My operating system is Windows 10 Version 10586 and node.js is Version 4.4.5.
When I use the module raw-socket follow the example in this page
https://github.com/stephenwvickers/node-raw-socket
When running code like this:
var raw = require ("raw-socket");
var socket = raw.createSocket ({protocol: raw.Protocol.None});
I got following error:
C:\Users\KEEY\node_modules\raw-socket\index.js:47
this.wrap = new raw.SocketWrap (

How to solve it?
Thanks for everyone's help.
I email Stephen Vickers,the author of the module raw-socket,the source of problem is that
Stephen Vickers:
It looks like you don't have permissions to open raw sockets on that platform.
Then I run it as administrator, it works!
Thank you,Stephen Vickers
try this
var socket = raw.createSocket ({
protocol: raw.Protocol.None,
socketOption: raw.SocketOption.IPV6_HDRINCL
});

I found a workaround for this which was suggested by someone else in github. In wit.js line 300 replace
this.rl.write(null, {ctrl: true, name: 'e'});
with
this.rl.write( '', {ctrl: true, name: 'e'});
I am getting this error when i try to use node-gcm in my code. I have included it as per standard methods require('node-gcm')
var message = new gcm.Message();

Can someone help me out?
Judging by this issue, it may be that an alpha version of node-gcm was mistakenly published as being the latest stable one.
Until that's fixed, you can try this to get your code working again:
npm install node-gcm#0
EDIT: the issue should be fixed now.
Hi All I am very new to the nodejs.
I am trying to install the cryptlib module by using the following command for this:
npm install cryptlib
It installing successfully. When I move to myproject ->node_modules the folder called cryptlib is there.
But when I include it in my server.js as follow
var CryptLib = require('cryptlib'),
_crypt = new CryptLib(),
plainText = 'This is the text to be encrypted',
iv = _crypt.generateRandomIV(16), //16 bytes = 128 bit
key = _crypt.getHashSha256('my secret key', 32), //32 bytes = 256 bits
cypherText = _crypt.encrypt(plainText, key, iv),
originalText = _crypt.decrypt(cypherText, key, iv);
Then its throwing an error
module.js:340
throw err;
^
Error: Cannot find module 'cryptlib'

So how can I fix this error? Any help would be appriciated.
Sorry I dont have enough points to reply as a comment before this.
I have updated cryptlib on npm to version 1.0.3 to address this issue. It should work now. Thank you 王庭茂 for your excellent effort.
Also thank you user3446467 for using the module.
If you encounter any further issues please let me know.
It seems to be the problem of the original package. I have sent a pull request to fix this problem. For now, just do what I have done on the pull request and it should work.
i'm following the lynda.com tutorials, love this site, i got my hello world with console.log()
my next task is to try this script
var os = required('os');
var message = 'This script is running on Node.js ' + process.version + ' on a '
+ os.type() + '-based operating system.';
console.log(message);
my error in the terminal

I double checked my spelling and check my semicolons (that doesn't really matter in node.js like javascript right) but yea any help? i just started. I don't understand why required is not defined, i installed node. was i suppose to install 'os'?
It's require, withoud d:
var os = require('os');
Hello I'm trying to make some Javascript files working on nodeJS everything is well set however here is the error I get :

The files I'm using are :
myServer.js
var my_module = require("./myFunctionsCallTest.js");
console.log("RSA encrypted message :"+ my_module.Encrypt("myKey","myMessage"));
myFunctionsCallTest.js //This file contains some call of prototypes like :
.....................................
RSAKey.prototype.setPublic = RSASetPublic;
RSAKey.prototype._short_encrypt = RSAEncrypt;
RSAKey.prototype.encrypt = RSAEncryptLong;
RSAKey.prototype.encrypt_b64 = RSAEncryptB64;

Any idea from where this issue could come?
Thanks.
It looks like you're using Tom Wu's BitInteger and RSA JavaScript library. This library was designed for use in the browser and doesn't work quite right in Node.js.
Luckily, someone has already gone through the work of packaging this library in a Node.js compatible format; it's on GitHub at https://github.com/eschnou/node-bignumber and available via npm as the package "bignumber", and comes with a nice example.
