I'm playing around with connecting my node to another one of my nodes to see how many incoming connections I can handle.
Whenever I add node A from node B with
bitcoin-cli addnode 184.108.40.206 add after the first time, I get:
error code: -23
Error: Node already added
Is there a way around this? Can I edit the source code somehow to allow multiple connections between the same nodes? Presumably I would only have to edit the code for the sending node, not the receiving node, since I think the receiving node has to be able to accept connections from what appear to be the same IP and port because of NATS? The alternative is to run many instances of bitcoind in pruned mode which would work I guess, but it's not ideal obviously
