We saw this too, and we were lucky enough, by sniffing upstream in the
network, to trace it back to one of our ResNet users. We shut off the
student's port and we told our ResNet folks to go clean up the machine. It
got cleaned up and turned back on. Sadly, I can't tell you more specifically
what the cause was.

   We are forcing Snort to listen to one real port only with the -i option,
and we're also seeing a *lot* of packets with a source of
This was confirmed by one of our network guys who plugged another packet
sniffer into the Snort port.  This seems to be real traffic, and we're
baffled by the source.
