I switched from root to 'nagios' with 'su -s /bin/bash nagios', then ran '/usr/lib/nagios/plugins/check_dhcp -v -s 172.16.9.3 -r 172.16.9.254 -i eth1 -m aa:bb:cc:dd:ee:ff'
This is the result: --- Requested server address: 172.16.9.3 Hardware address: aa:bb:cc:dd:ee:ff DHCP socket: 3 DHCPDISCOVER to 255.255.255.255 port 67 DHCPDISCOVER XID: 901953561 (0x35C2B819) 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 recv_result_1: 315 recv_result_2: 315 receive_dhcp_packet() result: 315 receive_dhcp_packet() source: 172.16.9.3 Result=OK DHCPOFFER from IP address 172.16.9.3 via 172.16.9.3 DHCPOFFER XID: 901953561 (0x35C2B819) DHCPOFFER chaddr: AABBCCDDEEFF DHCPOFFER ciaddr: 0.0.0.0 DHCPOFFER yiaddr: 172.16.9.254 DHCPOFFER siaddr: 172.16.9.3 DHCPOFFER giaddr: 0.0.0.0 Option: 53 (0x01) Option: 54 (0x04) Option: 51 (0x04) Option: 1 (0x04) Option: 6 (0x04) Option: 12 (0x0F) Option: 28 (0x04) Option: 42 (0x04) Option: 44 (0x04) Option: 15 (0x0A) Lease Time: 3600 seconds Renewal Time: 0 seconds Rebinding Time: 0 seconds Added offer from server @ 172.16.9.3 of IP address 172.16.9.254 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=172.16.9.3 Requested=172.16.9.3 OK: Received 1 DHCPOFFER(s), 1 of 1 requested servers responded, requested address (172.16.9.254) was offered, max lease time = 3600 sec. --- So it works, though the "Result=ERROR" thing looks strange.
