Subject: [Snort-users] Strange PATH MTU Traffic
I am getting this alert: ICMP PATH MTU denial of service
I have never had this alert previous to this weekend, and have received
40,000 within the last 8 hours. Some of this traffic appears to be
encrypted, the rest of it is hitting our domain controllers and contains
schema information.
I know Microsoft does some screwy stuff but I have never seen schema
information transmitted in an ICMP packet, much less a path mtu discovery
packet.
Anyone else seen this type of traffic?
