title: Logstash will not bind the UDP hostname of the syslog server
body: <p>I have a centralized Syslog-ng server that outputs logs to port 10150 and when I do a UDP dump on that port I am able to see the logs being written to that port and IP.
  On another server that contains the Logstash daemon on version 1.3+.  I am trying to read from UDP using input against that Syslog-ng server and I am getting this error:</p>
  
  <pre><code>&lt;SocketError: bind: name or service not known&gt;
  </code></pre>
  
  <p>For my Logstash daemon server I am using the following input:</p>
  
  <pre><code>input {
    udp {
      host =&gt; "syslog-ng.somedomain.com"
      port =&gt; 10510
      type =&gt; "syslog"
    }
  }
  </code></pre>
  
  <p>I have my firewall between both of them wide open on that particular port.
  Does anyone have any idea why Logstash 1.3+ is unable to read from that UDP port against that server?
  Thanks in advance,
  Cole</p>
