 aaron 71: .Pp
72: .It Ic binary
73: Shorthand for
1.8 jmc 74: .Ic mode Ar binary .
1.1 deraadt 75: .Pp
1.13 ! jmc 76: .It Ic blksize Ar block-size
! 77: Set the block size in bytes for one packet.
! 78: The default value is 512 bytes.
! 79: Valid values are 8 bytes \(en 65464 bytes.
! 80: .Pp
1.3 aaron 81: .It Ic connect Ar host Op Ar port
1.1 deraadt 82: Set the
83: .Ar host
84: (and optionally
85: .Ar port )
86: for transfers.
87: Note that the
88: .Tn TFTP
89: protocol, unlike the
90: .Tn FTP
91: protocol,
92: does not maintain connections between transfers; thus, the
1.3 aaron 93: .Ic connect
1.1 deraadt 94: command does not actually create a connection,
95: but merely remembers what host is to be used for transfers.
1.4 aaron 96: You do not have to use the
1.3 aaron 97: .Ic connect
1.1 deraadt 98: command; the remote host can be specified as part of the
1.3 aaron 99: .Ic get
1.1 deraadt 100: or
1.3 aaron 101: .Ic put
1.1 deraadt 102: commands.

1.8 jmc 115: .Ar fileN
116: .Xc
117: Get a file or set of files from the remote host.
118: When using the
119: .Ar host
120: argument, the
121: .Ar host
122: will be used as the default host for future transfers.
123: If
124: .Ar localname
125: is specified,
126: the file is stored locally as
127: .Ar localname ,
128: otherwise the original filename is used.
129: .Pp
130: Note that it is not possible to download two files at the same time;
131: only one, three, or more than three files
132: can be downloaded at the same time.

1.3 aaron 134: .It Ic mode Ar transfer-mode
1.4 aaron 135: Set the mode for transfers;

1.8 jmc 152: .Ar remote-directory Oc
153: .Xc
154: Put a file or set of files to the remote host.
155: When using the
156: .Ar host
157: argument, the
158: .Ar host
159: will be used as the default host for future transfers.
160: If
161: .Ar remotename
162: is specified, the file is stored remotely as
163: .Ar remotename ,
164: otherwise the original filename is used.
165: If the
166: .Ar remote-directory
167: argument is used, the remote host is assumed to be a
1.1 deraadt 168: .Tn UNIX
169: machine.
170: .Pp
1.8 jmc 171: Note that files may only be written to if they already exist on the
172: remote host and are publicly writable.

1.13 ! jmc 193: .It Ic tout
! 194: Toggle the

! 196: option.
! 197: This option devlivers the retransmission-timeout,
! 198: which is set by
! 199: .Ic rexmt ,
! 200: to the server,
! 201: so the server uses the same retransmission-timeout as the client.

! 203: .It Ic tsize
! 204: Toggle the
! 205: .Ic tsize
! 206: option.

1.5 aaron 221: .Sh HISTORY
222: The
223: .Nm
224: command appeared in
225: .Bx 4.3 .
1.1 deraadt 226: .Sh BUGS
1.3 aaron 227: Because there is no user login or validation within
1.1 deraadt 228: the
229: .Tn TFTP
230: protocol, the remote site will probably have some
1.6 aaron 231: sort of file access restrictions in place.
232: The exact methods are specific to each site and therefore
1.1 deraadt 233: difficult to document here.
