Why do you always have problems with TFTP to transfer things? 20

TFTP is an FTP upload software, XP system comes with, but only the command line does not have a graphical interface, you can open the command line to enter TFTP to run will help.

There is special software, and it seems that there is also its own under DOS. It means fast transfer of small files.

TFTP: Simple File Transfer Protocol.

tftp：trivial file transfer protocol)

Simple File Transfer Protocol is a simple protocol for transferring files that runs on UDP (User Datagram Protocol). TFTP is designed to be small, simple and easy to operate, and as such, it lacks many of the features of the standard FTP protocol. TFTP can only read and write files (e-mail) from a remote server or send files to a remote server.

It can't list directories and doesn't currently provide user authentication.

Currently, TFTP has 3 transmission modes: netASC11 mode, i.e. 8-bit ASC11; octet mode (which replaces the binary mode of previous versions), such as the original octet; Mail mode, in which characters are transferred not to the user. Other modes can be defined by the hosts.

In the TFTP protocol, any transfer process starts with a request to read and write a file, and at the same time establishes a connection. If the server agrees to the request, the connection is successful and the file is delivered in a fixed 512-byte block. Each packet contains a block of data that must be acknowledged by an acknowledgment response packet before the next packet can be sent.

Packets with less than 512 bytes illustrate the end of the transmission. If a packet is lost in the network, the receiver times out and resends its last packet (either data or acknowledgment response), which causes the sender of the lost packet to resend the missing packet. The sender needs to keep a packet on hand for resending, because the lock acknowledgment response guarantees that all past packets have been received.

Note that both parties to the transmission can be seen as both the sender and the receiver. One party sends the data and receives an acknowledgement response, and the other party sends an acknowledgement response and accepts the data.

The mapping that follows is also a must.

Enter cmd in the start of the run, enter the dos, and enter tftp

If there is a TFTP >; It's just to start the addition of I don't understand Q remember to adopt.

c:\users\dell>tftp

Files are transferred to or from a remote computer running the TFTP service.

tftp [-i] host [get | put] source [destination]

i Specifies the binary image transfer mode (also known as octal). In binary image mode, byte by byte.

Move files. Use this mode when transferring binary files.

host specifies a local or remote host.

get transfers the file destination on the remote host to the file source on the local host.

PUT transfers the file source on the local host to the file destination on the remote host.

source specifies the files to be transferred.

destination specifies the location to which you want to transfer the file.

c:\users\dell>tftp get kernel kerneldown

Successful transfer: 7 seconds 3569899 bytes, 509985 bytes seconds.

Go to the next TFTP server software on the Internet, after installation, the software settings folder tftp directory, generally there is a client test file, run the test on other computers OK, the router upgrade file is placed in the tftp directory, and then specify the IP address of the TFTP server.

First, install a TFTP server software on your computer.

First of all, the next TFTP server, generally all kinds of firmware will come with it. This one can be found under my csdn, free of points.

The first line in this means that the home directory of the face-to-face TFTP is this, the second line in this is the listening IP address of the current server, the first label of the TFTP server is the log of the current server, click on the following setting and then pop-up window, the main setting options are only the port of TFTP, the default directory of TFTP, and whether the DHCP service is enabled.

DHCP is mentioned here. Some routers or other embedded devices allow the use of "HyperTerminal" connection during the flashing process, but there is no IP address, and the IP address cannot be set, so you need to open the DHCP server to connect to the embedded device.
