linksys has changed a bit the tftp protocol; not much, they just
included some kind of authentication, i forgot what exactly, but try
this: http://www.volny.cz/oldfrog/tftp/linksys-tftp.tar.bz2

(i have used _some_ linksys-tftp program with success some time back.
i cannot swear this was the exact one, but it looks identical enough).
