That depends on what you want to do. Do you understand the differecne between TFTP and BOOTP (resp. DHCP) protocols?
I understand tftp and bootp as a function of current DHCP, but I don't know how tftp and bootp is related. Would you suggest me something to read? Thank you.
Bootp is a boot protocol that allows a system to query a server to figure out what IP it is assigned and what executable file to load (typically via TFTP). DHCP is the successor to bootp.
TFTP is a file transfer protocol that allows a system to load its executable (typically) file from the server.
