[op5-users] Statistics/ICMP downed host detection without root privilgies

[Mikael.Schmidt at ixx.se]

Hi,

I had an issue with 2 hosts that I couldn't get graphed simply because the only way to detect if they were alive was via ICMP. Naturally, I don't wish to run it as root which is a must for the current ping.php to work. Replacing the ping_icmp function within /opt/statistics/lib/ping.php with the one below removes the need of running as root. Could we perhaps add this to future versions of Statistics?

   function ping_icmp() {
      /* ping me */
      if ($this->host["hostname"]) {
         /* initialize variables */
         $this->ping_status = "down";
         $this->ping_response = "ICMP Ping timed out";

         /* establish timeout variables */
         $to_sec = floor($this->timeout/1000);
         $to_usec = ($this->timeout%1000)*1000;

         /* clean up hostname if specifying snmp_transport */
         $this->host["hostname"] = str_replace("TCP:", "", $this->host["hostname"]);
         $this->host["hostname"] = str_replace("UDP:", "", $this->host["hostname"]);

         /* determine the host's ip address */
         $host_ip = gethostbyname($this->host["hostname"]);
         $this->ping_response = "$host_ip";
                  $ping_output = system("ping $host_ip -c 1", $retval);

                  preg_match('/rtt/', $ping_output, $ping_worked);
                  if ($ping_worked){
            $this->ping_status = 1000;
            $this->ping_response = "Host is alive";
                        return true;
                  }else {
                      $this->response = "Host is dead";
                      return false;
                  }
           }
   }
