Strange network probes on UDP port: 161
Ever since I have brought my new system on line I have been getting the
following reports from other server:
Jan 4 20:47:49 maps portsentry: attackalert: Connect from host:
192.168.1.113/192.168.1.113 to UDP port: 161
Jan 4 20:47:49 maps portsentry: attackalert: Host: 192.168.1.113
is already blocked. Ignoring
Since all these systems are behind a firewall device and my local
network is all configured on the 10.1.1.x network this is a little
strange. I'm pretty sure it is coming from the new hardware, but I'm not
sure how to confirm it other than to turn off the new server and see if
the messages stop.
I do have an IPMI card in the new server that I have not figured out how
to setup and configure because I have been focused on other issues first.
port 161 is an snmp port but I can find no reference to anything like
that in the motherboard user's guide for the SuperMicro X6DHT-G motherboard.
Any thoughts on this?
