#Taking advantage of open relays

##Introduction

An open relay is a mail server that allows anyone to send email through it. Unfortunately this used to be the default and in some cases still is, but it has become a tool in most spammers arsenals, to send unsolicited email to anyone and sometimes from anyone. This is no longer the default configuration in many cases, however sometimes you'll find that sys admins either from lazyness or just not thinking of security when configuring a server, create open relays all the time.

##Testing procedure

To test for an open relay, one can either use one of the many excellent tools, such as (http://www.aupads.org/test-relay.html), it's quite simple to check for. But how does one actually do this manually? If you know how, you'll understand better the problem and how applications we use everyday work.

Turn Ubuntu based distros into a better WiFi hotspot

---

Use the following instructions to set up, configure, and run a WiFi hotspot from your computer. Note: The strength will increase with more connections.

1. Add the following ppa: sudo add-apt-repository ppa:nilarimogard/webupd8
2. Run: sudo apt-get update && sudo apt-get install ap-hotspot

After install, ap-hotspot must be configured, however first if using any sort of firewall, unblock the following apps:

var crypto = require('crypto');
function encrypt(text){
  var cipher = crypto.createCipher('aes-256-cbc','d6F3Efeq');
  var crypted = cipher.update(text,'utf8','hex');
  crypted += cipher.final('hex');
  return crypted;
}
function decrypt(text){
  var decipher = crypto.createDecipher('aes-256-cbc','d6F3Efeq');
  var dec = decipher.update(text,'hex','utf8');
