Connecting to Mina Bootstrappers

[dennis-tra]

Hi everyone, I'm trying to connect to Mina's bootstrappers listed here: https://storage.googleapis.com/mina-seed-lists/mainnet_seeds.txt

As far as I understand, Mina is using libp2p and also the libp2p DHT implementation. My assumption was that the bootstrappers are also libp2p hosts. I could be totally wrong though.

Anyway, I'm trying to connect like this:

package main

import (
	"fmt"

	"github.com/libp2p/go-libp2p"
	"github.com/libp2p/go-libp2p/core/peer"
	"github.com/libp2p/go-libp2p/p2p/muxer/yamux"
	"golang.org/x/net/context"
)

func main() {
	addrInfo, err := peer.AddrInfoFromString("/dns4/mina-seed.etonec.com/tcp/8302/p2p/12D3KooWKQ1YVtqZFzxDmSw8RASCPZpDCQBywnFz76RbrvZCXk5T")
	if err != nil {
		panic(err)
	}

	h, err := libp2p.New(
		libp2p.UserAgent("github.com/codaprotocol/coda/tree/master/src/app/libp2p_helper"),
		libp2p.Muxer("/coda/yamux/1.0.0", yamux.DefaultTransport),
	)
	if err != nil {
		panic(err)
	}

	fmt.Println("Connecting...")
	err = h.Connect(context.TODO(), *addrInfo)
	fmt.Println(err)
}

But this gives me varying errors along failed to negotiate security protocol: incoming message was too large.

What am I doing wrong? Does the libp2p host need to be configured differently or are these bootstrappers not libp2p nodes? Where can I find the list of bootstrappers for the DHT?
