A parser for the openvpn 2 status log file.
 
 Typical openvpn 2 status log file looks more or less like this:


	OpenVPN CLIENT LIST
	Updated,Thu Mar  3 17:24:54 2005
	Common Name,Real Address,Bytes Received,Bytes Sent,Connected Since
	common.name,1.2.3.4:21370,86559,87369,Thu Mar  3 13:39:10 2005
	other.common.name,7.8.9.1:54836,159509,167386,Thu Mar  3 13:39:10 2005
	ROUTING TABLE
	Virtual Address,Common Name,Real Address,Last Ref
	192.168.57.14,other.common.name,7.8.9.1:54836,Thu Mar  3 17:23:10 2005
	192.168.57.10,common.name,1.2.3.4:21370,Thu Mar  3 13:39:11 2005
	GLOBAL STATS
	Max bcast/mcast queue length,0
	END

 The parseLog function expects a path to a log file and a protocol.  The
 protocol string is simply there to support an environment where you run
 multiple openvpn daemons to listen on different ports or protocols, it is
 a plain text field, suggested values are 'UDP', 'TCP', 'UDP/1234' etc.
 
 Returned entries are indexed based on client host:port since that is 
 guaranteed to be unique, common name wouldn't be unique since you can 
 connect multiple times with the same cert.

 The parser will return a multi dimentional array given the status log above
 that looks like this:

 Array
 (
    [updated] => Thu Mar  3 17:30:55 2005
    [users] => Array
      (
            [0] => Array
              (
                 [CommonName] => common.name
                 [RealAddress] => 1.2.3.4:21370
                 [BytesReceived] => 86.39 KB
                 [BytesSent] => 87.18 KB
                 [Since] => Thu Mar  3 13:39:10 2005
                 [Proto] => UDP
                 [VirtualAddress] => 192.168.57.10
                 [LastRef] => Thu Mar  3 13:39:11 2005
              )
            [1] => Array
              (
                 [CommonName] => another.common.name
                 [RealAddress] => 7.8.9.1:54836
                 [BytesReceived] => 158.04 KB
                 [BytesSent] => 166.02 KB
                 [Since] => Thu Mar  3 13:39:10 2005
                 [Proto] => UDP
                 [VirtualAddress] => 192.168.57.14
                 [LastRef] => Thu Mar  3 17:27:14 2005
              )
      )
 )

 I use a Smarty template to print out the data like this:

 <table>
 {section name=u loop=$tcpusers}
   <tr bgcolor="{cycle values="#eeeeee,#dddddd"}">
      <td>{$tcpusers[u].CommonName}</td>
      <td>{$tcpusers[u].RealAddress}</td>
      <td>{$tcpusers[u].VirtualAddress}</td>
      <td>{$tcpusers[u].Since}</td>
      <td>{$tcpusers[u].BytesSent}</td>
      <td>{$tcpusers[u].BytesReceived}</td>
      <td>{$tcpusers[u].LastRef}</td>
      <td>{$tcpusers[u].Proto}</td>
   </tr>
 {/section}
 </table>
