Title:
  check_dhcp -s <hostaddress> doesn't work if dhcp-server answers with
  different next-server ip

Status in Nagios Plugins:
  Unknown
Status in “nagios-plugins” package in Ubuntu:
  Fix Released
Status in “nagios-plugins” source package in Precise:
  New

Bug description:
  [Impact]
  specific windows dhcp-servers can't be checked, only if a dhcp-server exists in a subnet. thats bad because faulty dhcp-servers will be detected as fine.

  [Test Case]
  setup a windows 2008 r2 dhcp server with the option boot-server set to an ip != dhcp-server and run check_dhcp -s <server ip> against it. it will receive a response but detect it as invalid because it uses the ip from set for the boot server (next-server).

  [Regression Potential]
  low, as only check_dhcp could be broken by the patch.
