Summary: Problem check_dhcp on infoblox

Initial Comment:
Hello,

I try to check my DHCP server with Nagios 3.0.3 thanks to the "check_dhcp" plugins coming from the 1.4.13plugin pack on RedHat Entreprise R5 Server (2.6.18),  (i386 or i686 because I have i686 i686 i386 when i launch uname -a). I use gcc 4.1.2-44.

My approach is, my Nagios server is located in a network 192.168.A.B and my DHCP server 192.168.X.Y. And I try to check the correct work of DHCP server with the following command :
./check_dhcp -v -u -s 192.168.X.Y -r 192.168.A.B -m 01:AB:23:CD:45:EF
Requested server address: 92.168.X.Y

I've make a reservation in my infoblox with this MAC address. I try to analyse the return code but I have nothing,
echo $result ==> NOTHING

How I can verify, if the check works well, and In my web nagios interface toward the check_dhcp I have : (null).


My declarations in the differents config files :
Commands.cfg :
------------------------
#'check_dhcp' command definition avec réservation adresse MAC
define command{
    command_name     check_dhcp
    command_line        sudo $USER1$/check_dhcp -u -s 192.168.X.Y -r 192.168.A.B -m 01:AB:23:CD:45:EF
    }

#'check_dhcp2' command definition avec réservation adresse MAC au travers de variable
define command{
    command_name     check_dhcp2
    command_line         sudo $USER1$/check_dhcp -v -u -s $ARG1$ -r $ARG2$ -m $ARG3$
    }

#'check_dhcp3' command definition simple
define command{
    command_name     check_dhcp3
    command_line        sudo $USER1$/check_dhcp -u -s 192.168.X.Y
    }

Switch.cfg :
-----------------
#Define a service to check the DHCP service   

define service{
    use                               generic-service
    host_name                 infoblox-forum
    service_description  dhcp reservation MAC
    check_command      check_dhcp
    }   

define service{
    use                              generic-service
    host_name                   infoblox
    service_description     dhcp2 reservation MAC avec ARG
    check_command        check_dhcp2
    }   

define service{
    use                           generic-service
    host_name                infoblox
    service_description    dhcp3 sans rien
    check_command       check_dhcp3
    }

How to solve problem with the server Infoblox? And how to test the return code of the plugins?

Thank you in advance, for your help.
