Install extension with HTTP Proxy with Basic authentification not working

[ovidiubuligan]

Hello,
trying to use proxy settings with basic authentification http://user1:mypa$$1@proxy1.company.com:3128 results in errors .

Looking into dev tools I see entries similar to this one:

connect EAFNOSUPPORT 10.0.1.1:3128 - Local (undefined:undefined): Error: connect EAFNOSUPPORT 10.0.1.1:3128 - Local (undefined:undefined)
    at Object.exports._errnoException (util.js:837:11)
    at exports._exceptionWithHostPort (util.js:860:20)
    at connect (net.js:838:14)
    at net.js:981:7

/C:/Program Files (x86)/Microsoft VS Code/resources/app/out/vs/workbench/workbench.main.js:27 WARNING: Promise with no error callback:7

other programs that use http_proxy/https_proxy environment variables work with the current env settings(ex curl).
Does someone have a clue?

What do you get if you run node and in its interactive prompt run require('url').parse('YOUR PROXY URL')?

Namely, do the host and auth parameters look OK to you?

If not, you might need to url escape your username / password.

[ovidiubuligan]

I have node 4.3.1 in windows 7 with vs code 10.10 and I get :

Url {
  protocol: 'http:',
  slashes: true,
  auth: 'user1:pa$$1',
  host: 'proxyhost.company.com:3128',
  port: '3128',
  hostname: 'proxyhost.company.com',
  hash: null,
  search: null,
  query: null,
  pathname: '/',
  path: '/',
  href: 'http://user1:pa%24%241@proxyhost.company.com:3128/' }

I have
Also running with code 10,08 same problem .

[joaomoreno]

Is there any functionality that seems broken? Can you for example install extensions?

[ovidiubuligan]

That is where I get the error , trying to install an extension , in the autocomplete listing.
I also have multiple network interfaces from vagrant and OpenVPN . I have no ideea where to start looking at.

I also have another funky network related application: http://widecap.com/ , It can make any application proxyfiable even if it doesn't support poroxying .I use it for apps that don't support proxying.I also tried widecap on vscode without proxy ... but I got some other errors in the console.

[joaomoreno]

The error code EAFNOSUPPORT is what gets me worried. There's something about your system that doesn't let Code talk to 10.0.1.1:3128, which looks like a decently normal IPv4 address to me.

Is 10.0.1.1 your proxy?

[ovidiubuligan]

Ns lookup on the proxy host gives me 10.0.1.1.

I tried again with *_widecap *_software and the error I get is :

connect EAFNOSUPPORT **1.0.0.1:443** - Local (undefined:undefined): Error: connect EAFNOSUPPORT 1.0.0.1:443 - Local (undefined:undefined)
    at Object.exports._errnoException (util.js:837:11)
    at exports._exceptionWithHostPort (util.js:860:20)
    at connect (net.js:838:14)
    at net.js:981:7
    at GetAddrInfoReqWrap.asyncCallback [as callback] (dns.js:62:16)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:81:10)

Which gives me some wierd IP address 1.0.0.1:443.
I also have :"http.proxyStrictSSL": false in vscode user settings

[joaomoreno]

This is really strange.

Can you run this simple NodeJS script by putting in script.js and running node script.js from the Command Prompt?

http.get('http://www.google.com/index.html', (res) => {
  console.log(`Got response: ${res.statusCode}`);
  // consume response body
  res.resume();
}).on('error', (e) => {
  console.log(`Got error: ${e.message}`);
});

What do you get from it?

[ovidiubuligan]

node doesn't seam to use proxy settings from environment variables. I get:

c:\PRJ\Temp>node script.js
Got error: getaddrinfo EAI_AGAIN www.google.com:80

[joaomoreno]

EAI_AGAIN is also not an error related to proxying... Try that snippet again later.

[ovidiubuligan]

nslookup command doesn't work at all also

C:\Users\myuser>nslookup google.com
Server:  internalhost.company.com
Address:  10.169.96.251

*** internalhost.company.com can't find google.com: Server failed

Other programs after I set them to use a proxy they work also solving dns queries through proxies.
Can this be a issue with vscode ?

[joaomoreno]

Not sure, since Code appears to try to reach your proxy 10.0.1.1:3128 but fails in doing so. Something is definitely up.

Can you try the Atom editor, which also has a proxy setting?

