   Nice script.
   I found it best to add a trim() around the [updated] element.

   Useful. Thanks.
   Suggestion: if the logfile passed to parseLog() fails to fopen() correctly, the script loops endlessly. After the fopen(), do a test to make sure it actually opened, perhaps like this:
   function parseLog ($log, $proto) {
   $handle = fopen($log, “r”);
   if(!$handle)return false;

   If you want to use this script with ethernet bridge (aka TAP) mode you need to change the second expression to:
   preg_match(“/^(.+[:\.].+),(.+),(\d+\.\d+\.\d+\.\d+\:\d+),(.+)$/”, $buffer, $match)

   I modified this script so that it is possible to get the status info directly from the management console of an openvpn daemon!
   function parseLogConnection ($pass,$server=”127.0.0.1″,$port=5555, $proto) {
   global $debug_out;
   $handle = fsockopen($server, $port, $errno, $errstr, 3);
   if(!$handle)
   return false;
   $uid = 0;
   $output = fgets($handle, 15); //”ENTER PASSWORD:” !!no newline at the end
   if (strstr($output,”PASSWORD”))
   {
   fputs($handle, “$pass\n”);
   //fflush($connection);
   $output = fgets($handle, 100);
   if (strstr($output,”SUCCESS”)){
   $output = fgets($handle, 100); // INFO: line
   fputs($handle, “status\n”);
   $buffer=””;
   while (!feof($handle) && !strstr($buffer,”END”)) {
   $buffer = fgets($handle, 4096);
   unset($match);
   if (ereg(“^Updated,(.+)”, $buffer, $match)) {
   $status[‘updated’] = $match[1];
   }
   $i=0;
   if (preg_match(“/^(.+),(\d+\.\d+\.\d+\.\d+\:\d+),(\d+),(\d+),(.+)$/”, $buffer, $match)) {
   $i++;
   if ($match[1] > “Common Name”) {
   //$debug_out[‘match1’][$i]=$match;
   $cn = $match[1];
   // associative array to store a numeric id
   // for each remote ip:port because smarty doesnt
   // like looping on strings in a section
   $userlookup[$match[2]] = $uid;
   $status[‘users’][$uid][‘CommonName’] = $match[1];
   $status[‘users’][$uid][‘RealAddress’] = $match[2];
   $status[‘users’][$uid][‘BytesReceived’] = sizeformat($match[3]);
   $status[‘users’][$uid][‘BytesSent’] = sizeformat($match[4]);
   $status[‘users’][$uid][‘Since’] = $match[5];
   $status[‘users’][$uid][‘Proto’] = $proto;
   $uid++;
   }
   }
   $i=0;
   if (preg_match(“/^(.+[:\.].+),(.+),(\d+\.\d+\.\d+\.\d+\:\d+),(.+)$/”, $buffer, $match)) {
   $i++;
   if ($match[1] > “Virtual Address”) {
   //$debug_out[‘match2’][$i]=$match;
   $address = $match[3];
   // find the uid in the lookup table
   $uid = $userlookup[$address];
   $status[‘users’][$uid][‘VirtualAddress’] = $match[1];
   $status[‘users’][$uid][‘LastRef’] = $match[4];
   }
   }
   }
   /* if (is_array($debug_out)){
   $debug_out[‘userlookup’]=$userlookup;
   $debug_out[‘status’]=$status;
   $debug_out[‘file’]=file($log);
   }
   */
   fputs($handle, “exit\n”);
   fclose($handle);
   return($status);
   }
   }
   return false;
   }

   Do you have a source php file that generates the output of your sample?
   I can’t get it to work due to my lack of Smarty knowledge…

   after ALOT of tries i came to this…hope is helps somebody!

   thats inside the html-body:
   assign(‘tcpusers’, $tcpusers[users]);
   $smarty->display(‘smarty_vpn.tpl’);

   echo “Letzte Aktualisierung: $tcpusers[updated]“;

   ?>

   the template had to be in a extra ‘templates’ directory…
   also there had to be an ‘templates_c’ directory, writeable by the www-user.
