What other common internet noise types do you see?

It is a bit difficult to define "noise", as its definition varies from person to person.

In many cases I would consider the worms of Question2 and the scans of Question3 and Question4 also noise.

In most cases noise is that huge amount of activiy that is not harmful to use if we are not vulnerable to that "something" being exploited (or tried to be).

(check also Question8 in this regard).

Mainly port DstPort138 (name resolution FROM the honeypot in the honeynet and from outside, boxes without a firewall that doesn't do egress filtering, etc)

But also SrcDstPort137 and DstPort139. UDP and TCP.
