Thus spake Bruce Campbell" <bc-nanog@vicious.dropbear.id.au>
Introducing new devices that are intended to trust that big, bad, easily spoofable internet using non-secured protocols such as tftp in order to get their configuration from a non-local server shows a degree of trust not seen since the Famous Five, the BabySitters Club and pre '96 O'Reilly books on writing internet protocols.
Unfortunately, TFTP is the only protocol that many phone vendors implement -- and VoIP operators aren't happy about it. Some vendors have started implementing HTTP(S), but it's far from common at this point. S Stephen Sprunk "Stupid people surround themselves with smart CCIE #3723 people.
