Hello, I want to run a check_dhcp on a remote server inside the same subnet but never get a reply : /usr/local/nagios/libexec# ./check_dhcp -s <a href="http://10.2.1.1">10.2.1.1</a> DHCP problem: No DHCPOFFERs were received. /usr/local/nagios/libexec# ./check_dhcp -s <a href="http://10.2.1.1">10.2.1.1</a> -r <a href="http://10.2.10.98">10.2.10.98</a> -v DHCP socket: 3 Hardware address: 000f20320a77 DHCPDISCOVER to <a href="http://255.255.255.255"> 255.255.255.255</a> port 67 DHCPDISCOVER XID: 845057729 (0x325E8EC1) DHCDISCOVER ciaddr: <a href="http://0.0.0.0">0.0.0.0</a> DHCDISCOVER yiaddr: <a href="http://0.0.0.0">0.0.0.0</a> DHCDISCOVER siaddr: <a href="http://0.0.0.0"> 0.0.0.0</a> DHCDISCOVER giaddr: <a href="http://0.0.0.0">0.0.0.0</a> 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.
