Multiple Instances of net Sockets

[Muhammad Shahzad]

I have used net sockets library, and have made a class, i initialize two objects with different IP's and same PORT number, when i get connect with both objects, both show the IP of last connected object, even i have used this.Socket = new require( 'net' ).Socket(); in the constructor :(

Reason might be the that connect function shows recent IP being passed. see the code below.

Response that i get:

CONNECTED TO: 10.0.20.105:8898

CONNECTED TO: 10.0.20.105:8898

Connecting to SQL...

SQL Connection Successful...

Scales = require( './scales.class.js' );
var one = new Scales( "10.0.20.104", 8899 );
one.Init().Process();
var one = new Scales( "10.0.20.105", 8898 );
one.Init().Process();

Yes. According to the code you sent..

I think you are overwriting the variable.

its:

Scales = require( './scales.class.js' );
var one = new Scales( "10.0.20.104", 8899 );
one.Init().Process();
var one = new Scales( "10.0.20.105", 8898 );
one.Init().Process();

it should be:

Scales = require( './scales.class.js' );
var one = new Scales( "10.0.20.104", 8899 );
one.Init().Process();

var two = new Scales( "10.0.20.105", 8898 );
two.Init().Process();
