[Nagiosplug-help] check_dhcp across subnets

[Scott Machtmes]

I am using the latest check_dhcp plugin (check_dhcp v1810 nagios-plugins 
1.4.11). It works fine on the local subnet. I can't get it to work 
across subnets to remote dhcp servers. Am I missing or not understanding 
something?

I've tried:

# ./check_dhcp -vvv -u -s 10.32.240.135

Requested server address: 10.32.240.135
DHCP socket: 3
Hardware address: 00:02:55:ac:2e:33
Pretending to be relay client 10.32.2.37
DHCPDISCOVER to 10.32.240.135 port 67
DHCPDISCOVER XID: 406794260 (0x183F3014)
DHCDISCOVER ciaddr:  0.0.0.0
DHCDISCOVER yiaddr:  0.0.0.0
DHCDISCOVER siaddr:  0.0.0.0
DHCDISCOVER giaddr:  10.32.2.37
