The following code produces an exception in node.js under windows:
var Socket = require("net").Socket;
socket = new Socket();
socket.connect(80, "localhost");
here’s the message:
events.js:2083: Uncaught Error: getHostByName ENOTFOUND
When I remove localhost, it works fine. What could be causing this?
I tried turning the firewall off, but to no effect.
node.js uses c-ares resolver and ignores system resolver completely. So the advices regarding C:\WINDOWS\system32\drivers\etc\hosts are probably irrelevant.
c-ares library reads certain system config files – e.g. on Windows and Cygwin it reads /etc/resolv.conf. So you should check if it reads /etc/hosts or C:\WINDOWS\system32\drivers\etc\hosts. If it doesn’t and doesn’t have builtin support for localhost – then you will have to use 127.0.0.1
