title: Concurrent Connection Test
body: <p>So I ran into a network problem the other day and I was trying to find a way to test for this problem in the future.</p>
  
  <p>I had a lot of users online at once and hit my routers max IP connection limit (not DHCP! TCP/UDP connections.)</p>
  
  <p>Once I figured out what the problem was it was fairly simple to fix however I was wondering if there is any way to simulate this kind of activity? Everything worked fine when I tested it, it wasn't until I had 150+ users that I discoved I had a problem.</p>
  
  <p>I have spent the last 3-4hrs looking for such a test/audit tool. Here is what I found:</p>
  
  <ol>
  <li><a href="http://bittwist.sourceforge.net/" rel="nofollow">http://bittwist.sourceforge.net/</a> -DDoS simulator (can't make it work, barly get +300 connections)</li>
  <li><a href="http://stevesouders.com/hpws/max-connections.php" rel="nofollow">http://stevesouders.com/hpws/max-connections.php</a> -Browser concurrent connection tester (This hits the browser limit (6 in chrome) w/o making a dent on my router even open in 70+ tabs at the same time)</li>
  <li><a href="http://www.smallnetbuilder.com/lanwan/lanwan-howto/31103-how-we-test-hardware-routers-revision-3" rel="nofollow">http://www.smallnetbuilder.com/lanwan/lanwan-howto/31103-how-we-test-hardware-routers-revision-3</a> -Some tool linked about halfway down the page (Reads like its exactly what I want, however it barely has a noticable effect on my router.)</li>
  <li><a href="http://www.http-kit.org/600k-concurrent-connection-http-kit.html" rel="nofollow">http://www.http-kit.org/600k-concurrent-connection-http-kit.html</a> -Concurrent HTTP connection simulator (This one seems like it would do what I want, but my linux-foo is limited and I can't get it working. <em>tear</em>)</li>
  </ol>
  
  <p>So do you guys have a tool to test your routers with? I would love something that does both TCP/UDP.</p>
  
  <p>(btw, for anyone misunderstanding I'm not trying to test "speed", just sheer number of connections)</p>
  
  <p>Thanks!
