title: Ganglia fails communicate between meta and monitored nodes
body: <p>We've been advised to try Ganglia as a monitoring tool for our cluster.</p>
  
  <p>The installation was pretty smooth but I have a problem with connectivity between gmond and gmetad.
  Meta node is able to see(on web) only local gmond host (itself).</p>
  
  <p>The configuration of gmetad (10.45.11.26 is gmetad localhost):</p>
  
  <pre><code>data_source "hbase" 10.45.11.26
  </code></pre>
  
  <p>The configuration of gmond(10.45.11.27 is gmond localhost):</p>
  
  <pre><code>cluster {
  name = "hbase"
  owner = "unspecified"
  latlong = "unspecified"
  url = "unspecified"
  }
  
  udp_send_channel {
  host=10.45.11.26
  port = 8649
  ttl = 1
  }
  
  udp_recv_channel {
  port = 8649
  bind = 10.45.11.27
  }
  
  tcp_accept_channel {
  port = 8649
  }
  </code></pre>
  
  <p>Telnet from gmetad to gmond on port 8649 returns xml.
  I can see udp traffic coming from gmond on gmetad node (tcpdump)</p>
  
  <p>What I'm missing here?</p>
