It appears that with all the new vulns being reported in IPMI, Shadowserver has taken up the task of scanning the world again. It appears they have found an IPMI service running on node1.i2u2.org. Running some netflow, this appears to be from a scan they did at 0705.20:14:11 They poked UDP 192.5.186.80 623 via UDP and get a response back. They probed lots of other systems, but only this 1 responded.

Any hope of just killing UDP access from outside on these subnets? In looking at the netflow logs for the past week, it appears the only legit traffic is syslog going to 130.202.172.3 Argonne central server. syslog going to 128.135.125.120 con.ci.uchicago.edu. radius traffic going to auth.mcs.anl.gov:1812 dns traffic to 130.202.101.6 and 130.202.101.37 Why is 192.5.186.65:161 talking to 192.117.188.130 random ports?
