title: How to run multiple Tor processes at once with different exit IPs?
body: <p>I am brand new to Tor and I feel like multiple Tors should be considered. The multiple tors I mentioned here are not only multiple instances, but also using different proxy ports for each, like what has been done here 
  <a href="http://www.howtoforge.com/ultimate-security-proxy-with-tor">http://www.howtoforge.com/ultimate-security-proxy-with-tor</a>)</p>
  
  <p>I am trying to get started with 4 Tors. However, the tutorial applies only to Arch Linux and I am using a headless EC2 ubuntu 64bits. It is really a pain going through the differences between Arch and Ubuntu. And here I am wondering is there anyone could offer some help to implement my idea simplicitly.</p>
  
  <ol>
  <li><p>Four Tors running at the same time each with an individual port, privoxy or polipo or whatever are ok once it works.
  Like:
  8118 &lt;- Privoxy &lt;- TOR &lt;- 9050
  8129 &lt;- Privoxy &lt;- TOR &lt;- 9150
  8230 &lt;- Privoxy &lt;- TOR &lt;- 9250
  8321 &lt;- Privoxy &lt;- TOR &lt;- 9350</p></li>
  <li><p>In this way, if I try to return the ip of 127.0.0.1:8118, 8129, 8230 and 8321, they should return four different ips, which indicates there are four different Tors running at the same time. Then, a few minutes later, check again, all four of them should have a new ips again.</p></li>
  </ol>
  
  <p>I know my simple 'dream' could come true in many ways, however... I am not only new to Tor, but even also to bash and python... That is why I come here and see whether some of you could light me up. </p>

  Best,</p>
  
  <p>btw, if I run 
      <code>$ ps -A | grep 'tor'</code>
  i have several instances there, however with "?" under the tty column, what does that mean since I know tty means terminals?</p>
