NAME

tftp - trivial file transfer program

SYNOPSIS

tftp [ host ]

DESCRIPTION

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 host may be specified on the command line, in which case tftp uses host as the default host for future transfers (see the connect command below).

USAGE

Once tftp is running, it issues the prompt tftp> and recog- nizes the following commands: Commands connect host-name [ port ] Set the host (and optionally port) for transfers. The TFTP protocol, unlike the FTP protocol, does not main- tain connections between transfers; thus, the 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 connect command; the remote host can be specified as part of the get or put commands. mode transfer-mode Set the mode for transfers; transfer-mode may be one of ascii or binary. The default is ascii. put filename put localfile remotefile put filename1 filename2 ... filenameN remote-directory Transfer a file, or a 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: host:filename to specify both a host and filename at the same time. If the latter form is used, the specified host becomes the default for future transfers. If the remote- directory form is used, the remote host is assumed to SunOS 5.8 Last change: 16 Jun 1999 1 User Commands tftp(1) be running the UNIX system. The host can be a host name (see hosts(4) or ipnodes(4)) or an IPv4 or IPv6 address string (see inet(7P) or inet6(7P)). Since IPv6 addresses already contain ":"s, the host should be enclosed in square brackets when an IPv6 address is used. Otherwise, the first occurence of a colon will be interpreted as the separator between the host and the filename. For exam- ple, [1080::8:800:200c:417A]:myfile Files may be written only if they already exist and are publicly writable. See in.tftpd(1M). get filename get remotename localname get filename1 filename2 filename3 ... filenameN Get a file or set of files (three or more) from the specified remote sources. 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: host:filename to specify both a host and filename at the same time. If the latter form is used, the last host specified becomes the default for future transfers. See the put command regarding specifying a host. quit Exit tftp. An EOF also exits. verbose Toggle verbose mode. trace Toggle packet tracing. status Show current status.

NOTES

The default transfer-mode is ascii. This differs from pre- SunOS 4.0 and pre-4.3BSD systems, so explicit action must be taken when transferring non-ASCII binary files such as exe- cutable commands. Because there is no user-login or validation within the TFTP protocol, many remote sites restrict file access in various ways. Approved methods for file access are specific to each site, and therefore cannot be documented here. When using the get command to transfer multiple files from a remote host, three or more files must be specified. If two files are specified, the second file is used as a local file.
