[HECnet] netowrk flapping....

[Peter Lothberg]

I see these message about every 20 minutes from random nodes.   The error
message is almost always:
"Unexpected packet type"

A: Something is corrupting the packet, or they are out of order or a
packet disapeared.

B: Someone is sending packets to you that looks like Multinet Decnet,
but not one of your "peers".

So where do we go from here?

We need more information, and if we can se a pattern. 

A: Is there any Multinet link that is stable?
B: Is it related to a site?

If we could do TCPDUMP on this wire with NTP based timestaps on both
sides, we can se what get's corrupted or disappears?
