From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0) Description of problem: DHCPD sends ACK on a renew request on a pool not assigned to an interface whereas it should send out a NAK. Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: configure a dhcp server w/ multiple interfaces (in this case 5) create pools of addresses for 4 of the 5 and no pool for the 5th. 1. acquire an address from eth0, e.g. 134.134.16.25 2. Disconnect from eth0 network 3. Connect to eth1 network. 4. Client sends a renew 134.134.16.25 to dhcp on eth1 Actual Results: 5. DHCP responds with an ACK out eth1 for 134.134.16.25 Expected Results: DHCP should have sent a NAK out eth1 to the client, then the client would initiate discovery. Additional info: Also seen the ACK and/or NAK getting sent out eth0 and eth4. eth1 and eth4 share an IRQ, all other adapters have their own IRQ. Is there an update that takes care of this issue?
DHCP information: redhat 7.1, kernel: 2.4.2-2 dhcp-2.0p15-4.src.rpm
Please check Current release of dhcp 3.0 to see if this solves the problem
I believe adding an: authoritative; line to the beginning of dhcpd.conf causes the NAKs to be sent out if renew requests are receieved from clients w/ IPs from other subnets. This functionality is present in the release mentioned, so upgrading is not necessary (although I did so).
