when i run my nagios server as dhcp client i get ip lease to it. dhcp work fine however when i try to run check_dhcp it fails.
here is how i am runing check_dhcp
./check_dhcp -s 160.78.76.54 -t 40 -i eth0 -v
DHCP socket: 3
Hardware address: 000e0cb529c0
DHCPDISCOVER to 255.255.255.255 port 67
DHCPDISCOVER XID: 465293895 (0x1BBBD247)
DHCDISCOVER ciaddr: 0.0.0.0
DHCDISCOVER yiaddr: 0.0.0.0
DHCDISCOVER siaddr: 0.0.0.0
DHCDISCOVER giaddr: 0.0.0.0
send_dhcp_packet result: 548
No (more) data received
Result=ERROR
Total responses seen on the wire: 0
Valid responses for this machine: 0
DHCP problem: No DHCPOFFERs were received.
please note when i run check_dhcp my nagios server is using a static ip address and eth0 is the only interface present on my nagios server.
my dhcp server is an infoblox network device (Black Box)

Please make sure you reply to the mailing list rather than me
personally. This way other people can follow the thread and help you as
well, or see a solution if they have this problem and are reading an
archive of it.
What is your primary interface on the box on which you are running this
plugin? If it is eth1 for example, the plugin uses eth0 by default and
you will get no response on the interface because it is not the active
one. In that case you would need to run
./check_dhcp -i eth1
to make it use the right interface.
Also, have you tried doing
./check_dhcp -vvv [other options you need]
could you please reply with the full output of that?
We really need more information otherwise all we can do it guess what
the problem is.

Post by trevor obbaHas anyone successfully had any check_dhcp nagios plugin working on infoblox? I could not get it to working on Infoblox
network appliance, I not even getting any log in infoblox logs
It should work from your linux server over the standard ethernet for any
dhcp server that responds over the network. If your black box solution
"Infoblox" which I am not familiar with, actually responds to dhcp
requests with dhcp offers then it should work the same as any other dhcp
server test.
Post by trevor obbaI am running Nagios 2.5 on Suse enterprise linux 10, I am running check_dhcp
version 0.1
Do you have ideas why check_dhcp.pl is not working for infoblox network
alliances? What am I doing rough? Can you help please?
Version 0..1? That sounds completely wrong. I am using the standard plugin from the nagios plugins distribution which is not a perl plugin but a compiled plugin, and that is version 1.8 from nagios-plugins 1.4.8.
Check you are using the right plugin and then try again?
