Investigation is still ongoing, but from what they can tell, majority of the attempted connections have been going over TCP port 22. -jack -----Original Message----- From: Josh Duffek [mailto:consultantjd16 () ridemetro org] Sent: Friday, October 01, 2004 11:05 AM To: Jack Vizelter; nanog () merit edu Subject: RE: Internet Connectivity Did you run a sniffer to get an idea of what all the traffic is? Curious what, if any, port(s) are being flooded.

We had no traffic coming in or out of the campus. We're unsure of whether it's virus related, but wanted to inquire if anyone else has heard of or came across something similar. It appears to be an DDOS attack, but, originating from the inside. This started last night at about 10pm EST. Thanks, -jack
