10 | tftp \- trivial file transfer program | |
11 | .SH SYNOPSIS | |
12 | .B tftp | |
13 | [ | |
14 | host | |
15 | ] | |
16 | .SH DESCRIPTION | |
17 | .I Tftp | |
18 | is the user interface to the Internet TFTP | |
19 | (Trivial File Transfer Protocol), | |
20 | which allows users to transfer files to and from a remote machine. | |
21 | The remote | |
22 | .I host | |
23 | may be specified on the command line, in which case | |
24 | .I tftp | |
25 | uses | |
26 | .I host | |
27 | as the default host for future transfers (see the | |
28 | .B connect | |
29 | command below). | |
30 | .SH COMMANDS | |
31 | Once | |
32 | .I tftp | |
33 | is running, it issues the prompt | |
34 | .B tftp> | |
35 | and recognizes the following commands: | |
36 | .TP | |
37 | \fBconnect\fP \fIhost-name\fP [ \fIport\fP ] | |
38 | Set the | |
39 | .I host | |
40 | (and optionally | |
41 | .IR port ) | |
42 | for transfers. | |
43 | Note that the TFTP protocol, unlike the FTP protocol, | |
44 | does not maintain connections betweeen transfers; thus, the | |
45 | .I connect | |
46 | command does not actually create a connection, | |
47 | but merely remembers what host is to be used for transfers. | |
48 | You do not have to use the | |
49 | .I connect | |
50 | command; the remote host can be specified as part of the | |
51 | .I get | |
52 | or | |
53 | .I put | |
54 | commands. | |
55 | .TP | |
56 | \fBmode\fP \fItransfer-mode\fP | |
57 | Set the mode for transfers; | |
58 | .I transfer-mode | |
59 | may be one of | |
60 | .IR ascii | |
61 | or | |
62 | .IR binary . | |
63 | The default is | |
64 | .IR ascii . | |

72 | \fBput\fP \fIfile1 file2 ... fileN remote-directory\fP | |
73 | Put a file or set of files to the specified | |
74 | remote file or directory. | |
75 | The destination | |
76 | can be in one of two forms: | |
77 | a filename on the remote host, if the host has already been specified, | |
78 | or a string of the form | |
79 | .I host:filename | |
80 | to specify both a host and filename at the same time. | |
81 | If the latter form is used, | |
82 | the hostname specified becomes the default for future transfers. | |
83 | If the remote-directory form is used, the remote host is | |
84 | assumed to be a | |
85 | .I UNIX | |
86 | machine. | |

95 | Get a file or set of files from the specified | |
96 | .IR sources . | |
97 | .I Source | |
98 | can be in one of two forms: | |
99 | a filename on the remote host, if the host has already been specified, | |
100 | or a string of the form | |
101 | .I host:filename | |
102 | to specify both a host and filename at the same time. | |
103 | If the latter form is used, | |
104 | the last hostname specified becomes the default for future transfers. | |

134 | .SH BUGS | |
135 | .PP | |
136 | Because there is no user-login or validation within | |
137 | the | |
138 | .I TFTP | |
139 | protocol, the remote site will probably have some | |
140 | sort of file-access restrictions in place. The | |
141 | exact methods are specific to each site and therefore | |
142 | difficult to document here. |
