Node: multiple ipv6 request not working

With curl it works:

root@server:~/server-scripts# curl --interface enp1s0 https://v6.ident.me/ && echo && echo
2001:470:1f1b:5b5:9ade:d0ff:fe04:23c3

root@server:~/server-scripts# curl --interface enp2s0 https://v6.ident.me/ && echo && echo 
2001:470:1f1b:5b3:eeaa:a0ff:fe1b:4d84

With Nodejs, just one request, it works:

/* The request
{ url: 'https://v6.ident.me/.json',
  localAddress: '2001:470:1f1b:5b3:eeaa:a0ff:fe1b:4d84' }
*/

 utils.http.request(getRequest({
                    url: 'https://v6.ident.me/.json',
                    //family: 6,
                    localAddress: getIpV6(interfaces.enp2s0).address
                })),

result:

{ address: '2001:470:1f1b:5b3:eeaa:a0ff:fe1b:4d84' }

With 2 request, it is stuck:

/* 2 Request - 2 different functions
{ url: 'https://v6.ident.me/.json',
  localAddress: '2001:470:1f1b:5b3:eeaa:a0ff:fe1b:4d84' }
{ url: 'https://v6.ident.me/.json',
  localAddress: '2001:470:1f1b:5b5:9ade:d0ff:fe04:23c3' }
*/

I get no results. If i change 2nd with IPV4, it works of works.

Can you post a complete test case with no third-party dependencies? I.e., no dependencies on npm packages.

The error :-1: 

{ message: 'connect ETIMEDOUT 2a01:7e00::f03c:91ff:fe70:2b9d:443',
  stack: 'Error: connect ETIMEDOUT 2a01:7e00::f03c:91ff:fe70:2b9d:443\n    at Object.exports._errnoException (util.js:1016:11)\n    at exports._exceptionWithHostPort (util.js:1039:20)\n    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1138:14)' }

No idea where this 2a01:7e00::f03c:91ff:fe70:2b9d:443' comes from. But it is a NodeJs issue, because I have to revert to curl for now.

there is no thrid party dependencies, a simple request, a wrapper. pure node request.

p3x-robot picture p3x-robot on 19 Jun 2017

Then please post that complete test case I asked for. If I can't run it, I'm not going to look at it.

You can see, the 2nd interface is not working wiith NodeJs, but everywhere it is working wget and curl.

Here are the interfaces, but it is only with NodeJs. C, PHP works.

```

thanks for helping!

Seems to be working for me locally. Does it make a difference if you pass in a link-local address, like 2001:470:1f1b:5b3:eeaa:a0ff:fe1b:4d84%enp2s0? (Note the %enps20 suffix.)

Ciao!
How are you?
Do you have 2 interfaces? I use 2 interfaces for the server. How do you make it to work with NodeJS?
I tested, but the same result. And only with NodeJs. PHP is good. Look the settings. they seem good.

Code:'

#!/usr/bin/env node
const os = require('os');
const https = require('https');
const url = require('url');
const exec = require('child_process').exec

const interfaces = os.networkInterfaces();
delete interfaces.lo;

console.log('interfaces')
console.log(interfaces);

const parsedUrl = url.parse('https://v6.ident.me/.json');

Object.keys(interfaces).forEach(_interface => {
    const curlUrl = `curl -ssk --interface ${_interface} https://v6.ident.me/.json`;
    console.log()
    console.log('CURL', curlUrl);
    exec(curlUrl, (err, stdout, stderr) => {
        console.log();
        console.log(`CURL RESULT ${_interface} err`, err)
        console.log(`CURL RESULT ${_interface} stdout`, stdout)
        console.log(`CURL RESULT ${_interface} stderr`, stderr)
    });

    const ipv6 = interfaces[_interface].find(info => {
        return info.family === 'IPv6' && !info.address.startsWith('f');
    });
    const httpRequest = Object.assign({
        localAddress: `${ipv6.address}%${_interface}`,
        family: 6,
    }, parsedUrl);

    Object.keys(httpRequest).forEach((key) => (httpRequest[key] == null) && delete httpRequest[key]);

    console.log();
    console.log('NODE Request', httpRequest);
    const req = https.get(httpRequest, (res) => {
        res.on('data', (chunk) => {
            console.log();
            console.log(`NODE RESULT ${ipv6.address}` + '%%' + `${_interface}`, chunk.toString());
        });
    })
    req.end();
})

Result;

There is a timeout, I waited, but I have no idea this IPv6 address comes, because it only with NodeJs.
Do you know how can do it? The routes are good, nothing like that anywere.
PHP, CURL, working.

p3x-robot picture p3x-robot on 19 Jun 2017

Yes, two interfaces. I didn't need to do anything special (except use the right interface names), it just worked.

Perhaps try strace'ing node and curl to see what they do differently. Look for bind, connect, ioctl, setsockopt, etc. system calls. If I had to venture a guess, it's that curl binds to the interface (with an ioctl) while node binds to the address.

bnoordhuis picture bnoordhuis on 20 Jun 2017

I'm going to close this for now because so far it seems to be an issue with your local environment. I can reopen if it does turn out to be a bug in node.

If you want to debug this further, open an issue over at https://github.com/nodejs/help/issues and we'll take it from there.

bnoordhuis picture bnoordhuis on 20 Jun 2017

can you show works with 2 interfaces? you code, please! where i am doing something wrong and you already got it.

p3x-robot picture p3x-robot on 20 Jun 2017

please you are using 2 ipv6, 1ipv6 works, it is deffirent ndoejs error, since with work it works!
how can my entirvonrnemt bad is everything works (mail server, https,)
only in nodejs not working with 2 ipv6 adress.
curl works!!!
why is my entinvornment bad!!!!
this weird!

p3x-robot picture p3x-robot on 20 Jun 2017

The only changes I made to your script were the interface names.

bnoordhuis picture bnoordhuis on 20 Jun 2017

i see, end nodejs cannot select the interface? only bind to an address?

p3x-robot picture p3x-robot on 20 Jun 2017
😕1

Correct. Node calls bind(2). I suspect curl calls an ioctl or setsockopt(SO_BINDTODEVICE).
