Just wondering if anyone knows whether TFTP cares what the src/dst IP address of a request/response is? Does it only listen on the UDP port and ignores the IP addresses on the packets?

I ask because when I use WindowsXP DOS tftp command, looking in the packet sniff I'm getting errors like : "This program cannot be run in DOS" and "Sorry, wasn't talking to you". In my scenario with a loadbalancer, the src/dest IP's get changed.

When I use TFTPD32 as my client... the GET works no problem... even when the tftp response came from an IP address that the client did not originally send a request to.

"Sorry, wasn't talking to you"

This is VERY interesting for a seemingly completely unrelated topic:

Knowing how much the guys at MS like to "re-cycle" code, it is possible that a copy of TFTP is embedded in SETUPLDR.BIN.

Thanks! (IMG:../forums/style_emoticons/default/thumbup.gif)
