The remote .I host may be specified on the command line, in which case .B tftp uses .I host as the default host for future transfers (see the .B connect command below.) .SH OPTIONS .TP \fB\-c\fP \fIcommand\fP Execute \fIcommand\fP as if it had been entered on the tftp prompt. Must be specified last on the command line. .TP \fB\-m\fP \fImode\fP Set the default transfer mode to \fImode\fP. This is usually used with \-c. .TP .B \-v Default to verbose mode. .TP .B \-V Print the version number and configuration to standard output, then exit gracefully. .SH COMMANDS Once .B tftp is running, it issues the prompt \f(CWtftp>\fP and recognizes the following commands: .TP \fB?\fP \fIcommand-name...\fP .TP \fBhelp\fP \fIcommand-name...\fP Print help information .TP .B ascii Shorthand for .BR "mode ascii" . .TP .B binary Shorthand for .BR "mode binary" . .TP \fBconnect\fP \fIhost [port]\fP Set the .I host (and optionally .IR port ) for transfers. Note that the TFTP protocol, unlike the FTP protocol, does not maintain connections between transfers; thus, the .B 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 .B connect command; the remote host can be specified as part of the .B get or .B put commands. .TP \fBget\fP \fIfile\fP .sp -.6l .TP \fBget\fP \fIremotefile localfile\fP .sp -.6l .TP \fBget\fP \fIfile1 file2 file3...\fP Get a file or set of files from the specified sources. A remote filename can be in one of two forms: a plain filename on the remote host, if the host has already been specified, or a string of the form .I "host: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. .TP \fBmode\fP \fItransfer-mode\fP Specify the mode for transfers; .I transfer-mode may be one of .B ascii (or .BR netascii ) or .B binary (or .BR octet .) The default is .BR ascii . .TP \fBput\fP \fIfile\fP .sp -.6l .TP \fBput\fP \fIlocalfile remotefile\fP .sp -.6l .TP \fBput\fP \fIfile1 file2 file3... remote-directory\fP 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 .I "host: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 UNIX system or another system using .B / as directory separator. .TP .B quit Exit .BR tftp . End-of-file will also exit. .TP \fBrexmt\fP \fIretransmission-timeout\fP Set the per-packet retransmission timeout, in seconds. .TP .B status Show current status. .TP \fBtimeout\fP \fItotal-transmission-timeout\fP Set the total transmission timeout, in seconds. .TP .B trace Toggle packet tracing (a debugging feature.) .TP .B verbose Toggle verbose mode. .SH "NOTES" The TFTP protocol provides no provisions for authentication or security. Therefore, the remote server will probably implement some kinds of access restriction or firewalling. These access restrictions are likely to be site- and server-specific. .SH "AUTHOR" This version of .B tftp is maintained by H. Peter Anvin . It was derived from, but has substantially diverged from, an OpenBSD source base, with added patches by Markus Gutschke and Gero Kulhman. .SH "SEE ALSO" .BR tftpd (8).
