Describe the bug

error: [noia-contents-client] uncaughtException: Port should be > 0 and < 65536.

To Reproduce Steps to reproduce the behavior:

1. Fresh Ubuntu 16.04 LTS installation
2. installed nodejs 10.09
3. https://github.com/noia-network/noia-node-cli/
4. cd noia-node-cli && npm install && npm run build && npm start
5. configure ~/.noia-node-cli/settings.json with wallet address, public IP
6. npm start
7. wait some minutes until the error arises

Update

1. Uninstalled nodejs v10.09 & installed nodejs v8.4.11 LTS
2. Uninstalled previous global version: $ npm uninstall @noia-network/node-cli -g
3. Installed new version: $ npm install @noia-network/node-cli -g --unsafe-perm
4. Started global node version: $ noia-node-cli
5. Wait

Error

dgram.js:419
    throw new errors.RangeError('ERR_SOCKET_BAD_PORT');
    ^

RangeError [ERR_SOCKET_BAD_PORT]: Port should be > 0 and < 65536
    at Socket.send (dgram.js:419:11)
    at Socket.server.on (/usr/lib/node_modules/@noia-network/node-cli/node_modules/@noia-network/webrtc-direct-server/dist/udp-proxy.js:96:25)
    at emitTwo (events.js:126:13)
    at Socket.emit (events.js:214:7)
    at UDP.onMessage [as onmessage] (dgram.js:659:8)

Edit When testing the connection with:

const WebRtcDirect = require("@noia-network/webrtc-direct-client");
const wrtc = require("wrtc");

const address = "http://**removed**:8048";
const client = new WebRtcDirect.Client(address, {
    wrtc: wrtc
});

async function main() {
    try {
        console.log("connecting...");
        await client.connect();
        console.log("stopping...");
        await client.stop();
        console.log("exiting...");
        process.exit();
    } catch (err) {
        console.error("error", err);
    }
}

main();

the above error arises. Printing des in udp_proxy.js line 95 yields my IPv6 loopback address e.g.: ::2:40605 which results in destPort and destIP being set to 0 and therefore throwing the exception.

Quick Fix Remove IPv6 adapters with: $ sysctl -w net.ipv6.conf.all.disable_ipv6=1 $ sysctl -w net.ipv6.conf.default.disable_ipv6=1

Conclusion IPv6 support must be implemented in the future or ignore IPv6 adapters in webrtc-direct.js implementation.
