Hi, I have installed DevStack on a m3.large instance of AWS-EC2 and the installation went smoothly and I did not get any errors. Now I am using the node-js based pkgcloud sdk to fetch data from it but it is erroring out, Could someone please point out what I am doing wrong or where do I need to look or change something to get this working.

I am pasting the code and the error below

var pkgcloud = require('pkgcloud');
var openstack = pkgcloud.compute.createClient({
    provider: 'openstack',
    username: 'myusername',
    password: 'mypassword',
    region: 'nova',
    tenantId: 'admin',
    authUrl: 'http://ip-address/identity'
//console.log("openstack "+JSON.stringify(openstack,null,'\t'))
openstack.getServers(function(err, containers) {
    if (err)
        console.log("Err " + err + JSON.stringify(err, null, '\t'));
        console.log("Servers " + JSON.stringify(containers, null, '\t'));

The Error that I get is this:

Error: Error (401): Unauthorized{
        "message": "Error (401): Unauthorized",
        "stack": "Error: Error (401): Unauthorized\n    at Object.exports.handle (D:\\Siddharth\\30.Sublime-workspace\\openstack-poc\\node_modules\\errs\\lib\\errs.js:203:19)\n    at D:\\Siddharth\\30.Sublime-workspace\\openstack-poc\\node_modules\\pkgcloud\\lib\\pkgcloud\\openstack\\client.js:214:23\n    at D:\\Siddharth\\30.Sublime-workspace\\openstack-poc\\node_modules\\pkgcloud\\lib\\pkgcloud\\openstack\\client.js:162:14\n    at Request._callback (D:\\Siddharth\\30.Sublime-workspace\\openstack-poc\\node_modules\\pkgcloud\\lib\\pkgcloud\\openstack\\context\\identity.js:160:14)\n    at Request.self.callback (D:\\Siddharth\\30.Sublime-workspace\\openstack-poc\\node_modules\\request\\request.js:123:22)\n    at emitTwo (events.js:100:13)\n    at Request.emit (events.js:185:7)\n    at Request.<anonymous> (D:\\Siddharth\\30.Sublime-workspace\\openstack-poc\\node_modules\\request\\request.js:1047:14)\n    at emitOne (events.js:95:20)",

                        "code": 401,
                        "title": "Unauthorized"

The same credentials work when I login using the web based interface, but here I get 401, I am kinda stuck any help would really be appreciated.

Thanks Siddharth

The above was resolved, my authURL was not correct(oo man what a badiee) Anyway pkgcloud cannot be used for openstack deployed inside of AWS-EC2, reason as follows: 1. The createclient makes a call to fetch the authId and the service catalog. 2. The service catalog has the ip address endpoints pointing to an internally mapped IP allocated by AWS. 3. This ip is totally internal and private and not available. 4. So when pkgcloud extracts compute API endpoint and tries to call it , it times out,

 Error: connect ETIMEDOUT{
        "message": "connect ETIMEDOUT",
        "stack": "Error: connect ETIMEDOUT\n    at Object.exports._errnoException (util.js:856:11)\n    at exports._exceptionWithHostPort (util.js:879:20)\n    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1057:14)",
        "code": "ETIMEDOUT",
        "errno": "ETIMEDOUT",
        "syscall": "connect",
        "address": "",
        "port": 8774

Hence answering my own question :)
