.TH TFTP 1C "3 July 1985" .SH NAME tftp \- trivial file transfer program .SH SYNOPSIS .B tftp [ host ] .SH DESCRIPTION .I Tftp is the user interface to the Internet TFTP (Trivial File Transfer Protocol), which allows users to transfer files to and from a remote machine. The remote .I host may be specified on the command line, in which case .I tftp immediately establishes a connection to the TFTP server on that host. Otherwise, .I tftp awaits connect instructions from the user. .PP An account or password on the remote machine is not required. Due to lack of authentication information, .I tftp is only able to access publicly readable files. Search permissions of directories leading to accessed files are not checked. .SH COMMANDS Once .I tftp is running, it issues the prompt .B tftp> and recognizes the following commands: .TP \fBconnect\fP \fIhost-name\fP [ \fIport\fP ] Set the .I host (and optionally .IR port ) for transfers. Note that the TFTP protocol, unlike the FTP protocol, does not maintain connections betweeen transfers; thus, the .I 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 .I connect command; the remote host can be specified as part of the .I get or .I put commands. .TP \fBmode\fP \fItransfer-mode\fP Set the mode for transfers; .I transfer-mode may be one of .IR ascii , .IR binary , or .IR mail . The default is .IR ascii . .TP \fBput\fP \fIfile ... destination\fP Put a file or set of files to the specified .IR destination . .I 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. .TP \fBget\fP \fIsource ... file\fP Get a file or set of files from the specified .IR sources . .I 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 .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 .B quit Exit .IR tftp . .TP .B verbose Toggle verbose mode. .TP .B trace Toggle packet tracing. .TP .B status Show current status. .TP \fBrexmt\fP \fIretransmission-timeout\fP Set the per-packet retransmission timeout, in seconds. .TP \fBtimeout\fP \fItotal-transmission-timeout\fP Set the total transmission timeout, in seconds. .TP \fB?\fP \ [ \fIcommand-name\fP ... ] Print help information. .SH BUGS .PP The .I verbose command has no effect.
