Hello, I would like to ask about a pure static KEA DHCP server setup, where:
- only the well-known clients with static reservations for their MACs will get reserved IP addrs (leases) - unknown clients/devices won't get anything (ideally no reply from DHCP server, or some kind of NAK) If yes, may I ask for a working demo config file - I mean related declarations of pools and client reservations... For my purposes, I am running a quite old, but working KEA 1.4 instance and would like to upgrade. To filter unwanted clients with unknown MACs, I had to create my own hook (extension written in .c) to accept the requests from registered clients only. And I would like to eliminate this solution... Pieces of my hook code: // std::cout << "pkt4_receive MAC : " << hwaddr->toText() << std::endl; ConstHostPtr host; ConstHostCollection reservations = HostMgr::instance().getAll(Host::IDENT_HWADDR, &hwaddr->hwaddr_[0], 6); host = reservations.empty() ? 0 : reservations.at<http://reservations.at>(0); ... if (!host) { LOG_INFO(user_chk_logger, USER_CHK_MAC_INVALID).arg(mac_info_str); // std::cout << "Host not found, setting status to NEXT_STEP_DROP" << std::endl; handle.setStatus(CalloutHandle::NEXT_STEP_DROP); } else { LOG_INFO(user_chk_logger, USER_CHK_MAC_VALID).arg(mac_info_str); // std::cout << "Host OK, accepting packtet" << std::endl; // std::cout << "Subnet ID is " << host->getIPv4SubnetID() << std::endl; } Thank you very much. Sincerely, Jan Rovner
