TFTP and FTP works much the same ???
They serve to the same purpose : to transfer files over net but thei are pretty much different !
TFTP is a very very simple one !
I agree on that TFTP is encapsulated in UDP and FTP it uses TCP and i know pretty much the difference. (no offence).
I read a lot of documents about protocols this time now and what i did not found on any of those was something regardind the maximum size of a file trasferred using TFTP witch is 31.9 Mb !
TFTP it uses fixed size blocks of 512 bytes !
It also uses a field in the header called "Block #" witch is 2 bytes number ( 65536 values)
Value 0 is used for acknowledgment so it remains 65535 posible values ! If you multiply 65535 and 512 it comes out that the maximum size of a file trasfered using TFTP is 33553920 bytes !
If you try to send any file bigger than that value it will fail !
read the RFC0783 and RFC1350 ! is nothing there about this !
Anyway thank you again !
