While looking through my node’s log, I see an untrusted node attempting to initiate communication.
The node ID:
1QzDKGHDeyuRxbvZhcwHU3syxTYtU1jHy5duAKuPxja3XC8ttk appears in other posts on this forum. So, I assume that this particular node is free running and/or not carefully monitored by the operator.
As I understand the identity process… each node since 17 includes a signed x509 cert as a trust root… called the node’s “identity”… So, the above listed untrusted node must be missing its signed x509 cert. Is that correct?
Also when I check this node on Storjnet I don’t see any uptime information, just that the GeoIP seems to be Paris, France.
So, what protections, if any, are there against an untrusted node DDoS-ing the network with numerous rejected requests? And, is there any method that a node operator may protect against such by dropping packets from the offending incoming IP address?
