[Nagios-users] check_dhcp not working

[Toto Capuccino]

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 10.2.1.1
DHCP problem: No DHCPOFFERs were received.

/usr/local/nagios/libexec#  ./check_dhcp -s 10.2.1.1 -r 10.2.10.98 -v
DHCP socket: 3
Hardware address: 000f20320a77
DHCPDISCOVER to 255.255.255.255 port 67
DHCPDISCOVER XID: 845057729 (0x325E8EC1)
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

I also want to check dhcp on other subnets separed with cisco routers, is that possible?

Thank  you.
