title: TFTP fails: server error "unknown option"
body: <p>i am trying to get or put with TFTP protocol. I set the TFPT server and everything worked but stopped working lately. I am able to connect to the server but am getting an error &quot;unknown option -?&quot; when inspecting the Syslog. When running Tcpdump i see the message is &quot;19 RRQ filename netascii&quot;
  i have looked for a couple of days in the net but with no success.</p>
