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). |
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?
