<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transational//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=UTF-8"> </HEAD> <BODY>Hello, I try to check my DHCP server with Nagios 3.0.3 thanks to the check_dhcp plugins coming from the 1.4.13 plugin pack. My approach is, my Nagios server is located in a network 192.168.90.X and my DHCP server 192.168.105.X. And I try to check the correct work of DHCP server with the following command : <div style="text-align: left; margin-left: 40px; font-family: arial,helvetica,sans-serif; color: rgb(0, 0, 204);">./check_dhcp -v -u -s 192.168.105.Y -r 192.168.90.B -m 01:AB:23:CD:45:EF Requested server address: 92.168.105.Y Hardware address: 1:AB:23:CD:45:EF DHCP socket: 3 Pretending to be relay client 192.168.90.B DHCPDISCOVER to 192.168.X.Y port 67 DHCPDISCOVER XID: 164920453 (0x9D47C85) DHCDISCOVER ciaddr: 0.0.0.0 DHCDISCOVER yiaddr: 0.0.0.0 DHCDISCOVER siaddr: 0.0.0.0 DHCDISCOVER giaddr: 192.168.90.B send_dhcp_packet result: 548 recv_result_1: 331 recv_result_2: 331 receive_dhcp_packet() result: 331 receive_dhcp_packet() source: 192.168.105.Y Result=OK DHCPOFFER from IP address 192.168.X.Y via 192.168.105.Y DHCPOFFER XID: 164920453 (0x9D47C85) DHCPOFFER chaddr: 01AB23CD45EF DHCPOFFER ciaddr: 0.0.0.0 DHCPOFFER yiaddr: 192.168.90.B DHCPOFFER siaddr: 0.0.0.0 DHCPOFFER giaddr: 192.168.90.B Option: 53 (0x01) Option: 54 (0x04) Option: 51 (0x04) Option: 1 (0x04) Option: 6 (0x08) Option: 12 (0x12) Option: 58 (0x04) Option: 59 (0x04) Lease Time: 604800 seconds Renewal Time: 302400 seconds Rebinding Time: 529200 seconds Added offer from server @ 192.168.105.Y of IP address 192.168.90.B No (more) data received (nfound: 0) Result=ERROR Total responses seen on the wire: 1 Valid responses for this machine: 1 DHCP Server Match: Offerer=192.168.105.Y Requested=192.168.105.Y OK: Received 1 DHCPOFFER(s), 1 of 1 requested servers responded, requested address (192.168.90.B was offered, max lease time = 604800 sec. </div> I've make a reservation in my infoblox with this MAC address. I try to analyse the return code but I have nothing, <div style="text-align: left; margin-left: 40px; font-family: arial,helvetica,sans-serif;">echo $result ==> NOTHING </div> How I can verify, if the check works well, and In my web nagios interface toward the check_dhcp I have : (null). <img> My declarations in the differents config files : <div style="margin-left: 40px; color: rgb(0, 51, 255);">Commands.cfg : ------------------------ #'check_dhcp' command definition avec réservation adresse MAC define command{ command_name check_dhcp command_line sudo $USER1$/check_dhcp -u -s 192.168.105.X -r 192.168.90.Y -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 192.168.105.X } </div> <div style="margin-left: 40px; color: rgb(0, 51, 255);">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 } </div> <div style="text-align: left; font-family: arial,helvetica,sans-serif;" id="result_box" dir="ltr">How to solve problem with the server Infoblox?
