C Installing and Using TFTP

Overview: What Is TFTP?

TFTP, the Trivial File Transfer Protocol, allows the HP TopTools Remote Control card to access boot floppy images and new firmware images stored at a LAN or modem-connected computer. TFTP is built on top of TCP/IP and is functionally a subset of FTP. As its name indicates, this protocol is used to transfer data between a "TFTP server" and either the HP TopTools Remote Control or some other device that acts as the "TFTP client."

NOTE

TFTP and the HP TopTools Remote Control card depend on

 

the TCP/IP protocol. If you are able to view the HP TopTools

 

Remote Control user interface on your remote computer, this

 

protocol is already functioning correctly. If not, modification

 

of either your browser or networking environment may be

 

required.

 

 

HP TopTools Remote Control uses the TFTP service to:

∙Access boot floppy images that allow administrators to help diagnose HP NetServer problems and update the server BIOS.

∙Update HP TopTools Remote Control firmware.

TFTP file transfer consists of client-side and server-side components. Because the HP TopTools Remote Control card has the client TFTP service built into its firmware, you can use TFTP to transfer either firmware images or boot images from either a local or a remote computer running a TFTP server program, see Figure C-1.
