comment Windows 7 Requires ARP for UDP?
embedded systems, not under my control, probably not running an operating system, just acting as TFTP clients downloading a file at startup from a pre-configured TFTP server IP address

@cpt_fink that's right, Windows 7 doesn't register a new ARP entry (or update an existing one) on the initial RRQ (as insane as that sounds)

comment Windows 7 Requires ARP for UDP?
unfortunately, I can't presume the MAC address at a given IP address is always the same... that is to say, the computer I plug into a given port always gets the same IP address (statically assigned), but I plug in different computers (with different MAC addresses) into that port

if all you ever do is respond to messages, you can get the destination MAC from the incoming packet...

comment Strange UDP/TFTP Problem
So, it turns out that if I just retry more times (10 is the magic number apparently, I was using 5), Tftpd32 eventually does establish the connection and all is well with the world. Why the heck is the connection established with zero retries when I'm watching in wireshark?

I can confirm that wireshark running on a third party machine (not involved in the transaction) sees the client packets, but the TFTP server remains unresponsive.

comment Strange UDP/TFTP Problem
@andycjw interesting point, so when wireshark is running my network card is configured differently and Tftp32d "inherits" that configuration... What's different about the traffic I'm generating that causes it to get through to the server only if the NIC is in promiscuous mode?

I am writing the TFTP client code... don't close this question on the premise that I'm asking how to use software
