[warning] Failed to connect to "/p2p/...": dialing_self about erlang-libp2p HOT 5 CLOSED

nevermind I probably need to add a stream handler first. what shoul dI expect if the stream handler is created a connection is set?

from erlang-libp2p.

Hmm.. you'll need to create a stream handler to do anything useful with a session, but you should be able to connect two swarms together without any custom handlers.

I'm not sure what's wrong here since the unit tests do exactly this setup, but here's a couple of things to try:

1. Could you check on the filesystem to ensure that each swarm had a unique data folder?
2. Try setting the peerbook_connections option to 0 to see if that's what's causing the problem.

Add the following tuple to the startup opts:

{ libp2p_group_gossip, [{peerbook_connections, 0}] }

sorry I missed your answer. I will try later today. To be honest I wouldn't be against a quick and dirty "getting started" doc :)

why do they need a data folder btw?

from erlang-libp2p.

A swarm stores its keys in the data folder (unless configured otherwise) as well as it's peer book and any group information that has to persist across restarts/crashes
