I also have a fully functioning DHCP server on eth0 (works perfectly with Parallels for Linux). The directions

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can

Hi - On my CentOS 4 cobbler server i am having some odd dhcp issues. There is only 1 dhcp server on the network and the cobbler box manages the dhcp. When i kick off the PXE install during the PXE phase things seem OK then when anaconda tried to get an IP sometimes things work out fine and other times it sits waiting for hostname/domainname. From the logs you can see that the mac requesting

Hey folks! I want to add a CentOS 5.2 domU to an existing server (Fedora 8) which was setup by another company. The Dom0 does not provide any other services but a BIND-DHCP-server (they deleted dnsmasq and installed bind). Don''t ask my why they did that. My new DomU is connected to eth0, which is a bridge. BIND also listens on eth0 to serve other machines. I start the install of centos

Package: logcheck-database Version: 1.2.39 Severity: normal I use dhcp3-server and a dhcp client which is Sony HDD video recorder CoCoon. The client not return client host name. In this case, dhcpd server assumed the client host name is (none).

I have a CentOS 4.6 server running dhcpd. One of my client devices (a Panasonic KX-HCM280A camera) is trying to get a lease from that server. I can see the device accept a lease (it is a reservation), however it always releases the reservation after about 25 seconds: Jul 10 10:30:49 stargate dhcpd: DHCPDISCOVER from 00:80:f0:56:46:30 via eth0 Jul 10 10:30:49 stargate dhcpd: DHCPOFFER on

I am having trouble with recovery. Today due to electrical work I powered down my networks Router / DHCP server. My Centos 7 host machines lost their DHCP lease (they are actually static leases). Once I power my Router / DHCP server back up none of my virtual machine were accessible. It appears that when the DHCP lease was lost on the virt server the bridge of the KVM guest were all losts. A

Hello, After asking around in #centos and other linux related IRC channels, here I am, bugging all of you. brace for the long post. (tldr: dhclient loses virtual interface ips) I set up a system to deploy statically assigned IPs to physical and virtual interfaces to a number of (virtual) machines. I have a DHCPD with an entry for each virtual ip in the form of host eth0-1.virt1.test.it {

Hi, I'm trying to configure PXE syslinux to boot a diskless client but the client can't find the PXE boot image. I've configured the DHCP server as follows: ---------------------------- # cat /etc/dhcp3/dhcpd.conf option domain-name "cluster.net"; option domain-name-servers 10.0.0.1; default-lease-time 6048; max-lease-time 604800; log-facility local7; subnet 10.0.0.0

I've found a problem, and I think it is in syslinux (specifically when it tries to load ldlinux.e64 under hyper-V). I have a physical computer with a Gigabyte GA-P85-D3 motherboard that successfully pxeboots using the EFI images, and I hold that up as exhibit 1 that my deployment environment works. It also implies that the syslinux.efi image works in some cases, but not in all. My Hyper-V

Dear folks, We are installing a large diskless cluster using CentOS 5.1. The hardware is pretty new - Supermicro X7DWT boards with Harpertown CPUs. Unfortunately we have some PXE-related problems described by the following scenario: 1) Set up DHCP, TFTP and NFS on a server, prepare PXE kernel and initrd - fine. 2) Start up the node using PXE for the first time - fine. 3) Reboot the node - PXE

Rowland, You're absolutely right - with '128' both DHCP servers listen and *may* reply, therefore besides failover provide load balancing. Even if both servers respond with *Offers* to the client, the client will select one and issue *one Request* to the selected server. E.g., below is a log records from my failover DHCP (192.168.0.2) server: May 17 00:09:37 s-dhcpd-2 dhcpd[1578]:

Hi, syslinux: I use pxelinux to install Linux from network. Currently, my problem is: The first time, the client machine can acquire the IP address from dhcp server but at the second time, the client machine cannot acquire the IP again. The only way is to remove the /var/lib/dhcp/dhcpd.leases file in server and restart the dhcpd service. Then the client machine can get the IP again.

I use official manual from wiki.samba.org for install samba 4.6.3 (from source) with bind_dlz on bind 9.9.10 (from source too). My OS is Debian Jessie x64 8.8 netinst. I use https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records_with_BIND9 article for dynamic dhcp updates on dns zones. DHCP is working but dns updates not: i have this messages on my syslog then dhcpoffer: May 17
