Can't run ssb-server on OpenBSD if one interface has IPv6

[rapenne-s]

Hi!

I've run into an issue when running oasis on OpenBSD 6.8 amd64 and arm64, which I've been able to pinpoint down to ssb-server.

If one network interface has an IPv6 assigned, ssb-server will error on start.

I'm not really sure if the issue comes from ssb-server or a dependency. I am not familiar with the JS ecosystem and the errors doesn't make it easy to know where the error is.

Maybe it's from node_modules/ws/lib/WebSocketServer.js but the ws plugin installed in node_modules by npm install downloaded version 1.1.5 of ws which is 3 years old. On the other hand I've run npm test in ssbc/ssb-ws and the test passes fine. I'm quite lost here.

Probably a multiserver issue, not strictly ssb-server

[rapenne-s]

Do you mean this multiserver ?

[hackergrrl]

@rapenne-s Yes, that module.

If you run ssb-server as DEBUG=* node bin.js start do you get any interesting-looking debug messages before Node errors out?

Also: what version of Node are you on?

(I'm low-key wondering if https://github.com/nodejs/node/issues/16712 could be the culprit.)
