Open TFTP server

[nbirkett]

My ISP is telling me that I have an Open TFTP server on my home network. But, they are unable to provide any more information about which device is involved. My network has an iMac computer, 2 HP printers, iPhone, and a Google Mini as active devices. None should be running a TFTP server.

I have blocked the TFTP server port (69) in my router. A port scan reveals that port 69 is closed.

Does anyone have any pointer as to how I can find out where the problem is? I tried Google without any success.

Thanks.

Of those devices, my bet is either/both of the HP printers.
