This is my first message in this forum. Thank you a lot to everyone for your good advice on forum with guides etc in setting up pool relays and block producers, and all the trouble shooting.
I’ve noticed one of my Relays is experiencing excessive incoming traffic (on the same port as the Cardano node), and this is visible from the Cardano node text graph interface as well. It’s about 30-120 mbytes/sec, but it results in Cardano node requiring periodic excessive cpu usage, despite me adding more resources to the machine.
I am concerned some party is trying to break their way into the relay…for whatever reason, maybe to find out where the block producer is, etc…
At the moment this is looking more like a denial of service/resources on one of my relays. All other relays are behaving normally, without any significant incoming traffic (after having all synchronised etc). Transactions are showing up all well on the relays.
Question: has anyone noticed any similar patterns of strange Incoming traffic towards your relays?
Of course as this traffic is on the same port as the one Cardano node is listening on, I can’t do much about it with the firewall…yet.
