title: Disable and re-enable address space layout randomization only for myself
body: <p>I would like to disable address space layout randomization (ASLR) on my system (Ubuntu Gnu/Linux 2.6.32-41-server), but, if I use</p>
  
  <pre><code>sysctl -w kernel.randomize_va_space=0
  </code></pre>
  
  <p>the change would affect all users on the system, I presume.  (Is this true?)  How can I limit the effects of disabling ASLR to myself as a user only, or only to the shell session in which I invoke the command to disable?</p>
  
  <p>BTW, I see that my system's current (default) setting is</p>
  
  <pre><code>kernel.randomize_va_space = 2
  </code></pre>
  
  <p>Why 2 and not 1 or 3?  Where can I find documentation about the numerical values of /proc/sys settings, their ranges, and their meanings?  Thanks!</p>
