similar to: CentOS 4.6 - dhcp issue

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

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 {

Hello all, I''m using shorewall on a linux machine that has two interfaces, eth0 being connected on the internal network (10.10.10.0/24) and eth1 being connected to the external network. On eth0 the IP is statically configured to 10.10.10.254 and there is a dhcp server running for the machines in the private network. On eth1, the IP is dynamically assigned by my ISP modem that acts as

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

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]:

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

Package: logcheck-database Version: 1.2.23 Severity: minor Hi, a couple of minor corrections to the dhcp rule sets: First of all, the hostname matching parts need to include the "._-" signs (maybe . is not needed but it might be). Then when using failover, log lines of type DHCPDISCOVER and DHCPREQUEST may be entailed by the string ": load balance to peer <somestring>".

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.

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

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.

DHCP is working but dns updates not: i have this messages on my syslog then dhcpoffer: May 17

Hi, I'm trying to configure PXE syslinux to boot a diskless client but the client can't find the PXE boot image.
