yes on that truly different machines note, I have noted than isc's dhcpd doesn't give a dhcpoffer back to it's own interface, hence I'm running my dhcp check from a different server to the dhcp server.
also make sure the dhcprequest is going out of the right interface (my defaulted to eth0 but this was not plugged it, I was using eth1) other than that, all the basic stuff, check iptables, perhaps try different versions of the plugin in case there is a bug, make sure your dhcp server is on the same subnet or you at least have a dhcp relay on your subnet etc etc. -h Hari Sekhon Marc Powell wrote: > >> -----Original Message----- >> From: Lacayo, Luis F [mailto:[EMAIL PROTECTED] >> Sent: Wednesday, June 27, 2007 3:07 PM >> To: Marc Powell; [email protected] >> Subject: RE: [Nagios-users] check_dhcp question... >> >> Here is the output of the verbose. >> >> [EMAIL PROTECTED] libexec]# ./check_dhcp -v -s 10.129.177.16 >> Requested server address: 10.129.177.16 >> DHCP socket: 3 >> Hardware address: 001438bbfc21 >> DHCPDISCOVER to 255.255.255.255 port 67 >> DHCPDISCOVER XID: 756149105 (0x2D11EB71) >> 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. >> > > I assume that this machine is on the same broadcast network as your DHCP > server and they are truly different machines.
