Hey gang, I saw a post on Twitter about some knots nodes being targeted with a DDOS attack to spam a node for repeated IBD requests. The node was able to view, filter, and whitelist/blacklist their connected peers using an alternative node software from Start9. I tried poking around in the Bitcoin/Knots service tab and saw that under “Properties” I can view how many peers are currently connected, but I can’t do anything like boot, block, or view info on them. It made me think that this would be a good feature to add. Who would be able to implement this?
The good news is, this peer cannot connect to you over clearnet, because on StartOS Bitcoin can only be connected to over tor. If you have not disabled clearnet, your server chooses which nodes to connect to. The interface shown in the X post, is not StartOS. If you want to, in the config, under advanced>peers, you can disable make public, and peer discovery, then manually designate the peers you want to connect to. There is no peer blocklist available in the config interface. This would be best done in your router/firefall.
