    My init does a Set Time from the network; right in the middle,
    it did this:

    New time is 6/27/91 23:49:59.
    [23:50:17 IP Error 3 3:  IP E->A     3 (0:12)
		UDP[   37 1026] length 12: AC 15 2F AA  ,/*]
     Set status line time? (Y or N)


    Any ideas? Some wierd animal.

You shouldn't see "IP Error" notifications unless you've set
TCP:*IP-DEBUG-FLAG*.

Error 3/3 is Port Unreachable, which is sent by hosts when they receive
a UDP datagram to an unrecognized port.

I think what happened here is that E was slow in responding to A's
broadcast query for the time, so its response came after A had already
closed the reply port.  It therefore treated the reply as if it were a
query to an unrecognized server port.  This confusion is an unfortunate
consequence of the symmetricity of the UDP protocol -- there's no
inherent way to distinguish queries from responses.
