How to disconnect a node/peer

In looking through my peerinfo I have a node who is not updating their blockchain header. Is there a way for me to disconnect a node and get another connection?

Fooled around with
addnode ip:port remove

and get the error
node has not been added

tried adding and then removing, no error messages but the node was still attached.

try tcp kill. you can see the peer and port. compare with getpeerinfo to be sure which one to send to kingdomcome. :slight_smile:

I started adding IP addresses to the firewall to be blocked. This worked. The node connection would drop and a new peer node would be added. I added @ 30 ip addresses, but continued getting addresses that were very slow at updating their block header. Then decided to just let the network correct. I deleted all those firewall rules and opened it back up because I don’t know if the network would consider my node a bad performer.

I’ve been searching on the web for answers about how the node network works with bitcoin. But haven’t found any great answers yet.

  • Are there any disadvantages for the network if I block IP addresses?

  • If a peer node is not updating their block headers, how does that affect the network?

  • How much intelligence is in the zcash node network for low performing or misbehaving nodes?
