Re: scans on ports 3072 and 1024, why?

I thought this was probably the case.  In capturing the traffic
to<->from dalnet.away.net, there was nothing originating from my net.
It seemed reasonable that someone was using mine and others networks as
spoofed source addresses to which dalnet.away.net was responding with
RST's.  Nice to have confirmation (and correlation).

Sean,
These hosts (dalnet.away.net and atleast one other dalnet server) were
being heavily ack flooded until about 9am yesterday... the 'scans' you
were seeing were RESET's from the IRC servers... :) It also confused me as
I thought I was seeing some new network mapping system in action.