[ovidiubuligan]

Hello, sorry for the late reply,
After Atom testing I got the same behavior I think:

Fetching featured packages failed.Hide output…
tunneling socket could not be established, cause=getaddrinfo ENOTFOUND

I also urlencoded the password and @ symbol for passwords.
There is no error in the Dev tools console (unlike Vscode).
I am not really sure if I placed the settings in the right config file location.
Setting http-proxy strict-ssl in the http the ~\.atom\.apm\.apmrc seams to resset to default almost empty file after I restart atom.
I copyied .apmrc up one level since I have read somewhere that there it should be , so I have ~\.atom\.apmrc. and the settings seam to stay there and the error (first image) is shown.

Deleting the proxy configuration from ~\.atom\.apmrc gives me a different error shown bellow:

Fetching featured packages failed.Hide output…
tunneling socket could not be established, cause=connect EAFNOSUPPORT

So a different error message meaning that proxy setting is somehow taken into account.
Do you have any suggestions on what to try next

[joaomoreno]

I am really not sure. It doesn't look proxy related but rather a problem with your system's configuration.

Seems like the guys at nodejs/node would be able to help you out. Just describe what you described here.

[ovidiubuligan]

Hello, sorry for commenting on a closed issue. I just want to try an extra scenario.
It is most probably related to : nodejs/node#1490 , To also tunnel DNS requests through proxy.

Can I store dc.services.visualstudio.com and vortex.data.microsoft.com ip addresses
in the config next to the proxy settings somehow ,similar co etc/hosts , but without modifying windows etc/hosts ?

[joaomoreno]

What do you mean by store? What do you intend to accomplish?

[ovidiubuligan]

I updated the comment. I meant something like :

dns : {
  "dc.services.visualstudio.com" : "40.114.241.141",
  "vortex.data.microsoft.com": "191.232.139.254"
}

And use somehow those ip's ... but this is again an aspect of node js. But maybe there is some way .

Edit:
I just tried adding the mappings to windows etc/hosts file and I get:

Error: connect EAFNOSUPPORT 191.232.139.254:443 - Local (undefined:undefined) at Object.exports._errnoException (util.js:837:11) at exports._exceptionWithHostPort (util.js:860:20) at connect (net.js:838:14) at net.js:981:7 at GetAddrInfoReqWrap.asyncCallback [as callback] (dns.js:62:16) at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:81:10)
address: "191.232.139.254"
code: "EAFNOSUPPORT"
errno: "EAFNOSUPPORT"
message: "connect EAFNOSUPPORT 191.232.139.254:443 - Local (undefined:undefined)"

[joaomoreno]

So what do you get when running this in the command line?

node -e "require('dns').resolve4('dc.services.visualstudio.com', (err, result) => console.log(err, result))"

[ovidiubuligan]

I get :

{ [Error: queryA ESERVFAIL dc.services.visualstudio.com]
  code: 'ESERVFAIL',
  errno: 'ESERVFAIL',
  syscall: 'queryA',
  hostname: 'dc.services.visualstudio.com' } undefined

I get this regardless of etc/hosts ip mappings . (I tried with mappings and without mappings)

[joaomoreno]

How about:

node -p "require('dns').getServers()"

[joaomoreno]

And also:

node -e "require('dns').lookup('dc.services.visualstudio.com', (err, result) => console.log(err, result))"

[ovidiubuligan]

I get this (I think it is safe to show them) :

[ '10.8.68.251',
  '10.8.132.253',
  'fec0:0:0:ffff::1',
  '10.169.96.251',
  '10.8.132.253',
  '10.169.96.251',
  '10.8.132.253',
  'fec0:0:0:ffff::1',
  '10.169.96.251',
  '10.8.132.253' ]

[joaomoreno]

How about the last snippet?

[ovidiubuligan]

Last snippet : node -e "require('dns').lookup('dc.services.visualstudio.com', (err, result) => console.log(err, result))"
returns :

{ [Error: getaddrinfo EAI_AGAIN]
  code: 'EAI_AGAIN',
  errno: 'EAI_AGAIN',
  syscall: 'getaddrinfo',
  hostname: 'dc.services.visualstudio.com' } undefined

(I have no ip mappings in etc/hosts)

[ovidiubuligan]

It works now. It was a problem with an "WideCap" proxyfier app i had installed . Which made this and some other software (office) not work .
